Following the success of previous editions in Madrid (Spain) in 2014, Brussels (Belgium) in 2016, Visby (Suède) in 2018, Benediktbeuern (Germany) in 2022, and Krems (Austria) in 2024, Cerema is pleased to announce the 6th International Conference on Energy Efficiency in Historic Buildings (EEHB), which will take place in Strasbourg (France) in 2026.

As the struggle against climate change becomes increasingly urgent, the role of the building sector is crucial in achieving global CO₂ reduction goals. Historic buildings represent a significant part of our built environment, accounting for one-fourth of the building stock in Europe. They define the nature and identity of many cities and can only remain if preserved as thriving and functional spaces. To safeguard this heritage for future generations, we need to identify energy retrofit approaches and solutions that align with conservation principles. These solutions should preserve historic and aesthetic values while enhancing comfort, reducing energy bills and minimizing environmental impact.

EEHB 2026 will bring together researchers, practitioners, and policymakers to explore the latest advancements in energy efficiency for historic buildings. This 6^th conference will focus on key topics such as climate change impact on indoor climate, bio-based materials, AI and digital tools for heritage retrofit, Horizon Europe projects, and inspiring case studies. In addition, sessions will address building physics applied to historic buildings (hygrothermal transfer, material properties, etc.), training and guidelines for professionals, and the role of social sciences in retrofitting historic buildings.

Through these diverse themes, EEHB 2026 aims to foster knowledge exchange and encourage innovative solutions that enhance sustainability while safeguarding the authenticity of historic buildings.
