Design and construction principles in nature and architecture
This paper will focus on how the emerging scientific discipline of biomimetics can bring new insights into the field of architecture. An analysis of both architectural and biological methodologies will show important aspects connecting these two. The foundation of this paper is a case study of convertible structures based on elastic plant movements. Nature, however, exploits this principle and uses it actively tomobilize certain functions. Based on the first physical models and numerical simulations, a prototype facade shading system called Flectofin® was developed and registered for a patent (Lienhard et al.; Flectofin: a nature based hinge-less flapping mechanism; Bioinspiration & Biomimetics 6(2011)4, patent application). The Flectofin® lamellas consist entirely of fibreglass-reinforced plastic, which offers high tensile strength combined with low bending stiffness, allowing for large elastic deformations. Because the system functions without a straight turning axis but with a bent backbone, it can also be adapted to facades with curved geometries. This represents a significant expansion of possible future applications. Another important advantage is the shading system not having any maintenanceintensive parts such as sliding joints or hinges. This reduces costs for maintenance and care.
