What does testing for IAQ in ASHRAE 62.1 involve?

• A. Methods to test concentrations of contaminants and verify ventilation performance.
• B. Calibrating thermostats to maintain setpoint.
• C. Measuring only energy use to infer air quality.
• D. Recording occupant satisfaction surveys.

Answer: (A)

Testing IAQ per ASHRAE 62.1 centers on measuring actual contaminant concentrations and confirming that the ventilation system is delivering the intended outdoor air and removing pollutants as designed. This means checking things like CO2, VOCs, particulates, or other relevant contaminants to ensure they stay within acceptable limits, and independently verifying that the ventilation rates, outdoor air delivery, filtration, and overall airflow performance meet the standard’s requirements.

Calibrating thermostats to maintain a setpoint addresses temperature control, not IAQ testing. Measuring only energy use to infer air quality can be misleading because energy data don’t directly quantify pollutant levels or ventilation effectiveness. Recording occupant satisfaction surveys is subjective and does not provide the objective measurements of contaminant concentrations or ventilation performance required to verify IAQ.
