Classification: CPC F  G | IPC F  G

Claim 9:
10. An on-site climate control monitor for maximizing operational cost efficiencies at an enclosed facility, the monitor comprising:
an HVAC system installed 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;
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;
a summing network connected to the control unit for comparing the internal microclimate data with the external microclimate data, wherein based on the comparison, the control unit establishes an actual demand signal for power to operate the HVAC system, wherein the control unit is configured to determine a first cost curve for the actual demand signal over a predetermined time period and to determine a second cost curve for the predetermined power demand profile, and further to determine 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
a throttle to regulate power supplied to the HVAC system according to the actual demand signal while diverting excess power to a battery based on the cost differential and when a cost of energy is low.
