Gordon Gill, FAIA, is one of the world’s foremost exponents of performance-based architecture. His work, which ranges from the world’s largest buildings to sustainable communities, is driven by his philosophy that there is a purposeful relationship between formal design and performance; and that there is a language of performance, which is the basis of his practice: Form Follows Performance. Gordon is a founding partner of Adrian Smith + Gordon Gill Architecture, which is defining buildings and cities of the future around the globe from their studio in Chicago. While he was an Associate Partner at SOM, Gordon was responsible for the Pearl River Tower in Guangzhou, China, designed as the world’s first net-zero-energy skyscraper. Since then his work includes the world’s first large-scale energy-positive building, the world’s tallest tower, as well as the Astana Expo 2017 and its sustainable legacy community. Gordon's designs share a keen awareness of local environmental conditions as they capitalize on physical and environmental features to maximize building performance. These ecological strategies are legible in his projects’ architectural vocabulary.
