Method of and system for automatically adjusting airflow

A system comprising:

• a plurality of controlled supply registers, each controlled supply register adapted for placement within a corresponding terminus of a portion of duct work for a forced-air building environmental control system, each register comprising:
• an airflow adjusting mechanism that controls a size of an aperture through which air passes when exiting the terminus of the portion of the duct work,
• a register sensor that senses a value of an environmental variable inside the corresponding portion of the duct work into which the register is placed,
• a register communication system for transmitting and receiving information, and
• a register processor system that controls the airflow adjusting mechanism;
• a plurality of sensor platforms, each sensor platform sensing a value of an environmental variable in a space into which the air exiting the corresponding terminus of the portion of the duct work passes, each sensor platform comprising:
• a sensor for sensing the value of the environmental variable, and
• a sensor communication system for transmitting and receiving information;
• and a controller comprising:
• a controller communications system for transmitting and receiving information, and
• a controller processor system,
• wherein:
• the controller receives information about desired set points for the environmental variables in each corresponding space,
• the controller receives information from the plurality of registers about the values of the environmental variables sensed by the plurality of registers,
• the controller receives information from the plurality of sensor platforms about the values of the environmental variables sensed by the plurality of sensor platforms,
• the controller processor system retrieves a total target airflow for the forced-air building environmental control system,
• the controller processor system determines an individual register target airflow for each of the plurality of registers to achieve the desired set points for the environmental variables in the spaces and to achieve the total target airflow,
• the controller transmits information about the individual register target airflows,
• each register receives information about the individual register target airflow corresponding to the register, and
• in response to receiving the corresponding individual register target airflow, the corresponding register processor system controls the corresponding register adjusting mechanism to achieve the corresponding target airflow.
