ASHRAE 62.2-2010 Ventilation Requirements
For this home to wmply withASHRAE Standard 622-2010 Ventila6on and Acceptable IndoorAir Qualily in
Low-Rise Residential Buildings,a minimum of 62 cfm of inechanical ventifation must be provided continuously,
24 hours per day. ARernataey,an intermittently operating mechanical ventilation system may be used'rfthe
ventilation rate is adjusted accordingly. For example,a 123 cfrn mechanical ventilation system wouki need to
operate 12 hours per day,as long as the system operates to provide required average ventilation once each
hour.
