The City of Toronto have created an innovative cooling system that brings an alternative to conventional air conditioning to cool Toronto’s downtown core — one that is clean, price competitive and energy efficient. A permanent layer of icy-cold (4°C) water 83 meters below the surface of Lake Ontario provides naturally cold water.

This water is the renewable source of energy that Enwave’s leading-edge technology uses to cool office towers, sports & entertainment complexes and proposed waterfront developments.

Enwave’s three intake pipes draw water from 83 meters below the surface of Lake Ontario. Naturally cold water makes its way to the City’s John Street Pumping Station. There, heat exchangers facilitate the energy transfer between the icy cold lake water and the Enwave closed chilled water supply loop. This cold energy cools Toronto’s leading office buildings.
