Many municipalities have set ambitious aims in order to reduce the emission of greenhouse gases and have developed concepts for climate protection – despite other duties and though cash-flow budgets. Municipalities are therefore important actors on the topic of climate protection. The key role of local authorities for sustainability and climate protection has already be noted in the Agenda 21 and the Earth Summit in Rio 1992: They are on the ground of the problems, are able to develop individual solutions and can integrate climate protection in the city planning.

The research project SANDY ‘From the concept of climate protection towards target group orientated campaigns for retrofits: Strategy, solution concepts and models for dynamic municipalities’ works out solutions for municipalities in order to support their effort for climate protection. It focuses on energetic retrofit of residential buildings. These buildings emit about one fourth of the greenhouse gases in Germany.

To assure the practical use of the results, the project cooperates with different partner municipalities. Especially the demographic situation and dynamic inside the municipalities with their effect on the retrofitting behavior is an important aspect. Increasing as well as decreasing regions have specific challenges and need individual solutions. The same goes for regions with high increasing rates of elderly people or municipalities with a high percentage of people with migration background.

Up to now these aspects and their synergetic effect, for example barrier-free living or health protection, are not considered enough. This leads to unused technical potential. The project does not only analyze the problem but furthermore aims towards the development of solution strategies and providing a tool box to the municipalities. Eventually the results are upscaled to national level using a residential-building-household-model in order to give recommendations for the usage of the instruments at federal level.
