The decarbonisation of Europe’s building stock is progressing faster than it was a few years ago. Still, the gap with climate objectives persists, revealing significant imbalances across sectors and technologies.

Neighbourhood‑scale action can reinforce energy security, affordability and social cohesion by integrating renovation, renewable energy and shared infrastructure, offering a practical pathway for local implementation of EU objectives.

This document aims to provide a clear overview of the various Air Infiltration and Ventilation Centre (AIVC) projects and their associated deliverables.

The results from this edition show that the building sector has recently entered a phase of greater improvement, which has reduced the decarbonisation gap. However, these recent improvements remain insufficient to completely close the gap with the climate neutrality trajectory.
