Abstract

Accessing an energy management policy for a plurality of devices is described, wherein the devices are coupled with a first structure. The energy usage of the devices is monitored. An energy usage rule and energy usage is then compared. The energy management policy and energy usage is also compared. Based on the comparing, an instruction is generated to modify an energy usage profile of said device to correlate with the energy usage rule associated with the devices and the energy management policy, thereby enabling efficient energy management.

Claims

1. A method of controlling a temperature of an enclosure, comprising:

wirelessly receiving, at a thermostat associated with the enclosure, at least one setpoint temperature from a user via an energy management device, the setpoint temperature indicating a desired temperature of the enclosure;

operating the thermostat in accordance with the setpoint temperature;

monitoring energy consumption associated with the thermostat;

comparing the monitored energy consumption to an energy usage profile;

based on the comparing, determining at least one adjustment to the operation of the thermostat that will reduce energy consumption associated with the thermostat as compared to the energy consumption associated with operating the thermostat in accordance with the setpoint temperature, wherein the at least one adjustment is determined based at least in part on a weather outside of the enclosure; and

operating the thermostat in accordance with the at least one adjustment.

2. The method of claim 1, further comprising:

receiving a command from a remote server to conserve energy; and

operating the thermostat in accordance with the command.

3. The method of claim 2, wherein the command includes increasing the thermostat'"'"'s setpoint temperature when an outside temperature is expected to be high.

4. The method of claim 2, wherein the command includes reducing the thermostat'"'"'s setpoint temperature when an outside temperature is expected to be low.

5. The method of claim 1, wherein operating the thermostat in accordance with the setpoint temperature includes taking into consideration a user'"'"'s subjective perception of temperature.

6. The method of claim 5, wherein taking into consideration a user'"'"'s subject perception of temperature includes querying the user as to whether they are hot or cold.

7. The method of claim 1, further comprising:

determining an address of the enclosure,
