Conception of louver control for the vertical louvers of the curved western facade. Manufacturing, delivery and commissioning of the louver control, type Elconeq Compact as a decentralized concept.
- Daylight optimised algorithm increases the light yield in the rooms
36 linear actuators, 1200 N, divided into 12 groups, move the vertical louvers. Precise and synchronous slat positioning of the complex wave-shaped curved facade is ensured at all times by the control software

Request
The curved post and beam facade with a high proportion of glass is oriented west-northwest. It is therefore mainly exposed to intensive sunlight in the afternoon. An external 'glass louver shield', which moves with the position of the sun, should significantly reduce the solar loads and still provide daylight. In addition, this shield should make the building reflect dynamism and architectural uniqueness.
System
The RVI glass louver solution shows floor-high glass louvers following the given curved facade shape. The 590mm wide laminated safety glass louvers, consisting of printed and hardened laminated safety glass, 3500mm high, are arranged in segments and combined into defined control groups. When closed, the result is an attractive and visually slightly curved wave that follows the contour of the facade. The building, with a total of 35,000 m2 of office space, was awarded a 5-star V1 design certificate by the Green Building Council of South Africa in 2013 and a 5-star V1 as-built certificate in 2016.
