Large-scale field measurements of electrical energy consumption

A computerized central data acquisition system was designed to measure the electricity consumption of both residential and commercial buildings. The system records hourly electricity use for up to 22 separate end-uses, and automatically stores the data in a central archive for easy access to analysts. The system is currently collecting data from 450 residences and 150 commercial buildings spread geographically throughout the states of Washington, Oregon, Idaho, and Montana. With over one year's worth of data for each site, the data are being used to address many issues relating to energy conservation and load management. 9 refs., 5 figs.
