How do we determine the actual height of a building? Where do we place the dimension line? The history of measuring skyscrapers dates back to 1885, way before AutoCAD or Revit dimensions, when the Home Insurance Building in Chicago was among the first to boast of being the world's tallest building, but the Council on Tall Buildings and Urban Habitat (CTBUH)—or the Joint Committee on Tall Buildings, as it was originally called—wasn’t formed until 1969. Recognized by many as the foremost authority on tall buildings, the CTBUH is often cited in determining the world’s (or country’s or city’s) tallest building. However, the CTBUH is not the only organization with a stake in measuring buildings; the global building information database Emporis is also a major player. Between them, these two organizations provide 10 different ways to determine a skyscraper's height, which we have summarized below.
KPF’s Lotte World Tower in Seoul, South Korea is officially complete, according to criteria established by the the Council on Tall Buildings and Urban Habitat (CTBUH). At 555 meters tall, the building becomes the tallest building in Korea (250 meters taller than the previous tallest building, Northeast Asia Trade Tower) and the world’s new 5th tallest building.
Have you been experiencing motion sickness, depression, sleepiness, and even fear, as you gaze out of your window from the 44th floor? If so, you may be prone to “Sick Building Syndrome” – the informal term for side effects caused by swaying skyscrapers, according to experts at the Universities of Bath and Exeter, who are launching a £7 million ($8.6 million) study into their causes and prevention through testing simulations.
“More and more people are living and working in high-rises and office blocks, but the true impact of vibrations on them is currently very poorly understood,” explained Alex Pavic, Professor of Vibration Engineering at the University of Exeter. “It will for the first time link structural motion, environmental conditions, and human body motion, psychology, and physiology in a fully controllable virtual environment.”
The Council on Tall Buildings and Urban Habitat (CTBUH) has announced the completion of the Ping An Finance Center in Shenzhen, China, according to CTBUH tall building criteria. At 599 meters (1965 feet), it is now officially the second tallest building in China and the fourth tallest in the world, behind only the Burj Khalifa, Shanghai Tower and Makkah Royal Clock Tower.
Designed by Kohn Pedersen Fox Associates (KPF), the Ping An Finance Center is located in the heart of Shenzhen’s Fuitan District. The building contains over 100 floors of office space located above a large public podium, with a multi-story atrium providing retail, restaurants and transit options to the city and greater Pearl River delta region.
In its annual report, the 2016 Tall Building Year in Review, the Council on Tall Buildings and Urban Habitat (CTBUH) has announced that 2016 saw the completion of a record 128 buildings 200 meters or higher. This number surpasses the previous record of 114 completions set in 2015. Eighteen of these buildings became the tallest in their city, country, or region, and ten earned the designation of supertall, at 300 meters and above.
The Council on Tall Buildings and Urban Habitat (CTBUH) has named Gensler’s Shanghai Tower as the 2016 Best Tall Building Worldwide, citing its “innovative design scheme in traditional Shanghainese architectural traditions.” The building was selected from among four regional winners, which included BIG’s VIA 57 West (Americas), Jean Nouvel’s The White Walls (Europe) and Orange Architects’ The Cube (Africa).
The Council on Tall Buildings and Urban Habitat (CTBUH) has released some of the facts and figures behind the projects appearing in their recent book, 100 of the World’s Tallest Buildings. The construction of tall buildings requires collaboration between many different companies and firms and the efforts of hundreds of people, but a few select firms have been responsible for more of the design and engineering achievements than any other.
Continue reading to see the 18 design architects that have contributed multiple buildings to the top 100 list.
The past ten years have seen a new twist in tall building design: buildings that rotate as they rise, either for engineering or purely aesthetic purposes. Inspired by this recent trend, the Council on Tall Buildings and Urban Habitat (CTBUH) has produced a new graphic entitled Tall Buildings in Numbers “Twisting Tall Buildings” to analyze the “recent proliferation of twisting towers creating a new generation of iconic buildings throughout the world.”
The infographic compares the buildings by height, along with the tightness and total degrees of their rotation. Continue after the break for the full graphic and links to the projects on ArchDaily.
When it comes to skyscraper architects, the first name that comes to mind is often Skidmore, Owings & Merrill. No firm has completed more supertall buildings than SOM, and to this day, they remain a leader in the field, designing both the western hemisphere’s and the world’s tallest buildings in One World Trade Center and the Burj Khalifa. Yet, arguably, the height of their powers came in the 1970s, directly following a lull in skyscraper construction that allowed the Empire State Building to retain the status of world’s tallest building for nearly 40 years.
It was then that Falzur Khan, a SOM architect and structural engineer, came up with the structural innovation that revolutionized the skyscraper industry, leaving lasting impacts on the construction methods of supertall buildings today.
Drawing from a recent story published by Mental Floss on the designer, we’ve come up with a list of facts about his life and role in the world of architecture.

In an interview with the Council on Tall Buildings and Urban Habitat (CTBUH), Bjarke Ingels reflects on the design of skyscrapers, noting how "sculpture is fine, but if its arbitrary it's not as interesting." Architects, Ingels argues, have the problem of "skilled incompetence:" the notion that they "already know the answer before [they've] even heard the question." This prevents them "from questioning the question, or having the question rephrased, or elaborating on the question, or even listening for the question – because [they] already know the answer."
The Council on Tall Buildings and Urban Habitat (CTBUH) is pleased to announce its 5th International Student Tall Building Design Competition. The goal of the competition is to shed new light on the meaning and value of tall buildings in modern society.
As worldwide populations continue to urbanize and grow, creating megacities, the role of the tall building in the twenty-first century has moved beyond simply addressing spatial and economic efficiencies. The permanence of these structures necessitates careful forethought into how they will interface with the surrounding urban context, the natural environment, their inhabitants, and the world as a whole. Although they are statically embedded in our cities, skyscrapers must employ a dynamic spatial and functional dialogue, allowing them to remain active and relevant for not just decades, but centuries.
The China International Exchange Committee for Tall Buildings (CITAB) and the Council on Tall Buildings and Urban Habitat (CTBUH) have announced the winners of their inaugural China Tall Building Awards. Four buildings, including two designed by Zaha Hadid and Kengo Kuma, were chosen as China's best tall buildings. Other winners were recognized for their innovation, success within the urban environment, and construction excellence.
"With the support of the Architectural Society of China and the Architectural Society of China Shanghai, the first year of this regionally focused awards program was very successful, with numerous high-quality projects entering into the running under six categories of recognition," said CITAB and CTBUH.
Following the recent completion of 432 Park Avenue in New York City, The Council on Tall Buildings and Urban Habitat (CTBUH) has announced that there are now 100 supertall (300-plus-meter) skyscrapers in the world. The majority of these skyscrapers are in Asia and the Middle East, mirroring construction trends that have emerged over the past decade. Dubai leads the rankings with 18 supertall buildings, while New York City now falls in second place with a total of seven, including 432 Park Avenue.
Gensler's recently completed Shanghai Tower is now the 2nd tallest building in the world, and the tallest building in China, according to The Council on Tall Buildings and Urban Habitat (CTBUH). At 632 meters tall, it is the third building in the world to exceed 600 meters and be designated “megatall.”
