Founded in 1969 and headquartered in Chicago at the Illinois Institute of Technology, the Council on Tall Buildings and Urban Habitat is an international non-profit organization whose membership includes architects, engineers, planners, construction professionals, and educators from 77 countries. It was established to facilitate professional exchanges among those involved in the planning, design, construction and operation of tall buildings and the urban habitat. Its primary goal is to promote better urban environments by maximizing the international interaction of professionals, and by making the latest knowledge available to its members and to the public at large. The Council is the official source for the 100 Tallest Buildings in the World.
