Faced with the climate emergency, the city of Bordeaux is actively pursuing a drive to reduce CO2 emissions by adopting concrete solutions at the local level. External thermal insulation (ETI) is emerging as an effective lever for significantly reducing the energy consumption of buildings and thus reducing their carbon footprint. In the Gironde region, and more specifically in Bordeaux, specialized companies such as Ravalement Bordeaux – Ravalement33 are fully committed to supporting individuals and communities in this ecological transition.

Since the construction sector is responsible for a significant portion of greenhouse gas emissions, improving the energy performance of facades is a key issue. ETI not only optimizes the thermal comfort of homes but also limits energy losses related to heating and air conditioning. This process, which involves wrapping the exterior of walls with high-performance insulating materials, meets current requirements for sustainable CO2 emission reduction while enhancing Bordeaux’s architectural heritage. The ecological benefits are accompanied by an essential economic advantage, thanks to a significant reduction in energy bills for occupants. In Bordeaux, these interventions are part of a strict regulatory framework aligned with the National Low-Carbon Strategy, aiming for carbon neutrality by 2050. With personalized support and recognized expertise, Ravalement Bordeaux – Ravalement33 offers tailored solutions to ensure meticulous and sustainable work, using materials such as Rockwool, Isover, and solutions from Saint-Gobain.

External Thermal Insulation (ETI): a powerful lever for reducing CO2 emissions in Bordeaux

External thermal insulation (ETI) is an energy renovation technique that involves applying thermal insulation to the exterior facade of a building, followed by a protective and finishing layer. This system offers several major benefits in the face of climate change, helping to reduce CO2 emissions while significantly improving occupant comfort.

Energy and environmental benefits

🌿

• Reduced energy consumption : By limiting heat loss through walls, ETI significantly reduces heating and cooling needs, thereby reducing the consumption of CO2-emitting fossil fuels. 🌍
• Reduced ecological footprint : By promoting the use of high-performance insulation materials, often bio-sourced or recyclable (Rockwool, Knauf Insulation, Perlite), this technique reduces the environmental impact of buildings. 💧 Sustainable facade protection
• : External thermal insulation (ETI) also guarantees better resistance to climatic aggressions, extending the lifespan of buildings and avoiding frequent, more polluting renovations. For example, in the Bordeaux region, where climate variations require effective thermal adaptation, implementing ETI can prevent up to 3 tons of CO2 emissions per year for a 100 m² home. Bordeaux Renovation – Ravalement33 uses certified and reliable materials, such as Rockwool rock wool panels and Isover mineral insulation, guaranteeing performance and compliance with environmental standards. A technique compatible with current regulations.

External thermal insulation (ETI) in Bordeaux is integrated into energy renovation projects that meet the requirements of the RE2020 thermal regulation, aimed at limiting emissions from new and existing buildings. Ravalement33 offers a precise assessment of each façade before renovation, allowing for customized adaptations, as with their work in Ayguemorte or Arès.
