Duct leakage is a subtle yet significant cause of energy inefficiency in residential heating and cooling systems. ASHRAE's role to identify, measure, and quantify these energy losses in a definitive sense will enable others to implement real-world solutions to this element of the energy problem. ASHRAE research on duct leakage testing is very much needed to ensure adequate coverage of this vital question.

The objective of this research project is to develop faster, better, cheaper residential duct leakage test procedures. The criteria for judging the merit of a test are indicated by the three adjectives: faster=minimize labor hours; better=maximize reproducibility and accuracy; cheaper=require least capital outlay for test equipment.
