Challenges of Technical Energy Systems of Buildings:

  • Buildings account for about 40 % of final energy demand in industrialized countries.
  • Operation of buildings contributes by about 30 % to CO2 emissions.
  • People spend most of their time in buildings; thus indoor comfort has a major impact on our health and well-being.
  • European Union and German government aim at achieving an almost “climate neutral” building sector in 2050.
  • In the future, new buildings have to achieve an almost zero energy standard in the EU (public buildings from 2019 on; non-public buildings from 2021).

 

Tasks for Sustainable Systems Engineers:

  • Reduce the energy footprint of buildings in different climatic zones through efficient energy conversion chains and „Low-Ex“ systems
  • Design sustainable energy supply systems for buildings including the use of renewable energy sources
  • Apply the concept of sector coupling on the building level.
  • Integrate future requirements like indoor comfort in building design
  • Drive holistic approach regarding sustainability of buildings
