RESPONSIVE AUTONOMOUS SURFACE STRUCTURES INSPIRED BY PASSIVE MULTI-PHASE PLANT MOVEMENT
The built environment is responsible for a major part of global energy consumption, which makes weather responsive adaptive building envelopes increasingly important. While weather responsive architecture is typically conceived as an added function with numerous sensing, actuating and regulating devices, a fundamentally different design strategy for environmental responsiveness has evolved in biological systems. Hygroscopically actuated plant structures present biological concept generators for the development of weather-adaptive, autonomously actuated, passive building envelopes.
The aim of this research project is to identify construction and functional principles of plant structures at various hierarchical levels that will be abstracted and implemented into adaptive architectural systems. The project focuses on structures that perform multi-phase motion, i.e. sequences of diverse motion steps. The individual movement steps can either take place one after the other or represent individual reactions to different stimuli, which will lead to diverse, versatile bionic kinetic structures. In order to achieve the transfer to technology, the development of a new class of 3D-printable hydrogel assemblies, as well as their integration in new environmentally responsive architectural envelopes will be undertaken.
