Lake Cooled Air Conditioning

Toronto is undergoing an air conditioning revolution that saves money and cuts down on CO2 production. Water from the depths of Lake Ontario is pumped into the basements of participating buildings and piped around them to cool the interiors. the warmed water is then sent back down to the basement where a heat exchanger cools it again whilst warming the city’s water supply. All in all a low impact, low energy solution. London is looking into a similar system utilising the water pumped out of the Underground.
