Abstract

A building has climate control equipment which controls a temperature at different locations. Different locations may be in different control zones controlled by different control devices. An occupant of a location submits a desired location temperature through a user interface on a computing device to a networked server. Setting of a desired temperature is constrained by energy saving policies and by conditions of surrounding locations. An arbitrator device determines based on constraints a new temperature setting. The new temperature setting is accompanied by an energy saving feedback. The occupants confirms the new setting. A climate control device is instructed to apply a device setting to achieve the new temperature. A climate profile of the occupant is learned from previous temperature settings by the occupant.

Claims

1. A method for determining in a first building with a first location and a second location a first temperature setting of a climate control device enabled to affect the first and the second location, comprising:

a processor enabled to receive from a first user interface via a first soft thermostat embodied in a first instance of a software application allocated to a first user on a first computing device an instruction for a preferred temperature for the first location and the processor enabled to receive from a second user interface via a second soft thermostat embodied in a second instance of the software application allocated to a second user on a second computing device an instruction for a preferred temperature for the second location; and

the processor arbitrating the received preferred temperature settings based on a constraint to set the climate control device to determine a first arbitrated temperature setting as the first temperature setting, wherein the arbitrating is based on an optimization criterion that minimizes a difference between the preferred temperature of the first location and the first arbitrated temperature setting and the preferred temperature of the second location and the first arbitrated temperature setting.

2. The method of claim 1, wherein the constraint is based on an energy policy.

3. The method of claim 1, wherein the constraint is based on an input provided by a facility manager.

4. The method of claim 1, wherein the preferred temperature of the first location is applied by the processor to create a temperature profile of an occupant of the first location.

5. The method of claim 4, wherein the temperature profile of the occupant is accessible through/from a social network.

6. The method of claim 4, wherein a second temperature setting of the climate control device is based on the temperature profile of the occupant.

7. The method of claim 4, further comprising:

the occupant occupying a third location in the first building; and

the processor accessing the temperature profile of the occupant to determine a temperature setting of a climate control device related to the third location.

8. The method of claim 4, wherein the occupant is enabled to change the temperature profile.

9. The method of claim 4, further comprising:

setting a temperature by a system for climate control in a second building by accessing the temperature profile of the occupant through the network.

10. The method of claim 1, wherein the processor determines the first arbitrated temperature setting based on preferred temperatures of at least 5 different locations in the building.

11. The method of claim 1, wherein the processor is part of an existing Building Automation System (BAS).

12. The method of claim 1, wherein the first location is in a first zone in the first building and the constraint is based on a temperature difference between the first location and the second location in the first building.

13. A system to determine in a first building with a first location and a second location a first temperature setting of a climate control device enabled to affect the first and the second location, comprising:

a memory enabled to store data, including instructions;

a processor enabled to execute instructions retrieved from the memory to perform the steps;

receiving from a first user interface via a first soft thermostat embodied in a first instance of a software application allocated to a first user on a first computing device an instruction for a preferred temperature for the first location and the processor enabled to receive from a second user interface via a second soft thermostat embodied in a second instance of the software application allocated to a second user on a second computing device an instruction for a preferred temperature for the second location; and

arbitrating the received preferred temperature settings based on a constraint to set the climate control device to determine a first arbitrated temperature setting as the first temperature setting, wherein the arbitrating is based on an optimization criterion that minimizes a difference between the preferred temperature of the first location and the first arbitrated temperature setting and the preferred temperature of the second location and the first arbitrated temperature setting.

14. The system of claim 13, wherein the preferred temperature of the first location is applied by the processor to create a temperature profile of an occupant of the first location.

15. The system of claim 14, wherein the temperature profile of the occupant is accessible through a social network.

16. The system of claim 14, wherein a second temperature setting of the climate control device is based on the temperature profile of the occupant.

17. The system of claim 13, wherein the processor is part of an existing Building Automation System (BAS).
