Passive House moves on to renovation focus
September 23, 2021
Passive House, the aggressive energy-saving construction program, has never achieved the traction in Canada that proponents expected, despite decades of demonstration projects.
As of 2018, only about 2,000 such houses had been built in Canada, according to Passive House Canada, and the dial has not moved much since then even with evidence that the concept can reduce home heating costs to near zero.
Drawbacks to Passive House acceptance include the much thicker walls needed for the extreme insulation, smaller windows, costly ventilation systems in the air-tight homes, and site orientation that can be at odds with esthetics and consumer demand.
Now Passive House is pushing energy-saving home renovations as EnerPHit projects.
“The EnerPHit standard is a Passive House standard intended for refurbishment projects. It allows for more wiggle room compared to the traditional standard to accommodate retrofitting challenges, while still achieving the superior comfort and performance Passive House buildings are known for,” Passive House Canada explained.
The organization announced a two-day virtual event in September 2021, the Tower Retrofit Symposium, to promote and explain Passive House renovations.
With recent federal government funding support for energy-saving renovation programs, the idea may gain traction.
“The symposium will feature engaging sessions that span the spectrum of knowledge on deep energy retrofits and EnerPHit projects. There are over 30 speakers from a number of leading organizations including The Atmospheric Fund, Toronto Community Housing, Natural Resources Canada and Vancity Community,” according to a release.
The Tower Retrofit Symposium will be held September 22 to 23, 2021 from 10:00 a.m. to 6:30 p.m. Eastern Standard Time each day.
