New energy performance diagnosis: panic in the real estate sector

The new energy performance diagnosis (DPE), in force since 1is July, reveals some nasty surprises to the owners of the many listed energy-intensive homes. The DPE, established by an approved professional by theoretical calculation based on the technical characteristics of the building, and no longer on the energy bills, scores the goods from A, the best score, to G, the worst, according to their energetic performance. It must be annexed to any contract of sale or rental, with, henceforth, serious legal consequences.

Indeed, under the climate law of August 22, 2021, from 1is January 2025, the 600,000 G-rated dwellings will be considered indecent and therefore prohibited for rental. The same fate will be reserved, in 2028, for 1.2 million homes classified F, and, in 2034, 2.6 million homes classified E. But from August 25, 2022, rents for homes classified F and G will not can no longer be increased, neither by applying an index during the contract, nor during a lease renewal or relocation.

Sales are affected. The site is seeing an influx of ads for energy-inefficient housing. Thierry Delesalle, a Parisian notary, saw a sale fail because of a score lower than that announced by the saleswoman … However, the first new version diagnoses, carried out for a few months, have shifted into the infamous categories of many more housing than foreseen.

Work for nothing

Marcel Crasnier, owner of around thirty homes in the agglomeration of Angers, is not fearing. He had an entire building renovated in Rochefort-sur-Loire (Maine-et-Loire), and signed an agreement with the National Agency for the Improvement of Housing (ANAH) to fit out five apartments with social vocation (opening therefore entitled to a reduction of 85% on property income, according to the tax system known as « Cosse »), rented per month between 7 euros and 8 euros per square meter.

« Doing social does not scare me, for example, I rented 425 euros per month a 70 m2 to a young couple, or to students, retirees. But while I had, before the work, a prospect of label D established by a thermal design office, the DPE after work leads, for three of the five dwellings, to an E classification, which not only compromises the payment of the subsidy of 150,000 euros from the ANAH but also, in the long term, the possibility of renting these accommodations ”, he fears.

Mr. Crasnier has nevertheless invested 450,000 euros in insulation, double glazing and the installation of state-of-the-art radiant electric heaters. « These operations are complex, they require two to three years of preparation and months of construction, so we must not change the rules suddenly », protests-t-il.
