Preliminary blower door testing on the Conifer project was an overall success! The clients and the architect came out the jobsite today for our first air tightness testing. Our goal was 1 air change per hour at 50 pascals of pressure (ACH50). Our first test was around 0.5ACH50. After a little work by our extended team, we got things down to 0.4ACH50. It’s a promising start! If we put in more effort, we think we could probably get down to 0.3, but we are happy where we are at. We still have MEPs and another wall to could and insulate, so we will test again to ensure our air barrier integrity is in place. Thanks to for the thoughtful design and @475.supply for the air barrier consulting and products!
Shoutout to for leading the air sealing details onsite.
