Claim 7:
8. A method for optimizing an energy consumption by a system for conveying passengers in a building, wherein the system includes a passenger conveyance installation being one of an elevator, an escalator and a moving walkway, the method comprising the steps of:
identification of a conductor via which the passenger conveyance installation in a standby operation is supplied with a standby current from a main energy supply of the building;
measurement of an electrical parameter of current flowing in the identified conductor at an input side of a main switch, the identified conductor being connected to the main energy supply at the input side of the main switch and being connected at an output side of the main switch to the passenger conveyance installation;
detection of a standby operation of the passenger conveyance installation using the measured electrical parameter and performing of the following steps as soon as the passenger conveyance installation is in the standby operation;
continuous measurement of a standby current in the identified conductor; and
supply from an energy store of the system a current corresponding to the measured standby current into the identified conductor at the input side of the main switch.
