TD Centre converts mechanical room into leasable penthouse, luxury space

Eliminating the need for noisy boilers and bulky chillers, Enwave’s district energy system frees up premium real estate that attracts world-class tenants.

Opportunity

TD Centre leads the way for district energy

Designed by renowned architect Ludwig Mies van der Rohe, up to 21,000 people work in the TD Centre. The property is owned and managed by Cadillac Fairview, the first customer to adopt Enwave’s Deep Lake Water Cooling technology (DLWC). This world-renowned system harnesses the cold temperatures of Lake Ontario to cool buildings in Toronto’s downtown core.

Solution

Cooling with cold water from Lake Ontario

On-site cooling, heating and hot water systems can account for significant electricity and maintenance costs. As an alternative to traditional air conditioning, TD Centre connected to the central Deep Lake Water Cooling system, eliminating the need to install separate systems in each building. District energy has reduced energy and water consumption, improved reliability for tenants and allowed the space typically used for mechanical equipment to be converted into prime leasable square footage.

Results

TD Centre reduces cooling costs by 90%

District energy reduces the need for on-site equipment in each building. Since connecting to the system, TD Centre has achieved LEED-Platinum certification and replaced 13,000 tons of chiller capacity. As a result, the complex uses 90% less electricity compared to that used previously by the chillers.

Successes

First customer on Enwave's Deep Lake Water Cooling system

"At TD Centre, we want to help tenants run their businesses in a healthy and environmentally responsible setting. We’re proud to have been the first to connect to Enwave’s innovative Deep Lake Water Cooling system. Since 2004, this operational resilience strategy has reduced energy costs and improved the comfort of our buildings.”
