PERFORMANCE INDICATORS FOR ENERGY EFFICIENT SUPERMARKET BUILDINGS

摘要

Performance indicators are needed to transform available measurement data into knowledge on the energyrnefficiency of a supermarket building. Such indicators are e.g. the supermarket size, the opening hours, thernoutdoor climate and applied energy saving options. When the energy use is related in to the supermarket size,rnopening hours, and other performance indicators, it should be possible to appreciate the energy use of thernsupermarket: is it relatively high, normal, or relatively efficient. IEA HPC Annex 44 “performance indicatorsrnfor energy efficient supermarket buildings” searches for performance indicators that will allow to evaluaternenergy efficiency of existing single supermarkets, supermarkets within one chain, supermarkets acrossrndifferent chains and even supermarkets in different regions or countries. Based on new data from thernNetherlands, this paper investigates the relation between sales area, opening hours and yearly energyrnconsumption, and discusses other aspects that are needed to understand observed data.
