Dreisamstadion (or badenova-Stadion) is a multi-purpose stadium in Freiburg, Germany. It is currently used mostly for football matches and is the home stadium of Sport-Club Freiburg. The stadium holds 24,000 spectators and was built in 1953. Due to a sponsorship deal, it is currently named the badenova-Stadion.
In 1993, Rolf Disch Solar Architecture and coach Volker Finke created the initiative to change their field into a solar soccer stadium. Photovoltaic panels were installed on the roof and SC Freiburg was the first soccer team in Germany with solar power. This ecological step reinforced Freiburg's image as the "Solar City" and demonstrated the need for renewable and sustainable energy in all locations and venues.
