Energy use by air conditioning

This study looked at improving DECC’s understanding and characterisation of UK electricity consumption by air conditioning in non-domestic buildings.

This study for the former Department of Energy and Climate Change (DECC) looked at energy use by air conditioning and comprises several different elements. It focused on systems in non-domestic buildings to support cooling function, rather than air handling. It aimed to improve understanding of UK electricity consumption by these systems.

Key findings

Analysis of measured consumptions in offices, including:
- Annual electricity consumption
- Relationship of demand with external temperature
- Peak demand and annual load factors.
Examination of the contents of air conditioning inspection reports and energy performance certificates, including:
- Distributions of reported efficiencies and calculated consumptions, by building and system type
- Literature search
- The development of procedures to extend the scope of DECC’s product policy model as applied to air conditioning.
