Building management system with space graphs

A method for a building system, the method comprising:

• receiving, by a processing circuit, building data from one or more building data sources;
• generating, by the processing circuit, a plurality of relationships between a plurality of entities based on the building data, wherein the plurality of relationships comprises a pair of relationships between a first entity and a second entity of the plurality of entities representing two different types of relationships, wherein the pair of relationships comprises a first relationship between the first entity and the second entity and a second relationship between the second entity and the first entity;
• and
• updating, by the processing circuit, a space graph by causing the space graph to store a plurality of nodes representing the plurality of entities and a plurality of edges between the plurality of nodes representing the plurality of relationships, wherein the space graph is a graph data structure.

A building management system for operating a building and managing building information, the building management system comprising one or more memory devices configured to store instructions thereon;

• and
• one or more processors configured to execute the instructions to:
• receive building data from one or more building data sources;
• generate a plurality of relationships between a plurality of entities based on the building data, wherein the plurality of relationships comprises a pair of relationships between a first entity and a second entity of the plurality of entities representing two different types of relationships, wherein the pair of relationships comprises a first relationship between the first entity and the second entity and a second relationship between the second entity and the first entity;
• update a space graph by causing the space graph to store a plurality of nodes representing the plurality of entities and a plurality of edges between the plurality of nodes representing the plurality of relationships, wherein the space graph is a graph data structure;
• ingest data values of the building data into the space graph, the data values associated with the plurality of entities;
• and
• perform one or more operations with the space graph based on both the plurality of relationships of the plurality of entities and the ingested data values.

An information management system comprising a processing circuit configured to:

• receive building data from one or more building data sources;
• generate a plurality of relationships between a plurality of entities based on the building data, wherein the plurality of relationships comprises a pair of relationships between a first entity and a second entity of the plurality of entities representing two different types of relationships, wherein the pair of relationships comprises a first relationship between the first entity and the second entity and a second relationship between the second entity and the first entity;
• and
• generate or update a digital twin of a building by causing the digital twin to indicate the plurality of entities and the plurality of relationships.
