Abstract: Sensorized commercial buildings are a rich target for building a new class of applications that improve operational and energy efficiency of building operations that take into account human activities. Such applications, however, rarely experience widespread adoption due to the lack of a common descriptive schema that would enable porting these applications and systems to different buildings. Our demo presents Brick [4], a uniform schema for representing metadata in buildings. Our schema defines a concrete ontology for sensors, subsystems and relationships among them, which enables portable applications. Using a web application, we will demonstrate real buildings that have been mapped to the Brick schema, and show application queries that extracts relevant metadata from these buildings. The attendees would be able to create example buildings and write their own queries.

Abstract: A method for predicting time periods in which faults are likely to occur for a piece of building equipment. The method includes receiving a plurality of measurements for one or more points that are associated with a piece of building equipment, the plurality of measurements measured during a first time period; executing a machine learning model using the plurality of measurements as an input to generate fault data for a plurality of time periods subsequent to the first time period; selecting a second time period from the plurality of time periods responsive to an assessment of the fault data for the plurality of time periods indicating a fault will likely occur in the piece of building equipment during the second time period of the plurality of time periods; and performing an automated action responsive to the selection of the second time period.

Abstract: A system for user interaction with a building automation system (BAS). The system includes a user device configured to accept vocal inputs and produce audio outputs, and a server in communication with the user device and a BAS controller. The server is configured to translate a vocal input to input text, and determine and store a conversation context based on the input text. The server is further configured to determine a desired output corresponding to the input text. Additionally, the server is configured to receive, from the BAS controller, BAS data corresponding to the desired output, and generate at least one audio output from the BAS data. The user device outputs the at least one audio output, and the server is configured to apply the conversation context to a subsequent vocal input.

Abstract: A building automation system (BAS) is configured to support a variety of different natural language processing (NLP) service providers with minimal or no redesign effort. The BAS includes an event handler configured to receive an external request from a service provider. The external request is associated with a voice input uttered by a user. The BAS further includes an abstraction layer configured to receive the external request from the event handler and generate an internal request based on the external request. The BAS further includes an intent processor configured to receive the internal request from the abstraction layer and an intent handler in communication with the intent processor and configured to perform an action in accordance with the internal request.

Abstract: A smart circuit breaker is configured for installation within a panel assembly. The smart circuit breaker includes a breaker device positioned between a power source and a subcircuit, the breaker device having a moveable contactor configured to change from an open state to a closed state, wherein in the closed state power flows from the power source to the subcircuit via a power line, and wherein in the open state power does not flow from the power source to the subcircuit. The smart circuit breaker further includes a power meter configured to measure a power characteristic of the subcircuit. The smart circuit breaker further includes a processing circuit configured to receive a power characteristic measurement from the power meter, the processing circuit having a communications interface configured to communicate power consumption data to an external device, the power consumption data based on the power characteristic.
