Insbesondere solaraktive Gebäudehüllen bieten Potenzial, durch gezielte Steuerung von Sonneneinstrahlung, Belüftung und Tageslichtnutzung den Energieverbrauch zu senken und gleichzeitig den Nutzerkomfort zu erhöhen. Das Forschungsprojekt FlectoLine-Fassade verfolgt das Ziel, intelligente, materialbasierte adaptive Fassadenlösungen ohne klassische Antriebs- und Steuerungssysteme zu realisieren. Im Zentrum stehen dabei flexible Faltelemente, die auf bioinspirierten, nachgiebigen Mechanismen basieren und sich durch die elastische Verformbarkeit von FVK-Platten ohne Gelenke auszeichnen. Durch integrierte pneumatische Aktuatoren, präzise programmierte Materialsysteme und gezielte Differenzierung der Steifigkeiten kann eine kontrollierte Faltbewegung bis 90° erreicht werden. Neben einem Hybridmaterialsystem wurde eine thermoplastische Variante entwickelt, die einfacher zu fertigen und recycelbar ist. Umfangreiche Belastungstests belegen die Langlebigkeit beider Systeme. Ergänzend wurden flexible Photovoltaikzellen integriert, um Energie zu gewinnen. Ein digitaler Zwilling mit Sensorik und Wetterdaten steuert die Fassade in Echtzeit. Der Demonstrator mit 101 individuell verformbaren Elementen auf 83,5 m2 zeigt die technische Umsetzbarkeit und das energetische Potenzial adaptiver Fassadentechnologien der nächsten Generation.\r\n\r\nIn view of the increasing energy demand in building operations, the development of adaptive façade systems is gaining growing importance. In particular, solar-active building envelopes offer potential to reduce energy consumption through targeted control of solar radiation, ventilation, and daylight use, while simultaneously increasing user comfort. The research project FlectoLine Façade aims to realize intelligent, material-based adaptive façade solutions without conventional drive and control systems. At its core are flexible folding elements based on bio-inspired, compliant mechanisms characterized by elastic deformability of fibre-reinforced composite (FRC) panels without joints. Through integrated pneumatic actuators, precisely programmed material systems, and targeted differentiation of stiffness, a controlled folding movement of up to 90° can be achieved. In addition to a hybrid material system, a thermoplastic variant was developed that is easier to manufacture and recyclable. Extensive load tests demonstrate the durability of both systems. Furthermore, flexible photovoltaic cells were integrated to generate energy. A digital twin with sensors and weather data controls the façade in real time. The demonstrator with 101 individually deformable elements covering 83.5 m2 demonstrates the technical feasibility and the energetic potential of next-generation adaptive façade technologies.","annote":"","author":[{"family":"Körner","given":"Axel"},{"family":"Martin","given":"Edith Anahi Gonzalez San"},{"family":"Born","given":"Larissa"},{"family":"Ridder","given":"Matthias"},{"family":"Moser","given":"Stephan"},{"family":"Weitlaner","given":"Robert"},{"family":"Gresser","given":"Götz T."},{"family":"Knippers","given":"Jan"}],"citation-label":"Korner.2025","collection-editor":[],"collection-title":"","container-author":[],"container-title":"Stahlbau","documents":[],"edition":"","editor":[],"event-date":{"date-parts":[["2025","10"]],"literal":"2025"},"event-place":"","id":"b2a7a7dfa98271586f9e8d6bf1b43224itft-puma","interhash":"f15df303e6bf81a97566df307eddcfc2","intrahash":"b2a7a7dfa98271586f9e8d6bf1b43224","issue":"","issued":{"date-parts":[["2025","10"]],"literal":"2025"},"keyword":"Aktuatorik Bionik Fassade Kunststoff Lernen Mechanismen Photovoltaik Zwilling actuation adaptive biomimetic compliant digital digitaler faserverstärkter façade fibre learning machine maschinelles mechanisms nachgiebige photo plastic pneumatic pneumatische reinforced responsive twin voltaic","misc":{"language":"ger eng","file":"K{\\\"o}rner, Martin et al 2025 - FlectoLine:Attachments/K{\\\"o}rner, Martin et al 2025 - FlectoLine.pdf:application/pdf","issn":"0038-9145","doi":"10.1002/stab.70009"},"note":"","number":"","page":"","page-first":"","publisher":"","publisher-place":"","status":"","title":"FlectoLine: eine adaptive Fassade für nachhaltige Architektur\r\nFlectoLine: A responsive Façade for sustainable architecture","type":"article-journal","username":"itft-puma","version":"","volume":""},"44f62035c93a24f0d6329be720db5d6dmariedavidova":{"DOI":"","ISBN":"","ISSN":"","URL":"http://architecturemps.com/wp-content/uploads/2018/12/AMPS-Proceedings-12-Critical-Practice-in-an-Age-of-Complexity-1.pdf","abstract":"Unlike preceding “autonomous house systems” sysloop is cross-layered and highly scalable concept of “allopoietic system”, a system that is autonomous though dependent on the exchange across its environment (Dekkers 2015). This is performed through three types of co-design: • co-designing of trans-disciplinary co-authors; • co-designing of environment from which it is learning, users included; • co-designing of artificial intelligence and big data. At the scale of local environment, sysloop is focused mainly on interrelations of individual life space qualities, providing contextual autonomous behaviour across many aspects such as climate, light, sound, smell, safety, access control, etc. Due to such scope, the trans-disciplinary team of experts developing sysloop technology is evolving in time in reference to related fields. We specify key aspects of an alternative information system with ability to make decisions based on automated interpretation of meanings, instead of (conventional) symbol processing. We verify such information system in practice of environment automation, introducing technological support of overlapping values such as information hygiene, lifelong learning, aesthetics, overall comfort, etc. Such environments are integrated at “buildings” units scale in phenomenological terms and at “industrial” units scale focused on adaptive automation and reliability engineering, both processing micro-sensorial data and performing qualified decision making in real-time. These together with other big data available are integrated to support the “cities’” scale layer. This layer is to serve for informed city planning and emergency situations solutions, including automated, personalised assistance to individual citizens, etc. This multi-scaled system is feedback looping across its layers of scales and types of co-design and thus evolving by data and most importantly, its ever-changing relations. It gives to the term “smart buildings” its meaning across the scales towards sustainable development, performance and ecosystems. The authors, among all the team, built the first prototypical family and office building for real-world testing and further development. This “real life co-design laboratory” is elaborated at separate paper for this conference.","annote":"","author":[{"family":"Pánek","given":"Karel"},{"family":"Davidová","given":"Marie"}],"citation-label":"noauthororeditor","collection-editor":[{"family":"Bean","given":"Jonathan"},{"family":"Dickinson","given":"Susannah"},{"family":"Ida","given":"Aletheia"}],"collection-title":"","container-author":[{"family":"Bean","given":"Jonathan"},{"family":"Dickinson","given":"Susannah"},{"family":"Ida","given":"Aletheia"}],"container-title":"","documents":[],"edition":"","editor":[{"family":"Bean","given":"Jonathan"},{"family":"Dickinson","given":"Susannah"},{"family":"Ida","given":"Aletheia"}],"event-date":{"date-parts":[["2018"]],"literal":"2018"},"event-place":"","id":"44f62035c93a24f0d6329be720db5d6dmariedavidova","interhash":"662f443905d1502dd9ff1e6a844d1474","intrahash":"44f62035c93a24f0d6329be720db5d6d","issue":"","issued":{"date-parts":[["2018"]],"literal":"2018"},"keyword":"architecture codesign intelligent learning machine myown responsive systems","note":"","number":"","number-of-pages":"9","page":"132-141","page-first":"132","publisher":"University of Arizona","publisher-place":"","status":"","title":"sysloop","type":"chapter","username":"mariedavidova","version":"","volume":""}}
