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

Which of the following is a requirement for air testing in Indoor Air Quality Assessment?

1. Must be done below 3 feet

2. Should only be done in winter

3. Must be performed 3 to 6 feet above the floor

4. Can be done without monitoring humidity

The correct answer is: Must be performed 3 to 6 feet above the floor

The requirement for air testing in Indoor Air Quality Assessment specifies that measurements must be performed at a height of 3 to 6 feet above the floor. This range is established to ensure that the air samples collected are representative of the breathing zone for occupants, which is typically considered to be between 3 and 6 feet above the ground. By sampling within this height range, the assessment accurately reflects the indoor air conditions that individuals experience while they are present in the space. Additionally, this requirement helps in capturing potential contaminants or pollutants that may be more concentrated at this height due to factors such as the thermal dynamics of the space, airflow patterns, and the location of typical indoor sources of air pollution. Measurements taken outside this specified range may not provide a clear picture of the air quality that occupants are exposed to, potentially skewing the assessment results. The other options do not align with best practices for air quality testing. For example, conducting tests exclusively in winter might overlook seasonal variations that could affect indoor air quality. Additionally, monitoring humidity levels is essential since humidity can significantly influence the presence of certain airborne pollutants and the overall comfort of the indoor environment. Therefore, performing tests at the specified height is crucial for an adequate evaluation of indoor air quality.
