A call to Builders and Architects: Does the Homeowner Know You’re a Blowerdoor Virgin?

When setting out to build an efficient house, the elephant in the room is air tightness. Industry is resisting mandated air tightness testing if thresholds are introduced meanwhile building codes are ratcheting up efficiency on all fronts except air tightness. Having debunked the myth that “a house needs to breath” its becoming painfully obvious to any building scientist that the lowest hanging fruit on the efficiency tree isn’t geothermal but simply producing a more air tight home. You'll have…See More

"Ed, You put your finger on it: air seal floor cavity! The volume is triangular and the weight and force with dense pack will be borne by the soffit. I love cellulose, but may be best to open it up from below (or if re-roofing pull back the…"

"Mr. Poll, I'd take your list for our climate and edit it down to: 4.  As always with ice dams, air sealing and insulation are the first concerns.  Once that is done, then venting can be addressed. 6. Air tightness test and IR can…"

Tucking a garage under the second floor is a common practice, but is it a GOOD one?

As the price of land edges up, the practice of tucking a garage under the second floor of a house is common practice, but is it good practice? The bedroom above the garage has earned the moniker of “The Bonus Room” as it tends to be the most troublesome room in the house with the most comfort complaints from home owners. Its common to tuck the double car garage into the face of the house…See More

Spot the Design Weakness - For Northern Climates

If we had a dime for each weak building assembly detail we saw, we’d be rich. In our 14 years of diagnosing comfort problems for clients; the exposed floor ranks as one of the most stark discomfort features of a home, new or old.

LOL.  Greg, sometimes you just have to take some chances...  The house is literally 1.3 blocks away from my house, so the risk was pretty small.  

This summer I pulled the disconnect on one of the AC units.  That risk is bigger as the thing is on the garage roof...
