US 2015/0178633 A1 · SYSTEMS AND METHODS FOR DETERMINING THE UNCERTAINTY IN PARAMETERS OF AN ENERGY USE MODEL

Abstract

Systems and methods for determining the uncertainty in parameters of a building energy use model are provided. A disclosed method includes receiving an energy use model for a building site. The energy use model includes one or more predictor variables and one or more model parameters. The method further includes calculating a gradient of an output of the energy use model with respect to the model parameters, determining a covariance matrix using the calculated gradient, and using the covariance matrix to identify an uncertainty of the model parameters. The uncertainty of the model parameters may correspond to entries in the covariance matrix.
