The BIX light and media facade consumes as much energy as an average single-family house in a year. In the future, however, it will only illuminate the night if there were enough hours of sunshine in Graz during the day. This concept of media artist Onur Sönmez for the BIX project Sunscriber ensures that the energy required for the BIX light and media facade is generated by means of a photovoltaic system on the roof of the Needle. This way, nature will determine whether and how long the BIX lights up at night. This approach is Sönmez’ answer to the requirements for the mitigation of climate change and to the lower energy consumption needed to achieve this. In general, the project is a critical statement on energy generation and the naturalness of light in urban space. It is implemented with the help of Jona Hoier and Mehmet Ekinci. The project ties in perfectly with the ecology-focused sectionof the exhibition what will be, a part of SHOWING STYRIA in the Kunsthaus Graz primarily themed around the future of Styria.
