That's a gorgeous attic! To my eye, the bungalow is a beautify style that can accommodate high performance discretely. The only aspect of this building that looks less solid (visually) and a little inconsistent is the roof…"
I am also very interested in what you find from aggregating DER performance across the U.S. Performance data is going to be key to the general public's evaluation of this level of retrofit. It is exciting to see such…"
Linda Wigington distinguished between deep retrofits & deep energy reductions, thus expanding the range of strategies & tactics from which we might propose when engaging with people, the ones who choose.See More
There are a few important considerations that I think people often miss when deciding between or comparing establishing the thermal enclosure at the attic floor or in the plane of the roof. First, to really do the same…"
"Kevin, I agree, he would be wasting his money to seal the sub-slab ductwork.
There is only one appropriate retrofit measure for ducts below a slab: fill with concrete and relocate ductwork within the building.
I've put a camera in a sub-slab…"
"Thank you for this post, Chris!
Of course we all want the efficiency of mini-splits in a ducted system. The trouble seems to be, however, that once we put ducts on these systems, they no longer have a performance advantage over…"
If you've insulated the pipe, sloped to the outside, properly lapped the joints, left a drain hole or two at the bottom of the vent termination...then I think you're just up against physics. Physics wins every time.
"Appreciate the thoughts, Glen. But I think you need to be careful about the terminology. Building science is science. It's the application of building science that tends to be less scientific. The discipline of building…"
