Claim Text:
1. A system for adjusting a ventilation rate of each of a plurality of ventilation zones within a building occupied by a plurality of occupants, the system comprising: (a) a plurality of tags, each tag of the plurality of tags having a digital ID code that is assigned to a corresponding occupant of the plurality of occupants, wherein a ventilation zone of the plurality of ventilation zones includes a first room and a second room; (b) a first one or more tag detectors for detecting a first subset of tags of the plurality of tags located in the first room during a time interval, and a second one or more tag detectors for detecting a second subset of tags of the plurality of tags located in the second room during the time interval; (c) a plurality of zonal compilers assigned to the plurality of ventilation zones and including a zonal compiler assigned to the ventilation zone, the zonal compiler configured to: (d) one or more DCV processors for wirelessly interfacing with the plurality of zonal compilers, wherein at least one of the one or more DCV processors is configured to receive the zonal occupancy count from the zonal compiler and compute a zonal ventilation rate based on the received zonal occupancy count and a floor area of the ventilation zone; and (e) one or more HVAC interfaces for wirelessly interfacing with the one or more DCV processors, wherein the one or more HVAC interfaces adjusts the ventilation rate for the ventilation zone to conform to the zonal ventilation rate computed by the one or more DCV processors.
