(5.0 CEUs) Duct air leakage is one of the most challenging energy wasters that energy specialists strive to reduce. Like building air leakage, duct air leakage is difficult to measure. This course discusses two distinct ways of evaluating or measuring duct leakage: pressure-pan testing and duct-blower testing. Pressure-pan testing helps to evaluate duct leakage and locate duct leaks. Duct-blower tests quantify air leakage to help energy auditors estimate how much time and effort to spend sealing the ducts.
