The University of Guelph 'The Green Gryphon Initiative' EPC
The University of Guelph is proud of its history of building, maintaining and operating the best possible campus for its community to live, learn and grow. This includes a focus on resource use in an effort to reduce expenditures, carbon emissions and water usage.
The University’s current energy project – 'The Green Gryphon Initiative' – is a $26.2 million investment in sustainability and energy improvements. The project includes many innovative and challenging measures, including a campus chilled water Thermal Energy Storage System - one of the largest utilities projects ever undertaken at the University.
The Green Gryphon Initiative is delivered in partnership with MCW Custom Energy Solutions under an Energy Performance Contract (EPC), wherein MCW provides a guarantee on the total Project Cost and annual Savings over the entire term of the Project.
Featured Energy Management Solution: The Thermal Energy Storage System:
The $15M Thermal Energy Storage (TES) System is an energy performance and infrastructure improvement for the University of Guelph's chilled water district cooling system. It's essentially a huge battery, anchored by a 22 million litre chilled water thermal storage tank that feeds water to the University's Central Utilities Plant and, from there, the campus' chilled water network.
The TES tank is charged at night by the Chillers in the Central Utilities Plant, when Ontario's electricity prices are at their lowest and the grid's carbon footprint is at its lowest. By early morning the next day, the chilled water is ready for discharge to meet the Campus cooling loads.
In Ontario, the Independent Electricity Systems Operator's (IESO) 'Global Adjustment' (GA) mechanism incentivizes large users to proactively manage their electrical demand through demand control strategies triggered by price signals and grid constraint forecasts. The TES System allows the University to shift up to 5MW of electrical demand from daytime peak hours, during which grid and demand charges are highest, to nighttime off-peak hours.
The IESO rewards this shift in demand profile because it enables Ontario to avoid stressing the electricity grid at peak demand times. It also helps reduce the need for added costs such as new distribution and generation infrastructure. At the University, the shift in demand results in a significantly lower electricity bill and an indirect reduction in its campus carbon footprint by using the off-peak electricity predominantly supplied by Ontario's cleaner baseload mix of nuclear and hydro-electric generation.
- A new Thermal Energy Storage system that will meet all of the campus' cooling requirements and reduce peak summertime load electricity demand by up to 5MW. The system uses a 22 million litre chilled water thermal energy storage tank connected to the Campus’ chilled water network. The TES system's tank is charged at night by the chillers, when electricity prices are at their lowest. The chilled water is then ready the next morning for discharge to meet the Campus cooling loads.
- Extensive LED lighting retrofits and lighting controls upgrades, particularly in the Gryphon Centre Athletic Building, where lighting loads were reduced by over 50% while simultaneously improving light level flexibility for indoor sporting activities.
- The project is part funded by University of Guelph's Student Energy Retrofit Fund of $10 per student, per term - a contribution matched by the University on a 1-to-1 basis.
- The student-driven Energy Awareness Campaign - The Green Gryphon Initiative - adds visibility to the project and helps build a culture of energy conservation on campus among students, faculty, and the broader campus community
- MCW also supports other Green Gryphon Initiative projects on campus such as the Raithby House rooftop Solar PV installation and a Bike Shelter complete with a green roof.
