Abstract

An arrangement for use in a control system within a building includes a plurality of sensor microsystems (12, 406, 407, 408) configured to obtain environmental information regarding a plurality of areas in a building and a processing circuit (18, 318, 412, 416). The processing circuit is operable to obtain data representative of the environmental information regarding the plurality of areas in the building under a first set of operating parameter values. The processing circuit (18, 318, 412, 416) is further operable to change an operating parameter and obtain data representative of the environmental information regarding the plurality of areas under the changed set of operating parameter values. The processing circuit (18, 318, 412, 416) is also operable to store the data representative of the environmental information under the changed operating parameter values in a knowledge base. At a subsequent time, the processing circuit employs (18, 318, 412, 416) the knowledge base to adjust the operating parameter values.
