Whole Building Air Leakage Testing FAQs

Am I required to have Whole Building Air Leakage Testing?

While the US military has specific requirements pertaining to testing, not all States have requirements. This often falls on the building owner’s request or desire to have reassurance that their facility was properly constructed.

How is Air Barrier Square determined?

This is a combination of the roof, wall and exterior wall square footage (a six sided box).

Is there a way to assess an air barrier approach prior to construction?
