A network of wireless remote climate sensors in a heating, ventilation, and air conditioning (HVAC) system permits the creation of personalized microclimates within an enclosed space. In addition to collecting temperature and humidity data, the wireless remote climate sensors can detect whether the enclosed space is occupied by a human. Human detection is made possible by optional cameras, microphones, and gas sensors on the wireless remote climate sensors. As the human moves throughout the enclosed space, the HVAC system is able to track the human's movement using the wireless remote climate sensors. The HVAC system may adjust airflow to different portions of the enclosed space based on the human's location. The result is an efficient use of system resources to keep users at their ideal temperature.

According to the present invention, a controller determines whether the current performance of a piece of equipment satisfies a determination criterion, on the basis of the current state of the equipment, acquired by a sensor. If the controller determines that the current performance of the equipment does not satisfy the determination criterion, the controller calculates a parameter with which the performance of the equipment satisfies the determination criterion, on the basis of the current state of the equipment, acquired by the sensor, and the determination criterion. The controller changes a parameter managed by a storage device to the parameter calculated by the controller.
