York University’s energy management program helps navigate hot weather sustainably

In circumstances of extreme weather – such as heat warnings in summer due to soaring temperatures – Facilities Services works hard to ensure the York University community can continue to comfortably learn, teach and work on our campuses, while balancing the University’s commitment to sustainability in its operations.

Unseasonably high temperatures generate unprecedented demand on the provincial energy grid, leading to more energy use, higher emissions, inflated costs and strain on the grid. As a result, York U implemented a peak demand management program in the summer of 2023 – an effort to uphold its commitment to support a sustainable energy system in Ontario. This program, which has been implemented at universities across the province, requires York U to reduce its energy use in alignment with peak demand days to eliminate emissions, save costs and reduce strain on the grid.

Through participation in this program last summer, it is estimated that the University avoided 22,000 tonnes of carbon emissions and saved $3.8 million in energy costs by reducing its energy use by eight megawatts on peak days over the summer months. That is equivalent to taking 24,713 cars off the road or eliminating the consumption of over 34-million litres of gasoline.

“Global warming has forced us to think differently about how we heat and cool our buildings,” says Brad Parkes, assistant vice-president of Facilities Services. “In Facilities Services, we’re constantly looking at the data to see how we can optimize our systems, work with the provincial grid instead of against it and contribute to sustainability and cost savings goals through our operations. The concept of the peak demand management program is simple, but it has real impact that will continue to grow.”

To ensure comfort on York U’s campuses during the program, Facilities Services cools buildings to a lower temperature overnight, with the goal of retaining the cooler air throughout the day when the temperatures are elevated. Those efforts can be extended if community members keep exterior doors, windows and blinds closed to keep the cold air in. For those with workspaces adjacent to a space that has air conditioning, such as a hallway, keeping doors ajar to promote circulation might be helpful. Turning off lights not in use, or using natural light, is another way to help with unnecessary heat generation.

Facilities Services also references the classroom booking information from the Office of the University Registrar to strategically match air conditioning to buildings with occupancy and reduce air conditioning in buildings without occupancy. Special attention has also been given to buildings that require consistent cooling due to equipment, technology and ongoing research.

Community members with concerns or questions about the temperature in their space should get in touch with the Work Control Centre by emailing facilities@yorku.ca or calling 416-736-2100 ext. 22401. Managers should also refer to the Hybrid Work Policy and Hybrid Work Procedure regarding discretion and flexibility to adjust hybrid work agreements as necessary.
