Abstract

A computing system for providing a software defined building object to applications of a building management system is shown and described. The computing system includes an interface configured to receive building management system inputs from the building management system. The computing system further includes a memory device. The computing system further includes a processing circuit configured to define a software defined building object and to relate building management system inputs received at the interface to the software defined building object. The processing circuit is configured to store the software defined building object in the memory device and to expose the software defined building object to at least one service accessible by the applications of the building management system.

Claims

1. A computing system for providing a software defined building object to applications of a building management system (BMS), comprising:

an interface configured to receive BMS inputs from the BMS;

a memory device; and

a processing circuit configured to define a software defined building object and to relate BMS inputs received at the interface to the software defined building object;

wherein the processing circuit is further configured to store the software defined building object in the memory device and to expose the software defined building object to at least one service accessible by the applications of the BMS.

2. The computing system of claim 1, wherein the processing circuit is configured to relate BMS inputs from different BMS subsystems to the software defined building object.

3. The computing system of claim 2, wherein the software defined building object is configured to represent a physical building space.

4. The computing system of claim 3, wherein the BMS inputs related to the software defined building object are each associated with control of the physical building space.

5. The computing system of claim 4, wherein the at least one service is configured to affect the energy use associated with the physical building space.

6. The computing system of claim 5, wherein the at least one service affects the energy use associated with the physical building space by providing a changed value or a command to a plurality of building devices associated with the physical building space.

7. The computing system of claim 1, wherein the software defined building object includes attributes and services for a plurality of actual building devices.

8. The computing system of claim 7, wherein the plurality of actual devices are physically separate devices.

9. The computing system of claim 7, wherein the plurality of actual devices are logically separate devices.

10. The computing system of claim 7, wherein the plurality of actual devices include at least two building devices coupled to different BMS subsystems and wherein the at least two building devices operate according to different communications protocols.

11. The computing system of claim 1, wherein the software defined building object is not associated with a single building device.

12. A method for providing a software defined building object to applications of a building management system (BMS), comprising:

creating a software defined building object in a memory device;

mapping a group of building devices or inputs of the BMS to the software defined building object; and

exposing the software defined building object to at least one service accessible by applications associated with the BMS.

13. The method of claim 12, wherein the software defined building object is configured to represent a physical building space.

14. The method of claim 13, wherein the group of building devices or inputs mapped to the software defined building object are each related to the physical building space.

15. The method of claim 14, wherein the software defined building object includes an object method configured to allow the applications associated with the BMS to use a single command to affect at least one of the environment of the physical building space and the energy use associated with the physical building space.

16. The method of claim 15, wherein the object method causes a database of historical information to be queried to estimate future energy use associated with the physical building space.

17. The method of claim 12, further comprising:

identifying the group of building devices or inputs of the BMS by analyzing BMS inputs from a plurality of BMS subsystems;

wherein the group of building devices or inputs of the BMS are mapped to the software defined building object as attributes of the software defined building object.

18. The method of claim 12, wherein mapping the group of building devices or inputs of the BMS to the software defined building object comprises:

creating an instance of a building object class; and

assigning attributes of the instantiated building object to paths associated with the group of building devices or inputs of the BMS.

19. The method of claim 18, wherein the at least one service is configured to retrieve the values associated with the building object'"'"'s attributes and to provide the values to one or more of the applications associated with the BMS upon request.

20. The method of claim 19, wherein the at least one service is further configured to receive requests to change the values associated with the building object'"'"'s attributes and wherein the at least one service is further configured to cause the building devices or inputs mapped to the attributes to change values or states.
