ISO 50001:2011

International standard ISO 50001:2011

The worldwide standard for the creation of systematic energy management was published in 2011 by the ISO. It replaces the European standard EN 16001 and is, in contrast to this, recognized worldwide. The ISO 50001:2011 standard covers the complete production chain and brings transparency to energy consumption.

ISO 50001 Standard for Energy Management Systems

The standard creates outline conditions that make it possible to control energy consumption purposefully and improve energy efficiency. It defines requirements for the introduction, maintenance and improvement of an energy management system. For implementation of the standard, an energy planning process must be carried out and documented. The process must cover all activities that affect energy-related performance.

The following are some of the important points:

  • Energy-efficient purchasing of products and services must already be stressed in the definition of energy policy.
  • An operative energy manager must be nominated from top management.
  • An initial energy baseline must be created (an energy data period for energy consumption) and energy performance indicators must be created.
  • The processes for the maintenance and energy-efficient design of production processes and buildings must be defined.

The introduction of the standard is voluntary and there is in principle no legal requirement for certification. However national and European laws and requirements must be noted. However, the introduction of the ISO 50001 standard is recommended for all companies that need energy to fulfill their tasks.

Advantages of the implementation of ISO 50001

The introduction of the standard in the company has economic and ecological effects.

  • Economic: The introduction of an EMS in accordance with ISO 50001 improves energy efficiency, reduces energy costs and thus increases competitiveness. In addition, fluctuations in the price of energy have less effect if consumption is reduced.
  • Ecological: ISO 50001 was originally initiated in order to reduce environmental damage. It helps to lower the emission of environmentally harmful substances and to reduce the exploitation of natural resources.

ISO 50001:2011 is compatible with other environmental and quality standards such as EN 16001 or ISO 14001. A difference: Whilst ISO 50001 only relates to energy performance, ISO 14001 targets the overall environmental performance, i.e. it also includes waste, water and so forth. If other standards have already been implemented, the work involved in integrating ISO 50001 is reduced considerably.
