Energy audit
Systematic analysis of the energy use of a site or organisation, in line with standard EN 16247, leading to a costed action plan. Since the French DDADUE law of 30 April 2025 transposing Directive (EU) 2023/1791, the obligation depends on consumption: an audit every four years above 2.75 GWh/year, and an ISO 50001 energy management system above 23.6 GWh/year.
