At Advanced Building Skins 2025, AEGIR presented how façade retrofit can move beyond one-off solutions and become a scalable, design-driven system. Drawing from the 4 AEGIR demo sites, the presentation highlighted the Spanish site as a focused example, showing how architectural decisions grounded in performance data and engineering input translate into buildable, legible, and adaptable façade solutions for real buildings. Several AEGIR partners collaborated to deliver a session titled “Scaling Up Sustainable Renovations – AEGIR Perspectives,” covering a wide range of topics. Their presentations are available for download below. Presentations by AEGIR partners: 1. Sustainable renovations based on solutions coming from the AEGIR project (Julen Astudillo, Tecnalia) 2. Modular and digital innovations in sustainable renovations (Tom Minderhoud, UNStudio) 3. Integration of active technologies in the building envelope (Arnaud Jay, CEA) 4. Integrating urban mining and reuse strategies in façade renovation (Thaleia Konstantinou, TU Delft) 5. Integrating digital technologies and a constellation of services (Nicolas Pastorelly, CSTB) 6. Scaling up sustainable renovations with AEGIR solutions (Bard Rama, ICLEI)
