And this week, it is the lawyer Gwenaëlle Le Jeune who enlightens us on the Energy performance diagnosis, the famous DPE.

In place since 2006, it enables the measurement of energy consumption for the rental or sale of a home via a rating ranging from A to G. One way in particular to identify “thermal strainers”.

Problem: diagnoses have led to overestimating the faults of certain dwellings built before 1975. An adjustment of this new DPE is expected for November 1, but the questions remain numerous.
