Starting with the 2012 IECC (International Energy Conservation Code), blower door testing is mandatory to demonstrate strict air tight construction standards. The base code requires 3 ACH50, which is a very tight building envelope. To help meet this strict code, we recommend air sealing inspections prior to drywall, and preliminary blower door testing throughout the project to assess air sealing opportunities prior to the final testing.
