Jena, Germany

Built in 1972 and completely refurbished in 1999, JenTower is one of Jena's landmarks. The tower in the center of the university town is currently the tallest office building in the new federal states of Germany and the first building in Thuringia to be certified by the German Sustainable Building Council (DGNB).

From October 3 to 11, 2015 JenTower became the stage for a spectacular lighting installation from the artist Florian Licht. As a digital response to one of the oldest means of communication – beacons – his LEUCHTTURM media installation visualized the relationship between urban space and the people who live in it. The aim of LEUCHTTURM was to stop people in their tracks and encourage them to take a closer look at night-time Jena. At dusk visual coding was put in place on the top seven floors using 392 LED luminaires, which made the tracts of land around the building light up and become dark again. Each window was equipped with a single LED luminaire, which could be individually controlled, and a specially designed panel which reflected the light outwards and closed off the interior. The panels could simply be removed during the day as people were working in the building during the show. Innovative control systems from e:cue – a Lighting Application Suite Media Server and seven Butler S2 DMX512 interfaces with RDM capability – took care of the particularly demanding and pivotal job of providing lighting control.
