Leakage Data
Per the 2018 IECC: R403.3.4 Duct leakage
(prescriptive). 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.
