CLIMAGRE

Grenoble-Alpes Métropole (GAM) is embarking on an ambitious journey to implement an innovative solution that integrates technical, economic, and social dimensions. This initiative will model and quantify the positive impact of new urban projects on the region’s resilience to climate change, paving the way for a greener, more sustainable future.

The solution will evaluate the effects of planned redevelopment projects on critical factors such as urban heat island (UHI) mitigation, thermal comfort, and carbon sequestration. By leveraging advanced modeling and data analysis techniques, it will also provide insights into how these changes directly influence the region’s biodiversity—a key pillar of ecological balance.

Beyond its technical scope, this project is designed to captivate and engage local actors and citizens alike. It will serve as a powerful communication tool, raising awareness about the tangible benefits of sustainable urban development. At the same time, it will enhance decision-making processes for key stakeholders at GAM, including elected officials, urban planners, and climate experts, by providing clear, actionable insights.

With this forward-thinking approach, GAM is setting a benchmark for climate-resilient urban transformation while inspiring collective action and building stronger community connections.

The CLIMAGRE solution is a fully interactive 3D Digital Twin of the Grenoble GrandAlpe area—showing its present state and simulating its evolution 5 to 10 years into the future after the GRANDALPE 25 projects. This model, layered with UHI analysis, will illustrate the benefits of proactive green space policies, such as cool roofs, green infrastructure, and water bodies.

Through scenario simulation tools, city planners and stakeholders will be able to test and visualize the impact of urban design decisions on mitigating urban heat islands, making evidence-based strategies accessible and effective.

This initiative aims to drive a sustainable future for Grenoble, where technology and community engagement work hand in hand to address the challenges of global warming.

CLIMAGRE propose a comprehensive, multi-layered approach:

Integrated Data Platform

A robust, horizontal data platform will gather data from a variety of sources—sensors, satellite imagery, open data portals, and citizen applications. This data will be cleaned, standardized, and unified to enable seamless analysis and cross-correlation.

Advanced Data Processing

Using AI and machine learning, the platform’s processing layer will provide actionable insights through predictive analysis across key sectors such as mobility, environment, security, and buildings. This will empower urban planners, policymakers, and stakeholders to make informed, data-driven decisions.

Digital Twin of Grenoble GrandAlpe

CLIMAGRE will create a detailed Digital Twin of the Grenoble GrandAlpe district, showcasing its current state and simulating its future after the completion of eight planned regeneration projects. This Digital Twin will integrate urban heat island (UHI) analysis and will be accessible via desktop, web, and Virtual Reality platforms. It will enable both technical and non-technical stakeholders to explore and interact with this highly visual representation of the district.

Compelling Visual Storytelling

To engage policymakers and the public, we’ll produce a high-quality, five-minute movie summarizing the project. Through stunning visuals, clear infographics, and easy-to-understand language, the movie will highlight the key outcomes of the initiative, including 3D fly-through clips of the Digital Twin layered with UHI analysis.

Data-Driven Insights

The project will integrate data provided by Grenoble-Alpes Métropole—orthophotography, LiDAR, cadastral information, historical records, and satellite imagery—and layer it with geospatial analysis using AI. Outputs will include:

  • Urban Heat Island (UHI) index
  • Land cover maps
  • Tree canopy density
  • Pervious surface maps
  • Land surface temperature maps
  • Water bodies and carbon storage maps

The solution will feature customizable dashboards, interactive heat maps, and detailed 3D visualizations. These tools will allow city planners, researchers, and citizens to explore how urban heat islands evolve and how regeneration efforts mitigate their effects. Vulnerability maps will identify at-risk populations and areas, enabling targeted action to protect those most affected.
