New DPE - July 2021

The essential points


The DPE (Diagnostic for Performance of Energy) has been improved. It is now more reliable, more readable, and takes into account climate issues. Released on July 1, 2021, this new energy performance diagnostic is valid for ten years.

Buyers and lessees of a home after July 1, 2021, will therefore receive this new DPE. 
For DPEs carried out according to the old system between January 1, 2013, and July 1, 2021, a derogatory period has been set up. It is defined as follows: 

  • DPEs dated from January 1, 2013, to December 31, 2017, remain valid until December 31, 2022;
  • DPEs dated from January 1, 2018, to June 30, 2021, are valid until December 31, 2024.

As of January 1, 2025, only new DPEs will be valid.

Here are the main differences between the old and the new DPE version:


New Energy performance diagnosis: More precise


For the previous energy performance diagnosis, the method consisted of auditing the physical characteristics of the housing (buildings, heating, insulation, etc.). A score from A to F took into account the energy consumption of the dwelling. Greenhouse gas emissions were indicated but not taken into account in the calculation.

From now on, the note of the new DPE of July 2021 considers the consumption of primary energy (energy label) and greenhouse gas emissions (climate label).

The previous DPE based on the energy bills of the previous occupants of the dwelling was unreliable. Therefore, the new method takes the average annual expenditure of 5 energy usage in the home: heating, hot water, lighting, air conditioning, auxiliaries (VMC).


New Energy performance diagnosis: More informative


Previously, the DPE did not contain detailed information on the energy performance of all elements of a dwelling. From now on, the DPE indicates the positive and negative points of the home in terms of energy consumption: heat loss, insulation performance, ventilation system, and renewable energy production systems (if any). It must also mention the work to be carried out to improve the home's energy performance, specifying whether this work is a priority. 


New Energy performance diagnosis: Clearer


The cover page of the DPE is simplified. It now summarizes the essential information (energy label, climate label, and estimate of annual energy expenditure). In addition, the inside of the document features colors to make it easier to read.

New Energy performance diagnosis: Legal scope


This new diagnosis becomes opposable, meaning it is possible to challenge it. In other words, buyer and tenant can turn against seller or lessor in case of errors in the energy label.

For example: if an owner sells his property labeled class E when it is a class F or G, it may incur his liability. He will have to carry out energy renovation work. The same sanction applies to landlords of rental accommodations.

Nota Bene: As of January 1, 2021, it is no longer possible to increase the rent for accommodation known as "thermal strainers." 

A future ban on letting classified F or G housing is in progress (in 2025 for G housing, in 2028 for F housing).


The objective of these new regulations


The new diagnosis's objective is to inform the purchaser or the tenant about the energy performance of their future home by calculating the consumption of goods and making owners aware of the importance of energy renovation to preserve our planet. 


How does the new July 2021 DPE label look?


The double threshold DPE label provides information on energy consumption and carbon emissions. Therefore, the lower of the two scores is retained as the overall label of the accommodation.  

The "Energy" label (calculation of class A, B, etc.) displays primary energy consumption* and greenhouse gas emissions**. 

Warning:  Goods of class F or more will be rated "energy strainer."

As a reminder, the DPE, like the other elements of the technical diagnostics file, is mandatory in the event of rental and sale. There is one exception, however, for rentals of a duration period under four months. 

* Primary energy sources: crude oil, natural gas, solid fuels (coal, biomass), solar radiation, hydraulic energy, geothermal energy, and energy from nuclear fuels.

** Greenhouse Gases (GHGs): natural gases present in the earth's atmosphere trapping the sun's rays and stabilizing the temperature on the planet's surface.
