Abstract: A heating, ventilation, and air conditioning (HVAC) system for a building includes a plurality of actuation devices operable to affect one or more variables in the building, a plurality of sensors configured to measure the variables affected by the actuation devices, and a controller. The controller is configured to operate the actuation devices to affect one or more of the measured variables by providing an actuation signal to the actuation devices and to receive sensor response signals from the sensors. The sensor response signals indicate an effect of the actuation signal on the measured variables. For each of the sensor response signals, the controller is configured to calculate a similarity metric indicating a similarity between the sensor response signal and the actuation signal. The controller is configured to automatically establish a device pairing including one of the actuation devices and one of the sensors based on the similarity metrics.

Abstract: A flow control device is configured to control fluid flow in an HVAC system. The flow control device includes a valve, an actuator configured to open and close the valve, and one or more sensors. The flow control device further includes a fault detection and correction agent configured to receive data from the one or more sensors, analyze the data according to a set of rules, and detect whether one or more faults have occurred. In response to detecting a fault, the fault detection and correction agent is configured to either operate the actuator to open or close the valve or initiate a corrective action to be taken by another device in the HVAC system.

Abstract: A building energy management includes building equipment, one or more data platform services, a timeseries database, and an energy management application. The building equipment operate to monitor and control a variable and provide raw data samples of a data point associated with the variable. The timeseries database stores a plurality of timeseries associated with the data point. The plurality of timeseries include a timeseries of the raw data samples and the one or more optimized data timeseries generated by the data platform services based on the raw data timeseries. The energy management application generates an ad hoc dashboard including a widget and associates the widget with the data point. The widget displays a graphical visualization of the plurality of timeseries associated with the data point and includes interactive user interface options for switching between the plurality of timeseries associated with the data point.

Abstract: A building management system includes an entity database and an identity management service. The entity database 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. The 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 in response to the first and second identity attributes matching the stored identity attributes of the object entity.

Abstract: A method for classifying an occluded object includes receiving, by one or more processing circuits, an image of the object that is partially occluded by a foreign object and classifying, by the one or more processing circuits, the object of the image into one of one or more classes of interest via an artificial neural network (ANN) by determining a plurality of neuron activations of neurons of the ANN for one or more foreign classes and the one or more classes of interest, subtracting one or more of the neuron activations of the one or more foreign classes from the neuron activations of the one or more classes of interest, wherein the foreign object belongs to one of the one or more foreign classes, and classifying the object of the image into the one of the one or more classes of interest based on the subtracting.

Abstract: A building management system (BMS) includes building equipment, a data collector, a sample aggregator, and an application. The building equipment is operable to monitor and control a variable in the BMS and to provide raw data samples of the variable. The data collector is configured to collect the raw data samples from the building equipment and generate a raw data timeseries including a plurality of the raw data samples. The sample aggregator is configured to automatically generate a data rollup timeseries including a plurality of aggregated data samples. The aggregated data samples are generated by aggregating the raw data samples as the raw data samples are collected from the building equipment. Both timeseries are stored in a timeseries database. The application is configured to retrieve the raw data timeseries and the data rollup timeseries from the timeseries database in response to a request for timeseries data associated with the variable.

Abstract: A building management system includes one or more computer-readable storage media having instructions stored thereon that, when executed by one or more processors, cause the one or more processors to receive a plurality of threats, the plurality of threats comprising a first threat and a second threat, the first threat and the second threat affecting a risk score of an asset and determine whether the first threat is correlated with the second threat. The instructions cause the one or more processors to determine a value of the risk score to be a first value in response to a determination that the first threat is correlated with the second threat and determine the value of the risk score to be a second value in response to a determination that the first threat is not correlated with the second threat.

Abstract: A heating ventilation and air conditioning (HVAC) system for a building space includes an HVAC device including a processing circuit. The processing circuit is configured to generate an encrypted dynamic key based on a manifest stored on the device. The manifest includes a set of entitlements for the HVAC device based on relationships between the HVAC device and entities. The processing circuit is further configured to transmit the stored manifest to an authentication server by sending the encrypted dynamic key to the authentication server and receive an updated manifest from the authentication server based on the encrypted dynamic key. The processing circuit is further configured to send a payload request to the authentication server based on the updated manifest, the payload request including a software update request.
