Abstract: One implementation of the present disclosure is a controller for a variable refrigerant flow system. The controller includes processors and memory storing instructions that, when executed by the processors, cause the processors to perform operations including identifying zones within a structure, generating zone groupings defining zone groups and specifying which of the zones are grouped together to form each of the zone groups, generating metric of success values corresponding to the zone groupings and indicating a control feasibility of a corresponding zone grouping, selecting a zone grouping based on the metric of success values, and using the selected zone grouping to operate equipment of the variable refrigerant flow system to provide heating or cooling to the zones.

Abstract: A method for dynamically updating a building management system (BMS) control platform for a building includes receiving, by the BMS control platform, a context, wherein the context includes metadata defining a data model for the building and equipment of the building, wherein the metadata describes the data model with a common modeling language (CML). The method further includes implementing, by the BMS control platform, the data model of the context via the CML, wherein the BMS control platform implements the data model during the runtime of the BMS control platform and does not require redeployment of the BMS control platform, and controlling, by the BMS control platform, the equipment of the building based on the implemented data model to control an environmental condition of the building.

Abstract: A method for controlling equipment includes grouping a plurality of granular assets to form one or more general assets and generating models of the general assets based on the granular assets that form the general assets. Each model corresponds to a general asset and defines a relationship between resources produced by the general asset and resources consumed by the general asset. The method includes performing a first control process using the models of the general assets to determine a first allocation of resources among the general assets. The first allocation defines amounts of the resources to be consumed, produced, or stored by each of the general assets. The method includes operating the equipment to consume, produce, or store the resources in accordance with the first allocation.

Abstract: A method for controlling an energy production and distribution system includes identifying sources that supply input resources, subplants that produce output resources using the input resources, and sinks that consume the output resources. The method includes obtaining a cost function including a cost of producing the output resources and generating a transit time constraint that requires the input resources be sent from the sources to the subplants at a first departure time that occurs before a first arrival time at which the input resources are predicted to be used by the subplants. The method includes solving an optimization problem to determine an amount of the output resources to produce at each of multiple time steps within a time period. Solving the optimization problem includes performing an optimization of the cost function subject to the transit time constraint.

Abstract: A controller for a plurality of heating, ventilation, or air conditioning (HVAC) devices includes a processing circuit that includes one or more processors and memory. The controller detects a change in condition that affects an operating status of a first HVAC device of the plurality of HVAC devices. The controller uses schematic relationships between the plurality of HVAC devices to determine a reduced subset of the plurality of HVAC devices for which operating parameters are to be generated based on the operating status of the first HVAC device. The controller generates operating parameters for the reduced subset of the plurality of HVAC devices and operates the plurality of HVAC devices using the operating parameters.

Abstract: A fiber optic flow sensor includes a fiber optic cable, a light emitter, an optical power meter, and a processing circuit. The fiber optic cable allows light to enter a first end of the fiber optic cable, reflect off a second end of the fiber optic cable and exit the fiber optic cable through the first end. The fiber optic cable is at least partially exposed to fluid flow at the second end. The light emitter emits light at an input power into the first end of the fiber optic cable. The optical power meter measures an output power of the light exiting the fiber optic cable at the first end. The processing circuit calculates a flow rate of the flow of fluid based on the input power of light entering the fiber optic cable and the output power of light exiting the first end of the fiber optic cable.
