Effective Low-cost Energy Saving Strategies in Supermarkets:An UK Case Study
Supermarket buildings are complex energy systems that require careful study to make sure they perform in a sensible manner.The retail pressure of delivering stores in a short time makes engineering commissioning teams prone to mistakes and therefore,despite stores being newly built and carefully designed,their systems are not ideally set up; thus making the building underperform from day one.Consequently,energy savings are within easy reach if an effort is made to re-evaluate stores shortly after their opening date.This paper focuses on how adequate monitoring and good housekeeping can lead to effective energy saving strategies for a better management of services such as lighting,refrigeration,heating and ventilation.Additionally,a focused effort in curtailing energy use in supermarkets can also seriously reduce operational carbon related emissions; an ever-growing concern for retailers in an environment where sustainability practice is highly valued by consumers.A case study of a 35,000 ft2 supermarket located in the south-east of England serves as a vehicle to present and quantify effective,low-cost energy saving strategies.Extensive monitoring capabilities allow us to set a benchmark for all systems which then serves to assess the effectiveness of trials performed.Trials consist of: a)enhancing the dimming capabilities of the lighting system by improving sensor location and code,b)improving settings of fans and boiler system that reduce heating and ventilation requirements,and c)advocating the proper use of night-blinds in cabinets coupled with suction optimization of compressors that save energy use in the refrigeration system.All of these live trials have the feature of working closely with store staff and management,specialised contractors and academics.The synergy of parties allows the energy trials to succeed since aside from having solid technical foundations they have the full support from the people that work day in and day out in the supermarket–thus,neither commercial practices nor customer shopping experience is negatively affected by the energy trials.Overall,total store performance of the case study improved 15%against its benchmark,significantly reducing the carbon footprint and energy bills of the building.Furthermore,all the trials have quick payback periods with the virtue of being easy to roll-back and roll-forward across the estate; therefore implementation of such practices should be at the core of any energy efficiency program any food retailer embarks upon.
