    Abstract: A controller for a building control system includes processors and memory storing instructions that, when executed by the processors, cause the processors to perform operations including identifying zones within a building, analyzing data associated with the zones, and generating zone groupings based on the data associated with the zones. Each of the zone groupings define zone groups and specify which of the zones are grouped together to form each of the zone groups. The operations also include identifying a particular zone grouping from zone groupings based on the data associated with zones and using the particular zone grouping to generate control signals to operate equipment of the building control system to provide heating or cooling to the zones.

    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 central plant control system configured to serve one or more energy loads in a building comprises equipment configured to consume, produce, or store one or more resources including electricity, water, natural gas, steam, hot thermal energy, cold thermal energy, or electrical energy. The central plant control system further comprises an asset allocator configured to receive an input model that describes a physical layout of the equipment of the central plant and create a net list that defines connections between the equipment of the central plant using the input model. The asset allocator is further configured to discover one or more systems of interconnected equipment and one or more groups of equipment using the net list, formulate an optimization problem for the central plant using the systems and groups of equipment, and operate the equipment of the central plant according to the optimization problem.

    Abstract: A building management system (BMS) includes a controller that monitors performance values for a controlled process during a first time period relative to initial outlier detection limits and generates new outlier detection limits for the controlled process in response to a detected change in the controlled process during the first time period. The controller monitors the performance values relative to the new outlier detection limits during a second time period to detect outliers during the second time period. The controller calculates a confidence difference for an estimated confidence parameter based on a number of outliers detected using the new outlier detection limits during the second time period. The controller adjusts the new outlier detection limits in response to the confidence difference dropping below a threshold value.

    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.
