Patent ID: 7894943

Claim:
A building heating/cooling system energy optimization method for a building having at least one air handling unit (AHU) and a heating/cooling system including a plurality of components comprising at least a condenser unit, a heating unit and a cooling unit, said method comprising the steps: providing a mathematical model of the heating/cooling system including at least an efficiency profile of the components of the heating/cooling system; obtaining real-time weather information including at least outside temperature and outside humidity; reading an input water temperature (IWT) of said heating/cooling system, an output water temperature (OWT) of said heating/cooling system, a supply air temperature (SA) output to the building via the at least one air handling unit and an ambient air temperature (AA) within the building; periodically transferring said real-time weather information, said IWT, said OWT, said SA and said AA, collectively real-time data, to an optimization engine, said optimization engine operative to analyze said real-time data in coordination with said mathematical model by assigning at least three selected values in a range surrounding and including current values of each of said IWT, said OWT and said SA for each of said IWT, said OWT and said SA and calculating the efficiency profile of the components of the heating/cooling system for each of said at least three selected values for each of said IWT, said OWT and said SA, then selecting those values calculated to provide a highest efficiency profile of the components of the heating/cooling system by cooperatively optimizing each of said IWT, said OWT and said SA; and periodically resetting each of said IWT, said OWT and said SA to said values selected by said optimization engine to generally maximize the efficiency profile of the components of the heating/cooling system.
