Energy efficiency analysis and benchmark in grocery stores: Results of a short-term sub-metering measurement campaign

The objective of this research is to create a methodical approach for the energetic analysis and comparison of grocery stores using a mobile measurement-system in on-site investigations. Al-tough energy measurement technology is a useful tool for the structured analysis of enterprises, there’s little research on benchmarking analyses based on energetic data from a mobile measurement-system. In this context, this study analyses three grocery stores (supermarkets) focusing the energetic comparison and determination of energy performance indicators (EnPIs). This research found that the energetic data of the measurements on a sub-sectional level provide relevant data for a benchmarking-system and the determination of EnPIs. The scientific approach outlined in this work aims the quantification of energy saving potential and energy benchmarking analyses and shall be transferable to enterprises in any industry.
