What is the primary purpose of an IAQP evaluation?

• A. To verify that design limits for air quality are met through objective and subjective evaluations.
• B. To maximize energy savings by reducing ventilation.
• C. To monitor only ambient weather conditions.
• D. To replace all prescriptive ventilation requirements.

Answer: (A)

The main idea behind an IAQP evaluation is to prove that the indoor air quality design criteria are satisfied using a performance-based approach, by tailoring ventilation, filtration, and source control to the building and its occupants and then verifying this with both measurements and occupant feedback. You look at actual contaminant levels and exposure estimates (objective data) and also consider occupants’ perceptions of air quality and comfort (subjective input). If this evaluation shows that the air quality limits are met under the chosen strategy, the design meets the IAQP requirements.

This is different from a purely prescriptive path, which would focus on fixed ventilation rates. IAQP isn’t primarily about energy savings, though it can influence them by allowing alternatives to fixed rates if IAQ is proven acceptable. It’s also not about monitoring only weather conditions, since indoor sources, filtration, and control measures are central to IAQP. And it doesn’t replace all prescriptive requirements; it provides an alternative pathway to demonstrate compliance with IAQ needs within the overall standard.
