ASHRAE 62.2 Basics
ASHRAE 62.2 is a minimum national standard that provides methods for achieving
acceptable Indoor Air Quality (IAQ) in typical residences. The standard has three
main components:
Whole House Ventilation – diluting the air in the main living spaces to remove unavoidable contaminants from
people, pets, cleaning, and other household pollutants. The whole house fan flow rate is determined based on the floor
space and the number of bedrooms. The whole house fan provides multiple air exchanges within the home each day.
The operation can be continuous or intermittent (cycled by a timer) if less than 1 sone.
Local Exhaust – removing high concentrations of contaminants in the rooms where they occur (kitchens and
bathrooms). The local exhaust fans can operate continuously (if less than 1 sone) at a lower flow rate (CFM), or
intermittently (cycled by a switch or timer) at a higher flow rate if 3 sones or less. If operated continuously or on a
timer the local exhaust fan flow reduces the whole house exhaust fan flow requirement.
Source Control – preventing or limiting the introduction of pollutants.
