JRM, that's a very impressive house. Is it at Passive House standard?
Heated with ASHP?
My house has 6" SIP walls (5.25" EPS) & tripple pane Argon Low-E windows with 1/4" storm windows outside, so 4 layers of glass. Brick exterior.
Still way too much infiltration at front door & windows though.
I didn't crowd the pex close to the outside walls & measure about 4-5*F colder floor surface temps. there with IR gun.
"I want gold pipe. No corrosion, excellent heat transfer."
and I thought copper was getting too expensive, hehe
Diamond or graphine conduct heat best so far, but a bit too exotic.
