Bauhaus2050: Energy efficient refurbishment of city quarters reducing CO2 emissions allowing for heritage listed building stock in Weimar
Future city quarter development in the discourse of energy efficiency and resource depletion requires further development of planning methodologies in terms of planning processes and instruments. The energy efficiency potential of large existing building stock will be analysed for building skin retrofit, energy supply systems updates and feasible synergies. By shifting the focus from the single building to the city quarter, the overall CO2 emission reduction of the cluster can be obtained.
The campus of the Bauhaus Universität Weimar will be analysed as a case study for larger building stocks to determine the energy efficiency potential of building skin retrofits, energy supply systems updates and feasible synergies. The campus of the university is located within the city centre with a significant share of heritage-listed building. Furthermore, five of the 32 buildings are not only heritage protected; moreover they are part of the UNESCO World Heritage and hence, building envelope measurements are simply not applicable. The building stock of the surrounding quarter is characterised by mixed use of varying building typologies and ages; the ground floor often houses retail or crafts; the upper floors mainly residential units. In combination with the university functions, the quarter focusses on the preservation of a liveable, mixed-use neighbourhood that allows for coexistence of living and working as a key parameter to sustainable cities. Instead of evaluation the potential of a single building, extending the perimeter to the quarter will help to identify synergies that only exist in building ensembles of varying functions and their occupancy profiles and load profiles respectively. Furthermore, new developments on brownfields might be able to support CO2 neutral local energy production to reduce the overall CO2 emission balance.
