Building Occupancy and Smart Metering

Buildings have been recognized as one of the major carbon emission sources to maintain the basic requirement of building occupants, and occupant has been widely recognized as key building energy end-users. Therefore, to improve building energy efficiency, sensing, recognizing, and utilizing occupancy patterns for building demand-based control are very important and efficient ways. This chapter presents those contents: (i) Occupancy resolution for building energy-savings and its relationship between circular economy at building sector; (ii) Current occupancy sensing and related energy-efficient approach; (iii) Occupancy smart sensing with Wi-Fi network; (iv) One case study of how occupancy sensing can improve building energy efficiency.
