Today, the rising cost of energy and social trend of “going green” has put increasing pressure on commercial property owners to improve the efficiency of their investments. There is good reason for this, too. In the State of California, office buildings represent the single largest user of energy in the commercial sector. This project consisted of the design, implementation, construction, testing, and deployment of a wireless sensor network for energy and environmental monitoring in retrofit commercial office installations. The analyzed data generated by this system can be used by building management and owners to identify areas of inefficiency within the building’s major energy using systems – namely heating, ventilation, and air conditioning (HVAC) and lighting. While suitable for use in new construction, the system was designed for ease-of-use in retrofit installations in existing construction. The final system consists of a self-expanding mesh network of lightweight, battery- and line-powered sensor nodes which are installed at various locations throughout the building to gather power consumption, environmental, occupancy, and space utilization data for a complete energy audit.
