As part of the new legislation on the energy performance of buildings, the public authorities have decided to reduce the amount of greenhouse gases emitted by the French housing stock by 40% by 2030. After freezing the rents of housing considered as thermal flats in 2022, the measures are becoming clearer for housing rated G, F and E by 2023, 2028 and 2034. Certainly, these will not be able to be rented for more than 4 months per year at the given deadlines.
To counteract this plague, our architects act mainly on :
- The insulation of the walls with a particular attention to the treatment of thermal bridges.
- The controlled mechanical ventilation hygro B (VMC)
- The replacement of the joineries (double glazing with argon gas) to which humidity sensitive air bars are fixed on the windows of the dry rooms.
- The electric heating system with dry inertia (when we are not in the case of a condominium in which the heating is collective).
A multitude of other options exist in addition to the above (heat pump, solar panels etc.).
The new DPE legislation has the consequence of creating new opportunities on the rental market in particular. It also underlies two issues on which actors like us must act: poor housing and public health issues that are enjoined.
