Understanding the RE2020 environmental regulations

In 2020, France has abandoned its thermal regulations in favour of environmental regulations, the RE2020. What impact will this have on the construction industry, including Polimmo La Maison? Here are our answers.

What is the goal regulations?

The French building sector alone is responsible for 44% of energy consumption and 25% of CO2 emissions. Since 1974, various thermal regulations have been put in place to gradually move towards more energy-efficient buildings. The most recent, prior to the RE2020, is RT2012, the result of the Grenelle Environment Round Table.

The RT2012, demanding regulations for the construction sector

architectsIn 2007, the Grenelle Environment Forum set France a highly ambitious target: to reduce its greenhouse gas emissions by a factor of four by 2050. To achieve this goal, two main avenues have been explored:

  • build new buildings that produce more energy than they consume, starting in 2020
  • mass renovation of existing buildings to improve their energy performance.

The construction industry, and the building sector in general, are therefore in the front line. RT2012 has three objectives:

  • Bbiomax or bioclimatic building requirement: minimum energy efficiency for buildings
  • Cepmax or a maximum conventional consumption of primary energy, which covers heating and lighting consumption, among other things
  • Ticref, summer comfort in non-air-conditioned buildings



The transition to RE2020

The ELAN law (Evolution of Housing, Development and the Digital Economy) provides for the application of the RE2020 to all new buildings in order to continue to improve the energy performance and comfort of new constructions, and to reduce their carbon impact. To achieve this, three objectives have been set:

  • reduce the climate impact of new buildings throughout their life cycle
  • continue to reduce energy consumption and improve the energy performance of new buildings
  • adapt the living and working environment to climate change, particularly in summer.

To achieve these objectives, the entire construction industry needs to undergo radical change, from energy sources to construction techniques.

Who is concerned by the RE2020 regulation?

Firstly, single-family homes and multi-family housing, then offices and primary and secondary schools, and finally certain tertiary buildings such as shops and gymnasiums.

Polimmo La Maison is therefore concerned by the application of the RE2022 regulations for the construction of its detached houses. We are, of course, doing everything we can to apply the directives of these regulations.
