Main topics of Smart Settlement Systems encompass the research fields of smart mobility (mobility measurements in the building context, linkage of residential housing locations with regional mobility systems and intermodal/ alternative mobility offers, support of fair and balanced mobility), smart environment (re-densification models, coupling of building land potentials with housing demands, space simulations and resource efficiency), smart energy (further development of energy certificates, total energy demand modelling, holistic energetic solutions and certification of settlements, energy balancing and renewable energies) as well as smart governance (elaboration of new directives and strategies in the context of settlement development, re-densification and refurbishment, integration of public and regional authorities as enablers as well as spatial simulation of new governance measures).
