EU Horizon 2020 lighthouse project (2015–2019): Stockholm retrofitted the 1960s Årsta district with smart energy renovation, consolidated deliveries and mobility solutions, cutting energy use in the demonstration buildings by over 60%.
what does this mean?
The strongest source is the operator's or the city's own reporting — an official report, dataset or press release. It grades who did the looking — not how well the project went. All four grades →📊 Impact
In the Årsta demo site, three refurbished 1960s buildings (36,307 sqm) cut final energy demand by 3,333 MWh/year and CO2 by 1,187 tonnes/year — part of 12 smart solutions demonstrated in Årsta during the 2015–2019 EU Horizon 2020 project.
🎓 Lesson
Deep retrofits pay off, but replication stalls without financing models for ordinary landlords.

The demonstrator ends. What stays?
Four European districts were wired up as time-limited demonstration projects with an agreed finishing date. That is the honest way to run an experiment — and it puts the interesting question at the end rather than the start.
