Measuring Energy Usage
A number of factors determine the energy use of any air conditioning system, including:-
Latest Technology
All leading air conditioning manufacturers are looking constantly for greater improvements in energy efficiency not only, of course, to promote their own products but also in recognition of the various EU and UK initiatives to manage climate change.
New Legally Compliant Refrigerant
As one example, HFC refrigerant R410A has a zero ozone depleting potential and up to a 30% increase (if not more) in efficiency can be achieved with inverter air conditioning using this refrigerant in comparison to older style R22 equipment. Increased efficiency equates to less energy consumption, reduced energy costs and lower CO2 emissions.
COP and EER
The terms COP (Coefficient Of Performance) and EER (Energy Efficiency Ratio) describe the heating and cooling efficiency of an air conditioning system. Thus, if a system generates 5kW of heat from a 1kW electrical input, its COP is 5.0; similarly, 4kW of cooling from the same electrical input equates to an EER of 4.0. The higher the COP and EER, the more energy efficient is the equipment.
Enhanced Capital Allowance (ECA) Scheme
The ECA Scheme is designed to encourage businesses to invest in low carbon energy saving equipment (not least air conditioning) that meets specified Government criteria and is part of the UK’s programme to manage climate change. By allowing up to 100% of the investment to be offset against taxable profits in one year, the Scheme can bring significant financial benefits to businesses as well as improving their energy efficiency and carbon emissions.

A number of factors determine the energy use of any air conditioning system, including:-
- The design, layout and operation of the building
- The required indoor temperature and air quality
- The heat generated internally by lighting, equipment and people
- The design and efficiency of the air conditioning plant itself
- Regular maintenance ( without which energy consumption can increase by up to 30%)
- The operating times of the air-con equipment and proper use of its controls
