Proven Smart City Upgrades for Energy, Transport and Buildings — Ready to Copy

energyPilotedTRL 7

Imagine taking three entire city districts — in San Sebastian, Florence, and Bristol — and upgrading them like you'd renovate an old house: better insulation, smarter heating, electric buses and bikes, and a digital brain that ties it all together. That's exactly what REPLICATE did across real neighbourhoods with real residents. They retrofitted hundreds of homes, rolled out electric vehicles and bike-sharing, connected buildings to district heating, and built an ICT platform to manage it all. Then they packaged the lessons so three more cities (Essen, Nilufer, Lausanne) could copy the playbook.

The business problem

What needed solving

Cities across Europe face the same challenge: aging buildings waste energy, transport systems rely on fossil fuels, and city services operate in disconnected silos. Retrofitting at scale is expensive and risky when every district is different. Municipal leaders need proven, replicable solutions — not one-off experiments — that combine energy efficiency, clean transport, and smart infrastructure into a package they can actually deploy.

The solution

What was built

The project delivered real-world smart city upgrades across three cities: 240 retrofitted homes (20,400 m2) and a 13-block district heating network for 700 flats on the energy side; 32 e-bikes, 2 on-demand EV minibuses, 6 electric car-club vehicles, and EV charging infrastructure on the transport side; plus an integrated ICT platform with smart grids and intelligent lighting. A total of 41 deliverables document the full deployment and replication methodology.

Business applications

Who can put this to work

Real Estate & Property Management
enterprise
Target: Property developers or housing associations managing large residential portfolios

If you are a housing association dealing with aging building stock and rising energy costs — this project retrofitted 240 residential homes (20,400 m2) in Bristol and a 13-block district with 700 flats in San Sebastian, proving cost-effective retrofitting techniques at neighbourhood scale. The replication playbook they built means you can adapt their methods without starting from scratch.

Urban Transport & Mobility Services
any
Target: Municipal transport operators or mobility-as-a-service providers

If you are a transport operator struggling to electrify your fleet and fill last-mile gaps — this project deployed 2 on-demand EV minibuses, 32 e-bikes in a corporate scheme, expanded a car club with 6 electric vehicles, and installed EV charging infrastructure across three cities. Their big data mobility platform shows how to integrate these services into one system.

District Energy & Utilities
enterprise
Target: Energy utilities or district heating operators

If you are a utility company looking to modernise heating networks — this project connected a 13-block district heating network serving 700 flats to a gas CHP energy centre, hybridising local biomass, recovered heat, and natural gas. They also deployed smart grids on the electricity distribution network, giving you a tested model for integrating renewables and demand-side management.

Frequently asked

Quick answers

What would it cost to replicate these smart city solutions in my district?

The project data does not include specific per-unit costs for the retrofitting or mobility deployments. However, as an Innovation Action with 44 partners across 6 countries, the solutions were designed for cost-effective replication — the entire point was to create scalable models that follower cities (Essen, Nilufer, Lausanne) could adopt.

Can these solutions scale beyond a single neighbourhood?

Yes — the project was explicitly designed for replication and scaling. After piloting in San Sebastian, Florence, and Bristol, replication plans were generated for Essen, Nilufer, and Lausanne. The ICT architecture was built to be interoperable and scalable from the start.

Who owns the IP and can I license the technology?

The consortium includes 44 partners with 27 industry players and 12 SMEs. IP is likely distributed across partners. Contact the coordinator (Ayuntamiento de Donostia San Sebastian) or specific technology providers in the consortium for licensing terms.

What regulations do these solutions comply with?

The project addressed EU Smart Cities and Communities requirements under the SCC-01-2015 topic. Solutions were deployed in real urban environments across Spain, Italy, and the UK, meaning they had to meet local building codes, transport regulations, and energy standards in each country.

How long did deployment take and what's a realistic timeline for my city?

The full project ran from February 2016 to January 2021 — five years covering planning, deployment, and monitoring across three cities. Based on available project data, the district heating deliverable was delayed from month 24 to month 36 due to reworking, which gives a realistic picture of actual urban deployment timelines.

How does the ICT platform integrate with existing city systems?

The project deployed an ICT architecture spanning from Internet of Things sensors to applications, designed to integrate solutions across energy, transport, and buildings. Smart grids connect consumers, producers, aggregators, and the municipality. Intelligent lighting uses PLC (power line communication) for IP service integration.

Is there ongoing support or just a final report?

The project is closed (ended January 2021), but the replication methodology and 41 deliverables document the full deployment process. The project website (replicate-project.eu) and the 6 follower/lighthouse city network provide a community of practice for new adopters.

Consortium

Who built it

With 44 partners across 6 countries, this is one of the larger Smart City consortia in Horizon 2020. The 61% industry ratio (27 industry partners) and 12 SMEs signal strong commercial involvement — these are not just researchers writing papers. The coordinator is the City of San Sebastian (a public authority), which means the project was driven by real municipal needs, not academic curiosity. Having cities as both customers and leaders means the solutions had to actually work for residents and city operations. The mix of 6 universities and 2 research organisations provided technical depth, while the 9 other organisations (likely NGOs, associations, and city agencies) ensured citizen engagement.
