An integrated design process identifies opportunities to achieve synergies across disciplines and building systems throughout the planning and design phases and beyond.[1] For example, decision-making about building shape, orientation, and window placement relate to several green building considerations and relies on the knowledge of multiple disciplines; these building envelope strategies impact heating and cooling loads as well as occupant satisfaction and even productivity, a function of thermal comfort and daylighting.[2] With an integrated design process that considers these multiple benefits, and sometimes trade-offs among them, it is much more likely that the building performs as intended and achieves projected cost savings.<br />\nMany green building strategies also convey resiliency benefits or “the ability to prepare and plan for, absorb, recover from, and more successfully adapt to adverse events.”[3] At the building level, these include an emphasis on daylighting, superior insulation values, thermal massing and on-site renewable energy, and water harvesting. These strategies reduce the need for electricity for lighting, cooling, and other critical functions, making buildings more resilient to power outages and disruptive events.<br />\nA successful integrative design process challenges project teams to design, build, and manage high-performance buildings that are both green and resilient.</p>\n<p>How to Implement an Integrated Design Process<br />\nA truly integrated design process includes ongoing interactions among the entire project team and uses tools and modeling software to support and reinforce design integration.<br />\nThe following are standards and guidelines for incorporating an integrated design process.</p>\n<p>The American National Standards Institute (ANSI) Integrative Process (IP) – ANSI Consensus National Standard Guide© – Design and Construction of Sustainable Buildings and Communities identify best practices for developing an integrated process.[4]<br />\nThe American Institute of Architect (AIA) Integrated Project Delivery (IPD) outlines a step-by-step process for the client, design, and construction teams to achieve IPD goals.[5]<br />\nLEED v4 for Building Design and Construction credit requirements for the Integrative Process include an analysis of at least two energy-related systems (i.e., shading, renewable energy opportunities), and two water-related systems (i.e., on-site rainwater and graywater, cooling tower water demand), and documentation on how this analysis informed building site and design decisions.[6]<br />\nRELi,[7] a national consensus standard for resilient design requires a “Panoramic Approach” that includes “Pre-Planning and Discovery” and “Systems Thinking Design.”[8]</p>\n<p>Example<br />\nChesapeake Bay Brock Environmental Center, Virginia Beach, VA.<br />\nThe integrated design process for the Brock Environmental Center included early charrettes with the client and neighbors, collaboration with the architect, engineer, owner, green consultant, and contractor throughout the design process, and a full-day, pre-design charrette with stakeholders from all design disciplines including local officials, community representatives, and Living Building Challenge (LBC) and LEED experts.[9] Energy and climate simulation tools informed the decision to utilize on-site wind energy and early discussions with regulatory agencies made possible the collection of rainwater for potable use.[10]<br />\nBenefits<br />\nEarly coordination regarding the interactions of complex building systems can maximize the effectiveness and output of these systems and reduce total project costs.<br />\nAn integrated design process can result in a project that:</p>\n<p>Increases the opportunity to achieve more aggressive sustainability goals<br />\nOptimizes energy efficiency and incorporates alternative energy solutions<br />\nRecognizes and plans for synergies between green building and resilient design<br />\nMoves beyond minimizing environmental impacts to creating positive, regenerative impacts on the environment<br />\nMaximizes cost effectiveness</p>\n<p>Costs<br />\nThe integrated design process can both minimize incremental capital cost and result in operational savings. Capital cost can be redistributed to achieve high-performance goals without incremental costs. For example, the opportunity to eliminate or reduce the size of equipment or systems can offset the higher first cost of some energy efficiency strategies.  An integrated approach can also reduce operational expenditures through increased communication among the project team, resulting in a more efficient design.<br />\nCosts associated with an integrated design process may include things like additional consultant fees to facilitate a goal-setting workshop and time and associated costs of having project team members participate in additional meetings and coordination.<br />\nResiliency<br />\nAn integrated design process provides an opportunity for project teams to incorporate resilient design strategies into green building practice. Project teams may want to consider the following when identifying and evaluating green building strategies that also offer resiliency benefits.[11]</p>\n<p>Understand regional impacts: Identify climate impacts for the building’s location.<br />\nEvaluate performance targets: Understand how the building performs under current peak climate conditions.<br />\nConduct a scenario analysis: Analyze how the building responds to projected climate impacts, modeling different system options under a variety of climatic conditions.<br />\nConsider resilient design strategies: Evaluate resilient design strategies that provide passive or efficient responses to more extreme climate events such as higher or lower temperatures, higher wind speeds, and increased or decreased precipitation levels, to maintain occupant comfort while preventing increased energy use.</p>\n<p>&nbsp;<br />\n[1] USGBC LEED v4 for Building Design and Construction.

For example, during the operational phase, the LCA for a deck includes the impact of the resources used for cleaning (e.g., energy, water, detergents), staining, or replacing boards.[3]<br />\nDefined environmental impact areas commonly include: [4]</p>\n<p>Climate change (“carbon footprint”)<br />\nAcidification (“acid rain”)<br />\nEutrophication (“algal bloom”)<br />\nPhotochemical oxidant creation (“summer smog”)<br />\nOzone depletion (“the ozone hole”)</p>\n<p>LCA’s support informed decision-making by providing a standardized system for verifying environmental footprints and claims, identifying environmental trade-offs, and making relative comparisons between different design paths or product choices.<br />\nWhile LCA’s take into account environmental impacts, Life Cycle Cost Analysis (LCCA) evaluates the life-cycle costs of building designs and systems (see Life Cycle Cost Analysis (LCCA)).  Together, LCA’s and LCCA’s provide the essential components of a comprehensive cost-benefit analysis.<br />\nHow to Implement Life Cycle Assessment (LCA)<br />\nIncreasingly, consumers and regulatory agencies are asking businesses and product manufacturers to provide environmental product declarations, which use LCA data to report the environmental impacts of their products, processes, and services (see Sustainable Materials).  In the building sector, green building programs such as LEED, offer credits for completing a whole building LCA as part of the integrated design process.[5] LEED credits are also offered to promote the reuse of historic buildings and the renovation of abandoned or blighted buildings.[6] Likewise, the field of LCA continues to evolve as the quality and completeness of LCA data improves and LCA methodologies are tested and refined.<br />\nThe complete process of LCA includes:[7]</p>\n<p>Defining goals and assessment boundaries.<br />\nCollecting information on materials and design alternative.<br />\nUsing accredited LCA assessment tools to perform impact calculations.<br />\nCompiling and interpreting results.<br />\nDocumenting the process and providing assessment reports.</p>\n<p>LCA reports are often complex and technical in nature, but current tools attempt to summarize LCA information in a manageable format specifically targeted to design professionals. Tools are available for both whole building and product level LCA’s.<br />\nAthena EcoCalculator is a free online LCA calculator that provides a streamlined report of building’s footprint using LCA data on hundreds of common building products.<br />\nAthena Impact Estimator for Buildings is a free LCA-based software package for designers and building professionals that provides environmental impact data on over 1,000 structural and envelope assembly combinations.<br />\nBuilding for Economic and Environmental Software (BEES) is a free online tool for selecting cost-effective and environmentally preferable building products and includes actual environmental and economic performance data for 200+ building products.<br />\nBenefits<br />\nThe main benefit to LCA is credible, transparent data that informs greener design and product decisions and the associated cost savings and environmental benefits from reduced resource consumption, pollution, and waste.<br />\nCosts<br />\nThe costs for performing an LCA depend on the scope and complexity of the building project, data availability and on whether in-house expertise or an independent consulting service completes the analysis. Several free online tools and resources are available to help owners and designers perform LCA’s (see Resources). Costs for performing an LCA typically include labor costs for data collection and data input and the interpretation and reporting of results.<br />\nResiliency<br />\nAn LCA can identify and evaluate the environmental benefits of green building designs and products that enhance building resiliency. These may include specific design inputs for address increasing heat, more intense precipitation, or rising sea levels. For example, resilient strategies may include cooling and shading features (e.g., cool pavements and cool roofs), improving the efficiency of building envelopes (e.g., insulation, windows, exterior walls), planning for increased failure or reduced efficiency of electrical or mechanical systems (e.g., battery storage), and providing passive solar cooling and ventilation features (e.g., Properly-Sized HVAC systems).[8] LCA’s focused on resilient design can also consider the avoided costs or resiliency benefits of avoided power outages, such as reduced business closures, health, and safety hazards, food spoilage, and inconvenience from schedule disruptions.

Green building features generally have higher initial costs compared to conventional features but offer operational savings over time through decreased resource use (e.g., energy, water), maintenance, and disposal fees.[1] LCCA takes into account the overall costs of purchasing, operating, maintaining, and disposing of a building or building system, which the initial purchase price does not reflect. Comparing the life cycle costs of various options helps to determine the most cost-effective choice for a comparable building design or system in terms of function and performance by translating this data into dollar amounts and providing information about how long it takes an investment to pay for itself (e.g., internal rate of return, savings-to-investment ratio, payback period).  For existing buildings, LCC also compares the costs of not doing something (e.g., replacing windows) by considering any future maintenance and operational costs.<br />\nWhile LCCA’s take into account the life-cycle costs of building designs and systems, a Life-Cycle Assessment (LCA) evaluates the environmental impacts of products, services, and systems (see Life-Cycle Assessment (LCA)).[2] Together, LCCA’s and LCA’s provide the essential components of a comprehensive cost-benefit analysis.<br />\nHow to Perform a Life Cycle Cost Analysis (LCCA)<br />\nPerform the LCCA early in the renovation or upgrade project and as part of an integrated design process to allow sufficient time and resources to refine the design and ensure the highest quality product for the lowest cost (see Integrated Design Process). Depending on project team expertise, hire a consulting service or conduct the LCCA in-house. Project teams should refer to the ASTM standard life-cycle cost method, which covers the costs of initial investment, replacement, operation, maintenance and repair, and disposal.[3]<br />\nThe first task of an LCCA involves determining the costs and benefits of alternative project options. Next, project teams can conduct several sensitivity analyses that include variations in the discount rate, study period or building lifespan, and energy escalation rates.<br />\nThe discount rate is a measure that decreases the value of dollars spent or received in the future, so future costs and returns are worth progressively less in terms of today’s dollars. The interest rate used for discounting is a rate that reflects an investor’s opportunity cost of money over time. The LCCA method converts cash flows to present values by discounting them to a common point in time, usually the base date.<br />\nThe US Department of Energy (US DOE) suggests a real discount rate of 3.0%, based on a 12-month average of long-term Treasury bond rates.[4]<br />\nStudy period or building lifespan refers to the length of time the LCCA covers. The study period for non-residential buildings typically falls between 20 and 40 years and may reflect a shorter period than the actual intended life of the facility.<br />\nEnergy escalation rates refer to projected average annual energy price increases obtained either from the supplier or from energy price escalation rates published annually on April 1 by US DOE in Energy Price Indices and Discount Factors for Life-Cycle Cost Analysis, Annual Supplement to NIST Handbook 135.[5]<br />\nThere are several online tools for performing an LCCA and links to more information in the Resources section below.<br />\nExample<br />\nNew Jersey Meadowlands Commission: Observatory and Classroom Building LCCA, Lyndhurst, NJ.<br />\nThe Rutgers Center for Green Building conducted an LCCA of the Meadowlands Environmental Center, a LEED Platinum building, modeling the building’s metabolic flows, including heating, lighting, ventilation, water, and power consumption, and waste production. The result was a quantification of any added capital investments encountered during construction and commissioning of the LEED-compliant structure, as well as a use-phase evaluation of the economic impacts of adherence to a green building standard.<br />\nBesides the Photovoltaic System (PV), the study results showed that daylight sensors provided the most cost-effective green feature, providing savings under all of the modeled situations as well as the most significant savings compared to other green features. The HVAC system projected savings consistently, although of lower value than the daylight sensors. Insulation provided savings under a majority of circumstances but showed a low return value in all cases. The study noted that the value of SREC’s directly impacts the cost-effectiveness of the photovoltaic (PV) system.</p>\n<p>Benefits<br />\nLCCA’s can offer environmental and monetary benefits for existing building upgrades and renovations by revealing the most environmentally-friendly and cost-effective solutions for the long run that purchase price alone cannot quantify. Potential benefits include reduced energy, water, and fuel consumption and cost savings on utility bills, maintenance, replacement, and end-of-life disposal costs. While an LCCA cannot remove all uncertainty surrounding a building project, the results equip the design team with the means to identify the optimal balance between green design and economic efficiency.<br />\nCosts<br />\nThe costs for performing an LCCA depend on the scope and complexity of the building upgrade and renovation project and on whether in-house expertise or an independent consulting service completes the analysis. Several free online tools and resources are available to help owners and developers perform an initial LCCA (see Resources). Costs for performing an LCCA typically include labor costs for data collection, energy modeling (if necessary), LCCA calculations, and the interpretation and reporting of results.<br />\nResiliency<br />\nLCCA’s can identify and evaluate the costs and benefits of green building strategies that enhance building resiliency. While LCCAs and energy modeling typically use historical weather data, specific, regional, and forward-looking climate data can be used in energy models to inform resilient building design.[6] For example, in the NJMC study mentioned above, the team ran an energy model scenario according to low-emissions mid-century predictions of climate change developed by the Northeast Climate Impacts Assessment (NECIA).[7]<br />\nLCCA’s can take into account resiliency objectives. These may include specific design inputs to address increasing heat, more intense precipitation, or rising sea levels, including cooling and shading buildings, improving the efficiency of building envelopes, utilizing green roofs and landscape elements, planning for increased failure or reduced efficiency of electrical or mechanical systems, and providing passive solar cooling and ventilation features.[8] LCCA’s focused on resilient design can also consider the avoided costs or resiliency benefits of avoided power outages, such as reduced business closures, health, and safety hazards, food spoilage, and inconvenience from schedule disruptions.[9]<br />\n[1] Whole Building Design Guide (WBDG). 2016.

Changes in design or improper installation can lead to systems working inefficiently. Additionally, building systems degrade and lose efficiency over time make re-commissioning and ongoing commissioning essential steps in the overall quality assurance process (see Figure 1).</p>\n<p>How to Implement Re-Commissioning<br />\nThe first step in the re-commissioning process is to designate the re-commissioning team, which often includes the Commissioning Agent (CxA), Building Owner, Construction Manager/General Contractor, Contractors, maintenance and operations personnel, and occupants. The Building Commissioning Association (BCxA) recommends hiring a third-party independent CxA with excellent written and verbal communication skills, current engineering knowledge and extensive hands-on field experience regarding building systems, including principles of building system performance and system start-up, balancing, testing and troubleshooting, as well as knowledge and experience with building operation and maintenance procedures and the building and design process.[2]<br />\nThe re-commissioning team assures the completion on all of the steps in the re-commissioning process and the realization of building objectives and develops the building re-commissioning plan, which outlines and organizes the commissioning process schedule and allocation of resources and includes details of systems tests and procedures (i.e., energy audit), system and equipment checklists, and testing and documentation responsibilities. The re-commissioning process should include an energy audit, which provides an analysis of the building’s energy use and potential for savings. LEED requires energy audits to meet both the requirements of the ASHRAE preliminary energy use analysis and an ASHRAE Level 1 walk-through assessment identified in the ASHRAE Procedures for Commercial Building Energy Audits or equivalent.[3]<br />\nBuilding re-commissioning plans may include some or all of the following building systems and green building elements (as applicable):[4]</p>\n<p>HVAC systems (control settings and sequencing)<br />\nBuilding assembly (envelope, interior, paths of egress)<br />\nConveying systems (elevators and escalators)<br />\nProtective systems (fire suppression, lightning protection)<br />\nPlumbing (water distribution, sanitary or stormwater)<br />\nElectrical (power distribution, lighting)<br />\nCommunication systems (telecom, wireless networks, sound, video)<br />\nAlarm Systems (fault detection, security, leak detection)<br />\nIndoor air quality (moisture, airborne particles)<br />\nIndoor environmental quality (acoustics, thermal comfort)<br />\nRenewable energy (photovoltaics, wind energy)<br />\nSmart building technology (advanced metering, building automation systems)<br />\nEnergy storage and back-up power generation systems (ice storage, batteries)<br />\nAlternative water reuse systems (greywater recycling, composting toilets)</p>\n<p>The re-commissioning process provides testing and documentation that establishes valuable performance benchmarks, and a baseline for the future operation and the ongoing commissioning of the building. Re-commissioning teams may consider issuing an occupant survey before re-commissioning to identify areas of concern and focus. The final re-commissioning report provides building upgrade recommendations and operations and maintenance improvement opportunities and describes the potential improvement, estimated implementation costs, and savings for each opportunity.<br />\nFor a more detailed overview of the re-commissioning process, including retro-commissioning and ongoing commissioning see the Building Commissioning Association’s Existing Building Commissioning Best Practices and Tools Handbook.<br />\nBenefits</p>\n<p>Optimized building systems and quality assurance.[5]<br />\nLower utility bills through reduced energy savings of 14-16%.[6]<br />\nImproved indoor environmental quality and occupant comfort.<br />\nFewer building system issues at building turnover.<br />\nEnhanced operation and maintenance.</p>\n<p>Costs<br />\nThe cost of not re-commissioning equals the costs of correcting mistakes plus the costs of inefficient operations.[7] Re-commissioning for existing buildings costs on average $.30 per square foot for commissioning agent services.[8],[9] Reduce the costs of on-going re-commissioning by installing systems that make that process more manageable such as smart metering (see Smart Metering). The payback period for costs in extra time and labor and parts are around one to four years.[10] Other estimates find that payback can be less than two years and often less than six months.[11]<br />\nSee the New Jersey Office of Clean Energy for available programs and incentives related to commissioning.<br />\nResiliency<br />\nRe-commissioning contributes to a building’s resiliency by providing feedback on the status of critical building systems and notifying building operators when and where a problem exists, ensuring that a building performs optimally during both normal operations and emergencies. Re-commissioning identifies opportunities for energy savings and if implemented, help to reduce stress on the grid and the likelihood of grid failures.<br />\n&nbsp;<br />\n[1] Building Commissioning Association (BCxA). 2018.

Transit Oriented Development (TOD) concentrates development around transit stations, such as train, light rail, and bus stations, and other amenities to create places for people to live, work, and play without requiring the use of a car.[3]</p>\n<p>How to Incorporate Alternative Transportation and TOD<br />\nThere are several general topics regarding alternative transportation to consider when incorporating alternative transportation strategies into an existing commercial project that can also help to earn your project LEED credits.</p>\n<p>Proximity to existing public transportation, pedestrian, and bicycle networks and establishing a shuttle service if beyond a short walk away.<br />\nProximity to existing infrastructure, services and economic activity such as stores, schools, offices, and parks.<br />\nMinimizing on-site parking and providing bicycle changing facilities and storage.[4]<br />\nProviding covered areas for people awaiting carpool/vanpool rides and drop-off/pick-up zones for vehicles.<br />\nProviding facilities to encourage energy-efficient vehicle use, such as two-way electric plug-in charging stations that enable EVs to both draw electricity from and supply electricity to the grid, and liquid or gas alternative fueling facilities or a battery switching station.</p>\n<p>Many local programs assist with alternative transportation options such as the Hudson County Transportation Management Authority that offers rideshare, carpool, and vanpool services as well as other useful information for commuters.<br />\nBusinesses and organizations can implement telecommuting policies that contribute to sustainable workplace practices by allowing employees to communicate via telephone and computers to accomplish tasks that traditionally occur in central office spaces, reducing traffic congestion and strain on transportation systems, fuel consumption, and associated emissions and air quality issues.[5]<br />\nTOD begins with site selection near transit hubs. Consider local regulations and interest in transit hub development to reduce delays and conflict. Identify special zoning and permit systems designed to expedite efficient redevelopment of urban centers.<br />\nThe New Jersey Department of Transportation and New Jersey Transit leads a multi-agency partnership known as the Transit Village Initiative that encourages pedestrian-friendly neighborhoods and community revitalization. This program aims to reduce traffic congestion, improve air quality and promote growth in areas where infrastructure and public transit already exist.[6]<br />\nExamples<br />\nCranford Crossing, Cranford, NJ.<br />\nCranford Crossing, a mixed-use redevelopment integrated into Cranford’s pedestrian-friendly environment and located one block from Cranford’s train station.<br />\nRegional Plan Association Report – The Fourth Regional Plan<br />\nThis report provides examples of several Transit Oriented Developments (TODs) throughout NJ that encourage alternative transportation.<br />\nBenefits<br />\nEncouraging the use of alternative transportation options provides benefits for developers, property owners, and building occupants as well as benefits for the environment and the community. Alternative transportation reduces automobile congestion, fossil fuel consumption and carbon emissions.[7] Some forms of alternative transportation also provide options for healthier lifestyle choices. Proximity to public transportation and neighborhood services can improve quality of life and reduce commuting stress, all of which provide positive marketing opportunities for a new commercial facility. Businesses can participate in programs that encourage alternative transportation strategies such as New Jersey Smart Workplaces, a partnership between NJ DOT, NJ Transit, and the state’s Transportation Management Association, that recognizes organizations and individuals who help reduce traffic congestion and improve air quality.[8]<br />\nCosts<br />\nIncluding alternative transportation options in the initial design phase and locating projects near rapid transit helps to reduce upfront project costs. Transit-oriented design saves developers money by capitalizing on existing infrastructure and upgrades rather than relying on the developer to provide new infrastructure and parking, a significant redevelopment cost (see Brownfield and Infill sites).<br />\nBuilding excessive parking adds to construction costs and may contribute to environmental problems such as the heat island effect and increased stormwater runoff (see High Reflectance Hardscape Materials and Pervious Hardscape Materials). Providing excessive parking also encourages driving, which causes congestion, air pollution, and contributes to the emission of greenhouse gases. The fewer spaces dedicated to parking, the more for open space, parks, community rooms, or additional building square footage.[9]<br />\nCosts associated with providing facilities and equipment that encourage alternative transportation options such as biking and walking vary by project and may include costs to provide shower and changing facilities. Bicycle racks can accommodate about ten bikes for the same space and cost as one parking space. The cost of adding bike lanes depends on the existing condition of the roads.  The cost of adding a sidewalk is about $70 per linear foot along existing roads, though it can be significantly less if included as part of the initial road construction work.[10]<br />\nResiliency<br />\nLocating buildings with access to a variety of alternative transportation options increases a building and its occupant’s resiliency by providing access to a seamless network of diverse mobility choices fueled by multiple energy sources and insulated from disruptions caused by extreme weather events, security threats, and disaster-related scenarios.[11] Telecommuting and flexible work schedules reduce congestion and strain on transportation systems, especially during vulnerable times such as storms and inclement weather. Providing bi-directional electric-plug in charging stations supports alternative fuel vehicle adoption, and vehicle-to-grid applications, which enable fully charged EV’s to supply power to the grid during emergencies or supply shortages (see Energy Storage and Backup Power Generation).[12]<br />\nTOD encourages community interaction that can lead to better cultural understanding, stronger social ties, and in turn, more resilient communities that come together to support each other in times of need. Also, TOD helps reduce the number of cars on the road, an added benefit, especially during times of mandatory evacuations when roads need to be accessible to first responders.<br />\nA study by the Federal Highway Administration, “The Post Hurricane Sandy Transportation Resilience Study in New York-New Jersey-Connecticut,” provides an assessment of the region’s transportation system’s resilience to climate, sea level rise and extreme weather leveraging lessons learned from Hurricane Sandy as well as future climate projections and identifies strategies to reduce and manage extreme weather vulnerabilities.[13]<br />\n&nbsp;<br />\n[1] USGBC.

Compost is the by-product of decaying organic matter like vegetable scraps. Material that can be composted (e.g., food scraps and landscape waste) make up 30% of the material we discard.[1] Composting this material instead of sending it to a landfill turns it into a useful resource that builds nutrient-rich organic soil. Vermicomposting is composting facilitated by worms (i.e., generally red wiggler worms Eisenia foetida). The worms help expedite the breakdown of the organic matter; vermicomposting provides a space-saving option for offices and businesses with limited space.[2]</p>\n<p>How to Implement Composting<br />\nOrganic matter can be collected separately to create compost including kitchen scraps (plant and animal), paper products, wood scraps and grass clippings. Grass clippings can also be left directly on the lawn. This saves time and helps recycle nutrients back into the soil.[3],[4] Depending on the volume and type of waste generated, there are two ways to compost non-lawn waste: choose a pick-up service or choose to compost waste and use it on site. The decision should be Based the decision to compose on how much organic matter you collect regularly, whether the space exists to convert refuse to compost, whether there is a need for nutrient-rich soil on-site (e.g.,  landscaping, planting, etc.), and whether waste is primarily plant (e.g., leaves and wood chips) or animal matter, and availability of a pick-up service in your area. Some municipalities offer composting drop-off/pick-up services (see Hoboken – Composting). If dropping off materials, be sure to check what waste types are accepted at composting facilities: NJ DEP Solid &amp; Hazardous Waste: Compost Facilities. If composting is not possible on-site, local composting programs or community garden projects often accept items like grass clippings and food waste for their compost operations.[5] If composting in-house, plan for ongoing maintenance of the composting process.<br />\nOutdoor Composting Process:<br />\nCompost outdoors with either a simple pile in the yard or a compost bin. First, decide on a location for the pile or bin that is shady and relatively dry. Collect roughly equal amounts of nitrogen-rich (e.g., food scraps) and carbon-rich (e.g., dead leaves, twigs) wastes. Add materials to the pile or bin as they are collected while also adding a little water each time. Once the pile is established, add grass clippings, green leaves, and mix to make sure the food scraps are inside the pile. Use the bin lid or a tarp to cover the pile to retain moisture and heat. When the material at the bottom of the pile is rich in organic matter and dark in color, it is ready to use. This could take anywhere from two months to a year, depending on the contents of the compost pile and the outdoor conditions.[6]<br />\nIndoor Composting Process:[7]<br />\nIf outdoor space is limited or unavailable, composting can be done inside on a smaller scale. Purchase or build indoor compost bins, that when managed correctly, do not smell or attract pests.[8] Indoor composting can be performed in one of two ways: anaerobic (i.e., without oxygen) or aerobic (i.e., with oxygen). Choose from anaerobic composters that can be placed on a countertop or under a sink or aerobic composter that use a worm bin.  These can either be purchased or made quite easily.<br />\nBuilding a Worm Bin (Vermicomposting)[9]</p>\n<p>In a plastic storage container, place about 8-12 inches of bedding material such as potting soil, leaves, grass clipping, and newspaper strips. Purchase worms, typically red wiggler, to place in the bin. In addition, drill several air holes into the lid of the bin and make sure the bedding is moist and loosely placed in the bin to ensure proper air circulation.<br />\nAdd about 1 lb of red worms to the bin.<br />\nPlace food scraps, except animal products (e.g., meat, grease, cheese, etc.) under the bedding. Worms can eat about 3 to 3.5 pounds of kitchen waste per week.<br />\nKeep the bin covered to retain heat and moisture. Check the box every day or two for moisture. If the edges begin to look dry, add some water.<br />\nStore the bin in a warm dark place since the worms do not like light and can freeze if it gets too cold.<br />\nHarvest compost when it is a dark, rich color to use in a garden or in potted plants.</p>\n<p>Order worm bins or make them a plastic storage bin. For more information on worm bins and composting indoors visit: Rutgers Cooperative Research &amp; Extension</p>\n<p>Example<br />\nCampbell Soup Company Headquarters, Camden, NJ<br />\nCampbell initiated a comprehensive waste reduction program, including composting, in 2014. That year, they diverted 2,776 tons of waste from going to the landfill through composting.<br />\nBenefits</p>\n<p>Saves money on waste management<br />\nReduces landfill waste; reducing the production of methane, a greenhouse gas (GHG).<br />\nImproves landscapes through improved soil structure, stabilized pH and suppressing plant diseases[10]<br />\nProvides opportunities to garden and grow produce on-site</p>\n<p>Costs<br />\nThe small up-front costs can be quickly offset by the benefits of waste reduction and the use of compost on-site instead of purchasing fertilizer.<br />\nFull size outdoor bins can range in price from $26 – $500. For indoor composting activities, composter prices range from $40 – $300, and small simple collection canisters as low as $20.[11] Worm/vermicompost bins can be made relatively easily[12] or purchased (average $60-100 each)[13] and worms can be purchased for about $20-$40.00/lb (2 lbs to 1 lb of food scraps).[14] Mature compost can also minimize the amount of fertilizer needed, therefore saving on the cost of purchasing fertilizer. Finally, in areas where garbage is collected on a pay per bag basis, reducing the amount of trash by composting food scraps and paper saves money in trash collection fees.[15]<br />\nResiliency<br />\nComposting increases local community resilience by reducing stress on the waste management system, emissions from landfill gas and trash burning, and the release of pollutants. Compost enhances soil health, tilth (or physical condition), aeration, and water holding capacity, which support healthy plant and microorganism populations that are more resilient to ecosystem disturbances.[16] Composting also provides stormwater management and erosion control benefits.<br />\n[1] US EPA.

Stormwater runoff occurs when precipitation, in all forms, falls on land or impervious surfaces and does not infiltrate into the ground. When the runoff flows over the land or impermeable surfaces, including paved surfaces and building rooftops, it combines with pollutants such as debris, chemicals, and sediments. This polluted stormwater can negatively affect the hydrology and water quality of local water sources, resulting in habitat modification and loss, increased flooding, decreased biological diversity, increased sedimentation and erosion, contaminated drinking water, and forced beach closings due to health threats to swimmers.[1]<br />\nSite and stormwater management includes both Low Impact Development (also known as nonstructural strategies) and Green Infrastructure. Low Impact Development is the concept of designing a site to reduce the negative environmental impacts. Design techniques include[2]</p>\n<p>Preserving stream buffers<br />\nMinimizing the number of trees cut down during construction<br />\nReducing the use of heavy equipment<br />\nSelecting soils and vegetation beneficial to the site<br />\nUtilizing green infrastructure practices that treat stormwater through soil and vegetation</p>\n<p>The NJ Department of Environmental Protection’s Stormwater Best Management Practices Manual provides guidance on Low Impact Development strategies for new and existing projects in New Jersey.<br />\nGreen Infrastructure refers to stormwater management practices that capture, filter, absorb, and reuse stormwater, restoring the natural water cycle, reducing stormwater runoff, promoting infiltration, and enhancing evapotranspiration.[3] For example, green infrastructure can effectively turn parking lot islands, street medians, tree planter boxes, and landscaped areas near buildings into specialized stormwater treatment systems. Developers and property owners can redesign parking lots to reduce impervious coverage and increase stormwater infiltration. Innovative site and stormwater management designs may also include vegetated or green roofs, methods for capturing and reusing rainwater, and the use of pervious paving materials in low traffic areas, parking areas, and walking paths.<br />\nThe NJ DEP’s Green Infrastructure for New Jersey website provides informational fact sheets on common green infrastructure practices, including rain gardens/bioretention basins, grass swales, constructed gravel wetlands, and rain barrels. The Rutgers NJ Agricultural Experiment Station – Water Resources Program – Green Infrastructure Guidance Manual for New Jersey provides detailed information for the identification, design, and implementation of green infrastructure practices throughout New Jersey.<br />\nHow to Integrate Site and Stormwater Management<br />\nBoth LEED v4.1 Operations &amp; Maintenance (O+M), and SITES require stormwater management as part of their certification systems. Under Sustainable Sites, LEED O+M awards points for rainwater and site management strategies. SITES offers a comprehensive, performance-based rating system for sustainable landscapes. SITES certification applies to new construction projects as well as existing sites that include significant renovations (with or without buildings). Projects constructed within the last two years with a minimum of 2,000 square feet qualify for certification.<br />\nExisting commercial projects that impact the site should have a site protection plan included in the contract documents. A site protection plan protects the natural resources of a project site and adjacent areas and achieves compliance with local laws and codes. Existing trees and vegetation, healthy soils and natural hydrologic systems on a site are all valuable resources to consider protecting before a construction project begins.<br />\nThe sections below focus on the redesign of landscaping and incorporation of pervious paving materials, rain gardens, and vegetated roofs as ways to reduce a current commercial building’s stormwater runoff and incorporate best management practices for site development.<br />\nNative and Adapted Plants<br />\nConsider incorporating a native NJ habitat with plants adapted for the site. A native plant species thrive naturally in a particular region, ecosystem or habitat without direct or indirect human actions.[4] Adapted plants have evolved to the physical conditions such as soil, climate, and geology of a site but were not formally part of the natural ecosystem.[5] Invasive plants grow quickly and aggressively, often displacing native plants and adversely impacting native wildlife, local food sources, and pollination.[6]<br />\nLandscaping with plants that are native and adapted to the Mid-Atlantic geographic region nurtures a diverse and healthy ecosystem and saves time and money on maintenance. Diverse native habitats resist disease and reduce the need for synthetic pesticides, increase biodiversity and provide habitat for native wildlife, reduce stormwater runoff and mitigate flooding, and provide an alternative to the time-consuming, energy-intensive, and water-inefficient practices of lawn and turf care.<br />\nThe Native Plant Society of New Jersey provides a list of NJ native plants by County.<br />\nSome projects may be eligible for the Wildlife Habitat Incentives Program. Resources such as Jersey-Friendly Yards offer plant information and an easily searchable plant database.<br />\nPervious Hardscape Materials<br />\nPervious paving systems absorb water rather than diverting water into underlying soils, reducing runoff and treating pollutants as water passes through soils and replenishes groundwater.[7] Pervious surfaces include pervious concrete, porous asphalt, interlocking concrete pavers, and grid pavers. Review municipal regulations for permission to use pervious paving materials and consult with local officials and Soil Conservation Districts.<br />\nUsing pervious hardscape materials reduces:</p>\n<p>Decrease the rate and quantity of stormwater runoff<br />\nReduces pollution of total suspended solids and nutrients in the soil<br />\nEliminates the need for or reduces the size of detention ponds, protecting open space and wildlife habitats</p>\n<p>Three types of pervious pavement systems include pervious concrete, porous asphalt, and interlocking concrete pavers. Proper installation and base materials such as open-grade crushed stone maximize the surface’s ability to absorb and store water.[8]<br />\nMaintenance and Tips:</p>\n<p>Consider using salvaged bricks or recycled stone pavers<br />\nLook for a regionally-quarried stone to reduce transportation costs<br />\nPrevent clogging by cleaning any soil deposited on pavement and vacuum (as necessary) twice each year<br />\nMaintain planted areas adjacent to the pavement</p>\n<p> For additional information regarding the design of pervious pavement, see the NJ DEP Stormwater Best Practices Manual and the Green Infrastructure Guidance Manual for NJ.<br />\nRain Barrels and Cisterns<br />\nRain barrel and cistern systems collect, store, and distribute water for later use, providing a cost-effective and environmentally beneficial way to conserve water and minimize problems associated with stormwater runoff. Use rainwater collected in barrels and cisterns from catchment areas such as rooftops for irrigation, flushing toilets and other non-potable uses. Treat or filter the water depending on the intended use. Commercial applications often use cisterns or large-scale rain barrels.<br />\nStandard components of a rain harvesting system include[9]</p>\n<p>Catchment area such as a roof<br />\nGutters and downspouts<br />\nLeaf screens<br />\nRain barrel or cistern for storage<br />\nConveyance system to deliver stored water via gravity or pump<br />\nWater treatment or filter system</p>\n<p>Set aside sufficient space, either interior, above ground or underground, for the appropriately sized barrel or cistern. The size of rain barrels and cisterns varies from as small as 55-gallons to systems that hold thousands of gallons )which may require the use of an electric pump for distribution). To calculate the volume of water available for capture, assume that every 1,000 square feet of catchment area generates 600 gallons of runoff during a one-inch rainfall event.[10]<br />\nCatchment Area * Inches of Rain * 600 gallons *0 .75</p>\n<p>1,000 square feet<br />\nConsider combining rain barrels and cisterns with a drip irrigation system to direct overflow to a dry well, rain garden or bio-retention area.<br />\nRain barrels require maintenance. Use water within two weeks to prevent algae growth and clean barrels every few months. A screen with a cover prevents algae growth and mosquito breeding. Drain, disconnect and store rain barrels during the winter months.<br />\nFor more detailed information about the design and construction of rain barrels and cisterns see the Rutgers Water Resources Program’s – Green Infrastructure Manual for New Jersey.<br />\nRain Gardens<br />\nRain gardens, also referred to as vegetated swales and bioswales, consist of sloped depressions in the landscape planted densely with native plants that can soak up and filter stormwater runoff from rooftops, streets, or parking lots. Rain garden vegetation absorbs and filters stormwater before it enters storm drains.<br />\nPlace rain gardens to capture runoff from a site effectively. Observe the site during the next rain and note where runoff problems exist. Consider the following:</p>\n<p>Does it come from a roof or downspout?<br />\nIs there runoff from a parking lot?<br />\nDoes the runoff gravitate towards one place more than another?</p>\n<p>As a general rule of thumb, place the rain gardens at least 10 feet from building foundations if the structure has a basement; for buildings without basements, place rain gardens at least 2 feet from buildings.[11]<br />\nThe Rutgers NJ Agricultural Experiment Station’s Water Resources Program has installed over 125 demonstration rain gardens in New Jersey.<br />\nFor step-by-step guidance on installing a rain garden, see The Rutgers Water Resources Program and the Native Plant Society of New Jersey’s Rain Garden Manual of New Jersey.<br />\nVegetated Roofs<br />\nA vegetated roof or green roof consists of vegetation in a lightweight growing medium placed on top of the drainage layer, root barrier, and waterproof membrane (see Figure 1). Vegetated roofs provide many environmental benefits such as decreased stormwater runoff and reduced energy use. They absorb air pollutants and provide a habitat for beneficial insects and birds, serve as a sound barrier, and mitigate the urban heat island effect. Use a pre-engineered green roof system or customize the green roof to achieve a project’s specific performance objectives. Vegetated roofs often weigh between 10-50 pounds per square foot. Consult a structural engineer and evaluate the strength of the roof before installing a vegetated roof on a building. Consider reinforcing the roof to support the added weight.<br />\nThe two primary categories of vegetated roofs include: extensive and intensive. Extensive vegetated roofs consist of lightweight systems with shallow soil (or other growing media)  depths usually less than 6 inches.[12] Extensive vegetated roofs require less structural support than an intensive system and support a limited palette of hardy plants adapted to extreme environments that need little maintenance. Intensive vegetated roofs have deeper soil typically have more than 6″ of soil or other growing media, weigh more than extensive vegetated roofs, and can support a greater variety of plants. Intensive systems require more maintenance and a higher initial investment than an extensive roof.[13]<br />\nVegetated roofs can host a variety of plant species but typically include drought-tolerant species such as hardy succulents, sedums, and perennials. Consider low-maintenance, native species capable of living in the shallow soil. For a list of species indigenous to the Northeast, see NYC Greenbelt Native Plant Center or List of NJ Native Plants by County.<br />\nVegetated roof requires some maintenance such as watering during the establishment period and occasional weeding. Seasonal pruning and cutting of grasses and annual plants reduce the accumulation of combustible material on the roof. Regularly inspect and maintain the components of the roof’s drainage system such as gutters, underdrains, and downspouts.[14]<br />\nBlue roofs are systems designed to store and slowly release stormwater. Orifices, weirs, or other outlet devices manage and control the discharge rate of rooftop runoff, thereby reducing the size of downstream detention basins. Locations where the roof makes up a majority of the impervious surface area of the site, and where there is little room at the site for other stormwater management strategies make blue roofs most effective. </p>\n<p>For more information on blue roofs, see the NJ Stormwater Best Management Practices Manual – Chapter 9.8 Blue Roofs.<br />\n Water-Efficient Landscaping<br />\nDesign landscapes that rely on natural rainfall and only require supplemental irrigation during the plants’ initial establishment period. Use native and appropriate non-native vegetation adapted to site conditions and climate. Group plants with similar water requirements to maximize irrigation efficiency and use climate-based controllers for irrigation systems to lower water consumption. Collect non-potable water for irrigation from sources such as rooftops, greywater, air conditioner condensate, or stormwater basins.[15]<br />\nFor more information, refer to US EPA’s WaterSense Water-Smart Landscaping Design Guide.<br />\nExample of Site and Stormwater Management<br />\nSouthwest Park, Hoboken, NJ<br />\nA one-acre park designed with green infrastructure such as bioswales, rain gardens, permeable pavement, and underground chambers that can store 200,000 gallons of stormwater runoff, South Park in Hoboken NJ helps reduce localized flooding in the surrounding neighborhood.<br />\nBenefits<br />\nEffective stormwater management can;[16]</p>\n<p>Alleviate the rate and quantity of stormwater runoff, thus mitigates flooding.<br />\nProtect wetlands and aquatic ecosystems<br />\nImprove quality of receiving waterbodies<br />\nConserve water resources<br />\nProtect public health</p>\n<p>Costs<br />\nNatural areas lost to development and replaced with impervious surfaces require new and costly levees, pipes, and pollution-control technology to perform displaced ecosystem functions.<br />\nThe cost of site and stormwater management systems varies depending on the type of landscape and selection of strategies. For example, rain gardens vary in cost depending on the size of the roof and the selection of plants. According to the US EPA, estimated costs of installing a green roof average $10/sf for extensive roofing, and $25/sf for intensive roofs. Maintenance costs vary for either type of roof and may range from $0.75–$1.50/sf.[17] The typical cost for institutional rain gardens ranges from $30-$40 per square foot depending on existing soil conditions, the selection of plants, and whether or not the project requires professional installation, organizes volunteers, or uses in-house personnel.[18]<br />\nResiliency<br />\nGreen infrastructure integrates resilient and green design to complement and reduce reliance on traditional “grey” infrastructure.<br />\nIn coastal areas, tidal estuaries and along rivers, native and adapted plants act as an essential buffer to encroaching water during flood periods while acting as a routine defense against beach erosion.  For example, American Beachgrass considered one of the best lines of shoreline defense against storms and may also help prevent increasing levels of brackish water from infiltrating water tables close to a salt-water body.[19] In general, the root systems of native plants can reduce runoff and mitigate flooding.[20]  In the event of droughts, water-efficient landscapes designed with native and adapted plants add layers of protection against water scarcity. Rain gardens designed with native and adapted plants support ecological resilience by increasing the biological diversity of plants and animals in a given area, which in turn, enhances the ability of the natural system to rebound after a disturbance.<br />\nWhen massive storms, hurricanes, or droughts cause municipal water sources to shut down or pollute wells, rain barrels and cisterns can provide stockpiled water. Filter and purify before using the water to irrigate edible gardens, wash dishes, and or provide water for drinking and showering.<br />\nVegetated roofs can provide thermal insulation throughout all four seasons, reducing energy consumption and reliance on the electrical grid. In the event of a power outage, they can help keep temperatures cool in hot weather and warmer during the heating season. During heavy rainfalls and flooding events, vegetated roofs can help reduce stress on municipal stormwater infrastructure and reduce combined sewer overflows.[21] Vegetated roofs can also offer local communities the opportunity to grow some of their food, reducing dependency on supply chains and transportation networks often disrupted or compromised from storms and other events.<br />\n[1] US EPA National Pollutant Discharge Elimination System (NPDES) Stormwater Program https://www.epa.gov/npdes/npdes-stormwater-program (accessed April 2, 2018).<br />\n[2] NJ DEP.

Exfiltration refers to the loss of air from an enclosed space. While ventilation supports a healthy indoor environment, uncontrolled air infiltration can negatively alter airflow patterns, impacting mechanical systems, air quality, and thermal comfort.[2]  A Rutgers University study found a clear and significant correlation between the concentration of ultrafine particles (&lt;300 nm) inside a building and missing building insulation, indicating that particulate matter from outside can make its way into the building. Overall, particulate matter includes particles and droplets found in the air such as dust and dirt and smoke and can cause coughing, headaches and difficulty breathing and exacerbate existing health problems. [3] Ultrafine particles typically are emitted by combustion processes or can be created through chemical reactions of gasses.</p>\n<p>How to Manage Air Infiltration<br />\nMinimizing air infiltration starts with the design of the building envelope. A combination of insulation, moisture control, controlled ventilation, and air sealing contribute to the building’s thermal performance (see Exterior Wall Systems, Moisture Control, and Natural Ventilation).[4] Sealants, foams, improved insulation, tightly installed doors, and windows, and weather-stripping control air infiltration.[5] A continuous air barrier provides a system of interconnected materials, flexible sealed joints, and building envelope components that provide an airtight separation between conditioned and unconditioned spaces.[6]<br />\nThe PFT (perfluorocarbon tracer gas) technique and blower door test are two standard methods for determining air-tightness that then helps prevent energy loss in a building. A blower door test locates air infiltration by exaggerating the defects in the building shell, measuring air infiltration at a specific point in time. The PFT technique measures air-infiltration over time (e.g., decay in tracer gas concentration over time), finding overall problems rather than exact points of infiltration.[7]<br />\nMany green building guidelines encourage building with a very tight envelope that provides ventilation in a controlled, reliable way to increase energy efficiency and comfort. For example, the Passive House Institute US Certification Program (also applicable to commercial buildings) requires airtight building construction and the following passive design building-science principles:[8]</p>\n<p>Continuous insulation throughout the building envelope without thermal bridging.<br />\nAn airtight building envelope prevents infiltration of outside air and loss of conditioned air from inside.<br />\nWell installed high-performance windows (typically triple-paned) and doors.<br />\nBalanced heat- and moisture-recovery ventilation and minimal space conditioning system.<br />\nPassive solar strategies for heating and reduced solar gains during the cooling season.</p>\n<p>Example<br />\nRocky Mountain Institute (RMI) Innovation Center, Basalt, Colorado.<br />\nThe RMI Innovation Center achieved Passive House US+ Certification and demonstrated airtight building construction. The building’s recorded air leakage value, 0.36 air changes per hour (ACH) at one pound per square foot pressure (ACH@50 Pa), means that the total area of cracks, gaps, and holes in the entire building envelope equals 61 square inches, about the size of a basketball.[9] A typical older office building has an equivalent hole 24 times larger, or 12 ft2.[10]<br />\nBenefits<br />\nAirtight building construction improves energy efficiency, indoor air quality, and thermal comfort. Reducing air infiltration lowers utility bills, reduces the influx of unconditioned air and the loss of conditioned air, and reduces the amount of energy spent on creating comfortable thermal conditions (see Properly-Sized, High-Performance HVAC Equipment and Controls).[11]<br />\nCosts<br />\nContinuous air barrier systems can reduce air leakage by up to 83%, gas savings over 40%, and electrical savings over 25%.[12] Overall cost considerations for managing air infiltration should include the potential savings of reduced energy loss and proper HVAC sizing.<br />\nResiliency<br />\nReducing air infiltration provides several resiliency benefits. By reducing leaks and drafts and helping to maintain thermal comfort and indoor air quality, an airtight building insulates building occupants during a power outage and can protect them from unwanted air pollutants, contaminants, and airborne security threats (e.g., chemical and biological agents). Reducing air infiltration drives down a building’s peak heating and cooling demand, reducing stress on the grid. Preventing unwanted air leakage in a building can also enhance building resiliency and durability by reducing the flow of condensation inside the envelope, which in turn can cause rot.[13]<br />\n&nbsp;<br />\n[1] Whole Building Design Guide (WBDG).

A daylighting-optimized building maximizes south and north exposures and minimizes east and west exposures. Low sun angles make it more difficult to shade and to avoid glare and heat gain from east and west facing windows compared to south and north facing windows that receive more favorable sources of direct and indirect natural light, respectively.[1] The design and choice of window glazing also affect the amount, distribution, and quality of daylight.[2] For example, glazing systems with tinted glass and low-solar low-E coatings reduce solar heat gain with little reduction in visible transmittance or the amount of light in the visible portion of the spectrum.[3] Introducing daylight from skylights or solar tubes can also help balance daylight in a room. Utilize the upper portion of windows to introduce high levels of daylight and avoid glare issues, while taking advantage of views from the lower portion of windows, balanced by proper shading.[4] Exterior shading and control devices such as light shelves, overhangs, louvers, and reflecting systems and self-shading elements of building form such as wings and deep-set windows can reduce heat gains, soften harsh light contrasts, and diffuse natural light. Interior designs that incorporate open layouts and light-colored surfaces also bounce light throughout interior spaces. For example, dark interior finishes can compromise an otherwise successful daylighting design.[5] Furniture, cubicles, and workstations can block light and have a substantial impact on the light levels in a given space. Model any partition systems or permanent furniture in the design phase as they can have a significant impact on interior light levels.[6] Reduce electrical lighting consumption and costs, and associated waste heat by pairing harvested daylight with automated dimmers and photosensors (see High-Efficiency Lighting Systems and Networked Lighting Controls).</p>\n<p>How to Implement Daylighting<br />\nDesigning for daylighting in existing buildings involves complex interactions among multiple building systems and disciplines, requiring an integrated design process. Renovations provide an opportunity to assess current daylight levels and identify opportunities for improvement.</p>\n<p>The first step to a daylighting and lighting upgrade is to conduct a lighting audit or survey that establishes information about all the lighting technologies and consumption patterns in a building.  Use Energy Star Portfolio Manager to benchmark energy usage and identify lighting upgrade opportunities.</p>\n<p>The following steps outline strategies to integrate daylighting and electrical lighting into lighting upgrade projects.[7]</p>\n<p>	Set a Maximum Lighting Power Density (LPD) goal to avoid overlit spaces and to achieve an appropriate level of lighting per area lit or watts per square foot.<br />\n	Set a Daylight Sufficiency Goal that establishes the amount of daylighting, measured in lumens or foot-candles, required to perform a typical task in each space without electrical lighting.<br />\n	Develop a layered lighting strategy that first utilizes daylight to provide basic or ambient lighting levels, and then adds electrical lighting options and controls to vary lighting levels for a variety of tasks and occupant preferences.</p>\n<p>While daylighting strategies, such as maximizing southern building orientation, may not be technically or financially feasible for a renovation project, many daylighting strategies are available for existing buildings, including:[8]</p>\n<p>	Opening the building perimeter to office space.<br />\n	Transferring light through perimeter spaces through lower partitions or by replacing opaque panels with transparent or translucent panels.[9]<br />\n	Exposing closed-off overhead glazing.<br />\n	Creating light shelves for high spaces.<br />\n	Adding skylights, clerestories, atria, or roof monitors.<br />\n	Improving reflectance values for ceiling tiles, walls, and carpet.[10]</p>\n<p>Daylighting guidelines provide general principles and examples, but project specific solutions often require hiring a daylighting expert familiar with advanced computer simulation software and tools, which can effectively simulate a range of scenarios and outcomes.[11]</p>\n<p>The Facade Design Tool by the Efficient Windows Collaborative compares several design parameters including orientation, window area, controls, shading, and window type to predict performance outcomes such as annual energy use and savings, daylight levels, glare, and thermal comfort.</p>\n<p>Low Energy – High Performance:  Building Façade Solutions by Berkeley Lab offers a list of simulation software for modeling window system performance.</p>\n<p>For daylighting strategies specific to existing commercial projects, see Guide 5 of the Philadelphia High-Performance Building Renovation Guidelines.<br />\nExamples<br />\nAtrium II, Secaucus, NJ </p>\n<p>Renovations to Atrium II, a 260,000 square foot office building in Secaucus, NJ, included improved daylighting through upgrades to the building envelope and the installation of lighting controls such as timers, photocells, and motion sensors.</p>\n<p>Perimeter Office Zones, Washington, DC</p>\n<p>This case study and design guide examine the best combination of window area, shading device and glazing type to save energy.<br />\nBenefits<br />\nControlled, natural lighting can lead to many improvements:</p>\n<p>	Reduced operating costs through reductions in electrical lighting usage.[12]<br />\n	Reduced cooling loads and downsized HVAC systems through less heat gain from electrical lighting (see Properly-Sized, High-Efficiency HVAC and Controls).[13]<br />\n	Improved employee productivity and satisfaction based on a shared preference for naturally daylit spaces, reinforcement of circadian rhythms, and connection to nature.[14]<br />\n	Above average lease rates and lower tenant turnover.[15]</p>\n<p>Costs<br />\nThe cost associated with integrating daylighting strategies into an existing building varies depending on the scope of the project. The design and material selected for interior or exterior shading and solar control devices, for example, impacts the cost. There is a range of options available from very low-cost solutions such as rearranging the layout of a room to a more comprehensive approach of adding integrated lighting controls and shading devices. The costs of hiring an expert daylighting consultant and electrical lighting designer often pay for themselves through electrical lighting reductions and associated energy cost savings.<br />\nResiliency<br />\nIn the event of a power outage, a daylighting-optimized building continues to provide interior light to building occupants, while at the same time reducing reliance and stress on the grid and providing energy savings.</p>\n<p>[1] Lawrence Berkeley Laboratory and US DOE. 2013.

Upgrading exterior walls provides the opportunity to fix structural or cosmetic damages, control moisture, improve insulation, and increase daylighting. Common wall system upgrades include:</p>\n<p>Adding insulation<br />\nAir sealing doors and windows<br />\nRepairing holes, cracks and gaps<br />\nUpgrading windows and glazing</p>\n<p>The building envelope or the physical structure between the inside of the building and the outside environment includes walls, windows, doors, roof systems, and the foundation.[1] Exterior wall systems often comprise the majority of the building envelope, playing a pivotal role in determining levels of comfort, natural lighting and ventilation, and the energy required to heat and cool a building.[2]<br />\nBuilding R-values assess a wall’s thermal resistance. The higher the R-value, the better the building in reducing heat loss.[3] Air leakage contributes to 25- 40% of a building’s heat loss (see Air Infiltration).[4] Maintaining and investing in well-insulated (high R-value rating) walls/wall systems yields energy savings.<br />\nThe following includes examples of insulation materials and wall systems:[5]</p>\n<p>Continuous and Cavity Insulation. Continuous insulation runs uninterrupted over structural membranes, avoids thermal bridging and is installed on the exterior surface of the building envelope.[6] Cavity insulation is installed between structural components such as wood studs.<br />\nComposite Metal Panels consist of two sheets of metal adhered to a core material and include:[7]</p>\n<p>Foamed-Insulation Core Metal Wall Panels<br />\nLaminated-Insulation Core Metal Wall Panels<br />\nHoneycomb Core Metal Wall Panels</p>\n<p>Exterior Insulation Finish Systems (EIFs) consists of exterior wall cladding made of rigid insulation boards. The polymer-based (PB) system is most popular and consists of closed expanded polystyrene (EPS) insulation finished with a polymeric (organic) bonded aggregate and cement reinforced with a glass mesh.[8] Being lightweight and low cost, and the ability to achieve different aesthetic effects make EIFs a popular choice.[9]<br />\nInsulated Concrete Forms (ICFs) consists of concrete walls poured inside foam insulation forms with steel reinforcing and stacked as interlocking blocks.[10] Insulated concrete block or concrete masonry units (CMUs) form prefabricated blocks applied like traditional block wall construction.<br />\nStructural Insulated Panels (SIPs) consist of an insulating foam core placed between two structural panels, typically oriented strand board (OSB) or fiber cement panels.[11]<br />\nVacuum Insulated Panels (VIPs) consist of an interior, solid layer of a high R-value material wrapped in an exterior layer of airtight foil with a vacuum drawn inside the airtight foil.[12] They can achieve an R-value of 50 without adding bulk, making them cost-effective on roofs.[13]</p>\n<p>How to Upgrade Exterior Wall Systems<br />\nAssess the building’s existing insulation and daylighting levels. Consider hiring a building envelope contractor experienced in air sealing and insulation. Perform an energy audit including a blower door test to measures the airtightness of the building and identify problem areas. Hire a daylighting professional to identify cost-effective opportunities to improve daylighting (see Daylighting and Windows and Skylights).<br />\nThe US DOE recommends reducing envelope leakage and minimizing air infiltration by sealing, caulking and placing weather-strip to the following areas:[14]</p>\n<p>Joints around fenestration and door frames.<br />\nJunctions between walls and foundations, between walls at building corners, between walls and structural floors or roofs, and between walls and roof or wall panels.<br />\nOpenings at penetrations of utility services through roofs, walls, and floors.<br />\nSite-built fenestration and doors.<br />\nBuilding assemblies used as ducts or plenums.<br />\nJoints, seams, and penetrations of vapor retarders.<br />\nAll other openings in the building envelope.</p>\n<p>Re-caulking and weather stripping windows and doors provide a low-cost option for upgrading the exterior wall system by minimizing air leakage. Poorly sealed buildings lack humidity control, contributing to moisture damage and mold growth that damages building materials and impacts the structural integrity of the building. Airtight buildings improve the effectiveness of insulation. Balancing airtightness with controlled ventilation helps to supply the appropriate level of fresh air into the building.<br />\nExample<br />\nPassive House Institute, US strategies applicable to commercial building retrofits, include:</p>\n<p>A combination of internal and external insulation to reduce thermal bridging<br />\nWhole building air barriers, with commissioning before occupancy<br />\nMoisture management in enclosure assemblies<br />\n“Cool walls” that have optimum reflectivity and ventilation against solar gain</p>\n<p>Benefits<br />\nA properly designed exterior wall system offers the following benefits.[15]</p>\n<p>Reduces energy costs<br />\nPrevents moisture condensation<br />\nReduces capacity and size of new mechanical equipment<br />\nReduces noise levels<br />\nIncreases indoor environmental quality and thermal comfort.[16]<br />\nProvides fire protection</p>\n<p>Costs<br />\nThe cost of adding insulation, air sealing doors and windows, and filling gaps and holes vary based on the conditions and scope of the project. There are often incentives available for upgrading exterior wall systems. See the New Jersey Office of Clean Energyfor available incentives and financing programs.<br />\nResiliency<br />\nExpertly designed and installed exterior wall systems offer several essential resiliency benefits. In the event of a power outage, well-insulated buildings protect against heat loss in the winter and heat gain in the summer, helping to maintain comfortable internal temperatures for building occupants, and reducing stress on the grid. A daylighting-optimized building continues to provide interior light to building occupants when the power goes out. Wall assembly systems (with insulating properties) such as precast concrete panels, insulated concrete forms (ICFs), and structural insulated panels (SIPs) offer resistance to hazards such as fire, wind, earthquakes, and floods, and improve indoor environmental quality through resistance to mold.[17]<br />\n&nbsp;<br />\n[1] Arnold, Chris. 2016. “Building Envelop Design Guide.” Whole Building Design Guide (WBDG).

For example, sun glare on a document makes the black text almost as bright as the white background, reducing the contrast and making the document difficult to read.</p>\n<p>Heat gain describes when solar radiation or warmth enters a building through windows, skylights or other glazing systems. Maximizing heat gain during the winter through passive solar strategies and minimizing heat gain and reducing cooling loads during the summer, while maintaining daylighting quality, provides energy and cost savings and enhances thermal comfort (see Daylighting).</p>\n<p>Reducing glare and heat gain requires balancing electrical lighting and daylighting goals and utilizing protective barriers such as high-performance window glazing systems and external or internal physical barriers such as shades, blinds, awnings, overhangs or vegetation (see High-Efficiency Lighting Systems, Energy-Efficient Windows, and Energy-Efficient Landscaping).</p>\n<p>How to Implement Glare and Heat Gain Reduction<br />\nDesigning for glare and heat gain reduction in existing commercial building involves complex interactions among multiple building systems and disciplines, requiring an integrated design process (see Integrated Design Process). Renovations provide an opportunity to assess current glare and heat gain issues and to identify opportunities for improvement.</p>\n<p>The first step is to conduct an energy audit to identify cost-effective strategies to reduce energy consumption and improve thermal comfort in glare and heat reduction categories such as daylighting and lighting, window replacement, and building envelope upgrades (see Energy Audit). Use Energy Star Portfolio Manager to benchmark energy usage and identify upgrade opportunities.</p>\n<p>Project-specific solutions often require hiring a daylighting or lighting expert familiar with advanced computer simulation software and tools that can effectively simulate a range of scenarios and outcomes.[1]</p>\n<p>Use simulation programs such as the Efficient Windows Collaborative Window Selection Tool or Berkeley Lab’s RESFEN to determine energy-efficient and cost-effective window options. Look for the ENERGY STAR label, which sets standards for energy-efficiency that often exceed local energy code requirements.[2]</p>\n<p>The following strategies and information provide general guidance on reducing glare and heat gain in existing buildings:</p>\n<p>The Solar Heat Gain Coefficient (SHGC) indicates how much of the sun’s solar energy transmits through the window as heat. As the SHGC increases, the solar gain potential increases. Visible transmittance (VT) refers to the amount of visible light transmitted through the window. A higher VT means more daylight in a space. Advances in high-performance tinted glass and low-solar-gain low-e coatings reduce solar heat gain while maintaining visible transmittance. Using high-performance windows to provide solar control reduces the need for operating shades, resulting in increased daylight and unobstructed views.</p>\n<p>When selecting a window based on performance, look for visible transmittance (VT) levels higher than (&gt; 70%), especially for daylighting applications (see Daylighting).[3] For New Jersey’s Northern/Central climate zone, EnergyStar recommends SHGC of 0.4 (40%) or lower for buildings with moderate air conditioning requirements. Look for SHGC values of 0.25 or less for buildings with significant air conditioning costs or summer overheating problems.[4] For New Jersey’s Northern/Central climate zone, a U-factor of &lt; 0.25 is recommended for high-performance buildings.[5]</p>\n<p>Managing solar heat gains on the exterior of the building prevents heat from entering the building in the first place. In combination with high-performance glazing systems, consider shading devices early in the design process to achieve a well-integrated architectural design.</p>\n<p>Exterior shading and control devices such as light shelves, overhangs, louvers, and reflecting systems and self-shading elements of building form such as wings and deep-set windows can reduce heat gains, soften harsh light contrasts, and diffuse natural light.</p>\n<p>Interior glare control devices, such as Venetian blinds, miniblinds, vertical<br />\nslatted blinds, pleated and honeycomb shades, and roll-down shades can reduce direct sunlight and glare but are less effective at reducing cooling loads since they only block sunlight and do not prevent solar gains from entering the building.[6] Motorized and automated shading systems use sensors, time clocks, a building automation system or occupant control to adjust the position of window coverings to reduce glare, daylighting or privacy levels or heat gain (see Smart Sensors and Controls).</p>\n<p>Natural landscaping such as mature trees or hedgerows can provide shading. Plant a shade tree near the window or skylight to shade it during the summer months and let as much light and heat in as possible during the winter months (see Energy-Efficient Landscaping).<br />\nExamples<br />\nSmith Middle School Chapel Hill, NC.</p>\n<p>This case study documents that proper daylighting design that addresses glare and heat gain reductions can result in energy savings (64% reduction in lighting energy), occupant comfort (teachers and students favor daylighting in the classrooms) and return on investment (4.2 years).</p>\n<p>Perimeter Office Zones, Washington, DC.</p>\n<p>This case study and design guide examine the best combination of window area, shading device and glazing type to save energy.<br />\nBenefits<br />\nEffectively managing glare and heat gains offers multiple benefits, including:</p>\n<p>	Reduced peak heat gain and cooling requirements in the summer and maximized solar heat gain in winter, leading to mechanical equipment downsizing, saving capital costs, and reducing mechanical loads and operating expenses (see Properly-Sized HVAC Equipment).[7]<br />\n	Improved daylighting design, reducing electrical lighting requirements.<br />\n	Diminished ultraviolet (UV) and other solar radiation which causes fading of fabrics and furnishings.<br />\n	Added environmental benefits such as stormwater management and occupant benefits including views and connection to nature by utilizing energy-efficient landscaping.<br />\n	Increased occupant visual and thermal comfort by managing glare and solar heat gains resulting in increased occupant satisfaction and productivity.[8]<br />\n	Enhanced visual interest in building design through the use of shading devices, building orientation and architectural form.</p>\n<p>Costs<br />\nCosts vary depending on the types of strategies implemented. Designing for glare and heat gain reduction should not impose a significant impact to project costs if considered early in the design phase and integrated throughout the design process. The costs of hiring an expert daylighting consultant and electrical lighting designer often pay for themselves through electrical lighting reductions and associated energy cost savings.</p>\n<p>The cost of windows varies by project. Energy savings combined with improved visual and thermal comfort and daylighting benefits often justify the investment in high-performance windows. Available rebates and incentives can help offset upfront costs. For up-to-date information on available incentives, visit the ENERGY STAR and the NJ Clean Energy Program websites.</p>\n<p>The cost of planting a tree or shrub for shade may range from as little as $10 to hundreds of dollars depending on materials and labor and maturity of selected landscaping vegetation.[9]</p>\n<p>External window coverings range in price from low-budget options for an aluminum awning to more costly investments for a shade structure. There are also additional costs associated with maintenance of outdoor structures, notably year-round or permanently affixed shades.<br />\nResiliency<br />\nIn the event of a power outage or a heat wave during the summer months, a building designed to optimize daylighting and reduce glare and heat gain can maintain comfortable internal temperatures and lighting levels for building occupants, while at the same time reducing reliance and stress on the grid by reducing the need for electrical lighting and air conditioning.</p>\n<p>&nbsp;</p>\n<p>[1] WBDG.

Most roofs last 20-25 years, providing multiple opportunities over the life of the building to reevaluate roofing options as well to as assess a roof’s impact on the building’s energy and environmental performance. Opportunities include evaluating thermal performance, systems integration, rooftop HVAC upgrades, water management (storm runoff capture), indoor environmental quality, and the impact of the roofing material on the environment.[1] For example, improving roof insulation can reduce heating and cooling needs, allowing for the downsizing of HVAC equipment, and further energy savings (see Insulation and Properly Sized HVAC Equipment). Selecting roofing materials with a high Solar Reflectance Index (SRI) reduces cooling loads, mitigates the urban heat island effect, and extends the life of the roof and rooftop mechanical equipment (see Cool Roofs). Incorporating skylights or solar tubes into a roof replacement or upgrade improves daylighting (see Daylighting). Green or vegetated roofs and rooftop cisterns provide stormwater management benefits (see Site and Stormwater Management). Replacing or upgrading a roof also provides the opportunity to consider on-site renewable energy systems and thermal energy storage. (See On-Site Renewable Energy Systems and Thermal Energy Storage). Non-toxic roofing materials with recycled content (e.g., cool metal roof) are available that are durable, low maintenance, and recyclable at the end of their useful life.[2] Other advances in roofing technology include integrated data systems, such as drones that take infrared scans and provide alerts of water or moisture build-up on the roof or that provide pictures necessary for job estimates and simplify and improve roof installation and maintenance.[3]<br />\nThere are two main types of roofs: low-sloped and steep-sloped (the majority of commercial buildings have low-sloped roofs). The following lists roofing coverings for low-slope and steep-slope roofs.[4]</p>\n<p>How to Implement Roof Replacements and Upgrades<br />\nAutomatically selecting a replacement or upgrade similar to the existing roof fails to recognize changes that affect roof and building performance such as the addition over time of new mechanical equipment, changing weather patterns, or unanticipated rooftop uses. When implementing a roof replacement or upgrades, consider roofing strategies that offer multiple benefits.<br />\nMany building codes and green building programs have a cool roof and urban heat island mitigation requirements that refer to ENERGY STAR and the Cool Roof Rating Council (CRRC) voluntary roof labeling programs (see Cool Roofs). Converting an existing roof into a cool roof involves either retrofitting the roof with heat-reflective coatings or materials, re-covering the roof with a new waterproofing surface or entirely replacing the roof with a new cool roof.[7]<br />\nExamples<br />\nState of the Art in Enclosure Technologies and Integrated Systems for 50% Energy Savings in Existing Commercial Buildings.<br />\nThe One-Factor-At-a-Time (OTA) Evaluation of Building Enclosure Measures Study demonstrated a 19.8% reduction in heating energy and a 17.1% reduction in total energy by installing R30 roof insulation cool roofing material with a high Solar Reflectance Index (SRI).[8]<br />\nUS Post Office and Courthouse, Camden, NJ<br />\nThis retrofit roofing project, sponsored by the General Service Administration (GSA) Green Proving Ground (GPG) program, installed Vacuum Insulated Panels (VIPs) at the U.S. Post Office and Courthouse in Camden, New Jersey. VIPs consist of a solid interior layer of a high R-value material wrapped in an exterior layer of airtight foil with a vacuum drawn inside the airtight foil.[9] The study used energy modeling and thermographic images and found that VIPs can offer a favorable payback in one-story buildings in regions with extreme climates and high utility costs.[10] They can achieve an R-value of 50 without adding bulk, making them cost-effective on roofs.[11]<br />\nSolar Panel System added to Distribution Facility in Edison, NJ.<br />\nWith funding from the PSE&amp;G Solar Loan Program, Avidan Management installed a 4.26-megawatt photovoltaic system in Edison, New Jersey, which produces 5 million kilowatt hours of power a year, about half of the power needs of the facility’s seventeen commercial tenants.[12]<br />\nThe Geraldine R. Dodge Foundation Green Roof, Morristown, NJ.<br />\nThe Foundation’s 2,000 square foot vegetated roof, planted with native plant species, provides a home for many bird and butterfly species and absorbs 90% of rainfall.[13]<br />\nBenefits<br />\nRoof improvement projects offer several potential benefits, including.</p>\n<p>Energy cost savings by reducing cooling loads.[14]<br />\nLowered peak electricity demand which decreases the likelihood of power outages.[15]<br />\nReduced roof temperatures which may reduce roof maintenance and replacement expenses by extending roof life.[16]<br />\nIncreased indoor thermal comfort in summer, helping to prevent heat-related illness and deaths.[17]<br />\nMitigated heat island effect in cities and suburbs.[18]<br />\nReduced air pollution and smog formation.<br />\nWater reduction savings for urban irrigation.[19]<br />\nMinimized heat loss in winter in cold climates when combined with appropriate insulation levels.[20]</p>\n<p>Costs<br />\nThe cost of a roof replacement or upgrade varies depending on the type of roof improvement and scope of the project. Preventative maintenance and regular roof inspections help to save costs through early detection and avoided or reduced repair costs. Replacing the roof before it fails saves money by preventing extensive damage to the building interior. Prescheduling also allows time for evaluating roofing options, preparing specifications, and selecting a qualified and cost-competitive installer.<br />\nA roof’s life-cycle costs include upfront installation (materials and labor) and ongoing savings and maintenance costs (repair, recoating, and cleaning). The installed costs vary depending on the type and size of the roof, complexity of the roof system, and building location. For example, in cases where new roof surfaces need to be installed, adding a cool roof coating to a new roof cost about the same as adding a conventional dark roof with the cost premium ranging from $0.00 to $1.90/SF over conventional roofing products.[21] Energy costs savings provide for a relatively short-term (1 year or less) payback.[22]<br />\nFor a list of price premiums for cool roof upgrades, see the Global Cool Cities Alliance’s Cool Roof and Pavements Toolkit. The City of New York Department of Design and Construction Cool &amp; Green Roofing Manual also provides a cost analysis of green and cool roof upgrades. For up-to-date information on available incentives, please visit the New Jersey Clean Energy Program.<br />\nResiliency<br />\nWell designed, correctly installed, and routinely maintained roofs contribute to resiliency by providing a durable roofing material and through energy efficiency.  For example, cool roofs enhance roofing durability by reducing thermal flux and increasing the roof’s resiliency to changing climate conditions, heat and UV aging.  Cool roofs also contribute to decreased air-conditioning loads, thereby extending the life of AC units. Regarding energy efficiency, adequately insulated roofs, can reduce heating and cooling loads, reducing stress on the grid, and help to regulate thermal comfort in the event of a power outage. In addition to stormwater management benefits, such as reduced flooding, vegetated roofs can offer the opportunity for local communities to grow food, reducing the dependency on supply chains and transportation networks often disrupted or compromised due to storms and other events.<br />\n <br />\n[1] Vivian Loftness et al.

The fenestration system, or arrangement of openings in a building envelope, determines a building’s HVAC requirements and daylighting.[1] Appropriately placed and selected energy-efficient or high-performance windows maximize natural light and minimize glare and heat gain or loss, decreasing dependence on electric lighting and HVAC systems and improving thermal comfort, energy-efficiency, and daylighting (see Daylighting and Glare and Heat Gain Reduction).[2] Advanced window technologies such as chromogenic windows and auto-operated windows and shading devices offer daylighting, solar heat gain control and ventilation benefits. Two types of chromogenic windows include thermochromic, which uses adhesive coating to adjust tinting passively with window surface temperature; and electrochromic, which use operable switches or automated building control systems to tint the window via electric current.[3] Operable windows and shading systems use auto-controlled devices that open and close at specific times of the day to manage ventilation levels or light levels and control indoor temperatures and manage solar heat gain.[4]<br />\nHigh-performance window technologies including low emissive or low-e glass panes, spacers, and insulated frames help prevent energy loss due to conduction, radiation, convection, and air leakage (see Air Infiltration). Low-e windows, treated with a microscopically thin coating, reduce heat flow. Spacers or tiny pieces placed between panes in double- or triple- paned windows, create an insulated space often filled with an inert gas such as argon or krypton to increase the window’s insulation properties (see Exterior Wall Systems).<br />\nState and local energy codes, federal tax credits, and utility incentives, and ENERGY STAR base their criteria for energy-efficient windows on certified ratings by the National Fenestration Rating Council (NFRC). NFRC labels provide ratings for U-factor, Solar Heat Gain Coefficient (SHGC), Visible Light Transmittance (VT), and optionally Air Leakage (AL) and Condensation Resistance (CR) ratings.<br />\nA window’s U-factor describes its rate of heat transfer or insulating properties. A lower U-factor indicates a window with higher resistance to heat flow, or a better-insulated window.[5] The Solar Heat Gain Coefficient (SHGC) indicates how much of the sun’s solar energy transmits through the window as heat. As the SHGC increases, the solar gain potential increases. Visible transmittance (VT) refers to the amount of visible light transmitted through the window. A higher VT means more daylight in a space. Advances in high-performance tinted glass and low-solar-gain low-e coatings reduce solar heat gain while maintaining visible transmittance. The Air Leakage (AL) rating describes leakage through cracks in the window assembly. Condensation Resistance (CR) rates windows on a range between 1 and 100 with higher numbers signaling increased resistance to condensation.<br />\nHow to implement window and skylight upgrades<br />\nFirst, conduct an energy audit to identify sources of air infiltration and to determine opportunities to improve energy-efficiency. Consider improvements to windows and skylights (and the entire fenestration system) early in the renovation process and integrate with updates to other building systems. For example, increasing roof insulation and wall systems in combination with window system upgrades offer a significant opportunity for energy savings.  A retrofit of the windows and skylights also offers the opportunity to improve natural light and introduce complementary systems such as daylighting sensors. Use simulation programs such as the Efficient Windows Collaborative Window Selection Tool or Berkeley Lab’s RESFEN to determine energy-efficient and cost-effective window options. Look for the ENERGY STAR label, which sets standards for energy-efficiency that often exceed local energy code requirements.[6]<br />\nImprovements to consider when upgrading windows and frames include:[7]</p>\n<p>Double or triple-paned glass<br />\nInert gas fill (e.g., krypton, argon, or nitrogen)<br />\nLow-e, glass or film and other advanced coatings and films<br />\nWindow tinting appropriate for the climate and building orientation<br />\nInsulated frames, low-conductivity materials<br />\nChromogenic windows that can reduce HVAC and lighting energy use by controlling heat transfer and daylight transmittance in real time.</p>\n<p>Window performance depends on proper installation, sealing and flashing to prevent air leakage and water damage. Window manufacturers often provide detailed installation requirements and specifications for their products and may have recommendations for in-house installers and programs, 3rd party installers, or installer certification programs such as Installation Masters™. ASTM Standard E 2112 provides a nationally recognized standard for proper window installation.<br />\nBenefits<br />\nEnergy-efficient windows contribute to the satisfaction, health, and productivity of building occupants by providing daylighting, reducing glare, providing views of nature, and regulating thermal comfort. By providing natural light, managing glare, and eliminating the need for window treatments that completely block out sunlight, high-performance windows can reduce electric lighting loads while at the same time reducing the ultraviolet (UV) and other solar radiation which causes fading of fabrics and furnishings. Energy-efficient windows designed as part of an overall energy management strategy can lead to mechanical equipment downsizing, saving capital costs, and reducing mechanical loads and operating expenses (see Properly-Sized HVAC System).<br />\nCosts<br />\nThe cost of window and skylight upgrades varies by project. Energy savings combined with improved thermal comfort, daylighting, and enhanced security benefits often justify fenestration upgrades. Smaller HVAC systems and annual energy savings can offset the cost of upgrading to high-performance windows and skylights when combined with wall upgrades. Energy savings alone can justify upgrading the glazing to soft coat double-pane, and low-e.  Better glazings can result in higher energy savings in connection with daylighting systems. Commercial buildings with adequately specified fenestration systems have the potential to reduce lighting and HVAC costs 10%–40%.[8] Maintenance and repair have a significant impact on the life-cycle cost of windows and skylights. Glass, a highly durable material only needs replacement when broken. Window frame durability depends upon maintenance. Framing materials typically have a useful life of 20 to 50 years depending upon the type of deterioration such as rot and corrosion.  Sealants, caulks, tapes, and other glazing materials used to achieve weather-tightness typically have a useful life of 15 to 30 years depending upon thermal stress, movement, and environmental exposure.[9] Driven by the demand for large TV screens and recent improvements in thin glass technology, the cost of sub-millimeter glass compares to standard, double-strength glass.[10]<br />\nFor up-to-date information on available incentives, visit the ENERGY STAR and the NJ Clean Energy Program websites.<br />\nResiliency<br />\nIn the event of a power outage, a building with energy-efficient windows maintains comfortable internal temperature for building occupants by reducing heat gain and reducing cooling loads during the summer months. During the winter months, energy-efficient windows provide better insulating properties compared to conventional windows while also offering daylighting, passive solar heating, and enhanced thermal comfort in the case of a power outage. Energy-efficient windows reduce reliance and stress on the grid and provide energy savings. In areas prone to flooding, wind-driven rain, snow storms or hurricanes, properly sealed and flashed windows protect against problems caused by water intrusion, including mold, warping, and structural damage.<br />\n&nbsp;<br />\n[1] Whole Building Design Guide (WBDG) – Windows and Glazing http://www.wbdg.org/resources/windows.php (accessed April 10, 2018).<br />\n[2] Efficient Windows Collaborative.

Properly insulating a new home relates to creating an efficient building envelope. A properly insulated building envelope increases the efficiency of the heating, ventilation, and air-conditioning (HVAC) system, reducing energy costs while increasing occupant thermal comfort by acting as a thermal barrier and controlling indoor temperature and humidity levels. For example, in cold and damp basements, adequately insulated foundation walls and floor slabs reduce heating and cooling costs and result in more comfortable below-grade rooms. Insulation also helps prevent problems with moisture, insects, and radon in the home (see Radon Mitigation System strategy). It is important to note that insulation only helps reduce air and heat flow in the space where it is contained. Therefore it is most effective when the home is also correctly sealed against excess air infiltration (See Air Infiltration Reduction).[1] Other components of the typical building envelope include windows, doors, walls, roof, and foundation, all of which require different types of insulation.</p></div>\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_6  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_7  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				<div class=\"et_pb_text_inner\">How to Insulate<br />\nA highly insulated building envelope requires an integrated design approach during the pre-design phase of a new home project that views the building as a whole system and coordinates the insulation of all the building elements (see Integrated Design Process). Consider the selection of materials used in the walls, doors, roof, windows and foundation, as well as daylighting strategies, the design of HVAC and electrical systems, and the home’s energy performance goals. For example, a highly insulated building envelope reduces the energy requirements and therefore the size of the home’s HVAC system by minimizing the loss of conditioned air to the outside (see Properly Sized HVAC Equipment).<br />\nInsulation ratings refer to R-value or resistance to heat flow. [2] An insulation’s material composition and thickness contribute to its R-value. A higher R-value indicates higher expected thermal performance. However, more is not always better, as there is a point of diminishing returns with insulation (i.e., the intersection between cost and energy savings).[3] Look for Energy Star certified insulation tested for performance and safety standards. Compare the R-value of the selected insulation to local and state building code requirements and best practice recommendations for the local climate region. The International Energy Conservation Code (IECC) Compliance Guide for Homes in New Jersey provides detailed information about the different climate zones in New Jersey and corresponding insulation standards.[4]<br />\nWhile fiberglass batt insulation remains popular, a growing number of other insulation options exist (see Table 1). For example, insulated concrete forms (ICFs), insulated pre-cast concrete wall systems and structural insulated panels (SIPs), provide structural support with built-in insulation.</div>\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_8  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_9  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				<div class=\"et_pb_text_inner\">Proper installation impacts the R-value of insulation. Homeowners can install some types of insulation, such as batts and rolls, but other types may require professional installation.[5] The US DOE offers the following guidelines when hiring an experienced installer:[6]</p>\n<p>Obtain written cost estimates based on R-value from several contractors.<br />\nAsk contractors about air-sealing services and costs.</p>\n<p>For more information on the different types of insulation and on hiring a professional installer, see the US DOE: Energy Savers – Types of Insulation and Energy Star websites.<br />\nExamples<br />\nBASF Near-Zero Energy Home, Paterson, NJ<br />\nBASF, a chemical company, constructed a near-zero energy, single-family model home in Paterson, New Jersey. The structure incorporates three types of insulating foam technologies to reduce energy consumption. Additionally, the building uses ENERGY STAR certified, low-e, glazed windows to block solar heat gain while allowing natural daylight into the home. Air-sealing included weather-stripping around windows and doors.</div>\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_10  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_11  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				<div class=\"et_pb_text_inner\">Baseline Home vs. Model of Energy Efficient New Home in NJ.<br />\nThis study investigated the costs and benefits of different residential energy efficiency scenarios, including advanced framing and upgraded insulation, compared to a baseline, single-family detached home.<br />\nThe basic framing/insulation upgrade used a 2×6 @ 24” on-center advance framing technique. This model upgrade included the following insulation improvements:</p>\n<p>Foundation walls insulated with R-20 rigid extruded polystyrene, closed-cell foam insulation.[7]<br />\nAbove-grade walls insulated with rigid foil-faced isocyanurate, a closed-cell, rigid foam insulation with an R-value of 7 per inch.[8]</p>\n<p>Study results showed that the basic framing and insulation upgrade had a lower initial investment ($19k, or 19%) as compared to the baseline and saved approximately $300, or 9% in annual operating costs.[9]<br />\nThe enhanced framing/insulation upgrade used Insulated Concrete Forms (ICFs) for the foundation walls, Structural Insulated Panels (SIPs) in the above-grade walls, upgraded ceiling insulation of R-70 blown-in cellulose, and fiberglass floor insulation with a higher R-value of 49.[10]<br />\nStudy results showed that the enhanced framing and insulation upgrade cost less in initial investment ($ 1k) as compared to the baseline and saved approximately $500, or 16% in annual operating costs. [11]<br />\nBenefits<br />\nAn important benefit of a properly insulated new home includes lower costs of mechanical systems. An adequately insulated new home allows for the installation of an appropriately sized HVAC system. Older, poorly insulated buildings often require oversized HVAC systems to accommodate for the loss of conditioned air through air leakage. Sealing air leaks and adding insulation can increase occupant thermal comfort and save an average of 10% on annual energy costs.[12] Properly insulated homes maintain comfortable indoor temperature and humidity levels and guard against outside noise, pollen, dust, and insects.[13]<br />\nCosts<br />\nThe cost of implementing a highly insulated building envelope vary depending on the size and orientation of the home, climate, design elements, and the type of insulation and building material. Annual energy savings and incentives offered by the NJ Office of Clean Energy can help offset upfront costs.<br />\nWhile foam insulation products and installation typically have higher first costs compared to traditional batt insulation, foam insulation has lower life-cycle costs due to reduced construction time for installation, and the avoided costs associated with weatherizing a home (i.e., caulking, house wrapping, vapor barriers) because of its high R-value and tight air barrier.[14]<br />\nFor information about costs for various insulation materials see Home Advisor: Insulation Costs: https://www.homeadvisor.com/cost/insulation/#closing-article<br />\nResiliency<br />\nA properly insulated home offers several essential resiliency benefits. In the event of a power outage, well-insulated homes protect against heat loss in the winter and heat gain in the summer, helping to maintain comfortable internal temperatures for building occupants. Wall assembly systems (with insulating properties) such as precast concrete panels, insulated concrete forms (ICFs), and structural insulated panels (SIPs) offer resistance to hazards such as fire, wind, earthquakes, and floods, and improve indoor environmental quality through resistance to mold.[15]<br />\n&nbsp;<br />\n[1] US DOE: Insulation Fact Sheet. 2008. https://web.ornl.gov/sci/buildings/docs/factSheets/Insulation-FactSheet-2008.pdf (accessed May 4, 2018).<br />\n[2] US DOE: Energy Saver. “Insulation” https://www.energy.gov/energysaver/weatherize/insulation (accessed May 29, 2018).<br />\n[3] Rutgers Center for Green Building (RCGB). 2011. “Costs and Benefits of Residential Energy Efficiency Investments.” Prepared for the New Jersey Association of REALTORS® Governmental Research Foundation.

Advances in materials, optics, electronic design, and smart sensors and controls, including lighting technologies paired with networked lighting controls, promise to offer additional performance and efficiency gains and an enhanced occupant experience through daylight harvesting, vacancy sensing, and task tuning. [6] By providing a foundation for future applications of the IoT (Internet of Things), networked lighting controls may also hold the potential to create new benefits and functions beyond supplying basic illumination, such as enhanced security, indoor environmental quality monitoring, and remote maintenance and service (see Smart Sensors and Controls).[7]</p>\n<p>How to Incorporate a High-Efficiency Lighting System and NCLs?<br />\nUpgrading to high-efficiency lighting systems and NCLs in existing buildings involves complex interactions among multiple building systems and disciplines, requiring an integrated design process (see Integrated Design Process). For example, window glazing influences interior electrical lighting design, sizing of mechanical systems, and interior design layouts (see Windows and Skylights, Glare and Heat Gain Reduction, and Properly-Sized, High-Performance HVAC Equipment and Controls). Renovations also provide an opportunity to assess current natural light and electrical lighting levels and identify opportunities for improvement.<br />\nThe first step to a high-efficiency lighting upgrade is to conduct a lighting audit or survey that establishes information about all the lighting technologies and consumption patterns in a building. Hire a lighting specialist and/or use Energy Star Portfolio Manager to benchmark energy usage and identify lighting upgrade opportunities. Based on the study, identify suitable replacement solutions including lamps, luminaires, and controls, and devise an implementation program.<br />\nLighting upgrade guidelines, such as the EnergyStar Building Upgrade Manual Chapter 6: Lighting, provide general principles and examples, but project specific solutions often require hiring a daylighting and lighting expert familiar with advanced computer simulation software and tools that can effectively simulate a range of scenarios and outcomes.[8]<br />\nThe following provides general best practice guidance on how to optimize daylighting and electrical lighting in existing commercial buildings.[9]</p>\n<p>Set a Maximum Lighting Power Density (LPD) goal to avoid overlit spaces and to achieve an appropriate level of lighting per area lit or watts per square foot.<br />\nSet a Daylight Sufficiency Goal that establishes the amount of daylighting, measured in lumens or foot-candles, required to perform a typical task in each space without electrical lighting.<br />\nDevelop a layered lighting strategy that first utilizes daylight to provide primary or ambient lighting levels, and then adds electrical lighting options and controls to vary lighting levels for a variety of tasks and occupant preferences.<br />\nSpecify lighting products from the DesignLights Consortium or ENERGY STAR qualified product lists.<br />\nUse vacancy sensors (manual on, automatic off) as opposed to occupancy sensors (automatic on, automatic off) to save energy by requiring occupants to flip a switch if they require additional light.<br />\nProvide adjustable task lighting at individual workspaces to save energy by directing appropriate lighting to specific tasks.<br />\nIncorporate exterior motion sensors to save energy and enhance security and safety.<br />\nConsider photo-luminescent egress signage subject to local fire code.<br />\nPlan for backup power for critical lighting needs during a power outage, such as emergency and night-time lighting (see Energy Storage and Backup Power Generation).<br />\nCommission and regularly re-commission all lighting systems and controls to optimize performance and energy savings.</p>\n<p>Examples<br />\nGSA Proving Ground – TLED Lighting Retrofits with Dedicated Drives<br />\nThis case study conducted by the Pacific Northwest National Laboratory (PNNL) looked at the energy saving benefits of replacing Linear Fluorescent Lamps (LFLs) with Light-Emitting Diode (LED) lamps and with Advanced Lighting Controls (ALCs), such as dimming and occupancy sensing that do not require modifications to the existing ceiling for installation. The study found LED energy savings ranging from 27%-29% when LEDs replaced T8 LFLs with electronic ballasts.<br />\nBenefits<br />\nSupplementing natural daylight with high-efficiency lighting systems and NLCs provides multiple benefits:</p>\n<p>Reduced operating costs through energy efficiency gains and reduced maintenance and replacement costs through longer-lasting bulbs and fixtures.[10]<br />\nReduced cooling loads and downsized HVAC systems through less heat gain from electrical lighting (see Properly-Sized, High-Performance HVAC Equipment and Controls).[11]<br />\nReduced number of toxic chemicals released into the waste stream and reduced light pollution.<br />\nImproved employee productivity and satisfaction based on a shared preference for naturally daylit spaces, reinforcement of circadian rhythms, and connection to nature.[12]<br />\nAbove average lease rates and lower tenant turnover.[13]</p>\n<p>Costs<br />\nHigh-efficiency lighting design and NLCs should not impose a significant impact to project costs if considered early in the design phase and integrated throughout the design process. The costs of hiring an expert daylighting consultant and electrical lighting designer often pay for themselves through electrical lighting reductions and associated energy cost savings.<br />\nThe table below shows costs for Commercial and Industrial LED Luminaries[14]<br />\nCheck the New Jersey Office of Clean Energy for available incentives. At the time of this writing, incentives for lighting controls range from $20-$45 per fixture. The incentives for performance lighting are $1.00 per watt below the allowable wattage as determined by ASHRAE 90.1-2013 baseline and $30 per eligible fixture. Prescriptive lighting incentives range from $5 to $150 per fixture.<br />\nResiliency<br />\nImplementing high-efficiency lighting and NCLs provides energy savings and reduces reliance and stress on the electricity grid. Daylit-optimized buildings paired with high-efficiency lighting systems and built-in backup power for critical lighting needs further reduce stress on the grid, especially in the event of a power outage.<br />\n[1] Whole Building Design Guide.

class=\"et_pb_text_inner\">What is Light Pollution?<br />\nLight pollution refers to noticeable artificial light at night (ALAN), an unwelcome by-product of excessive outdoor lighting, especially vertical illuminance that includes such effects as skyglow, the brightening of the night sky, light trespass, the spilling of light beyond a property or intended lighting boundary, and glare, the obtrusive brightness of light viewed against an unlit background.[1] The commercial building sector contributes to light pollution through a variety of sources, including advertising lighting, architectural and landscape lighting, interior nighttime lighting, and security lighting.<br />\nThe following includes a list of several negative impacts of light pollution.</p>\n<p>Interferes with wildlife migratory and breeding patterns, impacting nighttime ecosystems and biodiversity.[2]<br />\nWastes energy and contributes to greenhouse gas emissions.<br />\nLeads to glare issues and unsafe driving conditions, particularly for older motorists.<br />\nImpacts human metabolism and disrupts sleep through constant exposure to artificial light, particularly light from the blue end of the spectrum.[3]<br />\nReduces ability to view stars and interferes with astronomical observatories. [4]<br />\nCauses a nuisance to neighboring properties by casting unwanted nighttime glare into windows.</p>\n<p>How to reduce light pollution?<br />\nThe first steps to reducing light pollution are to evaluate the outdoor lighting requirements of a particular location (i.e., aesthetics, security, or utility), to eliminate unnecessary lighting, and to strategically place energy-efficient lighting and controls to meet the remaining lighting requirements (see High-Efficiency Lighting and Networked Lighting Controls).<br />\nDownlighting refers to a lighting strategy that directs light down and only lights the predetermined area; therefore reducing light pollution. Technologies to reduce light pollution also include full cutoff luminaires, low-reflectance surfaces, and low-angle spotlights. Cutoff luminaires have no direct uplight, help eliminate glare, and efficiently direct lighting down to the predetermined area.<br />\nGeneral guidelines for efficient outdoor lighting include:</p>\n<p>Consider location and surrounding areas during the lighting design, and select luminaires, locations, and orientations that minimize light trespass onto adjacent properties.<br />\nReplace traditional HIDs (high-intensity discharge) luminaires and lamps, including high-pressure sodium and metal halide lamps, with EnergyStar certified outdoor LEDs.<br />\nConsider installing solar powered outdoor LED lights for outdoor pathways.<br />\nAim floodlight angles low so that the entire beam falls within the intended lighted area and direct light downward whenever possible.<br />\nUse well-shielded luminaires and lamps, and other control devices when up-lighting is required to maximize the efficiency of the light source (e.g., reflectors, deflectors, and covers).<br />\nCouple outdoor lightings systems, with lighting controls such as motion detectors, photosensors, and schedule controls, to enhance an energy efficiency and security.<br />\nAdjust timers to the minimum period necessary and dim or switch lights off when not needed to save energy and cut electric bills.<br />\nPlan for backup power for critical lighting needs during a power outage, such as emergency and night-time lighting (see Energy Storage and Backup Power Generation).<br />\nCommission and regularly re-commission all lighting systems and controls to optimize performance and energy savings.</p>\n<p>For project specific advice, consult the Illuminating Engineering Society’s lighting design guides, which provide lighting professionals with standards and recommended best practices for a variety of lighting applications.<br />\nBenefits<br />\nEfficient outdoor lighting design helps to reduce light pollution, and its associated adverse effects including wasted energy reduced nighttime visibility for astronomers and scientists, disruption of nocturnal wildlife and ecology, and impacts on human health and well-being.[5]<br />\nCosts<br />\nThe costs of implementing lighting designs and technologies that reduce light pollution vary depending on the selection of lighting sources, fixtures, and controls. Effective and efficient outdoor lighting solutions are not always the least expensive option, but as with any comprehensive cost evaluation, operating costs, including energy savings, lifetime performance, and maintenance, are essential factors to consider.[6]<br />\nCheck the New Jersey Office of Clean Energy for available incentives.<br />\nResiliency<br />\nReducing light pollution provides energy savings and reduces reliance and stress on the electricity grid. Outdoor lighting designs that supplement solar-powered LED lighting technologies for a portion of regular lighting requirements (e.g., pedestrian pathways) and plan for backup power for critical lighting needs further reduce stress on the grid, especially in the event of a power outage.<br />\n&nbsp;<br />\n[1] The Lighting Research Center, Rensselaer Polytechnic Institute. http://www.lrc.rpi.edu/programs/transportation/pdf/lightPollution/Seminarpresentation.pdf (accessed October 22, 2018).<br />\n[2] Gaston KJ, Visser ME, Ho ̈lker F. 2015 The biological impacts of artificial light at night: the research challenge.

Passive chilled beams rely on the natural buoyancy of air to circulate through the heat exchanger, usually coils, to cool the air. In a passive system (most often used for cooling), hot air rises and becomes trapped in a space located above the chilled beams. Once the hot air interacts with the lower temperature beams, it naturally falls back into the room. Unlike active beams, passive beams are not directly connected to the ducted air supply and require a parallel ventilation system to handle dehumidification and latent loads and provide the primary air to drive the passive beam system.[3] Active systems direct air through the use of nozzles to the cooling or heating coils and allow for humidity control. Multi-purpose chilled beams can be used to supply other buildings services, such as lighting, speaker systems, IT systems, fire protection (sprinklers and detectors), acoustic insulation, Building Automation System sensors, and photocells.</p>\n<p>How to Incorporate Chilled Beams<br />\nChilled beams require specific applications but are often good candidates for retrofit projects and upgrades to HVAC systems in existing buildings due to their limited space requirements and ease of installation. However, chilled beams require specific applications and each chilled beam system design is unique, requiring project engineers to work closely with the manufacturer’s engineers in the design and selection of the chilled beam.[4]<br />\nAccording to best practice guidance from ASHRAE and REVHA chilled beams work best in applications with low air-side load fractions (or the percentage of the total air supply required by code for a zone) and in applications with high sensible heat ratios (or the percentage of the cooling load that is sensible compared to latent). For example, chilled beam systems can offer benefits over conventional systems if the sensible cooling load is substantially higher than the capacity of the air supplied to satisfy the latent loads.[5]<br />\nFor comprehensive tools and guidance on designing, commissioning, and operating active and passive beam systems refer to the joint publication by ASHRAE and REVHA, “Active and Passive Beam Application Design Guide.” Available for purchase at https://www.ashrae.org<br />\nANSI/ASHRAE Standard 200-2018, Methods of Testing Chilled Beams, establishes testing methods and procedures for determining the performance of chilled beams. Certification programs (Eurovent, AHRI) guarantee the accuracy of manufacturers’ technical data.<br />\nExample<br />\nNew Jersey Institute for Food, Nutrition, and Health, Rutgers University, New Brunswick, NJ.<br />\nThe IFNH building at Rutgers University, designed by Ballinger Architects finished in 2015 and built to LEED Gold standards is the first Rutgers University building to incorporate chilled beams as part of the building’s open laboratory design.</p>\n<p>Benefits<br />\nChilled beams have the potential to save significant amounts of energy and operating costs compared to completely air-based systems because they move heat more efficiently by using water instead of air as the heat transfer fluid, reducing the reheat and fan energy required to operate the system.[6] Chilled beams also increase the usable floor space and ceiling height in a building by eliminating additional ductwork and equipment space requirements and allowing for modular configurations and flexible installations. Other advantages include enhanced thermal comfort (e.g., uniform air distribution), acoustic control (e.g., quiet operation) and indoor air quality (e.g., utilize 100% outside air and limit room to room air recirculation).[7] Finally, chilled beams offer lower maintenance and repair costs due to fewer mechanical components than conventional HVAC systems.<br />\nCost<br />\nThe cost of chilled beams varies depending on the design and application. Chilled beams often have higher materials costs than conventional VAV systems but lower installation, maintenance, and energy costs. For example, by requiring fewer air exchanges, chilled beams can result in the downsizing of ductwork, air-handling units, exhaust fans, chillers, and boilers, reducing first costa and helping to offset the cost of chilled beam infrastructure.[8] The growing number of certified manufacturers and installers and available incentives are also helping to make chilled beams more cost competitive with conventional technologies.<br />\nSee the NJ Clean Energy Program for current incentives and programs http://www.njcleanenergy.com<br />\nResiliency<br />\nChilled beams contribute to resiliency by decreasing energy consumption, including peak loads, which decreases reliance and stress on the electricity grid.<br />\n&nbsp;<br />\n[1] ASHRAE and REHVA. 2015. “Active and Passive Beam Application Design Guide.”<br />\n[2] ASHRAE and REHVA. 2015. “Active and Passive Beam Application Design Guide.”<br />\n[3] Energy Design Resources. 2010.

Ventilation systems typically provide a constant flow of fresh air to occupants based on maximum building occupancy or full ventilation rates in contrast to a minimum or area ventilation rate based on reduced occupancy levels. Demand control ventilation (DCV) modulates between full and area ventilation rates based on actual or estimated occupancy levels, saving energy and improving indoor air quality. DCV systems can measure occupancy levels and adjust ventilation using one or more of the following methods:[1]</p>\n<p>Carbon dioxide (CO2) sensors that adjust airflow based on CO2 levels or the number of occupants in a space.<br />\nOccupant counting which counts actual or estimated occupants in a space using ticket sales, security swipes or video monitoring.<br />\nOccupancy sensors that detect occupancy and switch between full or area ventilation rates.<br />\nScheduled ventilation based on estimated and scheduled occupancy.<br />\nSet supply air CO2 concentrations based on design occupancy conditions in designated zones.</p>\n<p>Figure 1 compares the different DCV methods and corresponding ventilation rates in response to changing occupancy levels.</p>\n<p>How to Implement Demand Control Ventilation<br />\nProper ventilation and good indoor air quality start with eliminating or reducing familiar sources of indoor air pollution such as off-gassing from building materials and furnishings.<br />\nWhen incorporating a DCV system into an existing ventilation system, best practices include using zone occupancy sensors for small and less densely occupied zones, and CO2 sensors in large or densely occupied spaces, both with setpoints that follow the specific guidelines in Appendix A of the ASHRAE Standard 62.1 User’s Manual.[2] Well-designed and executed DCV systems take into account user requirements, operator training, and coordination among different building systems, such as occupancy sensors used for lighting and air flow. Commissioning and recommissioning provides an opportunity to check DCV set-points and offer potential energy and cost savings.<br />\nExamples<br />\nEnergy Savings from Implementing and Commissioning Demand Control Ventilation (DCV), Case Study, Minnesota.<br />\nInformation on a subset of six building systems collected from 32 buildings was taken across all seasons using building automation system data and instrumentation to document energy savings and indoor air quality before and after recommissioning of Demand Control Ventilation (DCV) systems. Building occupants also completed a comfort survey. System designers and operators provided lessons learned. Results showed that DCV implemented in large VAV systems can provide significant energy and cost savings in cold climates and recommissioning either provides additional energy savings or increased indoor air quality.[3]<br />\nOradell Public School, Oradell, NJ<br />\nThe Oradell Public School conducted an energy audit as part of the New Jersey Board of Public Utilities’ Local Government Energy Audit Program. The report recommended Demand Control Ventilation (DCV) as an Energy Conservation Measure (ECM) to reduce energy and utility costs and to improve indoor air quality. The following summarizes the estimated implementation costs and savings for Demand Control Ventilation (DCV):</p>\n<p>Electricity Savings: 18,400<br />\nNatural Gas Savings: 2,700<br />\nEstimated Savings: $5,200<br />\nEstimated Installed Cost: $10,000<br />\nPayback Period: 1.9</p>\n<p>Benefits<br />\nVentilation requires energy to heat or cool outside air. Demand control ventilation (DCV) saves energy by reducing ventilation rates during times of vacancy and reduced peak occupancy. DCV improves indoor air quality, contributing to occupant health and productivity, by closely monitoring CO2 concentrations and occupancy levels that impact indoor air pollution and air quality.<br />\nCosts<br />\nCompared to conventional ventilation systems, demand control ventilation adds up-front costs depending on the complexity and size of the system and number of sensors installed, ranging between $1 – $3 per cfm of outside air.[4]<br />\nResiliency<br />\nDemand control ventilation (DCV) offers an indirect resiliency benefit to buildings by reducing heating and cooling loads, thereby reducing stress on the grid, and the likelihood of brownouts.<br />\n&nbsp;<br />\n[1] U.S. DOE. “Demand-Controlled Ventilation.” https://www.energycodes.gov/sites/default/files/documents/cn_demand_control_ventilation.pdf  (accessed May 31, 2018).<br />\n[2] SeventhWave. 2015.

In addition, as HVAC systems age and parts of the system experience decline in performance or failure due to wear and tear, the system becomes less efficient. Also, design engineers often oversize HVAC systems to comply with code or to meet the most extreme loads such as the coldest and hottest days of the year, and design systems with a built-in capacity for overloads which occur only 1% to 2.5% of the time.[2] Oversized equipment can result in higher installation and capital costs, reduced operating efficiency, and potential negative impacts on comfort. For example, short-cycling or excessive cycling of air conditioning equipment can lead to poor humidity control and moisture or mold issues and contributes to the wear and tear and longevity of equipment. Oversized systems use more fan power for blowers and can increase peak demand during the cooling season, leading to higher energy costs.[3] Oversizing can occur for a variety of reasons. Contractors may use standard rules of thumb based on experience rather than industry accepted practices and customers often request oversized units without understanding the calculations that go into sizing equipment or to accommodate planned expansions.[4]<br />\nFurthermore, many existing buildings are never commissioned to ensure that HVAC systems and HVAC controls, which regulate HVAC systems to maintain occupant comfort and save energy, are working correctly (see Re-Commissioning). Controls give operations and maintenance personnel the ability to monitor and adjust the HVAC system based upon real-time changes in the outdoor environment and indoor occupancy levels (see Smart Sensors and Controls). Controls include but are not limited to programmable thermostats to reduce heating and cooling loads (temperature), variable frequency drives (ventilation), occupancy sensors (lighting), and system integrated windows, all of which can have a significant impact upon the indoor environmental quality of a given space. Ongoing training for building operators and commissioning can ensure that HVAC systems and controls work effectively.<br />\nProperly-sized, high-performance HVAC equipment, and controls consider the interaction among building systems, and the potential synergies and contradictions among these systems, taking into account the energy savings achieved through building envelope strategies, smart controls, and occupant behaviors when selecting equipment and designing air distribution systems (see Integrated Design Process, Roof Replacement and Upgrades, Windows and Skylights, and Exterior Wall System Upgrades).</p>\n<p>How to Implement Properly-Sized, High-Performance HVAC Equipment<br />\nFirst, commission the HVAC system or conduct commissioning on the whole building that includes a comprehensive energy audit to determine the costs and benefits of energy efficiency improvements, operation and maintenance changes, and HVAC equipment upgrades. The evaluation process should include an examination of all the components of the HVAC systems for wear and tear, from the most expensive components to the piping and insulation.[5] Use the results of the energy audit and final commissioning report to incorporate energy-efficient strategies that reduce heating and cooling loads. Select appropriately sized, high-performance HVAC equipment and controls that reflect the impact of different energy-efficient design measures and building operations on peak heating and cooling loads and overall system loads as well as how often the system runs on part load (see Chilled Beams, Demand Control Ventilation, Natural Ventilation, Thermal Energy Storage, and Variable Frequency Drives). Consider part-load performance when selecting equipment as most heating, and cooling equipment fails to operate at peak efficiency unless fully loaded (see Part-Load Efficiency).[6] One approach to downsizing HVAC equipment uses a small, efficient system to manage normal loads, and designates a backup system or relies on energy storage for extreme conditions that demand additional load capacity and occur less frequently (see Energy Storage and Back-up Power Generation, Thermal Energy Storage).[7] In general, properly sizing HVAC equipment avoids providing excess capacity and allocates extra physical space for additional equipment and designs modular distribution systems that can accept additional equipment for future expansion.[8]<br />\nThe Air Conditioning Contractors of America (ACCA), Manual N, “Commercial Load Calculation,” and provides industry-accepted standards for properly sizing HVAC systems, and the ACCA Manual Q, “Commercial Duct Design,” provides guidance and performance criteria for duct system design.</p>\n<p>Example<br />\nGSA’s Emerging Building Technologies – HVAC Published Findings<br />\nThe General Service Administration’s Emerging Building Technologies program publishes case study findings, such as innovative and cost-effective HVAC technologies to inform decision making on federal buildings.<br />\nBenefits<br />\nProperly-sized, high-performance HVAC equipment and controls reduce energy consumption, water use and emissions, provide cost savings, manage occupant comfort and maintain indoor air quality.<br />\nCosts<br />\nIncorporating a whole-building energy-saving approach including envelope strategies, high-performance lighting, and energy-efficient windows can reduce peak heating and cooling loads and result in smaller HVAC systems that cost less upfront than larger capacity models and save 30% on average on annual utility costs  (see High-Efficiency Lighting and Networked Lighting Controls, and Windows and Skylights).[9] Additional upfront costs for commissioning and energy audits often pay for themselves through realized energy and cost savings.<br />\nFor information on available HVAC equipment incentives, visit The New Jersey Clean Energy’s Smart Start Building Program. State incentives tend to be in the form of low-interest loans, grants, and tax incentives for the greening of buildings.[10]<br />\nResiliency<br />\nProperly-sized, high-performance HVAC equipment and controls increase resiliency by decreasing energy and water consumption and peak loads which decreases reliance and stress on the electricity grid natural gas, water, and wastewater infrastructure.<br />\n&nbsp;<br />\n[1] Whole Building Design Guide. 2016.

drive, adjustable-speed drive or inverter refers to a device that controls the voltage and frequency supplied to a motor, varying the speed of a motor or the flow in distribution systems.[1] Flow can refer to various systems such as water, air or energy. Many applications and existing commercial HVAC systems use fixed or single speed motors and regulate flow and pressure with dampers and valves, which can throttle and reduce efficiency.[2]<br />\nVFDs on fans (e.g., supply and return fans, exhaust fans, boiler fans, or condenser fans) save energy by allowing the volume of air moved to match the system demand. VFDs can control the speed of electric motors by applying a low frequency and a low voltage during motor startup, then ramping up to accelerate the load while limiting current. During a shutdown, VFDs can also allow motors to ramp down at a controlled rate. [3] When applied to a HVAC system, more specifically the air handling units (AHU), VFDs can vary motor speed to precisely match the load, a critical energy-saving measure for frequently oversized HVAC systems that work inefficiently at part-load (see Part-Load Efficiency and Properly-Sized HVAC Equipment).[4]</p>\n<p>How to Incorporate Variable Frequency Drives<br />\nCoordinate work between the mechanical engineer and contractor to determine opportunities to install VFDs and to size VFDs to match load requirements accurately. In general, existing systems with constant speed motors that already modulate flow with mechanical devices provide a better match for VFD retrofits than existing systems that require constant flow.[5]<br />\nExample<br />\nRutgers University Campuses, New Brunswick, Newark and Camden, NJ.<br />\nUniversity engineers at Rutgers conducted a comprehensive energy audit and identified the opportunity to save energy and costs by installing premium efficiency motors and variable frequency drives at multiple campus buildings spanning several university locations. The project expects to have a three-year payback and save an average of 2.8 million kilowatt hours of electricity and prevent the release of 1,500 tons of CO2 on an annual basis.[6] VFDs can also contribute to demand reduction under the right operational scenario.<br />\nBenefits</p>\n<p>Minimizes mechanical and electrical stress on the motor system, lowering maintenance and repair costs and extending motor life.[7]<br />\nReduces the horsepower (HP) required to run a system by the cube of its motor speed, providing significant energy, demand and costs savings when motor speeds can vary to match a load.[8]<br />\nEnhances overall system performance by matching system capacity to the actual load.<br />\nAllows for improvements in thermal comfort which can impact occupant satisfaction and productivity.</p>\n<p>Costs<br />\nThe cost of incorporating VFDs into an existing HVAC system depends on the characteristics of the existing system and on the manufacturer and supplier. Equipment costs also vary depending on the horsepower (HP) rating, ranging from $1,000 for 5 HP VFD models to $15,000 for 200 HP VFD models.[9] Energy savings from reduced maintenance and longer equipment life and available incentives can reduce payback periods and increase long-term savings.<br />\nCheck the New Jersey Office of Clean Energy for available incentives.<br />\nResiliency<br />\nVFDs increase resiliency by decreasing energy and water consumption, and peak loads which decreases reliance and stress on the electricity grid and natural gas and water and wastewater infrastructure.<br />\n&nbsp;<br />\n[1] Bernier, Michael A, and Bernard Bourret. 1999.

Figure 1 shows several different types of water heaters, including storage, tankless, heat pump, solar, and tankless coil, and indirect water heaters.<br />\nConventional, storage water heaters hold hot water in a tank, while tankless water heaters only heat the water upon demand. Heat pump water heaters use electricity to transport heat from one source to another (e.g., air-source heat pumps, geothermal heat pumps) instead of providing heat for hot water directly (see Geothermal Heat Pumps).[1] Solar water heaters utilize the sun’s heat and tankless coil, and indirect water heaters use a building’s heating system to provide domestic hot water (see Solar Thermal Systems).<br />\nTypical energy sources for high-efficiency water heaters include natural gas, propane, electricity, and solar. The availability and cost of any of these sources or combinations of these sources can dictate equipment and system selection along with other selection criteria including the home’s hot water requirements such as usage times, amount of water use, temperature range, and flow rates.</p></div>\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_1  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_2  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				<div class=\"et_pb_text_inner\">How to Incorporate a High-Efficiency Water Heater<br />\nSelecting a high-efficiency water heater is part of a whole home water conservation strategy to reduce indoor water consumption by specifying water-efficient fixtures, equipment, and systems (see Indoor Water Conservation).

Use rainwater collected in barrels from catchment areas such as rooftops for irrigation, flushing toilets and other non-potable uses (see On-site Alternative Water Reuse). Treat or filter the water depending on the intended use.<br />\nStandard components of a rain harvesting system include[1]</p>\n<p>Catchment area such as a roof<br />\nGutters and downspouts<br />\nLeaf screens<br />\nRain barrel for storage<br />\nConveyance system to deliver stored water via gravity or pump<br />\nWater treatment or filter system</p></div>\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_6  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_7  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				<div class=\"et_pb_text_inner\">How to Incorporate Rain Barrels<br />\nSet aside sufficient space, either interior, above ground or underground, for the appropriately sized barrel. Residential rain barrels can range in size but typically hold 55-gallons. To calculate the volume of water available for capture, assume that every 1,000 square feet of catchment area generates 600 gallons of runoff during a one-inch rainfall event.[2]</div>\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_8  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_9  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				<div class=\"et_pb_text_inner\">Consider combining rain barrels with a drip irrigation system to direct overflow to a dry well, rain garden or bio-retention area.<br />\nRain barrels require maintenance. Use water within two weeks to prevent algae growth and clean barrels every few months. A screen with a cover prevents algae growth and mosquito breeding. Drain, disconnect and store rain barrels during the winter months.<br />\nFor more detailed information about the design and construction of rain barrels see the Rutgers Water Resources Program’s – Green Infrastructure Manual for New Jersey.<br />\nExample<br />\nResidential Rain Barrel, Lakehurst, NJ<br />\nPart of the Rutgers Sustainable Landscape Demonstration Site Program, the Lakehurst residential renovation project included a 35-gallon rain-barrel or repurposed trash can to collect and redirect water to an adjacent ornamental flower bed, eliminating the need for on-site irrigation and municipal water use.<br />\nBenefits</p>\n<p>Reduces demand for potable water for irrigation and other non-potable uses (see Water-Efficient Landscape Design).<br />\nLowers peak demand and peak discharge rate on public water systems.<br />\nReduces overall potable water use and saves money on water bills.<br />\nReduces stormwater runoff via storage (see Emergency Water Supply and Storage).<br />\nReduces runoff of contaminants into soils and waterways.</p>\n<p>Costs<br />\nCosts vary depending on the size and type of rain barrel selected. Small-scale systems cost around $60 for a 55-gallon barrel.[3] Some watershed associations or municipalities offer rain barrels at a discount or provide rebates.<br />\nResiliency<br />\nWater stored in rain barrel can provide an alternative water source for non-potable uses during storms, hurricanes and droughts or when municipal water sources are shut down or become polluted. Filter and purify before using the water to irrigate edible gardens, wash dishes, or provide water for drinking and showering. Rain barrels also help mitigate flooding by capturing water that would end up in the municipal water system.<br />\n&nbsp;<br />\n[1] US DOE | EERE. “Best Management Practices:  Alternate Water Sources.”  https://www.energy.gov/eere/femp/best-management-practice-14-alternative-water-sources (accessed April 2, 2018).<br />\n[2] Rutgers Water Resources Program.

of distributed energy resource that produces both electricity and thermal energy onsite, using one primary fuel.[1] CHP recovers heat usually wasted in conventional power generation as thermal energy for a building’s space heating and cooling, process heating and cooling, dehumidification, or the production of more electricity generation.[2] CHP system can use fossil or renewable fuels and typically utilize the following prime mover technologies to combust the fuel including reciprocating engines, gas turbines, microturbines, fuel cells, and boiler or steam turbines.<br />\nFor example, (see Figure 1) a prime mover, such as a reciprocating engine or gas turbine uses a fuel such as natural gas to power a generator that creates electricity and emits heat. Generated electricity supplies electrical loads in the building, feeds back to the grid, or utilizes energy storage for later use (see Energy Storage and Backup Power Generation). A heat recovery unit captures the heat and processes it for use onsite, typically for building heating applications but also for absorption cooling, an application that utilizes heat energy to cool buildings.[3] CHP systems can utilize thermal energy storage to save excess heat energy for later use when it is needed, such as during a power outage, to increase energy efficiency, and to store low priced energy and use that energy during peak demand when prices climb (see Thermal Energy Storage).[4]<br />\nMicroturbines use gaseous or liquid fuels, most commonly natural gas, to produce electricity and recover exhaust heat for direct use or use in a heat recovery boiler.[5] Steam turbines do not consume fuel directly but use steam generated by natural gas, oil, coal or biomass driven boilers or heat recovery steam generators, to produce power and thermal energy (see On-Site Renewable Energy Systems).[6]<br />\nFuel cells used for CHP applications utilize an electrochemical process to reform natural gas or biogas into hydrogen and then react hydrogen to generate electricity.[7]<br />\nHow to Integrate CHP<br />\nThe practicality of integrating CHP into a project increases when considered early in the planning stages, including early engagement with the local utility to identify permitting issues and available incentives.<br />\nContact the NJ Office of Clean Energy to learn about current CHP programs, tools, and available funding. For example, the NJ Office of Clean Energy Combined Heat and Power (CHP) Program currently offers incentives for the following CHP technologies:[8]</p>\n<p>Powered by non-renewable (i.e., natural gas) or renewable fuel source (i.e., biomass).<br />\nGas internal combustion engine.<br />\nGas combustion turbine.<br />\nMicroturbine<br />\nFuel cells with heat recovery.<br />\nWaste heat to power.</p>\n<p>The use of Class 1 renewable fuel sources and installation of CHP with black-start and islanding capabilities at designated critical facilities may qualify projects for additional incentives.<br />\nExample<br />\nWestin – Starwood Hotel, Jersey City, NJ<br />\nThe Westin Jersey City Newport qualified for the NJ Clean Energy Combined Heat &amp; Power Program by installing three Tecogen® Inc. 100-kW natural gas engine CHP units. The co-generation units are expected to produce 1,985 MWh of electricity and 132,962 therms of energy per year. The Westin Jersey City Newport qualified for $600,000 in NJCEP incentives, covering more than 27 percent of the $2,158,229 project cost, which includes ten years of maintenance service by the manufacturer. The co-generation units could potentially save the hotel, on average, 367,209 kWh of electricity and 91,198 therms of natural gas per year, resulting in annual savings ranging from $123,007 to $212,000. With the NJCEP incentives, the project expects to pay for itself within a decade when factoring in federal tax credits.<br />\nBenefits<br />\nInherently inefficient, conventional electricity generation converts only about a third of a fuel’s potential energy into usable energy.[9] It is reasonable to expect CHP applications to operate at 65-75% efficiency, a large improvement over the national average of ~50% for these services when separately provided.[10] Since overgeneration of heat and electricity occurs frequently, CHP systems that utilize both thermal and electrical storage further increase energy efficiency by capturing wasted energy.[11] The significant increase in energy efficiency with CHP means lower fuel consumption and reduced greenhouse gas emissions for the same level of output when compared to the separate generation of heat and power. Biomass powered CHP systems have the added benefit of generating both low-carbon electricity and low-carbon heat, further increasing energy efficiency and reducing carbon emissions by utilizing waste heat and using fuel more efficiently (see On-Site Renewable Energy Systems).[12] Other benefits include CHP’s proven track record and the versatility of CHP to work with existing and planned technologies for various industrial and commercial applications. CHP also localizes energy generation, avoiding congestion issues and improving grid transmission and distribution losses associated with centralized power stations, reducing the risk of electrical grid disruptions and enhancing energy reliability. As a distributed energy generator, CHP provides a reliable and independent source of electric power during power emergencies and grid outages and can help to manage peak demand and lower utility costs throughout the year via demand response programs (see Demand Response and Peak Load Management).<br />\nCosts<br />\nCHP makes the most economic sense when electricity prices are high, and natural gas prices are low. While the initial cost of CHP systems often exceed that of conventional heating or cooling systems, reduced energy and operating costs associated with cogeneration can often justify the investment.<br />\nResiliency<br />\nCHP can improve the resiliency of critical infrastructure, by acting as a self-sufficient microgrid keeping essential facilities and systems running without any interruption in electric or thermal service in the absence of utility sourced power due to storms or other events.[13]<br />\nFor example, South Oaks Hospital in Amityville, New York remained open and operational during Superstorm Sandy while over 8.5 million Long Island Power Authority (LIPA) customers had no power for a week.[14] South Oaks Hospital had five 250 kW units, which kept lights on and refrigeration units operational for 15 days, even allowing the hospital to admit new patients.<br />\nA form of distributed energy generation, CHP systems support the development and integration of microgrids with the broader smart grid by providing a consistent and reliable source of backup power that helps to balance the supply and demand of electricity from other distributed energy generators, including variable renewables such as wind and solar.[15] Combined with energy storage capabilities, CHP systems hold the potential to help diversify and strengthen the electric grid through better energy management and the integration of distributed energy resources and energy storage (see Thermal Energy Storage, Energy Storage and Backup Power Generation).<br />\n&nbsp;<br />\n[1] US EPA and US DOE.

Electricity generated from coal, nuclear, oil, natural gas, wind, and solar all goes to the same grid (see Figure 2). Renewable Energy Credits (RECs) represent 1 MWh of renewable electricity generation and provide proof of the electricity generated by green power.<br />\nEnergy-efficient commercial buildings that are not ideally suited for on-site renewable energy generation can choose to switch to green energy or purchase RECs to help offset their environmental and carbon footprints on a voluntary basis or to meet corporate sustainability goals or other mandates.</p>\n<p>How to Purchase Green Energy<br />\nIn New Jersey, the Electric Discount and Energy Competition Act (EDECA) of 1999 (N.J.S.A. 48:3-49) separated the supply portion of the electric rate from the delivery portion, providing the consumer the opportunity to select among third-party electricity suppliers licensed by the New Jersey Board of Public Utilities (NJBPU). Consumers can make decisions on a variety of factors including cost or energy efficiency and sources of electricity generation (e.g., nuclear, natural gas, oil, solar).[2]<br />\nThrough the purchase of green power, a building does not necessarily receive renewable energy directly, but instead, the purchase of renewable energy increases the percentage that renewable sources (e.g., solar and wind) that contribute to power production within the region. Table 1 lists various ways to purchase green energy.<br />\n&nbsp;<br />\nCommercial electricity consumers may choose to purchase RECs, contract with a green energy supplier or participate in a utility-sponsored green energy program. Green power products and programs often require customers to pay a premium over the standard electric price in return for green power (i.e., electricity bundled with RECs) but the utility continues to provide the electric transmission and distribution in the same way as a regular electric customer.<br />\nNote that green power supply options depend on available renewable energy resources and projects, and state and utility policies and programs. Check with your utility provider for available programs and current incentives. Other options include Power Purchase Agreements (PPAs) that directly support specific renewable energy projects.<br />\nThe decision to purchase green power involves identifying and comparing green power options among verified, third-party certified green power providers that meet nationally-accepted standards for product quality. At this time, the Center for Resource Solutions’- Green e-Certified Program is the only organization that certifies and independently verifies green power products in the United States.<br />\nBenefits<br />\nConventional electricity relies on fossil fuels and produces significant air pollution and greenhouse gas emissions. Green power provides the following environmental and sustainable marketing benefits:[3]</p>\n<p>Supports renewable energy resource and technology development either directly through PPAs and bundled green power products or indirectly through RECs.<br />\nReduces a business’s carbon footprint associated with electricity consumption.<br />\nServes as a marketing tool to demonstrate a business’s commitment to sustainability goals.</p>\n<p>Example<br />\nJacobstown Solar Farm, Burlington County, NJ.<br />\nThe Jacobstown Solar project, by Community Energy, Inc., provides green power to the Jersey Central Power &amp; Light (JCP&amp;L) regional electric grid and helps farmland preservation in the area by providing a source of local revenue. Landscaping on the site matches the rural surroundings and plantings of low mow turf grass reduce stormwater runoff and improve soil conditions for future agricultural uses. When NJ businesses choose to purchase green power, they support solar companies like Community Energy, Inc. and projects like the Jacobstown Solar Farm, that provide local sources of renewable energy.<br />\nCosts<br />\nWhile a switch to green power does not require any upfront capital costs, currently there exists a cost premium for green power of about 2 to 4 cents per kWh.[4] Prices for green power vary also depending on a variety of factors, including:</p>\n<p>Supply and demand variability<br />\nProduct type (e.g., RECs, PPAs, utility or competitive green power products)<br />\nPurchase volume (e.g., total kilowatt-hours)<br />\nContract length (e.g., short- or long-term)<br />\nResource and technology type (e.g., solar, wind)<br />\nGeography (e.g., local versus national)<br />\nCertification and verification status</p>\n<p>Resiliency<br />\nA switch to green power provides resiliency benefits by helping to diversify and strengthen the electric power grid through the integration of cleaner energy sources such as wind and solar and by supporting local renewable energy generators and distributed renewable energy (DER) projects.<br />\n&nbsp;<br />\n[1] US EPA.

In the building sector, TES systems supply thermal energy for domestic hot water, space heating, and air-conditioning. The solar industry utilizes TES to store energy for concentrating solar power (CSP) plants, which use mirrors to focus sunlight and produce and store high-temperature thermal energy for electricity production in the absence of sunlight.[2]<br />\nThere are three kinds of TES systems:</p>\n<p>Sensible heat storage, which stores thermal energy by heating or cooling a liquid or solid storage medium (e.g., water, sand, molten salts, rocks).<br />\nLatent heat storage, which uses phase change materials or PCMs (e.g., from a solid state into a liquid state).<br />\nThermo-chemical storage (TCS), which uses chemical reactions to store and release thermal energy.[3]</p>\n<p>Sensible heat storage and latent heat storage are the most widely used for commercial building applications. Currently more complicated and cost prohibitive, future advances in thermochemical heat storage (THS) systems hold the potential for high storage density, low volume requirements, low heat loss, longer storage periods and low charging temperature.[4]<br />\nTES technologies for heating applications include electrical or solar thermal water heating systems that use hot water tanks to store water until it is needed. TES systems improve the energy efficiency of buildings and provide cost savings by storing waste heat or by-product heat when it is available and supplying it upon demand.[5] Typical independent parameters that characterize TES systems in use are shown in the below table.[6]</p>\n<p>TES technologies for cool storage include:</p>\n<p>Sensible heat storage systems, such as chilled water (CHW) TES, and low-temperature fluid (LTF) TES, which store thermal energy as a temperature change.<br />\nLatent heat storage systems, such as ice TES, which store thermal energy as a change of phase material (e.g., water to ice).</p>\n<p>How to Integrate a Thermal Energy Storage System<br />\nFirst, assess whether the building meets one or more of the following conditions for integrating TES: high utility demand costs, high peak-use utility costs, high daily load variations, short durations of loads, infrequent cyclical loads, and available incentives or rebates.[7]<br />\nNext, determine what type of TES system to install based on the building size and utility costs. Phase change TES system typically work for small buildings while larger buildings often utilize temperature change systems. For example, small commercial buildings with space constraints may want to consider ice storage systems designed with integrated roof-top mounted, direct-expansion cooling systems. For larger commercial buildings, think about a stand-alone water chiller system with high thermal storage capacity. TES technology also scales well to district energy systems that serve multiple buildings.<br />\nFinal steps include installation and monitoring performance to fine-tune the system and to calculate payback periods and cost-savings.<br />\nExamples<br />\nNREL’s Energy Systems Integration Facility (ESIF), Golden, CO.<br />\nThe Energy Systems Integration Facility (ESIF) at the US DOE’s National Renewable Energy Laboratory (NREL) houses a state-of-the-art high-performance computing data center built to LEED Platinum. Hot water loops harvest waste heat from the data center and provide heating for the offices and labs.[8] Data center waste heat also heats glycol loops located under the plaza and walkway, melting snow and improving walkway safety.[9]  Utility rebates supported building commissioning, performance verification, and system improvements.<br />\nTIAA-CREF, New York City, NY<br />\nThe Teachers Insurance and Annuity Association (TIAA) replaced an aging chiller system with a new rooftop, chilled water system for ice production that runs during off-peak hours and includes a 30-tank thermal storage system.<br />\nDurst Organization, New York City, NY<br />\nThe 41-story Durst Organization headquarters building uses off-peak, nigh-time electricity to make and store ice in 28 storage tanks located in the basement. Small pumps move ice-cooled fluid past fans that blow cold air into the building during daytime operations.<br />\nBenefits<br />\nThermal Energy Storage (TES) systems facilitate participation in demand response programs, reducing peak demand, energy consumption, CO2 emissions, and costs by utilizing less expensive, off-peak electricity and by increasing the overall efficiency of energy systems (see Demand Response and Peak Load Management). TES systems improve grid reliability by shifting peak heating and cooling loads from periods of high-demand to low-demand, eliminating the need for building new or maintaining older, less-efficient standby energy plants, and providing backup power to the grid like a generator and supporting distributed renewables generation.<br />\nCosts<br />\nTES saves money on electricity and maintenance costs depending on the design of the system, the cooling, and heating requirements of the space, and the time of day during which the storage unit uses energy for its operation. Ideally, TES systems remove thermal energy from the medium during off-peak periods and circulate it during periods of high heating and cooling demand.[10]<br />\nTES systems increase in effectiveness when existing electricity demands vary during the day, as the heat capacity of the medium enables the spreading out of electricity demands more than would be possible with a traditional cooling system. As a result, TES systems work most effectively in buildings experiencing peaks in electricity demands throughout the day and in a location with high peak rates for electricity.[11]<br />\nPrices vary depending on the type of TES system selected, variations in site-specific conditions and individual vendor offerings, but annual energy savings can offset the system costs within ten years.[12] Also, financing and incentives are sometimes available from utility companies to implement sizeable thermal energy storage systems. For example, the New York State Energy Research and Development Authority (NYSERDA) helped fund the TIAA-CREF building mentioned above.<br />\nWhile the cost-savings of shifting load to off-peak hours drives adoption of most TES systems, designs that reduce chiller size and cost and improve building system efficiency make TES systems for customers with a flat electricity rate a viable option as well.[13]<br />\nCheck with the New Jersey Clean Energy Program’s Combined Heat &amp; Power Program, Pay for Performance Program, and NJ SmartStart Buildings Programs for available incentives and rebates.<br />\nResiliency<br />\nTES systems offer a redundant building system for sustaining uninterrupted power in the event of a power outage. In the case of an emergency, TES systems provide a backup resource to supply heating or cooling to critical areas of a building. TES systems can complement traditional backup generation as part of an islandable microgrid and provide backup power during a grid outage or mechanical failure.[14] By contributing to the downsizing of chillers and HVAC equipment, TES systems reduce the stress on the grid during severe winter weather and heat waves, contributing to grid reliability. By shifting energy loads to off-peak hours, TES systems encourage the use of clean and renewable energy sources.<br />\n&nbsp;<br />\n[1] International Energy Agency Energy Technology Systems Analysis Programme (IEA-ETSAP) and International Renewable Energy Agency (IREA).

On-site renewable energy systems for existing commercial buildings include solar, wind, geothermal, and biomass. Electricity, heating, cooling, and other applications, including multi-purpose components can utilize renewable technologies. For example, installing solar photovoltaic (PV) panels on parking structures provides shading to cars and comfort to their occupants, while providing clean electricity.<br />\nMany locations – building and/or site — can use on-site renewable energy systems. The practicality of most renewable energy systems or combination of systems for a specific construction project increases when considered early in the planning stages of the site and building design, although retrofits also may be advantageous as illustrated in Figure 1.</p>\n<p>Implementation of Renewable Energy Systems<br />\nRenewable energy systems are complex and require project team members with on-site renewable energy system expertise. The US DOE’s Federal Energy Management Program’s Guide to Integrating Renewable Energy in Federal Facilities offers advice on understanding renewable energy options, selecting appropriate types of renewable energy technologies, and integrating these technologies into all project phases. For implementation in New Jersey, project teams should contact the NJ Office of Clean Energy to learn about current programs, tools, and available funding. Critical project-specific variables to consider include location, space, energy costs, available project incentives, local net metering and interconnection policies. Pre-implementation steps for an on-site renewable energy system project comprise preliminary screening, a renewable energy feasibility study, sizing and design of systems. [1]<br />\nOn-Site Renewable Energy Systems and Geothermal Systems<br />\nPhotovoltaics (PV)<br />\nPhotovoltaic (PV) systems refer to the use of renewable solar energy to create electricity. PV cells placed together in a module are grouped together electrically to form an array. Arrays of PVs applied to surfaces, such as a roof, capture light energy from the sun and produce electricity. The flexibility of installing this on-site renewable energy system makes it a suitable option for existing buildings. A specific PV system known as Building-Integrated Photovoltaic (BIPV)[2] uses PV technology and applies it to building materials, serving multifunctional purposes. For example, a BIPV skylight not only captures energy, generating electricity for a building, but also provides daylighting (see Daylighting). Another strategy incorporates PV technology into an exterior wall for decorative purposes as well as collecting energy.<br />\nNew Jersey has one of the fastest growing markets in PV technology.[3] The availability of PV combined with available incentives facilitates the design and installation of PV systems in New Jersey. While projects can tailor PV systems to meet the needs of a particular site and building, south facing surfaces not shaded by nearby trees, buildings, and structures provide the best results. If possible, orient collectors at the angle of the location’s latitude (in New Jersey, this is approximately 40°N).<br />\nGeothermal<br />\nGeothermal heat pumps (GHPs), also known as ground source heat pumps or geo-exchange systems, take advantage of the Earth’s relatively constant temperature (45°F- 75°F),[4] cooling buildings in the summer and warming them in the winter. Some geothermal systems have wells drilled vertically deep underground, while others have horizontal loops a shorter distance below ground.[5] ENERGY STAR qualified geothermal heat pumps use about 45% less energy than a standard heat pump.[6] Underground piping carries warranties of 25–50 years, heat pumps often last 20 years or more.[7]<br />\nWind Power<br />\nWind systems provide renewable energy in areas with sufficient wind speed. Prime locations for harvesting wind energy in New Jersey are along the shore. [8]<br />\nThe two main types of wind turbines include horizontal axis wind turbines (HAWT), the most common, and vertical axis wind turbines (VAWT).[9] Initially designed to be mounted on high poles in open or rural areas, small wind turbines (SWTs) include systems that are 100 kilowatts (kW) or less. Built-environment wind turbines (BEWT) refer to projects constructed on, in, or near buildings.[10] The highly turbulent and variable wind directions often found in the built environment make VAWTs a viable option as VAWTs do not need to orient into the wind to generate power.[11] VAWTs come in two different design types: the Savonius design, which generates power through drag, and the Darrieus, which generates power through an aerodynamic lift.[12]<br />\nSolar Thermal<br />\nSolar thermal, whether passive or active, utilizes solar power to heat water for domestic or process uses. Solar thermal water heating systems use tanks and solar collectors. Active water systems also use pumps and controls.  Three common types of solar collectors include flat-plate collectors, integral collectors, and evacuated tube collectors. Flat-plate collectors consist of insulated and weatherproof boxes with a dark absorber plate under glass or plastic covers that heats water. Integral collectors use the same system as a flat-plate collector, but the water continues on to a traditional hot water tank, ensuring a consistent supply of hot water. Evacuated tube collectors consist of rows of transparent tubes that allow water to pass through and heat quickly.[13]<br />\nBiomass<br />\nBiomass energy systems utilize biomass, a renewable resource, to power facility heating, electric power generation, or combined heat and power (CHP) systems (see Combined Heat and Power (CHP)).[14] Biomass sources include organic material such as plant matter, wood, waste wood, residue from agriculture or forestry and organic matter from municipal or industrial waste. Fumes from landfills such as methane, a natural gas, provide biomass for electricity generation.[15]<br />\nIn addition to purely biomass-powered electricity generation, consider biomass co-firing, applicable to commercial buildings that already have coal-fired boilers. Coal-fired boilers can handle a pre-mixed combination of coal and biomass. Alternatively, retrofit existing coal-fired boilers with a separate feed system for the biomass allowing biomass and coal to mix inside the boiler.[16]</p>\n<p>Examples<br />\nGeothermal: Atlantic County Utilities Authority (ACUA), Atlantic City/Egg Harbor Twp., NJ.<br />\nThe ACUA’s clean energy initiatives include a geothermal heating and cooling system at its GeoBuilding. The system depends on heating well water through fifty closed-looped wells on a field adjacent to the building. The system extracts heat from the water in the winter and transfers heat to the ground in the summer.<br />\nPV: Solar Islanding Project, Highland Park, NJ.<br />\nThis report analyzes the power demands and associated functions potentially sustained by three existing solar installations in Highland Park, NJ if converted into solar power islands. The report includes recommendations in language consistent with the National Incident Management System (NIMS) standard for adoption by other municipalities who may already have solar islands.<br />\nVineland Solar One, Vineland, NJ.<br />\nLocated on 14 acres at the Landis Sewage Authority (LSA), the Vineland Solar One generation facility includes 13,456 monocrystalline silicon panels that produce up to 5,500 MWh of energy annually. The NJ Office of Clean Energy Solar Renewable Energy Credit (SREC) Program and a Power Purchase Agreement between the Vineland Municipal Electric Utility (VMEU) and Conectiv Energy helped finance this public/private partnership.<br />\nWind: Jersey Atlantic Wind Farm, Atlantic City, NJ.<br />\nThe Jersey-Atlantic Wind Farm, a community-scale wind turbine installation, includes five, 380-foot turbines, producing a combined 7.5 megawatts of power. The wind turbines and on-site solar installation power the wastewater treatment plant, with surplus energy sent to the grid.<br />\nNREL. “Deployment of Wind Turbines in the Built Environment: Risks, Lessons, and Recommended Practices.”<br />\nThis study looks at several case studies of Built Environment Wind Turbines (BEWTs), documenting mixed-results in the BEWT industry. Main obstacles cited include, 1) insufficient and not well-defined project feasibility and planning processes, 2) high-cost projects related to additional expenses for installation and operations in the built environment, 3) a lack of certified manufacturers for ongoing service and parts, and 4) over-estimated project performance due to the complexity of conducting accurate resource and production assessments in the built environment. BEWT projects with the best outcomes had well developed and quantified project goals that included energy production as well as educational and sustainability marketing goals. These projects also conducted thorough feasibility investigations, used certified HAWTs with a proven track record, and were installed on tall buildings relative to surrounding obstacles.<br />\nSolar Thermal: Solar Water Heating in Multifamily Building, Greenfield, MA.<br />\nThe Consortium for Advanced Residential Buildings (CARB), a US DOE Building America team, installed a solar domestic hot water (SDHW) system (372 ft2 evacuated tub, 330 gallons storage) as part a major renovation project that converted an old school building into 12 high-performance apartments.<br />\nBiomass: Biomass Energy Resource Center (BERC)<br />\nWith funding from the US DOE, the Biomass Energy Resource Center (BERC) developed a series of 55 case studies illustrating the design and operational experiences of various community-scale facilities, including businesses, campuses, community buildings, schools, housing and government facilities, that employ biomass systems in the US, Canada, Europe, and Scandinavia.<br />\nThe Rex Lumber Company, Englishtown, NJ.<br />\nThe Rex Lumber Company, with a rebate for nearly 50% from the NJ Clean Energy Program, replaced a natural gas system with a wood-waste boiler biomass system to heat its kilns.<br />\nBenefits<br />\nIncorporating on-site renewable energy systems reduces greenhouse gas emissions, protects against the fluctuating costs of fossil fuels, and saves on purchasing energy from utility companies while providing additional ecological and user benefits as detailed below.<br />\nBiomass energy systems turn waste into resources, provide a renewable source of electricity and reduce the use of and dependency on fossil fuels, reducing greenhouse gas emissions and enhancing fuel supply security. Biomass powered CHP systems have the added benefit of generating both low-carbon electricity and low-carbon heat, further increasing energy efficiency and reducing carbon emissions by utilizing waste heat and using fuel more efficiently.[17] Biomass reduces waste management costs like tipping fees while promoting local business and farming. Replacing up to 20% of fossil fuel such as coal with bio-fuel also reduces nitrous oxides, carbon dioxide, and sulfur dioxide emissions. Capturing methane, a gas emitted by the decomposition of waste 28-36 times stronger than carbon dioxide, reduces emissions of a significant greenhouse gas.[18]<br />\nGeothermal pumps have a higher efficiency than air pumps and produce less noise pollution as most of the moving parts are underground. Depending on the cost and type of fuel, heating with geothermal pumps can cost 25-50% less than that of conventional heating.[19] Compared to air-source heat pumps, geothermal pumps last longer, require less maintenance and do not depend on outside air temperatures.[20]<br />\nThe modularity of PV systems allows great flexibility in applying this technology to buildings. Solar PV can help manage peak demand and lower utility rates, while also providing shade and urban heat island reduction benefits.<br />\nSolar thermal systems reduce water consumption as well as the consumption of consumable, non-renewable, and often non-domestic energy sources such as natural gas.[21]<br />\nWind power reduces dependence on carbon-intensive fuels such as coal.[22] Generating power from wind reduces greenhouse gas (GHG) emissions and promotes the renewable energy industry in New Jersey.<br />\nCosts<br />\nGeothermal – The capital cost of geothermal systems average $7, 000.00 per ton including the bore field.[23] Highly site-specific, well field costs can quickly add tens of thousands of dollars to overall system cost. Life-cycle costs can deliver a relatively quick payback beginning at 5 years, based on significant heating cost savings.[24] Annual energy savings can vary from 25% to 50%.[25] Also, maintenance and upkeep cost less than traditional types of heating and cooling equipment.</p>\n<p>Incremental cost (e.g., the cost of the green technology minus the cost of conventional technology) is around $3,957/ton.[26]</p>\n<p>Annual cost savings (e.g., annual kWh saved * $0.14/kWh [the price of electricity])<br />\nAccording to US DOE Energy Savers, using GHPs reduce electricity consumption by 25-50%.</p>\n<p>Scenario: Consider a 20,000 SF commercial building using 50,000[27] btu/SF over five years.<br />\nIn one year:     50,000btu/SF ÷ 5 years = 10,000 btu<br />\n10,000 btu/SF * 20,000 SF = 200,000,000 btu<br />\n200,000,000 btu * (2.93×10-4 kWh/1 btu) = 58,614kWh consumed.<br />\nA reduction in electricity consumption of 50% means a savings of 29,307 kWh, or:<br />\n29,307 kWh * $0.14/kWh = $ 4,102.98</p>\n<p>Payback (Capital Costs or Incremental Costs / annual cost savings)Incremental Cost = $3,957</p>\n<p>Annual Cost Saving =             $4,102.98<br />\n$3,957/$4,102.98 =                 0.96<br />\nIt will take less than one year to achieve a return on the investment in a geothermal heat pump.<br />\nPhotovoltaic – PV systems have medium to high first costs, but like geothermal systems, have a quick payback, facilitated by various incentives and renewable energy credits. The New Jersey Office of Clean Energy Solar Renewable Energy Certificate (SREC) program provides renewable energy credits (RECs) during the first 15 years of the system’s life. Credits accumulate whenever a solar installation generates 1000 kWh of electricity. Prices for SREC credits sold through the SREC tracking system vary due to supply and demand.[28] System costs vary depending on type of panel used, roof type, and size of the system. In New Jersey, a commercial system typically cost between $3 and $5 a Watt, including installation. [29] Recent SREC pricing information can be found here: http://www.njcleanenergy.com/renewable-energy/project-activity-reports/srec-pricing/srec-pricing<br />\nSmall Wind – Small wind installations cost about $800 to $1100 per kilowatt of generating capacity.[30] The price of a system varies depending on the size and details of the service agreement. Depending on the strength of the wind resource and the cost of the system, the typical paybacks range from 6-15 years.<br />\nSolar Thermal – The average price of solar thermal collector equipment varies depending on the type (low, medium, high temperature) and ranges from $1.94-$25.32 per square foot, averaging $7.01 per square foot.[31] The cost table below compares the average cost of solar thermal to conventional energy sources for 2017.</p>\n<p>New Jersey<br />\nElectricity<br />\nNatural Gas<br />\nSolar thermal</p>\n<p>Average Cost per kilowatt-hour in commercial and industrial sectors:<br />\n10.16-12.31¢[32]<br />\n9.05¢[33]<br />\n9.2-12¢[34]</p>\n<p>Biomass – The economics of biomass power generation depends on the availability of a predictable, local, sustainably-sourced, low-cost and long-term feedstock supply.[35] Differences in feedstock chemical composition impact the cost of the feedstock. For example, waste produced due to industrial processes can have a zero or even negative cost by avoiding waste disposal charges. Likewise, prices for dedicated energy crops can spike due to low productivity and high transportation costs. Lower cost options may include agricultural, and forestry residues collected and transported over short distances or available locally as a by-product.<br />\nThe wide range of bioenergy-fired power generation technologies translates into a broad range of installed costs. For example, installation costs for biomass heating plants average between $500 to $1500 per kW-thermal of installed heating rate capacity.[36] Installation for small-scale biomass electric plants typically cost between $3,000 to $4,000 per kW.[37]<br />\nFixed operations and maintenance (O&amp;M) costs, such as labor, scheduled maintenance, routine component or equipment replacement, and insurance for bioenergy power plants typically range from 2-6% of total installed costs per year, while variable O&amp;M costs average 0.005/KWh.[38]</p>\n<p>Resiliency<br />\nOn-site renewable energy systems promote resiliency in many ways. They tend to rely on site-based “fuel” and may island or operate independently from the power grid (see Solar Islanding and Microgrid Ready Solar PV, Energy Storage and Back-up Power Generation). For example, solar islanding and microgrid ready PV systems with battery storage combine the benefit of traditional PV systems, which avoid the use of fossil fuels, while also providing a resilient, local, and independent source of electric power during power emergencies and help to manage peak demand and lower utility costs throughout the year via demand response programs. By providing localized power generation, islandable PV systems increase energy efficiency by reducing transmission and distribution losses typical of centralized grid systems.[39] Unlike diesel and fossil-fueled generators, typically used only during emergencies, islandable PV systems with battery storage provide value throughout the year, do not require regular maintenance or refueling, and can provide emergency power for extended periods of time given available solar resources and adequate battery storage.[40] Some systems provide additional protection from flooding events, based on elevated installations, such as PV roof or pole-mounted systems.<br />\nFor recommendations on how to incorporate solar islanding capabilities into existing facilities, see the Highland Park Solar Islanding Project.<br />\nBiomass offers several resiliency benefits including the ability to stockpile fuel for emergencies.[41] Plans to recover, segregate, and process biomass fuel locally makes downed biomass from fallen trees and vegetation caused by storms and natural disasters a cost-saving resource rather than a post-disaster clean-up expense.[42] Making use of downed biomass also frees up time and money for other recovery efforts, while at the same time providing short to long-term backup power for critical infrastructure and emergency services.<br />\nBiomass energy systems with off-grid or islanding capabilities and thermal energy storage provide enhanced energy independence, security, and reliability in the event of natural disasters and security threats while also helping to manage peak demand and lower utility costs throughout the year via demand response programs (see Thermal Energy Storage, Battery Storage and Back-up Power Generation, Demand Response and Peak Load Management).[43] Biomass-fired CHP systems promote the renewable energy industry in New Jersey by utilizing renewable sources of fuel, providing backup power and balancing the supply and demand of electricity from variable renewables such as wind and solar.[44] A form of distributed energy generation, biomass-fired CHP systems support the development and integration of microgrids and the broader smart grid, which aims to diversify and strengthen the electric grid through better energy management and the integration of cleaner energy sources and energy storage.<br />\n&nbsp;<br />\n[1] US Dept of Energy’s (DOE) Federal Energy Management Program (FEMP).

In New Jersey, Hurricane Sandy exposed the vulnerability of generators, as the storm disrupted access to fuel and competing fuel demands from the transportation sector quickly depleted local fuel reserves.[2]<br />\nEnergy storage refers to storing energy for later use when it is needed, such as during a power outage, or for energy arbitrage storing low priced energy and using that energy during peak demand when prices climb.[3] The following categories highlight current and emerging energy storage technologies applicable to the building sector:[4]</p>\n<p>Solid State Batteries<br />\nFlow Solid State Batteries<br />\nFlywheels<br />\nCompressed Air Energy Storage<br />\nThermal (see Thermal Energy Storage)</p>\n<p>Backup power provides energy required for supporting critical building functions by utilizing stored electrical or thermal energy (energy storage) from on-site power generation systems with islanding (generating power when the electrical grid is down) capabilities, or power from local microgrids and distributed energy generators. Energy storage systems could also help provide grid stabilization functionalities such as Contingency Reserve and Frequency Regulation.<br />\nAs the costs of energy storage and backup power generation systems continue to decline and the integration of these technologies continues to advance, several viable options exist for supplementing or replacing traditional standby generators, including:[5]</p>\n<p>Islandable Photovoltaics (PV) systems with battery storage (see Solar Islanding and Microgrid Ready Solar PV)<br />\nCombined Heat and Power (CHP) systems with or without energy storage (see Combined Heat and Power (CHP) and Thermal Energy Storage)<br />\nFuel Cells and hydrogen storage[6]<br />\nVehicle-to-Grid (V2G) Technology and battery storage (see Alternative Transportation)[7]</p>\n<p>How to Implement Energy Storage and Back-up Power Generation<br />\nFirst, analyze power demands and associated functions that would benefit from backup power in the event of power outage.<br />\nDistinguish between critical loads, such as providing basic heating and ventilation, cooking and food storage, emergency and night-time lighting, water pumps, and phone or laptop charging, and online access via a cable modem or wireless router versus non-critical loads such as full-capacity heating and ventilation, lighting, cooking, refrigeration, and television or other electronic entertainment and devices.[8] Figure 1 shows considerations for sizing solar and battery storage for backup power generation.<br />\nCritical project-specific variables to consider include location, space, energy costs, available project incentives, local net metering and interconnection policies. Note that configuring power systems to operate independently of the grid requires investments in additional hardware and software components, including transfer switches, inverters, critical load panels, energy storage, and appropriate controls to allow successful islanding to take place.[9]<br />\nAs per the Insurance Institute for Business and Home and Safety’s (IBHS) FORTIFIED Commercial Hurricane Standard, locate electrical connections for backup power generation and energy storage at an elevation above the 500-year flood level or 3 ft above the Base Flood Elevation (BFE) for the property or provide dry flood protection such as flood gates, walls or doors, inflatable barriers, or sand bags to prevent water intrusion.[10]<br />\nAccounting for cost savings during regular business operations (demand response) and for the cost of electric grid power outages and lost business (resiliency benefit) lowers the payback period for energy storage and backup power investments.[11]<br />\nContact the NJ Office of Clean Energy to learn about current programs, tools, and available funding.<br />\nExamples<br />\nPV and Battery Pilot Project, Hopewell Valley Central Highschool, Pennington, NJ<br />\nAs part of PSE&amp;G’s Solar 4 All Program, which supports solar technologies that also contribute to grid resiliency, the Hopewell Valley Central Highschool installed an 876 kilowatt-dc rooftop solar and parking lot solar canopy system with large lithium ion batteries.[12] The system can connect to the grid or charge batteries, allowing the highschool to participate in the PJM Frequency Regulation Market. During power outages, the system provides critical functions including heating/cooling, emergency lighting, and food refrigeration.<br />\nGAF Headquarters Building, Parsippany, NJ.<br />\nThe GAF Headquarters Building led the way in 2016 becoming the first building to ever be awarded the LEED pilot credit for resilient design (now being incorporated into the RELi resilience standard).[13] The project team designed the building to maintain critical functions in the event of a hurricane, by avoiding flood zones, designing flood preparation and backup capabilities for long-term power outages, reinforcing roof structures to hurricane wind standards, and developing a business continuity recovery plan that details employee and business procedures in the event of a disaster.<br />\nBenefits<br />\nOn-site energy storage and backup power generation provides a resilient, local, and independent source of electric power during power emergencies while also helping to manage peak demand and lower utility costs throughout the year via demand response programs (see Demand Response and Peak Load Management, and Smart Metering). For example, energy storage systems provide a way for customers to shift power demands to off-peak hours and to take advantage of time-of-day pricing and lower energy prices.<br />\nPV systems with solar islanding capabilities and battery storage combine the benefit of traditional PV systems, which avoid the use of fossil fuels, with the added benefit of increased power reliability. Battery storage helps to reduce common challenges with PV systems such as ramping, output variability, voltage and current inconsistencies that impact power quality, and a disconnect between the power supply (morning sun) and power demand (afternoon and evening air conditioning spikes).[14] Islandable PV systems with battery storage also provide value throughout the year, do not require refueling and can provide emergency power for extended periods of time given available solar resources and adequate battery storage.[15]<br />\nCHP systems that utilize both thermal and electrical storage further increase energy efficiency by capturing wasted energy resulting from the overgeneration of heat and electricity.[16] A form of distributed energy generation, CHP systems support the development and integration of the broader smart grid by providing a consistent and reliable source of backup power that helps to balance the supply and demand of electricity from other distributed energy generators, including variable renewables such as wind and solar.[17] Typical cost savings and project cost associated with CHP applications can be found on the DOE IAC database.[18]<br />\nFuel cells offer a clean, energy-efficient, grid-independent and reliable source of power provided adequate fuel supply from a variety of domestic energy sources such as hydrogen, natural gas, and methanol making them a viable alternative for backup power generation and storage.[19] Excess electricity produced by fuel cells can run an electrolyzer and extract hydrogen from water, providing hydrogen for storage and for later use in the fuel cell to produce electricity when it is needed.<br />\nVehicle-to-grid applications with bi-directional electric-plug in charging stations enable fully charged EV’s to supply power to the grid during emergencies or supply shortages.[20]<br />\nCosts<br />\nCompared to traditional power generation systems, islandable systems with energy storage require additional hardware and software components, electrical design and permitting requirements, and safety considerations, which translate into higher costs.[21] As the cost of energy storage and backup power generation technologies decline and power outages become more common, the cost savings from participation in demand response programs, and the resiliency benefits of avoided power outages, such as reduced business closures, health and safety hazards, food spoilage, and inconvenience from schedule disruptions, can offset the incremental costs. [22]<br />\nResiliency<br />\nEnergy storage and backup power generation support energy resiliency in many ways. Backup power generation systems that utilize energy storage or islanding and microgrid ready capabilities can operate independently from the grid during outages or at times of system peak and increase grid reliability by managing system outages and peak demand. Separation from the electricity grid also offers protection from security threats. Energy storage and backup power generation allow customers to take full advantage of demand response programs that signal when to use, store, or sell energy back to the grid and encourage electric vehicle charging during off-peak, low-cost hours or charging back to the grid during periods of peak demand.  Likewise, energy storage and on-site backup power help to support the development of the broader smart grid by providing a local, distributed energy resource and helping to manage the integration of clean and renewable energy to the grid.<br />\n&nbsp;<br />\n[1] New Jersey Climate Adaptation Alliance, Understanding New Jersey’s Vulnerability to Climate Change. http://njadapt.rutgers.edu/docman-lister/working-briefs/75-nj-vulnerabilities/file<br />\n[2] E.

An increase in extreme weather events, such as major hurricanes, thunderstorms, ice storms, and flooding in New Jersey has highlighted the importance of having access to clean and safe water to meet drinking, sanitation and hygiene needs during and after natural disasters, extended power outages, and other emergencies. For example, flooding can overwhelm municipal water and wastewater treatment plants and storm-related power outages can impact plant operations. Flood waters can contaminate local water supplies and private wells with raw sewage and stormwater runoff containing chemicals, debris, and other contaminants that can cause serious illness.[2] While backup generators at municipal water and wastewater treatment plants can prevent power outages and elevating equipment can protect plant operations, individual building owners and operators can also take steps to safeguard water for emergencies.<br />\nStrategies to safeguard water at the building level include designating back-up power for water pumps, providing on-site water storage, and designing redundant water supply and treatment systems that utilize captured rainwater or recycled wastewater as the primary or backup water supply (see Rain Barrels and Cisterns, and On-site Alternative Water Reuse).<br />\nHow to Provide for Emergency Water Supply and Storage<br />\nPlanning for access to potable water during a power outage or storm-related event, starts with water conservation, and can include reusing water on-site, such as harvested rainwater or recycled greywater for storage and later use during emergencies to cover operations such as toilet flushing, mechanical equipment, and irrigation (see Water-Efficient Landscaping, Indoor Water Conservation, On-site Alternative Water Reuse).<br />\nThe specifics depend on whether or not the building utilizes the municipal water system. During a water emergency, a building on municipal water may still have access to clean potable water due to the municipal water and treatment plant’s backup water storage or backup power system.[3] In this situation, planning for emergency water supply and storage requires providing backup power generation to operate water pumps and to distribute water throughout a building (see Energy Storage and Back-Up Power Generation).<br />\nBuildings with deep-well pumps that do not rely on the municipal water supply can utilize energy storage and back-power generation, or hand pumps to power the deep-well pump. Gravity-fed water from an on-site spring or cistern part of a rainwater harvesting system, which includes adequate water storage can provide a redundant or backup water supply to complement public or deep-well water resources. Where there is no option for on-site water replenishment, look to provide emergency water storage that can gravity-feed water to the building, such as rooftop water tanks or water storage with pumps powered by stored energy or off-grid generators.<br />\nExample<br />\nStony Brook-Millstone Watershed Association Center<br />\nRainwater collected from the building’s rooftop supplies water for flushing toilets, reducing municipal potable water, stormwater runoff, and energy used to pump and treat water.<br />\nBenefits<br />\nThe benefits of planning for emergency water supply and storage become most apparent during an emergency or disaster. Proper preparations can reduce business closures and avoid health and safety hazards associated with water emergencies. Planning for access to potable water during emergencies can also benefit overall water conservation efforts during normal operations, as alternative solutions and reuse scenarios are considered to utilize and manage water on a site.<br />\nCosts<br />\nThe rising cost over the last decade of water and wastewater services can make minor investments in water conservation strategies and back-up technologies cost-effective based on the savings alone from reduced water bills.[4] Factoring in savings from reduced energy bills further reduces payback periods. As the cost of water storage and backup power generation technologies decline and power outages and water emergencies become more common, the resiliency benefits of reduced business closures, health and safety hazards, and inconvenience from schedule disruptions, can offset the incremental costs. [5]<br />\nResiliency<br />\nProviding for emergency water supply and storage enhances resiliency by utilizing redundant and local water supplies and reducing impacts from droughts and other instances of water scarcity. Ensuring access to potable water during emergencies decreases the reliance and stress on the entire municipal water infrastructure including groundwater pumping, and water and wastewater treatment and distribution, reducing the likelihood of system overload and failure.[6]<br />\n&nbsp;<br />\n[1] New Jersey Department of Environmental Protection, 2017, New Jersey Water Supply Plan 2017-2022: 484p, http://www.nj.gov/dep/watersupply/wsp.html (accessed Oct 25, 2018).<br />\n[2] Center for Disease Control and Prevention. 2018.

Storm preparation and emergency planning includes steps that residents and businesses can take to avoid or mitigate impacts and increase safety and comfort before, during and after adverse events. Proper preparation and planning also refers to resilient design and green building practices that increase a structure’s ability to withstand or recover from severe weather and adverse conditions and protect building occupants. For example, at the building owner level, the Federal Emergency Management Association (FEMA) recommends securing property to protect against hurricane damage by:</p>\n<p>Installing permanent storm shutters for windows or boarding up windows with 5/8” plywood, cut to fit and ready to install.<br />\nAdding straps or clips to securely fasten roof to the frame structure and reduce roof damage.<br />\nClearing loose and clogged rain gutters and downspouts.<br />\nBringing in outdoor objects such as furniture, equipment and tools or anchoring them if they cannot be brought indoors.</p>\n<p>At the design and building level, the FORTIFIED Building Standards by the Institute of Business and Home Safety (IBHS) recommend roofing and fenestration best practices to protect buildings in hurricane prone areas and areas susceptible to hail and high winds. Together, these precautions provide redundancy and increase the likelihood of avoiding major damages and injuries.<br />\nFor more information on hurricane preparedness, see the New Jersey Office of Emergency Management (NJOEM) and the NJ Hurricane Survival Guide.<br />\nHow to implement Storm Preparation and Emergency Preparedness<br />\nA number of local, state and national organizations provide resources and information on storm preparation and emergency preparedness (see Resources below). The NJOEM’s “Be Ready: Follow the “Three Steps to Safety” outlines basic preparations for the most common disaster scenarios in New Jersey.<br />\nStep One: “Get a Kit” – Assemble emergency supplies including food, water, basic first aid supplies, alternative communication and other emergency equipment such as flashlights and duct tape. See Ready.gov “Build a Kit.”<br />\nStep Two: “Make a Plan” – Know your area’s evacuation routes and shelter locations. Keep a list of emergency contacts and local emergency numbers. Visit the American Red Cross Ready Rating web page for more information.<br />\nStep Three: “Stay Informed” – Part of preparation is knowing exactly what kind of disasters you might face and knowing what to do in each situation. Keep track of Current Weather Forecasts and Alerts with:</p>\n<p>Local radio or TV stations<br />\nNOAA Weather Radio– or listen online<br />\nNJOEM’sWeather Links</p>\n<p>Benefits<br />\nUsing resilient building practices and developing emergency preparedness plans and supply kits:</p>\n<p>Reduces fear, anxiety, and losses.<br />\nAvoids or mitigates impacts and costs.<br />\nSpeeds recovery efforts and reduces further damage and losses.</p>\n<p>Costs<br />\nStorm preparation and emergency planning can reduce severe weather and disaster-related costs by reducing the physical and financial toll from such events. For example, identify vulnerabilities that offer the greatest potential to reduce avoidable suffering.<br />\nResiliency<br />\nHaving a plan in place and supplies on hand for common emergencies and disasters helps to avoid or mitigate potential impacts and to support recovery efforts. Prepared individuals and businesses can react quickly and safely to situations, reduce stress on local emergency responders and resources, and support local community outreach.</div>\n			</div>\n			</div><div class=\"et_pb_column et_pb_column_1_3 et_pb_column_5  et_pb_css_mix_blend_mode_passthrough et-last-child\">\n				\n				\n				\n				\n				<div class=\"et_pb_module et_pb_text et_pb_text_7  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				<div class=\"et_pb_text_inner\">Related Strategies</p>\n<p>Emergency Water Supply and Storage<br />\nEnergy Storage and Back-up Power Generation<br />\nSolar Islanding and Microgrid-Ready Solar PV</div>\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_8  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				<div class=\"et_pb_text_inner\">Resources</p>\n<p>American Red Cross Ready Rating<br />\nBe Ready Campaign<br />\nCenter for Disease Control and Prevention – Center for Preparedness and Response<br />\nFederal Emergency Management Association (FEMA)<br />\nInstitute for Business and Home Safety<br />\nOpen for Business (OFB-EZ)<br />\nEmergency Preparedness and Response Planning (EZ-Prep)<br />\nFORTIFIED Commercial Building Standards<br />\nState of New Jersey Office of Emergency Management<br />\nRELi 2.0 Rating Guidelines for Resilient Design + Construction – HP: Hazard Preparedness</div>\n			</div>\n			</div>\n				\n				\n				\n				\n			</div>\n				\n				\n			</div></p>\n'),(9183,2007,'_et_pb_truncate_post_date','2022-05-26 00:21:21'),(9184,2007,'_et_pb_old_content',''),(9186,170,'_wp_attachment_image_alt','Figure 1-Simple schematic design for rain barrels (Source: Low Impact Development Center)'),(9187,517,'_wp_attachment_image_alt','Fig 1 – New Jersey’s tropical storm activity is typically between August and late October.

Observe the site during the next rain and note where runoff problems exist. Consider the following:</p>\n<p>Does it come from a roof or downspout?<br />\nIs there runoff from the driveway?<br />\nDoes the runoff gravitate towards one place more than another?</p>\n<p>Work with landscape architects to incorporate a rain garden early in the design process. As a general rule of thumb, place the rain gardens at least 10 feet from building foundations if the structure has a basement; for residences without basements, place rain gardens at least 2 feet from the home.[1]<br />\nFor step-by-step guidance on installing a rain garden, see The Rutgers Water Resources Program and the Native Plant Society of New Jersey’s Rain Garden Manual of New Jersey.<br />\nExamples<br />\nNew Jersey Demonstration Rain Gardens<br />\nThe Rutgers NJ Agricultural Experiment Station’s Water Resources Program has installed over 125 demonstration rain gardens in New Jersey.<br />\nBenefits<br />\nOn average, New Jersey receives 44 inches of rain per year, which flows untreated into storm drains and local water bodies resulting in pollution and poor water quality.[2] Rain gardens provide a low-cost, low-tech method for reducing the amount of runoff that enters streams and rivers.<br />\nReduced stormwater runoff and increased groundwater recharge – As stormwater runoff flows into rain gardens, much of it is absorbed back into the soil, increasing groundwater recharge and reducing runoff into storm drains and waterways (see Pervious Paving Materials).<br />\nFiltering and cleaning water before it enters storm drains – Plants in rain gardens filter stormwater, improving water quality and allowing sediment to settle out instead of clogging storm drains.<br />\nHabitat Creation and Increased Amount of Native Vegetation – Rain gardens designed with native plants increase biodiversity and provide habitat for birds, butterflies, and other wildlife and provide opportunities for views and connection with nature (see Biophilic Design, Wildlife Habitat, and Sense of Place).<br />\nCosts<br />\nThe cost for a residential-size rain garden ranges from $3-5 per square foot, depending on existing soil conditions, selection of plants, and whether or not a homeowner chooses to hire professional labor or to complete the project on their own.[3]<br />\nSee the Rain Garden Cost Calculator to estimate costs based on the size and selection of plants for a typical residential rain garden in the Northeast.<br />\nResiliency<br />\nGreen infrastructure such as rain gardens integrates resilient and green design to complement and reduce reliance on traditional grey infrastructure. For example, rain gardens help to increase stormwater infiltration, reducing stress on municipal sewer systems during heavy rain events and help to recharge groundwater during periods of drought. Rain gardens support ecological resilience by increasing the biological diversity of native plants and animals in a given area, which in turn, enhances the ability of the natural system to rebound after a disturbance.<br />\n&nbsp;<br />\n[1] The Rutgers Cooperative Extension Water Resources Program and the Native Plant Society of New Jersey’s Rain Garden Manual of New Jersey http://water.rutgers.edu/Rain_Gardens/RGWebsite/RainGardenManualofNJ.html (accessed April 2, 2018).<br />\n[2] Rutgers NJAES. “Rain Gardens Fact Sheet: Rain Gardens.” http://water.rutgers.edu/Rain_Gardens/fs513.pdf (accessed March 25, 2018).<br />\n[3] Sustainble Jersey. 2017.

water quality by utilizing landscape designs and plantings suited to local conditions.  Most water efficient landscaping approaches incorporate the following suggestions:[2]</p>\n<p>Group plants according to their watering needs.<br />\nUse native and adapted plants (see Native and Adapted Plants).<br />\nLimit turf areas (see Turf Grass Reduction).<br />\nUse efficient irrigation systems and watering schedules (see Smart Sensors and Controls).<br />\nStart with healthy soil and add mulch to retain moisture.<br />\nProvide regular maintenance.</p>\n<p>The US EPA estimates that the average family of four uses about 400 gallons of water per day, 30 percent for outdoor use. Landscape irrigation accounts for more than one-third of all residential water use nationwide. Water use depends on location and climate, but in some areas, up to 50 percent of water used to irrigate may be lost to evaporation, wind, and improper system design or overwatering.[3] Minimizing or eliminating the use of potable water for irrigation can conserve clean water for the benefit of the environment and the community.</p></div>\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_16  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_17  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				<div class=\"et_pb_text_inner\">How to Implement Water-Efficient Landscapes<br />\nDesign landscapes that rely on natural rainfall and only require supplemental irrigation during the plants’ initial establishment period. Use native and appropriate non-native vegetation adapted to site conditions and climate (see Native and Adapted Plants). Group plants with similar water requirements to maximize irrigation efficiency and use climate-based controllers for irrigation systems to lower water consumption. Consider using non-potable water for irrigation (see Rain Barrels and Cisterns, and Onsite Alternative Water Reuse).[4]<br />\nFor more information, refer to US EPA’s WaterSense Water-Smart Landscaping Design Guide.<br />\nFor location specific information, refer to your county extension service, and local garden and nursery centers.<br />\nBenefits<br />\n Economic:</p>\n<p>Lowers water bills – careful design and choice of appropriate plants can reduce outdoor water use by 20 to 50 percent.[5]<br />\nIncreases home values – attractive, water-efficient landscaping may increase property values.<br />\nSaves money spent on landscape maintenance because many water-efficient plants require less care.<br />\nReduces tax burden by reducing stress on the municipal water infrastructure.</p>\n<p> Environmental:</p>\n<p>Conserves natural resources.<br />\nProtects against habitat loss and increases biodiversity by introducing native plants<br />\nLowers energy use due to less pumping and treatment of water.<br />\nReduces stormwater and irrigation runoff that transport top soils and pollutants into waterways.</p>\n<p>Personal Wellness:</p>\n<p>Saves time spent on landscaping.</p>\n<p>Costs<br />\nThe cost of water-efficient landscaping does not exceed the cost of conventional landscaping. The cost and cost-savings of water-efficient landscaping vary depending on the local cost of water. Converting irrigated turf lawns to ground covers or mulched areas can result in considerable cost savings. Changing watering schedule and landscape management without making any physical changes in the landscape may save water. A study by the UGA Cooperative Extension notes that converting 1,000 square feet of irrigated area to a non-irrigated area may save up homeowners an estimated minimum of $60 per year.[6]<br />\nIncentives for homeowners may be available through the US EPA’s WaterSense program. The program assists homeowners in improving water efficiency and reducing costs by promoting efficient irrigation technologies such as weather-based irrigation controllers and soil moisture sensors.<br />\nResiliency<br />\nWater-efficient landscaping increases resiliency by decreasing the reliance and stress on municipal water infrastructure and supply, and by supporting local ecosystems that are drought tolerant (see Emergency Water Supply and Storage).<br />\n&nbsp;<br />\n[1] US EPA.

A space with excellent acoustics has a minimal echo and controls excess noise from outside sources as well as sources within the building.[1] Three common noise issues include excess noise from outside, noise from adjacent spaces, and noise control issues within a space.[2] Controlling these aspects of sound can help improve indoor environmental quality (IEQ).[3] Achieving a high level of indoor environmental quality is an important component of residential construction. Adopting sound absorbing materials can enhance indoor acoustics and provide a better quality of life for building residents.[4]</p></div>\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_11  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_12  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				<div class=\"et_pb_text_inner\">How to Improve Acoustic Comfort<br />\nReduce unnecessary noises originating from poor insulation by implementing high Sound Transmission Class (STC) walls between high noise areas inside and outside the building. STC is a numerical rating system that measures the ability of a wall, floor, window, or ceiling to minimize sound transmission. Hire an acoustical engineer to achieve the ideal acoustical conditions.[5]<br />\nNoises can also originate from too much reverberation (sound reflecting off various surfaces). Reverberation can be addressed by strategically installing acoustic materials that either absorb or diffuse noise. For example, soft padded furniture helps reduce reverberation and absorb unnecessary noises. It is also worth considering the option of installing carpet or utilizing area rugs in large open areas. In contrast to hard flooring materials such as tile and wood, carpet is particularly effective at reducing noise caused by reverberation.[6] When choosing carpets and rugs, make sure to select eco-friendly products that are made with natural fibers or recycled material and do not compromise the indoor environmental quality (see Sustainable Materials).<br />\nExtraneous and distracting indoor noises may also stem from household heating and cooling equipment. Mechanical equipment such as a building’s HVAC system can become too noisy and undermine indoor comfort.[7]<br />\nAn integrated design process is key to achieving a high level of acoustic comfort. Project goals related to security and sustainability, for example, are sometimes perceived to conflict with acoustic goals but involving professionals from those areas of expertise from the start of the project, helps achieve synergistic goals.[8]<br />\nBenefits<br />\nAcoustic comfort can reduce stress, protect the health, and increase occupant satisfaction and productivity by contributing to a more comfortable environment psychologically and acoustically. Sound absorbent materials are especially beneficial in multi-family units to reduce adjacent noises from neighbors.<br />\nCosts<br />\nThe cost of implementing strategies to achieve acoustic comfort varies depending on specific project goals and the approach taken. In general, doors, windows, and walls with higher STC ratings are usually more expensive than their traditional counterparts. A primary reason for added costs is that higher-rated STC products typically contain more materials, such as drywall, insulation, and studs. However, a higher STC rating can be achieved in numerous ways, from merely using thicker drywall or increasing the density of insulation, to utilizing specialized products such as soundboards and sound absorbent foams and glues.[9] Overall, costs are primarily dependent on the construction methods and materials utilized to achieve a higher STC rating.<br />\nResiliency<br />\nAcoustic comfort is a critical element of indoor environmental quality (IEQ) that affects the health and well-being of building occupants. In the event of a disaster or emergency, a high-quality indoor environment helps protect building occupants and contribute to a built environment that can provide protection and recovery from hazardous events.<br />\n[1] GSA.

These substances degrade indoor air quality by exposing building occupants to various irritants. Entryway systems, such as mats, improve IAQ by catching and holding dirt particles and thereby reduce the amount of dirt that enters a dwelling.</div>\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_6  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_7  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				<div class=\"et_pb_text_inner\">How to Incorporate Entryway Systems<br />\nPlacing doormats at outside entrances help prevents dirt from entering the residence.

Individual comfort levels vary due to differences in clothing, activity level (metabolic rate), and individual preferences.[1]  Temperatures in residential buildings tend to fluctuate considerably in comparison to commercial buildings.[2] Time of day, type of room (kitchen, bathroom, bedroom), open windows, and what a resident is wearing, eating and drinking, affect what temperature is necessary for optimal comfort.<br />\nASHRAE Standard 55, Thermal Environmental Conditions for Human Occupancy aims to satisfy most of the people, most of the time and combines four of the traditional comfort factors (air temperature, air humidity, radiant temperature, and airspeed) to define comfort ranges for occupants. Satisfying the people who fall outside ASHRAE’s standardized comfort bands requires individualized comfort controls.[3] ASHRAE Standard 55 specifies conditions for thermal comfort for occupants of buildings, including residential buildings.[4] ASHRAE Standard 62.2 is a residential ventilation standard for buildings 3 stories and less.[5]<br />\nHow to Implement Individual Comfort Controls<br />\nASHRAE Standard 55 identifies the factors of thermal comfort and a process for developing comfort criteria. Control strategies can expand beyond basic comfort criteria and allow adjustments to suit individual needs and preferences. For example, individual comfort controls can involve system designs incorporating operable windows, hybrid systems integrating operable windows and mechanical systems, or mechanical systems alone (see Natural Ventilation, Energy-Efficient Windows, and Views and Operable Windows).[6] Individual adjustments may involve individual thermostat controls, local diffusers at the floor, desk or overhead levels, or control of individual radiant panels, or other means integrated into the overall structure, thermal comfort systems, and energy systems design (see Smart Sensors and Controls, Glare and Heat Gain Reduction and Daylighting). Individual comfort controls can also refer to lighting controls and automatic daylighting systems and provide occupants with the ability to adjust lighting levels and reduce glare through task lighting or operable shading devices (see Daylighting, and High-Efficiency Lighting Systems and Networked Lighting Controls).<br />\nExample<br />\nResidence Hall at Roanoke College<br />\nA residence hall at Roanoke College in Virginia earned LEED certification and featured rooms with natural lighting and individual controls along with other energy efficiency strategies and sustainable materials.</div>\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_1  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_2  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				<div class=\"et_pb_text_inner\">Benefits<br />\nIndividual comfort controls:[7]</p>\n<p>Improve thermal comfort for individual occupants.<br />\nImprove air movement and ventilation effectiveness; a cleaner environment.<br />\nImprove task lighting and reduce glare and heat gain.<br />\nReduce building energy use.<br />\nLower building operating costs.<br />\nImprove occupant satisfaction.</p>\n<p>Costs<br />\nThe cost of implementing a system that allows for individual comfort controls vary by project but is usually most cost-effective when incorporated through an integrated design process (see Integrated Design Process). Often viewed as a soft or intangible benefit, incorporating energy efficient systems can increase thermal comfort and reduce costs.[8] For example, a programmable thermostat is estimated to save 10% per year on heating and cooling costs.[9]<br />\nResiliency<br />\nIf the power does not go out during emergencies and severe weather events, occupants can maintain control of the temperature and ventilation of specific areas within a building with individual controls, thus improving comfort. Individual comfort controls can decrease overall energy use and improve occupant comfort, health, and well-being, all of which can contribute to resiliency through helping occupants and communities withstand and recover from disruptions.[10]<br />\n&nbsp;<br />\n[1] UC Berkeley. Thermal Comfort in UFAD Systems. http://www.cbe.berkeley.edu/underfloorair/thermalcomfort.htm (accessed September 10, 2018).<br />\n[2] Leen Peeters, “Thermal Comfort in Residential Buildings: Comfort Values and Scales for Building Energy Simulation.” Applied Energy 86-5 (2009).<br />\n[3] ASHRAE Standard. Thermal Environmental Conditions for Human Occupancy. https://www.ashrae.org/technical-resources/bookstore/standard-55-thermal-environmental-conditions-for-human-occupancy (accessed September 10, 2018).<br />\n[4] Bean R.E, T., P.L., Robert and Rodrigo Mora. “Prioritizing Thermal Comfort for Homes.” ASHRAE Journal 60-9 (September 2018) https://commons.bcit.ca/besys/files/2018/09/Prioritizing-thermal-comfort-for-homes-Bean-Mora-ASHRAE-Journal-September-2018.pdf (accessed January 27, 2019).<br />\n[5] Berkeley Lab.

Excess moisture is at the center of many problems related to building durability and indoor air quality in all types of buildings in a wide range of climates. Excessive moisture in buildings can result from many causes: [1]</p>\n<p>Rainwater leaks through roofs and walls<br />\nLeakage of moist air<br />\nDiffusion of moisture through walls, roofs, and floors<br />\nGroundwater intrusion into basements and crawl spaces through walls and floors<br />\nLeaking or burst water pipes<br />\nIndoor moisture sources<br />\nConstruction moisture</p></div>\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_19  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_20  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				<div class=\"et_pb_text_inner\">Moisture problems can lead to the growth of mold and mildew; individuals with allergies and other respiratory issues can be sensitive to mold and mildew spores in the air. Mold and mildew are part of the natural environment and are present in the air; however, they become an issue when their concentrations become high. It is challenging to prevent any mold or mildew growth, or to eliminate it; however, it is possible to control their presence within acceptable limits. In addition to mold, other microorganisms (e.g., bacteria), as well as pests (e.g., mites, cockroaches, and insects) that are known to infest buildings also depend on moisture to survive. Excessively high moisture content in thermal insulation can also reduce the effectiveness of insulation by as much as 50%.[2] Implementing moisture control can both protect structures from rot and deterioration and protect occupants from exposure to mold and bacteria.[3]<br />\nAccording to the US Environmental Protection Agency, the following are primary causes of indoor moisture problems in new buildings:[4]</p>\n<p>Use of building materials that are repeatedly or deeply wetted before the structure. is fully enclosed.<br />\nPoor control of rain and snow resulting in roof and flashing leaks.<br />\nWet or damp construction cavities.<br />\nMoisture-laden outdoor air entering the structure.<br />\nCondensation on cool surfaces.</p>\n<p>How to Implement Moisture Control<br />\nProper construction of the envelope to reduce the migration of warm and humid air from entering the wall and other cavities is critical for controlling moisture. The envelope is the physical barrier between indoors and outdoors that encloses the structure, including the foundation, roof, floor, ceiling, and walls.[5] Specific recommendations include proper use of vapor retarders on the warm, humid side of the insulation, using vapor barriers to isolate concrete slabs from moist soil, adequate ventilation of areas where moisture can accumulate, and ensuring proper flashing around windows, rooflines, and capillary breaks on footings.<br />\nKey strategies for reducing moisture in new construction include:[6]</p>\n<p>Keeping construction material dry before installation (and drying any materials that get wet within 24-48 hours).<br />\nDesigning roof systems that prevent the accumulation of moisture from rain and snow from penetrating roof surfaces.<br />\nEnsuring fresh air intakes for ventilation system have outwardly sloped louvers to reduce the introduction of water during rainfall.<br />\nGrading the soil around the residence to move water away from the structure, reducing moisture seepage into foundation walls, and avoiding the addition of large areas of impervious surfaces (which can increase the cost and size of stormwater management systems).<br />\nIncorporating covered entryways to reduce moisture introduction during wet weather.<br />\nRight-sizing HVAC systems so that they operate long enough to reduce airborne humidity.<br />\nUsing dehumidifiers.<br />\nInsulating ductwork, refrigeration and water lines to minimize condensation problems.</p>\n<p>Example<br />\nThe Harrison Residence, Westfield, NJ<br />\nThis residential project achieved LEED for Homes Gold certification and included an excellent indoor environmental score in part due to comprehensive HVAC design that included moisture control measures.<br />\nBenefits</p>\n<p>Increases the longevity of the structure, materials, and systems<br />\nReduces the costs of replacing or repairing materials and systems<br />\nProtects the health of building occupants<br />\nReduces life-cycle costs</p>\n<p>Costs<br />\nIn addition to contributing to poor indoor air quality, excessive moisture can lead to structural damage, deterioration of the performance of building systems and components, and cosmetic damage, all of which can result in increased maintenance and repair costs. Designing for effective moisture management protects occupant health and can lower facility maintenance costs over the lifetime of the structure.[7]<br />\nResiliency<br />\nStrategies such as complete waterproofing up to the design flood elevation, using moisture protective and inherent moisture-wicking materials, as well as materials resistant to excessive humidity such as glazed brick, concrete, stone, and decay-resistant lumber can all contribute to more resilient structures. Incorporating moisture control measures such as these into new construction can help develop a built environment that endures and recovers from hazardous events such as storms and flooding.[8]<br />\n&nbsp;<br />\n[1] Whole Building Design Guide.

Aspects of the indoor environment such as access to views and natural light, connection to nature, and personal control over environmental conditions all play a role in occupant comfort (see Individual Comfort Controls).[1] Access to views of the outside contributes to occupant well-being.[2] Many studies have found that people value daylight and prefer to be near windows, and there is a growing understanding that being near a window can be psychologically and physiologically beneficial, mainly if views contain natural features. Visual contact with nature through window views enhances mood, reduces stress, and promotes a higher quality of life (see Biophilic Design).[3] A study by Roger Ulrich compared postoperative recovery rates of patients experiencing similar surgical procedures but having different window views of trees and a lake, no window views, or a view of a brick wall. The study found that the window view patients recovered significantly faster, required less pharmaceutical assistance, and had fewer post-operative complications, supporting the idea that enhanced opportunities for emotionally bonding with nature promote feelings of calm, confidence, and personal well-being.[4]<br />\nOperable windows can increase occupant comfort and provide psychological benefits through natural ventilation, connection to natural elements and individual control over the indoor environment (see Natural Ventilation). Operable windows can also contribute to improved indoor air quality, depending on the quality of the outdoor air. Monitor outdoor air quality through resources such as the US EPA “Air Now” online tool (airnow.gov) that lists air quality conditions by zip code.[5]</p></div>\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_14  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_15  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				<div class=\"et_pb_text_inner\">How to Incorporate Views and Operable Windows<br />\nThe factors that define indoor environmental quality connect directly to each other. For example, the decision about the placement or type of window can impact access to natural light, connection to the outdoors, acoustics, thermal comfort, occupant control, and air quality (see Energy-Efficient Windows).[6] It is essential to consider all of these components in the design phase of a project. There are many resources available regarding design steps to consider for the placement of operable windows and to optimize views (see Resources section).<br />\nTypically homes have operable windows that provide homeowners with the option of opening and closing the windows.  With double glazed windows and screening, large windows can be used for aesthetics, daylighting and proper ventilation without unnecessary loss of heating and cooling. It is possible to have operable windows without wasting energy by integrating the HVAC system with a window switch. Whenever the system senses that the window is open, the heating and cooling air supply to that zone are turned off, allowing the open window to provide ventilation air while allowing the temperature to float. Using computer simulations, engineers have shown that natural ventilation coupled with a disabling of the HVAC system results in reduced energy use.[7]<br />\nAlthough there are many benefits associated with operable windows, there are also tradeoffs to consider. For example, operable windows can increase the threat of water and air leakage without careful window selection, design, and installation (see Reduce Air Infiltration). Operable windows can also increase noise and airborne pollutants in the interior space and make it harder to control thermal comfort with various types of HVAC systems (see Acoustic Control).<br />\nBenefits<br />\nIncorporating views and operable windows:</p>\n<p>Enhances occupant comfort and health<br />\nIncreases access to daylight and window views, which is likely to have positive impacts on psychological functioning and well-being<br />\nReduces stress and promotes positive emotional states and may also influence cognitive functioning[8]<br />\nReduces the need for mechanical ventilation<br />\nReduces energy use through increased daylighting</p>\n<p>Costs<br />\nThe cost of incorporating operable windows and maximizing views from interior spaces varies by project, and these aspects should be considered early in the design phase to optimize cost efficiencies. Operable windows are usually more expensive than static window units. Expect to pay approximately 20-percent more for fully operable windows vs. fixed windows. Price also changes by type of operable window – sliders are cheaper than casements, for example. Many factors affect cost and designers need to think holistically about the project. Operable windows can be used to offset mechanical ventilation costs and can allow for downsizing of mechanical systems. Installing a traditional mechanical HVAC unit in the home and installing operable windows can lead to inefficiencies in running the system if residents are not adequately aware of how to operate the home’s systems.[9]<br />\nResiliency<br />\nIn the event of a fire or other emergency in the home, operable windows (depending on their size) can act as a point of egress for occupants and can also serve as an access point for firefighters and their lifesaving equipment, especially if any other exits are blocked off and inaccessible to the home’s occupants. Operable windows can also help provide natural ventilation and thermal comfort during a power outage.[10]<br />\n&nbsp;<br />\n[1] Whole Building Design Guide. Promote Health and Well Being http://www.wbdg.org/design-objectives/productive/promote-health-well-being  (accessed January 12, 2019).<br />\n[2] GSA.

program of the United States Environmental Protection Agency (US EPA) and the United States Department of Energy (US DOE), labels energy-efficient products and practices using third-party certified testing to guarantee quality and performance.[1]<br />\nOn average, cooking and cleaning appliances account for 9%, computers, televisions and related equipment for 10%, and other uses or miscellaneous electronic loads (MELs) or plug loads accounting for 27% of energy use in residential buildings.[2] Plug load refers to any device plugged into the home’s electrical system including task lighting, televisions, kitchen appliances, and cell phone chargers.[3]<br />\nENERGY STAR qualified home appliances utilize advanced technologies making them 10-50% more efficient than standard appliances.[4]  Replacing conventional appliances and other electronic devices at the end of their useful life with ENERGY STAR labeled products and managing plug loads can save money through reduced energy consumption and associated cost savings.<br />\nHow to Implement ENERGY STAR Equipment and Mange Plug Loads<br />\nStep 1 – Select ENERGY STAR certified products for the home including electronics such as computers and televisions as well as home appliances, lighting fixtures, HVAC equipment,[5] and water heaters. For a complete list, see ENERGY STAR certified products.<br />\nStep 2 – Check for available incentives and rebates.<br />\nEnergy Star Rebate Finder<br />\nDatabase of State Incentives for Renewables and Efficiency (DSIRE)<br />\nNJ Clean Energy Program Residential Appliance and Lighting Incentives<br />\nStep 3  – Follow the manufacturer’s instructions or hire a professional installer as poor installation can affect the performance of equipment.<br />\nStep 4 – Manage plug loads. Eliminate or unplug unnecessary devices. Turn off or power down devices when not in use and use power management settings, timers, and advanced power plugs. Engage occupants and make sure they understand why, when, and how to power down.<br />\nExample<br />\nAcampora Residence, Barnegat, NJ.<br />\nA new home built to the NJ ENERGY STAR Homes standards, the Acampora home utilizes ENERGY STAR qualified appliances and lighting. Combined with an energy-efficient HVAC system, higher R-value insulation, and high-performance windows, the home expects annual cost savings of $480 by reducing energy consumption by 1,500 kWh and 300 therms per year compared to a conventional home or similar size.<br />\nBenefits<br />\nBy avoiding the need to generate electricity in the first place, energy-efficiency reduces emissions and air pollution related to producing energy including greenhouse gases, acidifying substances, ozone precursors, and particulate matter or precursors.[6] The installation of ENERGY STAR qualified equipment and managing plug loads in a residential building can reduce energy usage and lower energy and utility bills.[7]</p>\n<p>Extends product life and decreases maintenance<br />\nLower energy use and utility bills<br />\nIncreased resale value of an energy-efficient home</p>\n<p>Costs<br />\nAnnual energy and costs savings often justify additional upfront costs of selecting ENERGY STAR certified products over conventional products. Rebates and incentives also help reduce upfront costs.<br />\nResiliency<br />\nUse of ENERGY STAR certified products and managing plug load reduces energy usage, increasing grid reliability and reducing utility costs.<br />\n&nbsp;<br />\n[1] ENERGY STAR. http://www.energystar.gov/index.cfm?c=about.ab_index (accessed April 17, 2018).<br />\n[2] Lisa Schwartz et al. “Electricity end uses, energy-efficiency, and distributed energy resources baseline.” Energy Analysis and Environmental Impacts Division Lawrence Berkeley National Laboratory.

Reducing peak demand reduces the cost of electricity by reducing the need for additional generation capacity and avoiding the construction and maintenance costs associated with “peakers” or standby energy plants. Utility companies often charge flat rates for energy consumption. These flat rates do not factor in the different costs of supplying energy during different times or usage levels. Energy usage peaks from air conditioner use on hot days and when people come home from work between the hours of 2 pm and 7 pm. Figure 1 illustrates the results of shifting energy use away from peak hours.[2]</p></div>\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_6  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_7  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				<div class=\"et_pb_text_inner\">Increased peak demand strains the electric system, increases emissions, and adds to energy costs. In a demand response program, homeowners manage the amount and timing of energy consumption to maximize energy efficiency and reduce energy costs by shedding loads or shifting activities to off-peak hours, which often coincide with lower energy prices or incentive payments. Demand response may include interrupting demand for a short period or adjusting demand levels by shedding or shifting loads or storing energy. For example, homeowners can manually adjust or automatically set smart thermostats to cycle off during periods of peak demand and to cycle back on during off-peak hours, potentially lowering energy use and electricity bills. Advances in smart grid infrastructure including smart metering technologies have expanded the range of available demand response programs and dynamic price offerings.[3]<br />\nDemand response programs often utilize dynamic pricing models such as time-of-use pricing, real-time pricing, variable peak pricing, critical peak pricing, critical time rebates or peak time rebates.[4] Smart metering and energy management systems provide detailed consumption and cost information, often in easy to ready visual displays that allow homeowners to make informed decisions concerning overall energy usage and energy use patterns at various time intervals. Demand response enabled devices such as smart thermostats and smart water heaters can signal consumers to adjust electricity consumption manually or allow utilities or aggregators to automatically turn off air-conditioning units or water heaters to avoid peak load issues (see Smart Sensors and Controls, and Smart Meters). Demand response programs can also signal residences with on-site renewable energy generation and storage capabilities to use, store, or sell renewable energy back to the grid and encourage electric vehicle charging during off-peak, low-cost hours or charging back to the grid during periods of peak demand (see Alternative Transportation, Energy Storage and Backup Power Generation). Additionally, utilities can notify demand response participants of a potential grid failure, and incentivize participants to reduce energy use, switch to on-site generation, backup power or a combination of these load management strategies.<br />\nHow to Incorporate a Demand Response Program or Peak Load Management?<br />\nCheck with your local utility to find out about available demand response programs, eligibility requirements, and offerings in your building’s service area. Smart energy management systems and smart metering technologies provide the data and two-way communication necessary for participation in many demand response programs (see Smart Metering). Other demand response enable devices may include lighting controls, appliances, air conditioning units, and water heaters (see Smart Sensors and Controls).<br />\nPeak load management strategies may include:</p>\n<p>Activating, or turning on equipment sequentially, rather than all at once.[5]<br />\n“Coasting” the last hours of operation – turning down or off systems (such as temperature control, ventilation) while maintaining adequate levels of comfort.[6]<br />\nLoad shedding or switching loads such as running the dishwasher or washing machine during off-peak hours.[7]<br />\nLoad shifting or moving consumption to off-peak periods, such as pre-heating water heaters to a higher temperature and then allowing the temperature to fall naturally during a load reduction.<br />\nLoad-displacement or offsetting peak demand with on-site generation such as renewable sources and battery energy storage.<br />\nDemand flexibility or communication and control technologies that allow significant loads to continuously respond to changing renewable supply levels, particularly wind and solar, and other market signals.[8]</p>\n<p>Examples<br />\nAtlantic City Electric offers a demand response program for their residential customers called Energy Wise Rewards. Participants in the program have a device installed on their central air conditioning units, which allows for remote turn-off by utilities during peak periods during the summer months. Jersey Central Power and Light (JCP&amp;L) has a similar program called EasyGreen. PSE&amp;G ran a pilot program called MyPower in 2006 and 2007, but as of this writing, there is no comprehensive residential demand management program available.[9]<br />\nBenefits<br />\nDemand Response programs supported by smart grid and smart metering infrastructure provide multiple benefits to utilities, energy consumers, and the grid. By accounting for the real-time cost, availability, and source of electricity, and reducing peak consumption, demand response programs:</p>\n<p>Encourage energy conservation and reduce overall energy consumption eliminating the need for building new or maintaining older, less-efficient standby energy plants, passing savings onto ratepayers in the form of reduced electrical bills or incentive payments.[10]<br />\nReduce strain on the grid and increases grid reliability by reducing grid congestion, better balancing of supply and demand, and decreasing supply interruptions and losses.[11]<br />\nFacilitate the use and integration of cleaner energy sources[12] by adjusting demand to match intermittent wind and solar supplies.<br />\nPromote energy storage technologies, such as Vehicle-to-Grid (see Energy Storage and Backup Power Generation) that can shift load consumption to optimal times or provide backup power to the grid like a generator and support distributed renewables generation.</p>\n<p>Costs<br />\nEstablishing a demand response program and offering dynamic pricing to reduce peak demand may be cheaper and faster for a utility than building a peaker plant to meet increased demand. Demand response programs can encourage customers to modify their consumption behavior and reduce electric bills. Smart home and demand response enabling technologies, including smart energy management systems and smart metering are becoming more user-friendly, cost-competitive and widespread in the marketplace. As distributed energy resource capacity, including battery storage, grows so does the ability to shift loads and take advantage of potential cost savings and incentives offered by demand response and dynamic pricing programs.<br />\nResiliency<br />\nDemand response reduces stress on the electricity grid during times of prolonged disaster or shifts in weather. Demand response programs enable utility programs to reduce electricity demand, especially at times of system peak and increase grid reliability by avoiding system outages. Demand response programs also increase resiliency by supporting the smart grid, which aims to diversify and strengthen the electric grid through better energy management and the integration of cleaner energy sources such as wind and solar as well as electric vehicle charging and energy storage.<br />\n&nbsp;<br />\n[1] Connected Devices Alliance. “Intelligent Efficiency – A Case Study of Barriers and Solutions – Smart Homes.” March 2018. https://cda.iea-4e.org (accessed September 10, 2018).<br />\n[2] Applied Energy Journal  “Demand Side Management in a Day-Ahead Wholesale Market: A Comparison of Industrial &amp; Social Welfare Approaches” (MIT) https://amfarid.scripts.mit.edu/wpblog/tag/graph-theory/Flex  (accessed  April 19, 2018).<br />\n[3] Smart grids are electricity supply networks that use digital communications technology to detect and react to changes in energy supply and demand and manage the transport of electricity from generation sources to end users.<br />\n[4] Smart Electric Power Alliance. 2017. “2017 Utility Demand Response Market Snapshot.” https://sepapower.org/resource/2017-utility-demand-response-market-snapshot/thank-you/ (accessed September 12, 2018).<br />\n[5] BOMA International. “30 Ways to Save Energy – for little or no cost.” http://www.boma.org/research/Documents/Find%20a%20Resource/BEEPChecklist_final.pdf (accessed April 19, 2018).<br />\n[6] Ibid.<br />\n[7] Energy Exchange.

from solar, wind, geothermal, biogas, some forms of biomass, and low-impact small hydroelectric sources (i.e., do not impact land use and fisheries).[1] Homes get their power from a mix of energy sources with varying levels of environmental impacts and benefits (see Figure 1). Electricity generated from coal, nuclear, oil, natural gas, wind, and solar all goes to the same grid (see Figure 2). Renewable Energy Credits (RECs) represent 1 MWh of renewable electricity generation and provide proof of the electricity generated by green power.<br />\nEnergy-efficient single-family homes that are not ideally suited for on-site renewable energy generation can voluntarily choose to switch to green energy or purchase RECs to help offset their home’s environmental and carbon footprints.</p></div>\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_1  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_2  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				<div class=\"et_pb_text_inner\">How to Purchase Green Energy<br />\nIn New Jersey, the Electric Discount and Energy Competition Act (EDECA) of 1999 (N.J.S.A. 48:3-49) separated the supply portion of the electric rate from the delivery portion, providing the consumer the opportunity to select among third-party electricity suppliers licensed by the New Jersey Board of Public Utilities (NJBPU). Consumers can make decisions on a variety of factors including cost or energy efficiency and sources of electricity generation (e.g., nuclear, natural gas, oil, solar).[2]<br />\nThrough the purchase of green power, a home does not necessarily receive renewable energy directly, but instead, the purchase of renewable energy increases the percentage that renewable sources (e.g., solar and wind) that contribute to power production within the region. Table 1 lists various ways to purchase green energy.<br />\nTable 1 – Green Power Supply Options (Source: Adapted from US EPA).<br />\nResidential electricity consumers may choose to purchase RECs, contract with a green energy supplier or participate in a utility-sponsored green energy program. Green power products and programs often require customers to pay a premium over the standard electric price in return for green power (i.e., electricity bundled with RECs) but the utility continues to provide the electric transmission and distribution in the same way as a regular electric customer.<br />\nNote that green power supply options depend on available renewable energy resources and projects, and state and utility policies and programs. Check with your utility provider for available programs and current incentives. Other options include Power Purchase Agreements (PPAs) that directly support specific renewable energy projects.<br />\nThe decision to purchase green power involves identifying and comparing green power options among verified, third-party certified green power providers that meet nationally-accepted standards for product quality. At this time, the Center for Resource Solutions’- Green e-Certified Program is the only organization that certifies and independently verifies green power products in the United States.<br />\nBenefits<br />\nConventional electricity relies on fossil fuels and produces significant air pollution and greenhouse gas emissions. Green power provides the following environmental benefits:[3]</p>\n<p>Supports renewable energy resource and technology development either directly through PPAs and bundled green power products or indirectly through RECs.<br />\nReduces a home’s carbon footprint associated with electricity consumption.</p>\n<p>Example<br />\nJacobstown Solar Farm, Burlington County, NJ.<br />\nThe Jacobstown Solar project, by Community Energy, Inc., provides green power to the Jersey Central Power &amp; Light (JCP&amp;L) regional electric grid and helps farmland preservation in the area by providing a source of local revenue. Landscaping on the site matches the rural surroundings and plantings of low mow turf grass reduce stormwater runoff and improve soil conditions for future agricultural uses. When NJ homeowners choose to purchase green power, they support solar companies like Community Energy, Inc. and projects like the Jacobstown Solar Farm, that provide local sources of renewable energy.<br />\nCosts<br />\nWhile a switch to green power does not require any upfront capital costs, currently there exists a cost premium for green power of about 2 to 4 cents per kWh.[4] Prices for green power vary also depending on a variety of factors, including:</p>\n<p>Supply and demand variability<br />\nProduct type (e.g., RECs, PPAs, utility or competitive green power products)<br />\nPurchase volume (e.g., total kilowatt-hours)<br />\nContract length (e.g., short- or long-term)<br />\nResource and technology type (e.g., solar, wind)<br />\nGeography (e.g., local versus national)<br />\nCertification and verification status</p>\n<p>Resiliency<br />\nA switch to green power provides resiliency benefits by helping to diversify and strengthen the electric power grid through the integration of cleaner energy sources such as wind and solar and by supporting local renewable energy generators and distributed renewable energy (DER) projects.<br />\n&nbsp;<br />\n[1] US EPA.

Comprehensive green cleaning programs prioritize environmental and health issues as well as the appearance of the residence.</p></div>\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_13  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_14  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				<div class=\"et_pb_text_inner\">Some cleaning products can have human health impacts such as burns or respiratory or skin, eye, nose, throat problems on skin contact or through inhalation exposure, while others may contribute to long-term health problems such as cancer or disruption to the endocrine system. Chlorine bleach or ammonia, which are found in many toilet and drain cleaners, can be corrosive. These chemicals can cause immediate health problems upon skin and inhalation exposure as well as damage to the environment when they go down the drain.[2],[3] When harsh chemical use is necessary, use appropriate gloves to avoid or minimize skin exposure. It is also essential to have good air circulation in the room while cleaning and never mix two different types of cleaners, particularly if the products contain chlorine (bleach) and ammonia.[4]<br />\nGreen cleaning prioritizes non-toxic cleaning products and low-impact cleaning equipment and reduces the risk of exposure to hazardous chemicals.[5] Green cleaning is not just about products but also about cleaning procedures such as using the appropriate quantity of the right product for a specific job or reducing the frequency of labor-intensive tasks by using less intensive cleaning and maintenance activities more often. Simple changes such as limiting food consumption to specific areas can reduce cleaning needs and can also be part of an integrated pest management plan, reducing the need for toxic pest management chemicals (see Integrated Pest Management). Green cleaning requires a holistic approach that includes the careful selection and use of products and equipment and a reevaluation of cleaning procedures.<br />\nHow to Implement Green Cleaning<br />\nDevelop a green cleaning program that prioritizes green or natural products and green cleaning practices (see Operator and Occupant Training).<br />\nThe Healthy Children and Family Study, conducted by Rutgers University, found that the use of a mop with a microfiber cloth and the use of vinegar and baking soda as cleaners lowered airborne particulate matter concentration. Vacuuming with high-efficiency particulate air (HEPA) filters help remove particulate matter and volatile organic compounds from the air.[6]<br />\nEnvironmentally preferable purchasing (EPP) refers to products or services that have less impact on human health and the environment than competing products or services that serve the same purpose.[7] Choose environmentally preferable products that are rated green by independent, third-party organizations such as Greenguard, Green Seal, or US EPA’s Safer Choice program. It is also important to check product labels and Material Safety Data Sheets (MSDS).  Custodial equipment, such as vacuums, and green cleaning services can also earn third-party certification through programs like the Carpet and Rug Institute Seal of Approval Program and Green Seal.<br />\nBenefits<br />\n Green cleaning offers the following benefits:</p>\n<p>Protects the health and safety of residents and cleaning professionals.<br />\nReduces toxic chemicals in the indoor and outdoor environment and reduce the amount of hazardous waste requiring disposal.<br />\nImproves indoor air quality.</p>\n<p>Costs<br />\nOver the long-term, green cleaning can reduce the total cost of cleaning through reducing or eliminating hazardous cleaning chemicals. Because there are fewer toxic chemicals that employees must work with, liability exposure also is reduced. Similarly, with fewer toxic chemicals to store, track, maintain and dispose of, the cost of complying with regulatory requirements is reduced.[8] The University of Georgia’s facilities cleaning program, implemented by the Physical Plant’s building services’ department, earned recognition for a focus on cost-saving and workplace safety. The program covers 9.7 million square feet and includes a Building Services Academy that trains all department employees in green cleaning policies and procedures.[9] The University of Georgia’s program documented benefits such as a decrease in employee respiratory complaints associated with cleaning chemicals, a decrease in the number of severe employee injuries from slips/falls, and significant cost savings from transitioning from traditional cleaners to green cleaners.[10] Although not limited to residential buildings, this example helps illustrate the benefits and cost reductions of green cleaning. Many green cleaning products are cost-competitive with traditional products, and green cleaning programs offer the added benefit of protecting human health and the environment.<br />\nResiliency<br />\nGreen cleaning reduces the use of toxic and hazardous chemicals and products that can pose health hazards to the public and damage to natural resources. Reducing the need to store toxic chemicals and products helps reduce the risk, and danger of toxic substances spills or releases into the environment during an extreme event such as flooding or other disasters.[11] Minimizing the risk of toxic material spills and leaks help protect the public as well as those engaged in clean up and remediation activities, making it easier to recover after an unexpected event.<br />\n&nbsp;<br />\n[1] US EPA.

It is a decision-making process with a goal of solving pest problems with the least toxic method.  IPM programs use comprehensive information on the life cycles of pests and their interaction with the environment. This information, in combination with available pest control methods, is used to manage pest damage by the most economical means, and with the least possible hazard to people, property, and the environment.[1]<br />\nPesticides can contribute to indoor air quality problems, and other hazards include acute, immediate toxicity to humans and other non-target organisms; chronic or long-term toxicity such as cancer; and potential to contaminate air, or ground and surface water.  Some pests develop a resistance to specific pesticides, and in turn, require stronger chemicals for pest control.  Pesticide labels, Material Safety Data Sheets (MSDS) and resources such as Pesticide Action Network Pesticide Database provide information on many of these potential hazards for specific pesticides.[2] MSDS are documents prepared by a product’s manufacturer to provide information on the safe use and potential hazards of a product.<br />\nIn structural pest control (pest control in and around buildings), IPM focuses mainly on eliminating or reducing sources of food, water, and hiding spots that are available to pests, and limiting pest access into and throughout buildings. Control measures such as sanitation and building maintenance are essential aspects of a structural IPM program. Success requires the collaborative efforts of everyone involved in the management and maintenance of a building including service contractors, tenants, occupants, and cleaning staff. Education and cooperation are necessary parts of any IPM program.[3]</p></div>\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_6  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_7  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				<div class=\"et_pb_text_inner\">How to Implement Integrated Pest Management<br />\nEach IPM program is designed around individual pest prevention goals and eradication needs, considered in the context of the environment or setting. Although tailored for each setting, most successful IPM programs use the same four-tiered approach that includes 1) Setting action thresholds or defining the level for controlling a pest. 2) Monitoring and identifying pests. This step helps identify if and what pest problems exist and helps reduce the unnecessary use of pesticides. 3) Prevention, which includes proactive methods to prevent pests from becoming a threat such as repairing structural damage in a building and good garbage management. 4) Control. If necessary, implement strategic control methods such as mechanical control (trapping), or highly targeted chemicals. [4]<br />\nIPM recommendations developed Rutgers University identifies regular monitoring, repairing structural damage, proper sanitation and a combination of non-chemical/low-impact pesticides as critical components of a typical structural IPM program (see Figure 2).<br />\nHiring a vendor who uses IPM practices help ensure the safe and effective management of pests in and around the building. It is likely that vendors recommend cleaning up areas and making repairs. Simple changes may include cleaning up break rooms and not overwatering plants. More complex and expensive changes may involve patching holes and crevices, repairing leaks, sealing floor drains and vents, sealing cracks and other access areas for pests, and installing door sweeps.</div>\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_8  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_9  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				<div class=\"et_pb_text_inner\">Benefits<br />\nIntegrated Pest Management:</p>\n<p>Promotes sound structures and healthy plants<br />\nImproves pest control<br />\nPromotes sustainable bio-based pest management alternatives<br />\nReduces the environmental risk associated with pest management by encouraging the adoption of more ecologically benign control tactics<br />\nReduces or eliminates issues related to pesticide residue<br />\nDecreases occupant exposure to pesticides<br />\nReduces concern about pests &amp; pesticide-related practices<br />\nMaintains or increases the cost-effectiveness of pest management programs[5]<br />\nPrevents the contamination of indoor air, buildings, soil, and water and keeps hazardous chemicals out of the food chain<br />\nProtects people (especially children and other vulnerable populations), animals and beneficial plants and insects from toxic exposures</p>\n<p>Costs<br />\nIPM can reduce long-term pest management costs. Often IPM programs cost the same or less than traditional pest management programs. Costs may rise during the transition period as new equipment is acquired or after building upgrades. IPM can reduce costs by eliminating regular pesticide spraying, but those savings may be redirected toward preventive practices, such as training employees, inspecting for pests, and investing in building and landscaping improvements. Over time these budget shifts balance out, and improved maintenance, better sanitation and making repairs help make the building more attractive to everyone except pests.[6]<br />\nResiliency<br />\nMinimizing the use of hazardous pesticides reduces the risk of spills and contamination during an emergency event.  Less risk of pesticide exposure or dangerous chemical combinations makes clean up and recovery less dangerous and more efficient. Managing pests through an effective and environmentally sensitive program helps create a healthier indoor environment that can help protect occupant health.<br />\n[1] US EPA.

Homeowner education is the key to achieving long-term goals of cost savings, energy efficiency, resource conservation, and pollution prevention while meeting the comfort, health, and safety requirements of a home or residential building.<br />\nGreen homes and residential buildings, in particular, may contain new equipment, technologies, and maintenance activities that might be unfamiliar to residents and maintenance contractors. A formalized program of occupant training is an important step to ensure that the residents acquire the skills and knowledge they need to utilize and optimize a green home’s features and contract green contractors and service providers.</p></div>\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_1  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_2  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				<div class=\"et_pb_text_inner\">How to Implement Homeowner Training<br />\nEffective homeowner education for high-performance homes:</p>\n<p>Provides residents with training and instructions on the green features of their home and how to optimize performance<br />\nIntegrates indoor environmental quality, energy efficiency, waste management, and water conservation into standard systems and routine practices<br />\nUtilizes expert knowledge to evaluate and improve on O&amp;M practices<br />\nHighlights green and high-performance features when selecting contractors and services</p>\n<p>Homeowner education provided by building contractors may cover correctly setting and using smart sensors and controls, such as programmable thermostats, smart meters, demand control enabled appliances and other energy-saving features of the home (see Demand Response and Peak Load Management, Smart Metering, Smart Sensors, and Controls). Builders can establish clear links between maintenance activities and cost savings or resource consumption for the homeowner. Residential construction companies can provide informaton about green cleaning practices and environmentally-friendly household products, as well as information on recycling, composting, integrated pest management, and proper disposal of chemicals, paints, or other toxic materials (see Green Cleaning, Integrated Pest Management, Safe, Non-Toxic Materials, Sustainable Materials, Composting, Source Reduction and Recycling).<br />\nDepending on the climate, housing type, and landscaping, a particular focus might be given to highlight significant opportunities to meet performance expectations. For example, landscapers can emphasize water conservation measures and landscaping with native plants when households have lawns or yards (see Turf Grass Reduction). Builders and architects can help occupants identify prevailing winds that blow predominantly from one general direction throughout the year so that they might manage operable windows to take advantage of natural ventilation. In warmer or colder climates, HVAC installers can instruct residents in how to most efficiently operate air conditioning and heating systems, respectively.<br />\nHomeowner training can discuss and demonstrate maintenance needs for different equipment, including techniques and schedules of service work. Builders and equipment contractors can provide residents with copies of maintenance resources such as manuals, checklists, and charts. Finally, contractors can follow up with occupants after they have lived in a home for a period, to answer questions or address concerns about the energy efficiency features of the house, that arise after occupancy.<br />\nBenefits                                                                     <br />\nHomeowner education can help achieve sustainable performance targets of the home such as:</p>\n<p>Scheduling of preventative service and maintenance that extend the life of equipment and building materials and reduce costs (see Preventative Maintenance)<br />\nConserving energy and water by optimizing the performance of building systems (see Indoor Water Conservation and Energy Star Appliances and Plug Load)<br />\nReducing the use of toxics and minimizing solid and hazardous waste generation<br />\nProviding a high-quality indoor environment<br />\nMaintaining landscaping and grounds with minimum use of water and chemicals (see Native and Adapted Plants and Water-Efficient Landscaping)</p>\n<p>Costs<br />\nOver the long term, training for residents provides the opportunity to reduce costs through extending the life of equipment and materials, optimizing the performance of systems, and conserving resources. The prices associated with homeowner education and training vary but are usually limited to the time of consultants or experts who provide the training and the development of resources such as maintenance manuals to leave with the homeowner.<br />\nResiliency<br />\nGreen homeowner education contributes to a home’s resiliency by ensuring that a residence performs optimally during both normal operations and emergencies. Educating homeowners on how to prepare for everyday emergencies and disasters helps to avoid or mitigate potential impacts and to support recovery efforts (see Storm Preparation and Emergency Planning). Prepared individuals can react quickly and safely to situations, reduce stress on local emergency responders and resources, and support local community outreach.<br />\n&nbsp;</div>\n			</div>\n			</div><div class=\"et_pb_column et_pb_column_1_3 et_pb_column_1  et_pb_css_mix_blend_mode_passthrough et-last-child\">\n				\n				\n				\n				\n				<div class=\"et_pb_module et_pb_text et_pb_text_3  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				<div class=\"et_pb_text_inner\">Related Strategies</p>\n<p>Composting<br />\nDemand Response and Peak Load Management<br />\nGreen Cleaning<br />\nIntegrated Pest Management<br />\nPreventative Maintenance<br />\nNon-Toxic Materials<br />\nSustainable Materials<br />\nSmart Sensors and Controls<br />\nSmart Metering<br />\nSource Reduction and Recycling<br />\nStorm Preparation and Emergency Planning</div>\n			</div><div class=\"et_pb_module et_pb_text et_pb_text_4  et_pb_text_align_left et_pb_bg_layout_light\">\n				\n				\n				\n				\n				<div class=\"et_pb_text_inner\">Resources</p>\n<p>Center for Creative Land Recycling<br />\nNJ Brownfields Redevelopment Task Force<br />\nNJ DEP Office of Brownfield Reuse<br />\nNJ DEP Brownfield Remediation and Reuse<br />\nNew Jersey Known Contaminated Sites<br />\nUS EPA State Brownfields and Voluntary Response Programs, New Jersey</div>\n			</div>\n			</div>\n				\n				\n				\n				\n			</div>\n				\n				\n			</div><div class=\"et_pb_section et_pb_section_2 et_section_regular\" >\n				\n				\n				\n				\n				\n				\n				<div class=\"et_pb_row et_pb_row_1\">\n				<div class=\"et_pb_column et_pb_column_4_4 et_pb_column_2  et_pb_css_mix_blend_mode_passthrough et-last-child\">\n				\n				\n				\n				\n				<div class=\"et_pb_module et_pb_image et_pb_image_0\">\n				\n				\n				\n				\n				<span class=\"et_pb_image_wrap \"><img width=\"16\" height=\"16\" src=\"https://greenmanual.rutgers.edu/wp-content/uploads/2022/04/download-3.png\" alt=\"\" title=\"\" class=\"wp-image-2254\" /></span>\n			</div>\n			</div>\n				\n				\n				\n				\n			</div>\n				\n				\n			</div></p>\n'),(10081,2092,'_et_pb_truncate_post_date','2022-05-19 06:48:39'),(10082,2092,'_et_builder_version','VB|Divi|4.14.9'),(10083,2092,'_et_pb_show_page_creation','off'),(10084,2092,'_et_post_bg_color','#ffffff'),(10085,2092,'_et_post_bg_layout','light'),(10086,2092,'_et_pb_show_title','off'),(10087,2092,'_et_pb_post_hide_nav','default'),(10088,2092,'_et_pb_page_layout','et_full_width_page'),(10089,2092,'_et_pb_side_nav','off'),(10090,2092,'_et_pb_old_content',''),(10091,2092,'_wp_old_slug','nr-building-orientationbuilding-orientation'),(10092,2092,'_wp_old_slug','nr-natural-ventilation-2'),(10093,2092,'_wp_old_slug','nr-thermal-mass-2'),(10094,2092,'_wp_old_slug','nr-on-site-wind-energy-systems'),(10095,2092,'_wp_old_slug','nr-emergency-water-supply-and-storage'),(10096,2092,'_wp_old_slug','nr-biophilic-design-2'),(10097,2092,'_wp_old_slug','nr-wildlife-habitat-2'),(10098,2092,'_wp_old_slug','nr-high-reflectance-hardscape-materials-2'),(10099,2092,'_wp_old_slug','nr-views-and-operable-windows-2'),(10100,2092,'_wp_old_slug','nr-green-cleaning'),(10133,401,'_wp_attachment_image_alt','Figure 1 – Net-Zero Energy Residential Test Facility (NZERTF).
