Environmentally and socially compatible construction and housing

What would it mean for housing supply to implement no-net-land take targets from the German Sustainability Strategy of 2016? And how can forms of housing be realised with minimal land take and in an affordable way?

The project, which is funded by the Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection (BMUV) via the German Environment Agency (Umweltbundesamt) draws on the results of the project Trends and tendencies in housing development. The aim of the project is to critically analyse current settlement and land development and to develop scenarios on how no-net-land take targets and the provision of affordable living space can be considered together. The project comprises three work packages:

Existing approaches to assumptions and forecasts of settlement area development and housing demand are analysed. On this basis, an approach for deriving housing requirements based on demographic data is developed by IOER. It allows for a Germany-wide analysis and gives us the possibility to calculate scenarios for future housing demand in 2030 and 2050, which we combine with trends and political objectives for no-net-land take targets.

Small-scale potential for internal development are calculated for four case study regions of regional planning authorities and compared with future housing demand. Here we develop small scale approaches on building level. This makes it possible to analyse the tension between housing demand and a circular land use economy. Knowledge of suitable forms of housing is important here. Accordingly, good examples of sustainable forms of housing are brought together at the neighbourhood/ensemble/building levels. In stakeholder dialogues in the four regions, possible futures are discussed on this basis and the need for further research into environmentally and socially compatible construction and housing is created.

The Leibniz Institute of Ecological Urban and Regional Development is jointly funded by the federal government and the federal states.
