Equation R403.5.2
(0.02 x square feet of conditioned space)+[15 x(number of bedrooms+1)]=Total ventilation rate(cfm)
Total ventilation—The mechanical ventilation system shall provide sufficient outdoor air to equal the total ventilation rate
average,for each one-hour period according to the above table or equation. For heat recovery ventilators(HRV)and energy
recovery ventilators(ERV)the average hourly ventilation capacity must be determined in consideration of any reduction of
exhaust or out outdoor air intake,or both,for defrost or other equipment cycling.
Continuous ventilation-A minimum of 50 percent of the total ventilation rate,but not less than 40 cfm,shall be provided,
on a continuous rate average for each one-hour period. The portion of the mechanical ventilation system intended to be
continuous may have automatic cycling controls providing the average flow rate for each hour is met.
