1. A system for adjusting building utilities of a controlled zone within a building occupied by a plurality of occupants, the system comprising:

  • a controlled zone having a service utility within a building, wherein each controlled zone includes a plurality of rooms;

    a plurality of tags or devices, wherein each tag or device of the plurality of tags or devices emits a signal and has a specific digital identification code assigned to a corresponding occupant that wears or carries the tag or device inside at least one room of the plurality of rooms;

    a first one or more sensors disposed in a first room in the controlled zone and emitting a search signal for any tags or devices in the first room for detecting a first subset of tags or devices of the plurality of tags or devices located in the first room during a time interval, anda second one or more sensors disposed in a second room in the controlled zone and emitting a search signal for any tags or devices in the second room for detecting a second subset of tags or devices of the plurality of tags or devices located in the second room during the time interval;

    a zonal compiler disposed in the controlled zone and wirelessly in communication with the first and second sensors;

    the zonal compiler configured to;

    communicate wirelessly with the first one or more sensors and the second one or more sensors, and with the first subset of tags or devices and the second subset of tags or devices to thereby wirelessly acquire a first group of digital identification (ID) codes corresponding to the first subset of tags or devices detected by the first one or more sensors during the time interval, and a second group of digital identification (ID) codes corresponding to the second subset of tags or devices detected by the second one or more sensors during the time interval;

    compare the first group of digital identification (ID) codes with the second group of digital ID codes;

    based on said comparison, identify a tag or device of the first subset of tags or devices as being the same as a tag or device of the second subset of tags or devices,eliminate the identified tag or device from the second group of digital identification (ID) codes to establish a corrected second group of digital identification (ID) codes, anddetermine a zonal occupancy count for the controlled zone and each room based on the acquired first group of digital identification (ID) codes and the corrected second group of digital identification (ID) codes; and

    a microprocessor that controls the service utility within the building, the microprocessor wirelessly interfaces with the first and second sensors, wherein the microprocessor immediately adjusts the service utility for each room in the controlled zone immediately upon entrance into or removal of the occupant wearing or carrying the tag or device from any room;

    wherein the microprocessor wirelessly interfaces through an interface relay with the zonal compiler to control the service utility, and the service utility is an electrical lighting.
