33 Rockhaven Green NW, Calgary Alberta
Your opportunity to own a unique legacy home that was one of the 13 CMHC EQuilibrium Demonstration houses built to be NetZero, with superior indoor health quality and sustainable principles.
Experience the comfort, quiet and beauty that comes with living in this one-of-a-kind home.
Tucked away in a secluded corner of the EchoHaven sustainable community in the northwest urban fringe of Calgary. Close to the ring road and the TransCanada highway, downtown Calgary is 20 minutes by car or LRT, and the airport is 25 minutes. Or get out of town quickly to the great recreation areas of Kananaskis (50 minutes) and Banff (1 hour 20 minutes).
The community of Rocky Ridge/Royal Oak is family friendly and the new Shane Homes YMCA complex is a short 5-minute walk. Royal Oak shopping centre and the Co-op is within cycling and walking distance and have just about anything you need. An excellent bike pathway network connects to natural areas, the Tuscany LRT station, and adjacent communities.
The home is warm in the winter and cool in the summer and is inexpensive to operate. No natural gas bills and no electricity costs, thanks to the 6.8 kW photovoltaic array that powers all electric loads including heating, lighting and electric car. Passive solar contributes 60% of the heating load. Summer overheating is overcome by good ventilation and chimney effect cooling.
CMHC monitored everything for 1 year to compare actual performance to pre-construction technical modeling. Monitoring was very detailed and included air quality, air changes, electric use and PV array production, solar thermal, and water use. EchoHaven house had the lowest consumption of treated potable water of all the 13 Equilibrium houses, thanks to rainwater harvesting and re-use. The real-life performance of the occupied house matched the modeling predictions. In addition, the owners have kept and recorded all electrical bills.
The house has been featured in numerous publications and media broadcasts and has been a regular venue on the EcoSolar home tours. It has received EnerGuide Certification and is the 1st NetZero home in Canada to be certified by the International Living Futures Institute. It is also the 1st ever certification for climate zone 7 (cold).
Besides zero VOC off-gassing, the materials used in construction and finishes are sustainably sourced, durable and low maintenance (not to mention beautiful and functional).

This is a wonderful, comfortable home that connects intimately with its surroundings. The big southeast living room windows look out into the environmental reserve, pond and tree stand. Regular visitors include deer, moose, coyotes, ducks and other birds and once a baby black bear came to visit. Good stargazing, no streetlights in the immediate area.
We love this home, but we are considering moving to another city in the near future.
