Energy management systems’ requirements with guidance for use is a specification created by the International Organisation for Standardisation (ISO) for an energy management system.
The standard specifies the requirements for establishing, implementing, maintaining and improving an energy management system, whose purpose is to enable an organisation to follow a systematic approach in achieving continual improvement of energy performance, including energy efficiency, energy security, energy use and consumption.
The standard aims to help organisations continually reduce their energy use, and therefore their energy costs and their greenhouse gas emissions.
ISO 50001 was released by ISO in June 2011 and is suitable for any organisation whatever its size, sector or geographical location.
The system is modelled after the ISO 9001 Quality Management System and the ISO 14001 Environmental Management System (EMS).
ISO 50001, therefore, has made a major leap forward in ‘raising the bar’ by requiring an organization to demonstrate that they have improved their energy performance. There are no quantitative targets specified – an organization chooses its own then creates an action plan to reach the targets. With this structured approach, an organization is more likely to see some tangible financial benefits.
