The Chicago Central Area DeCarbonization Plan in Chicago, Illinois. Designed by Adrian Smith + Gordon Gill Architecture. Winner of the 2011 Institute Honor Award for Regional and Urban Design. Project description: "The project team developed a database (energy use, size, age, use, and estimated carbon footprint) of more than 550 buildings. The team used that database, tied to a 3-D model, to develop the DeCarbonization Plan, which interweaves energy engineering, architecture and urban design. In the DeCarbonization Plan's synergistic approach, eight key strategies work together with a parametric model."
