Toronto’s City Waterfront Building Energy Retrofit Wins a 2024 Clean50 Top Project Award

Twenty-four innovative Canadian sustainability projects have been recognized with a 2024 Clean50 Top Project Award – including Toronto’s City Waterfront Building Energy Retrofit. Canada’s Clean50 Top Project Awards are amongst those, announced annually by Delta Management Group and the Clean50 organization, to recognize the best sustainability-oriented projects completed in Canada over the prior two years.  Projects are chosen based on a five “I”s criteria:  Impactful, Innovative, Inspiring, Informative and readily Imitated.”

Clean50 Top Project Award

Ecosystem is proud of our work together with the City of Toronto to deliver stage 3 of this project, a deep energy retrofit focused on hydrothermal technology and transformational results.

City’s Pilot Retrofit Turned World-Class Model of Sustainability

The City Waterfront Building (CWB) is an innovative energy retrofit project achieving ambitious sustainability targets through cutting-edge renewable technology. The project employed a closed-loop hydrothermal system – the first in Lake Ontario and among the first in Canada. Using heat pump technology and electricity, the system provides 100% of the building’s heating and cooling, eliminating natural gas use. A solar PV system works in tandem, offsetting the building’s electricity use. The outcomes are transformational: the CWB uses 71% less energy, emits 83% fewer Scope 2 GHG emissions, enhances building comfort, generates clean, decentralized electricity, and serves as a world-class model for building owners exploring hydrothermal technology.
