How long must permanent entryway systems be for Enhanced IAQ Strategies?

5 feet
10 feet
15 feet
20 feet

The correct answer is: 10 feet

For Enhanced Indoor Air Quality (IAQ) Strategies in the context of LEED certification, permanent entryway systems must be at least 10 feet in length. This requirement is established to mitigate the amount of dirt, debris, and moisture that can be brought into a building from pedestrian traffic. By having a longer entryway system, it allows for improved opportunities for users to clean their footwear before entering the building, thereby enhancing the overall air quality indoors. The significance of this measure is rooted in its ability to reduce the burden on HVAC systems and maintain cleaner indoor environments, which are essential for occupant health and comfort. Ensuring that the entryway is adequately sized supports the fundamental goal of promoting better indoor air quality through strategic building design and construction practices.
