SYSTEM AND METHOD FOR REDUCING PEAK AND OFF-PEAK ELECTRICITY DEMAND BY MONITORING, CONTROLLING AND METERING HIGH INTENSITY FLUORESCENT LIGHTING IN A FACILITY
First Claim
1. A method for monitoring, controlling and metering HIF lighting fixtures in a facility, the method comprising:
- controlling operation of the HIF lighting fixtures by transmitting a time-based control signal to one or more of the HIF lighting fixtures according to a time-based control scheme;
modifying the time-based control scheme by transmitting a demand-based control signals to one or more of the HIF lighting fixtures;
overriding the time-based control signals and the demand-based control signals by providing an override signal to one or more of the HIF lighting fixtures; and
quantifying a reduction in power obtained by controlling the HIF lighting fixtures with any one or more of the time-based control signal, the demand-based signal and the override signal.

Abstract
A method of reducing electricity usage during peak demand periods includes the steps of establishing predetermined load reduction criteria representative of a desire by a power provider to reduce loading on an electricity supply grid, and coordinating with a facility having HIF lighting equipment to permit the power provider to turn-off one or more of the HIF lighting equipment by sending instructions to a master controller at the facility in response to the predetermined load reduction criteria, and establishing a list of HIF lighting equipment to be turned-off in response to the instructions, and configuring the master controller to send an override control signal to the HIF lighting equipment to implement the instructions, and configuring the HIF lighting equipment to send a response signal to the master controller providing a status of the HIF lighting equipment.

7. A system for monitoring, controlling and metering HIF lighting fixtures in a facility, the system comprising:
-
at least one sensor operable to measure a parameter within an interior space of the facility and to send a sensor signal representative of the parameter to a master controller; a plurality of local transceiver units in communication with the master controller, each local transceiver unit configured for installation on each of the HIF lighting fixtures; the master controller in communication with the sensor and the local transceiver units, and operable to; (a) provide a control signal to the local transceiver units to control operation of the HIF lighting fixtures according to a time-based scheme; (b) process the sensor signal and provide a control signal to control operation of one or more of the HIF lighting fixtures according to a demand-based scheme; (c) receive and process override instructions and provide an override control signal to control operation of one or more of the HIF lighting fixtures according to an override-based scheme; (d) receive a signal from the local transceiver units representative of a status of the HIF lighting fixtures associated with the transceiver units; (d) quantify a reduction in power usage achieved by the demand-based scheme and the override-based scheme; and (e) transmit data representative of the reduction in power usage to a user. - View Dependent Claims (8, 9, 10, 11)
