Together with the architecture company topotek1, which is based in Berlin, a screening fence was developed. Big spans, low noise pollution in case of ball impacts and the possibility of coloring the mesh in different shades of green were the main criteria for the mesh selection of the architects. The sports facility Heerenschürli is the only facility which is fulfilling the demands of an international baseball arena. It is also the home base of the three Zurich clubs Barracudas, Challengers and the Lions. The Geobrugg screening fence covers 9 soccer and 1 baseball field. The partially with double layers of mesh mounted fence is not only a screening fence but is furthermore also seen as an architectural element. More than 8’000 m2 of mesh have been installed in two different shades of green color. Totally five different shades of green were used for the facility to make the appearance unique to visitors. The Geobrugg screening fence at the sports facility Heerenschürli is currently the biggest one in use.
