In this office and commercial building, fibre-composite materials were employed for the first time to such an extent in a facade. The free-spanning, filigree sun-protection louvers are made of glass-fibre-reinforced polymer (FRP), a material that can be formed at will and is thus suited to double curves and organic transitions. Low own weight and favourable weatherability were further advantages. A metallic finish – which emphasized the technological aesthetics of the building envelope – was achieved by employing a high-gloss lacquer system used in the automotive industry. For the detailing, the building-envelope geometry was parametrically generated. In addition to the design concept, the input included the specifics regarding material and manufacturing techniques, and the results of the structural calculations. The program algorithms were continuously adapted to the progressing planning process.
