Total energy consumption, performance year:
Clean and renewable electricity (report kilowatt-hours):
| kWh | MMBtu | |
| Imported electricity from certified/verified clean and renewable sources (i.e., bundled green power purchases) | 0 Kilowatt-hours | 0 MMBtu |
| Electricity from on-site, clean and renewable sources (rights retained/retired) | 0 Kilowatt-hours | 0 MMBtu |
A brief description of the certified/verified sources of clean and renewable electricity:
A brief description of the on-site renewable electricity generating facilities/devices:
Clean and renewable thermal energy (report MMBtu):
| MMBtu | |
| Clean and renewable stationary fuels used on-site to generate thermal energy | 10,425.55 MMBtu |
| Imported steam, hot water, and/or chilled water from certified/verified clean and renewable sources | 114 MMBtu |
A brief description of the clean and renewable stationary fuels:
Geothermal energy: we have 18 geothermal wells to store thermal energy (among other things recovered from the heat rejected by the refrigeration systems of the Metro grocery store which is a tenant in our spaces) and reuse it to heat the air and water in the student residences phases 3 and 4, reducing the need for energy. This amount is equivalent to approximately 36% of the total electrical energy consumed by the two residences.
A brief description of the certified/verified sources of clean and renewable thermal energy:
Chilled water: The ÉTS acquires chilled water from the ECCU (Énergir Chaleur et Climatisation Urbaine) plant. This chilled water is produced from low impact hydro-electricity provided by Hydro-Quebec.
Unbundled renewable energy products (report kWh):
| kWh | MMBtu | |
| Purchased RECs, GOs, I-RECs or equivalent unbundled renewable energy products certified by a third party | 0 Kilowatt-hours | 0 MMBtu |
A brief description of the unbundled renewable energy products:
Not applicable given Hydro-Quebec's hydro-electricity.

Data source(s) and notes about the submission:
Additionally, ÉTS has several systems to recover energy and heat to maximize energy efficiency. For example, ÉTS has devices such as reverse flow type recuperators or cassette exchangers installed on ventilation systems. These types of systems have an efficiency of 85%. ÉTS also has plate heat exchangers with an efficiency of up to 75%. Mixed water loops transport the energy dissipated by air conditioning and refrigeration equipment, allowing this energy to be reused instead of being released into the environment. ÉTS also has entorphic wheels with a recovery efficiency exceeding 65%.
