This seminar will review the impact of air leakage on building enclosure performance, current codes and standards for air leakage control and recent advances in implementing airtight buildings in practice. Air leakage is important because it can transport heat, moisture and contaminants through the building enclosure and can impact building energy performance, envelope durability and occupants’ comfort. A continuous air barrier is critical for air leakage control. ASHRAE 90.1-2010 was the first code to introduce continuous air barriers as a mandatory requirement. Air barrier performance requirements which include air infiltration resistance, continuity, structural integrity and durability will be reviewed. Energy codes which regulate air barrier requirements will be highlighted along with the three compliance options: air barrier materials, assemblies and whole building airtightness. The US Army Corps of Engineers (USACE) introduced the first air barrier program which requires blower door test for whole building airtightness.
The seminar is organized in 3 sections: − Section 1 will discuss the impact of air leakage on building enclosure performance − Section 2 will review the main air barrier requirements and air barrier codes − Section 3 will highlight the USACE air barrier program and a few examples of successful implementation of whole building airtightness testing
