Device descriptions play an important role in the design and commissioning of modern building automation systems and help reducing the design time and costs. However all established device descriptions are specialized for certain purposes and suffer from several weaknesses. This hinders a further design automation which is strongly needed for the more and more complex building automation systems. To overcome these problems this paper presents novel Ontology-based Device Descriptions ODDs along with a layered ontology architecture a specific ontology view approach with virtual properties a generic access interface a triple store-based database backend and a generic search mask GUI with underlying query generation algorithm. It enables a formal unified and extensible specification of building automation devices ensures their comparability and facilitates a computer-enabled retrieval selection and interoperability evaluation which is essential for an automated design. The scalability of the approach to several ten thousand devices is demonstrated. 1. Introduction Modern and complex building automation systems consist of hundreds to several thousands of field and .
