Second modular Passive House blower door test results!

Chris Conway and crew were able to get back at the site on September 3rd for a second test, after taping of the various leaks we’d uncovered  on August 26th. The big culprits, we believe, were the gaps at each of the straps between the top and bottom modules.

The results: .40 ACH50Pa.  Our tightest house yet!

Here are a couple of before and after taping shots:
