Large Building Blower Door Testing – Session Part 1

A three-part progressive technical learning series covering the complete large building blower door testing process. Beginning with an understanding of the applicable standards, testing protocols, performance targets and metrics, the series progresses through building and test preparation and concludes with the actual testing process, interpretation of results and practical solutions.

Each session builds on the knowledge developed in the previous session, taking participants from understanding what needs to be achieved, through how to properly prepare for testing, to conducting the test and understanding what the results mean. The series is designed for architects, engineers, builders, developers, property managers and other professionals involved in the design, construction and performance of large buildings.

Part 1 establishes the technical foundation for large building blower door testing. The session explores applicable testing standards and protocols, including ASTM, CGSB, U.S. Army Corps of Engineers, and other recognized methodologies.

Participants will gain an understanding of the different performance targets and metrics, how they are calculated and compared, and what they mean for a project. The session will examine what is being tested, why airtightness testing is required, how performance is measured, and what constitutes a successful result—providing the foundation needed to properly plan for building preparation and testing.
