A skyscraper, also known as a high-rise, is a continuously habitable high-rise building that has over 40 floors and is taller than 150 meters (492 feet). The term “skyscraper” was first used in the late 19th century to describe the tall buildings being constructed in Chicago, United States. Today, skyscrapers are found in cities all over the world and are used for a variety of purposes, including offices, residential units, and hotels.
Skyscrapers have a number of advantages over other types of buildings. They can accommodate a large number of people in a relatively small area, which can be important in densely populated cities. They can also be designed to be energy-efficient and environmentally friendly. In addition, skyscrapers can be iconic landmarks that define a city’s skyline.
The construction of skyscrapers has been made possible by a number of technological advances, including the development of steel-framed construction, elevators, and fireproofing materials. The first skyscraper was the Home Insurance Building in Chicago, which was completed in 1885 and had 10 stories. Since then, skyscrapers have become increasingly taller and more complex. The current tallest building in the world is the Burj Khalifa in Dubai, which has 163 stories and is 828 meters (2,717 feet) tall.
1. Height
Height is a defining characteristic of skyscrapers, and is a major factor in determining their classification as such. The Council on Tall Buildings and Urban Habitat (CTBUH) defines a skyscraper as a building with at least 50 stories or a height of 200 meters (656 feet). However, the term “skyscraper” is often used more broadly to refer to any very tall building, regardless of its exact height.
There are several reasons why height is important for skyscrapers. First, height allows skyscrapers to accommodate a large number of people and businesses in a relatively small area. This is important in densely populated urban areas, where land is scarce and expensive. Second, height can be used to create iconic landmarks that define a city’s skyline. Third, height can be used to improve the energy efficiency of a building.
