Sustainability – Oztech Net Zero Carbon Strategy by 2030

The Role of Buildings in Climate Change

Buildings are responsible for approximately 19% of Australia’s total energy consumption and 18% of direct carbon emissions. Within those buildings, HVAC systems can account for up to 80% of energy use — making them one of the single largest contributors to emissions in the built environment.

That’s where Building Management Systems can make a real impact.

Through advanced control strategies, intelligent logic, and precise tuning, BMS can significantly reduce HVAC-related energy use — improving both environmental performance and operational efficiency.

But unlocking that value requires more than standard setup. It takes intimate knowledge of the building, how it behaves over time, and how its systems interact with one another.

At Oztech, this is our core expertise. We work across a wide range of commercial, retail, and industrial buildings to help owners and operators achieve NABERS improvements, reduce energy waste, and move confidently toward net zero goals.
