Due to the large amount of data points in a building control system, a methodology is to be created for the operational management to analyze data automatically and thus to make fault detection easier. Methods are to be developed in order to recognize information about the operation as well as changes in operation from the measured value progressions and to be able to supply them to a later error treatment. By integrating BIM data from the building, corresponding models will be generated to validate the HVAC networks which will be used for analysis.
