1- Strut sleeves: penetrates the curtain wall and connects to the main structure
2- Fabric mesh frame and sub-frame: supporting the fabric mesh
3- Fabric mesh
4- Slider: allows the mobile tripod to travel along the arms
5- Actuator + Power & Control: cable connection back to the tower
6- Structure arms: supports the whole mechanism
7- Mobile tripod: drives and supports the fabric mesh frames
In detail, also, are reported the horizontal section detail of joints between the Mashrabiya panels, in particular the first referred to a simple contact connection between modules, while the second is the real mechanical joint for each triangular panel.
3.2 Thematic Pavilion at the Expo 2012 in Yeosu, South-Korea designed by SOMA Architecture, Vienna.
The façade covers a total length of about 140 m, and is between 3 m and 13 m high. It consists of 108 kinetic and operable louvers of glass fiber reinforced polymers (GFRP) that fulfil a climatic function and allow different modes of operation depending on the user’s needs. Within the operation mode the louvers are individually actuated and create animated patterns along the façade. The potential choreography ranges from local motion to overall waves affecting the whole length of the façade.
During the day, the lamellas contribute to the shading of the sunlight entering in the building, favoring comfortable lightning and temperature conditions for the visitors and decreasing the consumption of energy of the structure. They operated by energy gained through solar panels on the roof.
After sunset the visual effect of the moving louvers is intensified by linear LED bars, which are located at the inner side of the front edge of the louver.
The dimension of the laminas constituting the façade, directly influence the lightning conditions within the pavilion: the longer the single lamellas, the wider the degree of their aperture and, consequently, the area affected by direct lightning.
