Article Highlights Ways to Boost Energy Efficiency of Attics
July 26, 2011
DOE's Building America research teams have identified air sealing as one of the most cost-effective ways to reduce building energy loads. In fact, in a recent article in Qualified Remodeler magazine, Steve Easley of the Building America Retrofit Alliance (BARA) research team asserts that a combination of air sealing and insulation in the attic can reduce air leakage by up to 40% and cut the home’s space-conditioning costs by 20%-40%.
Published in the June 2011 issue, Attic: Easy Energy Efficiency, outlines three main culprits of heat loss in attics: rising warm air from conditioned spaces in the home; outside air entering from gaps in the building envelope; and improperly sealed bypasses. Detailed instructions on effective ways to air seal an attic and reduce the uncontrolled transfer of heat to and from the conditioned living space are provided, as well as safety tips for working in attics.
