The DPE must be issued with the rental contract and at the time of renewal of the lease. In addition, according to a ministerial response, the tenant in place can request a new DPE from his lessor at the time of the tacit renewal of the lease, in order to verify that the accommodation respects energy decency.

The DPE (energy performance diagnosis) has included the following information since July 1, 2021:

• The relevant characteristics of the building and a description of its equipment for heating, hot water production, cooling, ventilation;
• The annual quantity of energy consumed or estimated by category of equipment as well as an assessment of the annual expenditure resulting from this consumption;
• The classification of the accommodation in application of a reference scale, taking into account the climatic zone and the altitude, established according to the quantity of greenhouse gas (GHG) emissions, related to the surface of the building;
• Recommendations aimed at improving energy performance without increasing the quantity of GHG emissions, accompanied by an assessment of their cost and effectiveness
• Where applicable, the latest boiler inspection report;
• Elements of assessment on the capacity of the accommodation to ensure thermal comfort in the summer period.

It is established by a professional diagnostician, and attached to the diagnosis file technique during the compromise (or the promise), then the authentic deed of sale.

All DPEs made on or after July 1, 2021 are valid for 10 years.
For DPEs made between January 1, 2013 and December 31, 2017, they are valid until December 31. Those made between January 1, 2018 and June 30, 2021, are valid until December 31, 2024.

Ads must refer to the energy class of the property for sale (or to rent) as well as the climate class.
Note: From January 1, 2022, advertisements for sale and rental must indicate the amount of theoretical annual energy expenditure for standard use. The words “dwelling with excessive energy consumption” should also appear where applicable, followed by the words “class F” or “class G”.

The DPE is established on any closed and covered building, which has a heating system (other than an open fireplace) or a air conditioning.

Certain properties are exempt from the DPE:

• Temporary constructions intended for a period of use of 2 years at most,
• Independent buildings whose the floor area is less than 50 m2,
• Buildings or parts of buildings for agricultural, artisanal or industrial use, not used for habitation, in which the system for heating or cooling or producing hot water for human occupancy produces a small amount of energy compared to that needed for economic activities,
• Buildings used as places of worship,
• Historic monuments classified or listed in the inventory,
• Properties that are intended to be used less than four months per year.

When the property includes a collective device for heating, cooling or hot water production, the < a href="/immo,lexique.htm#dpe">DPE is provided by the device owner, or by the co-ownership trustee. It is drawn up at the expense of the person requesting the diagnosis.

A to know: As of January 1, 2023, accommodation with a consumption greater than 450KWh/m².year (label G) will be considered as indecent and cannot no longer to be rented.

As of August 25, 2022, it will no longer be possible to revise or increase the rents for properties classified F or G, rented as the tenant's main residence. However, this only concerns leases that have been concluded, renewed or tacitly renewed from this date.
