Abstract

Building retrofitting is vital for meeting European climate targets and transitioning cities 7 to climate-neutral status. Beyond energy efficiency, true sustainability necessitates a holistic ap-8 proach, encompassing environmental, social, and economic dimensions. The RETABIT project is 9 creating a geospatial data-driven platform to compute key performance indicators, assisting urban 10 planners in comprehensive assessments. To enhance decision-making, a large language model-11 based multi-criteria analysis method is proposed, automating processes for city planners and over-12 coming challenges tied to manual assessments
