Smart building, which delivers useful services to residents at the lowest cost and maximum
comfort, has gained increasing attention. HVAC equipment is a particularly expensive and
energy consuming of building operation. A variety of emerging information technologies has
been adopted. As a result, the concept of “demanddriven HVAC control” is a hot research
topic. In this work, we investigated the issue of building occupancy estimation by using a
wireless CO2 sensor network. The concentration level of indoor CO2 is a good indicator of …
