The 2017 residential provisions of the DC Energy Conservation Code (ECC)* require applicable projects to conduct building leakage and duct leakage testing. The Residential ECC covers all single family homes and townhouses, as well as multifamily buildings 3 stories or less above grade. Blower door and duct leakage testing must be performed by an approved third party energy testing professional.
