1. A method for aligning HVAC consumption with renewable power production with the aid of a digital computer, comprising the steps of:
obtaining time series net load for a time period during which HVAC load for a building will be shifted, an on-site renewable resource power production system connected to the building, the time period comprising regular intervals;
setting time series total load to equal the time series net load plus time series renewable resource power production data;
estimating time series non-HVAC load during the time period;
finding existing time series HVAC load using the time series non-HVAC load and the time series total load;
selecting an HVAC load shifting strategy comprising moving HVAC consumption to match the renewable resource power production, the HVAC shifting strategy subject to one or more conditions;
constructing modified time series net load to match the selected HVAC load shifting strategy subject to operational constraints on the HVAC load;
modeling a change in a size of the on-site renewable resource power production system;
modeling a change in the HVAC load shifting strategy based on the modeled size change;
finding modified time series HVAC load using the time series non-HVAC load, the modified time series net load, and the time series renewable resource production data;
finding time series change in HVAC load using the modified time series HVAC load and the existing time series HVAC load;
iteratively constructing time series change in indoor temperature for the time period as a function of the time series change in HVAC load and the thermal mass, thermal conductivity, and HVAC efficiency for the building; and
evaluating whether the modified time series HVAC load meets the operational constraints and that the conditions associated with the indoor temperature are satisfied, wherein the steps are performed by a suitably programmed computer and an HVAC system of the building is operated based on the HVAC load shifting strategy upon the evaluation the operational constraints and the conditions being met.
