Creation of a concept for the energy-efficient renovation of the "Insel" quarter of the city of Lindau

The city of Lindau (B) has set itself the goal of being climate-neutral by 2035. The energy supply – especially the heat supply – plays a central role here. Lindau (B) is characterized above all by the medieval old town on the island and a large number of historic buildings on the mainland. Due to the dense structure and the age of the buildings, the installation of PV systems is often not possible. Nevertheless, a concept is to be developed for the island that will ensure a sustainable energy supply and thus reduce CO2 emissions and significantly and permanently reduce energy costs for citizens.

The concept for energy-efficient urban renovation is primarily intended to identify technical and economic energy-saving potentials as well as the potential of renewable energies in an area-related contiguous area (so-called districts). The planned quarter includes several private, commercial and public buildings as well as the infrastructure. Taking into account all other relevant aspects of urban planning, monument preservation, building culture, housing management and social aspects, the aim is to show which concrete energy-saving potentials exist and which measures can be taken to reduce CO2 emissions in the short, medium and long term.

In this way, the concept for urban planning is intended to be a planning aid for investment planning in districts that is geared to the overall efficiency of energy-efficient measures. The creation of a neighbourhood concept as part of the energy-efficient urban renovation also enables an active survey of the citizens living in the neighbourhood and the subsequent evaluation of the data collected. Actively reaching out to citizens is an important public relations tool for advancing climate protection in the private sector as well.
