Large Building Airtightness

As part of increasingly stringent building energy requirements, mandatory airtightness testing of large buildings has now been implemented in some North American jurisdictions and is being considered for implementation in many others. In this recorded presentation, Lorne Ricketts looks at the current state of large-building airtightness based on the results of over 500 tests and shares lessons learned regarding the successful implementation of airtightness testing as part of the construction and commissioning process.
