The Air Barrier Association of America (ABAA), a national trade organization specializing in air barriers, announced the launch of the country’s, first-of-its-kind, Large Building Whole Building Airtightness Program, which includes both certification and training.

In any building, drafts or air leaks can cause serious issues for efficiency, comfort, and safety. Achieving airtightness—resistance to unintentional airflows directed both in and out of a building—is essential for any architect or construction firm that wants to maximize building performance.

As covered by EDC in the May 2011 article “Opening Windows to Cutting-Edge Education,” the Center for Energy Efficient Design (CEED) opened its doors in November 2010, as the first public school in the U.S. built according to Passive House (or Passivhaus) standards, arguably the world’s highest standards in energy-efficient construction.
