"---" indicates that no data was submitted for this field

Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 37,173 MMBtu 36,245 MMBtu
Electricity from on-site renewables 0 MMBtu 0 MMBtu
District steam/hot water (sourced from offsite) 0 MMBtu 0 MMBtu
Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) 52,658 MMBtu 47,601 MMBtu
Total 89,831 MMBtu 83,846 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year Nov. 1, 2016 Oct. 31, 2017
Baseline Year Nov. 1, 2015 Oct. 31, 2016

A brief description of when and why the building energy consumption baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):
---

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 61,487.50 Gross Square Metres 61,487.50 Gross Square Metres

Source-site ratio for grid-purchased electricity:
2.05

Total building energy consumption per unit of floor area:
Performance Year Baseline Year
Site energy 0.14 MMBtu / GSM 0.13 MMBtu / GSM
Source energy 0.19 MMBtu / GSM 0.18 MMBtu / GSM

Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
0

Degree days, performance year (base 65 °F / 18 °C):
Degree days (see help icon above)
Heating degree days 4,769 Degree-Days (°C)
Cooling degree days 92 Degree-Days (°C)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 311.40 Square Metres
Healthcare space 1,254 Square Metres
Other energy intensive space

EUI-adjusted floor area, performance year:
701,921.06 Gross Square Metres

Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
14.63 Btu / GSM / Degree-Day (°C)

Documentation (e.g. spreadsheet or utility records) to support the performance year energy consumption figures reported above:
---

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency (e.g. outreach and education efforts):
---

A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):

Our lights are motion- sensored so that if the room is vacant, the lights will turn off. All of our student and public computers are automatically turned off at night (about 70% of the computers on campus).


A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

Our West campus uses 100% LED lighting, and we are in the process of transitioning all of our lights in South and North campuses to full LED lighting as our flourscent blubs burn out. In 2018, we will be installing 100% LED lights in our 3 storey Parkade.


A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
---

A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
---

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment and systems with high efficiency alternatives (e.g. building re-commissioning or retrofit programs):

All of our appliances in food services areas are Energy Star certified. We recently installed EndoCube thermometers in our fridges to increase energy efficiency: http://www.endocubeuk.com/endocube_refrigeration.html

Additional documentation to support the submission:

Our South Campus uses district heating which is more efficient than natural gas. In this system, pipes bring warm water from ENMAX's District Energy Plant to heat the College. This helps us save the energy equivalent to taking 100 cars off the road each year for 25 years.
