The Nanjing Student Center, located centrally in the master plan for the new Nanjing University in Xianlin, offers a singular expression of the dialogue between the idea of “big tent,” the collection of diverse constituents under one roof, and a tower which acts as a beacon and observation point.
The design exploits the techniques and economy of local construction practices as a means to develop an exceptional form. Poured-in-place concrete construction, using adjustable and recyclable form work, gives shape to a landscape-like roof that acts as the unifying “umbrella”.
The roof form is derived from a series of hyperbolic paraboloids, the ruling lines of which become reinforcing beams, all based on the same cross section, and distributed at regular intervals.
The interior accommodates a complex series of interrelated programs of student organizations and spaces for events. The spiraling form of the building is extended by a stair that ascends the outside of the tower. One of the two fire stairs is outside the body of the tower, thus allowing the unusually small floor plate that gives the tower its distinctive scale.
An economical and efficient passive energy strategy divides the building into several functionally independent zones, parts of the building that are not in use can be closed off thermally from those parts that are, dramatically reducing heating and cooling loads.
