Fault detection and diagnostics (FDD) methods can contribute reducing energy losses by early detecting faulty operations of HVAC systems and thus supporting corrective actions. However, Model-based FDD methods require a vast amount of data for set-up, such as time-series data from sensors and actuators and semantic data documenting technical properties of the supervised systems. This paper presents the conceptual data model for a database, in which we aim to collect, describe, and classify semantic information about operational faults of HVAC systems, the buildings, the HVAC systems themselves including their data points (sensors/actuators). The main objective is to provide a semantically unified structure for the documentation of faults in HVAC systems to enable developers and engineers training, testing and comparing FDD methods.
