Ookwemin Minising Climate Positive Assessment

Waterfront Toronto is building Ookwemin Minising (Villiers Island), a new mixed-use, climate positive neighbourhood that offsets more greenhouse gas emissions than it emits, all onsite. Located on waterfront industrial land adjacent to downtown Toronto, the community must be highly energy efficient and generate renewable energy to accomplish its goal.

SSG used ScenaLocale to show Ookwemin Minising could become climate positive by building highly energy efficient buildings powered by an onsite deep geothermal energy system, building-integrated solar PV, and battery storage. The system will generate more thermal energy than the community requires so it can supply clean energy to adjacent neighbourhoods.

Climate positive solutions were identified by modelling mixes of all manner of energy generation and storage technologies, and energy efficient building designs. All mixes were financially modelled to find the best balance of costs and meeting energy needs onsite. Even if some grid energy use and gas vehicles persist by 2045, emissions from these sources will be amply offset by the neighbourhood’s deep geothermal energy facility.
