The human behavior : a tracking system to follow the human occupancy

Various control strategies have been adopted to improve energy efficiency in commercial office buildings, particularly the alignment of energy consumption for space conditioning and lighting patterns with human occupancy. Considerable uncertainty however exists in these patterns but advancement in information and communication technology (ICT) has made it possible to reduce these uncertainties. More fine-grained building occupants information can now be gotten in real-time for dynamic demand-driven space lighting and conditioning controls. In this paper the performance of one of such technologies; radio frequency identification (RFID) system is accessed in the determination of human occupancy and location from experiments carried out in a typical office building in the Netherlands. The correlation between energy use by office appliance and human occupancy was also investigated. Furthermore, steps that could be taken to improve energy consumption for comfort through a demand-driven process control strategy are identified
