Developing of an Offline Monitoring Method for the Energy Demand of a Healthcare Facility in Italy

Hospitals are among the most energy-intensive buildings in the service industry. Developing energy management strategies could lead to important energy savings, and it must pass through detailed analyses of each specific activity's energy requirement. The present study aims to find a healthcare facility's main energy drivers and develop an offline monitoring method applicable to future healthcare energy requirements. A Multiple Linear Regression model has been realised to define the standard energy consumption based on the year 2019, allowing a Cumulative Sum of differences control chart including the 2020 energy consumption data. The proposed method allows finding variations between actual and standard building energy demands, a useful tool to monitor the effectiveness of energy system control strategies.
