Steel and Skyscrapers: A Brief History

The history of skyscrapers dates back to the second half of the 19th century when steel became a cornerstone of the world’s industrial economy. Steel framing and steel reinforced concrete made “curtain-wall” architecture possible, which led to the world’s first skyscrapers. Steel further evolved the capabilities of skyscrapers, allowing them to reach new heights. From the humble beginnings of the first skyscraper, the Home Insurance Building, built in Chicago in 1895 and standing 42m, skyscrapers now reach extraordinary heights.

Here are the four tallest skyscrapers in four of the regions of the world today. 

Burj Khalifa, Dubai, Middle East

Rising to 829.8m over the gulf city of Dubai, the Burj Khalifa is the tallest building in the world. Designed by Skidmore Owings and Merill (SOM), the Burj Khalifa used a bundled tube design and a composite of steel and concrete to reach its record height. The Burj Khalifa employed a bundled tube system which is a system of construction that uses an interconnected frame of steel tubes. Thirty-nine thousand tons of steel rebar was needed for the construction. The Burj Khalifa houses a mix of residential, corporate and retail space.

Shanghai Tower, Shanghai, Asia

Standing 632m, the 128-story Shanghai Tower is located in Shanghai’s financial district of Lujiazui, Pudong in China. Though currently still under construction, following its topping out in 2013, the Shanghai Tower is the tallest building in China and the second-tallest building in the world, surpassed only by the Burj Khalifa in Dubai. The Shanghai Tower is the tallest of a group of three adjacent supertall buildings in Pudong and is composed of three important design strategies, the asymmetry of the tower’s shape, its tapering profile and its rounded corners, all of which will allow it to withstand typhoon wind forces common in Shanghai. 

One World Trade Center, New York, North America

Designed by the same firm that designed the Burj Khalifa, the 104-story One World Trade Center reaches a height of 417m. Including the spire, its total height is 541m (1,776 ft.), a tribute to 1776, the year the U.S. won its independence. Surpassing the Willis Tower (formerly Sear’s Tower) in Chicago, the One World Trade Center is the tallest building in the U.S. The tower’s structure is designed around a strong, but lightweight, steel frame made of beams and columns. The lighter structures enabled savings in greenhouse gases and a 30 percent decrease in carbon emissions during construction. There are 70 elevators and nine escalators in the One World Trade Center. (Image: http://bit.ly/1DsqmBK)

The Shard, London, European Union

The Shard is a 72-story glass pyramid tower, rising above the city of London. It was completed in 2012, and stands 245m. The design uses an intelligent combination of steel and concrete. Steel structures were used from the ground floor to the 40th floor. From there to the 69th floor, concrete replaces the framing material, before the design reverts back to steel. Construction required 12,000 tons of steel.

As the world continues to grow and urbanize the ability to adapt building structures and materials will continue to evolve. Steel will continue to be essential in helping the world’s buildings reach new heights.

Both individuals and corporations must become more environmentally responsible, being mindful of the levels of waste water, trash and emissions produced both at home and in the office. Considering these factors in the architectural designs of the future, we can ensure a healthy and sustainable planet. Yet, a number of buildings are a step ahead and have already incorporated sustainability into their own designs, setting the precedent for future architectural endeavors. On this World Environment Day, let’s take a look at a few of them.

Northeast Asia Trade Tower (NEATT)

Standing 68 stories tall, the Northeast Asia Trade Tower in Songdo International Business District, Incheon, is the tallest structure in South Korea. It is also the crown jewel of POSCO’s leading innovative technology, utilizing revolutionary features such as a 3D exterior design, a seismic force resisting system and high level security and anti-disaster measures.

Yet, NEATT, which is a mix of office spaces, a luxury hotel, serviced residences and retail stores, also serves as a model of sustainable design strategies, carefully balancing energy conservation, increased indoor environmental quality and occupant comfort. Its range of passive design strategies, which include daylighting, natural ventilation and energy efficient HVAC systems, as well as its eco-friendly, non-toxic construction materials, have ensured that the skyscraper is not only friendly to the environment, but to its human inhabitants, too.

Monte Rosa Hut

Perched above the skiing mecca of Zermatt, Switzerland, the Monte Rosa Hut is a lodging space used by hikers in route to the summit of the same name on icy glacier treks. The five-story crystal-shaped building was constructed on stainless-steel foundations with a wooden spiral interior covered by a silver aluminum shell. During its construction, materials and workers were transported by train to Zermatt, requiring 3,000 helicopter trips.

The hut uses solar power for about 90 percent of its energy and heat requirements. Excess energy is stored in valve-regulated lead-acid accumulators, which ensure power in all kinds of weather. Large windows allow the sun to heat air inside the building, and melting glaciers in the area provide the lodge’s water supply, which is collected and stored in a nearby reservoir. (Image from http://bit.ly/1AJVsUa)

Meera Sky Garden

Perhaps no other building on this list is as one with nature as the Meera Sky Garden in Sentosa, Singapore. This eye-catching, eco-friendly home was designed by Guz Architects, and it overlooks the island’s harbor.

Divided into four distinctive floors, each of which is covered with a grass roof, the home appears as if it is four separate houses, yet is still seamlessly connected by a natural element. Not only are these garden-like spaces visually pleasing, but the grassy roofs help to keep the interior temperatures at a minimum, saving energy. (Image from http://bit.ly/1ddeBTx)

Pixel

While Pixel’s chaotic, colorful exterior is the first thing one might notice about the small office building in Melbourne, Australia, its sustainable design is what really makes it noteworthy. Some of its design innovations include a panel shade system that allows natural light into the office, while at the same time, reducing glare and heat. More impressively, Pixel utilizes wind turbines to generate its own electricity.

As Australia’s first carbon neutral office building, Pixel was also the first building to ever be granted a perfect score on the country’s Green Star sustainability rating system. (Image from http://bit.ly/1JoxIpS)

Bank of America

When the Bank of America building was erected in Manhattan, New York in 2009, it set the standard for all environmentally responsible buildings to come. Its base-to-roof insulating glass external structure enhances heat insulation while creating a large source of natural light, while the building’s extensive solar panels produce energy for the building.

And the Bank of America knows how to save water. Its greywater system collects and recycles waste from sinks and water fountains into the refrigeration system, while its catchment systems collect and save around 45 inches of rain that fall on the site each year. Such sustainable features landed the skyscraper the LEED Platinum Award, the highest level of the internationally recognized green building rating system.

The Change Initiative

In a city that is seemingly ever under construction, The Change Initiative (TCI), an eco-lifestyle shop that stocks everything from environmentally-conscious detergent to greywater recycling tools, sets itself apart from other buildings in Dubai.

Often noted as one of the most sustainable commercial buildings in the world, the majority of the materials used to create TCI are recyclable. The roof is coated with heat-reflective paint and is embellished with solar panels that generate about 40 percent of the building’s energy, while the building’s outer structure has three times the insulation of the average building. (Image from Gundeep Singh)
