1. A method for analyzing energy savings for a building comprising:
receiving a set of historical energy usage data for the building; receiving a set of weather data for the building; receiving a set of operations parameters for the building; receiving a set of building physical parameters for the building; determining a baseline building configuration from the set of operations parameters and the set of building physical parameters; conducting a first energy consumption simulation of the baseline building configuration to determine a baseline energy usage profile; determining a calibrated building configuration and a calibrated energy usage profile from the baseline building configuration, the set of historical energy usage data and the baseline energy usage profile; modifying the calibrated building configuration with a first set of energy improvement measures to determine a hypothetical building configuration; conducting a second energy consumption simulation of the hypothetical building configuration to determine a hypothetical energy usage profile; wherein the step of receiving the set of operations parameters further comprises specifying an average occupancy time for an occupied day; determining a first correlation coefficient related to curve shape between the actual monthly energy consumption and the calibrated monthly energy consumption; determining a second correlation coefficient related to closeness between data points between the actual monthly energy consumption and the calibrated monthly energy consumption; evaluating the second comparison as a numerical combination of the first correlation coefficient and the second correlation coefficient; wherein the first correlation coefficient is a Pearson correlation coefficient; wherein the second correlation coefficient is a root mean square (RMS) correlation coefficient; wherein the numerical combination is an average of a difference between the Pearson correlation coefficient and a first predefined number and the difference between the RMS correlation coefficient and a second predefined number; wherein the step of determining a calibrated building configuration and a calibrated energy usage profile from the baseline building configuration, the historical energy usage and the baseline energy usage profile further comprises:
determining an actual monthly energy consumption from the set of historical energy usage data;determining a baseline monthly energy consumption from the baseline energy usage profile;performing a first comparison between the actual monthly energy consumption and the baseline monthly energy consumption;setting the calibrated building configuration equal to the baseline building configuration;setting the calibrated energy usage profile equal to the baseline energy usage profile;if the first comparison does not meet a calibration condition, then:
adjusting the calibrated building configuration;performing a third energy consumption simulation based on the calibrated building configuration to determine the calibrated energy usage profile including a calibrated monthly energy consumption;performing a second comparison between the actual monthly energy consumption and the calibrated monthly energy consumption;iteratively adjusting the calibrated building configuration;iteratively performing the third energy consumption simulation and iteratively performing the second comparison until the second comparison meets a calibration condition; and,if the first comparison or the second comparison meets the calibration condition:
then reporting the calibrated building configuration and the calibrated energy usage profile. |
