Device descriptions play an important role in the design and commissioning of modern building automation systems and help\r\nreducing the design time and costs.However, all established device descriptions are specialized for certain purposes and suffer from\r\nseveral weaknesses. This hinders a further design automation, which is strongly needed for the more and more complex building\r\nautomation systems. To overcome these problems, this paper presents novel Ontology-based Device Descriptions (ODDs) along\r\nwith a layered ontology architecture, a specific ontology view approach with virtual properties, a generic access interface, a triple\r\nstore-based database backend, and a generic search mask GUI with underlying query generation algorithm. It enables a formal,\r\nunified, and extensible specification of building automation devices, ensures their comparability, and facilitates a computerenabled\r\nretrieval, selection, and interoperability evaluation, which is essential for an automated design. The scalability of the\r\napproach to several ten thousand devices is demonstrated.
