The Coming of Air Barriers in the National Model Building Codes

As the building design, construction, and enforcement communities become increasingly aware of the connections between air infiltration, energy efficiency, and general performance, the concept of the “continuous air barrier” is making its way into buildings.  One reflection of this is seen in proposals to require air barriers in the national model building energy codes.

As the building design, construction, and enforcement communities become increasingly aware of the connections between air infiltration, energy efficiency, and general performance, the concept of the “continuous air barrier” is making its way into buildings.  One reflection of this is seen in proposals to require air barriers in the national model building energy codes.  Some states have had air barrier requirements in their “commercial” building construction codes for several years, and those experiences have informed proposals to ASHRAE Standard 90.1, the mandatory energy code in the United States.  The impact of these new requirements on the coatings industry would be significant as designers and contractors identify cost-effective materials and approaches to achieve mandated air-tightness standards in commercial buildings.
