Описание: Gregg Zonneveld (JCU Estate Office) concluded the presentations with a detailed case study of JCU's central energy plant and 12-megalitre chilled-water thermal storage system, operational since 2009. Designed to flatten peak daytime electrical demand and protect high-voltage feeders, the system charges at night (and increasingly during shoulder periods) using large chillers at high coefficient of performance (typically 7-7.5), then supplies campuses in Townsville and Cairns during the day. Despite changes in electricity tariffs, the approach continues to deliver substantial carbon savings (around 13,500 tonnes CO₂ per year initially) by avoiding low-efficiency daytime operation. He highlighted ongoing relevance, water-use challenges in evaporative cooling towers and the value of continuous monitoring and feedback from campus buildings to maintain performance.
