“…Eine signifikante Hebelwirkung zum Klimaschutz und zur Klimaanpassung urbaner Architektur kann den Gebäudehüllflächen der stetig höher werdenden Gebäude zugeschrieben werden. Aufgrund ihres großen Oberflächenanteils weisen diese ein hohes Potenzial zur Verbesserung des urbanen Regenwasser‐ und Temperaturmanagements auf Gebäude‐ und Stadtraumebene auf [49].…”

“…Sie stellen einen integralen Ansatz dar, das Regenwasser‐ und Temperaturmanagement effektiv und wirtschaftlich zu verbessern, ohne weitere städtische Bodenflächen zu beanspruchen. In Verbindung mit einer automatisierten Kontroll‐ und Regelungsstrategie zur effizienten Nutzung der Regenwassererträge im und am Gebäude können signifikante Wasser‐ und Energieeinsparungen erzielt werden [49, 52]. Durch den Einsatz hydroaktiver Hüllen können deren Eigenschaften zudem zur positiven Beeinflussung des ökologischen Fußabdrucks genutzt werden [50, 51].…”

Wie kann künftig mehr umbauter Raum mit weniger Ressourceneinsatz bei gleichzeitig deutlich reduzierten Umweltwirkungen geschaffen werden? Mit dieser Frage beschäftigen sich 14 Institute der Universität Stuttgart im Rahmen des Sonderforschungsbereichs (SFB) 1244. Die beteiligten Forschenden sehen in der Adaptivität ein großes Potenzial für einen Paradigmenwechsel in der gebauten Umwelt. Ihr Bestreben ist es, die Energie-, Material-und Emissionsbilanz von Tragwerken und Fassaden über den gesamten Lebenszyklus eines Gebäudes durch die Integration adaptiver Elemente zu optimieren.

Funicular structures transfer their loads through axial forces. This feature makes them more efficient than structures subject to shear and bending, but in turn, the loads determine the structural shape and vice versa. Nevertheless, structures are often subjected to loads varying in time and funicularity requires adaptation of shape. Flexible tensile structures e.g. cables and textiles adapt their forms to loads spontaneously. In contrast, the bending stiffness of compression structures does not allow spontaneous change of shape, thus more structural material is needed to prevent bending-induced mechanical failure. At the same time pure compression or mixed structures offer better solutions in some structural applicationsThe purpose of this study is to use sensory feedback about a structure's deformations to guide the structure to a funicular shape which is time-dependent and unknown to the controller. We consider a discrete model of a cantilever structure composed of rigid bars and elastic joints equipped with sensors measuring bending moments and rotary actuators. We aim to guide the structure towards different funicular configurations when the external load is unpredictable and not directly observable. The efficiency of the system under different control policies is studied with emphasis on stability under constant load and ability of the controller to react to rapidly changing loads.

“…The state of the art in climate-resilient façade concepts does not offer any integral approaches for combining climate mitigation and adaptation strategies, while simultaneously addressing both climate impacts on urban architecture. A further description of existing climate-resilient façade concepts in terms of rainwater harvesting (RWH) and evaporative cooling (EC) can be found in Reference [8].…”

Extreme heat and heavy rainfall events with severe inundations have a significant impact on urban architecture, resulting in considerable personal injuries and material damage. Nowadays, the proportion of façade surface in urban areas with tall buildings is substantially larger than the proportion of horizontal roof or ground surface areas. A high leverage effect on climate resilience and sustainability of buildings and cities can therefore be attributed to the building envelopes. Whereas the majority of existing façades are designed to provide only minor qualities at a district or urban level, research at the Institute for Lightweight Structures and Conceptual Design (ILEK) at the University of Stuttgart focuses on development of a new type of hydroactive lightweight façades incorporating climate change mitigation and adaptation strategies. A textile‐ and film‐based façade element called HydroSKIN is capable of providing a retention surface on the envelope of the building. With a minimal amount of embedded mass, energy, and CO2 emissions, the façade add‐on element is suitable for both new and existing buildings. HydroSKIN combines rainwater harvesting (RWH) and run‐off water reduction by retaining the precipitation water that strikes the façade with a time‐delayed evaporative cooling (EC) of the building and its environment.
