1. A method for generating an energy use model of a building comprising: receiving, at a processing circuit, building data indicative of a first type of building variable, the processing circuit comprising a processor, memory, and an interface; receiving, at the processing circuit, additional building data correlated to an energy use of the building; generating, by the processing circuit, a building variable model that estimates the building variable as a function of the additional building data, the building variable comprising a correlated portion that is correlated with the additional building data and an uncorrelated portion that is uncorrelated with the additional building data; determining, by the processing circuit, the portion of the building variable that is uncorrelated with the additional building data by calculating a residual of the building variable model, the residual representing a non-random variable that is correlated with the building variable and uncorrelated with the additional building data; and using the additional building data and the uncorrelated portion of the building variable to generate the energy use model of the building, wherein the energy use model estimates the energy use of the building as a function of the additional building data and at least one of the residual and the variable represented by the residual.
