Abstract :
This study evaluates how the disaggregation of appliances from a central location is impacted by the sample-rate used to measure a household´s energy use. The sample-rate parameter is the deciding factor for choosing hardware requirements necessary for designing an appliance-level information system that can scale to general households. However, the impact of sample-rate on appliance disaggregation accuracy has so far not been evaluated.
