Effects of the new standard
The German Accreditation Body (DAkkS) has decided that as from 14 October 2017, all certification bodies accredited for ISO 50001 must perform certifications and recertifications according to the new ISO 50003 accreditation standard. The ISO 50001 certification standard will remain in its present form, and the current TN CERT accreditation according to ISO 50001 will be transferred to the new ISO 50003. The changeover will also have an impact on companies.
It means that companies that have already put in place a certified EnMS or that wish to achieve certification in future have to demonstrate continual improvement of their energy performance in more detail. Under the new regime, quantified evidence will have to be provided in the form of measurable results which are compared with the energy baseline or the previous measurement period. There will therefore be greater emphasis on measurement and on concrete evidence of improvement in energy efficiency and also energy performance indicators (EnPI).
Help and practical tips
Additional guidance can be found in the following published standards:
- ISO 50004 (EnMS – Energy management Systems - Guidance for the implementation, maintenance and improvement of an energy management system)
- ISO 50006 (EnMS – Energy management Systems - Measuring energy performance using energy baselines (EnB) and energy performance indicators (EnPI) - General principles and guidance
- ISO 50015 (EnMS – Measurement and verification of energy performance of organizations - General principles and guidance)
Other important changes
Other important changes as a result of the changeover:
- There will be a new basis of calculation for audit time. In future, the calculation will take into account the number of energy sources, the energy consumption, the number of significant energy uses and the number of employees who have a material impact on the EnMS and/or on energy performance, and whose actions play a role in fulfilling the requirements of the EnMS. Overall, this can lead to changes in relation to audit times and therefore also to different costs for companies.
- Industry-specific assessment of auditor competence (eight technical areas replace the previous two sectors). This may lead to changes in auditors for some companies.
Aspects for companies
The changeover means that in future, companies will need to focus more strongly on measuring and demonstrating improvement in energy performance. The following aspects are particularly important:
- Determination of appropriate / relevant energy performance indicators (EnPI)
- Ensuring that the energy baseline (EnB) is meaningful and appropriate
- Type, place and time of the measurements
- Type of documentation for measurements and their results
