In a series of workshops hosted by the Energy Institute Hrvoje Požar, the TIMEPAC project discusses the evolution of energy certification and EPC presentation in Croatia. The events, held on the 8th and 15th of November 2023, brought together key stakeholders from diverse sectors to engage in discussions, identify imperfections, and propose improvements in the Croatian context.
Experts from energy agencies, energy service companies, public authorities, companies, energy certifiers, and building managers participated in the workshops. The collaborative effort provided a rich exchange of insights and opinions, fostering a deeper understanding of the energy certification process in the country.
Bridging Gaps with BIM and New Indicators
Stakeholders underscored the potential of Building Information Modeling (BIM) in data collection and validation, recognizing its value. However, challenges remain, including sporadic use in Croatia and concerns over implementation costs. The introduction of new indicators, such as the Smart Readiness Indicator (SRI), was welcomed as an enhancement to energy building performance presentation. The importance of clear definitions and procedures (in terms of skills, datasets, and software) and the manifestation of new indicators was highlighted by all participants.
Operational Data, Occupant Influence, and Digitalization
Particular attention was given to the need for actual operational data on savings, acknowledging the increasing influence of occupants and users in the energy certification process. Stakeholders highlighted the importance of digitalization, advocating for accessibility to the energy model of the building for professionals and energy auditors. The interoperability of datasets emerged as a crucial aspect requiring dedicated efforts.
Highlight Cost-Effectiveness and Client Benefits
For the Renovation Wave to happen there need to be clear benefits for building users. The energy certification process could become more cost-effective for clients by leveraging previous information and building on existing datasets. Clear definitions and procedures for new indicators were identified as vital components for successful implementation.
The information gathered in TIMEPAC Verification Scenario workshops seek to lay the foundations of positive change in Croatia’s energy certification landscape. These collaborative efforts will pave the way for a more efficient, transparent, and accessible process. The project remains dedicated to empowering building experts and ensuring a sustainable future through advancements in energy certification.
