Fog testing is a practical and revealing method for verifying air barrier performance in building construction. Traditional fog testing demands three key components for meaningful results: a fog generator, an enclosure to contain and create a pressure differential across the assembly, and a variable speed fan to pressurize the enclosure. We have streamlined this process […]

This presentation examines how building enclosure performance requirements have evolved from LEED v4 to LEED v5 through updates to ASHRAE 90.1-2010, -2019, and -2022, and explores the implications of these changes for enclosure design, moisture management, indoor air quality, thermal comfort, and overall building performance. As enclosure assemblies have become tighter to meet increasingly stringent […]

Owners don’t reward good intentions—they reward verified performance. This session shows air barrier practitioners, architects, contractors, and Cx providers how to move from drawings to passing results with a clear, repeatable path that works at entry, intermediate, and advanced levels. We start with why now (IECC/ASHRAE drivers and owner risk) and a plain-English methods decoder […]
