Heating, Ventilation and Air Conditioning (HVAC)
A typical Heating, Ventilation and Air Conditioning (HVAC) system consists of plant equipment (chillers, boilers etc.) which transfer energy via air, water or a refrigerant to air distribution systems consisting of a series of fans and coils. These distribution systems are usually called air handling units (AHUs). The AHUs then use this energy to warm or cool the air that is supplied to the office space.
System Selection – Signifcant energy savings can be realised through optimal system selection. For example, a Variable Air Volume (VAV) AHU regulates the volume of the supply air to the spaces depending on the amount of heating or cooling required. This system allows for greater control and reduces airfow rates, which reduces overall fan energy consumption. This greater control may also reduce energy wastage associated with re-heating, where the heating system counteracts the cooling system.
Plant Selection – Plant selection can greatly affect the overall energy consumption of a building. For example, condensing boilers – used for the provision of heating hot water – can have gross effciencies over 90%.
Differences in efficiency can have a radical impact on energy consumption. For some buildings the before and after consumption of an individual end use following an energy efficiency upgrade can vary. Upgrading existing fans, motors, gas systems and boilers can radically reduce the total energy consumption of a facility resulting in enormous energy savings.
