June 24, 2011- Our first blower door test for air tightness came in at ACH50 of 0.51 air changes per hour at a pressure difference of 50 pascals applied across the building envelope.  ACH50 of 0.6 or less meets Passive House standards.  With the help of the "sucker door" to help find air leaks, this number should come down considerably.  More detailed description and TrekHaus photos of today's "sucker door" and blower door tests are on the Earth Advantage Facebook page here.
