Increasing the temperature setpoint by 1oC will reduce the amount of power your air conditioner uses by up to 10 per cent, saving 200 kg of carbon pollution.
The setpoint defines the temperature level required to make an air-conditioned space comfortable. When the temperature rises above or drops below the setpoint, the system's control measures start working to return to that level. The lower the setpoint in summer, the harder the system has to work.
In winter, the reverse is true – the higher the setpoint, the harder the system works.
The savings don't stop with adjusting the setpoint. The performance of heating, ventilation and air conditioning (HVAC) equipment deteriorates over time, so a well-designed maintenance program can yield enormous savings depending on the size of your business – a system with a 100kW chiller could save 10,000 kg of carbon pollution annually.
