Building automation system with fault analysis and component procurement

A method, comprising:

• receiving data corresponding to a first condition of a piece of building equipment within a building;
• determining, based on the data, an actual or anticipated fault state of the piece of building equipment;
• storing a graph data structure including a plurality of digital twins representing a plurality of entities and a plurality of relationships between the plurality of digital twins, and wherein the graph data structure represents at least one of a space, person, component, or event, wherein at least one digital twin of the plurality of digital twins includes historical maintenance data associated with the piece of building equipment, a utilization of the piece of building equipment, and a utilization of a space of the building;
• retrieving first context information corresponding to the utilization of the piece of building equipment and second context information corresponding to the utilization of the space of the building from the plurality of digital twins;
• assigning a fault priority level to the piece of building equipment based on the first context information corresponding to the utilization of the piece of building equipment and the second context information corresponding to the utilization of the space of building;
• and
• implementing a service action for the piece of building equipment based on the fault priority level, by determining an availability of a replacement building device by traversing at least a portion of the plurality of digital twins and the plurality of relationships within the graph data structure to identify one digital twin of the plurality of digital twins storing inventory data within the graph data structure and generating data to procure the replacement building device.

A building management system (BMS), comprising:

• one or more processing circuits and one or more computer readable storage media, the one or more computer readable storage media having instructions stored thereon that, when executed by the one or more processing circuits, cause the one or more processing circuits to:
• receive data corresponding to a first condition of a piece of building equipment within a building;
• determine, based on the data, an actual or anticipated fault state of the piece of building equipment;
• store a graph data structure including a plurality of digital twins representing a plurality of entities and a plurality of relationships between the plurality of digital twins, and wherein the graph data structure represents at least one of a space, person, component, or event, wherein at least one digital twin of the plurality of digital twins includes historical maintenance data associated with the piece of building equipment, a utilization of the piece of building equipment, and a utilization of a space of the building;
• retrieve first context information corresponding to the utilization of the piece of building equipment and second context information corresponding to the utilization of the space of the building from the plurality of digital twins;
• assign a fault priority level to the piece of building equipment based on the first context information corresponding to the utilization of the piece of building equipment and the second context information corresponding to the utilization of the space of building;
• and
• implement a service action for the piece of building equipment based on the fault priority level, by determining an availability of a replacement building device by traversing at least a portion of the plurality of digital twins and the plurality of relationships within the graph data structure to identify one digital twin of the plurality of digital twins storing inventory data within the graph data structure and generating data to procure the replacement building device.
