Abstract: A building management system includes HVAC equipment operable to affect an indoor air temperature of a building, a system manager configured to obtain a cost function that characterizes a cost of operating the HVAC equipment, 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 building management system also includes a controller configured to operate the HVAC equipment to drive the indoor air temperature towards the temperature setpoint.

Abstract: A controller for operating building equipment of a building including processors and non-transitory computer-readable media storing instructions that, when executed by the processors, cause the processors to perform operations including obtaining a first setpoint trajectory from a cloud computation system. The first setpoint trajectory includes setpoints for the building equipment or for a space of the building. The setpoints correspond to time steps of an optimization period. The operations include determining whether a connection between the controller and the cloud computation system is active or inactive at a time step of the optimization period and determining an active setpoint for the time step of the optimization period using either the first or second setpoint trajectory based on whether the connection between the controller and the cloud computation system is active or inactive at the time step. The operations include operating the building equipment based on the active setpoint.

Abstract: A heating, ventilation, or air conditioning (HVAC) system for a building includes one or more processing circuits having one or more processors and one or more non-transitory computer-readable media containing program instructions. When executed by the one or more processors, the instructions cause the one or more processors to perform operations including providing an optimization function for operating HVAC equipment over a future time period including a plurality of time steps and using the optimization function to generate a time series of temperature setpoints for the plurality of time steps in the future time period. The time series of temperature setpoints achieve a target value of the optimization function over the future time period. The operations include operating the HVAC equipment to drive indoor air temperature toward a first temperature setpoint of the time series of temperature setpoints for a first time step of the plurality of time steps.
