Shanghai IFC is one of the most significant new developments in the Pudong New Area, China’s most important financial and commercial center. It consists of three mixed use towers, a shopping mall and a public plaza which acts as the central element of Pudong’s skyline. It joins landmarks like the Oriental Pearl Tower, and enjoys a view of the Bund, Shanghai’s historic riverfront promenade. The development is home to a multitude of international businesses, symbolizing China’s remarkable commercial growth.
The towers share a common architectural language. Starting with elegant, rectilinear forms clad in a vertically-grained glass-and-steel curtain wall, the design team sculpted the towers by slicing off corners and edges, creating crystal-like towers that gesture toward one another, and producing a single composition from two buildings. Where the towers are sliced away, a horizontally-grained interior is revealed, adding visual richness to the soaring forms. The two angled towers also respond to their varied urban surroundings—low-rise residential buildings to the south, a major roadway to the north, tall towers to the east, and new hotels and retail developments to the west.
A four-level podium houses approximately 55,000 square meters of retail, restaurants and support spaces for the hotels. Pedestrian connections to the adjoining sites are conveniently provided by tunnels and sky bridges.
ALT was able to develop the façade system by adopting a fully-unitized rain screen system for towers 1 and 2, with a vertical fin of 75mm depth attached in every mullion. Both towers are made up of double glazed glass with low-e coating. Furthermore, the hotel façade is made up of a fully unitized system with a combination of stone cladding.
ALT considers the lighting behind the spandrel glass as one of its unique façade features as it creates a uniform translucent effect wrapping the entire building.
ALT shares that one of the major façade challenges they encountered for Shanghai IFC is the integration of lighting fixtures inside the façade system. Installation of lighting features go hand-in-hand with maintenance and heat build-up problems. This is why ALT designed the façade system in such a way that it allows maintenance access from the inside to avoid heat built-up inside the spandrel area. One example of this is the usage of Low voltage LED lights.
