Using blower door
tests and infrared cameras, energy audits measure air leaks and detect air infiltration or missing insulation.
A blower door
test was performed at the end of construction as part of the commissioning process to validate the actual infiltration rate, which turned out to be 0.
Tenders are invited for retro-fitting insulation and insulation upgrades to all types of residential buildings; air sealing measures to increase energy efficiency of residential buildings, using blower door
diagnostics and measurement; mechanical ventilation and minor electrical upgrades and heating system service work, repair and replacement.
If you can do a blower door
test, it will indicate how tight your building is.
While renovating the Portsmouth property Eco Sound performed periodic blower door
tests and added thermal envelope wrapping to help the home achieve Passive House standards for air-tightness.
The Blower Door
Test simulates 20 mph winds on the external walls, roof, and floor, if raised.
Standards and protocols for conducting blower door
testing to measure the envelope leakage of single-family, detached homes are well understood and consistently applied.
We would be invited into someone's house and test it using a large fan called a blower door
to find out how drafty their house was, where the leaks were, or whether it was filled with bad air from being too airtight.
A study conducted in a US home by Bayer MaterialScience LLC researchers to demonstrate the benefits of polyurethane (PU) sealants shows there was a 25 per cent reduction in airflow based on blower door
testing performed before and after the sealant was applied.
The energy auditor who did your blower door
test can come back after you've sealed up your house, measure the current level of air exchange, and make recommendations to achieve the optimal level.
Brownmiller uses specialized equipment, including an electronic blower door
that pulls the air out of the house and an infrared camera that detects where air is coming into the house, to determine what energy issues a homeowner may be having.
Quantitative methods for testing air leakage from a building, such as blower door
technology, infrared thermal imaging, and duct blasting, were also part of the training, which took place in classrooms and in hands-on laboratory exercises.
