Part 2. Reduction in source energy use per unit of floor area
Baseline year energy consumption
STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.
| kWh | MMBtu | |
| Imported electricity | 155,902,086 Kilowatt-hours | 531,937.92 MMBtu |
| Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) | 0 Kilowatt-hours | 0 MMBtu |

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Engagement campaigns to ensure the community understands the impact of their personal decisions. Student-driven competitions to reduce energy consumption in residences.
A brief description of energy use standards and controls employed by the institution:
New construction and renovations projects are designed to accommodate low temperature hot water to minimize GHG impact.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
All new/renovation projects require LEDs as part of the project specification. Large and special-use areas are targetted for lighting retrofits and smaller areas are updated with renewal.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
a) Passive solar heating: New constructions are designed to balance solar exposure and thermal energy performance. New buildings are also equipped with blinds, to limit the solar exposure during summer months, while still allowing light into the buildings.
b) Our newest building was designed with photosensitive windows, which will automatically adjust their tint based on date and time, as well as weather.
b) Our newest building was designed with photosensitive windows, which will automatically adjust their tint based on date and time, as well as weather.
A brief description of co-generation employed by the institution:
