Energy management system
View Patent ↗Feedback is received from a plurality of devices. External data is also received. Statistical patterns of the plurality of devices are determined based on the feedback. A policy is determined based on the statistical patterns, the feedback, and the external data. The policy may include a set of rules dictating the operation of each of the plurality of devices and reducing energy consumption at the plurality of devices. Control data based on the policy is transmitted to the plurality of devices. The control data may be operative to transform the operation of the plurality of devices according to the set of rules.
1. An energy management system for use in a facility, comprising:
a plurality of lighting devices, each of the lighting devices comprising a communications device and an occupancy sensor; and
a controller coupled to the plurality of lighting devices over a network, the controller operative to
receive feedback data from the plurality of lighting devices, through the communications device,
determine statistical patterns of the plurality of lighting devices based on the feedback data, which includes device-independent data detected by the occupancy sensors,
measure ambient light in the facility,
determine a policy based on the statistical patterns, the measured ambient light, and the feedback data, the policy comprising a set of rules dictating the operation of each of the plurality of lighting devices,
provide a suggestion based on the policy,
receive a response to the suggestion, and
transmit control data based on the response to the suggestion, the control data used to change an amount of lighting associated with the plurality of lighting devices, wherein the control data reduces usage of lighting in areas of higher ambient light and increases usage of lighting in areas of lower ambient light.
2. The energy management system of claim 1 , wherein the occupancy sensors monitor and track movement of people into, in, and from the facility.
3. The energy management system of claim 2 , further determining the most visited areas of the facility.
4. The energy management system of claim 1 , further comprising:
receiving energy accounting data;
determining a cost of utilities from a power supplier using the energy accounting data; and
adjusting a usage of renewable energy based on the cost of the utilities.
5. The energy management system of claim 1 , wherein the suggestion comprises an option to accept the suggestion, an option to reject the suggestion, or an option to modify the suggestion.
6. The energy management system of claim 4 , wherein the energy accounting data accounts for an amount of renewable energy in a renewable energy storage.
7. The energy management system of claim 4 , wherein the energy accounting data comprises carbon credit data.
8. The energy management system of claim 7 , wherein the carbon credit data comprises a carbon credit policy that specifies a carbon emissions limit above which a penalty is enforced and a carbon footprint.
