Abstract

A system and associated methods of operation for regulating an environmental variable (such as ambient room temperature) within a target zone. The system includes a sensor system configured to monitor the target zone, detect one or more inhabitants present within the zone, and identify an alpha person from the one or more inhabitants. Once the alpha person is identified, a measurement sensor measures a skin parameter from the identified alpha person and generates a sensor signal communicating the measured skin parameter to an environmental control system. Upon receiving the sensor signal, the environmental control system regulates an environmental variable within the zone based on the measured skin parameter from the alpha person.
