Frank Lloyd Wright, with a wave of his hand, dispensed with ropes in The Illinois. Instead, his fictional building used fictional nuclear-powered elevators. But today, one elevator company, ThyssenKrupp, is betting on a ropeless future. It is developing the MULTI, an elevator that travels by magnetic levitation (maglev).

The technology is now used for bullet trains. For example, Shanghai has one to ferry travelers from the Pudong business district to the airport. It can travel up to 268 miles per hour (431 km/h). The maglev system has the cars hovering over tracks, so there is no friction. The principle is the same for elevators, but they are, of course, used to run up and down.

Without a rope, multiple elevator cars can run in the same shaft, and their movement can be coordinated with sophisticated software algorithms. When one is needed on a higher floor, other cars, which might be in the way, can move horizontally to free the path. According to Prof. Cesarz, the ability to move cars aside represents one of the last remaining bottlenecks for the maglev elevator itself. ThyssenKrupp engineers are close to perfecting the switching device that will make the MULTI practical. The company has even constructed an 807-foot (246-meter) testing tower in the German town of Rottweil. When the elevator cars can seamlessly change directions, they will circulate through the building like blood cells in our arteries.

Maglev elevators are likely to have many benefits. In the immediate future, by allowing several cars to run in the same shaft, they reduce the total amount of shaft space, meaning more revenue-generating space for the building owner. Further, it can more efficiently carry people to their final destinations within the building. Since ropes are heavy, they require significant energy usage. The MULTI can reduce both energy costs and greenhouse gas emissions.

Skyscraper allows you to explore constructions and to travel through their surroundings. Use the elevator or the stairs to go up a level. The view is controlled with a number key and arrows. The Space Bar is to jump and Shift is to accelerate.

In 1857, Elisha Otis introduced the safety elevator at the E. V. Haughwout Building in New York City, allowing convenient and safe transport to buildings' upper floors. Otis later introduced the first commercial passenger elevators to the Equitable Life Building in 1870, considered by some architectural historians to be the first skyscraper. Another crucial development was the use of a steel frame instead of stone or brick, otherwise the walls on the lower floors on a tall building would be too thick to be practical. An early development in this area was Oriel Chambers in Liverpool, England. It was only five floors high.[26][27] The Royal Academy of Arts states, "critics at the time were horrified by its "large agglomerations of protruding plate glass bubbles". In fact, it was a precursor to Modernist architecture, being the first building in the world to feature a metal-framed glass curtain wall, a design element which creates light, airy interiors and has since been used the world over as a defining feature of skyscrapers".[28]

The architect, Major William Le Baron Jenney, created a load-bearing structural frame. In this building, a steel frame supported the entire weight of the walls, instead of load-bearing walls carrying the weight of the building. This development led to the "Chicago skeleton" form of construction. In addition to the steel frame, the Home Insurance Building also utilized fireproofing, elevators, and electrical wiring, key elements in most skyscrapers today.[31]

Modern skyscrapers are built with steel or reinforced concrete frameworks and curtain walls of glass or polished stone. They use mechanical equipment such as water pumps and elevators. Since the 1960s, according to the CTBUH, the skyscraper has been reoriented away from a symbol for North American corporate power to instead communicate a city or nation's place in the world.[37]

Elevators are characteristic to skyscrapers. In 1852 Elisha Otis introduced the safety elevator, allowing convenient and safe passenger movement to upper floors. Another crucial development was the use of a steel frame instead of stone or brick, otherwise the walls on the lower floors on a tall building would be too thick to be practical. Today major manufacturers of elevators include Otis, ThyssenKrupp, Schindler, and KONE.

The invention of the elevator was a precondition for the invention of skyscrapers, given that most people would not (or could not) climb more than a few flights of stairs at a time. The elevators in a skyscraper are not simply a necessary utility, like running water and electricity, but are in fact closely related to the design of the whole structure: a taller building requires more elevators to service the additional floors, but the elevator shafts consume valuable floor space. If the service core, which contains the elevator shafts, becomes too big, it can reduce the profitability of the building. Architects must therefore balance the value gained by adding height against the value lost to the expanding service core.[79]

Many tall buildings use elevators in a non-standard configuration to reduce their footprint. Buildings such as the former World Trade Center Towers and Chicago's John Hancock Center use sky lobbies, where express elevators take passengers to upper floors which serve as the base for local elevators. This allows architects and engineers to place elevator shafts on top of each other, saving space. Sky lobbies and express elevators take up a significant amount of space, however, and add to the amount of time spent commuting between floors.

Other buildings, such as the Petronas Towers, use double-deck elevators, allowing more people to fit in a single elevator, and reaching two floors at every stop. It is possible to use even more than two levels on an elevator, although this has never been done. The main problem with double-deck elevators is that they cause everyone in the elevator to stop when only person on one level needs to get off at a given floor.

Another disadvantage of very high skyscrapers is the loss of usable floorspace, as many elevator shafts are needed to enable performant vertical travelling. This led to the introduction of express lifts and sky lobbies where transfer to slower distribution lifts can be done.

Skyscrapers have considerable mass, requiring a stronger foundation than a shorter, lighter building. In construction, building materials must be lifted to the top of a skyscraper during construction, requiring more energy than would be necessary at lower heights. Furthermore, a skyscraper consumes much electricity because potable and non-potable water have to be pumped to the highest occupied floors, skyscrapers are usually designed to be mechanically ventilated, elevators are generally used instead of stairs, and electric lights are needed in rooms far from the windows and windowless spaces such as elevators, bathrooms and stairwells.

A portion of the operational energy increase in tall buildings is related to the usage of elevators because the distance traveled and the speed at which they travel increases as the height of the building increases. Between 5 and 25% of the total energy consumed in a tall building is from the use of elevators. As the height of the building increases it is also more inefficient because of the presence of higher drag and friction losses.[86]

People are obviously unwilling to climb more than a few sets of stairs, but that was the only available way to transport themselves in this new vertical urban space before the elevator was invented. This is where Elisha Otis, the next key person in the development of the skyscraper-network stepped in. Otis was a "resourceful Yankee tinkerer and inventor" who developed two key contributions to the skyscraper (2). First, for the early non-electrical elevators, he developed a safety mechanism in which the elevator would be caught on metal teeth protruding from the side of the elevator shaft instead of dangerously plunging to the bottom; his patent is shown below. This allayed the public's fear of deadly elevator crashes. Otis famously demonstrated his device at the 1854 Crystal Palace Exposition in New York, using himself as a test dummy:

Later, in his second great contribution to skyscrapers, Otis' now-famous elevator company solved an important problem concerning electrical elevators in 1903, when it developed a better leveling system that ended the "intricate and tricky landing maneuvers at each floor", which elevator-riders of the time were accustomed to. This allowed electric elevators to technologically win out, significantly speeding up transport within a skyscraper. Once the elevator had been optimized for popular use, it only contributed to the growth of taller and taller skyscrapers. The 1930 skyscraper study emphasizes that elevator technology was very expensive to install and maintain at that early stage of the skyscraper. The authors put forth the following table to show the comparison between elevator cost increase and rentable area increase as buildings got taller. Clearly these ratios became more desirable as a building grew, calling for taller and taller skyscrapers to be built. 17dc91bb1f
