Abstract: Systems and methods of branch circuit load estimation are disclosed. A total power usage of a main line of an electrical distribution panel that includes a plurality of branch circuits with at least two of the plurality of branch circuits coupled to the main line can be determined. A first power usage of the main line is determined with a first of the two branch circuits decoupled from the main line, and a first time period that the first branch circuits is coupled with the main line is identified. A kilowatt-hour energy usage value of the first branch circuit is estimated based on the first time period and a differential between the total power usage and the first power usage.

Abstract: An actuator for use with an HVAC system in a building having a door includes a thermostat having a setback function, and a wireless switch placed remotely from the thermostat. The switch is for being disposed on or adjacent the door. Upon actuation of the switch, a first signal is sent to the thermostat for placing the HVAC system in a setback condition.

Abstract: A lighting control system includes an enhanced occupancy sensor and/or an enhanced power pack, allowing for more sophisticated and/or accurate lighting control and energy management capability. In one example, the power pack and/or occupancy sensor is networkable, providing the capability to link and coordinate multiple power pack/occupancy sensor combinations, thereby providing zone-wide control and energy management features, such as, coordinated lighting of several areas, the ability to force lights on in a life-safety situation, and the ability to control other equipment in a monitored area (e.g., an air conditioning and/or heating system) responsive to detected occupancy in the area. The networkable power pack includes installation and wiring to an occupancy sensor that is substantially identical to a conventional power pack and therefore may be implemented as a “drop-in” component in a legacy lighting control system, without requiring changes to the occupancy sensors or wiring of the system.

Abstract: A lighting control system includes an enhanced occupancy sensor and/or an enhanced power pack, allowing for more sophisticated and/or accurate lighting control and energy management capability. In one example, the occupancy sensor provides additional information, such as information about movement detected in the monitored area, in the form of a signal superimposed on the occupancy signal, and a specialty power pack is configured to detect and respond to the superimposed information signal, thereby providing enhanced functionality to the lighting control system. The superimposed signal conveying the additional information is made high-speed/short-duration such that it is “invisible” to a conventional power pack and the occupancy sensor remains compatible with conventional power packs. The enhanced occupancy sensor may therefore be used seamlessly with both conventional and specialty power packs, and may be implemented as a “drop-in” component for legacy lighting control systems.
