The collective EPD shall include the following elements:

• The amount of energy actually consumed or estimated, expressed as primary and final energy, and the greenhouse gas emissions induced, for a standardized use of the building or part of a building
• A baseline classification to compare and evaluate the energy performance of the building or part of a building and its greenhouse gas emissions performance
• Information on aeration or ventilation conditions

It is accompanied by recommendations to improve performance and the amount of theoretical expenditure.

Since 1^er january 2024, single-family buildings and condominiums of more than 200 lots of which the building permit was filed before 1^er January 2013 must carry out a collective EPD.

The collective EPD will also become mandatory:

• From 1^er january 2025 for condominiums containing between 50 and 200 lots
• From 1^er january 2026 for co-properties of up to 50 lots.

The condominium trustee must subscribe to the agenda of the general meeting of the co-owners the decision to implement the collective EPD.

This decision may be voted on by the majority of votes cast by the co-owners present and represented (majority Article 24).

The simple majority (said majority of article 24) corresponds to a majority of the votes cast by the co-owners present or represented and those who voted by mail. Abstentions are therefore not taken into account.

The collective EPD must be established by a diagnoser. The trader must meet certain conditions:

• Independence and impartiality : it must not have any link liable to impair its impartiality and independence, neither with the owner or his representative nor with the liquidator, nor with a company capable of carrying out work on the works, installations or equipment for which they are required to draw up the collective EPD
• Skills, organization and resources : he must have a certificate of competence issued by a certifying body approved by COFRAC, which makes it possible to ensure that he meets the requirements of a given reference system of competence
• Insurance : he must take out professional liability insurance

To find a diagnoser that meets these conditions, you can consult the Directory of Certified Real Estate Diagnostics:

Find a Certified Real Estate Diagnoser

The diagnoser can establish the collective EPD by visiting all the dwellings in the building or on the basis of visiting a sample of dwellings.

The description of the envelope and equipment at building level is obtained by extrapolation from the data collected in the sample.

The condominium trustee shall provide the diagnoser with:

• If the building has a collective heating, cooling, domestic hot water or ventilation installation: description of these collective facilities, their auxiliaries and their management and the arrangements for apportioning costs related to the energy consumption of such equipment;
• For other collective devices, such as the outer envelope, the roof, floors, ceilings and internal partitions opening onto unheated premises, any document at its disposal providing information on the relevant characteristics of such devices affecting energy consumption, in particular the dates and descriptions of the thermal insulation work carried out, the invoices relating thereto and the technical diagnoses made.

In the case of a collective heating and/or domestic hot water production installation, if no information is provided on the collective equipment, a default calculation must be made, which penalizes the result of the collective EDP.

The diagnoser must transmit the results of the collective EPD to the Ecological Transition Agency (Ademe):

Transmission of energy performance diagnosis (EPD) to Ademe

The diagnoser may be fined €1,500 if it does not forward these results to the Ademe.

Collective EPD needs to be renewed or updated every 10 years, except where an EPD is conducted after 1^er july 2021 establishes that the building belongs to energy class A, B or C.
