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 (410) may have an energy load data interface (420) to receive energy load data (422) originating from energy use sensors for the building; a weather data interface (430) to receive weather data (432) for a location that includes the building; a weather adjustment pre-processor (440) to process the energy load data and the weather data and to determine a weather-dependent energy use component (442) of the energy load data and a weather-independent energy use component (444) of the energy load data; a baseline adjustment pre-processor (450) to process the weather-independent energy use component of the energy load data and determine a baseline energy use component (456) 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 (458) of the energy load data; and an energy use disaggregator (460) to process the variable energy use component of the energy load data and determine a plurality of time-varying load components (462) of the energy load data.
