Abstract

A system to control energy consumption in a building having a plurality of rooms with a wireless data transceiver; an occupancy sensor; a temperature sensor; a processor coupled to the wireless data transceiver, the occupancy sensor and the temperature sensor; and an air register including a motor coupled to the processor, the motor opening or closing one or more air vents in response to sensed motion or room temperature.

Claims

1. A system to control energy consumption in a building having a plurality of rooms, comprising:

a wireless data transceiver;

an occupancy sensor;

a temperature sensor;

a processor coupled to the wireless data transceiver, the occupancy sensor and the temperature sensor; and

an air register including a motor coupled to the processor, the motor opening or closing one or more air vents in response to sensed motion or room temperature.

2. The system of claim 1, wherein the air register is closed when the room is empty.

3. The system of claim 1, comprising a smart meter coupled to the appliance, wherein the smart meter includes bi-directional communication, power measurement and management capability, software-controllable disconnect switch, and communication over low voltage power line.

4. The system of claim 1, comprising a thermostat to set room temperature.

5. The system of claim 4, wherein the thermostat wirelessly communicates with the data transceiver.

6. The system of claim 1, wherein the processor communicates with an online weather service for predicted weather condition.

7. The system of claim 1, wherein the processor pre-charges room temperature in response to a demand response signal or a predetermined pattern.

8. The system of claim 1, wherein the processor minimizes operating cost by shifting energy use to an off-peak period in response to utility pricing that varies energy cost by time of day.

9. The system of claim 1, comprising an energy harvester coupled to the processor.

10. The system of claim 9, wherein the energy harvester comprises a solar cell.

11. The system of claim 1, comprising a heating ventilation air conditioning (HVAC) device coupled to a rechargeable energy reservoir, wherein the reservoir is charged during a utility off-peak period and used to power the HVAC device during a utility peak pricing period.

12. The system of claim 1, comprising a recognizer coupled to the transceiver including one of:

a Hidden Markov Model (HMM) recognizer, a dynamic time warp (DTW) recognizer, a neural network, a fuzzy logic engine, a Bayesian network.

13. The system of claim 1, wherein the occupancy sensor comprises an analyzer to process an RSSI signal from the wireless data transceiver to detect occupancy in the area.

14. The system of claim 1, comprising a light emitting diode coupled to the processor to detect light, wherein the processor determines lighting profiles that incorporate time-based control with occupancy, daylighting, and manual control and wherein the processor integrates time-based lighting control with occupancy sensing control.

15. The system of claim 1, comprising a heater proximal to the air vent.

16. The system of claim 1, comprising an air conditioner or cooler proximal to the air vent.

17. The system of claim 1, comprising a fan proximal to the air vent.
