The city of Toronto is using the deep, chilly waters of a Great Lake as
“green” air conditioning for some of its skyscrapers. The Great Lakes Radio
Consortium’s David Sommerstein explains how:
Toronto and a provincial pension fund joined forces to form a company
called Enwave. It plunged three new intake pipes 3 miles out and 270 feet
deep into Lake Ontario. The pipes suck up near-icy water, which is used to
cool other water that’s pumped to air conditioning systems around the city.
The original water is re-used as drinking water.
Chris Asimakis is Chief Operating Officer of Enwave. He says the project
saves energy and reduces pollution.
“Literally you’re offsetting between 75 and 90 percent of the electricity that
you would have otherwise used and paid for to run a traditional type chiller.
And as a result, the air in Toronto is cleaner because we’re displacing
electricity generation from coal-fired plants, as an example.”
The project has the capacity to air condition 100 office buildings or 8,000
homes. Current clients include some of Toronto’s most prominent
landmarks, including the home of the Toronto Maple Leafs hockey team.
