Claim Text:
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; wherein the step of receiving the set of weather data further comprises: wherein the first energy consumption simulation calculates a cooling load factor for a month (CLF(m)) from the cooling degree days for a month (CDD(m)) and heating degree days for a month (HDD(m)) according to the equation: wherein the first energy consumption simulation calculates a heating load factor for a month (HLF(m)) from the cooling degree days (CDD(m)) and heating degree days (HDD(m)) according to the equations: 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:
