A brief description of the on-site renewable electricity generating facilities/devices:
Solar panels: DC expanded the Whitby campus in 2009 to build capacity. The 20,000-square-foot expansion allowed for 350 solar panels to be installed. The photovoltaic cells provide clean energy back to the grid with a combined capacity of 72 kilowatts of electricity.

The new CfCE LEED Gold building also includes 64 rooftop solar panels with a capacity of 20.8 kilowatts of electricity.

Clean and renewable thermal energy (report MMBtu):
MMBtu
Clean and renewable stationary fuels used on-site to generate thermal energy 91 MMBtu
Imported steam, hot water, and/or chilled water from certified/verified clean and renewable sources 0 MMBtu

A brief description of the clean and renewable stationary fuels:
Geothermal: the Whitby campus expansion incorporated a new ground source heat pump (GSHP) system to provide adequate and energy-efficient heating and cooling to the expansion. The GSHP system uses 70 tonnes of refrigeration cooling-load pumped through 32 U-shaped pipes installed approximately 150 m underground. Depending on the season, the system circulates to transfer hot or cool air into the building.
