Building data platform with an enrichment loop

A method comprising:

• receiving, by a processing circuit, from an event source, an event, the event comprises data and a timestamp;
• performing, by the processing circuit, an enrichment pipeline, the enrichment pipeline:
• identifying, by the processing circuit, first contextual data describing the event in a digital twin, the digital twin comprising a virtual representation of a building;
• enriching, by the processing circuit, the event with the first contextual data;
• and
• outputting, by the processing circuit, to a consuming system, the enriched event, the consuming system generating an output event based on the enriched event;
• and
• feeding, by the processing circuit, the output event back into an input of the enrichment pipeline, and the enrichment pipeline:
• identifying, by the processing circuit, second contextual data describing the output event in the digital twin;
• enriching, by the processing circuit, the output event with the second contextual data;
• and
• outputting, by the processing circuit, to the consuming system or another consuming system, the enriched output event.

A building system comprising:

• one or more memory devices having instructions thereon;
• and
• one or more processors configured to execute the instructions causing the one or more processors to:
• receive an event from an event source, the event comprising data and a timestamp;
• identify first contextual data describing the event in a digital twin, the digital twin including a building graph providing a virtual representation of a building, the building graph comprising:
• a plurality of nodes representing a plurality of entities of the building, wherein at least a portion of the plurality of nodes represent the first contextual data, second contextual data, the event source, and a consuming system;
• and
• a plurality of edges between the plurality of nodes, wherein the plurality of edges represent relationships between the plurality of entities of the building;
• enrich the event with the first contextual data;
• provide the enriched event to the consuming system, the consuming system generating an output event based on the enriched event;
• identify the second contextual data describing the output event in the digital twin;
• enrich the output event with the second contextual data;
• and
• provide the enriched output event to the consuming system or another consuming system.
