Abstract: Building owners, designers, and contractors are becoming increasingly aware of the effect of the building enclosure on energy use. With rare exception, however, green building rating systems, energy standards like ASHRAE 90.1, and building energy codes in the U.S. all but ignore air leakage. Despite growing evidence of the benefits of air barriers, the AEC industry has been slow to adopt air leakage control as a priority. This results in buildings with admirable intentions but inadequate performance.
