Energy transition is a crucial question to respond to the climatic emergency. In France, the law «Climate and resilience»Adopted in 2021, it requires solarization obligations on buildings and infrastructures. These measures aim to reduce the carbon imprint of buildings by encouraging the installation of photovoltaic panels or other green devices.
In this article, we will describe in detail the requirements of this law, the buildings concerned, the calendar of applications and the advantages for the owners.
Why the solarization obligations?
A climatic imperative
France undertakes to reach the Carbon neutrality by 2050. This involves a profound transformation of buildings, which represent 25 % of the national CO2 emissions. By imposing the installation of solar panels or vegetated roofs, the law aims to make these infrastructures more respectful of the environment.
An accelerated energy transition
The solarization obligations allow:
- The local production of renewable energy increases.
- Reduce the consumption of fossil fuels.
- Satisfy the objectives established by the Paris agreement.
