2021 IECC: Commercial Blower Door Testing

The 2021 IECC made significant changes to the commercial building envelope air sealing requirements. The most notable changes are the mandatory pressure testing of commercial buildings in most climate zones (including both Illinois climate zones) and envelope commissioning for envelope areas that are not pressure tested. In this webinar, we’ll cover how these changes impact energy code compliance in Illinois, when to do testing, how the test is set up and performed, and how to interpret the test results for energy code compliance.
