✎ Corrected 27 Aug 2026 Publication date recorded for 3 sources. What changed →
A stretch of Neusser Straße in Nippes served as RheinEnergie and the City of Cologne's SmartCity test bed: street lighting replaced with LEDs by the end of January 2014, charging points for electric vehicles, smart-home and smart-metering equipment installed in some flats of the Nippes Tower and in a bookshop — fitting the whole street with smart meters remained a plan — and the sensor-based ParkPilot guidance system, which covered around 800 spaces with 27 dynamic LED displays from 2 June 2020, was funded by the federal economics ministry and ended after three and a half years in 2024.
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
LED conversion cut street lighting energy by about 50%, saving roughly 5.4 tonnes of CO2 a year; the commercial buildings converted so far save 541,748 kWh and about 307 tonnes of CO2 annually, an average of 65%. RheinEnergie's final report on ParkPilot puts average search time down by up to 45%, distance driven down by up to 41% and use of the available spaces up by seven per cent, with the project supervisor estimating 550,000 to 700,000 km of parking-search driving avoided each year — about 60 to 70 tonnes of CO2 — when the system is actively used.
🎓 Lesson
Every figure here is the operator's own, and the two most quotable ones are bounded in ways a headline drops: the parking gains are 'up to' values from RheinEnergie's own closing report, and the kilometre saving is explicitly conditional on drivers using the displays. The energy numbers are more interesting for what they leave out — the businesses that converted save about 307 tonnes a year, while the same page puts the potential across all businesses on the street at about 2,216 tonnes. The demonstrator measured the ones who volunteered. And the metering layer that the name implies never left a few flats in one tower and one bookshop.

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.
