(%): 0.0 Rate (cfm): 47 Hours/Day: 24.0 Fan Watts: 8.0 Cooling Ventilation: Natural Ventilation ASHRAE Ventilation Requirements For this home to comply with ASHRAE Standard Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings, a minimum of 44 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 88 cfm 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.
