Abstract
An apparatus for detecting component faults monitored by a building management system (BMS), including an automatic fault detection (AFD) element, coupled to the BMS, that monitors samples generated by the BMS indicating operative states of the components, and that employs the data samples to determine if one or more of the components are faulty. The AFD element includes a run time modeling element and a fault detection algorithm element. The modeling element employs the samples as inputs to execute one or more fault algorithms retrieved from a system model, and generates outputs that indicate if the one or more of the components are faulty. The algorithm element is coupled to the system model, and employs normalized/standardized datapoints representing the samples to select the one or more fault algorithms for storage in the system model, where the one or more fault algorithms are selected from a standard fault algorithm data base.
