What is an ISO 50001 - EnMS


ISO 50001 = A certified energy management system (EnMS).

What you will need:


  1. An energy policy (continuously reviewed and updated);
  2. Meet all applicable energy legal requirements;
  3. Plan - Do - Check - Act system for managing energy use;
  4. Monitor and improve energy efficiency;
  5. Senior management buy-in and review;
  6. Documentation of all of the above.

ISO 50001:2011 requires organisations to:

  • Continually improve energy performance, including energy efficiency, energy use and consumption;
  • Define their energy policy and document an energy planning process;
  • Review energy use, consumption and efficiency at defined intervals;
  • Document the methodology and criteria used to develop the Energy Review considering facilities, equipment, systems or processes;
  • Establish an energy baseline and identify EnPIs (Energy Performance Indicators) appropriate for monitoring and measuring it’s energy performance;
  • Establish, implement and maintain documented Energy Objectives and Targets.
An effective energy management system based on ISO 50001 provides an organisation's top management with a roadmap which allows them to:
  • Minimise energy usage.
  • More effectively meet legislative and regulatory requirements and therefore be viewed more favourably by regulators.
  • Provide an opportunity to systematically plan, control and monitor operational activities and processes that may impact on energy usage.
  • Incorporate energy efficiency in the planning of all new investments.
