Claims16
An elevator system for a multi-level architectural structure, the elevator system comprising
- an elevator controller for an elevator in a hoistway, wherein the elevator controller effects a first determination of whether passengers or goods are in the elevator and effects a power mode for the elevator based on the first determination,
- wherein:
- when the elevator controller determines there are no passengers within the elevator, the elevator controller effects a first power reduction mode of a plurality of power reduction modes, the first power reduction mode includes reducing electrical power for a first set of implements to respective preset levels, the first set of implements including one or more of (i) elevator lights, and (ii) air conditioning and ventilation systems;
- and
- when the elevator controller determines there are no passengers and no goods within the elevator, the elevator controller effects a second power reduction mode of the plurality of power reduction modes, the second power reduction mode includes (i) reducing electrical power for the first set of implements to the respective preset levels, and one or more of (ii) reducing electrical power to a call panel display within the elevator to a respective preset level and (iii) directing the elevator to a first level and parking the elevator at the first level.

A method of operating an elevator system for a multi-level architectural structure, wherein
- the elevator system includes an elevator controller for an elevator in a hoistway, and
- the method comprises:
- the elevator controller effects a first determination of whether passengers or goods are in the elevator and effects a power mode for the elevator based on the first determination,
- wherein:
- when the elevator controller determines there are no passengers within the elevator, the elevator controller effects a first power reduction mode of a plurality of power reduction modes, the first power reduction mode includes reducing electrical power for a first set of implements to respective preset levels, the first set of implements including one or more of (i) elevator lights, and (ii) air conditioning and ventilation systems;
- and
- when the elevator controller determines there are no passengers and no goods within the elevator, the elevator controller effects a second power reduction mode of the plurality of power reduction modes, the second power reduction mode includes (i) reducing electrical power for the first set of implements to the respective preset levels, and one or more of (ii) reducing electrical power to a call panel display within the elevator to a respective preset level and (iii) directing the elevator to a first level and parking the elevator at the first level.
