A brief description of on-site renewable electricity generating 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.

Wind turbines: six Cleanfield Energy V3.5 vertical axis wind turbines are installed on the roof of the main building along the southern wall of our Whitby campus. The turbines begin spinning and generating energy at a minimum wind speed of 16.2 km/h. Minimal speeds are capable of generating 3.5 kW of power each and 18 kW at speeds of approximately 52.2 km/h. The turbines are utilized as a learning tool for students in the Renewable Energy Technician program. The energy generated is captured and sold back to the grid at a premium rate offered by the Ontario Power Authority’s Feed-in-Tariff.


A brief description of on-site renewable non-electric energy devices:

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.
