Abstract: A method of selecting building equipment for serving a building including determining one or more hard constraints and one or more soft constraints for the building equipment, determining a plurality of possible combinations of building equipment to serve the building, determining a first set of possible combinations that meet all of the hard constraints and all of the soft constraints, determining a second set of possible combinations that meet all of the hard constraints and do not meet all of the soft constraints, selecting a combination of building equipment to serve the building from the first set of possible combinations if the first set contains a possible combination, or selecting a combination of building equipment to serve the building from the second set of possible combinations if the first set contains no possible combinations, and serving the building using the selected combination of building equipment.

Abstract: A central plant includes a plurality of subplants and circuitry. The circuitry is configured to obtain an expert model associated with a first subplant of the plurality of subplants. The expert model includes a map of values of independent variables to one or more dependent variables. The circuitry is also configured to receive input data indicating input values for the independent variables and estimate outputs values for the one or more dependent variables associated with the input variables by determining a spatial relationship between the input data and the expert model, reducing the expert model to a reduced model based on the spatial relationship, and performing an interpolation using the reduced model to generate the output values for the one or more dependent variables. The circuitry is also configured to initiate an automated action using the output values.

Abstract: A central plant includes a plurality of subplants including a chiller configured to output supply water at a supply water temperature, a sensor configured obtain a measurement of the supply water temperature, and a control system. The control system is configured to calculate an additional load factor based on the measurement of the supply water temperature and a supply water temperature setpoint, obtain an actual load for the chiller, calculate an effective load based on the additional load factor and the actual load, generate load allocations for the plurality of subplants based on the effective load, and control the plurality of subplants to operate in accordance with the load allocations.
