A brief description of the institution’s GHG emissions reduction initiatives:

In 2019, Durham College celebrated the opening of it's new Energy Innovation Centre. 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.
