First Claim
1. A method for emergency evacuation of building occupants from a multi-story building having a plurality of floors, a stairway and at least one elevator with an elevator car positionable at selected landings of the floors, the method comprising the steps of:
- determining substantially the total number of building occupants in the building by a destination call identification device, from which calls are fed into a control unit and allocated to elevators, an elevator user being then transported to a destination floor and the number of elevator users transported to destination floors being counted and stored in a memory;
detecting an emergency condition in the building;
defining at least one evacuation zone in the building during the emergency condition;
defining at least one designated floor in the building during the emergency condition;
evacuating the building occupants from the evacuation zone to the designated floor via at least one of the elevator car and the stairway.

Abstract
A method and a system for emergency evacuation of building occupants and to a method for modernization of an existing building with the evacuation system. The system is used in a multi-story building having a plurality of floors and with at least one elevator positionable at selected landings of the floors. A first device is provided for measuring the number of persons in the building and a second device is provided for detecting an emergency condition in the building. At least one control unit is provided for determining or for estimating a number of building occupants in the building. The control unit defines at least one evacuation zone in the building during the emergency condition. Based on this information, the control unit defines at least one designated floor in the building during the emergency condition. Then the system evacuates the building occupants with the elevator car and/or a stairway from the evacuation zone to the designated floor.

21. A method for modernizing an existing elevator in a multi-story building with a system for emergency evacuation of building occupants, the building having a plurality of floors, a stairway and at least one elevator with an elevator car positionable at selected landings of the floors, the method comprising the steps of:
-
installing first means for determining the number of occupants in the building, and a control unit, the first means determining the number of building occupants in the building by a destination call identification device, form which calls are fed into the control unit and allocated to elevators, an elevator user being then transported to a destination floor and the number of elevator users transported to destination floors being counted and stored in a memory; and installing second means for detecting an emergency condition in the building, the control unit being operative to define at least evacuating zone in the building during the emergency condition, the control unit being further operative to define at least one designated floor in the building during the emergency condition, whereby the building occupants are evacuated during the emergency condition with at least one of the elevator car and the stairway from the evacuation zone to the designated floor. - View Dependent Claims (22)
