for high performance buildings
The Earth Rangers Centre uses earth tubes and a double foundation wall. The energy recovery in winter and summer is sufficient to temper the air about 5º C on average and up to 10º C on cold days.

.
It has become increasingly common to provide heat recovery on ventilation systems in buildings. In fact, it is difficult to achieve the minimum energy performance requirements for a LEED or other high performance building without it. (more…)

CMHC’s EQuilibrium initiative sets new course
The 12 EQuilibrium houses will be “Net zero” energy: producing as much energy as they use over the course of a year, and could well set the course for the design and construction of future housing in Canada. [Photo: Will Bruder Architects, Ltd.]

The Canadian housing industry has seen several green design initiatives in the past number of years, ranging from R2000 to Super E. To a greater or lesser degree, each of these programs has had the effect of leveraging our newer housing stock to higher levels of performance. (more…)
