HVAC (Heating, ventilation and air-conditioning)

It is estimated that 40–52 per cent of total energy consumption in commercial buildings is being used by HVAC systems.

In office buildings HVAC is estimated to be responsible for an average 43 per cent of the electricity used.

Ensuring HVAC systems are well designed for operational needs, and adopted measures to improve efficient operations such as correct zoning, fitted with economisers and/or heat exchangers, installing timers and sensors, and adjusting temperatures can reduce energy consumption of HVAC equipment by up to 40 per cent.
