London's EU smart district planned up to 300 smart-parking places and put sensors in 46 bays. Its energy system, told to cut bills, would have burned more gas, not less.

Part of 1001 Smart Cities — 1,216 documented projects · 🏙️ 15 more in London · 🏘️ Smart districts guide · ⚡ Energy projects

Royal Borough of Greenwich was London's demonstrator in Sharing Cities, an EU Horizon 2020 smart-district project (2016–2021) alongside Milan and Lisbon. Greenwich retrofitted two social-housing estates, adding solar panels on one and an electric heat pump with a back-up gas boiler on the other, built EV charging into street lampposts, and added smart-parking sensors, an e-bike loan scheme and an energy-management system. Programme funding was about €25m.

Completed 📅 2016–2021

📊 Impact

Imperial College London, the programme's own evaluation partner, estimated from building models calibrated on pre-retrofit metering, rather than from measured post-retrofit data, that the heat pump at the Ernest Dence estate would cut heating emissions by 47% while raising running costs by 19%. Its energy-management system met the same trade-off: run to minimise cost, it favoured the gas boiler and its modelled emissions rose rather than fell. The lamppost chargers delivered 22,812 kWh between October 2018 and August 2021, with hourly utilisation under 25%.

🎓 Lesson

Plan and evaluation drifted apart: London's 2015 approval foresaw retrofits of 362 properties and up to 300 smart-parking places; the final appraisal covers two estates of 95 and 172 dwellings and sensors in 46 bays, and models the estates' savings instead of measuring them. A system told to cut bills will burn the cheaper fuel: without storage, the evaluators found, choosing between cost and carbon came down to running the boiler or the heat pump.

The kerbside plug, and the number nobody publishes

Where residents park on the street, charging has to go into the street furniture. All four did that. Only one of them says how often the plugs are actually used — which is the number the whole genre turns on.
