The energy performance diagnostics (DPE) carried out on buildings prior to 1975 are now reliable.
The bugs concerning them have been corrected, according to the Minister of Housing Emmanuelle Wargon, this Thursday, December 2.
This category of goods will no longer be unfairly considered as energy sieves (DPE E, F or G) in the absence of facade insulation or information on their thermal equipment.
On September 24, the ministry suspended the realization of these DPEs for all dwellings built before 1975 after being alerted to malfunctions.
Due to various "anomalies" in the calculation methods, a large majority of old dwellings suffered from a poor energy class.
The 160,000 DPE carried out since the implementation of the corrective at the beginning of November no longer present "anomalies", the minister indicated in a press release after a meeting organized with all the professionals in the sector.
"The representatives of the diagnosticians confirmed that this corresponded to their return from the field", specifies the document.
223,000 DPE concerned
If you had an energy diagnosis carried out on your property built before 1975 between July 1 and the end of September, that is to say with the old calculation method, and it came out classified D, E, F and G, you are entitled to request a reprint of your DPE free of charge.
The diagnosticians have undertaken to reissue them, free of charge, to all those who request them by February 28.
In return, professionals will be compensated up to 60 euros for each reissued DPE, whether or not they require travel.
According to the ministry, 223,000 DPE are likely to be reissued.
"The corrections made to the software are effective, the goods have on average gone up one category: goods classified G become F and F are noted E, underlines Danielle Dubrac, president of the Union of real estate unions ( United) which represents all trades in the sector (real estate agents, agents, trustees, experts, etc.).
Of the 160,000 DPE carried out since November 1, 21% have lost their energy strainer label granted by the old method of calculation set up between July and October ”.
