New insights into air conditioning in the UK

DECC Study on Energy Use by Air-Conditioning

This study comprises several different elements, each directed at improving DECC’s understanding and characterisation of UK electricity consumption by air conditioning in non-domestic buildings; especially that used to support the cooling function (rather than air handling).

These include:

  • 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;
      • a literature search; and
      • the development of procedures to extend the scope of DECC’s product policy model as applied to air conditioning.
