ISO 50001 2011 Edition tackles the problem of Energy management systems – Requirements with guidance for use

The new ISO 50001:2011 specifies requirements for establishing, implementing, maintaining and improving an energy management system.  The new document, titled “Energy management systems — Requirements with guidance for use,” is expected to be adopted by the European Union as EN-ISO-50001 and will replace EN-16001.

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.  And Annex A provides informative guidance on its use.

The ISO standard applies to all variables affecting energy performance that can be monitored and influenced by the organization. However, it does not prescribe specific performance criteria with respect to energy.

ISO 50001 has been designed to be used independently, but it can be aligned or integrated with other management systems.

It is applicable to any organization wishing to ensure that it conforms to its stated energy policy and wishing to demonstrate this to others, such conformity being confirmed either by means of self-evaluation and self-declaration of conformity, or by certification of the energy management system by an external organization.

Energy management can reduce energy consumption, leading to:

  • Reduced energy costs
  • Reduced carbon emissions
  • A more secure supply of energy
  • Improved reputation when implemented with certification
  • ISO 50001 enables organizations to take a systematic approach to energy management. It’s goal is to help companies achieve continual improvement of energy performance, energy efficiency and energy conservation.

    Who should buy this standard?

  • Anyone who wants to reduce their energy costs, reduce carbon emissions or improve their organization’s reputation
  • Those who want a better understanding of international best practice energy management
  • Users of ISO 14001 who want to further develop their management of energy and increase their performance and savings
  • Those responsible for planning and implementing an energy management system
