Abstract: A system for a building management system simulation includes one or more processors and memory. The memory includes instructions stored thereon, that when executed by the one or more processors, cause the one or more processors to generate a space agent representing a space in a building, the space agent to maintain an environmental condition of the space based on an optimization state of the space, generate an equipment agent representing a device that serves the space, and register the space agent and the equipment agent to a space communication channel associated with the space. The space agent communicates with the equipment agent over the space communication channel.

Abstract: A building system includes one or more storage devices having instructions stored thereon that, when executed by one or more processors, cause the one or more processors to receive an unstructured user question from a user device of a user and query a graph database based on the unstructured user question to extract context associated with the unstructured user question from contextual information of a building stored by the graph database, wherein the graph database stores the contextual information of the building through nodes and edges between the nodes, wherein the nodes represent equipment, spaces, people, and events associated building and the edges represent relationships between the equipment, spaces, people, and events. The instructions further cause the one or more processors to retrieve data from one or more data sources based on the context and compose a presentation based on the retrieved data.

Abstract: An actuator in a HVAC system includes a mechanical transducer, a processing circuit, a wireless transceiver, and a power circuit. The processing circuit includes a processor and memory and is configured to operate the mechanical transducer according to a control program stored in the memory. The wireless transceiver is configured to facilitate bidirectional wireless data communications between the processing circuit and an external device. The power circuit is configured to draw power from a wireless signal received via the wireless transceiver and power the processing circuit and the wireless transceiver using the drawn power. The processing circuit is configured to use the power drawn from the wireless signal to wirelessly transmit data stored in the memory of the actuator to the external device via the wireless transceiver, wirelessly receive data from the external device via the wireless transceiver, and store the data received from the external device in the memory.

Abstract: A heating, ventilation, and/or air conditioning (HVAC) system includes a compressor, a fan, an inverter configured to drive operation of the compressor, and a controller communicatively coupled to the fan and the inverter. The controller includes a tangible, non-transitory, computer-readable medium with computer-executable instructions that, when executed by processor circuitry, are configured to cause the processor circuitry to determine an operating parameter of the fan in response to an interruption in receiving communication signals from the inverter and operate the fan based on the operating parameter during the interruption.
