    • THE HISTORY OF SUPERINSULATED HOUSES IN NORTH AMERICA Martin Holladay Senior editor, GreenBuildingAdvisor.com British Columbia Building Envelope Council Vancouver, British Columbia September 22, 2010 ©MARTIN HOLLADAY, GREENBUILDINGADVISOR.COM
    • 1973: THE OPEC OIL EMBARGO The OPEC oil embargo caused the price of oil to rise from $3.56 a barrel in October 1973 to $11.65 in January 1974. President Nixon declared that the U.S. will achieve energy independence by 1980. ©MARTIN HOLLADAY, GREENBUILDINGADVISOR.COM
    • 1976: THE LO-CAL HOUSE In 1976, Wayne Schick at the University of Illinois at Urbana-Champaign developed a design for a superinsulated house that he - ©MARTIN HOLLADAY, GREENBUILDINGADVISOR.COM
    • 1976: THE LO-CAL HOUSE Long axis of the house is oriented east-west. Double 2x4 walls (R-30) R-33 ceiling Triple-glazed windows An air-to-air heat exchanger ©MARTIN HOLLADAY, GREENBUILDINGADVISOR.COM
    • 1977: SASKATCHEWAN CONSERVATION HOUSE R-40 walls R-60 ceiling Triple-glazed windows Heat-recovery ventilation Drainwater heat exchanger 0.8 ac/h @ 50 pascals ©MARTIN HOLLADAY, GREENBUILDINGADVISOR.COM
    • 1979: THE WHITE HOUSE GETS SOLAR THERMAL On June 20, 1979, Jimmy Carter inaugurated the newly installed solar hot water system on the White House roof. ©MARTIN HOLLADAY, GREENBUILDINGADVISOR.COM
    • EVERYTHING IS IN PLACE So, in 1985, everything is in place: The research has been done; There are books and magazines that provide superinsulation details; Builders can buy low-e windows, HRVs, and blower doors. So what happened? ©MARTIN HOLLADAY, GREENBUILDINGADVISOR.COM
    • DROPPING THE BALL The price of oil dropped from $32 per barrel in 1982 to $11 in 1986. In the U.S., President Reagan slashed funding for a variety of energyefficiency programs established by Jimmy Carter. ©MARTIN HOLLADAY, GREENBUILDINGADVISOR.COM
    • IGNORED AND FORGOTTEN They were hippies and Canadians. ©MARTIN HOLLADAY, GREENBUILDINGADVISOR.COM
    • 1996: FEIST FOUNDS PASSIVHAUS INSTITUT Dr. Wolfgang Feist: the first Passivhaus prototype started in 1990. At the time we knew about other similar buildings buildings made by William Schurcliff and Harold Orr and we relied on these ©MARTIN HOLLADAY, GREENBUILDINGADVISOR.COM
