Groundheat has completed a vast array of residential, commercial and institutional geothermal projects since 1985 in Canada, USA, Italy, Poland, South Korea, China, and more.
With a geo-exchange system, Victoria Commons heating and cooling is provided with no burning of natural gas or oil while the co-generation system also produces its own electricity. This can be used when the city’s electricity is more expensive, rather than generating their own power while exhaust heat is recovered and reused in the heating and cooling.
The geo-exchange system and its co-generation production provides 100% of the community’s heating and cooling and is almost emission-free with no boilers, chillers or cooling towers.
The system supplies 1,600 kilowatts of thermal power and 1,400 kilowatts of refrigerating power. This means savings of 300 tons of petroleum per year and 800 tons of carbon dioxide emissions.
The geothermal system on this location involves a 200-ton horizontal loop arrangement buried 7 feet below the store’s parking lot with 15 kilometers of piping filled with glycol, a heat transfer fluid. In the Summer, the pipes draw heat from the store and disperse it into the ground. In winter, the heat stored in the earth is pumped back into the store. Generally, this geothermal technology is sufficient to maintain a comfortable temperature within the structure.
The Burlington Walmart is expected to use an estimated 60% less energy than a typical Walmart store and reduce carbon emissions by about 141 tons.
Some notable features and principles of the sprawling 800,000-sf space include:
A hybrid approach including a geoexhange system with high-efficiency peaking boilers and fluid coolers
284 boreholes on a grid of 15-20 feet, utilizing over 80 km of underground tubing
Roof designed to encourage natural light while also help shade direct sunlight to reduce load on air conditioning
The skating rink doubles as waste heat recovery and will be used for snow melting at the entrance of the centre as well as heating the building
A roof which will reflect up to 90% of sunlight
Reductions include a 40% lowering of energy consumption and 25% decline in cost. The geothermal design will reduce roughly 2,500 tonnes of CO2 emission annually—the equivalent to removing 500 cars from the road and saving 900 hectares of rainforest per year.

Past Projects of the 80/90’s
Arthur Meighen Building Rehabilitation Project
The Arthur Meighen Building, located at 25/55 St. Clair Avenue East in mid-town Toronto, is undergoing a major rehabilitation which will reduce the building’s greenhouse gas emissions by over 80% and serve as a flagship model of the Government’s commitment to reducing its carbon footprint. The project will demonstrate the government’s commitment to the environment, incorporating elements such as a high-efficiency building envelope, a geothermal system, and photovoltaic panels.
