Abstract: The present disclosure relates to a control box configured to connect to heating, ventilation, and/or air conditioning (HVAC) equipment. The control box includes an outer housing and a divider wall located within the outer housing that separates a high voltage section of the control box and a low voltage section of the control box. The control box also includes a controller disposed within the low voltage section and first wiring extending from the controller to the HVAC equipment via a first passage formed in the outer housing. Additionally, the control box includes second wiring extending between the low voltage section and the high voltage section via a second passage formed in the divider wall. Furthermore, the control box includes a cover configured to engage the outer housing to cover the low voltage section while exposing the high voltage section.

Abstract: A method for controlling a variable refrigerant flow (VRF) system includes applying a time window to sensor data associated with the VRF system, the sensor data including input data points and having a first resolution, wherein applying the time window to the sensor data isolates a subset of the input data points; applying a timing weight to one or more input data points in the subset of the input data points to generate corrected data points having a second resolution higher than the first resolution; creating a virtual sensor and mapping the corrected data points to an output of the virtual sensor; and controlling the VRF system based on an output of the virtual sensor. The use of virtual sensors with a higher resolution than corresponding physical sensors in this manner allows for existing physical sensors to be used while improving performance of the VRF system.

Abstract: A method includes defining a plurality of monitored spaces. For each of at least a subset of the plurality of monitored spaces, the method includes associating a set of laboratory equipment with the monitored space, calculating an equipment utilization score for the monitored space based on resource consumption data for the set of laboratory equipment, calculating an occupancy utilization score for the monitored space based on occupant tracking data for the monitored space, and calculating a combined utilization score based on the equipment utilization score and the occupancy utilization score. The method also includes providing a graphical user interface comprising the combined utilization scores for the subset of the plurality of monitored spaces.

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.

Abstract: A building management system includes a controller for one or more devices of the building management system and a system manager communicably coupled to the controller. The controller includes a priority array for a point object managed by the controller. The priority array includes a plurality of commands for the point object and defines a priority of each command. The system manager is configured to retrieve the priority array from the controller, generate a user interface identifying the plurality of commands in the priority array and the priority of each command, receive a new command from a user, and update the user interface to include a preview of the priority array indicating how the priority array would change if the new command were applied to the priority array.

Abstract: A controller for equipment that operates to affect a variable state or condition of a building including one or more processors and non-transitory computer-readable media storing instructions that, when executed by the processors, cause the processors to perform operations. The operations include generating a new predictive model using training data associated with one or more durations selected from a time period and selected to satisfy a set of criteria. The predictive model models system dynamics of the building during the time period. The operations include storing the new predictive model in a database including predictive models that model the system dynamics of the building and include comparing performance of the new predictive model and the predictive models stored by the database to select a particular predictive model for controlling the equipment. The operations include using the particular predictive model to generate and provide control signals to the equipment.
