Each tower carries its own cable-stay bridge forming a passageway between the two towers. The bridges meet at an angle, joining like a handshake over the harbour according to the architect, Steven Holl Architects. The towers will mostly be offices with some public spaces.
"With the winning project, we get a great high-rise building, which will bind the city better together and function as a landmark in the harbour," said the current mayor of Copenhagen, Ritt Bjerregaard.
The project utilizes a variety of sustainable technologies. Both towers have glazed facades which are shaded by solar screen made of photovoltaics. The towers are connected to a seawater heating/cooling system which provides radiant heating in the floor slabs and radiant cooling in the ceiling. Natural ventilation is provided by windows opening at the floor level and ceiling level for maximum air circulation. Wind turbines are lined up along the top of the pedestrian bridge roof, which will provide enough electricity for lighting all the public spaces.
