Since opening the "Modern Wing" in 2009, the Art Institute of Chicago has become the second-largest art museum in the USA. The extension realized by HOCHTIEF subsidiary Turner increases the institution's space by one third. One of the highlights is the roof construction: It optically floats on high steel girders and triggers memories of a flying carpet. Its metal louvres can be adapted to outside conditions, with the ideal amount of light entering the building. The roof thereby protects the exhibits from direct sunlight and at the same time saves energy. The expansion was certified as green building and awarded the silver version of the LEED certificate.
