Abstract: Call information can be used for scheduling runs of elevators in a group of elevators. The scheduling is done so that based on the call allocations a schedule of expected movements, accelerations and decelerations can be computed. Then the movements, accelerations and decelerations may be controlled in order to improve energy efficiency or for controlling the movement in such manner that the energy consumption peaks or duration of these peaks is reduced.

Abstract: A method for providing well access in an elevator well having at least one elevator car moveable in the elevator well, includes the following steps: a well access operating mode of the elevator is activated, in which well access operating mode the elevator car will not respond to any landing calls, group controller commands or to any other remote commands, upon activation of the well access operating mode the car is controlled to travel a set distance up or down, the car is controlled to stop at said distance for a given time, the elevator will automatically exit the well access operating mode and return back to service if within the given time no well entrance, e.g. landing door, is opened. After non authorized activation of the well access operating mode, the elevator is automatically returned to service, which reduces the danger of off-service times of the elevator based on misuse of activation signals.
