This paper investigates recent advances in elevator technology and examines their impact on tall building development. It maps out, organizes, and collates complex and scattered information on multiple aspects of elevator design, and presents them in an accessible and non-technical discourse. Consider, however, that each day, more than 7 billion elevator journeys are taken in tall buildings all over the world . 20 years are probably the greatest advances we have seen in tall buildings . Indeed, the race to build ever taller skyscrapers has sparked fierce competition among lift manufacturers to build faster, more efficient, safer, more comfortable and more economical elevators. Similarly, Andreas Bernard’s research shows how elevators have been responsible for reshaping modern cities by concentrating large masses of people and activities in smaller areas, creating vibrant communities. Spatially speaking, the elevator’s role has been no less profound than that of the automobile in transforming modern cities.
In addition to highlighting the importance of elevators in the development of our cities, this paper aims to educate about the intersection of green technologies with energy efficient elevators. New innovations are leading to the introduction of energy efficient elevators that not only consume less energy, but also produce clean energy. Restrictive building codes in some countries, including the United States, are often a barrier to employing innovative, emerging, elevator technologies. Governments should consider financial incentives, perhaps in the form of tax credits, for the incorporation of green elevators into future skyscrapers and the retrofitting of green elevators into older buildings. The paper follows a simple structure. First, it describes recent technological advancements in elevator design.
Empire State Building in New York. By improving the energy efficiency in existing and new equipment, elevators and escalators can contribute to current energy and climate targets in Europe. Quantitative studies on energy consumption of newer and older elevator technologies are now being conducted to assess the value of the new technologies. In this regards, ISO 25745-2:2015 standards are used to help to estimate energy consumption. These standards provide measured values and calculations on an annual basis for different types of elevators and present the data according to different energy classification systems for new, existing, and modernized elevators.
