Cities are important economic drivers, and also in urban development and rehabilitation and is the guiding responsible for a large proportion of ecological impacts and principle of recent developments regarding urban planning emissions. Physical transformation in urban environments mainly legislation. occurs in form of renewal, rehabilitation and upgrading. Germany’s Federal government offers a number of subsidy programmes, In the national urban planning legislation, the German Building with many of them targeting inner city neighbourhoods, the Code (BauGB) is the most important regulatory document. It improvement of existing structures, renovation of existing defines legally binding land use management, and regulates area- buildings and blocks, as well as the enhancement of green related requirements for urban development and construction infrastructure and public spaces. projects. Another instrument outlined in BauGB are so called Integrated Urban Development Concepts (ISEKs), utilised by Many large and medium sized cities in Germany experience a shift municipalities for the creation of concrete, long-term strategies in growing or shrinking population numbers.
