This project aimed to demonstrate and evaluate a novel technology that non-intrusively monitors the electricity consumption of individual devices inside a building. Belkins Echo technology consists of a sensor and disaggregation algorithms. The sensor collects real-time voltage and current measurements at one sampling rate, and broadband high frequency HF noise measurements at a second, much higher, sampling rate. The combination of power characteristics and the HF noise from each type of device has a unique signature that results from the devices internal electrical circuit design. Echo captures this signature, which enables it to itemize electricity use of devices in the building. The performance objectives were only partially achieved. The Echo was not able to generate an accurate itemization of electricity consumption, but it was able to identify some major loads and estimate their energy consumption.
