This report summarises the activities undertaken in TIMEPAC Task 3.3 “Building Renovation Passports from the analysis of enhanced EPC data” of WP3 “Verification Scenarios”. The primary objective of this work package is to confirm the outputs of the Transversal Deployment Scenarios, which were developed in WP2, with local stakeholders involved in building certification processes.
With this purpose, TIMEPAC partners organised workshops with representatives from Austria, Croatia, Cyprus, Italy, Slovenia, and Spain to gather their feedback. Through these workshops, valuable insights were gathered, aiding in identifying training requirements necessary for participants to actively contribute to advancing current certification practices. These efforts align with TIMEPAC‘s goal to adapt to the latest Energy Performance of Buildings Directive revisions.
The findings indicate a pressing need for a broader utilization of Building Information Modeling (BIM) in building renovation endeavours. However, significant challenges emerged, notably the absence of a centralized BIM model database and the imperative for designated institutions to oversee data accuracy within these databases. Economic justifications for generating Energy Performance Certificates (EPC) and building Renovation Passports (RP) for low-energy-consumption buildings were also scrutinized.
Attention was drawn to the necessity of implementing enhanced automatic checks for data entry to enhance EPC data quality, considering factors such as occupants’ influence and other variables impacting data accuracy. Furthermore, the lack of standardized regulations across countries was underscored, prompting recommendations for streamlining EPC procedures and incorporating advancements in technology and climate considerations alongside intensified training for EPC issuers.
Insights regarding the exploitation of EPC for local, regional, and national energy planning underscored the critical role of enriched EPC data for long-term scenario calculation tools. Suggestions included expanding EPC coverage to non-residential buildings and incorporating additional indicators such as post-scenario CO2 emissions and investment assessments. There is a clear demand for comprehensive planning tools that integrate data and strategic planning across various governance levels.
Workshop insights concerning evaluating and verifying energy-saving opportunities based on EPC highlighted the importance of calculating savings in BRPs based on actual building usage. Recognizing the challenges of expecting one individual to cover all aspects of the BRP, there is a call for a national training programme to bolster expertise in this area.
In conclusion, the workshops stressed the significance of utilizing real operational data for accurate evaluations of energy-saving opportunities and the need for robust training programs and the development of user-friendly tools to support energy planning activities. Key issues identified from the workshops include the necessity for national-level reforms, improved automatic checks, standardized regulations, and enhanced EPC data utilization. Comprehensive training programmes are deemed essential to address these challenges effectively.
