A system for disaggregating residential electricity consumption by appliance

摘要

THERE are many oppotunities for reducing electricity consumption in buildings, but identifying and quantifying them is often perceived to be too time-consuming or too expensive to justify. The average consumer currently receives a monthly bill as a signal of their consumption. Most building owners don't have a good sense of how much energy different appliances and activities consume. In fact, people consistently over-estimate the impact of less-energy-consuming appliances and less-effective conservation activities, and under-estimate the impact of more-energy-consuming appliances and more-effective conservation activities [1].
