The sweeping roof of Rafael Vi'oly's David L. Lawrence Convention Center (below) echoes Pittsburgh's 'Three Sisters' bridges. When it opened in 2003, the LEED Gold, 1.5 million-square-foot facility was the world's largest green building. Earlier this year, the convention center earned a Platinum rating for its operations and maintenance practices as part of the LEED-EBOM program, making it the first convention center with certification for both new construction and existing buildings. In 2011, a waterfront plaza in front of the building (bottom) was completed, extending an existing shoreline trail for pedestrians and cyclists. The park, designed by LaQuatra Bonci Associates, also provides recreational boat access.
