DPE: a well-prepared visit for greater efficiency

arrow_back Back

Since 2006, the Diagnostic de Performance Énergétique (DPE) has been essential for assessing the energy efficiency of buildings, as well as their impact on greenhouse gas emissions. This diagnosis is mandatory when selling or renting property. Here are a few essential tips to help you prepare for the visit of your DPE diagnostician, so as to guarantee accurate and reliable results.

Understanding the importance of the DPE

The Energy Performance Diagnostic (DPE) is an essential tool for assessing the energy performance of a home or building. It focuses on two key indicators: energy consumption, expressed in kWh/m²/year, and greenhouse gas emissions, indicated in kg CO2/m²/year. Like the energy labels on household appliances, DPE results are classified from A (high energy performance) to G (high energy consumption).
The main aim of the DPE is to make homeowners and tenants more aware of the energy efficiency of their home. This awareness is crucial, as it encourages residents to consider energy-saving renovations to optimize their home's performance. Preparing for the DPE visit therefore plays a decisive role in improving the energy efficiency of buildings, helping to reduce both energy costs and environmental impact.

A thorough examination of the building

The diagnostics professional usually begins by assessing the building's configuration and surface area, including the number of rooms and floors. This initial assessment is crucial to accurately measure the total living space. During this visit, the expert also analyzes the building's thermal inertia and ventilation system, essential aspects in understanding the property's energy context. This in-depth understanding is essential to identify the building's specific characteristics, guaranteeing a reliable and comprehensive diagnosis. In addition, the diagnostician details the following elements:

  • living area and areas exposed to outside temperature variations, such as entrances, doors, windows and exterior walls
  • type of glazing and insulation efficiency
  • The condition of the boiler and associated systems, including radiators, hot water production and underfloor heating.
  • Temperatures measured in different areas of the property, to assess heating uniformity
  • The presence of thermal bridges and poorly insulated areas, which can affect energy performance
  • The level of natural lighting in the building, a factor influencing well-being and energy consumption.

Documents to be supplied

Before the diagnostician visits your property, it's crucial to prepare all the necessary documents. This will speed up the inspection process and ensure that you have access to all the information required. Be sure to gather the following items:
  • Title deed showing year of construction
  • Living area (shab)
  • Tax ID number, particularly useful for rental properties
  • Co-ownership regulations and, if available, the building's energy audit or collective DPE (DPE collectif)
  • Building plans to help the diagnostician understand the structure of the property
  • Energy consumption invoices (heating, electricity, gas) for the last three years
  • Invoices for recent work, including insulation, boiler replacement or installation of solar panels
  • If available, previous DPEs provide a useful basis for comparison.
Don't forget to :
  • check that electrical switches and sockets are working properly
  • check for water leaks and test household equipment
  • inspect heating and air-conditioning systems
  • Examine windows and doors, and look for signs of damp on walls and ceilings.
These checks help to quickly identify and resolve any potential problems, simplifying the diagnostician's task. By following these recommendations to prepare for the visit, you'll facilitate the assessment and potentially improve the energy performance of your home.
