Abstract: An environmental control system of a building including a first building device operable to affect environmental conditions of a zone of the building by providing a first input to the zone. The system includes a second building device operable to independently affect a subset of the environmental conditions by providing a second input to the zone and further includes a controller including a processing circuit. The processing circuit is configured to perform an optimization to generate control decisions for the building devices. The optimization is performed subject to constraints for the environmental conditions and uses a predictive model that predicts an effect of the control decisions on the environmental conditions. The processing circuit is configured to operate the building devices in accordance with the control decisions.

An actuator drive device is driven by an actuator motor and is coupled to the valve for driving the valve between multiple positions. The system further includes a differential pressure sensor configured to measure a differential pressure across the valve and a controller that is communicably coupled with the differential pressure sensor and the motor. The controller is configured to receive a flow rate setpoint and the differential pressure measurement, determine an estimated flow rate based on the differential pressure measurement, determine an actuator position setpoint using the flow rate setpoint and the estimated flow rate, and operate the motor to drive the drive device to the actuator position setpoint.

Abstract: A space controller includes processors and non-transitory computer-readable media storing instructions that, when executed by the processors, cause the processors to perform operations. The operations include obtaining a power consumption model that defines a change in power consumption of HVAC equipment that operate to provide heating or cooling to a space as a function of a change in temperature setpoint for the space and model parameters that represent thermal properties of the space. The operations include estimating values of the model parameters based on training data including values of the power consumption of the HVAC equipment, the temperature setpoint for the space, and outdoor air temperature at multiple times within a training period. The operations include using the power consumption model and the values of the model parameters to predict a change in the power consumption of the HVAC equipment expected to result from a change in the temperature setpoint.

Abstract: A method for visualizing and managing entities and connections between entities based on a graphical user interface (GUI) node editor includes constructing an entity datablock, wherein the entity datablock is a data structure describing an entity and comprises entity descriptive information, an entity category, an entity name, entity relationships, and an entity identifier. The method includes establishing the entity relationships as bi-directional relationships, wherein the bi-directional relationships link two disparate entities. The method further includes representing the entity datablock as a node and the bi-directional relationships as lines connecting two nodes, wherein the node comprises at least one of the entity descriptive information, the entity category, or the entity name.
