City of Toronto Launches Cool it, Power it, Grow it - The Greening of Toronto City Hall
Today Mayor David Miller officially announced The Greening of Toronto City Hall, which is now cooled by Deep Lake Water Cooling (DLWC), powered by green power, and will be improved with the construction of a green podium roof.

”The City of Toronto is committed to showcasing City Hall as a sustainable building to reduce its environmental footprint,” said Mayor Miller. “We’ve set an example of what we can do as leaders in the fight against climate change.”

To “Cool It”, City of Toronto has installed a cooling system at City Hall with Enwave’s Deep Lake Water Cooling (DLWC) to replace the conventional air conditioning system. DLWC will reduce electricity consumption by approximately 1.9 million kilowatt hours annually. It will also reduce Cabon dioxide (CO2) by 325 tonnes (a 75 per cent reduction in CO2 emissions as compared to conventional chillers). This is equivalent to taking 70 vehicles off the road.

To “Power It”, City Hall and Nathan Phillips Square are now “Bullfrog powered”. Low-impact, renewable electricity from Bullfrog Power will help the City reduce its emissions footprint by over 4,000 tonnes of C02. In Ontario, Bullfrog Power provides the highest quality green electricity available from EcoLogo-certified low-impact wind and hydro facilities located right here in the province. The City’s commitment will help to advance the development of new renewable energy in Ontario.

To “Grow It”, construction on a new green podium roof at City Hall has begun. The green podium roof will be Toronto’s largest, publicly accessible green roof. It will be a new urban oasis in the heart of the city which will include landscaped gardens, a courtyard framing the Council Chamber, a podium terrace and new walkways. The podium roof will be planted with a modular green roof system that involves the use of trays of vegetation which are pre-grown in local greenhouses and are seamlessly installed. The green podium roof is expected to open late in 2009.
