Progress beyond the state of the art, expected results until the end of the project and potential impacts (including the socio-economic impact and the wider societal implications of the project so far)
During the SUPER-i project, investment blueprints were crafted for each pilot to bundle all energy-efficiency (EE) measures into a single financing package. The main core of these blueprints are specifically tailored Public-Private Partnership (PPP) contracts: Shared-Savings, Guaranteed-Savings (with or without public grants and financial-institution backing), Direct-Credit-Line and Energy-Supply contracts which can be replicated also in other contexts and other countries. Through the sister project SUPERSHINE, dedicated crowdfunding platforms will be launched to attract investments from financial institutions with also the support of a one-stop-shop platform which is currently under development and which is going to streamline access to financing, technical support and procurement services.
Potential reduction in electricity and gas bills:
Italy (Montasio & Boito), with average annual electricity and gas bills of about €1,250 per dwelling, 59.3% reduction translates to roughly €737.5 in potential energy savings per dwelling per year.
Slovenia (Nesa 26), under a guaranteed savings PPP, the all-intervention package is expected to deliver €442.7 in potential energy savings per dwelling per year.
Denmark, under a guaranteed savings PPP the all-intervention package is expected to deliver €298.2 in potential energy savings per dwelling per year.
General Findings by Country (SUPER-i pilots)
Following the detailed road maps provided by the SUPER-i project, these are the potential energy savings and Returns on Investment that can be achieved under the recommended PPP contracts.
Italy: Montasio and Boito are expected to achieve a potential 60% of annual energy savings; Housing association expected Return On Investment (ROI) is 12.9% and the Energy Service Company (ESCO’s) expected ROI is 11.34% under the shared savings contract.
Slovenia: Nesa 26 is expected to achieve a potential annual energy savings of 72.6%; The housing association’s expected ROI is 15.5% under the Guaranteed-Savings PPP backed by EKO Sklad loans and rent-fund guarantees.
Denmark: Borlgumparken, Afdeling and the other sites are expected to achieve a potential annual energy saving of 47%-54%; The housing association’s expected ROI is 7.1%-13.5% while the ESCO expected ROI is ranging between 8.9%-13.4% under the Shared and guaranteed saving contracts.
Potential expected Impacts
Socio-Economic: Pilot deep EE retrofits are projected to cut tenant energy bills by up to 75% (e.g. Montasio falls from 40% to 14% of income spent on energy) and reduce the share of thermally uncomfortable homes from 60% to 21% in Italy.
Wider Societal: By actively involving 118 unique housing organisations and 50 financial institutions, SUPER-i has created peer networks that will accelerate replication across Europe, raising renovation rates from the current 1% toward the 3% target. Capacity-building workshops have upskilled over 150 banking and ESCO professionals, embedding new PPP and risk-sharing frameworks into normative practice.
Environmental & Health: SUPER-i proposed EE measures are on track to avoid hundreds of tonnes of CO2 annually (130 tCO2 for Montasio, 50 tCO2 for Boito) and slash operational energy use by over 60% in pilot buildings. These potential savings not only support the EU Green Deal’s climate-neutrality goals but also improve indoor comfort and reduce cold-related health risks among vulnerable residents.
Together, these blueprints and technical, financial, and environmental analyses results demonstrate SUPER-i’s state-of-the-art approach: seamlessly integrating technical modelling, bespoke PPP contracts and local regulatory compliance into replicable, high-impact EE investment packages.
