Technology Brief: Air Sealing In Multifamily Buildings
June 4, 2019
Improving air sealing is an important strategy to reduce energy waste in buildings. Across much of the U.S., air leakage testing in single-family homes has become an established practice for residential new construction ever since the 2009 International Energy Conservation Code (IECC) was published. Yet the more complex practice of air sealing in multifamily buildings hasn’t yet become a common practice due to limited code enforcement by building departments and concerns about whether tighter air sealing is achievable in these buildings. This new SWEEP Technology Brief dives deeper into the doability of the practice by looking at a case study from Utah.
