The number of skyscrapers completed in the year on the planet has stopped growing, but the momentum remains strong. In 2018, 143 towers of 200 meters or more have been delivered worldwide, according to the Council of Tall Buildings and Urban Habitat (CTBUH) annual report, located at the Illinois Institute of Technology in Chicago. . That is four fewer than in 2017. It is also the first decline after five years of continuous growth.
Not sure if this break is important: the number of great laps that are delivered every year was on average only 25 in the 2000s. In a world of rapid urbanization, the race remains buoyant, despite the energy-consuming model of these rounds giant, incompatible with the austerity advocated by climate policy.
Investors want even higher: 18 skyscrapers have exceeded 300 meters in 2018, a record. 16 buildings of the year participated with the top 100, only two less than the record of 2011. Last year, 19 cities in the world completed the highest tower of their skyline, including 14 in Asia. And the average height of towers of more than 200 meters completed in the year reached 247 meters, a rising figure remains.
A tower of 1,000 meters planned for 2021
There are now 1478 towers more than 200 meters worldwide, an increase of 141% compared to 2010, when the globe exhibited only 614 of such buildings. It is not surprising that Asia dominates the rankings, with 109 rounds delivered in the year, of which 88 in China, a record for the country, which for more than twenty years remains the area where the largest number of skyscrapers grows. The tallest building completed in 2018 is China Zun Tower in Beijing, whose concave profile rises to 528 meters. The building will be the fourth highest in China, the eighth in the world.
North America has completed 16 rounds of more than 200 meters in the year, including 8 in New York, which is similar to Beijing. Miami, San Francisco and Philadelphia increased their skylines in 2018. And 13 rounds were delivered in the Middle East, including 10 in Dubai. There are, finally, three tours in South America, one in Oceania and one in Europe: the Nurol Life Building … in Istanbul. Despite many projects and construction sites in London, in 2018 no tower of more than 200 meters has been delivered.
In Grand Paris it will take a few years before the Defense again appears on the ranking: the 244 meters of The Link (the future head office of Total) are expected in 2021, the Hékla and Sisters towers, signed respectively by Jean Nouvel and Christian de Portzamparc, will arrive in 2022, and the 320 meters of the hypothetical Hermitage Plaza Towers are announced for 2024.
Can the trend continue in 2019? In view of the projects already under way, the number of towers above 200 meters that was delivered this year, according to CTBUH, could reach the record of 150 skyscrapers, including 30 more than 300 meters. In the longer term, the risks of trade war and the tightening of economic policy in China could delay the construction of large towers. If the growing shortage of sand is required for the manufacture of concrete and glass, of which the skyscrapers are a hectic consumption.
Meanwhile, the Burj Khalifa in Dubai, delivered in 2010, still has the reputation of being the world's tallest skyscraper, at 828 meters. The Jeddah tower in Saudi Arabia, which is expected to reach 1,000 meters, is expected to be defeated in 2021.
