First Claim
1. A method for monetizing faults in a building, the method comprising:
- evaluating, at a processing circuit, an energy consumption model for the building to estimate an amount of energy consumed by the building as a function of a plurality of parameters;
modulating, by the processing circuit, a fault parameter of the energy consumption model and using the energy consumption model to estimate an amount of energy consumed by the building at multiple different values of the fault parameter;
generating, by the processing circuit, a first set of variables comprising multiple first differences in the fault parameter, each of the first differences corresponding to a difference between a target value of the fault parameter and one of the multiple different values of the fault parameter;
generating, by the processing circuit, a second set of variables comprising multiple second differences in the amount of energy estimated by the energy consumption model, each of the second differences corresponding to a difference between an amount of energy estimated by the energy consumption model with the fault parameter at the target value and one of the amounts of energy estimated by the energy consumption model with the fault parameter at one of the multiple different values;
using the first set of variables and the second set of variables to develop, by the processing circuit, a regression model for the fault parameter, the regression model estimating a change in the amount of energy consumed by the building as a function of a change in the fault parameter; and
determining, by the processing circuit, a cost of a fault associated with the fault parameter using the regression model.

Abstract
A fault parameter of an energy consumption model is modulated. The energy consumption model is used to estimate an amount of energy consumption at various values of the fault parameter. A first set of variables is generated including differences between a target value of the fault parameter and the various values of the fault parameter. A second set of variables is generated including differences between an estimated amount of energy consumption with the fault parameter at the target value and the estimated amounts of energy consumption with the fault parameter at the various values. The first set of variables and second set of variables are used to develop a regression model for the fault parameter. The regression model estimates a change in energy consumption based on a change in the fault parameter. Regression models are developed for multiple fault parameters and used to prioritize faults.
