How-To
Video Vault: Home-Energy Audits Save Homeowners Money
Blower-door tests improve efficiency and lower energy costs by finding where heated air escapes.
In this gem from the Fine Homebuilding Video Vault, John Jennings, technical director at Steven Winter Associates, helps homeowner Dan Morrison answer the question: How does my house perform? John’s team starts with a blower-door test to identify and gauge air leaks; then they head to the attic armed with caulk and foam to seal those penetrations. Finally, because it is important for John’s team to “test their way in and test their way out,” they run a second blower-door test, measure the difference, and evaluate their work.
To get the answers to the other questions Dan asked, check out our Ask the Energy Expert Video Series.
