How is it possible to increase homeowners' insulation activity? Answering this question is key to successful policies regarding energy-efficient buildings worldwide. In Germany, doubling today's insulation rate of about 1% is an important element for reaching the government's target of an 80% reduction in energy demand in the building sector by 2050.
This thesis uses an agent-based model analysis to improve the understanding of homeowners' insulation activity and to explore new approaches aiming at its increase in Germany. Two agent-based models were developed and utilized. The first model was developed mainly based on insights derived from a structured literature review. The second emerged from the previous one, incorporating the results of an online survey conducted among 275 homeowners.
The results indicate that homeowners' economic means have little influence on their decision to install insulation. Instead, their insulation decision-making is mostly affected by situational factors and their attitudes towards insulation. Situational factors, such as the condition of the building, are important because they initiate homeowners' individual decision-making processes on insulation. The simulation results show that improving homeowners’ attitudes about insulation by providing information has a comparatively low potential for increasing their insulation activity. Out of the policy options this thesis explored, the introduction of an obligation to insulate the walls within one year after change of house ownership was found to have the greatest impact on homeowners' insulation activity.
Die MENA-Region steht nicht nur vor erheblichen gesellschaftlichen Herausforderungen, sondern weist ebenfalls deutlichen Entwicklungsbedarf im Stromsystem auf und erfordert dessen nachhaltige Transformation. Durch einen möglichst hohen regionalen Verbleib der damit anfallenden Wertschöpfung könnten sich Chancen für Technologieausrüster ergeben. Allerdings herrscht im derzeitigen Marktstadium noch immer hohe Unsicherheit inwieweit zukünftig tatsächlich eine Marktentwicklung stattfindet. Vor diesem Hintergrund erfolgt die Entwicklung eines multikriteriellen Bewertungsrahmens für Investitionen in die lokale Produktion, wobei Aspekte der Transition-Forschung Anwendung finden.
