Effective implementation of ISO 50001: A case study on energy management for heating load reduction for a social building stock in Northern Italy

Organisations responsible for managing large stocks of residential social buildings spend significant re- sources on the energy usage for buildings and maintenance activities. The implementation of an energy management system compliant with ISO 50 0 01 can yield more effective energy retrofit actions for buildings by improving the energy consumption and environmental performance of buildings through effective economic investment strategies. This paper describes an organisational methodology that complies with ISO 50 0 01, applied for the first time to an Italian public body that manages a large building stock of social housing. In particular, this study examines the aspects concerning energy analysis of the stock and the definition of energy retrofit interventions towards heating load reduction based on consumption monitoring. The obtained results confirm the effectiveness of ISO 50 0 01 as an organisational tool for energy management within a systematic approach
