The construction industry faces increasing demands for sustainability, cost effectiveness and design flexibility. The Variable Geometry Panels—R2UTechnologies project focuses on the development of composite panels for building facades that combine geometric freedom with sustainability. By using bio-based materials, the consortium aims to minimise environmental impact while maintaining performance standards. The panels were produced by primary manufacturing techniques vacuum-assisted resin infusion. A key innovation in this project is the integration of multi-functional properties into the panels. Lighting solutions and photovoltaic cells are integrated into thermoset panels during the vacuum infusion process. Preliminary results indicate successful integration of these functionalities, with printed electronics and optical fibres being incorporated into hemp and flax reinforced panels, while photovoltaic cells have been embedded in basalt reinforced panels. This project represents a step forward in the development of sustainable, versatile and cost-effective building solutions, contributing to the evolution of the construction industry towards a more environmentally responsible future. The present study was developed in the scope of the Project “Agenda R2U” [C 64487681000000019| Project no 48], financed by PRR–Plano de Recuperação e Resiliência under the Next Generation EU from the European Union.
