Air Leakage Control and the Building Envelope System: Standards, Codes and How They are Changing
October 19 @ 1:00 PM - 2:00 PM EDT
Air barrier requirements for commercial buildings are undergoing big changes in the 2022 ASHRAE 90.1 Standard and the 2024 IECC. Continuous Air Barriers have been required in most buildings for a number of years. Recently the model commercial energy codes, ASHRAE 90.1-2022 and the 2024 IECC, have been updated to provide more specific and more stringent requirements for buildings. This presentation will provide insight from an individual who has been engaged in the code development process for years, and was specifically involved with the air leakage updates in both the ASHRAE 90.1 Standard and the IECC. The air barrier updates include clarifications to the Whole Building Performance testing methods and stringency, Design phase requirements, Material and Assembly requirements, and onsite Installation Verification requirements. I will discuss the appropriateness of applications and the interaction between the Building and Energy code requirements.
