The “Other” Energy in Buildings: Wireless Power Metering of Plug-in Devices in Building 90 and Homes

Miscellaneous and electronic devices consume about one-third of the primary energy used in U.S. buildings, and their energy use is increasing faster than other end-uses. Although these devices have been studied for 30 years, they are not as well understood as the other end-uses due to their great variety and difficulty in collecting representative energy data for them. This talk describes a method for collecting device-level energy use data for these devices using a relatively low-cost wireless mesh networking technology. Over 600 meters were deployed across B90 and three homes to collect months of energy data. The presentation will discuss all aspects of the study including meter development, network performance, methodological findings and preliminary energy findings. Steven Lanzisera is a post-doctoral fellow in the Environmental Energy Technologies Division at LBNL where his primary research area is the monitoring and control of energy using devices in buildings using new information technologies. He also provides technical advice to EPA’s Energy Star program. Steven did his doctoral work in Electrical Engineering and Computer Sciences at the University of California, Berkeley where he studied low-energy, networked technologies including the design of radios, communication protocols, embedded systems, and wireless networks.
