Classification: CPC F  G | IPC F  G

Claim 16:
17. A method for monitoring a Heating-Ventilating-Air-Conditioning (HVAC) system installed at an enclosed facility, the method comprising the steps of:
installing an HVAC system at the facility, wherein the HVAC system is operated with electric power from an external power source with operational costs based on a predetermined power demand profile set by the external power source;
providing a control unit connected with the HVAC system for receiving internal microclimate data for temperature and humidity pertinent to environmental conditions inside the facility and external data for temperature and humidity pertinent to on-site, microclimate, meteorological conditions immediately outside the facility;
comparing the internal microclimate data with the external microclimate data, wherein the control unit establishes an actual demand signal based on the microclimate data comparison;
determining a first cost curve for the actual demand signal over a predetermined time period, determining a second cost curve for the predetermined power demand profile and determining a cost differential between the first and second cost curves, the cost differential representing an area representative of relative costs for operating the HVAC system; and
controlling a throttle with the control unit, wherein the control unit controls the throttle according to the actual demand signal to regulate power supplied to operate the HVAC system according to the actual demand signal and to divert an excess amount power determined based on the cost differential to a storage battery for future use and while a cost of energy is low.
