Sky lobby
A sky lobby (from the English sky for sky and lobby as reception hall) is a floor in high-rise buildings that is primarily used by visitors to change the elevator .
When planning skyscrapers , it is often a problem to provide enough elevators: For example, visitors who want to go to a high floor would have to stop at a large number of floors on the way to allow other passengers to get on and off. In order to achieve moderate travel times, more elevator shafts are required, which in turn reduces the usable floor space.
A sky lobby offers a solution to the problem: so-called express elevators are built into the skyscraper and only stop on the ground floor and in the sky lobby. Once there, visitors can change to a local elevator, which then serves every single floor of a building section. Often there are waste disposal facilities, snacks, small shops and the like in the sky lobby so that people from higher floors do not have to go down to the ground floor.
For the first time, a sky lobby was set up in the twin towers of the World Trade Center in New York and in the John Hancock Center in Chicago .
Take the John Hancock Center as an example
The Sky Lobby at the John Hancock Center in Chicago is on the 44th floor. It serves as a transfer point for floors 45 to 92, where private individuals live. From the ground floor, three express elevators drive to the Sky Lobby, where passengers can then switch to two groups of three local elevators each: One group serves floors 45 to 65, the other the floors 65 to 92.
The Sky Lobby of the John Hancock Center includes a swimming pool (the highest in a building in all of North America), a gym, dry cleaning, a supermarket, residents' mailboxes, a small library and, on appropriate occasions, a Election office for residents.
