Volker Finke
In 1993, Rolf Disch Solar Architecture and coach Volker Finke created the initiative to change their field into a solar stadium. Photovoltaic panels were installed on the roof, creating the first solar powered stadium. The stadium was eventually outfitted with floodlights after Freiburg was promoted to the 1. Bundesliga. The stands to the east of the pitch received a roof and 1,580 new seats. The number of seats in main stands was increased to 5,000.
