Council on Tall Buildings and Urban Habitat. The Council on Tall Buildings and Urban Habitat is an international nonprofit organization headquartered in Chicago, serving as the world’s leading authority on the planning, design, construction, and operation of skyscrapers and future megacities. Founded in 1969 at Lehigh University in Pennsylvania, it convenes a multidisciplinary network of professionals from fields including architecture, structural engineering, urban planning, and construction. The organization is best known for establishing the definitive global standards for measuring building height and for maintaining the authoritative database of the world’s tallest structures.

History

The organization was established in 1969 at Lehigh University in Bethlehem, Pennsylvania, following a seminal conference on tall buildings funded by the National Science Foundation. Early leadership included figures like Lynn S. Beedle, who directed the organization for decades and helped establish its global reputation. Initially focused on structural engineering research, its scope expanded significantly under the guidance of leaders such as David Scott and later Antony Wood. In 2003, its headquarters relocated from Lehigh University to the Illinois Institute of Technology in Chicago, and later to its own offices in the Monadnock Building in the city's Loop district, cementing its connection to a major global hub of skyscraper development.

Mission and activities

The core mission is to disseminate multidisciplinary knowledge on tall buildings and sustainable urban habitats to improve the urban environment globally. Key activities include hosting major international conferences, such as the annual CTBUH International Conference, held in cities like Shanghai, Dubai, and Sydney. It facilitates extensive research projects and technical working groups on topics ranging from seismic design to wind engineering and vertical transportation. The organization also acts as a crucial mediator and advisor on tall building projects worldwide, providing expertise to developers, architects like Skidmore, Owings & Merrill, and city governments from Singapore to London.

Height criteria and definitions

The organization is the ultimate arbiter for officially ranking the world’s tallest buildings, maintaining rigorous and publicly documented criteria. Its standards define multiple height categories, with the primary one being "height to architectural top," which includes spires but excludes antennas and flagpoles. These criteria have been applied to adjudicate records for iconic structures such as the Burj Khalifa in Dubai, the Shanghai Tower, and the Merdeka 118 in Kuala Lumpur. The definitions are periodically reviewed by its Height Committee, comprising experts from firms like Gensler and Arup Group, to address evolving design features like occupied pinnacles and supertall mixed-use developments.

Awards and recognition

The organization presents several prestigious annual awards that are highly coveted within the AEC industry. The most prominent is the "Best Tall Building Worldwide" award, with past winners including the Bosco Verticale in Milan and the Vancouver House in Canada. Other accolades include the "Innovation Award," "10 Year Award" for proven performance, and the "Lifetime Achievement Award," which has honored influential individuals such as architect César Pelli and engineer Fazlur Rahman Khan. These awards are typically presented at a gala ceremony during the annual conference, offering significant international recognition to projects and professionals.

Publications and resources

It produces a wide array of authoritative publications, most notably the quarterly "CTBUH Journal," which features peer-reviewed research papers and case studies. The organization also publishes detailed reference books, technical guides, and the annual "Tall Building Yearbook." Its most utilized public resource is the comprehensive "Skyscraper Center" online database, an interactive portal cataloging thousands of tall buildings globally. Additional resources include research reports on specific topics like carbon footprint and facade engineering, often produced in collaboration with academic partners like Tongji University or industry leaders like Kohn Pedersen Fox.

Governance and organization

Governance is overseen by a Board of Trustees, which includes senior executives from major firms such as AECOM, Samsung C&T, and Hyundai Engineering & Construction. Day-to-day operations are led by an Executive Director, a role held since 2006 by Antony Wood, who is also a professor at the Illinois Institute of Technology. The organization is structured into various committees, including the aforementioned Height Committee and Research Committee, and maintains a global presence through chapters in key regions like Asia, the Middle East, and Europe. Funding is derived from membership dues, conference revenues, and sponsorships from corporations like Otis Elevator Company and ThyssenKrupp.
