What is a Air Infiltration/Blower Door Test?
The Blower Door tests are used to measure the airtightness level of building envelopes, diagnose and demonstrate air leakage problems, estimate natural infiltration rates, estimate efficiency losses from building air leakage, and certify construction integrity. The Blower Door can identify building envelope improvements that will reduce energy use and increase comfort. Blower Door airtightness measurements can also be used in HVAC equipment design and sizing decisions, and to help estimate the need for mechanical ventilation.
