The standard that outlines the method for determining air leakage rates using a blower door is ASTM E779. This standard provides the procedures for measuring the air leakage of buildings and other envelopes under controlled conditions. Specifically, it details how to use a blower door to create a pressure difference between the inside and outside of a building, which allows for accurate measurement of the amount of air leaking through the building envelope.

This standard is widely adopted and recognized in the field of building performance testing, making it essential for professionals working in areas related to energy efficiency and building airtightness. By following the guidelines set forth in ASTM E779, practitioners can ensure that their air leakage testing is consistent and reliable, which is critical for assessing a building's energy performance and overall comfort levels.
