ENERGY SAVING OPERATION SYSTEM OF ELEVATOR

PROBLEM TO BE SOLVED: To suppress the total electric power of a plurality of elevators at respective time points and to reduce an effect (decline of operation service) on users using the respective elevators. SOLUTION: The energy saving operation system for the elevators for controlling the operation of the plurality of elevators includes a power profile calculation means 203 for calculating time course of used power values of the respective elevators as a power profile from at least either of the car direction, a hall call, a car call, the number of passengers or traffic information of a building and power suppression value calculation means (204, 205, 211) for calculating the total electric power suppression value for suppressing the total use power value to a threshold value or lower from a total power profile which is produced by adding up the power value profile and the total power suppression value is calculated as the power suppression value of the respective elevators and the energy saving operation is conducted for the respective elevators based on the power suppression value.
