Stadtverwaltung St. Ingbert
Architect: Schneider + Schumacher Architekturgesellschaft mbH, Frankfurt
Work Phases: 1-6
Total Area: 2.000 m² Fassadenfläche
The natural stone facade of the Town Hall in St. Ingbert – an exemplary office building of the 1960s – needed to be refurbished. The key feature of the new concept is the versatile second skin sun protection. The facade facade construction that was developed in cooperation with the architects consists of utterly filigree stainless steel fins. These are built as suspended construction and are connected to the attic by cantilevering beams.
The sun protection components fold horizontally and consist of flat steel frames that have been covered with a translucent skin made of poly spectrally coloured stainless steel fabric. The appearance of the facade changes due to solar altitude and perspective. It ranges from translucent veil to opaque skin. The computational generated and CNC controlled impressed pattern provide the facade with a continuated ornament when the fins are closed and at the same time give the filigree fabric the needed stability.
