Paul Staller and Susan Harris, of Hillsborough, were the first recipients in the U.S. of the much sought after "Gnat's Ass" award. Okay, so it is really not an official award, but a play on our admonition that we build houses "tighter than a gnat's ass." Paul and Sue, upon verifying that their house met the stringent Passive House air leakage standard (.6 ACH @ 50 pascals) decided to commemorate the accomplishment with a tongue in cheek plaque. It was a big surprise for us and a hilarious ending to one of the most joyful builds we have ever experienced.
