6. Our advice

6.1 Meet the requirements of the RE2020 environmental standard

The RE 2020 environmental regulation came into force on January 1 2022, with the primary aim of improving the energy quality of new buildings by reducing their greenhouse gas emissions. Its retroactive application to older buildings is a means of achieving the following three objectives:

• energy sobriety through the use of green energies and little or no fossil fuels;

• Reducing carbon footprint with biobased materials;

• guaranteed comfort in winter and summer.
