武汉绿地中心项目规划设计方案英文版

　　Wuhan Greenland Center features a uniquely streamlined form that combines three key shaping concepts—a

　　tapered body, softly rounded corners and a domed top—to reduce wind resistance and vortex action that builds up

　　around supertall towers. The building’s extremely effi cient aerodynamic performance will allow it to minimize the

　　amount of structural material (and its associated embodied carbon) needed for construction.

　　The tower’s three corners rise from its tripod-shaped base and taper upward, culminating in an arched tip above the

　　dome at the top. The corners will be of smooth curved glass, contrasting markedly with the more textured curtain

　　wall cladding the body of the tower. The curtain wall, still under design, will enclose a composite concrete core with

　　steel framing. Apertures in the curtain wall at regular intervals will assist in venting wind pressure against the tower;

　　the apertures will also house window-washing systems and air intake and exhaust systems on mechanical fl oors.
