    Abstract: A computerized method of assigning a building automation system point type to a plurality of unclassified data points is provided. The method includes receiving unclassified data points and attributes for each data point. The method includes receiving classifications for a first subset of the unclassified data points. Each classification associates a data point with a building automation system point type. The method includes generating a term set containing substrings that appear in the attributes. The method includes generating a first matrix describing a frequency that the substrings appear in the attributes. The method includes calculating an indicator of a probability that the presence of the selected substring results in the data point belonging to the selected point type. The method includes assigning a point type to a second subset by finding the substring and potential point type pair having the greatest indication of probability.

    Abstract: A building system for operating a building and managing building information, the building system comprising 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 and generate a space graph based on the building data, wherein the space graph is a graph data structure comprising nodes representing entities and edges between the entities representing relationships between the entities. The instructions cause the one or more processors to ingest data values of the building data into the space graph, the data values associated with the entities, and perform one or more operations with the space graph based on both the relationships of the entities and the ingested data values.

    Abstract: A system for securely communicating information in a building management system (BMS) includes a plurality of HVAC devices communicably coupled via a network each HVAC device storing a copy of an HVAC data chain that includes a plurality of blocks linked sequentially. The plurality of HVAC devices includes a first HVAC device including a processing circuit configured to generate a first block comprising device data and send the block to at least a portion of the plurality of HVAC devices. The processing circuit is configured to receive a second block from one of the plurality of HVAC devices and solve the second block. The processing circuit is further configured to add the solved block to the HVAC data chain of the first HVAC device as the newest block and send the solved block to each of the plurality of HVAC devices.

    Abstract: A heating, ventilation, and air conditioning (HVAC) system for a building includes a plurality of actuation devices, a plurality of sensors, and a controller. The actuation devices receive actuation signals and operate in accordance with the actuation signals to affect one or more variables in the building. The sensors measure the variables affected by the actuation devices and provide sensor response signals including values of the measured variables. The controller generates actuation signal timeseries including samples of the actuation signals and sensor response timeseries including samples of the sensor response signals. The controller applies a discrete cosine transformation (DCT) to each actuation signal timeseries and each sensor response timeseries. Each DCT generates a set of DCT coefficients. The controller identifies a similarity between two or more of the actuation signal timeseries and the sensor response timeseries by comparing the DCT coefficients resulting from the DCTs.

    Abstract: A building management system includes an entity database that stores a plurality of interconnected smart entities. The smart entities include object entities representing a plurality of people or physical devices and data entities representing data associated with the people or physical devices. The smart entities are interconnected by relational objects indicating relationships between the object entities and the data entities. Each of the object entities includes a plurality of stored identity attributes. An identity management service is configured to receive a first identity attribute from a first device within a building, receive a second identity attribute from a second device within the building, compare the first and second identity attributes to the stored identity attributes of an object entity of the plurality of interconnected smart entities, and allow access to at least one of a building space, a device of building equipment, or a computer system.
