Management system certification / Voluntary assessment

Basis for Certification (certification standard):

International standard ISO 50001 (requirements for energy management systems)

Standard owner:

ISO International Organization for Standardization


What does the standard ISO 50001 cover?

The ISO 50001 standard defines the requirements for a certifiable energy management system (EnMS) of an organisation. These requirements include, but are not limited to:

  • Development of a corporate policy for more efficient energy use
  • Development and implementation of energy reviews to identify opportunities of improvement in energy performance
  • Establishment of strategic and operational targets and objectives for the implementation of energy policy
  • Control and monitoring of operational processes and maintenance activities associated with significant energy use (SEU)
  • Monitoring, measurement and analysis of the main characteristics of energy performance
    Evaluation of the suitability, appropriateness and effectiveness of the energy management system.
  • Continuous improvement of the organisation's energy performance.

  • What does “certification” and/or the issue of a certification mark for ISO 50001 by TÜV SÜD Management Service GmbH mean?
    • The customer has submitted to voluntary assessment (audit) according to defined criteria (certification standard).
    • A certificate and/or the authorisation to use a certification mark is only issued if the assessment (audit) does not reveal any major nonconformities with the requirements of the certification standard.
    • The certificates and/or certification marks are valid for a restricted period of time. Interested parties can check the validity of individual certificates in the certificate database of TÜV SÜD Management Service GmbH.
    • To maintain certificate validity, the certificate holder must annually complete an announced audit with a positive result.
    • Unannounced audits are possible in specific cases.
  • How do we audit?

    Independent and qualified experts (auditors) apply the following auditing techniques:

    • Document review:
      Evaluation of the organisation’s requirements and/or documentation to ensure the systematic control of all processes relevant for energy management system

    • On-site-audit:
      Verification, in the form of interviews and on-site inspection at the customer's premises, that the above requirements are effectively implemented in practice.
      Random on-site checks of energy-relevant plants / facilities as well as processes and local conditions
      based on records, such as available measurement results, energy consumption and energy efficiency performance indicators, minutes of meetings, planned and implemented measures to improve energy efficiency
  • What is beyond the scope of certification according to ISO 50001?
    • Certification according to ISO 50001 does not constitute product certification. Certification thus does not provide any direct statements on the energy efficiency of a product or service of the certified customer.
    • Certification according to ISO 50001 does not mean that the company manufactures products or provides services of higher energy efficiency.
