A former industrial peninsula turned positive-energy district: the Hikari block (2015) produces as much renewable energy as it consumes, anchoring the 2011-2017 Franco-Japanese Lyon Smart Community pilot -- a smart-grid data platform, solar EV car-sharing and home energy monitors. The EU-backed Smarter Together programme (2016-2021) then added district heating and more solar capacity across the quarter.
what does this mean?
The strongest source behind this entry is an independent peer-reviewed or academic study. It grades who did the looking — not how well the project went. All four grades →📊 Impact
A peer-reviewed evaluation of the Smarter Together lighthouse programme reports that the Lyon site's refurbishment of around 35,000 m2 of floor area achieved a total energy saving of around 1350 MWh/a and an annual CO2 reduction of about 643 t-CO2/a, alongside around 449 kWp of new PV generating about 497 MWh a year. The paper reports Lyon separately from Munich and Vienna; the often-quoted 37.6 kWh/m2a saving is the three-city aggregate, not Lyon's.
🎓 Lesson
The number that travels is the wrong one. Smarter Together reports 37.6 kWh per square metre and year, and that is the three-city figure for Lyon, Munich and Vienna together; Lyon's own line in the same paper is about 35,000 square metres refurbished, 449 kWp of new photovoltaics, 1350 MWh a year saved and 643 tonnes of CO2 avoided. Aggregates from multi-city programmes are the commonest way a district's performance gets overstated, and the only defence is to read the section where the cities are reported apart.

Forensic record — source dossiers, gaps, hashes and the exact revision this page renders
This layer records what is known about each source, what is still missing, and the exact snapshot this page is rendering. A missing date, archive or hash stays visible as missing.
Awaiting operator and domain-expert review; publication of this revision implies neither.

Known limits of this passport
- Publisher names and source languages have not yet been classified; domains are recorded without guessing.
- Existing source notes are descriptive locators, not page- or paragraph-exact citations.
- A missing archive, publication date or content hash is shown as null rather than inferred.
- The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
