Abstract: A building cooling system includes one or more cooling devices operable to affect an indoor air temperature of a building and a system management circuit. The system management circuit is configured to obtain an objective function that includes a power consumption term and a comfort term, perform an optimization of the objective function over a time horizon to determine values of the cooling capacity of the cooling devices where each value of the cooling capacity corresponds to a time step of the time horizon, and control the cooling devices based on the values of the cooling capacity of the cooling devices. The comfort term of the objective function a difference between a prediction of the indoor air temperature of the building and a temperature setpoint for the building, while the power consumption term is a function of the power consumption of the one or more cooling devices.

Abstract: The techniques described herein provide systems and methods for controlling climate characteristics in a building. The control system of a climate management system may calculate a default airflow rate for each zone in the building based on a minimum permitted airflow rate of climate control equipment, a maximum permitted airflow rate of the climate control equipment, and the number of zones serviced by the climate control equipment. The control system may also adjust the default airflow rate for a zone to a customized airflow rate based on a user input. The control system may adjust the default airflow rate to the customized airflow rate if the customized airflow rate is greater than or equal to the minimum permitted airflow rate. The control system may adjust the default airflow rate to the minimum permitted airflow rate if the customized airflow rate is less than the minimum permitted airflow rate.

Abstract: A universal gateway device includes a first network interface circuit and a second network interface circuit. The first network interface circuit is utilized to communicate over a first network associated with an Internet of Things (IoT) management system utilizing a first communications protocol. The second network interface circuit is utilized to communicate over a second network associated with an IoT device utilizing a second communications protocol that is different from the first communications protocol. The first network interface circuit generates a virtual device representation of the IoT device on the first network. The virtual device representation is utilized to communicate data from the IoT device over the first network utilizing the first communications protocol.

Abstract: The present disclosure includes systems and methods for pre-programming a thermostat such that operational parameters of the thermostat may be selected by an installer during installation based at least in part on a location of the thermostat. For example, a thermostat communicatively coupled to conditioned air equipment may include location determination logic configured to determine a location of the thermostat with respect to a building for which the conditioned air equipment operates. The thermostat also includes conditioned air equipment control logic comprising a plurality of sets of static location-based temperature control algorithms. Each set of the static location-based temperature control algorithms corresponds to a location of the thermostat with respect to the building. The conditioned air equipment control logic is configured to control operation of the conditioned air equipment using a set of the static location-based temperature control algorithms that corresponds to the location determined by the location determination logic.

Abstract: A system for monitoring and controlling flow rate of a fluid through a valve, the system including a flow rate sensor configured to measure the flow rate of the fluid through the valve, and a controller in communication with the flow rate sensor. The controller is configured to receive the measured flow rate from the flow rate sensor and determine if the measured flow rate is equal to a predetermined flow rate value. In response to determining equality, the controller is configured to determine a minimum valve position threshold (xmin), and determine a minimum flow rate threshold (ymin) corresponding to xmin. The controller is further configured to calculate a corrected flow rate (ŷf) using xmin, ymin, and an indication of valve position (v). Additionally, the controller is configured to control a valve operation using the corrected flow rate (ŷf).

Abstract: A thermostat for a conditioned space includes a sensor that measures a value of a performance variable of the conditioned space, a user interface that receives a setpoint value from a user and displays information to the user, and a controller. The controller receives values of the performance variable from the sensor over a time period, stores the values of the performance variable, receives the setpoint value from the user interface, and determines a value of a manipulated variable based on the setpoint value and the values of the performance variable. The controller is configured to adjust an operation of HVAC equipment that affect the conditioned space based on the value of the manipulated variable. The controller is configured to determine a smoothed value of the performance variable based on the values of the performance variable and cause the user interface to display the smoothed value.

Abstract: A building cooling system includes a controller and a cooling device operable to affect indoor air temperature of a building. The controller is configured to obtain a cost function that characterizes a cost of operating the cooling device over a future time period, obtain a dataset relating to the building, determine a current state of the building by applying the dataset to a neural network, select a temperature bound associated with the current state, augment the cost function to include a penalty term that increases the cost when the indoor air temperature violates the temperature bound, and determine a temperature setpoint for each of a plurality of time steps in the future time period. The temperature setpoints achieve a target value of the cost function over the future time period. The controller is configured to control the cooling device to drive the indoor air temperature towards the temperature setpoint.

Abstract: The present disclosure includes techniques that enable a conditioned air system to automatically restore functionality and/or to operate at reduced functionality when a fault is detected, for example, to facilitate reducing likelihood that continuing operation with the fault present will decrease lifespan of the conditioned air system. To facilitate improving operation of the conditioned air system when a fault is present, the control system of the conditioned air system may utilize substitute sensor data and/or adjust its control algorithm. In this manner, the control system may facilitate improving operational reliability and/or availability of the conditioned air system, for example, by adaptively adjusting its operation to enable the conditioned air system to continue operating even when a fault is present, while reducing likelihood that the continued operation will reduce lifespan of the conditioned air system.

Abstract: A building energy system includes HVAC equipment, green energy generation, a battery, and a predictive controller. The HVAC equipment provide heating or cooling for a building. The green energy generation collect green energy from a green energy source. The battery stores electric energy including at least a portion of the green energy provided by the green energy generation and grid energy purchased from an energy grid and discharges the stored electric energy for use in powering the HVAC equipment. The predictive controller generates a constraint that defines a total energy consumption of the HVAC equipment at each time step of an optimization period as a summation of multiple source-specific energy components and optimizes the predictive cost function subject to the constraint to determine values for each of the source-specific energy components at each time step of the optimization period.
