Uses of Blower-door Testing
Blower doors can be used in a variety of types of testing. These include (but are not limited to):
- Testing residential and commercial buildings for air tightness
- Testing buildings for compliance with standards for energy efficiency, such as the IECC and ASHRAE.
- Testing building envelopes and window frames for water tightness and rain penetration
- NFPA Clean Agent Retention testing (this type of testing is usually described as a door fan test rather than a blower door test)
- Duct leakage testing of forced air heating/cooling systems - both supply (vents) ducts and return ducts can be tested to determine if and how much they leak air.
