Abstract

A utility control system governs provision of genuine on-demand lighting, as well other utilities as in heating, ventilation and air conditioning (“HVAC”) in territories of a building in accordance with occupant demand. In lighting control, the present invention enacts on-demand illumination anterior to the occupant entering a normally dimmed/unlighted territory; lighting is provided immediately anterior to occupant entry into an oncoming territory. As the occupant leaves each territory, lighting provision is suspended/terminated in that territory for energy conservation. Signals and commands received by the utility control system from a plurality of override switches, interactive sensors and occupancy sensors within each monitored territory, as well as the control units of an elevator control system (“ECS”), a Building Management System (“BMS”) and a client computer govern the utility control system for configuring automated lighting provision. The utility control system predicts an occupant traversal path and provides the occupant with the best-suited lighted environments in each territory of the occupant traversal path.

or,

b. door handle rotation;

or,

c. insertion/withdrawal/reading of a chip embedded key/key card;

or,

d. activation of a door bell.

5. The system of claim 1, wherein said interactive sensor is a compression switch embedded within a door or a door frame, wherein the interactive sensor is configured to generate and send signals to one or more said controllers in response to movement of door lock components including the latch bolt, or opening/closing of the door.

6. The system of claim 1, wherein one or more said elevator car detection sensors are configured to detect location, landing and departure of elevator car and/or open/closed state of elevator car doors.

7. The system of claim 1, wherein said interactive sensor is a reader and is configured to read information stored in an electronic integrated circuit chip;

wherein the electronic integrated circuit chip is embedded in a device selected from a key card or a personal electronic device.

10. The system of claim 1, wherein said controller is communicatively linked with at least one elevator control system via one or more communicative linkages, wherein data encompassing operation information is sent and received between said controller of said system and said elevator control system, comprising:

a. said controller of said system sending signals and data encompassing information pertaining to system operation to one or more processor mounted control units of said elevator control system;

b. said controller of said system receiving from one or more said control units of said elevator control system signals and data encompassing information pertaining to said elevator control system operation.

8. A method of operating a utility control system, comprising:

a. sending signals, commands and/or information by one or more said controllers to one or more external control systems for determining the respective unique configurations and activation of separate operations;

b. receiving by one or more said controllers sensor signals, commands and/or information sent from one or more said external control systems for controlling one or more said light fixtures and/or utility provision characterized in HVAC in said building zone;

c. receiving signals by one or more said controllers sent from an occupancy sensor through a wired or wireless linkage;
