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

Which of the following is a purpose of pathway interruption in IAQ Control Measures?

1. To minimize energy usage

2. To control dust and debris

3. To enhance visual comfort

4. To provide thermal comfort

The correct answer is: To control dust and debris

Pathway interruption in Indoor Air Quality (IAQ) Control Measures specifically aims to control dust and debris within a construction or renovation area. This technique is employed to minimize the movement of pollutants that can affect the air quality in occupied spaces. By interrupting pathways, materials and contaminants are less likely to spread from construction zones to the broader environment. This helps maintain a healthier atmosphere for building occupants, reducing potential health risks associated with poor indoor air quality. While minimizing energy usage, enhancing visual comfort, and providing thermal comfort are important aspects of building design and construction, they are not the primary purposes of pathway interruption in the context of IAQ control. Instead, the focus is predominantly on maintaining a clean work environment and managing the introduction of dust and airborne particulates that can arise during construction activities.
