Claim 18:
19. A system for time-series based aligning HVAC consumption with renewable power production with the aid of a digital computer, comprising the steps of:
a computer comprising at least one processor and a memory interfaced to the processor, the processor configured to:
obtain 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;
set time series total load to equal the time series net load plus time series renewable resource power production data;
estimate time series non-HVAC load during the time period;
find existing time series HVAC load using the time series non-HVAC load and the time series total load;
select 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;
construct modified time series net load to match the selected HVAC load shifting strategy subject to operational constraints on the HVAC load;
find 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;
find time series change in HVAC load using the modified time series HVAC load and the existing time series HVAC load;

iteratively construct 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, comprising iteratively constructing the time series change in indoor temperature starting at the beginning of the time period, where each change in indoor temperature calculated applies to the next time interval in the time period following the change in HVAC load; and
evaluate whether the modified time series HVAC load meets the operational constraints and that the conditions associated with the indoor temperature are satisfied, wherein 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.
