A Study on Energy Efficiency in Enterprises: Report on the qualification of energy auditors in all Member States

Share this Post:

This study, elaborated by DNV GL for the European Commission aims to support the Commission by providing an overview of current implementation practices, tool and instruments related to Article 8 of the Energy Efficiency Directive (EED) within the different Member States (MS). This report, specifically, addresses the establishment of national legislation requirements for energy auditors, and for supervision by national authorities, across the MS. This includes an identification of approaches used by MS to put in place accreditation schemes for energy auditors, to make sure that a sufficient number of reliable professionals are available. Best practices are also presented, especially with respect to opportunities for harmonisation of qualification requirements across borders.


For this purpose, the following research questions were used to identify structure and analyse the information available for each MS:


  • Energy auditor accreditation schemes
  • Energy auditor tools and training
  • Energy auditors’ register
  • Mutual recognition


Main conclusions


At the time of this report, 22 MS had implemented accreditation schemes and adopted Article 8 qualification criteria for energy auditors. Mandatory training requirements exist in 13 MS, whereas minimum education requirements based on certain degrees have been set up in 22 MS. Guidelines, templates and calculation tools have been developed by a number of MS in order to assure the quality of energy audits and assist auditors in meeting the requirements, as well as improving the process of identifying energy saving opportunities. In general, good initiatives are already implemented regarding the accreditation of energy auditors but it is quite surprising to see that some MS, such as the Netherlands and Poland, do not have any clear guidelines or requirements in place. The lack of clear requirements may complicate and delay the audit process and compromise the quality of the audit results.


It should be noted that substantial progress on the development of accreditation and certification schemes has been made in accordance with Article 16 and Article 17 of EED implementation by the MS.
