This paper presents a methodology for model-based fault detection and diagnosis underpinned by modelica models and using a qualitative approach to diagnosis, which has been applied to diagnosis of an air handling unit based on data recorded by a building management system.The main steps from model development to component diagnosis are discussed and illustrated using a heating coil component.
