The project was completed in August 2007 and the Grand Opening was in September 2007. Their first 5-year-plan's goal of achieving 90% of its space heating from the Sun was surpassed, with solar energy providing each home with 97% of its space heating needs.<Ref name=nrcan/> In addition to space heating, 60% of each home's [[domestic water heating]] needs are also met by solar energy, with the rest being supplied by [[natural gas]].

==How it works==

===Heat Capture and Storage===

800 solar collectors are located on garage roofs throughout the community, and the array collects a total of 1.5 [[megawatts thermal|MW]] of thermal energy during a typical summer day. These collectors [[heat]] a glycol solution (antifreeze) which circulates underground towards the community's Energy Centre.<ref name=dlsc/> Working as a [[heat exchanger]], the pipes containing the glycol [[heat transfer|transfer heat]] to a short-term storage water tank. This water is distributed to an underground borehole system, in which pipes are buried 37 [[meter]]s underground and hot water is made to circulate through them in order to heat the ground, effectively storing the heat for later use.<ref name=dlsc/>

The ground reaches a [[temperature]] of about 80°C before winter months, and to avoid heat loss it is covered with high [[density]] [[r-value|R-40]] [[insulation]], sand, clay, and other materials.

===Heat distribution===

Come winter, when the homes need extensive space heating, the borehole system can be made to heat the water from the Energy Centre's water tank. This heat is then circulated to each home through the district heating loop, where it passes through each home's own heating system. In the heating system this water heats air which can be blown through the ductwork and into the home. When the sufficient temperature is met in the home, a [[thermostat]] automatically regulates the heating and keeps the home at a comfortable temperature.
