Abstract

Managing power consumption in a user space that includes user devices and motion detectors includes monitoring user presence within the space including: monitoring the user devices for user activity, where user activity indicates user presence within the space; and monitoring the motion detectors for user movement, where user movement indicates user presence within the space; if the user devices and motion detectors indicate no user presence within the space, setting one or more environmental control devices to a reduced power consumption state; and if the user devices and motion detectors indicate user presence within the space, setting the one or more environmental control devices to operate in a user-present power consumption state.

Claims

1. A method of managing power consumption in a user space, the space comprising one or more user devices and one or more motion detectors, the method comprising:

monitoring user presence within the space including;

monitoring the user devices for user activity, wherein user activity indicates user presence within the space; and

monitoring the motion detectors for user movement, wherein user movement indicates user presence within the space;

if the user devices and motion detectors indicate no user presence within the space, setting one or more environmental control devices to a reduced power consumption state; and

if the user devices and motion detectors indicate user presence within the space, setting the one or more environmental control devices to operate in a user-present power consumption state.

2. The method of claim 1 wherein monitoring user device activity further comprises monitoring user input device activity of one or more computing devices.

3. The method of claim 1 wherein monitoring the user devices for user activity further comprises receiving, from each user device periodically during user activity of the user device, a device activity signal.

4. The method of claim 1 wherein monitoring the motion detectors for user movement further comprises receiving, from each motion detection device during detection of user movement by the motion detection device, a motion activity signal.

5. The method of claim 1 wherein:

monitoring the user devices for user activity further comprises receiving, from each user device periodically during user activity of the user device, a device activity signal;

monitoring the motion detectors for user movement further comprises receiving, from each motion detection device during detection of user movement by the motion detection device, a motion activity signal; and

setting one or more environmental control devices to a reduced power consumption state further comprises sending a predefined control signal to the environmental control devices upon the loss of the device activity signal and the motion activity signal.

6. The method of claim 1 wherein:

the environmental control devices comprise a light fixture controller and a thermostat, the light fixture controller configured to control power transmission to light fixtures, the thermostat controlling operation of an HVAC (Heating, Ventilation, and Air Conditioning) system; and

setting one or more environmental control devices to a reduced power consumption state further comprises signaling the light fixture controller to remove power from light fixtures and signaling the thermostat to set a predefined control temperature so as to reduce operation of the HVAC system.

7. An apparatus for managing power consumption in a user space, the space comprising one or more user devices and one or more motion detectors, the apparatus comprising a computer processor, a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions that, when executed, cause the apparatus to carry out the steps of:

monitoring user presence within the space including;

monitoring the user devices for user activity, wherein user activity indicates user presence within the space; and

monitoring the motion detectors for user movement, wherein user movement indicates user presence within the space;

if the user devices and motion detectors indicate no user presence within the space, setting one or more environmental control devices to a reduced power consumption state; and

if the user devices and motion detectors indicate user presence within the space, setting the one or more environmental control devices to operate in a user-present power consumption state.

8. The apparatus of claim 7 wherein monitoring user device activity further comprises monitoring user input device activity of one or more computing devices.

9. The apparatus of claim 7 wherein monitoring the user devices for user activity further comprises receiving, from each user device periodically during user activity of the user device, a device activity signal.

10. The apparatus of claim 7 wherein monitoring the motion detectors for user movement further comprises receiving, from each motion detection device during detection of user movement by the motion detection device, a motion activity signal.

11. The apparatus of claim 7 wherein:

monitoring the user devices for user activity further comprises receiving, from each user device periodically during user activity of the user device, a device activity signal;

monitoring the motion detectors for user movement further comprises receiving, from each motion detection device during detection of user movement by the motion detection device, a motion activity signal; and

setting one or more environmental control devices to a reduced power consumption state further comprises sending a predefined control signal to the environmental control devices upon the loss of the device activity signal and the motion activity signal.

12. The apparatus of claim 7 wherein:

the environmental control devices comprise a light fixture controller and a thermostat, the light fixture controller configured to control power transmission to light fixtures, the thermostat controlling operation of an HVAC (Heating, Ventilation, and Air Conditioning) system; and

setting one or more environmental control devices to a reduced power consumption state further comprises signaling the light fixture controller to remove power from light fixtures and signaling the thermostat to set a predefined control temperature so as to reduce operation of the HVAC system.

13. A computer program product for managing power consumption in a user space, the space comprising one or more user devices and one or more motion detectors, the computer program product disposed upon a computer readable medium, the computer program product comprising computer program instructions that, when executed, cause a computer to carry out the steps of:

monitoring user presence within the space including;

monitoring the user devices for user activity, wherein user activity indicates user presence within the space; and

monitoring the motion detectors for user movement, wherein user movement indicates user presence within the space;

if the user devices and motion detectors indicate no user presence within the space, setting one or more environmental control devices to a reduced power consumption state; and

if the user devices and motion detectors indicate user presence within the space, setting the one or more environmental control devices to operate in a user-present power consumption state.

14. The computer program product of claim 13 wherein monitoring user device activity further comprises monitoring user input device activity of one or more computing devices.

15. The computer program product of claim 13 wherein monitoring the user devices for user activity further comprises receiving, from each user device periodically during user activity of the user device, a device activity signal.

16. The computer program product of claim 13 wherein monitoring the motion detectors for user movement further comprises receiving, from each motion detection device during detection of user movement by the motion detection device, a motion activity signal.

17. The computer program product of claim 13 wherein:

monitoring the user devices for user activity further comprises receiving, from each user device periodically during user activity of the user device, a device activity signal;

monitoring the motion detectors for user movement further comprises receiving, from each motion detection device during detection of user movement by the motion detection device, a motion activity signal; and
