IAQ stands for?

IAQ stands for?

• A. Internal Air Quantity
• B. Indoor Air Quality Management
• C. Infiltration and Air Quality
• D. Indoor Air Quality

Answer: (D)

Indoor Air Quality describes the condition of the air inside buildings as it affects occupants’ health, comfort, and performance. When you see IAQ, think about how clean and healthy the indoor air is, including factors like pollutants, humidity, ventilation effectiveness, filtration, CO2 levels, VOCs, particulates, and odors. This makes Indoor Air Quality the correct term, as it is the standard, widely used phrase in codes, standards, and commissioning practice. The other options aren’t standard terms for what IAQ stands for—Internal Air Quantity isn’t a recognized term, Indoor Air Quality Management refers to the program or process rather than the abbreviation itself, and Infiltration and Air Quality mixes concepts rather than naming the concept IAQ.
