The document discusses the ENERFUND rating tool, which scores and maps opportunities for deep energy renovations of buildings. It was developed to address gaps between public expectations, trustworthy retrofit opportunities, and available funding. The tool uses energy performance certificate and other building data to provide ratings and identify sound business opportunities for retrofit companies, funding opportunities for institutions, and priorities for policymakers and municipalities. While energy performance data availability varies greatly between countries, the ENERFUND tool demonstrates the potential of open data to promote ambitious energy renovation targets.

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

3. THE CONTEXT

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

5. ENERFUND APP – SCORING & MAPPING TOOL
app.enerfund.eu
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. 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. 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

13. DEMONSTRATION OF AN APP

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. 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. 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
