The Passivhaus Had North American Ancestry

Saskatchewan Conservation House, 1977, in the Tyee

Monte Paulsen of the Tyee describes a house built in 1977 by the Saskatchewan Research Council:

It was built without a furnace. Instead, the northwest Regina home features a nearly airtight envelope with R-40 wall insulation and R-60 roof insulation. This enables a small hot water system to heat the house, even through the winter. The house is cube-shaped to expose a minimum amount of exterior surface area per square foot of floor space.

That sounds pretty much like our beloved Passivhaus, and for good reason.
Paulsen writes:

The world would have forgotten the Saskatchewan house, too, were it not for a quirky German physicist interested in energy-saving buildings. After studying the Saskatchewan house and a handful of similar buildings, Dr. Wolfgang Feist wrote a mathematically precise -- and elegantly simple -- criterion for designing buildings that require less than a tenth of the energy of average buildings. He called it the Passivhaus standard.

Paulsen writes a terrific three part series on the Passivhaus, graciously quoting:

"Forget Energy Star and LEED," the influential blog TreeHugger declared last year, "Green building is Passivhaus."
