Whole Building Airtightness Program

Learn more about becoming an ABAA Whole Building Airtightness Technician

The Air Barrier Association of America (ABAA) is pleased to announce a new U.S.-based training and certification program: Whole Building Airtightness Program (WBAP). 

Over the past three years and countless hours of collaboration with industry professionals and the State of Washington the Whole Building Airtightness Program has come to fruition. The program is divided into two important sections. First, a 5-day intensive training program, consisting of lectures and hands-on training.  Second, is the two-part certification scheme; a comprehensive online exam and a practical field test, resulting in a certified Whole Building Airtightness Technician. 

Why the WBAP was Developed

With recent developments to enforce commercial building airtightness codes, especially in the State of Washington, the ABAA recognized the lack of trained professionals to conduct tests in a commercial setting. With this in mind the ABAA gathered a host of industry experts and developed a program to thoroughly train and certify professionals in an unbiased (non-manufacturer specific) environment to conduct airtightness building testing.
