Abstract

A method (300) of managing energy consumption associated with premises includes firstly generating (302) and storing an initial energy profile (304) of the premises. The profile (304) includes information characterizing the premises, such as occupancy patterns, function of the premises, geographical location, installed appliances (108), and so forth. An expected energy usage (308) associated with the premises is computed over a predetermined time period based upon the information in the initial energy profile (304). Actual energy usage (312) associated with the premises is then recorded over the predetermined time period and the energy profile (304) is adaptively updated based upon the recorded energy usage (312). The energy profile (304) and the actual energy usage (312) are used to manage energy consumption associated with the premises. An installable system (100) and apparatus (102) for implementing the method at premises are also provided.

Claims

1. A method of managing energy consumption associated with a premises, including the steps of:

generating and storing an initial energy profile of the premises, the profile including information inferred by physical characterizing the premises;

computing an expected energy usage associated with the premises over a predetermined time period based upon the information in the initial energy profile;

recording actual energy usage associated with the premises over the predetermined time period;

adaptively updating the initial energy profile based upon comparison of the recorded energy usage, the expected energy usage and the inferred characterizing of the premises; and

using the adaptively updated energy profile and the actual energy usage to manage energy consumption associated with the premises.

2. The method of claim 1 wherein information in the energy profile includes a variety of characteristic information relating to the geographic location of the premises, the size, content and nature of use of the premises, and typical times of use of the premises.

3. The method of claim 1 wherein the profile includes information relating to the function of the premises.

4. The method of claim 3, wherein the information relating to function is used to infer typical characteristics of energy consumption associated with the premises.

5. The method of claim 1 wherein the profile includes information relating to associated appliances, including one or more of the number, type and characteristics of energy appliances installed at the premises.

6. The method of claim 1 wherein information relating to appliances associated with the premises is inferred based upon information in the profile along with actual energy usage, and adaptively incorporated into the energy profile.

7. The method of claim 1 which further includes performing real-time monitoring of internal and/or external temperatures of the premises to enable the setting and/or efficiency of heating and cooling appliances within the premises to be evaluated, thereby providing opportunities to manage ongoing energy consumption associated with such appliances by adjustment to operational settings, including times of operation and/or set temperatures.

8. The method of claim 1 wherein the steps of recording actual energy usage, and adaptively updating the energy profile, are repeated over one or more subsequent time periods.

9. The method of claim 8 wherein the rate and/or magnitude of updates are reduced over time as compared with the initial update cycle.

10. The method of claim 1 wherein managing energy consumption includes detecting abnormal events, and generating corresponding alerts.

11. The method of claim 1 wherein managing energy consumption includes activating and deactivating appliances.

12. The method of claim 11 wherein a step of activating or deactivating an appliance includes requesting confirmation by a human operator, and may further include the manual and/or automated operation of the appliance via a remote interface.

13. The method of claim 1 wherein managing energy consumption includes identifying and/or predicting potential energy-saving strategies, including a reduction in standby power consumption.

14. The method of claim 1 which includes alerting a human operator in the event that one or more appliances may have inadvertently been left on.

15. The method of claim 1 wherein the step of managing energy consumption includes:

sending to an operator information regarding energy consumption and/or alerts relating to abnormal events via email, SMS messaging, messages transmitted to a specific remote software application, and/or other means;

receiving from the operator an instruction for operation of one or more appliances associated with the premises via email, SMS messaging, messages transmitted using a specific remote software application, or other means; and

controlling said one or more appliances in accordance with the operator instructions.

16. A system for managing energy consumption associated with premises, the system including:

a metering unit which is configured to provide time-dependent readings of energy usage associated with the premises; and

a microprocessor-based controller including an interface for communicating with the metering unit, and having a data store containing information representing an initial energy profile of the premises, wherein the initial expected energy profile includes information inferred by physical characterizing the premises,

wherein the controller is configured to;

compute an expected energy usage associated with the premises over a predetermined time period based upon the information in the energy profile;

receive from the metering units, and record in the data store, actual energy usage associated with the premises over the predetermined time period;

adaptively update the information representing the initial energy profile of the premises, based upon comparison of the recorded energy usage, the expected energy usage and the inferred characterizing of the premises; and

use the adaptively updated information representing the energy profile of the premises, and the actual recorded energy usage, to manage energy consumption associated with the premises.

17. The system of claim 16, further including user interface apparatus having a graphical display and appropriate control inputs enabling an operator to review information representative of energy consumption associated with the premises, and to direct operation of the controller and/or appliances installed at the premises.

18. The system of claim 16, further including additional communications interfaces, including one or more of an SMS or other messaging interface, to enable the delivery of real-time alerts, warnings or updates to a human operator.

19. The system of claim 16, including appliances associated with the premises which are operable by the controller via one or more appliance communications systems.

20. A computer-implemented apparatus for managing energy consumption associated with premises, the apparatus including:

a microprocessor;

at least one memory device, operatively coupled to the microprocessor;

at least one input/output peripheral interface, operatively coupled to the microprocessor and configured to communicate with a metering unit which provides time-dependent reading of energy usage associated with the premises,

wherein the at least one memory device includes a data store containing information representing an initial energy profile of the premises, wherein the initial energy profile includes information inferred by physical characterizing the premises, and

wherein the at least one memory device further contains executable instruction code which, when executed by the microprocessor, implements a method including the steps of;

computing an expected energy usage associated with the premises over a predetermined time period based upon the information representing the initial energy profile of the premises;

receiving from the metering unit, and recording in the data store, actual energy usage associated with the premises over the predetermined time period;

adaptively updating the information representing the energy profile of the premises based upon comparison of the recorded energy usage, the energy usage and the inferred characterizing of the premises; and
