NATURALLY COOL CONVENTION CENTER

Echoing the shape of bridges arcing over the Allegheny River in Pittsburgh, Pennsylvania is the new David L. Lawrence Convention Center. A sail-like roof is suspended from steel cables over the four-story riverfront building.

The dramatic form designed by architect Rafael Viñoly Architects is more than visually striking, however. The sweeping roof channnels river breezes and creates a degree of natural ventilation that is extraordinary for a building of this type and size.
