The Council on Tall Buildings and Urban Habitat (CTBUH) is an international body in the field of tall buildings, including skyscrapers, and sustainable urban design. A non-profit organization{{cite web |title=Council releases list of Ten Tallest Building Projects for 2006 |url=http://www.ctbuh.org/LinkClick.aspx?fileticket=UgL4eFhGrEo%3d&tabid=1356&language=en-GB |publisher=Council on Tall Buildings and Urban Habits|archive-url=https://web.archive.org/web/20131012160808/http://www.ctbuh.org/LinkClick.aspx?fileticket=UgL4eFhGrEo%3D&tabid=1356&language=en-GB |archive-date=2013-10-12 |date=15 March 2006 |url-status=dead}} based at the Monroe Building in Chicago, Illinois, United States, the CTBUH announces the title of "The World's Tallest Building" and is widely considered to be an authority on the official height of tall buildings.{{cite news |url=http://www.cnn.com/2012/05/10/us/new-york-wtc-height/index.html |title=Design change could jeopardize WTC becoming nation's tallest building |work=CNN |access-date=11 May 2012}}{{cite news |url=https://blogs.wsj.com/metropolis/2012/04/30/one-wold-trade-center-why-new-yorks-tallest-doesnt-measure-up |title=Why New York's Tallest Doesn't Measure Up |work=The Wall Street Journal |access-date=1 May 2012 |first=Eliot |last=Brown |date=30 April 2012}}{{cite web |url=http://www.emirates247.com/property/real-estate/dubai-tops-residential-skyscrapers-2012-01-19-1.438569 |title=Dubai tops residential skyscrapers |access-date=30 April 2012}}{{cite web |url=http://www.chicagomag.com/Radar/Deal-Estate/December-2011/Whats-the-Hemispheres-Tallest-Residential-Building-Hint-Its-Not-Here/ |title=What's the Hemisphere's Tallest Residential Building?

The CTBUH was founded at Lehigh University in Bethlehem, Pennsylvania in 1969 by Lynn S. Beedle, where its office remained until October 2003 when it relocated to the Illinois Institute of Technology in Chicago.{{cite web |url=http://ctbuh.org/AboutCTBUH/History/tabid/112/language/en-US/Default.aspx |title=Council History |work=Council on Tall Buildings and Urban Habitat |access-date=2012-04-30 |archive-url=https://web.archive.org/web/20120504221338/http://www.ctbuh.org/AboutCTBUH/History/tabid/112/language/en-US/Default.aspx |archive-date=2012-05-04 |url-status=dead }}

Ranking tall buildings

The CTBUH ranks the height of buildings using three different methods:{{cite web |title=CTBUH Height Criteria |url=http://www.ctbuh.org/TallBuildings/HeightStatistics/Criteria/tabid/446/language/en-GB/Default.aspx |archive-url=https://web.archive.org/web/20101227114827/http://www.ctbuh.org/TallBuildings/HeightStatistics/Criteria/tabid/446/language/en-GB/Default.aspx |url-status=dead |archive-date=2010-12-27 |publisher=CTBUH |access-date=2014-08-24}}

Height to architectural top: This is the main criterion under which the CTBUH ranks the height of buildings. Heights are measured from the level of the lowest, significant, open-air, pedestrian entrance to the top of the building, inclusive of spires but excluding items such as flagpoles and antennae.
Highest occupied floor: Height to the floor level of the highest floor that is occupied by residents, workers or other building users on a consistent basis.
Height to tip: Height to the highest point of the building, including antennae, flagpoles, and technical equipment.

A category measuring to the top of the roof was removed from the ranking criteria in November 2009.{{cite news |url=http://www.ctbuh.org/NewsMedia/PR_091117_ChangeHeightCriteria/tabid/1273/language/en-US/Default.aspx |title=CTBUH changes height criteria, Burj Dubai height increases |date=17 November 2009 |publisher=Council on Tall Buildings and Urban Habitat |access-date=18 November 2009 |archive-url=https://web.archive.org/web/20180105123138/http://www.ctbuh.org/NewsMedia/PR_091117_ChangeHeightCriteria/tabid/1273/language/en-US/Default.aspx |archive-date=5 January 2018 |url-status=dead}} This is because flat-topped skyscrapers are not as common in the modern era, as skyscrapers with intricate spire designs and parapet features atop their roofs make it more difficult to define the roof of a building.

The CTBUH insist that a building should only be added to the official tallest list when it is (i) topped out structurally and architecturally, (ii) fully clad, and (iii) open for business, or at least partially open. This became the CTBUH official definition of a building's "completion".{{cite web |last=Gerometta |first=Marshall |title=Height: The History of Measuring Tall Buildings |url=http://www.ctbuh.org/AboutCTBUH/History/HistoryMeasuringTallBuildings/tabid/1320/language/en-GB/Default.aspx |publisher=Council on Tall Buildings and Urban Habitat |access-date=9 December 2011 |archive-url=https://web.archive.org/web/20110611040533/http://www.ctbuh.org/AboutCTBUH/History/HistoryMeasuringTallBuildings/tabid/1320/language/en-GB/Default.aspx |archive-date=11 June 2011 |url-status=dead}}

The CTBUH maintains an extensive database (named The Skyscraper Center) of the tallest buildings in the world, organized by various categories. Buildings under construction are also included, although not ranked until completion. The CTBUH also produces an annual list of the 10 tallest buildings completed in that particular year. Topping the 2008 list was the {{convert|492|m|ft|0|adj=on}} Shanghai World Financial Center in Shanghai, the then tallest building in the world according to the criteria of highest occupied floor, and home to the world's highest observation deck. Second on the 2008 list was the {{convert|363|m|ft|0|adj=on}} Almas Tower in Dubai, third was the Minsheng Bank Building in Wuhan which stands at {{convert|331|m|ft|0}}, whilst fourth was The Address Downtown Burj Dubai ({{convert|306|m|ft|0}}). All in all, six of the 10 tallest buildings completed in 2008 are located in Asia, three in the Middle East and one in North America.

Events

The CTBUH also hosts annual conferences and a World Congress every three to five years. The 2012 World Congress was held in Shanghai from September 19 to 21 .{{cite web |url=http://www.ctbuh.org/Default.aspx?alias=www.ctbuh.org/shanghai2012 |title=Asia Ascending: CTBUH 2012 World Congress |work=Council on Tall Buildings and Urban Habitat |access-date=18 May 2012 |archive-url=https://web.archive.org/web/20120507031457/http://www.ctbuh.org/Default.aspx?alias=www.ctbuh.org%2Fshanghai2012 |archive-date=7 May 2012 |url-status=dead }} The next World Congress was held in Chicago between October 28 and November 2, 2019.{{cite web|url=http://www.ctbuh2019.com |title=Shanghai 2014 |publisher=Ctbuh.org |access-date=2014-01-09}}

The CTBUH also bestows Tall Building Awards each year, with four regional awards to the Americas, Europe, Africa and the Middle East, and Asia and Australasia. Among these four regional awards, one is given the "Best Tall Building Award Overall." There are also two lifetime achievement awards. Starting in 2010, these awards are presented at a symposium and dinner held on the Illinois Institute of Technology's campus.{{cite web |url=http://www.ctbuh.org/Events/Conferences/Awards2011Symposium/tabid/2248/language/en-GB/Default.aspx |title=Awards 2011 Symposium |work=Council on Tall Buildings and Urban Habitat |access-date=18 May 2012 |archive-url=https://web.archive.org/web/20141006084809/http://www.ctbuh.org/Events/Conferences/Awards2011Symposium/tabid/2248/language/en-GB/Default.aspx |archive-date=6 October 2014 |url-status=dead }} In 2012, the CTBUH added two new awards for Innovation and Performance.{{cite web |url=http://www.ctbuh.org/Awards/Criteria/tabid/432/language/en-US/Default.aspx |title=CTBUH Awards Criteria |work=Council on Tall Buildings and Urban Habitat |access-date=18 May 2012 |archive-url=https://web.archive.org/web/20141006073352/http://www.ctbuh.org/Awards/Criteria/tabid/432/language/en-US/Default.aspx |archive-date=6 October 2014 |url-status=dead }}

Publications

In addition to the monthly newsletter and daily updated global news archive, the CTBUH publishes a quarterly CTBUH Journal. The Journal includes peer-reviewed technical papers, in-depth project case studies,{{cite web |url=http://www.ctbuh.org/Publications/Journal/CaseStudies/tabid/1090/language/en-GB/Default.aspx |title=CTBUH Journal Case Studies |work=Council on Tall Buildings and Urban Habitat |access-date=18 May 2012 |archive-url=https://web.archive.org/web/20141004133225/http://www.ctbuh.org/Publications/Journal/CaseStudies/tabid/1090/language/en-GB/Default.aspx |archive-date=4 October 2014 |url-status=dead }} book reviews,{{cite web |url=http://www.ctbuh.org/Publications/Journal/Reviews/tabid/1091/language/en-GB/Default.aspx |title=CTBUH Reviews |work=Council on Tall Buildings and Urban Habitat |access-date=18 May 2012 |archive-url=https://web.archive.org/web/20141004133758/http://www.ctbuh.org/Publications/Journal/Reviews/tabid/1091/language/en-GB/Default.aspx |archive-date=4 October 2014 |url-status=dead }} interviews with prominent persons in the tall building industry,{{cite web |url=http://www.ctbuh.org/Publications/Journal/Interviews/tabid/1541/language/en-GB/Default.aspx |title=CTBUH Interviews |work=Council on Tall Buildings and Urban Habitat |access-date=18 May 2012 |archive-url=https://web.archive.org/web/20141006100357/http://www.ctbuh.org/Publications/Journal/Interviews/tabid/1541/language/en-GB/Default.aspx |archive-date=6 October 2014 |url-status=dead}} and much more.

The CTBUH also publishes guidebooks, reference manuals, and monographs related to the tall building industry. In 2006 it published the book 101 of the World's Tallest Buildings in conjunction with author and CTBUH member Georges Binder, a reference to 101 of the world's tallest skyscrapers. It includes photos, plans, details on architects, engineers and stakeholders, and comprehensive technical data on each building. Since 2008 it has published a Best Tall Buildings book to accompany that year's awards.{{cite web |url=http://www.ctbuh.org/Awards/AwardsBook/tabid/849/language/en-US/Default.aspx |title=Awards Book |work=Council on Tall Buildings and Urban Habitat |access-date=18 May 2012 |archive-url=https://web.archive.org/web/20140214043223/http://www.ctbuh.org/Awards/AwardsBook/tabid/849/language/en-US/Default.aspx |archive-date=14 February 2014 |url-status=dead}}
