The future energy concept from the German federal government declares that by 2050, the primary energy requirement should be reduced to 80 %. Achieving this goal requires many local implementations. At teaching and research facilities, a large number of rooms and other spaces are used temporarily. That use usually happens over a predetermined period. The observance of the specific usage period of teaching rooms, in particular of internal teaching rooms, was used to design and implement a future-oriented energy concept for a lecture room. The concept was created to show how technical building services could be used. This work describes our concept’s principle, methodology, and implementation. This concept can also be used for energy optimization in other teaching rooms.
