Effects of demographic change for the use of natural resources – scenarios and approaches to action

The project examines resource related implications of demographic change and changing user preferences for the action field of housing and construction. A particular focus is put on older single family home neighborhoods. Use of resources is analyzed in terms of land use, material flows and energy consumption.

The project is structured into two major work-packages. With the first work-package we calculated a model based large scale (nation-wide, federal states) estimate of resource effects of demographic changes and possible shifts between different sectors of the housing market (e. g. between detached houses and multiple dwellings). General leverage points and options for action were identified.

With the second work-package we analyzed development scenarios, resource-effects and approaches to action for specific case study communities in close co-operation with local practitioners. Two case study communities were selected, one with a decreasing and a second one with a stable population. In addition, in order to capture broader experience beyond the two intensive case studies, further interviews were conducted with experts from 12 additional cities facing different development contexts and challenges.

A comprehensive report of the project results is under preparation as a volume of the UBA TEXTE publication series (In German language with an English summary). Intermediate results can be found here:
