Daniel Shannon made me aware of the Drake Landing Solar Community, a 52 house subdivision that is the largest subdivision of R-2000 single family homes in Canada. It intends to meet 90% of residential space heating needs by solar thermal energy with an estimated reduction of 5 tonnes of greenhouse gas (GHG) emissions per home per year.
The community uses solar panels located on garage roofs to generate thermal power and supply heat to the district heating system. During the warmer months, the heated water is distributed to a borehole thermal energy storage (BTES). As the heated water travels moved throught the pipes, heat is transferred to the surrounding earth. By the end of summer, the temperature of the earth will reach 80o C. During the winter months, the heated water from the BTES is used to heat the homes.
Very interesting - I see it's in Okotoks, Alberta: http://www.dlsc.ca/
I don't usually get excited when I see the terms "largest subdivision...in Canada" due to the cookie-cutter "plant and move on" approach. So I really hope they also consider some landscaping to reduce summertime energy use and make it look truly beautiful. But I'm guessing if they are solar, they won't be wanting to plant any trees ;-)
