Abstract: A processor is configured to receive an electronic item comprising an object signature and corresponding to a building infrastructure item, such as space, equipment, monitoring point, etc. The processor is configured to validate the object signature, including determining, based on the object signature, a data source associated with the building infrastructure item. For each of the plurality of data objects from the data source, where each data object corresponds to a particular installation of the building infrastructure item, the processor is configured to determine a signature suffix associated with a current version and/or current configuration of the particular installation. The processor is configured to generate a validated object signature, including appending the signature suffix to the object signature. The processor is configured to identify a target computing system and transmit the validated object signature to the target computing system (e.g., in the form of a representational state transfer (REST) message.).

Abstract: A building system of a building includes one or more memory devices configured to store instructions that, when executed by one or more processors, cause the one or more processors to receive meter data from a meter of the building, the meter data indicating energy usage of a plurality of tenants of the building collectively. The instructions cause the one or more processors to receive variable air volume (VAV) airflow data of a plurality of VAV units indicating environmental conditioning of a plurality of tenant areas associated with the plurality of tenants and determine the energy usage of each of the plurality of tenants individually based on the meter data and the VAV airflow data.
