The main structure system is the combination of the mixed structure system which utilizes concrete-filled tubular column together with steel beams, and the concrete core. The whole building is supported both vertically and horizontally from the concrete core with the steel structure beams inside. Combining the horizontal frames and vertical frames, a lantern shaped structure system not only can fulfill the structure requirement for earthquake and self load bearing, but also creates the sunrise profile of the building.
Within the same floor area, ellipse floor plate building can get extra 25% daylight comparing with normal single tower building. Four-layered Low-E glazing system is used in order to achieve both the lightness as well as decent indoor thermal comfort. The ventilation pipes, being installed inside the vertical bars on the facade, can conduct the fresh air through the perforated aluminum panels. The building has CCHP system that uses natural gas as the main energy source to provide power. The system can recycle the waste heat for hot water and pre-heat the air through heat exchanger, pushing the efficiency to 90%. It also replaces the air conditioner in summer to lower the power demands from the grid system.
