Building system with data model including bidirectional relationships

A method of building management comprising:

• causing, by one or more processing circuits, a storage device to store a data model comprising a plurality of data entities representing a plurality of entities of a building and a plurality of relationships, wherein the plurality of data entities comprise a first data entity and a second data entity, wherein the plurality of relationships comprise a first relationship between the first data entity and the second data entity and a second relationship between the second data entity and the first data entity, wherein the first relationship is semantically related to the second relationship;
• retrieving, by the one or more processing circuits, at least a portion of the data model from the storage device;
• generating, by the one or more processing circuits, derived building data based on at least the portion of the data model;
• and
• ingesting, by the one or more processing circuits, the derived building data into the data model.

One or more storage devices configured to store instructions thereon that, when executed by one or more processing circuits, cause the one or more processing circuits:

• cause a storage device to store a data model comprising a plurality of data entities representing a plurality of entities of a building and a plurality of relationships, wherein the plurality of data entities comprise a first data entity and a second data entity, wherein the plurality of relationships comprise a first relationship between the first data entity and the second data entity and a second relationship between the second data entity and the first data entity, wherein the first relationship is semantically related to the second relationship;
• retrieve at least a portion of the data model from the storage device;
• retrieve building data from the data model;
• generate derived building data based on the building data retrieved from the data model and a contextual representation of the building, wherein the portion of the data model retrieved from the storage device is the contextual representation of the building;
• and
• ingest the derived building data into the data model.
