Info

The new office building for the building and environment authorities (BSU) provides several public areas next to office space for approximately 1400 employees. This includes an exhibition area, a restaurant, the traffic department, the building permit department and a library. The accessibility to the building to the public and the creation of informal meeting points are the central guiding idea of the draft. All offices are naturally ventilated and have the same room qualities. Through exceptionally low primary energy demand (72% below EnEV 2007) the building obtains an excellent carbon footprint of only 18,9 kg CO2/m²a. Furthermore, through the use of ecological and recyclable building materials and the consideration of other aspects the building aims for the Gold certificate from the German Sustainable Building Council (DGNB).
