As building energy professionals and weatherization experts, we all know the value of isolating uncontrolled air-leakage between the garage and the living space. However, do you have a method to evaluate this connection other than the standard zone pressure measurement? Does your air-sealing crew understand when the garage is adequately sealed without achieve 50pa WRT to the living space? This session will focus on a new testing method based on a DOE study for garage to living space connection that will provide answers to the above questions. This test method has been successfully implemented in weatherization programs in the Northeast and provides a simple process to evaluate energy and health related opportunities to addressing these critical connections.
