Webinar – Commercial Envelope Air Leakage Testing: IECC & ASHRAE 2019 vs 2022 90.1 Alignment

Join us as our special guest, Doug Hansley-Pauly from DHP Energy LLC in Oregon, explores the evolving requirements for commercial building envelope air leakage testing—commonly referred to as blower door testing—under the International Energy Conservation Code (IECC) and ASHRAE 90.1. We’ll break down when whole-building air leakage testing is required, when visual inspection is allowed, and how these provisions align (or differ) from ASHRAE 90.1 compliance paths.

Attendees will gain practical insight into enforcement, testing procedures, documentation requirements, and common pitfalls seen in the field—helping jurisdictions, designers, and inspectors ensure compliance and improve building performance.

Topics / Lessons Learned:

• When air barrier testing is required vs. when visual inspection is permitted
• Key differences between 2019 and 2022 ASHRAE envelope leakage requirements
• How IECC and ASHRAE 90.1 compliance paths impact air leakage testing decisions
• Common field issues, documentation gaps, and enforcement strategies for jurisdictions
