en messages 1 Retabit is a data-centric platform that facilitates the integration of building renovation into broader urban regeneration strategies by combining energy, economic, and social indicators within a unified system. Drawing from public data sources, it supports municipalities with actionable insights that link renovation projects to wider climate and urban transformation agendas.

en messages 1 Multidimensional indicators Multidimensional indicators
en messages 1 A systematic review of academic and grey literature identified relevant local and regional studies, with eight detailed case studies (e.g. Barcelona, Los Angeles) selected for comparison. Indicators from these cases were cross-checked against the Sustainable Development Goals (SDGs) to ensure relevance, multi-target alignment, connection to Sustainable Energy and Climate Action Plans (SECAPs), applicability to residential renovation, and availability of open, fine-scale data.
