A Local Digital Twin earns its keep the moment a citizen, a city or a community can act on it. This page follows that route: why it matters, a use case you recognise, and the tool that does the work. Sovereign by design, open by construction.
Three claims on this page can be checked without asking us anything.
The impact views show what changes for citizens, cities and communities, before any architecture.
Mobility, energy, heat, flood, air quality or aviation. Each one is a concrete way in.
Every tool opens with a plain explanation and why it matters.
Working references for the examples on this page.
Use these tabs as your first speaking moment. They turn the Builder into a benefit-led story before anybody sees architecture, standards or implementation detail.
The earlier Experience Builder used a six-step participatory journey. This event version keeps that structure and makes each step easier to understand at a glance.
Select a use case, define the territory, form the team and start from shared context.
Who benefits, what problem matters, and why the project matters in people’s lives.
Break the challenge into activities, decisions, data needs and opportunities for evidence.
Translate citizen and city stories into scenarios, services, data, models and interfaces.
Assemble the shared understanding into a practical, replicable use case.
Activate tools, test a path, gather feedback and improve through a visible learning loop.
These cards are designed as quick audience hooks. Every card jumps to a matching story anchor or tool area so the buttons always do something useful in a live demo.
Neighbourhood energy transition, retrofit choices and visible planning trade-offs.
Trips, emissions and better route choices made easier to understand and compare.
Climate information and neighbourhood interpretation that support safer living conditions.
A straightforward entry point for discussing local risk, scenarios and evidence-based reaction.
Cleaner streets, lower emissions and stronger public legitimacy through visible evidence.
Visual co-design for more climate-neutral and more liveable neighbourhoods.
Resilience-oriented thinking for infrastructure, public space and continuity.
Airport and tourism scenarios linked to CO₂, operations and citizen-facing sustainability.
Every tool in the toolbox becomes a live demo button here, with a plain explanation, “why it matters”, suggested speaking lines and optional working links.
These are intentionally simple. They help you keep the demo focused on lived outcomes rather than platform complexity.
Positive Energy District planning and sustainable living are repeatedly positioned as core examples in the 3DxVERSE and event materials.
Live line: “This helps a neighbourhood see retrofit, energy and rooftop choices more clearly, together.”
Mobility and emissions monitoring are used as a concrete route to making cleaner travel and better decisions easier to discuss.
Live line: “This helps cities make mobility trade-offs visible instead of abstract.”
Airport operations, tourism and CO₂ are framed as a citizen-impact and sustainability story, not only an operational one.
Live line: “This makes airport sustainability feel understandable to more than airport specialists.”
Cartagena leads the EUTwinLink pilot in LDT4SSC, carrying the Positive Energy District work and the question of how one city’s learning travels to another.
Live line: “This is also about how one city’s learning can travel to another city more easily.”
These are included because the source materials explicitly contained them. They give you a clean way to move from the Builder into concrete examples during the event.
