A pathogen detection system for a building includes multiple pathogen detectors positioned in the building at different locations. The pathogen detectors are configured to output detection data including a detected presence of a pathogen. The pathogen detection system includes processing circuitry configured to obtain the detection data from the pathogen detectors. The processing circuitry is also configured to determine a responsive action based on the detected presence of the pathogen, and the locations. The responsive action includes a magnitude of effect and a magnitude of locality. The processing circuitry is configured to perform the responsive action or initiate the responsive action.

A sensor in a building HVAC system includes a transducer configured to measure a variable in the building HVAC system and to generate a sensor reading indicating a value of the measured variable. The sensor includes a communications interface configured to provide the sensor reading to a control device in the building HVAC system and a near field communication (NFC) circuit separate from the communications interface. The NFC circuit is configured to facilitate bidirectional NFC data communications between the sensor and a mobile device. The sensor includes a processing circuit having a processor and memory. The processing circuit is configured to wirelessly transmit data stored in the memory of the sensor to the mobile device via the NFC circuit, wirelessly receive data from the mobile device via the NFC circuit, and store the data received from the mobile device in the memory of the sensor.

Systems and methods for configuring and communicating with HVAC devices

A method for controlling building equipment includes generating building data relating to conditions in a building space using a generative artificial intelligence model. The method also includes determining whether the building data correspond to conditions in the building space that comply with one or more regulations or certification standards. The method includes, in response to determining that the building data correspond to conditions in the building space that comply with the one or more regulations or certification standards, using the building data to operate building equipment that serve the building space.

Building system with synthetic data compliance control

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.

A variable air volume (VAV) box includes a fan operable to induce airflow from a building space through the VAV box and discharge the airflow back to the building space, an air cleaning device positioned to clean the airflow through the VAV box before discharging the airflow back to the building space and configured to affect an air quality of the airflow, and a controller configured to operate the fan to modulate the airflow through the VAV box to achieve a target air quality for at least one of the airflow discharged from the VAV box or air within the building space.

Building device with near field communication circuit

A building system for a building including one or more storage devices storing instructions thereon that, when executed by one or more processors, cause the one or more processors to operate one or more pieces of building equipment associated with a building space based on a first operating mode. The instructions cause the one or more processors to receive an indication to update operation of the building space based on an emergency situation and responsive to receiving the indication to update operation of the building space based on the emergency situation, operate the one or more pieces of building equipment based on a second operating mode, wherein the second operating mode defines one or more second parameters for the one or more pieces of building equipment and is adapted to reconfigure the operation of the building space to address or mitigate the emergency situation.

Building system with flexible facility operation

An actuator in a HVAC system includes a motor and a drive device driven by the motor. The drive device is coupled to a movable HVAC component for driving the movable HVAC component between multiple positions. The actuator includes an input connection configured to receive an input signal and a processing circuit coupled to the motor. The processing circuit is configured to determine whether the input signal is an AC voltage signal or a DC voltage signal. The processing circuit is configured to operate the motor using an AC motor control technique in response to determining that the input signal is an AC voltage signal and configured to operate the motor using a DC motor control technique in response to determining that the input signal is a DC voltage signal.

Wireless sensor with near field communication circuit

A valve assembly is provided. The valve assembly includes a valve body having a valve chamber and a plurality of ports into the valve chamber. The plurality of ports include a first port, a second port, and a third port. The first port and the second port are aligned with a common axis and located on opposite sides of the valve chamber. The system further includes a valve member located within the valve chamber. The valve member is a rotatable ball having a fluid passage that extends through the ball and includes an opening at the end of the ball. The fluid passage is substantially oval-shaped when viewed at the opening in a direction parallel to the fluid passage. The valve assembly further includes a valve stem that is coupled to a valve member and has a first end that extends from the valve body.
