Everything you need
Toronto has everything you need for deep lake cooling. A downtown with high-rise density, a high-level of year-round demand for cooling and air conditioning adjacent to a supply of consistently cold water. The waters of Lake Ontario become very cold during the winter, causing the cold water to become denser and sink to the bottom of the lake. Over many winters a reservoir of cold water has built-up, which remains in place even during the warm summer months, providing a year-round supply of cold water.
Initially installed in 2004 the deep lake cooling system is able to provide up to 40% of the city of Toronto’s cooling needs, providing air-conditioning for 100 office buildings or 34,400,000 sq. feet of space. Customers include office towers, legislative and government buildings and sporting and entertainment facilities. The system is able to deliver 75,000 TR (260 MW) of refrigeration capacity.
• 85 million kilowatt hours of electricity annually
• 185 million gallons (700 million litres) of water consumption from cooling towers
• 79,000 tons carbon dioxide from electricity production
• Reduced CFC emissions
All savings are compared to coal-fired electricity.
