Minimum IAQ Performance

EQp1 | Required


Establish minimum indoor air quality (IAQ) performance to enhance indoor air quality in the occupant space, thus contributing to the comfort and well-being of the occupants.


Meet the minimum requirements of the voluntary consensus standard ASHRAE 62-2004, Ventilation for Acceptable Indoor Air Quality Mechanical ventilation systems shall perform according to the Ventilation Rate Procedure.

Naturally ventilated buildings must comply with ASHRAE 62-2004 Section 5.1.

Modify or maintain existing building outside-air (OA) ventilation distribution system to supply at least the outdoor air ventilation rate required by ASHRAE Standard 62-2004.

If the project cannot meet the outside air requirements of ASHRAE 62.1-2004 (all other requirements must be met), it must document the space and system constraints that make it not possible, and complete an engineering assessment of the system’s maximum cubic feet per minute (CFM) capability towards meeting the requirements of ASHRAE 62.1-2004, and achieve those levels, with an absolute minimum of 10 CFM per person
