1. A method for visualizing a building model of a building, comprising:
retrieving a global identifier identifying a digital representation of a first building asset of the building, the global identifier retrieved from the digital representation of the building, wherein the digital representation of the first building asset and the digital representation of the building are both formatted as a first file format having a first file extension, the digital representation of the building comprising a graph data structure, the digital representation of the first building asset represented as a node identified by the global identifier in the graph data structure;
querying one or more databases of a plurality of graphical representations of building assets of the building model using the retrieved global identifier to identify a first graphical representation of the plurality of graphical representations corresponding to the first building asset, wherein the querying comprises ingesting the global identifier retrieved from the digital representation of the building and using the global identifier to identify the first graphical representation, the plurality of graphical representations of the building assets from the building model stored in the one or more databases are formatted as a second file format having a second file extension different from the first file format having the first file extension;
retrieving the first graphical representation of the first building asset from the one or more databases;
rendering the retrieved first graphical representation on a display device;
receiving a second building model of the building;
comparing the second building model with the digital representation of the building to identify building assets represented in both the second building model and the digital representation of the building; and
updating the second building model to include global identifiers of the building assets represented in both the second building model and the digital representation, wherein the second building model is stored as a subsequent version of the digital representation of the building.
