Building-Ecofit: An Extended Framework for Residential Home Retrofitting

The absence of cohesive, technology-aware frameworks for energy-efficient building retrofits leads to inefficiencies, jeopardizing both corporate success and energy and emission reduction targets. Our end-to-end, all-stakeholder framework leverages advanced technologies, such as precise structure and performance modeling techniques, optimization and simulation methods, and digital twins, seamlessly integrated into a unified process supported by sophisticated data management. This holistic approach unleashes the synergistic technological potential throughout the retrofit project, significantly improving the inherent decision-making processes. Additionally, we introduce a conceptual collaborative digital twin ecosystem for the generation of knowledge in retrofitting and building automation systems, and pinpoint areas for further research.
