A building system including one or more memory devices configured to store instructions thereon, the instructions causing one or more processors to receive building data from one or more building data sources, identify, based on the building data, an indirect relationship between a first entity and a second entity of a space graph, the indirect relationship caused by a control algorithm of the space graph, update the space graph with the indirect relationship by causing the space graph to include an indirect relationship edge between a first node of nodes representing the first entity and a second node of the nodes representing the second entity, update the control algorithm of the space graph based on the indirect relationship edge, and operate one or more pieces of building equipment based on the updated control algorithm.
