Abstract

Duct leakage often needs to be measured to demonstrate compliance with codes and standards requirements or to determine energy or indoor air quality impacts. There are several test methods available and documented in standards. Repeatability errors need to be understood because standards and codes need consistent evaluation procedures and because repeatability is also an indication of the resolution of the test method. This study focused on those test methods that are commonly used and are required by various organizations such as BPI, ACCA, RESNET, DOE Weatherization, and many other energy efficiency programs and in various test standards such as ASHRAE Standard 62.2 and ASHRAE Standard 152, and California Title 24. The three duct leak measurement methods assessed were two duct pressurization methods that are commonly used by many practitioners and the DeltaQ technique. This study assessed each measurement technique using data from the literature and recently obtained field data. The field data were taken in 30 homes in three locations in the U.S. Each home was tested multiple times with each measurement technique. The results of this study can be used by organizations such as BPI, ACCA, RESNET, ASHRAE, and other building codes and standards in determining what tests are appropriate for their specific application.
