Built in World War II, the Energy Bunker is a former anti aircraft structure. During the war, it also offered shelter for thousands of refugees. The bunker was damaged and run down in the aftermath of the war and as a ruin it was not touched for almost sixty years.
With the IBA Building Exhibition coming up in 2013 it was completely renovated and refurbished into a sustainable energy plant. With its impressive solar power installations on the roof and on the south side it produces heat and power respectively. It also has a biomass and -gas installation inside. With the electricity, approximately 1000 households are served. The heat is stored into a 2.000.000 liter water tank at the heart of the bunker. Heat from a nearby industrial power plant is also stored therein. Together, the heat capacity is enough for approximately 3000 households.
As a symbol of the energy transition of Germany, the local neighborhood Wilhelmsburg is proud of the sustainable energy plant. Also it is a war memorial. And it functions as a social place, as a 30 meters high terrace with a trendy coffee bar attracts many local.
