This deliverable reports the work carried out by TIMEPAC concerning the integration of SRI and sustainability indicators in EPCs, with the main focus on determining the dependency of the information requirements between the SRI, the sustainability indicators and the energy performance calculation, an evaluation of the potential extraction of additional energy and flexibility improvement measures based on the SRI and sustainability indicators; and the identification of common data-collection methods to evaluate the response of target audiences (EPC experts, energy auditors, building owners, building managers and ESCOs). Once again, it has been confirmed that the reliability and relevance of the data are of the highest importance when calculating the SRI and selected sustainability indicators.
To promote the use of the SRI and sustainability indicators, the TIMEPAC Code of Conduct for Smart Readiness and Sustainability Rating has been created. It represents a set of guidelines, values and principles that are considered fundamental for the successful, professional and transparent calculation of the SRI and selected sustainability indicators. The Code of Conduct is generated based on experiences gained in six countries participating in TIMEPAC. In an international comparison, the results are reviewed and several common and transnational challenges have been identified. These include the complexity of use, problems with the auditor’s subjectivity and potential problems with the price for the final users. Our experiences confirmed that specific and tailored recommendations for performance improvements must be provided to the final user to make the SRI and the sustainability rating useful. This means that the SRI and the sustainability rating should be combined with energy auditing and energy performance assessments to be cost-effective.
The conducted fieldwork revealed that the competencies of the SRI and the sustainability auditors should encompass a diverse range of technical and soft skills derived from various disciplines. It is clear that a background in mechanical, electrical or civil engineering provides a strong foundation for the SRI and the sustainability auditors. However, a proper combination of technical knowledge, soft skills, and continuous learning is what makes the SRI and the sustainability auditor truly effective in this role.
