Case Study: Scotiabank Centre reduces carbon footprint with Trane Commercial thermal storage solution

Scotiabank Centre Scores Big with Thermal Storage Solution

The Scotiabank Centre, a major multipurpose arena in Halifax, faced a critical challenge as its aging HVAC and ice plant refrigeration systems were failing. These ammonia-based systems were inefficient, costly to maintain, and leaked water. The center needed a reliable, sustainable solution to reduce its carbon footprint and operational costs while improving ice quality, aligning with Halifax's net-zero goals. They turned to their long-term partner, Trane Commercial, for a solution.

Trane Commercial implemented a large-scale ice thermal storage system using its Ascend air-cooled chillers, CALMAC ice storage tanks, and Opteon refrigerant. This system charges with ice overnight to avoid peak energy pricing. The results include significant reductions in energy costs and water usage, improved staff safety, and an estimated saving of 14,000 tons of CO2 over the project's life. The new system is easier to maintain and provides a consistently high-quality environment for both ice and non-ice events.
