La RE2020 impose des exigences plus strictes en matière d’isolation thermique que les réglementations précédentes. Elle vise notamment à :
  • Reduce the primary energy consumption of new buildings by 20% compared to the RT2012
  • Reduce greenhouse gas emissions from new buildings by 40% compared to the RT2012
  • Achieve carbon neutrality for new buildings by 2050
En plus de la réglementation thermique, il existe également des aides financières pour encourager les particuliers à réaliser des travaux d’isolation thermique. Ces aides peuvent prendre différentes formes, telles que des subventions, des prêts à taux zéro ou des crédits d’impôt. Si vous envisagez de réaliser des travaux d’isolation thermique, il est important de vous renseigner sur la réglementation en vigueur et sur les aides financières disponibles. Vous pouvez également faire appel à un professionnel qualifié pour vous conseiller et vous accompagner dans votre projet. Here are some key points of the RE2020 regulation :
  • New buildings must comply with stricter energy performance requirements.
  • Thermal bridges must be eliminated or minimized.
  • The use of renewable energies is encouraged.
  • Energy performance checks of buildings are carried out at delivery and during operation.
Thermal insulation is a profitable investment that allows you to reduce your energy bills, improve your quality of life, and contribute to environmental protection. Do not hesitate to contact a professional for advice and assistance with your project.
