This blog, a report on my three-day visit to Passivhaus construction sites and the Passive House Northwest conference in Washington state, picks up where last week’s blog left off.
After leaving the North residence job site, we drove to the Freas house, another construction site in Olympia. The steep site has a dramatic view of Budd Inlet, an arm of Puget Sound, to the west.

The agency in charge of building the plants, the Washington Public Power Supply System, had an unfortunate acronym: WPPSS. Almost immediately, the acronym began being pronounced “Whoops.”
Whoops indeed. A variety of factors —…
