Biomimetic Research for Architecture and Building by Jan Knippers, Klaus G. Nickel, Thomas Speck

By Jan Knippers, Klaus G. Nickel, Thomas Speck

This e-book includes a primary survey of the Collaborative study middle SFB-TRR 141 ‘Biological layout and Integrative buildings – research, Simulation and Implementation in Architecture’, funded via the Deutsche Forschungsgemeinschaft for the reason that October 2014. The SFB-TRR 141 offers a collaborative framework for architects and engineers from the collage of Stuttgart, biologists and physicists from the college of Freiburg and geoscientists and evolutionary biologists from the college of Tübingen. The programm is conceptualized as a discussion among the disciplines and is predicated at the trust that that biomimetic learn has the capability to steer every person concerned to new findings some distance past his person achieve. over the last few a long time, computational equipment were brought into all fields of technological know-how and expertise. In structure, they allow the geometric differentiation of establishing elements and make allowance the fabrication of porous or fibre-based fabrics with in the community adjusted actual and chemical homes. contemporary advancements in simulation applied sciences concentrate on multi-scale versions and the interaction of mechanical phenomena at quite a few hierarchical degrees. within the normal sciences, a large number of quantitative equipment protecting different hierarchical degrees were brought. those advances in computational equipment have opened a brand new period in biomimetics: neighborhood differentiation at quite a few scales, the most characteristic of common structures, can for the 1st time not just be analysed, yet to a undeniable quantity even be transferred to construction building. Computational methodologies let the direct trade of data among fields of technological know-how that, beforehand, were broadly separated. therefore they result in a brand new method of biomimetic study, which, with a bit of luck, contributes to a extra sustainable improvement in structure and development building.

The Lotus research led to the unexpected geometry and physics of the microscopic egg-beater-shaped hairs in the drag-reducing airretaining surfaces of the floating fern Salvinia (Figs. 20). 30 W. Barthlott et al. Fig. 17 The Giant Arum (Amorphophallus titanum) reaches 3 m in height and has the largest blossom in the plant kingdom. The giant pleated “petal” (spathe) weighs less than 4 kg: the largest light-weight construction amongst plants or even in organisms. In its habitat, the tropical rainforest, it attracts visiting insects like a torch: the central column heats up periodically at night and works as a convection device evaporating an unpleasant odour (for humans) to attract pollinators.

Therefore, we suggest the use of the term parabionics for products or processes pretending to be bionic but having neither a bionic function nor a bionic origin. g. Ingo Rechenberg), which has a different meaning and connotation. Parabionics plays many important roles from product marketing (Fig. 13, see also Barthlott et al. 2016) to fundraising in research programs. As a biologist, one is tempted to classify this phenomenon under “mimicry”, namely deceptive products that pretend to be something else, as in the Wasp Spider Argiope in Fig.

In such environments with frequent rainfall, a few raindrops adhering to the ultrathin wings of Meganeura would have made these structures non-functional. Therefore, Meganeura’s wings most likely had a hierarchically structured superhydrophobic surface. Interestingly, this argument reflects a process of back-casting from properties of an extant organism, understood through bionics, to those of fossil species that became extinct millions of years ago. How many potential living prototypes have been lost during the course of Earth’s history?
