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.
The off-white segmental concrete shaft is 2.5m in diameter and 20m high, with a flat face to the north to which the lift is attached by steel fly-braces. A metal column rising from the top of the concrete shaft carries the steel cloverleaf platform above. The lift shaft has a metal frame, painted yellow, with translucent glass panels.

The first elevator shaft preceded the first elevator by four years. Construction for Peter Cooper's Cooper Union Foundation building in New York began in 1853. An elevator shaft was included in the design because Cooper was confident that a safe passenger elevator would soon be invented. [12]
As well as being a resource for the lift industry, the building is also available to companies requiring tall vertical spaces, for example companies wishing to test working-at-height safety devices. There are six lift shafts of varying heights and speeds, including a high-speed shaft with a travel of 100 metres (328 ft 1 in) and a theoretical ...
Simple core arrangement – stairs "wrapping around" elevator shaft. In architecture, a core is a vertical space used for circulation and services. It may also be referred to as a circulation core or service core. A core may include staircases, elevators, electrical cables, water pipes and risers.
Because they use up valuable floor area (just like elevator shafts), engineers try to minimize the number of mechanical floors while allowing for sufficient redundancy in the services they provide. As a rule of thumb, skyscrapers require a mechanical floor for every 10 tenant floors (10%), although this percentage can vary widely (see examples ...
The piston effect has to be considered by building designers in relation to smoke movement within an elevator shaft. [4] A moving elevator car forces the air in front of it out of the shaft and pulls air into the shaft behind it with the effect most apparent in elevator systems with a fast moving car in a single shaft. This means that in a fire ...
