Sky lobby
From Wikipedia, the free encyclopedia
A sky lobby is an intermediate floor where people can change from an express elevator that only stops at the sky lobby to a local elevator which stops at every floor within a segment of the building. When designing very tall (supertall) buildings supplying enough elevators is a problem. The sky lobby, first used in the John Hancock Center in Chicago[1] , is one approach to the problem.
