适用范围：The current methodology for intermittent ventilation ignored the impact of infiltration on the equivalent annual dose calculation which is the basis of this requirement. This new methodology assumes an infiltration rate of 0.02 cfm/sq. ft. of floor area and an occupancy area of 400 sq. ft./person. Higher occupancy areas and/or higher infiltration rates would result in lower equivalent annual doses than the proposed new methodology. In general, this new methodology results in lower allowable intermittent ventilation rates.
