ASHRAE 62.2 - 2010 Ventilation Requirements
For this home to comply with ASHRAE Standard 62.2 - 2010 Ventilation and Acceptable IndoorAir Quality in
Low -Rise Residential Buildings, a minimum of60 cfm of mechanical ventilation must be provided continuously,
24 hours per day. Alternatively, an intermittently operating mechanical ventilation system may be used if the
ventilation rate is adjusted accordingly. For example, a 121 cfin mechanical ventilation system would need to
operate 12 hours per day, as long as the system operates to provide required average ventilation once each
hour.
