Toronto-Dominion Centre’s (TD Centre) fourth annual sustainability report, released this week, shows the complex has surpassed new levels of achievement with a 3.8 per cent reduction in energy use—about $800,000 in tenant cost savings.

Comprised of 4.5 million square feet, all six towers became LEED Platinum-certified last year, having to adhere to firm criteria for energy and water efficiency, waste management and indoor environmental quality.

For 2015, the complex attained 3.9 per cent lower water consumption, conserving almost 14 million litres, along with an 81 per cent waste diversion rate, saving five million kilograms of waste from landfills and $300,000 in associated waste removal fees.

“Everything we’ve been able to achieve has been the result of meaningful collaboration with our tenants, who continue to encourage us to build on our environmental efforts,” said David Hoffman, general manager of TD Centre. “We will continue to aim for even healthier and greener buildings and to invest in new technologies and innovative tenant initiatives to raise the bar for sustainability even higher.”

During the past four years, TD Centre has dedicated $200 million to greening and revitalization investments and introduced its Occupant Engagement Program, which encourages tenants to help meet progressive consumption targets. So far, a 16.8 per cent reduction in energy use, a 16.7 per cent decrease in water consumption, and a diversion rate of 19 million kilograms of waste from landfill, has pushed the complex to be a leader among green buildings around the world.

Future targets include a sustained annual 2.5 per cent decrease in energy consumption, a 2 per cent decrease in water consumption and a 90 per cent waste diversion rate.
