Designed by Gensler and HDR, in association with Luis Vidal + Architects, the transformed Pittsburgh International Airport Terminal aims to create a more tranquil passenger experience while celebrating Western Pennsylvania’s identity. Completed in November, it is entirely powered by its own microgrid that uses natural gas and solar energy. A skybridge connects the new headhouse—which consolidates all major airport operations into a single structure—to a modernized terminal concourse. The roof, which consists of staggered peaks that frame clerestory windows, evokes the Allegheny Mountains, while branching columns recall trees. Augmenting the many nods to the region, the team included four verdant terraces featuring native plants, which are sustained by rainwater-harvesting systems.
