On 25 July 2016, BRE published a report that sheds important light on electricity usage by air conditioning in UK offices and retail environments.

Comprising the findings of a two-year study commissioned by the Department of Energy and Climate Change (DECC) - now subsumed within the newly-formed Department of Business, Energy and Industrial Strategy - the report provides key insights into how the energy is being used and the factors influencing consumption.

The aim of the study was to improve the DECC's understanding of UK electricity usage by air-conditioning (AC) in UK non-domestic buildings.

The study, led by Dr Andy Lewry, BRE's principal consultant, included:

* Analysing existing cooling demand and consumption data.
* Assessing air conditioning inspection reports and energy performance certificates.
* Reviewing literature on trends in air conditioning usage and the possible future impacts of new technology.
* Developing procedures to extend the scope of DECC’s product policy model.

With the research informing objectives ranging from estimating the potential for energy efficiency to how uptake of energy-efficient appliances can be accelerated, the main findings and outcomes include:

* Cooling in air conditioning systems may account for around a tenth of total UK electricity consumption.
* Heat-waves are becoming more frequent across the UK and in the South-East of England, the number of heat-wave days per year increased from 5 in 1961 to 17 in 2003.
* The proportion of buildings with air-conditioning is increasing. The study estimates that that, in 2012, some 65% of UK office space and 30% of UK retail space was air-conditioned.
* The study estimates that cooling in offices typically uses around 40 kWh/m2 per year.
* Air conditioning is frequently used even when buildings are unoccupied, for example in the evenings and over the weekends.
* The analysis of Energy Performance Certificates (EPCs) indicates that over half of air conditioning systems in the UK are split systems. Although only 10% of EPCs have AC recommendations; these mostly relate to more efficient equipment, including variable speed drives, and reducing air leakage from ductwork
* An analysis of the recommendations in air conditioning inspection reports, which tend to be generic with the focus on improving controls and maintenance.
* Recommendations for updating the key inputs into DECC's existing product policy model of air conditioning electricity demand and development of an algorithm to estimate peak and monthly demand to supplement it.

BRE has also put together a dissemination plan aimed specifically at air-conditioning designers and technicians, building managers and smart system designers
