What is the goal of the Indoor Air Quality Procedure (IAQP) in ASHRAE 62.1?

• A. To minimize energy use
• B. To ensure acceptable indoor air quality by controlling contaminants and providing adequate ventilation.
• C. To maximize outdoor air delivery for all spaces
• D. To meet thermal comfort only

Answer: (B)

The Intent of the IAQP is to ensure acceptable indoor air quality by controlling contaminants at the source and providing adequate ventilation to dilute and remove those contaminants. This performance-based approach sits alongside the prescriptive ventilation requirements, offering a way to meet IAQ targets by focusing on where pollutants come from and how air is brought in and filtered, rather than simply chasing higher outdoor-air flow or just aiming for energy savings. Energy considerations can influence design, but the primary goal is IAQ—keeping contaminant levels within acceptable limits for occupants. The other options miss this IAQ-focused objective: energy minimization, universally maximizing outdoor air, or only achieving thermal comfort do not capture the purpose of IAQP.
