Heating, Ventilation and Air Conditioning, HVAC Electricity consumption will consume approximately 40% of the total building’s energy. HVAC dominates the building electricity demand, therefore, improving its efficiency will reduce the peak demand electricity charges.

A significant proportion of building costs comprises of capital and maintenance costs of HVAC equipment. In result, significant capital savings can be made through investing in energy efficient HVAC systems during constructions of new buildings, and strategies exist to optimise the performance of the energy usage in existing HVAC systems, for example, ensuring good maintenance practices.
