High resilient cities in practice
This solution helps municipalities and organizations go digital and manage their data effectively on a local level.
It is a key tool for smart cities, energy planning, adapting to climate change, and making decisions about urban retrofitting
What does it do? It checks out KPIs for buildings and helps planning for energy transition and climate change adaptation:
City microclimate model (100x100m)
Rates how buildings are vulnerable to climate issues
Forecasts energy retrofitting and adaptation strategies
Sends heat wave communications—4 days ahead
Supports designing urban green spaces and shelters
Description
Geo-AI powered models
We develop machine learning and Graph Convolutional Neural Network (GCNN) models
To enable learning patterns from geo-structured data (buildings, streets, use, energy, etc).
Extrapolation of KPIs for all buildings when no real data is available
It is a digital landscape, a dynamic knowledge graph that brings urban exploration to life.

Climate Vulnerability in Barcelona at building level
The Climate Vulnerability Map of Barcelona is a geospatial analysis tool designed to identify the buildings most at risk during extreme heat events.
It evaluates key performance indicators (KPIs) for buildings and supports climate change planning
It provides an assessment of all residential buildings in Barcelona(61,000)
What is it?
CVI
How we estimate the Climate Vulnerability Index (CVI)
Vulnerability index to asses heat wave resilience
Climate vulnerability is typically framed within three key dimensions defined in the IPCC's Third Assessment Report (Intergovernmental Panel on Climate Change) in 2001:
Exposure
Sensitivity
Adaptive capacity
Although most studies classify indicators using these three categories, our index introduces additional levels to provide a more nuanced analysis while remaining aligned with the traditional framework.
Climate variability and extreme events
Energy indicators
Building characteristics
Indicators groups (KPIs)
Vulnerability map
Infrastructure indicators
Assess the availability of essential public services (schools, climate shelters, social housing) and the strength of social networks to understand community support capacity.
Health indicators
Analyze the relationship between climate and health outcomes to identify vulnerable populations and prepare healthcare systems.
Demographic indicators
Not all groups are equally vulnerable. Analyzing factors such as gender, age, income, migration status, and unemployment allows for the development of more detailed CVIs.
Socioeconomic indicators
Understand urban resilience through factors such as housing costs, energy poverty, household debt, and gaps in social protection, which worsen during economic crises.
Vulnerability map
Indicators groups (KPIs)
Climate vulnerability Index (CVI)
Data preprocessing – Select input data to calculate the indicators.
Framework selection – Determine which indicators positively or negatively affect the CVI.
Granularity definition – Select the spatial scale.
Normalization & weighting – Harmonize indicators and assign weights.
Aggregation – Combine indicators into groups to obtain a final value.
⚠️ Challenge: Each study adapts its CVI to its specific context and priorities.
CVI Construction
Vulnerability map
Our approach:
Building the CVI
Vulnerability map
Use of empirical cumulative distribution function to assign a value to each building for a given KPI:
🎯 Outcome: A practical tool for both policymakers and citizens to explore climate vulnerability and support decision-making.
