Building Progress 2: June to July 2011

June 3 & 8, 2011- 2nd floor framing and roof going up


June 17, 2011- Triple-glazed Thermotech Fiberglass windows going in.
South windows: U- 0.14, SHGC- 0.61
North/East/West windows: U- 0.13, SHGC- 0.29

Tape is used for the air barrier.

Good looking windows!  Now look who's smiling?

June 24, 2011- Doors in!

Rob and Bart's "sucker door test" helps locate air leakage.

1st TrekHaus blower door test meets Passive House air tightness standards (ACH50 < 0.6)!
Our test came in at ACH50 of 0.51 air changes per hour at 50 pascals pressure difference applied across building envelope.  This number should come down considerably as we fill in air leaks!  For more details and photos about today's sucker door test and blower door test, see photos from Earth Advantage's Facebook page here.
