By 2025, Bordeaux will be fully committed to the energy transition thanks to the reinforced adoption of the RE2020 regulation, which has a particularly impactful impact on external thermal insulation (ETI). This regulation, aimed at reducing the carbon footprint of construction and improving the energy performance of buildings, is now an essential standard for all eco-construction and sustainable renovation projects in the Bordeaux metropolitan area. The use of high-performance thermal insulation, as part of a construction site that complies with RT 2020 standards, has become the best solution for increasing thermal comfort while ensuring a healthy and energy-efficient home.
In Bordeaux, owners and professionals are now aware of the importance of aligning with these standards, which take into account the entire life cycle of materials and equipment. The RE2020 regulation will impose stricter requirements regarding carbon emissions and thermal performance, with particular attention paid to summer comfort management. This is driving industry players to seek innovative and sustainable solutions. Bordeaux Renovation – Ravalement33, a renowned specialist in renovation and facade renovations in Gironde, adapts perfectly to these requirements to offer its clients a service that meets regulatory requirements and their expectations.
Furthermore, the regulations establish a comprehensive approach integrating life cycle analyses, precise diagnostics, and adapted techniques to ensure that each external thermal insulation project best meets energy performance criteria. Bordeaux, with its specific urban and climatic conditions, is becoming a testing ground for these new practices, giving new impetus to sustainable home renovation.

Understanding the RE2020 regulation and its impact on external thermal insulation in Bordeaux
The RE2020 regulation, in effect since 2022 and revised in 2025, sets the mandatory framework for new construction and sustainable renovation in Bordeaux, particularly for external thermal insulation applications. It is based on three essential objectives for better eco-construction:
- 🌿 Reducing carbon footprint : limiting greenhouse gas emissions throughout the building’s life cycle.
- ⚡ Improving energy performance : through enhanced thermal insulation, airtightness, and the integration of renewable energies. 🌞
- Ensure summer comfort: By promoting passive solutions such as natural ventilation and shading, thus minimizing the use of air conditioning. This translates into strict thresholds for both carbon emissions and energy efficiency. For example, for single-family homes in Bordeaux, the maximum carbon impact drops to 530 kg of CO² per m², compared to 640 previously. For multi-family housing, this value is lowered to 650 kg CO²/m². For illustration purposes, the table below details these changes by building type:
🏠 Building type 🌱 Carbon emissions 2022 (kg CO²/m²)🚀 Carbon emissions 2025 (kg CO²/m²)
| Single-family or semi-detached houses | 640 | 530 |
|---|---|---|
| Multi-family housing | 740 | 650 |
| This development is creating a real revolution in housing, pushing professionals to favor high-performance, environmentally friendly insulation materials and innovative techniques. External thermal insulation (ETI) in Bordeaux is therefore the best solution for a sustainable renovation that complies with RT 2020 standards. Ravalement Bordeaux – Ravalement33 provides comprehensive support, including diagnostics, personalized advice, and the installation of thermal insulation adapted to each type of facade, thus guaranteeing complete customer satisfaction. | Discover the importance of regulation in different sectors, its impact on safety, the economy, and consumer protection. Learn about the challenges and practices of regulation to better understand its role in our society. | RE2020 Technical Requirements for External Thermal Insulation in Bordeaux |
RE2020 significantly strengthens thermal performance standards, specifically incorporating the characteristics of Bordeaux. The energy carbon index thresholds are therefore limited, particularly for multi-family housing connected to a district heating network. Key criteria include optimizing thermal insulation, both to limit energy loss and the environmental footprint.

🔹 The choice of low-carbon thermal insulation, favoring bio-sourced or recycled materials.
🔹 Quality of installation, with treatment of thermal bridges and good facade sealing.
🔹 Summer comfort, thanks to techniques capable of protecting against overheating.
- The following table shows the energy carbon index limits in 2025 in the context of Bordeaux:
- 🏢 Building type
- 🌍 Max. energy IC 2022 (kg CO²/m²)
⚡ Maximum energy efficiency index 2025 (kg CO²/m²)
| Individual houses | 160 | 160 |
|---|---|---|
| Multi-family housing (district heat networks) | 560 | 320 |
| Multi-family housing (other cases) | 560 | 260 |
| This strengthening of standards encourages sustainable renovations using the best available thermal insulation and appropriate installation methods.
