ENERGY DISAGGREGATION METHODS AND SYSTEMS USING WEATHER DATA

Certain examples described herein provide a system and a method for disaggregating energy load data for a building. The system () may have an energy load data interface () to receive energy load data () originating from energy use sensors for the building; a weather data interface () to receive weather data () for a location that includes the building; a weather adjustment pre-processor () to process the energy load data and the weather data and to determine a weather-dependent energy use component () of the energy load data and a weather-independent energy use component () of the energy load data; a baseline adjustment pre-processor () to process the weather-independent energy use component of the energy load data and determine a baseline energy use component () of the energy load data, wherein the baseline adjustment pre-processor is configured to remove the baseline energy use component from the weather-independent energy use component to determine a variable energy use component () of the energy load data; and an energy use disaggregator () to process the variable energy use component of the energy load data and determine a plurality of time-varying load components () of the energy load data.
