Tall buildings worldwide - statistics & facts
A skyscraper is defined as a very tall, continuously habitable building that generally has over 40 floors, but there is no universally defined minimum height. In the past, the word ‘skyscraper’ was also applied to buildings with just 10 stories. Today, skyscrapers may generally be defined based on their impact on the city’s skyline. Distinct from towers, many of these tall buildings tend to host offices, residential housing, and retail spaces. In the design and construction of skyscrapers, many factors must be considered including its ability to support its weight, resist wind and earthquakes, and its ability to protect its occupants against fire. With tall building design, the dead load (load of the structure) is larger than the live load (load from things within including people, furniture, etc.) and thus, there tends to be more structural materials used in the lower levels than in the higher levels.
The Burj Khalifa in Dubai is the tallest building in the world based on its height of 828 meters; it became the tallest tower in the world when it opened in 2010. It holds the record for the highest restaurant as well as one of the tallest observation decks in the world on the 124th floor. Despite its relatively small size, the United Arab Emirates is home to over 100 buildings that exceed 200 meters. However, the vast majority of skyscrapers are located in Asia, with China being home to over 680 tall buildings, followed by the United States at over 200 buildings.
In the United States, the Willis Tower in Chicago is considered the largest building in the country based on number of floors, although the One World Trade Center in New York City is considered the largest based on height. The One World Trade Center is largely owned by the Port Authority of New York and New Jersey and can boast the One World Commons, a space full of amenities for the tenants including conference rooms, a game room, and a café.
