What is Thermal
Regulation 2020?

Thermal Regulation 2020, more commonly known in French as RT 2020, is intended to improve the energy performance of all buildings until they reach passive-energy, also known as positive-energy, standards. In other words, buildings built after 2020 must create at least as much energy as they consume.

RT 2020 requirements
Increasingly precise standards are being developed. In order to qualify for RT 2020, builders must produce a building whose total annual consumption of primary energy may not exceed 100 kWhep per m2. This primary energy consists mainly of that needed to run water heaters, electrical appliances and lighting. Efforts to insulate and ventilate must be made to obtain this goal. Future standards also include requirements to produce renewable energy that must equal or exceed the energy needs of the house or building.

Changes since RT 2012
First of all, the new thermal regulations aim to improve residential comfort, particularly sound insulation and air quality. Building professionals will have to opt for more environmentally-friendly materials such as peat and cellulose wadding that have longer lifespans than mineral insulation while still offering excellent value for money. New concepts, such as heated window panes, a window that also acts as a radiator, are also being developed. The RT 2020 will have consequences for the entire building industry: from suppliers of building materials to builders and all of the other industry professionals in between.
