Sustainability In The Extreme
In the village of Mayo, Yukon, Canada, the daily mean temperature in January is
-25.7C. Yet even here, just 300 kilometers from the Arctic Circle, DEC’s concept of low-temperature district energy sharing is viable. The First Nation of Na-cho Nyak Dun, in partnership with the Governments of Canada and Yukon has chosen a geo-thermal DESS to heat, cool and provide domestic hot water for their new Government House, designed by Canadian architect Rob Sieniuc. The system, employing geo-exchange, earth tubes and solar technologies, has the capacity to expand to other buildings in the community.
Perhaps surprisingly, the fundamental advantages of a DESS – low capital and operating costs, energy conservation, low environmental impact – hold true here in the harsh and extreme climate of central Yukon, just as they do in more temperate regions.
