Recommendation ITU-T L.1303 describes the functional requirements and framework of an energy-saving management system for green data centres. Functional requirements of energy-saving management include requirements for measuring energy consumption and environmental conditions data, collecting and storing data, reporting data and conducting energy-saving. The energy-saving management system consists of the following functional blocks: data collecting block; data storing block; data process and analysis block; external system interfacing block; user interface block; control block. The operational flow of the energy-saving management system is also included.
