This seminar will help you understand the impact of air leakage on building enclosure performance, current codes and standards for air leakage control with continuous air barriers and recent advances in implementing airtight buildings in practice. Air leakage can impact building energy performance, envelope durability and occupant's comfort. Air leakage control is generally addressed by energy codes. The US energy codes have only recently recognized the importance of air leakage. For example ASHRAE 90.1, IECC, ASHRAE 189.1, and IgCC have only recently introduced quantitative requirements for air barrier materials, assemblies or whole building airtightness. The US Army Corps of Engineers (USACE) recently introduced an air barrier program for building enclosure airtightness, which requires blower door test for whole building airtightness. This seminar will provide examples of successful implementation of USACE program.

Presented by various experts on behalf of DuPont Performance Building Solutions.
