Covering 217 hectares, the Blatchford development is an innovative and environmentally-friendly community with a world-leading, district energy system. This district energy system running on renewable energy is an integral component of the Blatchford redevelopment, providing heating, cooling, and domestic hot water for the entire community. The geoexchange field is installed beneath a stormwater retention pond, and includes one of the first uses of graphite-enhanced grout in boreholes – the largest geoexchange field employing this application in Canada.
It is the largest application of an ambient- temperature distribution system in Canada, that allows for efficient use of heat pumps, integration of other low-temperature sources, such as sewer heat exchange, and energy sharing between buildings.
Combining the benefits of building energy efficiency, energy sharing within the system, and highly efficient heat pumps results in greenhouse gas reductions at 75% below business-as-usual levels.
