ZigBee is a wireless technology developed as an open global standard to address the unique needs of low-cost, low-power wireless sensor networks. This standard takes full advantages of the IEEE 802.15.4 physical radio specification and operates in unlicensed bands (e.g., 2.4 GHz) worldwide at different frequencies. As more and more companies make products(More)
—This paper reviews thermal comfort based control strategies for modern commercial buildings with heating, ventilating, and airconditioning (HVAC) systems. In order to make HVAC systems more energy-efficient, better system operations and control algorithms for HVAC systems are demanded. Research conducted predominately within the last decade suggests that(More)
