The Bonn-Rhein-Sieg University buildings can be found in Sankt Augustin and Rheinbach. The Social Security Management degree offered in Hennef has been taught in the rooms of the Berufsgenossenschaftlichen Akademie (Trade Associations Academy) since 2003. This degree is offered in co-operation with the Hauptverband der gewerblichen Berufsgenossenschaften (the General League of Trade Associations).
The buildings in Sankt Augustin and Rheinbach are new - the University first moved into them between 1999 and 2000. The building in Sankt Augustin, which also contains the administrative offices, is regarded as a particularly energetic and environmentally friendly construction. Both campuses are currently being extended.
