This is an interesting concept called the HyperGreen Tower by Jacques Ferrier, which was recently submitted to an architectural competition in Paris. The 246 meter tower design has an unusual curving exterior lattice facade made out of concrete that acts as the building’s primary structural system. This allows for adaptable floor plates and vegetated sky lobbies that sit between the tower’s facade and interior office space. The green highlights of the HyperGreen Tower include integrated solar cells, wind turbines, a rain water harvesting system and a geothermal heating system.
