What is … EN 16247?

The European standard EN 16247 regulates the field of energy management and defines the requirements of energy audits. But how is it structured and what are its advantages? EnExpert explains!

In general, an energy audit aims to systematically examine the energy use and consumption of companies, organizations, facilities and buildings in order to improve energy efficiency and reduce energy consumption. The EN 16247 standard specifies the requirements that an energy audit must meet in order to be considered of good quality. This is intended to create clarity and transparency in the market for energy audit services. 

Overall, the EN consists of 5 parts, with the first part being of importance for energy audits. 

  • Part 1: General requirements
  • Part 2: Buildings
  • Part 3: Processes
  • Part 4: Transport
  • Part 5: Competence of energy auditors  

EN 16247-1 General requirements 

The General Requirements define the scope, normative references, and terms. In addition, the quality requirements are set out. These state that an energy audit must be qualified, transparent, and disclose possible conflicts of interest. Furthermore, an energy audit must be appropriate, complete and representative, include analyses of energy savings, and the results must be verifiable. 

In addition, the first part also defines all the elements of the energy audit process. Here, the objectives, requirements, scope and limits, period of implementation and requirements of the data must be defined in advance. 

EN 16247-2 Buildings 

The second part of EN 16247 describes the specific requirements, methods and results of an energy audit for buildings. These are in addition to the general requirements.

EN 16247-3 Processes 

The third part of EN 16247 describes the specific requirements, methods and results of an energy audit for industrial processes. These must be applied to all sites where energy consumption is caused.

The fourth part covers the additional requirements for energy audits in the transport sector. 

EN 16247-5 Competent of energy auditors  

The last part of EN 16247 includes qualification programs for energy auditors for the national level.
