This data was collected as part of a PhD project to analyze the performance of a large-scale non-domestic heat pump installation. The building in question was the Hugh Aston building at De Montfort University, Leicester, UK. High frequency data have been collected during the initial three years of operation of the system. This data has been collated to allow seasonal performance factors to be derived and also detailed analysis of heat pump, circulating pump and control system operation. The data set includes minutely ground loop and heating/cooling loop fluid temperatures and flow rates. The data set has been used to validate models and design procedures for vertical borehole ground heat exchanger arrays
