As part of the City of Toronto’s ambitious Transform TO and Net Zero Strategy, its Comprehensive Energy Retrofit Program seeks to drastically reduce GHG emissions and energy consumption in City buildings, while maximizing opportunities for renewable energy. The EMS HQ retrofit is one of three pilot projects within the program.
Constructed in 1979, the EMS HQ is a series of interconnected one to three-storey buildings housing the Toronto Paramedic Services and Fire Services and the Toronto Police Services. It is also one of the most critical assets in the City’s portfolio. As such, special consideration was given to the design and construction of the project so as not to interrupt critical operations and to ensure safety during implementation – which is no small task when drilling boreholes for a geothermal system in a tight, urban environment. In close collaboration with the City and its stakeholders, Ecosystem developed a solution including ground- and air-source heat pumps as well as solar PV – renewable measures that will not only simplify operations and improve occupant comfort, but also maximize the reduction of GHG emissions and energy use at a reasonable cost.
Once completed in winter 2022, the EMS HQ energy retrofit will reduce the facility’s GHG emissions by 73%, its energy consumption by 55%, and address all its critical asset renewal needs.
