The German artist Susanna Neunast has created an expansive art installation for the exterior facade of the entrance building and parts of the interior for the SEMIZENTRAL RRC in Qingdao. Susanna Neunast was born in 1982 in Aachen. The trained graphic designer reflects aspects of nature and society in their works, using different media. She draws the viewer's attention to seemingly negligible things and covers something special in everyday life in the simplicity of the water. Susanna Neunast captures the fascination and beauty of the water in a true emotional experience and gives unexpected perspectives of perception. In addition to the art the visitors of the RRC are welcomed by visually prepared technically information of the system and the SEMIZENTRAL approach.

The German media reported extensively about Susanna Neunast and her work. On June 7th the German TV station WDR aired a portrait of the artist. You can find the broadcast here. (Please note: The broadcast is available in German for a short time only)
