Calculate required outdoor air ventilation for residential (62.2) and light commercial (62.1) spaces per ASHRAE standards.
ASHRAE 62.2 sets minimum ventilation rates for residential buildings. The formula is 0.03 CFM per sq ft + 7.5 CFM per person (bedrooms + 1). For a 2,000 sq ft, 3-bedroom home: 0.03 × 2000 + 7.5 × 4 = 90 CFM of continuous outdoor air.
