Abstract: A system includes processing circuitry programmed to perform operations. The operations include determining whether a first sensor is available at a chiller. The first sensor includes a temperature sensor or a pressure sensor of the chiller. The operations include, responsive to determining that the first sensor is unavailable, determining an estimated value for the first sensor based on measurements from available sensors of the chiller (where the available sensors include at least one of an available temperature sensor or an available pressure sensor of the chiller), determining a plurality of enthalpy points using the estimated value for the first sensor and the measurements from the available sensors, and determining an efficiency of the chiller based on the plurality of enthalpy points. The operations also include affecting an operation of the chiller based on the efficiency.

Abstract: A system for automatic application of fault detection and diagnostics (FDD) rules within a building management system (BMS) includes a memory having instructions stored thereon and a processor configured to execute the instructions. The processor, in executing the instructions, may retrieve from a plurality of BMS devices, a first BMS device having at least one attribute. The processor may identify, from a plurality of FDD rules based on the at least one attribute, an FDD rule associated with the at least one attribute. The processor may apply the FDD rule to the data point of the first BMS device corresponding to the at least one attribute. The processor may, responsive to determining a second BMS device from the plurality of BMS devices shares the at least one attribute, automatically apply the FDD rule to the second BMS device.
