The article outlines how inconsistent energy‑efficiency data across Europe limits renovation progress and describes current efforts to improve comparability and support coordinated policies.
Europe faces persistent obstacles in advancing energy‑efficiency improvements due to fragmented data, divergent indicators and uneven methodologies across Member States. This lack of alignment complicates comparisons, affects households and authorities, and weakens the design of evidence‑based renovation policies under the Energy Performance of Buildings Directive (EPBD).
The article highlights ongoing work to address these issues, including the Integrated Energy Performance of Buildings Assessments (IEPB) project’s efforts to harmonise methodologies and develop a shared data model. Improved data quality and comparability are seen as essential for coherent renovation strategies, better monitoring and coordinated action, particularly in addressing energy poverty.
The text underscores the need for consistent metrics, stronger digital infrastructure and closer cooperation to support effective renovation policies and reduce energy demand across Europe.
