Elevator power consists of power consumption in stand-by and in service. This paper designed a fuzzy controller saving stand-by power of elevators in a way that calculates the adequate number of elevators by the variable traffic volume of passenger and then powers off elevators being out of service. Also, the fuzzy controller was designed to minimize a increase of the average passenger's waiting time by the limited number of elevators in service. When the fuzzy controller designed in this paper was applied to the group elevator experimental device, The passenger's waiting time increased approximately 7.5%~9.5%, While the stand-by power saving is expected to be about 675KWh a day per unit and about 236.6KWh a year per unit.
