Passive House is an increasingly popular low-energy standard. Passive Houses must be airtight (0.60 ACH at 50 Pascals) and low energy (4.75 kBTU/ft2/year max heating and cooling demand and 38 kBTU/ft2/year maximum primary demand) — requirements that slash energy demand by about 90%. Due to increasing popularity of Passive House, media mentions like this mini-series in The Tyee — are becoming more common.
In this series, Monte Paulsen explains that the Saskatchewan Conservation House (circa 1977) was an inspiration for what eventually became Passivhaus. Unfortunately, the old house gained a garage and lost the solar thermal system. And the current owner, when asked, didn’t seem to know much about the home’s history.
After the Conservation House was built, according to Paulsen, nothing much happened with energy-efficient construction techniques until recently.
Meanwhile, general adoption of Passivhaus in Germany and Europe has led to the creation of tons of jobs. They’ve had something like a 15-year head start and the best windows come from overseas. So there’s a lot of history behind the rise of the Passivehaus/Passive House. Perhaps there’s a lot of history to be made, too.
