Abstract: A method for verifying and running a script for a building management system of a building includes receiving, by the building management system, the script, wherein the script indicates one or more operations to be performed with one or more data points of a data model of the building, determining, by the building management system, whether there is unit cohesion within the received script, wherein the unit cohesion indicates that a result value of executing the script with the one or more data points include units that match desired units, and determining, by the building management system, the result value by executing the script with the one or more data points in response to determining that there is unit cohesion.

Abstract: A building management system includes building equipment operable to affect a variable state or condition of a building and a control system configured to receive a user input indicating a model form. The model form includes a plurality of matrices having a plurality of elements defined in terms of a plurality of parameters. The control system is configured to parse the model form to generate a sequence of machine-executable steps for determining a value of each of the plurality of elements based on a set of potential parameter values, identify a system model by executing the sequence of machine-executable steps to generate a set of parameter values for the plurality of parameters, generate a graphical user interface that illustrates a fit between predictions of the identified system model and behavior of the variable state or condition of the building, and control the building equipment using the identified system model.

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.

Abstract: A method for automatically commissioning and operating an HVAC system to serve energy loads of a building site is shown. The method includes querying site information describing the building site to identify physical equipment and relationships between the physical equipment. The method further includes constructing an asset allocator model, the asset allocator model indicating connections between the physical equipment and resources produced or consumed by the physical equipment. The method further includes generating a mapping between points of the physical equipment at the building site and corresponding variables of the asset allocator model. The method further includes using the asset allocator model to generate values of one or more control variables of the asset allocator model. The method further includes adjusting an operation of the physical equipment by triggering software elements to automatically push updated values of the control variables to corresponding points of the physical equipment.

Abstract: A controller for operating building equipment of a building. The controller includes one or more processors. The controller includes one or more non-transitory computer-readable media storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations. The operations include comparing one or more model parameters of predictive models describing zones of the building to determine one or more zone groups for the building. The operations include generating one or more zone group models corresponding to the one or more zone groups. The operations include operating the building equipment using the one or more zone group models to affect a variable state or condition of the building.

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.
