Bio‐inspirierte kinetische Fassade für den Themenpavillon “One Ocean” EXPO 2012 in Yeosu, Korea

Abstract

Der von SOMA Architecture aus Wien, Österreich entworfene Themenpavillon “One Ocean” ist eines der wichtigsten Gebäude der Expo 2012 in Yeosu, Korea. Die dem Expo‐Gelände und dem Haupteingang zugewandte Seite ist von einer kiemenartigen, mit LED bestückten beweglichen Medienfassade geprägt. Sie stellt einen gestalterischen Bezug zum Meer her und ermöglicht die Lichtsteuerung des Gebäudes.Grundlage der Entwicklung der kinetischen Fassade war die Analyse natürlicher Bewegungsprinzipien. Die Verwendung von glasfaserverstärkten Kunststoffen (GfK) erlaubt große reversible elastische Verformungen und ermöglicht somit eine komplett neue Interpretation wandelbarer Strukturen.Bio‐inspired kinetic façade for the thematic pavilion “One Ocean” EXPO 2012 in Yeosu, KoreaThe Thematic Pavilion “One Ocean”, designed by SOMA Architecture, Vienna, is a major and permanent building for the Expo 2012 in Yeosu, Korea. The façade facing the expo area and the main entrance is conducted as kinetic media façade symbolizing the gills of a fish. The façade therefore illustrates the theme of the Expo “The living ocean and coast” very well.Development of the kinetic media façade was inspired by flexible deformation principles found in plant movements. The project is a role model for a novel application of glass fiber reinforced polymers (GFRP) for deployable structures as well as for advanced biomimetic research and design.

Effect of Gravity on the Scale of Compliant Shells

“…This In accordance with Equation (8), the gravitational force is larger (in magnitude) as the scale of the shell increases. This is appears in Figure 4 with thin shell of larger characteristic dimensions having low values of G i such as for example façade shading shells [16,17,28]. Shells with a characteristic dimension R lower than 0.1 m tend to have Gi > 1.…”

“…The mechanism is oriented to limit the increase of cantilevered length during the movement. For example, the façade of the Yoesu Expo 2012 Pavilion was designed so that the flexible shell elements do not create large overhangs during the out-of-plane buckling deformation [28]. The longest elements are 8 m tall and still able to be elastically deformed repeatedly.…”

Actuated Textile Hybrids Textile smocking for designing dynamic force equilibria in membrane structures

“…Deriving from a research project at ITKE (University Stuttgart) the kinetic façade was finally developed together with the engineering office of Knippers Helbig. This project exemplifies the scalability of a prototype investigation and in addition to that the refined use of material properties together with efficient minimal actuation (Knippers et al 2012) While most of the realised kinetic façade systems devote themselves to one environmental impact such as sunlight, it raises the question if a dynamic envelope such as the one of the Expo Pavilion by Soma could combine the minimal initialising actuation and the consequently amplified passive actuation to form a greater dynamic system such as in the example of the Prairie House. In addition to that and as mentioned earlier, it is noticeable that most kinetic skins are designed for a simplified reaction to mostly only one environmental condition while a translation of the complexity of the outside world into a responsive envelope could not only bring an amplified and unexpected design outcome but could also blur or even dissolve the barrier between architecture and nature.…”

Designing bio-inspired adaptive climatic façades and its effect on daylighting performance of building

“…The building's kinetic façades adapt to the strong winds in the coastal location of the project and the intensity of the lighting inside the building [17].…”
