BEST ENVIRO PROJECT
ENWAVE’S DEEP LAKE WATER COOLING INITIATIVE We love our windmill and can’t say enough about the rooftop gardens bursting out everywhere. A huge number of businesses big and small also deserve credit for their conservation efforts. But it’s Enwave, which counts the city as a shareholder, that’s truly shown us the potential for energy savings by taking our largest resource, the lake, and turning its energy into a natural coolant for downtown buildings. Eight major office towers have been hooked up since 2004, including the TD Centre and Royal Bank Plaza. The eco benefits have been astounding. Besides reducing harmful A/C emissions, the system frees some 61 megawatts from the overburdened electrical grid and removes about 79,000 tonnes of carbon dioxide from the air – equivalent to taking 15,800 cars off the road. The best news is that Enwave has barely tapped its potential. It has enough capacity to chill 100 buildings.
