Lake Ontario

OVERVIEW

World-renowned system supplies the downtown core

Enwave’s industry-leading Deep Lake Water Cooling system is the largest of its kind, harnessing the renewable cold temperature of the water at the bottom of Lake Ontario to cool hospitals, data centers, educational campuses, government, commercial and residential buildings. This innovative technology displaces 55 MW of energy a year from the grid – equivalent to powering eight hospitals.

TD Centre

TD logoTD converts mechanical room to leasable penthouse, luxury space

Cadillac Fairview was one of the first customers in Toronto to connect its TD Centre’s six office towers and covered pavilion to Enwave’s Deep Lake Water Cooling system. Now a LEED Platinum-certified complex, the space typically used for mechanical equipment was also converted into a highly sought-after penthouse that has attracted world-class tenants.

Brookfield Place saves more than five million kWh in electricity

It takes a lot of energy to cool more than 2.6 million square feet of office space. Since connecting to Enwave’s Deep Lake Water Cooling system, Brookfield Place has eliminated the need for conventional chiller plants. In 2018, the office complex, which consists of two office towers, as well as the Allen Lambert Galleria and the Hockey Hall of Fame, saved enough electricity to power a small community.

The Well is a visionary mixed-use development by RioCan REIT and Allied Properties REIT, featuring more than 3 million square feet of office and residential space. As part of the development, Enwave invested in an innovative thermal battery that creates and stores energy at night, leveraging off-peak costs. The green and clean technology expands the Deep Lake Water Cooling system to support growth in Toronto’s west end. It also supplies a high-efficiency hot water network to deliver efficient, resilient heating and cooling to The Well and nearby communities.

Keeping patients safe and comfortable at UHN

Part of the University Health Network (UHN), Toronto General Hospital has freed up 20%-30% in capital funds, thanks to Enwave’s Deep Lake Water Cooling system. In addition to greater resiliency and the reliable energy critical to provide health services, UHN can now better focus on its mandate by channeling resources into patient care, research or life-saving equipment. For other nearby buildings, tapping into the hospital’s new system is a progressive way to avoid costly and difficult HVAC retrofits.

PARTNERSHIP

An official partner of the City of Toronto

As part of the TransformTO Climate Action Plan, which outlines ways to improve the city’s health, grow the economy and improve social equity, district energy was identified as a key strategy. In 2017, Enwave was selected as a partner by Toronto’s City Council to help accelerate the implementation of the plan to reduce greenhouse gas emissions and make the city more resilient.
