Energy consumption data forsupermarket stores have been obtained and compared with data from otherstudies. Correlations and trends from the data have been analysedto investigate what influences energyconsumption in a retail store. Energy consumption of the supermarkets was well correlated with both salesfloor and total floor area. Once floor area was taken into account, there was no difference in energyconsumption between different store types. There was a positive correlation with store age and hours open,however, it was much smaller than those for floor area. The mean specific energy consumption (SEC) of thedata set was 566kWh.m2.year-1 based on electrical energy consumption and sales floor area. This rose to 759kWh.m~2.year~(-1) when gas was included. From other studies the SEC varied from 407 to 1700kWh.m~2.year~(-1)based on electrical energy consumption.
