The RE2020 environmental regulation sets energy and environmental performance requirements for buildings.
It was published this summer and will apply progressively to new buildings, including offices, from 2022.
This RE2020 replaces the RT2012 thermal regulation.
What are the targets for RE2020?
- significantly reduce carbon emissions from buildings ;
- prioritize energy sobriety and decarbonization ;
- guarantee comfort in hot weather.
To this end, it is more demanding than RT2012.
Which buildings are affected?
Initially, RE 2020 will apply to residential, office, primary and secondary education buildings.
It applies from :
- January 1, 2022 for residential buildings,
- July 1, 2022 for office buildings and primary and secondary schools;
- January 1, 2023, to extensions and temporary structures.
Until January 1, 2023, RT 2012 requirements apply to temporary buildings and small extensions.
In a second phase, the RE2020 could be applied to other building constructions, including industrial and commercial buildings. As can be expected, a future decree (or decrees?) will introduce the RE2020 requirements for these buildings.
What are the energy and environmental performance requirements?
The construction of any building or part of a building concerned must achieve minimum results in the following areas:
The minimum results are set by building category and geographical location.
So that some of the minimum results will evolve progressively in 2025, 2028 and 2031 to reinforce the RE2020 requirements.
A decree defines the minimum technical characteristics of certain building component assemblies contributing to energy and environmental performance, sanitary quality or thermal comfort.
How is the achievement of these minimum results verified?
A calculation method is used to check that minimum results and technical specifications have been achieved.
However, the project owner can propose an adaptation of this method if it is not applicable due to the specificities of the project, of a system, or due to the creation or consequent modification of a heating or cooling network.
Even more ambitious than RE2020?
As for the RE2020 label, currently under discussion, it will include more stringent requirements for RE 2020 indicators.
