Air Leakage for Buildings (IECC 2015 R402.4)

Since 2012, blower door air leakage tests have become mandatory tests, regardless of the path chosen for compliance.

The test consists of a large fan, which is installed on an exterior door of the home. The home is depressurized/pressurized to a difference of 50 Pascals, or 0.2 IWC with respect to the outside.  The fan is then turned on to depressurize the home, and the leakage is measured.

At this pressure, the home should not leak any more than:

  • Climate Zone 4: 5 Air changes per hour (ACH) at 50PA, 5ACH50 under Illinois Energy Conservation Code, and 3 ACH50 under the national IECC code.
  • Climate Zone 5: 5 Air changes per hour (ACH) at 50PA, 5ACH50 under the Illinois Energy Conservation Code, and 3 ACH50 under the national IECC code.

This test should be performed when the house is completely finished. We like to tell our builders that when the cleaning crew is at the house, it’s the perfect time for a blower door test.

At Priority Energy, we are approved to provide blower door leakage tests nationally. Our testing crew is RESNET and/or BPI certified and is a recognized by the state of Illinois as a testing agency.

  • I just wanted to send this message to all you and say GREAT JOB!  We had a rough inspection today and passed for the Woodward Ave. house. The inspector told us "if every house I inspected looked like this one I would be out a job".

  • We were so impressed with the amount of information the Priority Energy technicians gave us during our ENERGY AUDIT.  If you are buying a house, I would strongly recommend having them do an energy audit on it, in addition to your usual home inspection.

  • There is much less dust in the house and the monthly gas and electric charges have been reduced by 10 to 15%.....I'm sure I will see greater savings over a twelve month period......thanks again.
