Title:
LIGHTING ENERGY MANAGEMENT SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO2004004423
Kind Code:
A3
Abstract:
An lighting energy management system and method for controlling lighting fixtures in a building, uses lighting fixtures, photo and occupancy sensors, personal lighting commands and an energy control unit. The energy control unit receives information from the photo and occupancy sensors and the personal controller and determines an optimal brightness command for each lighting fixture using a coordinated system of zone and fixture objects. Each zone object is associated with a building zone and each fixture object is associated with a light fixture. Each zone object ensures that lighting fixture lighting level is adjusted when a physical zone is unoccupied. Each fixture object uses sensors and personal inputs to determine a desired brightness level and uses a load shedding and daylight compensation to determine a daylight adjusted brightness level. The energy control unit determines an optimal brightness command based on these levels to minimize the energy required by the lighting fixtures.
