Facing global challenges of climate change as well as augmenting energy prices, energy efficiency and decrease of the emission of greenhouse gases are central political aims of the Federal government of Germany. In total, housing accounts for 40% of all energy use in Germany. Of 39 million dwellings (in 19 million buildings), 75% were constructed before 1979 and show an inadequate energetic quality. In order to foster on-going renewal processes and to support owners of large housing estates by the compilation of integrated concepts, the Federal Ministry of Transport, Building and Urban Affairs invited to a competition "Energetic renewal in large housing estates based on integrated concepts for urban districts" in January 2009. The online-publication shows how this German-wide competition gave new impulses to the housing industry.
