Elevator system

System for evacuating people from a building using the elevators of an elevator system as an aid, in which the power available for the elevator system to use is smaller than in normal operating mode, wherein the system comprises:

• a monitoring unit for monitoring the numbers of people to be moved between the different floors of the building;
• group control of the elevators for defining the floor of the greatest priority;
• group control of the elevators for driving a free elevator to the defined floor without stopping if the starting of the elevator does not cause an exceedance of the power available for use;
• and
• group control of the elevators for driving a filled elevator at the defined floor to the exit floor of the building if the starting of the elevator does not cause exceedance of the power available for use.

A computer program product embodied on a computer-readable medium, for evacuating people from a building using the elevators of an elevator system as an aid, in which the power available for the elevator system to use is smaller than in normal operating mode, wherein the computer program product comprises computer-executable instructions of:

• monitoring the numbers of people to be moved between the different floors of a building;
• defining the floor of the greatest priority;
• driving a free elevator without stopping to the defined floor if the starting of the elevator does not cause exceedance of the power available for use;
• and
• driving a filled elevator without stopping to the exit floor of the building if the starting of the elevator does not cause exceedance of the power available for use.
