Belgrade (Serbia)
The SUPERSHINE Serbian fellow district is a 13-floor tower block in central Belgrade, comprising 72 small apartments (~20 m² each) originally built in the 1960s for single tenants, workers, and retired state employees. The surrounding neighbourhood features typical socialist-era infrastructure, including healthcare, educational, and recreational facilities.
SUPERSHINE supported Belgrade in exploring energy-efficient upgrades, improved living conditions, and resident engagement, adapting renovation strategies to the constraints of older, high-density housing while fostering inclusive and socially sustainable solutions.
Financial Graphs
This figure shows that the Serbian case also performs best when all renovation measures are implemented together under the guaranteed savings model. The full package delivers a return on investment of 11.44% for social housing and 9.62% for the ESCO, both above the 6.11% benchmark. Among individual measures, wall renovation again gives the strongest result, at 8.99% for social housing and 9.47% for the ESCO. Roof and floor measures provide moderate returns, while window upgrades are the weakest option, generating only 2.60% for social housing and 4.23% for the ESCO. Overall, the figure shows that the financial case is clearly strongest when the renovation measures are combined into a single package.
Energy Poverty Graphs
This figure demonstrates a clear reduction in energy poverty after renovation in the Serbian case. Before renovation, households spend 23.90% of income on energy, while after renovation this falls to 15.77%. This reduction shows that energy efficiency measures can ease household financial stress and improve affordability. The chart also indicates that renovation has a meaningful role to play in reducing vulnerability among households facing relatively high energy costs.
This chart shows a strong fall in energy consumption after renovation. Energy use drops from 1,114.08 kWh/sqm before renovation to 728.39 kWh/sqm after renovation. Although post-renovation consumption remains substantial, the reduction still represents a major improvement in building performance. The figure suggests that renovation can significantly lower energy demand in older or inefficient buildings, supporting both cost savings and environmental gains.
This chart shows that renovation improves thermal comfort for a significant share of households in Serbia. Before the renovation works, 22.90% of residents are unable to keep their homes comfortable across hot and cold seasons. After renovation, this falls to 13.17%. The figure highlights the social value of renovation, showing that energy upgrades can improve everyday living conditions while also tackling energy poverty more broadly.
Lighthouses
