A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
The geothermal field and Energy Innovation Centre (EIC) project is part of the ongoing transformation of Durham College’s (DC) energy infrastructure to support and implement sustainably focused initiatives on campus.
Located underground at the Oshawa campus, DC’s geothermal field harnesses 550 tons (1.9 megawatts) clean, sustainable geothermal power, which is then processed through the EIC and sent to the Gordon Willey building to fuel its energy needs.
The bright, modern EIC also provides an exhibit-like atmosphere where students and visitors can learn more about how the geothermal system works through interactive touch screen monitors, which features system diagrams and performance metrics. Additionally, a real-time energy dashboard provides insight on campus energy savings and the reduction of associated greenhouse gas emissions.
The EIC also acts as a living lab, allowing faculty from selected programs to incorporate geothermal technology into their curriculum and provides students with a unique experiential learning opportunity as they observe how green-energy technologies work.
The geothermal field and EIC were completed in partnership with Siemens Canada, who provided valuable industry knowledge and contributed as the primary contractor for the project.
A brief description of energy use standards and controls employed by the institution:
Durham College has a building automation system which regulates temperatures and allows setbacks while the room is not occupied. Aim to meet ASHRAE standards (55-1992)
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
All parking lot and roadway lighting upgrade from MH to LED
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
