The aerodynamically designed high-rise building which houses the offices of the Deutsche Post is a remarkable example of the collaboration between Helmut Jahn, Werner Sobek and Mathias Schuler. This innovative design has in the Urban Land Institute.
The plan consists of two half oval towers, which are shifted slightly towards each other, enclosing a central winter garden which optimises energy consumption. The offices can be naturally ventilated for a large part of the exhaust air ventilating the winter garden. The integrated, computer-controlled heating and cooling system balances the inside and outside temperatures perfectly, and the use of innovative double skin façades make this building an example of state-of-the-art façade technology. This book portrays this structure in stunning duotone photographs, short texts and plans.
