Designing What Matters: Digital Twins and the Relational Planning of Livable Cities

By utilizing digital twins, real-time data, and artificial intelligence (AI), cities can simulate and prepare for change, ultimately co-creating more livable and equitable futures. We explore how the narrative-rich modeling approach of Barcelona and the policy-driven foresight of Singapore provide distinct yet complementary lessons for emerging urban innovations in Latin America.

With its striking precision and compelling storytelling, Aretian’s latest Barcelona Metropolitan Digital Twin iteration goes beyond mere technical accomplishment. Urban planning is reimagined as a space for experimentation, where data sparks conversation and prediction fosters community engagement.

Singapore’s long-standing use of digital twins showcases a distinct strength, namely its institutional continuity and strategic orchestration.

These models collectively reveal a path forward for Latin American cities, where livability is a continuous, collaborative process rather than a fixed endpoint.

What is a Digital Twin?
Models of physical urban systems, known as digital twins, are dynamic and driven by data, accurately reflecting their complexity. They go beyond being mere static replicas, instead functioning as interactive platforms that simulate change, forecast its impacts, and inform collaborative decision-making processes.

A digital twin in urban planning can digitally replicate an entire city or a specific infrastructure network, combining real-time data from sensors, geographic information systems (GIS), and AI. By combining these elements, we can continuously monitor, develop predictive models, and engage in participatory scenario testing.

AI amplifies the power of digital twins by processing vast data streams, forecasting outcomes, and learning from evolving patterns. By rehearsing interventions beforehand, planners and communities can optimize energy use, improve mobility, and assess the impact of new developments on walkability, heat islands, and overall livability. Digital twins offer a collaborative platform for reimagining governance, where data is transformed into a dialogue and cities are shaped by co-authored futures.

Strategy Simulation for Livability
Digital twins go beyond merely reflecting the current state; they chart potential futures. They function like layered transparencies, enabling us to overlay forecasted developments, assess the outcomes of interventions, and map the ripple effects of policies across time and geography. Simulation, in this context, serves as a strategic care approach, enabling us to foresee and address potential inequities, practice resilience, and design urban spaces that prioritize collective well-being.

By grounding themselves in shared metrics and civic imagination, cities can leverage data and AI to transition from reactive governance to relational planning, ultimately shaping livability in a meaningful way, rather than just measuring it.

Digital twins serve as strategic instruments for achieving territorial equity, allowing us to model various ‘what-if’ scenarios that encompass housing, mobility, and economic development. Consider the balance between the benefits and drawbacks of different interventions, as well as how they might work together.

Barcelona’s Metropolitan Digital Twin as a Civic Innovation Platform
Aretian’s recent presentation at the Telefónica Tower unveiled a groundbreaking Digital Twin for the Barcelona Metropolitan Region, an advanced urban simulation platform designed to model and optimize development at the parcel level. This initiative offers a strategic vision for livability, innovation, and economic regeneration, grounded in data-driven diagnostics and AI-powered foresight.

The Barcelona Metropolitan Digital Twin integrates real-time data visualization, geospatial analysis, and predictive simulations to inform policy and planning decisions. Developed by Aretian and embedded within NVIDIA’s Omniverse platform, supported by Lenovo’s high-performance server infrastructure, the model enables robust “what-if” scenario testing and continuous urban monitoring.

This dynamic framework addresses five major challenges: residential allocation and housing strategy, urban design optimization, mobility and public safety, economic strategy and territorial competitiveness.

By simulating the ripple effects of interventions across time and territory, the Digital Twin supports real-time policy impact assessments in areas such as sustainable development, environmental monitoring, and risk management, positioning Barcelona as a global reference in relational urban planning.

Singapore’s Digital Twin: Governance as Infrastructure
If Barcelona’s digital twin dazzles with narrative precision, Singapore’s urban modeling impresses with institutional choreography. For over a decade, Singapore has treated simulation not as a standalone tool, but as a core component of its governance ecosystem, integrated into long-term planning, regulatory frameworks, and inter-agency coordination.

Through initiatives like the Urban Redevelopment Authority and Smart Nation, Singapore exemplifies how data and AI can support anticipatory governance, where decisions are rehearsed across time horizons and policy domains.

Singapore’s digital twin initiative, one of the first to model an entire nation, translates raw GIS, LiDAR, and imagery data into a comprehensive virtual replica of the country. This model includes reality meshes, building typologies, and transportation networks, enabling more informed planning, management, and decision-making.

What sets Singapore apart is not just the technology, but the strategic framework underpinning it. Legal instruments, implementation protocols, and a robust Building Information Modeling (BIM) strategy ensure that digital twins are embedded across the urban lifecycle, from planning and design to construction, maintenance, and sustainability.

This integrated approach supports efficient urban design and planning, coordinated construction and infrastructure delivery, cost and resource optimization, facility management and lifecycle maintenance, smart city development and environmental stewardship, evidence-based decision-making, and regulatory compliance and institutional alignment.

Singapore’s model reminds us that digital twins are not only technical tools, but they are also civic infrastructures for long-term resilience.

Latin America’s Civic Scaffolds: Digital Twins and the Ethics of Urban Foresight
Complexity, creativity, and constraint are nothing new to Latin American cities. Often, what is missing is not creative thinking, but rather the infrastructure to plan, spaces to test ideas, and collaborative environments to design a better future, which can be hindered by fragmented institutions and unequal access to resources.

With careful adaptation, digital twins can evolve into more than just technical tools. Communities can utilize these frameworks as civic scaffolds to visualize trade-offs, develop inclusive policies, and establish long-term planning rooted in shared values.

In informal, unequal, and fragmented institutional settings, these models provide an opportunity to explore futures that prioritize not only efficiency, but also justice and collaborative creation. The challenge goes beyond technology, involving cultural, ethical, and relational aspects as well. The opportunity lies in shaping digital twins that reflect not only what can be measured, but also what truly matters.

Seeds of Innovation: Santiago and the Livability Equity Map
In Chile, the seeds of digital twin technology are quietly taking root, through smart infrastructure modeling, academic research, and evolving urban data platforms. Santiago offers fertile ground. Although a full-scale digital twin has yet to be developed, its digital foundation reflects the principles of the Livability Equity Map, which serves as a dynamic and layered platform where data, dialogue, and design intersect.

Just as the Map invites cities to rehearse more just futures, Santiago’s early steps in urban simulation reflect a growing commitment to equity-driven innovation, if nurtured with transparency and care.

The Livability Equity Map outlines interconnected pillars that can guide the ethical adaptation of digital twins in Latin America:

  • Territorial Equity: modeling spatial justice across communes and neighborhoods.
  • Inclusive Governance: ensuring privacy, interoperability, and ethical use through clear protocols.
  • Mobility & Accessibility: simulating inclusive transport networks and walkable environments.
  • Housing & Public Space: visualizing the impact of design on dignity, safety, and belonging.
  • Climate Resilience: anticipating environmental risks and enabling proactive adaptation.
  • Innovation & Collaboration: fostering partnerships between government, academia, and civil society.

These pillars provide a strategic perspective to reimagine digital twins as locally rooted instruments of civic care, rather than imported solutions. To build trust, digital twins must be co-created with communities, grounded in ethical frameworks, and stewarded through inclusive governance.

Toward Co-Created Futures
As we navigate the promises and perils of digital transformation, the question is no longer whether cities will use data and AI, but how, and for whom. Digital twins can be more than predictive engines; they can become rituals of co-creation, aligning metrics with meaning, and foresight with care.

For Latin America, the opportunity lies in shaping these tools to reflect its plural realities, where livability is not imported, but cultivated through dialogue, imagination, and trust. In this unfolding cartography of futures, equity is not an add-on; it is the lens through which we design.

Digital twins, data, and AI are not just technical frontiers; they are invitations to rehearse more just, livable cities. As our region meets complexity with courage and creativity, we have a chance to shape these technologies with intention. Let’s co-create digital ecosystems that reflect our values, honor our communities, and expand our collective capacity to imagine.

Livable Urbs is an open space for shared reflection and strategic dialogue. I’d love to hear your thoughts, questions, or experiences.
