Energy Management


The energy management standards EN 16001 and ISO 50001 are to help to increase energy efficiency, relieve the environment and reduce energy costs.

Motivation and benefits

The purpose of the energy specific standards EN 16001 and ISO 50001 consists in establishing systems and processes necessary to improve the energy related performance. Use of the standards is to help energy management to systematically contribute to reducing energy consumption, energy costs, greenhouse gas emissions or other environmental impacts. The systematic approach can be found in the organization’s energy management. Based on energy policy and the definition of the strategic and operational goals, action plans will be planned, implemented and assessed.

Austrian Energy Agency estimates the average energy saving potentials to be between 10 and 20 per cent. The standards can be integrated in existing management systems acc. to ISO 9001 and ISO 14001.

Target group

Basically energy management can be conducted by companies and organizations independently from the size or sector. For energy intensive companies, in particular the standard offers comprehensive systematic requirements and guides for successful implementation. As for small and medium sized enterprises, the standards initiate them in environmental management with the focus on the partial area of energy. As for companies with an existing environmental management system, the standards can contribute to focusing on the environmental factor of energy even more.


Examples of items covered by the term of energy include electricity, fuels, steam and vapour, heat, compressed air and renewable energies. The term of use of energy is understood very comprehensively, e.g. lighting, ventilation, heating, cooling, process heat, transport, processes and production lines.

EN 16001 strongly follows the structure of ISO 14001. In contrast to EN 16001. ISO 50001 includes the following items:

  •   Energy related assessment
  •   Energy related starting point
  •   Energy performance indicators
  •   Purchasing of energy services, products, facilities and energy.

The requirements are basically broken down into:

  •   Management Responsibility
  •   Energy Policy
  •   Legal Compliance
  •   Energy planning
  •   Energy related assessment
  •   Energy indicators
  •   Strategic and operational goals
  •   Awareness and training
  •   Purchasing
  •   Documentation
  •   Communication
  •   Conducting a management review

The organization must establish and document the scope and balancing limits of its energy management system. Top management must nominate a Management Representative.

Energy related assessment serves to analyze use of energy, determine the sources of energy, and assess energy consumption in the past and present and estimate the future needs. In this respect, the areas with the most important energy consumption will be identified. Energy policy includes commitment to continual improvement of energy specific performance. For measuring and monitoring energy related performance, adequate energy performance indicators will be established.
