November 2023. Our laboratory ice rink is now fully operational! In October 2023, specialized cooling plates and computerized controls were built in BC and transported to TMU. Meanwhile, a 15-foot by 9-foot refrigerated chamber was built to maintain the temperature and humidity of the cooling plates. Ice conditions can now being monitored in real-time with sensors to measure all of the variables involved in high-performance ice making and energy consumption. This laboratory-sized, atmospherically controlled ice rink is the first of its kind ever built for academic research and will support effective risk management and inform optimal, evidence-based ‘green’ arena practices.
