Summary
Due to the increasing climate crisis and the stricter national and international climate protection targets, new neighbourhoods should be designed to be climate-neutral in the future. However, climate-neutrality can have a significant influence on urban design; energy planning must therefore take place in parallel with urban land use planning and thus earlier than before, and corresponding energy components must be included in the development plan. The challenges involved were determined in the EnStadt:Pfaff project, in which the preparation of the development plan for the Pfaff quarter was scientifically accompanied with the aim of achieving climate neutrality. As a concrete result, a guiding principle, a solar and green roof obligation and parking space regulations with mobility stations were included in the development plan. From the experience gained, it can be concluded that traditional urban land use planning in Germany must be further developed to enable the conception of climate-neutral neighbourhoods. This concerns a holistic and more balanced reflection of the objectives in the assessment processes, which are becoming increasingly complex. Therefore, it is proposed to describe the objectives in a guiding principle based on sustainability criteria in a holistic way. Further development is also required with regard to the urban land use planning processes, which should be designed more cooperatively in the future. Finally, suggestions are made as to how the municipalities themselves can change their urban land use planning processes and how the legislator can improve the framework conditions.
