LEED AP Building Design and Construction (BD+C) Practice Exam

In terms of indoor air quality, what is the purpose of a permanent entryway system?

1. Reduce energy consumption

2. Improve aesthetics

3. Enhance indoor air quality

4. Facilitate access

The correct answer is: Enhance indoor air quality

A permanent entryway system is designed primarily to enhance indoor air quality by reducing the amount of dirt, debris, and pollutants that can enter a building from the outside. These systems often consist of mats, grates, or other features that trap contaminants from shoes and other sources before they can spread throughout the interior space. By effectively capturing and minimizing the infiltration of outdoor pollutants, such as dust, allergens, and moisture, these systems play a critical role in maintaining a healthier indoor environment. This is particularly important as poor indoor air quality can lead to various health issues, decreased productivity, and overall discomfort for occupants. While reducing energy consumption can be a secondary benefit by helping maintain consistent interior temperatures and reducing the load on HVAC systems, the primary focus of a permanent entryway system in the context of indoor air quality is directly related to improving the health and comfort of the building's occupants. Therefore, enhancing indoor air quality is the most relevant purpose for a permanent entryway system within the scope of LEED BD+C standards.
