Abstract: This thesis focuses on developing cost-effective, energy-efficient and occupant-satisfied cooling solutions in buildings. Compressor-based cooling has a large impact on energy consumption in modern buildings, particularly in the tropics. Increasing cooling set point can bring financial benefits while the compromised comfort can be compensated by elevated air speed. In this thesis, a human tracking fan system is proposed by using geofence and camera-based indoor localization. Also, a patented technology to optimize the operation of a system of fans is present. Additionally, since occupancy information plays an important role in building cooling, a robust filter based on a more flexible noise model is proposed to improve the precision of position estimation for indoor positioning and tracking. This work aims to make the building more like a context-aware, interactive facility optimized for productivity and efficiency than a fixed structure with independent utility systems.
