The Diagnostic of Energy Performance (DPE)

It is a mandatory document when selling or renting a property in France. It aims to inform future occupants about the energy performance of the property in question, by providing data on its energy consumption and greenhouse gas emissions.

Since July 1, 2021, new regulations concerning the DPE have come into force. These changes have been made to improve the accuracy and reliability of the diagnosis, taking into account the latest technological and normative developments in construction and energy efficiency.

First of all, the rating criteria of the DPE have been modified, with the introduction of two new classes, A and B, to reflect energy performances superior to the previous highest classes (A+, A++ and A+++). The G class, corresponding to the worst performing homes, has been extended to include homes with energy consumption above 450 kWh/m²/year.

Secondly, the calculation methods of the DPE have also been modified to take into account the latest standards in construction and equipment. Energy consumption data is now based on actual energy consumption records, rather than estimates. Greenhouse gas emissions data are also included in the report, to allow for a more accurate assessment of the environmental impact of the home.

Finally, diagnosticians must now undergo specific training to carry out the DPE, and must be certified by an independent body to ensure their competence and impartiality.

These new regulations aim to improve the transparency and reliability of the DPE, by providing occupants with more accurate and reliable information on the energy performance of their home. This may also encourage homeowners to undertake energy renovation work to improve the performance of their homes, which can help reduce greenhouse gas emissions and improve the quality of life of occupants.
