Upscaling urban residential retrofit for the EU's low carbon future: Challenges and opportunities

With respect to the EU climate and energy goals, a major challenge for cities lies within retrofitting the existing urban building stock. Accordingly, many EU funded projects have a focus on (residential) building retrofit and experiment with new techniques and operational procedures, financing schemes, end user engagement strategies and governance process setups. These have led to a wealth of experiences and replicable successes that deserve to be maximally disseminated. The present policy paper summarises main learnings and formulates recommendations stemming from the analysis of retrofit demonstration projects in the scope of the Smart Cities Information System (SCIS), as well as from a broader set of related information sources.
