Pioneering the Green Revolution: University of Windsor Unveils Canada’s First Hybrid Chiller

In a groundbreaking move that underscores its commitment to environmental stewardship, the University of Windsor has unveiled Canada’s first dual-drive electric-steam turbine chiller. This pioneering initiative not only marks a significant milestone in the university’s sustainability journey but also sets a precedent for other educational institutions in the country.

On August 24, 2023, the University of Windsor reaffirmed its dedication to fostering a culture of environmental sustainability both on campus and beyond. The unveiling of the new hybrid chiller, a first for Canadian universities, was a testament to this commitment.

Located within the Energy Conversion Centre on Patricia Street, the chiller leverages energy-efficient electricity, complemented by alternative steam energy. This seamless integration of two energy sources promises to significantly reduce the university’s carbon footprint, cutting down as much as 8,300 tonnes of carbon dioxide emissions each year. This is equivalent to removing 2,000 cars from the roads annually.

The hybrid chiller is central to the heating, cooling, and ventilation systems of about 30 buildings across the university’s campus. It is a cornerstone of one of the largest sustainability initiatives undertaken by the university this year, aligning with an ambitious roadmap to reduce greenhouse gas emissions by 45% in the next seven years, and to achieve net zero emissions by 2050.

Gillian Heisz, CPA, CA , UWindsor vice-president of finance and operations, emphasized the university’s “unwavering dedication to environmental stewardship and energy efficiency.” She expressed hope that this milestone project would inspire others to adopt similar measures in the pursuit of sustainability.

The project was brought to fruition with the support of Enbridge Gas, which has been a steadfast partner in the university’s sustainability journey. Representatives from Enbridge Gas were present at the unveiling ceremony, celebrating the installation and announcing incentives of $200,000 in recognition of the university’s participation in the utility’s Commercial Energy Efficiency program.

Since 2018, the university has received over $438,400 from Enbridge Gas, a collaboration that has fostered energy-efficient equipment upgrades and the installation of demand-control ventilation systems, among other initiatives.

Looking Ahead

As the university community looks forward to the unveiling of the Campus Carbon Neutral Master Plan this fall, there is a palpable sense of anticipation and excitement. The comprehensive roadmap outlines bold strategies to further reduce emissions and create a more sustainable campus for generations to come.

Nadia Harduar, MES, CEM, LEED GA, EPt , the University’s sustainability officer, highlighted that they have plans in place to continue to significantly reduce the energy foot print of their operations.

As the University of Windsor takes these important steps forward with the installation of Canada's first hybrid chiller, the integration of a phase change thermal battery could potentially elevate this initiative to unprecedented heights. Phase change materials (PCMs) have the remarkable ability to store and release large amounts of energy, functioning somewhat like a battery but for thermal energy. By incorporating a phase change thermal battery into this system, the university could further optimize energy usage, storing excess thermal energy generated during low-demand periods and utilizing it during peak times.

The addition of a phase change thermal battery like those that Sunamp makes would not only enhance the efficiency of the heating, cooling, and ventilation systems but also foster greater energy independence. By reducing reliance on external energy sources and minimizing fluctuations in energy demand, the university could further diminish its carbon footprint, advancing closer to its goal of achieving net zero emissions by 2050. Moreover, this technology could facilitate a more sustainable management of resources, as it allows for the harnessing of renewable energy sources, such as solar and wind power, storing the energy generated for later use.

The financial implications of this enhancement cannot be understated. The substantial energy savings accrued through the optimized use of a phase change thermal battery could translate into reduced operational costs, making a significant impact on the university's budget over time. This financial efficiency, coupled with the environmental benefits, presents a compelling case for the integration of phase change thermal batteries into the hybrid chiller system.

As the University of Windsor takes bold steps towards a more sustainable and environmentally responsible future, it stands as a beacon of change, inspiring others to follow in its footsteps.
