ISO 50001:2011 Energy management systems requirements with guidance for use is a specification created by the International Organization for Standardization (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 organization 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 organizations continually reduce their energy use, and therefore their energy costs and their greenhouse gas emissions. ISO 50001 Standard specifies requirements for an Energy Management System to enable organization to develop and implement a policy, controls for identified significant areas of energy consumption and energy reductions. It resets the best practices in energy management upon existing national standards and initiatives.
The main objective of the standard is to improve energy-related performance and energy efficiency continuously and to identify energy reduction opportunities. This systematic approach will help organizations to establish systems and processes. Consistent energy management helps organizations to realize untapped energy efficiency potential. They will benefit from cost savings and make a significant contribution to environmental and climate protection.
