High Temperature Heating Hot Water Loop Thermal Metering

Supporting Monash University’s campus-wide electrification strategy, we provided the detailed engineering specifications and tender documentation for a high-fidelity thermal metering rollout on the High Temperature Heating Hot Water (HTHHW) loop. The scope involved the strategic integration of thermal meters across 14 primary heat exchangers, facilitating the monitoring of 29 buildings currently served by a centralized 20MW gas-fired boiler plant.

Our mechanical team focused on specifying high-accuracy ultrasonic flow meters and matched temperature sensors capable of maintaining precision within the high-pressure and high-temperature parameters of the existing district heating network. The resulting data set is critical for calculating peak coincident loads and annual energy profiles, which are essential for the right-sizing of future heat pump plant and thermal storage solutions.

We addressed the logistical challenges of integrating these components into existing plant rooms without disrupting ongoing campus operations, ensuring all installations met the university’s rigorous technical standards for data logging and BMS integration. This project serves as a technical precursor to one of the largest industrial-scale electrification efforts in the Southern Hemisphere. By providing a clear empirical baseline of thermal demand, we are enabling the university to de-risk the transition from carbon-intensive fossil fuels to a fully electrified, high-efficiency district heating system. This initiative highlights our expertise in central plant optimization and the data-led decarbonisation of complex institutional infrastructure.
