Successfully renovating the park: contributions from research

For this new edition, a major aspect of this transformation will be at the heart of the discussions: the contributions of research to successfully transform the park.

Building renovation is a challenge that is as essential as it is complex: essential because it is indispensable for living well together and meeting demographic and environmental requirements, complex because it involves a wide range of skills and performance that only collective and multidisciplinary action can mobilize.

Nicolas Naville, director of the Strategic Action Area "Renovation, reliability of the construction process, innovation" at CSTB: "All actors in the value chain must contribute to strengthening the technical, but also economic, performance of operations, and research must inform this collective dynamic."

The research work of the CSTB thus aims to provide stakeholders with a strategic and systemic compass, reliable and tangible scientific benchmarks to progress, remove existing obstacles and contribute to addressing key challenges for the renovation of the building stock:

• Decarbonization and adaptation to climate change
• Renovation strategies and multi-criteria approach
• Actual project performance and improved renovation reliability
• Solutions, materials, construction innovations, focus on bio-based materials
• RGA, structural issues and fire risk in renovation
• Structuring of supply chains, economic models

Each of these themes will be addressed on June 2nd, in the presence of researchers, stakeholders from the territories and the building sector, on the occasion of the CSTB Research Day 2026.
