Energy Performance Diagnosis

Mandatory diagnosis before any sale or rental.

Why do we need to carry out an DPE?

What is the purpose of the DPE?

With global warming, the energy performance diagnosis (ECD) has gone from being a mandatory real estate diagnosis before selling or renting to a full-fledged expertise that is useful to carry out even in the absence of a transaction.

Indeed, the DPE evaluates the energy consumption of a property, its environmental impact in terms of greenhouse gas emissions and allows to know the corrective actions to be taken to reduce both energy bills and pollution caused by consumption.


When should the DPE be carried out?

 It is imperative that the DPE be carried out before the advertisement for the sale or rental of a property is published. Indeed, the publication of the advertisement on the Internet or in the window of an agency requires the property’s energy rating generated by the DPE (letter from A to G) to appear. The energy performance diagnosis, which is valid for ten years, reviews all the parts and equipment of the dwelling that are directly related to its energy efficiency.

Thanks to a software and a regulated calculation method, the DPE leads to recommendations for energy saving works in adequacy with the situation of the housing and intended to improve its energy classification.

Modification Of The DPE In 2021

As of July 1, 2021, the method called “on invoice” which currently concerns housing whose building permit was filed before January 1, 1949 and housing with collective heating will disappear. The new DPE will be based solely on the characteristics of the property such as the quality of the building, the insulation, the type of windows and heating system…..

This new method will take into account new parameters whose objective will be to give a more reliable assessment of the energy performance of the building such as energy consumption in lighting, ventilation and cooling systems. The new DPE will also include additional information such as summer comfort and heat loss. The objective is to prohibit the rental of housing called “thermal flats” in 2028 (housing currently classified F and G).
