The builder installed a 7.43-kW solar photovoltaic electric system that should contribute about $775 to the nearly $900 in savings each year that the high-performance home will realize, compared to a home built to code (the 2009 IECC).

The 2-by-6, 24-inch on-center wood-framed walls are wrapped with a half-inch of OSB topped by two 2-inch layers of rigid foam insulation that is taped at the seams to serve as a continuous thermal blanket, a comprehensive draft barrier, and a continuous wall water barrier.

Furring strips provide a nailing surface for the siding, an air space to help siding dry, and a drainage plane providing a safe exit path for any water that gets past the siding in these dry-by-design walls.

Spray foam insulates and air-seals the rim joists while R-23 of blown-in fiberglass insulation is densely packed into the 2-by-6 wall cavities. This, combined with the R-20 of rigid foam on the exterior, provides a total wall insulation value of R-43, more than twice the insulation amount required by code.

“Honestly, quite a few times I would get a shutoff notice and go to DHS to get help to pay my electric and gas because I couldn’t afford to pay for rent and groceries and gas and everything [before owning my Zero Energy Ready Home].”
