The present invention discloses a method, a system and a computer program for the effective evacuation of a building in an emergency, in which at least one elevator can be used as an evacuation aid. In the method the group control of the elevators monitors the numbers of people on the different floors of the building. The floor on which it is assumed are most people is set at each moment of monitoring for a greater priority in an evacuation situation. Taking into account the limited supply power a free elevator car is directed to the floor of the greatest priority, at which the elevator is filled. The full elevator is directed without stopping to the exit floor of the building. The system monitors by means of detectors the safety of the different parts of the building and directs people if necessary to a safe evacuation location to wait for an elevator. A so-called Traffic Forecaster can be used as an aid in defining the priorities.

Elevator system

In the method of the present invention an evacuation mode is presented in an elevator system, which receives destination calls i.e. operates in accordance with so-called destination control. In the method the destination floor calls given on the evacuation floors of the building are changed in the event of an exceptional incident such that the destination floor becomes an exit floor of the building. In the method the elevator car is filled as flail as possible on one floor and the travel time to the exit floor is minimized by directing the elevator car to the escape floor without intermediate stops. The passengers to be evacuated are shown information relating to the evacuation on a display located on the destination call panel and/or inside the car of the evacuation elevator.
