The total leakage of the ducts, where measured in accordance with Section R403.3.3, shall be as follows: 1.) Postconstruction test: Total leakage shall be less than or equal to 4 CFM per 100 SF of conditioned floor area. Maximum allowable: 4 CFM x 2,949/100 sq ft = 118 CFM at 25 Pa * Total Duct Leakage - DOES NOT PASS * Duct Leakage to Outdoors - If considered, this project would pass at 113.7 cfm.
