Building management smart entity creation and maintenance using time series data

A method comprising:

• generating, by a processing circuit, a timeseries for a data point of a building device;
• accessing, by the processing circuit, a digital twin data structure representing contextual information of a building and operational data of the building, the digital twin data structure comprising a plurality of entities representing a plurality of elements of the building and a plurality of relationships between the plurality of entities representing relationships between the plurality of elements, wherein the digital twin data structure includes a graph that links the plurality of entities with the plurality of relationships;
• identifying, by the processing circuit, based on the digital twin data structure, an entity of the plurality of entities associated with the data point of the building device;
• and
• storing, by the processing circuit, at least a portion of the timeseries, or a link to at least the portion of the timeseries, in the entity.

A non-transitory storage medium storing instructions thereon that, when executed by one or more processing circuits, cause the one or more processing circuits to:

• generate a timeseries for a data point of a building device;
• access a digital twin data structure representing contextual information of a building and operational data of the building, the digital twin data structure comprising a plurality of entities representing a plurality of elements of the building and a plurality of relationships between the plurality of entities representing relationships between the plurality of elements, wherein the digital twin data structure includes a graph that links the plurality of entities with the plurality of relationships;
• identify, based on the digital twin data structure, an entity of the plurality of entities associated with the data point of the building device, wherein a device entity representing the building device is related to the entity by a relationship of the plurality of relationships;
• and
• store at least a portion of the timeseries, or a link to at least the portion of the timeseries, in the entity.
