Real estate and diagnostics professionals call for rapid improvement in new DPE

During a meeting with the DHUP on Thursday, September 16, FIDI is pleased to have been heard on the difficulties of setting up the new DPE and remains reasonably optimistic about taking into account its proposals for improvements. within a few weeks.

The Union of Real Estate Syndicates (UNIS), and the Interprofessional Federation of Real Estate Diagnosis (FIDI), intend to combine their skills and their strengths to decipher "THE NEW DPE", made reliable, enforceable and aimed at the eradication of strainers energies and limiting Greenhouse Gas (GHG) emissions.

The version currently in force (DPE version v.3) has revealed its limitations:

Indeed, on the strength of the numerous feedbacks from their members since July 1, FIDI and UNIS have drawn up identical reports of dissatisfaction. FIDI was able to enumerate and concretely explain the elements leading to very significant differences in the results of the DPE V3 compared to the reality on the ground and to the V2 of the DPE. These elements were the subject of a recent exchange with the Department of Housing, Town Planning and Landscapes, Ministry of Ecological and Inclusive Transition (DHUP).

A first analysis identifies two probable causes:

• The calculation of the cost of consumption, by installments, does not correspond to reality. In electricity, for a given number of kWh, the error is more than 30% compared to the real cost of the kWh!
• Certain parameters of the calculation engine related to the occupants' lifestyle have been significantly modified compared to the previous version. They may not correspond to the reality on the ground. These new parameters substantially degrade the consumption estimate but also the DPE score.

In addition, thermal engineers have noted concrete problems, which significantly downgrade the rating (as a reminder, from A to G, G being the most unfavorable):

• In addition to the changes to the ventilation by opening a window, it seems that there is a problem with the calculation of the infiltration flow rates which gives losses almost 10 times greater than the previous version.
• The calculation of the consumption of the circulation auxiliaries for an apartment in an apartment building seems inconsistent (the pumps consume almost as much as the total DHW!).
• By making a comparison between the V2 and the V3 with the same losses (identical envelope), we obtain much more consumption.

Another point was raised, which does not play on the note:

• Estimate of summer comfort: if the toilet window does not have a shutter, the estimate is degraded regardless of the other parameters.

If the public authorities do not wish to go back on certain choices, it is imperative that they clearly explain to real estate professionals the parameters adopted and the reasons for their choices.

Other difficulties were also raised during this exchange and continue to be discussed during the weekly working groups in which FIDI has participated for almost two years, and intensively since early May 2021.

The findings of the diagnosticians agree with those of the professionals of the University who thus underline:

• The incomprehension of customers who see their property downgraded without having understood how their property is detrimental to energy saving and GHG reduction objectives;
• Difficulties in accessing the technical rooms of the building in the allotted time;
• The difficulty of having the technical references of the insulators used more than 10 years ago;
• The classification as “fuel” boilers of “gas” boilers whose characteristics (type, power, etc.) have not been indicated, automatically resulting in penalizing downgrading.
• Differences between the ratios of living space of apartments and the condominium fees;
• The extension of time to market (rental) pending DPE.

For Danielle Dubrac, president of the Uni: “The Unis had advised condominiums and lessors to establish a new DPE; for everyone, the landing is therefore very hard. In this context, the question of opposability weighs too heavily. The public authorities have moved too quickly. The impact on the park is significant. How to calmly consider the calendar of the Climate Law (ban on renting DPE-G from 2023)? We hope for a quick remedy, being resolutely committed to energy renovation and to supporting our customers ”.

For Lionel Janot, president of the FIDI and Stéphane Prouzeau, vice-president, the exchanges with the DHUP were very productive and effective. To date, they have no doubt that adjustments will be taken into account quickly to improve the reliability of the DPE V3s and make them really efficient.

While waiting for the meeting with the Minister in charge of Housing, Ms. Emmanuelle WARGON, on October 4, where the various issues concerning the DPE, but also the energy audit, will certainly be discussed, in the context of the fluidity of the energy market. real estate, the diagnosticians are of course continuing to carry out the DPEs.

Stéphane Prouzeau specifies: “For the moment, we must give the DHUP officials time to take into account the realities on the ground set out by us. We remain very attentive and open, but we will not fail to come forward with more insistence, if the ECD does not evolve quickly. "

For Danielle Dubrac, President of UNIS: “UNIS has worked with FIDI diagnosticians to better master this new tool, so that professionals can fully fulfill their duty to advise their clients. Working in the industry is an asset for everyone with the goal of renovation. "

And Lionel Janot, President of FIDI, to conclude: “UNIS and FIDI are working together to support, inform and explain to all real estate players the new DPE and its impact on tomorrow's daily life. The professions of FIDI and UNIS are essential in the life cycle of a property, which is why it is essential that our professions continue these exchanges and this collaboration in order to build close relationships in order to provide a maximum service and information.
