As the current renovation rate in Germany is insufficient to meet climate targets, understanding homeowners’ barriers is crucial. The research revolves around two primary questions: first, identifying the key challenges for self-occupying and rental owners in the context of energy retrofitting, and second, exploring how a start-up can innovatively and profitably tackle these challenges. Key findings reveal significant knowledge gaps and financial concerns among homeowners. In response, “rehome” is introduced, a software startup providing digital renovation guidance and tools.engBusiness planKey problemsGermanySelf-occupying ownersEnergetic renovationmaster thesis203867114
