Montreal’s Biosphère is an interactive museum dedicated to environmental awareness. Due to its unique architecture, energy consumption is substantial for this 48,437-square-foot geodesic dome.
Two pumps were placed just under 300 feet deep and provide 1,757 MWh of energy per year. The installation cost $525,000 Canadian in 1998 and the payback period was under six months.
The geothermal system, combined with other efficiency strategies like solar and wind, has reduced energy usage by 459 MWh annually over a conventional electrical HVAC option.
With a facade that’s over 40% windows and a location in a cool climate zone, this 21% decrease supports the sustainable mission of the only environmental museum in North America.
