A project that uses water from Lake Ontario to cool office buildings in downtown Toronto was launched yesterday. The Deep Lake Water Cooling operation was activated by Enwave District Energy. The system draws water from 83 metres below the surface of Lake Ontario and uses it to provide air conditioning to 10 buildings, including the Air Canada Centre, the Royal Bank Plaza and the TD Centre. Enwave claims the project will reduce the amount of energy required to cool the buildings by 75 per cent and remove 40,000 tonnes of carbon dioxide from the air, the equivalent of taking 8,000 cars off the road.
