Blower door did not suck

There are too many bad jokes to be made about blower doors...I couldn't resist.

This is just a very quick post to announce the our PHIUS+ rater, Andy Scott of Energistics, came to the site this week and performed the preliminary blower door test.  As soon as we turned the fan on we started smelling sewer gas (plumbing is just at rough, so no traps installed.  So we plugged them with rags and fiberglass (not exactly airtight, but kept the stink down and gave us a more accurate reading.  Andy didn't have a "C ring" to be able to get below 300cfm, so Brandon got one from his truck... he is wearing it like a hat...
...and we got the reading: 240cfm, which translates to about 0.38ACH50, well below the 0.6 Passive House threshold, and we will be able to tighten a bit more with the plumbing.  A big congratulations are in order for Brandon and Eric for sealing the windows and doors so well...
tiny crack at the miter--but needs to be there to allow glass to be replaced

great seals on the doors and windows well as the few penetrations through the ceiling.
gaskets were perfect
I'll say it again: this is a great team!
