Air barriers significantly reduce energy use in buildings by minimizing air leakage, debunking long-held myths about “breathable” buildings and demonstrating through research and field testing that airtight construction—when paired with proper ventilation—improves energy efficiency, durability, and indoor air quality.
Buildings need to breathe and we need to be careful how tight we make a building. The building will not really use that much more energy if it's not too tight. These are the myths that are circulating when people discuss the installation of air barriers that needs to be addressed. The work done by the U.S. Department of Energy, Oakridge National Laboratories, Syracuse University and the Air Barrier Association of America have answered the questions about whether a tight building can really save energy. The Army Corps of Engineers has shown how tightly we can build or renovate buildings. This information has then been translated into practical ways of benefiting from the proper installation of air barriers.
