DIN EN 16247-1 and ISO 50001 – commonalities and differences

EnMS according to ISO 50001 energy audit according to EN 16247
Target group Suitable for all organizations and company sizes. Suitable for all organizations as an introduction.

Content Requirements for the introduction, implementation, maintenance and improvement of an EnMS. Guide to conducting an energy assessment starting with the contractual agreement with the energy auditor on the conduct and scope of reporting.
Management system Integrated management system based on the continuous improvement process known as the PDCA cycle. No management system with a continuous improvement process.
Energetic evaluation The energetic evaluation is an essential part of ISO 50001.

ISO 50001 specifies further requirements that are taken into account in all processes of the organization.

Systematic investigation and analysis of the energy input and the energy consumption and determination of the saving potentials
(= energetic evaluation).
Scope and application area of the examination Organization defines the scope and limits of the EnMS.

All types of energy and energy consumers, all company processes.

The representativeness of the energy audit is assumed in any case if at least 90 % of the total energy consumption of a company is covered by the energy audit on the basis of an overall recording of energy consumption.
Prospects of success Commitment of top management, involvement of all employees, holistic management system. Depending on the scope of the energy audit, depending on the individual commitment of the operational managers.
