The AmbientFactors application has been designed to collect buildings occupants’ preferences about ambient factors including temperature, lighting and air flow. In addition, it asks for some optional information regarding the clothing level and appliances in use. The application covers University of Southern California (USC) campus buildings. The occupants feedback is used in implementing adaptive control strategies for temperature, lighting and airflow. Accordingly, using the application, buildings’ occupants provide valuable information which leads to occupant comfort increase and building energy consumption decrease.
