^aASHRAE 62.2 ventilation rate is calculated according to the following equation: (number of bedrooms + 1) 3 (7.5 cfm) + (square feet 3 0.01 cfm).

cfm = cubic feet per minute

ft² = square foot

Pa = Pascal

NA = not applicable

ppm = parts per million

ASHRAE = American Society of Heating, Refrigerating, and Air-Conditioning Engineers

EPA = Environmental Protection Agency
