Abstract

Claims (32)

1 . A method for augmenting a building model, comprising:

receiving a first building model associated with at least a portion of a building and having a first format;

receiving a second building model associated with the portion of the building and having a second format, wherein the second building model comprises a graph data structure including nodes representing entities of the building and edges representing operating relationships between the entities, the first format different from the graph data structure;

comparing the first building model to the second building model to identify building equipment of the building represented in the first building model that is not represented by a node in the second building model; and

updating the second building model to include the node representing the building equipment and an edge representing an operating relationship indicating a functional dependency between the building equipment and another entity of the building, the functional dependency indicating at least one of (i) an effect of operating the building equipment on an operational state of the other entity of the building represented by another node of the second building model to which the node representing the building equipment is connected by the edge or (ii) an effect of operating the other entity of the building on an operational state of the building equipment represented by the node to which the other node representing the other entity of the building is connected by the edge.

2 . The method of claim 1 , wherein the first building model is a building information management (BIM) model.

3 . The method of claim 1 , wherein the first format is an industry foundation classes (IFC) file format.

4 . The method of claim 1 , wherein the first format is a first version of a building model and the second format is a second version of the building model and wherein updating the second building model to include the identified building equipment includes updating the second version of the building model with information from the first version of the building model.

5 . The method of claim 1 , wherein the edge representing the operating relationship indicates that the building equipment (i) operates to affect the other entity of the building represented by the other node of the second building model to which the node representing the building equipment is connected by the edge or (ii) is affected by operation of the other entity of the building represented by the other node of the second building model to which the node representing the building equipment is connected by the edge.

6 . The method of claim 1 , wherein updating the second building model includes translating information from the first format of the first building model into the second format of the second building model.

7 . The method of claim 1 , wherein updating the second building model includes adding an identifier from the first building model to the second building model.

8 . The system of claim 1 , wherein the first building model comprises hierarchical data representing the building, and wherein updating the second building model includes generating the node and the edge based on the hierarchical data.

9 . One or more non-transitory computer-readable storage media having instructions stored thereon that, when executed by one or more processors, cause the one or more processors to:

receive a first building model associated with at least a portion of a building and having a first format;

receive a second building model associated with the portion of the building and having a second format, wherein the second building model comprises a graph data structure including nodes representing entities of the building and edges representing operating relationships between the entities, the first format different from the graph data structure;

compare the first building model to the second building model to identify building equipment in the first building model that is not represented by a node in the second building model; and

update the second building model to include the node representing the building equipment and an edge representing an operating relationship indicating a functional dependency between the building equipment and another entity of the building, the functional dependency indicating at least one of (i) an effect of operating the building equipment on an operational state of the other entity of the building represented by another node of the second building model to which the node representing the building equipment is connected by the edge or (ii) an effect of operating the other entity of the building on an operational state of the building equipment represented by the node to which the other node representing the other entity of the building is connected by the edge.

10 . The one or more non-transitory computer-readable storage media of claim 9 , wherein the first building model is a building information management (BIM) model.

11 . The one or more non-transitory computer-readable storage media of claim 9 , wherein the first format is an industry foundation classes (IFC) file format.

12 . The one or more non-transitory computer-readable storage media of claim 9 , wherein the first format is a first version of a building model and the second format is a second version of the building model and wherein updating the second building model to include the identified building equipment includes updating the second version of the building model with information from the first version of the building model.

13 . The one or more non-transitory computer-readable storage media of claim 9 , wherein the edge representing the operating relationship indicates that the building equipment (i) operates to affect the other entity of the building represented by the other node of the second building model to which the node representing the building equipment is connected by the edge or (ii) is affected by operation of the other entity of the building represented by the other node of the second building model to which the node representing the building equipment is connected by the edge.

14 . The one or more non-transitory computer-readable storage media of claim 9 , wherein updating the second building model includes translating information from the first format of the first building model into the second format of the second building model.

15 . The one or more non-transitory computer-readable storage media of claim 9 , wherein updating the second building model includes adding an identifier from the first building model to the second building model.

16 . A system for augmenting a building model comprising a processing circuit including a processor and memory, the memory having instructions stored thereon that, when executed by the processor, cause the processing circuit to:

receive a first building model associated with at least a portion of a building and having a first format;

receive a second building model associated with the portion of the building and having a second format, the second building model comprising operating relationships between entities of the building;

compare the first building model to the second building model to identify building equipment of the building represented in the first building model that is not represented in the second building model; and

update the second building model to include a representation of the building equipment and a representation of an operating relationship indicating a functional dependency between the building equipment and another entity of the building, the functional dependency indicating at least one of (i) an effect of operating the building equipment on an operational state of the other entity of the building represented in the second building model or (ii) an effect of operating the other entity of the building on an operational state of the building equipment, the representation of the building equipment generated to conform to the second format of the second building model.

17 . The system of claim 16 , wherein the second building model is a building information management (BIM) model.

18 . The system of claim 16 , wherein the first format is a first version of a building model and the second format is a second version of the building model and wherein updating the second building model to include the representation of the building equipment includes updating the second version of the building model with information from the first version of the building model.
