HVACs are subjected to more misuse than any other type of equipment, and controlling how and when it is operated can save significant amounts of electricity. Implementing the following easy guidelines– and asking staff to support this energy efficiency intervention – can make a significant contribution towards optimising energy usage in buildings and facilities, and reducing electricity costs in business:

• Set air-conditioners’ average temperature at 23°C 
• Close windows while air-conditioners are running.
• Only switch on air-conditioners in offices, rooms and sections of buildings that are occupied.
• Switch off units30 minutes before the end of the working day.
• Adjust blinds and curtains in rooms that receive direct sunlight, which helps to keep rooms cool and postpone switching on air-conditioners.
• Conduct proper maintenance to ensure that all HVAC system components – including motors, pumps, fans, compressors, ducting and filters – are intact and work efficiently.
• Consider replacing old systems as newsystems offer enhance control functionality and high levels of energy efficiency.
• Create awareness amongst employees and individuals responsible for the control of HVAC systems not controlled via a building management system.
