Toronto’s Metro Hall is the cool place to be
  
Today, the City of Toronto and Enwave Energy Corporation officially opened the valve to begin cooling Metro Hall at 55 John Street with deep lake water.

Enwave’s Deep Lake Water Cooling system uses three intake pipes to bring cold water from Lake Ontario into Toronto to cool buildings. The pipes are 83 metres below the surface of Lake Ontario, where the water temperature is at a constant four degrees Celsius.

“The City of Toronto is doing its part to reduce energy demand by implementing the Deep Lake Water Cooling system,” said Deputy Mayor Joe Pantalone. “This project alone will reduce the City’s electricity peak demand use by one-and-a-half megawatts each year. That’s enough electricity to power 174 homes.”

Along with implementing Enwave’s Deep Lake Water Cooling system, the City is upgrading its facilities to make them more energy efficient. So far, over 140 facilities -- arenas, community centres, fire halls and office buildings -- have been upgraded to save money and energy.

Metro Hall is the first municipal facility to be added to Enwave’s Deep Lake Water Cooling system, and the 46th building signed on to the system. At its last meeting, Toronto City Council approved staff to proceed with plans to add Old City Hall at 60 Queen St. W., to the pipe by 2008 and to look at the feasibility of connecting City Hall.

At full capacity, Enwave’s Deep Lake Water Cooling system can service more than 100 office buildings and reduces electricity use that is equivalent to 6,800 homes. As a result, about 79,000 tonnes of carbon dioxide that would otherwise be produced by conventional air conditioning annually, will not be emitted into the air. That is equivalent to taking 15,800 cars off the road.

“This is one of the cleanest and most cost effective ways to cool a building,” said Dennis Fotinos, president and CEO of Enwave Energy Corporation. “Using a renewable source of cold water from the depths of Lake Ontario to provide air conditioning and cleaner drinking water is not only environmentally friendly but also a good business decision. We are pleased to have the City of Toronto join other reputable property managers already on the system.”

Enwave serves 51 per cent of the potential heating market and provides heating and/or cooling services to over 140 institutional and commercial buildings in downtown Toronto. Enwave was reconstituted in December 1999 as a private corporation with OMERS (the Borealis Penco Fund) and the City of Toronto as shareholders.
