				<div class="et_pb_text_inner">What are Entryway Systems?<br />
Entryway or “walk-off” systems are grills, grates, or mats that reduce the amount of dirt, dust, pollen, and other biological and non-biological agents entering the building.[1] Once brought indoors, these substances can enter into air circulation, and the HVAC system and the building occupants can become exposed to them. The goal is to minimize and control pollutant entry into buildings and cross-contamination of regularly occupied areas. Entryway systems can prevent 80 to 90 percent of dust, dirt, and other particles commonly tracked into a building from reaching the interior.[2] Designing exterior entrances with permanent entryway systems to catch and hold particles helps enhance indoor environmental quality by contributing to source control of dust, pollen, and other particles.[3]</p>
<p>How to Incorporate Entryway Systems<br />
Install permanent entryway systems at outside entrances to prevent dirt from entering the building. Entryway systems include permanently installed grates, grilles, or slotted systems that allow for cleaning underneath. Roll-out mats can also serve as entryway systems that protect the indoor environmental quality, but they need to be maintained weekly and be designed to guide traffic along the entire length of the mat. Incorporate specifics about entryway maintenance in the facility’s green cleaning program (see Green Cleaning).<br />
Benefits</p>
<p>Reduces contaminants/pollutants in the facility<br />
Reduces cleaning/maintenance costs<br />
Protects indoor air quality<br />
Improves indoor environmental quality<br />
Protects occupant health<br />
Protects indoor flooring surfaces<br />
Contributes to the durability of the facility</p>
<p>Costs<br />
The cost of entryway systems varies depending on the type of system installed. An entrance mat may cost as little as $4-6/sf, and a metal grate system cost approximately $20/sf (material only).[4] On average, people track over a pound of dirt a week into a building through just one entryway so reducing the amount of dirt and other particles that enter the building can reduce the cost of cleaning.[5]<br />
Resiliency<br />
Entryway systems help protect indoor air quality and the integrity of indoor flooring materials during events that cause wet conditions such as storms and flooding, contributing to the protection of occupants during and following storm events as well as the long-term durability of the facility.<br />
