The 2.3-million square-foot Pearl River Tower redefines what is possible in sustainable design by incorporating the latest green technology and engineering advancements. The 309-meter tower's sculpted body directs wind to a pair of openings at its mechanical floors, where traveling winds push turbines which generate energy for the building. The design for the tower incorporates a series of other integrated sustainable and engineering elements, including solar panels, double skin curtain wall, chilled ceiling system, under floor ventilation air, and daylight harvesting, all of which contribute to the building’s energy efficiency.
