TO WHAT TYPE OF BUILDING DOES THE RT 2020 REGULATION APPLY?
The RT 2020 thermal regulation came into force at the beginning of 2021. This new mandatory CMV standard applies only to
certain types of buildings.
Indeed, it frames all new constructions and aims to erect :
● positive energy buildings (BEPOS)
● and passive houses.
While BEPOS produce more energy than they consume, passive houses consume little energy and can even recycle the energy consumed.
HOW TO MEET THE CURRENT THERMAL REGULATIONS?
The regulation VMC RT 2012 is still effective for buildings for which the building permit was submitted on January 1, 2013.
For the rest, it is the RT 2020 regulation that takes over. The compulsory RT 2020 VMC regulation therefore concerns BEPOS and passive houses. The following are the compliance requirements:
● For passive houses: intelligent management of consumption and the use of renewable energy by installing photovoltaic panels, for example.
● For BEPOS homes: heating consumption < 12kWhep/m2, ability to produce energy for heating, DHW, cooling, lighting and other utilities.
The 2020 thermal regulations encourage the use of free energy sources to meet domestic needs. On this point, the installation of a mechanical ventilation with thermodynamic double flow makes it possible to restore heat and freshness and thus to save in heating and air-conditioning.
