Cresstec has completed the first phase of an HVAC optimisation project at La Trobe, working alongside ASM Chilltech and BGIS. The project began with HDAC monitoring, adding another layer of visibility to an already well-managed HVAC system. An Installed HDAC Supporting Our Advanced Sensor Suite The existing controls and operating schedules had been set up correctly. But large HVAC systems have multiple layers of control, local equipment logic and factory default settings. Wh

Energy-saving claims are easy to make. Proving them is harder. Measurement & Verification provides a recognised framework for agreeing how savings will be determined accounting for weather, operating conditions and what would reasonably have happened without the project.

Independent CSIRO testing and a national DCCEEW bench-testing program confirm Cresstec’s expertise in refrigerant charge optimisation, proving how preventable HVAC faults increase energy use, emissions and costs. Discover why Cresstec is setting new industry standards in performance and maintenance.

Commercial buildings are under growing pressure to cut operating costs, strengthen energy performance, and align with tighter decarbonisation expectations. Yet across Australia, one of the biggest and least understood expenses is hiding in plain sight. HVAC systems that appear “off,” properly scheduled, or fully optimised often continue running in the background, cycling unnecessarily or even working against themselves. This silent behaviour burns electricity, inflates emissi
