The study aims to investigate the effects of a remote energy management service to the energy consumption of retail buildings. The study focuses on analysing the changes in energy consumption after the implementation of a facility service concept where building processes are optimized with a remote energy management system. The paper seeks to demonstrate that remotely operated building management practices, which allow high competence service for all facilities, have a positive impact, beyond traditional facility services, on energy and environmental performance of buildings.
The research analyses the metered energy consumption of two retail building portfolios comprising altogether 44 properties. Additionally, secondary data are collected from archive reviews, observation and interviews.
The research shows that remote energy management service reduced the total energy consumption during the two-year service period by 12 and 6 per cent depending on the portfolio. Electricity consumption was found to decrease by 7 per cent and heating energy by 26 per cent on the average in the first portfolio, and 7 and 4 per cent in the second one, respectively.
Variation between buildings was found to be relatively high as the individual characteristics and history of the different buildings inevitably affect the achieved results.
The study indicates that remote energy management offers an effective means to reduce the energy consumption and costs, and ultimately climate impacts derived from buildings.
The study adds to the knowledge of facilities management in context to energy management and environmental performance of buildings.
