Demand-controlled ventilation (DCV) can be adjusted based on room occupancy levels. In this study the feasibility of a visitor counting sensor network in occupancy detection was evaluated. A network with 15 sensor spots and real time activity visualization was designed and assembled at the Aalto Design Factory building. Direction sensitive light beam and infrared (IR) camera sensors were used. Counting...
