Blower Door Test

Term from Green Building industry explained for recruiters

A Blower Door Test is a way to check how airtight a building is, which is important for energy efficiency. It's like doing a full-body checkup of a building to find where air might be leaking. Professionals use a special fan mounted in a doorway that pulls air out of the building to find these leaks. This test has become standard in green building and energy efficiency work, especially for certifications like LEED or ENERGY STAR. When someone lists this on their resume, it usually means they know how to conduct energy audits and understand building performance.
