Abstract: A computing system for providing a software defined building object to applications of a building management system is shown and described. The computing system includes an interface configured to receive building management system inputs from the building management system. The computing system further includes a memory device. The computing system further includes a processing circuit configured to define a software defined building object and to relate building management system inputs received at the interface to the software defined building object. The processing circuit is configured to store the software defined building object in the memory device and to expose the software defined building object to at least one service accessible by the applications of the building management system.
