Bridging the Gap: A Comprehensive Review of EPC and SRI Calculation Tools in Europe

This study provides an in-depth analysis of the landscape of Energy Performance Certificates (EPC) and Smart Readiness Indicator (SRI) calculation tools within the European Union, addressing critical gaps and deficiencies in current methodologies and systems. Through field research, literature review, and extensive engagement with stakeholders, this research offers a comprehensive assessment of existing tools based on a range of criteria, including data collection practices, backend methodologies, user experience, and interoperability among others. Particular emphasis is placed on the emerging generation of tools developed through the NextGenEPC projects, highlighting innovations and advancements in the field. Key outcomes include the quantification of tool accuracy improvements, user interface enhancements, and increased interoperability metrics. Additionally, a European atlas of EPC and SRI tools is introduced, offering a panoramic view and comparative analysis of the tools available across EU member states. This atlas is envisioned as a pivotal resource for technical partners, market participants, and policymakers, providing critical insights into prevailing practices and fostering the adoption of harmonized, efficient tools for smarter and more sustainable buildings. The study identifies areas for improvement and potential pathways for the development of more efficient, user-friendly, and interoperable tools, thereby contributing to the enhancement of building energy performance and smart readiness assessments across Europe.
