High-speed elevator test tower being constructed by Thyssenkrupp in Atlanta.

In the ever-evolving landscape of urban development, the world is rapidly advancing towards a future where two-thirds of the global population will reside in cities by 2050. This urban expansion has sparked a surge in high-rise buildings, with 57 skyscrapers reaching at least 350 meters in height. Amidst this growth, Thyssenkrupp Elevator, a leading name in the Technical Building Equipment industry, is making significant strides in revolutionizing high-rise buildings.

Detlef Stoller, a specialist journalist for environmental issues, has covered the topic extensively, delving into the world's fastest elevators, innovative technologies, and sustainable solutions for high-rise buildings. One such innovation is the company's new headquarters in Atlanta, USA, which will feature a 128-meter-high elevator test tower, the tallest of its kind in the USA and one of the tallest in the world.

This test tower will house 18 elevator shafts, each designed for testing various elevator technologies. Thyssenkrupp's new headquarters will be home to high-speed elevators capable of reaching speeds of up to 18 m/s, equivalent to 65 km/h. The test tower will also showcase the world's first rope-less and sideways-moving elevator system, Multi, based on the technology of the Transrapid magnetic levitation train.

The Multi system, a testament to Thyssenkrupp's commitment to innovation, can move not only up and down but also sideways, offering unprecedented flexibility in high-rise buildings. Meanwhile, the "Twin" elevator system, featuring two cabins per elevator shaft, is already in use in the USA, promising faster and more efficient vertical transportation.

Thyssenkrupp's innovation extends beyond elevators. The company is also developing a climate buffer in the wall that can lower room temperature in minutes, providing a sustainable solution for energy consumption in high-rise buildings.

While Thyssenkrupp's focus lies primarily on vertical transportation, other companies are exploring innovative solutions for high-rise living. Otis, for instance, plans a new high-speed elevator in Atlanta, USA. The city is also home to the Coda Building of the Georgia Tech University, where the world's first Multi elevator system will be installed, scheduled for completion in early 2019.

In addition to these advancements, the article also touches upon the topic of the ten fastest elevators in the world and an idea from New York for windows that fold out to create a balcony feeling. The Jeddah, formerly known as the Kingdom Tower, is soon to be the tallest building in the world, adding another milestone to the ever-growing skyline.

As the world continues to urbanize, the need for innovative solutions in high-rise buildings becomes increasingly crucial. Thyssenkrupp Elevator, with its commitment to sustainability and cutting-edge technology, is at the forefront of this revolution, promising a future where high-rise living is not only possible but comfortable and efficient.
