Make your building greener and cheaper
The energy transition is more relevant than ever. Renovating your building is not only a way of reducing greenhouse gas emissions, it's also an effective way of saving on energy bills thanks to lower building energy consumption.
Take advantage of a DPE rating bonus
The DPE (Diagnostic de Performance Énergétique) rating is a key measure of a building's energy consumption and carbon footprint. Graded from A to G, this rating plays a crucial role in real estate. It :
- assesses energy consumption: the DPE rating provides an overview of a property's energy expenditure and environmental impact, crucial for deciding what work needs to be carried out
- increases the real estate value of your property: a favorable DPE enhances the value of a property by optimizing its durability and reducing energy costs, while energy-hungry properties risk losing their appeal
- enables rental eligibility: complying with energy reforms has become imperative, with DPE criteria influencing the possibility of renting out a property. Class G properties will be banned from rental as of January 2025, followed by class F in 2028, and class E in 2034.
Three-step renovation strategy for a higher DPE rating
Before undertaking any renovation work, it's essential to take a few preliminary steps:
- carry out an energy audit: before any work is carried out, it's important to assess your home's energy performance. Identify any weaknesses in insulation, heating and ventilation thanks to a comprehensive diagnosis.
- look into financing the work: explore the financial aid available for energy renovation, such as MaPrimeRénov' or CEE. An energy advisor can guide you through the administrative formalities.
- Planning the work: plan each stage of the project carefully to ensure that it is carried out properly. Hire RGE-certified craftsmen to ensure that your project meets the standards required to qualify for subsidies.
Maximize your DPE: the most beneficial interventions
To get a better DPE rating, focus in particular on :
- thermal insulation: better insulation of attics and walls, and upgrading to high-performance glazing, reduces energy consumption and improves comfort;
- modern heating: replacing old boilers with more economical solutions such as heat pumps or biomass boilers reduces greenhouse gas emissions;
- efficient ventilation: adopt a double-flow ventilation system to maintain an energy balance while ensuring good indoor air quality.
