World’s first public net-surplus-energy building—it generates more energy than it consumes.

The new building of the first construction phase of the new town hall in Freiburg im Breisgau with its administration center and day nursery is the world’s first public building built to the net-surplusenergy standard and accommodates the 840 employees of the City Administration under one roof after they had previously been spread over 16 different sites throughout the city.
