The Council on Tall Building and Urban Habitat have announced the winners of the 16th edition of the CTBUH Tall Building Awards. From over 48 finalists in 28 countries, the best buildings from four regions – the Americas, Asia & Australasia, Europe, and Middle East & Africa – were selected, along with recipients of the Urban Habitat Award, the Innovation Award, the Construction Award and the 10 Year Award. From these finalists, the CTBUH has also awarded the Best Tall Building Worldwide to the Oasia Hotel Downtown by WOHA.

The towers were chosen by a panel of architects from world-renowned firms and were judged on every aspect of performance, looking in particular for those which “have made extraordinary contributions to the advancement of tall buildings and the urban environment, and that achieve sustainability at the highest and broadest level.”

The Council on Tall Buildings and Urban Habitat (CTBUH) has recently released a new research study titled "Tallest Demolished Buildings" that examines 100 of the tallest buildings ever to have been dismantled by their owners. The report confirms that, if JPMorgan Chase continues with their plans, SOM's 270 Park Avenue in New York City would become the tallest building ever conventionally demolished, as well as the first over 200 meters in height.

The study showed that in most cases, the buildings were torn down to make way for newer high-rises, as was the case for the current tallest building ever to be demolished, the Singer Building in New York City. The Singer Building stood 187 meters and 41 stories tall until it was torn down in 1968 to make way for One Liberty Plaza.

We all know a little about the world's tallest buildings—those engineering feats which define their cities and become symbols of human achievement—but what of the buildings that never took their planned place in their respective skylines? In 2014, The Council on Tall Buildings and Urban Habitat (CTBUH) released a report listing the 20 tallest buildings that were never completed (an up-to-date list is also maintained on their website here). In order to be considered "never completed," all of the buildings in the report had begun site work, but construction was completely halted with no reports indicating it will continue. Read on to find out the top 10 tallest uncompleted buildings in 2018 after the break.

2017 was another banner year for skyscraper construction.

According to the 2017 Tall Building Year in Review, the annual web report from The Council on Tall Buildings and Urban Habitat (CTBUH), a record-breaking 144 buildings 200 meters tall (656 feet tall) or higher were completed in 2017, led by the 599-meter-tall Ping An Finance Center and 555-meter-tall Lotte World Tower.

In the report, CTBUH outlines this year’s trends in tall building design. Notably, 2017 proved to be the most geographically diverse year in history for tall buildings, with 69 cities across 23 countries completing new towers, an significant increase from 54 cities and 18 countries in 2016. Of those numbers, 28 cities and 8 countries completed their new tallest building.

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.

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 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.

Bjarke Ingels on Sculptural Skyscrapers and Refining Parameters in High Rise Design

07:30 - 18 April, 2016

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."
