ISO 50001 is a voluntary international standard developed by ISO, the International Organization for Standardization and it contains requirements for energy management systems (EnMS). ISO 50001 may help organizations, large and small, in managing and improving their energy consumption and efficiency. Many experts believe that behavioral-driven approaches to energy use can, in many cases, lead up to 50% of energy use reduction, without compromising production output. The purpose of ISO 50001 is to enable organizations to establish systems and processes necessary to continually improve it’s energy performance including energy efficiency, use and consumption. ISO 50001 is intended to foster reductions in energy consumption, greenhouse gas emissions and other related environmental impacts, through systematic management of energy. As in all Management System Standards, successful implementation depends on commitment from all levels and functions of the organization but, and especially, from top management.
ISO 50001 specifies requirements of an energy management system (EnMS) for an organization to develop and implement an energy policy, establish objectives, targets, and action plans, which take into account legal requirements and information related to significant energy uses (SEU). An Energy Management System enables an organization to achieve its policy commitments, take action as needed to improve its energy performance and demonstrate the conformity of the system to the requirements of standards such as ISO 50001 and/or the European Norm EN 160001. Implementation of ISO 50001 must be tailored to fit the organization implementing it, including the complexity of the system, degree of documentation, and resources.
Using energy efficiently helps organizations save money as well as helping to conserve resources and tackle climate change. ISO 50001 supports organizations in all sectors to use energy more efficiently, through the development of an energy management system
ISO 50001 is based on the management system model of continual improvement also used for other well-known standards such as ISO 9001 or ISO 14001. This makes it easier for organizations to integrate energy management into their overall efforts to improve quality and environmental management.
ISO 50001 provides a framework of requirements for organizations to:
· Develop a policy for more efficient use of energy
· Fix targets and objectives to meet the policy
· Use data to better understand and make decisions about energy use
· Measure the results
· Review how well the policy works, and
· Continually improve energy management.
ISO 50001:2011 specifies 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 use and consumption.
ISO 50001:2011 specifies requirements applicable to energy use and consumption, including measurement, documentation and reporting, design and procurement practices for equipment, systems, processes and personnel that contribute to energy performance.
ISO 50001:2011 applies to all variables affecting energy performance that can be monitored and influenced by the organization. ISO 50001:2011 does not prescribe specific performance criteria with respect to energy.
ISO 50001:2011 has been designed to be used independently, but it can be aligned or integrated with other management systems.
