Claim 7:
8. A method for building heating-modification-based gross energy load modification modeling with the aid of a digital computer, comprising:
obtaining by a computer, the computer comprising a processor and memory within which code for execution by the processor is stored, a gross energy load associated with a building based on electricity provided to the building by a power utility and energy provided to the building by an on-site renewable energy system;
estimating by the computer an overall thermal performance of the building by conducting an empirical test comprising remotely controlling a heating source inside the building;
modeling by the computer an effect of one or more changes to the overall thermal performance of the building on the gross energy load comprising determining a characteristic of a further heating source needed to supply heat for space heating the building with the changed overall thermal performance, determining the characteristic of the further heating source comprising:
obtaining a maximum amount of energy consumed in a single day during a time period for space heating in the building;
determining at least one mathematical relationship between heating losses in the building before the changes are performed and heating losses estimated to be in the building after the changes are performed, wherein the heating losses comprise envelope heating losses and duct heating losses and the estimated heating losses comprise estimated envelope heating losses and estimated duct heating losses, determining the at least one mathematical relationship comprising determining a ratio of the envelope heating losses and the estimated envelope heating losses and a ratio of the duct heating losses and the estimated duct losses and determining a product of the ratios, wherein the at least one mathematical relationship comprises the product of the ratios:
using the at least one mathematical relationship and the maximum amount of energy to determine a further maximum amount of the energy that would be needed in the building in a single day after the changes are performed;

determining by the computer the characteristic based on the further maximum amount of the energy needed in the building after the changes are performed; and
determining by the computer a characteristic of a further renewable energy system needed to power the further heating source using the characteristic of the heating source.
