Set heating, ventilation and air conditioning (HVAC) systems for maximum efficiency

Temperature settings may be adjusted to levels which produce optimal heating, ventilation and air conditioning (HVAC) efficiency while still delivering on comfort.

For every degree you decrease your thermostat when heating or increase your thermostat while cooling, you can save up to 10% off your heating and cooling costs.

Set the temperature to 18–21 degrees in winter and 23–26 degrees in summer; these are the levels recommended by the Australian Government’s Energy Rating website. If your HVAC settings fall outside this range, adjust them and save on your energy costs and carbon emissions.

 How we calculate this

On average HVAC systems account for 36% of energy usage in Victorian SMEs. Setting your HVAC system for optimal efficiency can save 10% of this energy.  36% = (27,916 kgCO2-e X 10%) = 2791.6 kgs
