To live up to the intention of offering more activities between the workshops, HEEN organised a tour at EUREF Campus in Berlin, followed by a Stammtisch in a nearby bar in early August 2017. The EUREF Campus was built around the symbolic gasometer located in Schöneberg. The area is today an open-air laboratory that houses start-ups, multinationals, think-tanks, research centers and other stakeholders developing new technologies and business models related to clean energy, mobility and IoT. The campus has a mini-grid powered by all renewable energy sources and met the climate targets for 2050 already in 2014.
