In the context of the new legislation on building energy performance, the authorities aim to reduce greenhouse gas emissions from the French real estate sector by 40% by 2030. After freezing rents for housing units considered as thermal strainers in 2022, measures are being specified for properties rated G, F, and E by 2023, 2028, and 2034. Undoubtedly, by the specified deadlines, these properties cannot be rented out for more than 4 months per year.
To counteract this issue, our architects primarily focus on :
- The insulation of the walls with particular attention to addressing thermal bridges.
- The controlled mechanical ventilation hygro B (CMVH).
- Replacing the windows (double glazing with argon gas), to which adjustable humidity-sensitive ventilation grilles are attached on the windows of dry rooms.
- The dry inertia electric heating system (when we are not in the case of a condominium where heating is collective).
A multitude of other options exist in addition to the aforementioned elements (heat pumps, solar panels, etc.).
The new DPE legislation has the consequence of creating new opportunities in the rental market in particular. It also underpins two issues on which actors like us must act: poor housing and the associated public health issues.
