DPE software, or how to find out the energy performance of a property in just one click

The energy performance of residential buildings is at the center of discussions for players in the sector. The reason? Public authorities are keen to facilitate the energy transition of France's housing stock at all costs. To achieve this, they have put in place a whole arsenal of stringent regulations.

The DPE is the main weapon in the battle against greenhouse gas emissions. Building and housing professionals must comply with precise performance and consumption levels in order to rent or sell their properties. To help them validate the required consumption criteria, they have a high-performance tool at their disposal: DPE software.

Here's a look at its advantages, and a full comparison of the software available on the market.

What are the legal requirements for an ECD?

Every year, new legal obligations concerning the DPE are introduced.

At present, they mainly concern rental, but also the construction and sale of property. We take a closer look. 👉

DPE: definition, calculation and period of validity

Before getting to the heart of the matter, let's go back to basics: what is the energy performance diagnosis?

It's a tool for measuring the energy performance of buildings, based on energy consumption and greenhouse gas emissions.

The assessment classifies properties into energy classes ranging from A (very efficient) to G (very energy-intensive).

Since the new DPE came into force in 2021, calculations are based on fixed criteria for the property (insulation, type of heating or ventilation, etc.), rather than the lifestyle of its current occupants. This change gives a more accurate view of its thermal performance.

💡 A DPE is valid for 10 years. In the event of absence or fraudulent DPE, the landlord is liable to a €15,000 fine .

Obligation to produce and display the DPE

The DPE is primarily for information purposes. It provides information on a property's energy performance, and therefore its potential energy consumption. It is now mandatory for :

  • sale (since 2006) ;
  • rental (since 2007) ;
  • new construction.

If a property is put up for sale or rent, its DPE label must also appear in the property advertisement, and be included in the DDT (dossier de diagnostic technique) before any lease or deed of sale is signed.

Rental ban for DPE classes F and G (and E)

In recent years, new thermal regulations have been introduced to encourage renovation work on energy-hungry homes.

As a result, since 2023, landlords have been prohibited from renting out property with a consumption level of over 450 kWh/m²/year (very poor G label).

Since 2025, the same applies to G-rated thermal huts. Landlords are obliged to carry out renovation work to get out of the G category before letting.

In 2028, it will be the turn of F-rated homes, and in 2034 of E-rated homes.

Why use certified DPE software?

In this new regulatory context, DPE has taken on a very important role. Professionals in the sector need to be able to rely on precise analyses to determine the value of a property and the benefits of renovation work.

It's for this reason that the use of DPE software has become widespread among diagnosticians.

Here are the benefits promised by this tool. 👉

Legal compliance

Only software certified by the French government (notably the Ministry of Ecological Transition) is authorized to produce a legally valid DPE.

As a homeowner or lessor, you must therefore use this type of tool to make sure you comply with the law.

Reliable results

Certified DPE software complies with official calculation methods (3CL-DPE 2021) and takes many parameters into account:

  • insulation ;
  • ventilation ;
  • heating ;
  • hot water production ;
  • surfaces, orientation, etc.

They guarantee highly accurate results.

Automated, up-to-date reports

ECD software is more than just an analysis tool. They also facilitate the layout of results by generating automated reports in line with current standards.

What about free ECD simulators?

Certified ECD software is essential for producing a diagnosis that complies with regulations. But in many cases, you don't need to go all the way. That's where free DPE simulators come in.

In concrete terms, these tools enable you to obtain a quick estimate of a property's energy performance, based on simple data:

  • surface area ;
  • heating ;
  • insulation ;
  • year of construction, etc.

The result has no legal value, but provides a useful initial indication.

These simulators are particularly useful when it comes to preparing an energy renovation project. How can they help? By presenting the work to be prioritized, an estimate of potential energy savings and the evolution of the DPE class.

Another advantage is their ease of use. In just a few minutes, without any particular technical skills, you can obtain an approximate energy class. For agencies, these tools are a way of bolstering a sales argument without immediately hiring a professional.

💡 One of the best representatives of this category of DPE simulators is kelvin, developed to meet the needs of construction companies, design/thermal engineers, renovation professionals and real estate agencies. This intelligent assistant uses AI, 3D modeling and geostatistical data to immediately offer users personalized renovation plans, with three possible scenarios. All that's left to do is integrate the tool into your own websites and advertising campaigns, to capture demand and qualify your prospects.

ECD software: what's important?

The use of DPE software is essential to guarantee full regulatory compliance in the event of sale, rental or construction. However, outside these specific cases, it may be more interesting to use a free DPE simulator, to obtain consistent estimates without having to pay for an energy diagnosis.

The use of simulators is becoming increasingly widespread. But does this mean that AI is likely to replace human diagnostic experts? For the moment, we're a long way from that. Autonomous ECD simulators are a valuable decision-making aid, but not as effective as the combination of conventional ECD software + human expertise.

The diagnostician's profession still has a long way to go!
