Large scale energy surveys in the UK retail sector.
The UK retail sector accounts for around 18% of total non-domestic UK building floor space and a significant proportion of UK energy use. Much of the information available about energy use was collected several years ago, much of it from the major 'Four Towns' study carried out in the early 1990s. Since then there have been many changes in the sector, with a shift to out-of-town shopping, a changing mix of high street shops and increasing use of air conditioning. To improve the information in this area, large-scale, low-level surveys of about 600 retail premises in Stamford, Leicester, Chesterfield and London were carried out, spanning a range of town sizes and types of shopping area. Summer surveys in warm weather to establish air conditioning were followed by winter surveys to establish heating practices. The purpose was to establish the extent of air conditioning, door opening practices, use of air curtains and types of lighting, and relate these to location and type of premise. Data, including digital photographs of every premise, were stored in a relational database. About 50% of premises were found to be air conditioned, with higher proportions for city centres, larger premises and chain stores. In summer, many air conditioned premises had open doors with no air curtains, causing additional cooling demand. Estimates of heating and cooling wastage have been made using computer simulation and empirical equations to model air flow through open doors with an inside to outside temperature difference. Another technique that has been explored is the use of Infrared Imaging, principally to research covering large urban areas in a more expedite way. State-of-the-art cameras were used for technology appraisal. © 2006 RICS, The Bartlett School, UCL and the contributors First published.
