ASHRAE 62.2 - 2010 Ventilation Requirements
For this home to comply with ASHRAE Standard 62.2 _2010 Ventilation and Acceptable Indoor Air Quality in Low -Rise Residential
Buildings, a minimum of 55 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
ctesgto proFor
example,
a
log cfm mechanical ventflation system would need to operate 12 hours per day, as Long as the system oPera
average ventilation once each hour.
