According to CTBUH, there are now 100 supertall skyscrapers in the world.
Following the completion of 432 Park Avenue in New York City this week, the Council on Tall Buildings and Urban Habitat (CTBUH) reported that the world now has 100 supertall (300-meter) skyscrapers. The construction of supertall buildings has increased at an alarming pace in recent years, indicating the global tall building industry's tremendous development. Whereas the first 50 supertalls took 80 years to construct (between 1930 and 2010), the total number of supertalls has doubled in just five years, from 50 to 100. apartment for sale in qatar
While Asia and the Middle East have
generated the majority of new supertall skyscrapers, New York has remained an
important center for supertall construction in the Americas. With this, the
city's seventh, supertall skyscraper, New York now has the world's
second-highest number of supertall skyscrapers. Meanwhile, Dubai maintains its
lead in the rankings, with 18 points.
The CTBUH announced that 432 Park Avenue
was completed on December 23, 2015, since that was when the first owners closed
on their homes and the building met CTBUH's final completion requirements,
which required that it be at least partially occupied. It is the world's
tallest all-residential building, standing at 425.5 meters, and the 14th
tallest overall. It stands out not only for its extreme height, but also for
its slenderness. The tower typifies the "superslim" typology made
possible by developments in lateral resistance technology, with a
1:15slenderness ratio. These structures are especially common in densely
populated areas like New York, where limited land supply and skyrocketing
luxury residential prices justify their construction.
In the coming years, supertall construction
is expected to develop. According to CTBUH info, there are more than 100
supertall skyscrapers that have been completed or are in the process of being
completed in the next five to six years. That includes Jeddah Tower, which,
when completed, will be the world's tallest building and the first
kilometer-high structure.
With supertall skyscrapers becoming more
popular, many see megatall buildings (600 meters or more) as the next frontier
for the world's tallest structures. Only three megatall buildings have been
built around the world, but that number is expected to more than double in the
coming years as four more, including Jeddah Tower, are completed.
Shanghai Tower is the world's newest mega
skyscraper.
The Council on Tall Buildings and Urban
Habitat (CTBUH) has designated Shanghai Tower as the world's second-tallest
building, following its completion in China. The tower was completed in late
2015 and stands at a height of 632 meters, making it the world's third
"megatall" (600-meter-plus) structure.
Shanghai Tower's completion is noteworthy
in that it knocked Chicago's 442-meter Willis Tower (originally Sears Tower),
once the world's tallest building, out of the Top 10 list for the first time
since its 1974 completion. Willis Tower was among the Top 10 Tallest Buildings
for 41 years before being surpassed by skyscrapers mainly built in Asia and the
Middle East. Given the rapid growth of urban centers in these regions and the
new heights that contemporary tall buildings are achieving, CTBUH data predicts
that Willis Tower will be out of the Top 20 Tallest Buildings in less than five
years.
Shanghai Tower, the third of a trio of signature
skyscrapers in Shanghai's Lujiazui Finance and Trade Zone, represents a new
model for tall buildings. The new tower rises high above the skyline, its
curved façade and spiraling shape symbolizing the dynamic emergence of modern
China. It is located near Jin Mao Tower and Shanghai World Financial Center. As
compared to a rectangular building of the same height, its twisting shape saves
24 percent in structural wind loading, according to wind tunnel studies. The
software of the tower is unusual in that it is divided into nine vertical
zones. Each of these "vertical communities" is built around a sky
lobby, a light-filled garden atrium that fosters a sense of community and
provides tenants and visitors with a diverse program.
