Hutton’s sustainable design for BSU building wins first prize
Published: 22-Feb-2010
German architectural design practice Sauerbruch Hutton has won the first prize in an international competition to design a new home for Behorde fur Stadtentwicklung und Umwelt (BSU) or The Hamburg Ministry of Urban Development and Environment, in Germany.
The new BSU building consists of one high rise and two wing buildings. The street level floors are designed to house public BSU facilities such as areas for exhibitions and restaurants. The foot of the high rise structure accommodates a central lobby. It is conceived as an amphitheater, envisioned to host the exhibition of Hamburg’s urban model. The space will be visible through the large glass facade. The library and conference center can also be accessed from there.
The building is structured in seven separate ‘houses’, which are linked through a natural light-lit access road. Each house features an open staircase atrium. The atrium is designed to offer easy orientation, efficient vertical access, good distribution of natural light into interior spaces, and natural cross-ventilation.
One of the key objectives of the design was to reduce the building’s energy consumption by combining passive and active measures. The compact building volume uses renewable resources like natural lighting, natural cross-ventilation, and sun-powered heating. Energy harvested from geothermal and solar equipment is combined with a gas-powered heat and power unit. The design also ensures reasonable transparency, and protection from intense sunlight in the facades.
The new BSU building is slated for completion in 2013.
