  1. 1. ENERFUND: ENergy Retrofit FUNDing rating tool – Lessons learned and future challenges Jure Čižman Jožef Stefan Institute - Energy Efficiency Centre (JSI-EEC) Ljubljana, SLOVENIA
  2. 2. THE CONTEXT Co-funded by the Horizon H2020 Framework Programme of the European Union under grant agreement no 695873 EU EE targets become more ambitious EU Buildings: the largest final energy consumer Source: -32,5% ENErgy Retrofit FUNDing rating tool
  4. 4. THE PROBLEM Deep renovation of buildings suffers from the gap between: • the public’s expectations, lack of awareness and mistrust, • trustworthy and financially sound retrofit opportunities • and the provision of funding investments and incentives DEEP RENOVATION Public awareness and trust Trustworthy retrofit opportunities Funding schemes and incentives
  5. 5. ENERFUND APP – SCORING & MAPPING TOOL Can rate and score deep renovation opportunities Based on EPC data, lists of certified installers, governmental & financing schemes >>> multi-criteria methodology Results shown in an interactive map GIS mapping software Filtering, comparison of buildings, CBA More features are under development!
  6. 6. WHO IS TARGETED? • FUNDING INSTITUTIONS: recognise new investment opportunities, provide targeted loans • RETROFIT COMPANIES or ESCOs: identify sound business opportunities, get instant review of possible energy savings in individual buildings • POLICY MAKERS: design and promote targeted incentives • MUNICIPALITIES & LOCAL COMMUNITIES: prioritise buildings which need to be retrofitted • PUBLIC: enhance awareness & trust regarding EE
  7. 7. MAIN OUTCOMES • ENERFUND tool: open source, fully dynamic user-friendly online GIS application • Analyzed the outcomes of existing initiatives. • Conducted market research for the needs of retrofit companies, financial institutions and municipalities/regional authorities • Promotion of the tool to all relevant stakeholders
  8. 8. ARCHITECTURE Ticketing / Management CI Server Source Control Database Application Server Static Web Server / CDN GIS Server ETL Server MANAGEMENT / HOSTING SOURCE CODE SYSTEM / HOSTING THE APP • Based on mapping capabilities • Everything geocoded • Adaptable & flexible to any data type • Open source • Easy-to-use FROM THIS TO THIS
  9. 9. EPCs INCLUDED CYPRUS In total 7.896.176 EPCs >73 MIO unique building data

  11. 11. MAIN FEATURES • Filtering based on: • Energy rating • Potential energy rating • Ownership status • Windows energy efficiency • Roof energy efficiency • Walls energy efficiency • Main heating fuel • Type/usage of buildings • Floor area • Year of construction • ENERFUND score • Comparing / exporting / printing
  12. 12. ENERFUND SCORE Ownership Occupancy Area Average Prices Own contribution Area Noise Level Potential Energy Saving Open source data ENERFUND Score 10% 100% WEIGHT 5% User Input Total Floor Area Erection year 50% 10% Open source data Open source data Open source data 5% User Input User Input 10% 5% SOURCE
  14. 14. FURTHER POTENTIAL DEVELOPMENT • Drag and click selection / Polygon selection • Address search • .csv custom dataset export (1 GB raw data) • Custom reports based on interests • Inclusion of other types of data, e.g. noise levels, average renovation costs, etc. • Aggregation of data by post code or street • Combination / correlation of EPC data with other data
  15. 15. FINAL CONCLUSIONS ON ENERFUND APP • Proven as versatile tool that could be used for a variety of data or needs, e.g.: • Can identify gaps between policies and needs • Useful for promoting green mortgages and policies for energy poverty (vulnerability energy analysis). • Demonstrated to all groups of and many stakeholders • Features 73+ mio of unique building data • High visibility: 12.300+ unique users since Sep 2017, with a 2 min. average session duration and 10% returning visitors
  16. 16. FINDINGS & RECOMMENDATIONS • Limited availability of open data; huge difference from (EU) country to country; lots of available data not geocoded; missing energy related data (e.g. certified installers…) • Many databases are outdated (e.g. most often on funding schemes and incentives) • Availability of transparent data urgently needed as basis for the definition of climate policy targets • Need for alignment with INSPIRE directive • Geocoded energy data should become compulsory within EU directives and programs • EU Commission to issue Guidelines on Environmental Information / INSPIRE / PSI / GDPR Directives
