A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
A page is dedicated on the Office of Sustainability's website to energy saving tips at school, work and home. The energy awareness campaign was heavily promoted on social media.
As part and parcel of our sustainability initiatives, and in support of Canada’s commitment to a reduction in greenhouse gas emissions, Humber has recognized the importance of examining energy and water consumption more strategically and in 2015 authorized the development of an Integrated Energy Master Plan (IEMP) looking forward to 2034. The IEMP team is being challenged to create a plan that meets the following goals for Humber College:
- Offer world-class courses addressing competitive and integrated energy, water and climate solutions while acting as a living laboratory for our students
- Create a campus-wide energy culture by engaging both staff and students via education/events
- Reduce energy use by 50% per square foot by 2034
- Reduce water use by 50% per student by 2034
- Reduce greenhouse gas emissions by 30% by 2034
A brief description of energy use standards and controls employed by the institution:
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Humber developed aggressive lighting standards. Our lighting retrofit projects go further than a simple one for one LED retrofit to include full lighting redesign to reduce the number of fixtures, aggressive lighting energy density targets, and a standardized network lighting control system. We have been seeing energy savings above 60% from our T8 system.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
Humber is currently installing a large geothermal field as part of a large new construction project at our Lakeshore Campus. With 100 geothermal wells over 800 feet deep, it is how the building will achieve net zero carbon status. At our North Campus we have conducted a geothermal survey to identify the resource, and have designed our new district energy project to be able to take a geothermal field as part of a future project.
A brief description of co-generation employed by the institution:
After much consideration Humber has decided not to install a cogeneration system. The Ontario electrical grid is so clean that a cogen will drive carbon emissions on campus much higher than they are now. Instead we are implementing a load shedding strategy to replace the financial payback of the cogen.
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
Humber has set efficiency standards for new equipment, and always incorporates efficiency in the replacement decision process. It is a part of our Integrated Energy Master Plan.

Data source(s) and notes about the submission:
The discrepancy between the performance and baseline year is due to the energy efficiency programs implemented at the college in recent years, along with the effects of the COVID-19 pandemic. A smaller amount of energy was consumed on campus during the reporting time period due to the stay-at-home orders, and this is reflected in the data.
