Can CCW-705 or Barriseal Membrane Air Barriers Save Energy?
Yes. Carlisle’s membrane air barriers, CCW-705 self-adhering and Barriseal fluid-applied, provide air tight wall construction meeting or exceeding the reduced air leakage target indicated in a recently-released report by the National Institute of Standards (NIST) entitled “Investigation of the Impact of Commercial Building Envelope Airtightness on HVAC Energy Use”. To view this report, go to http://fire.nist.gov/nist.pdf For some time, the U.S. Department of Energy has attributed some 40% of annual HVAC energy use in typical construction to air leakage. The aforementioned report by the (NIST) confirms this hypothesis. In this NIST report, different types of commercial buildings throughout the United States were studied. A considerable amount of air leakage and energy consumption data was compiled. Using conventional ASHRAE calculations for energy consumption in HVAC operations, differences in energy usage were determined as a result of reduction in building air leakage. The reduced air
