Digital Twin for urban heat
Urban heat islands, heat stress, exposed populations: a heat wave does not affect an area uniformly, and temperatures can vary from one street to the next. Local governments must now factor urban overheating into their climate adaptation policies, as required by French local, regional and national climate plans, and justify their choices.
The digital twin for urban heat maps surface and air temperatures across your area and cross-references thermal indicators with population and urban vulnerability data. It then simulates your greening, de-sealing and urban design scenarios to assess their benefits before you invest.
STAKEHOLDERS
A shared view for climate, planning and public health teams
Tackling urban heat involves many departments: urban planning, public health, social services, green space management and technical services, as well as elected officials. The digital twin for urban heat brings them together around a shared view, so they can coordinate actions suited to each local context.
Local governments and inter-municipal authorities
Factoring overheating into your adaptation policies means backing every priority with evidence. The digital twin provides the indicators and warming projections to support your decisions, from neighborhood to regional scale.
Technical and urban planning departments
Greening, de-sealing, cool islands: you manage costly projects in constrained public spaces. Localized thermal indicators help you prioritize the most affected areas.
Developers, property owners and social housing providers
Your projects affect the local microclimate. Before-and-after indicators let you quantify their real impact and back up your commitments to the community.
Public health and social services
Heat affects some population groups and facilities more than others. By combining heat stress, at-risk populations and social vulnerability, you can target prevention measures where they matter most.
context
Map, anticipate and manage urban heat across your area
Bring your policies into compliance
Local governments must now address urban heat islands in their local climate plans and regional planning schemes, in line with the national adaptation plan and the national warming trajectory. This complex task affects infrastructure resilience, how human activities adapt and the preservation of natural heritage.
Understand how your area reacts to heat
How does your area actually behave during a heat wave? Without fine-grained mapping, it is hard to pinpoint the neighborhoods, facilities and populations most exposed to heat.
Build a consistent heat strategy
A consistent thermal comfort strategy requires analyzing a wide range of indicators: urban morphology, heat island intensity, heat stress, green spaces and water management. This essential groundwork is often hard to turn into a concrete action plan.
Measure the impact of your projects
How do you objectively measure a development project’s impact on the local microclimate? You need to model the project, compare before-and-after indicators and share a clear, compelling analysis with stakeholders.
OUR PROMISE
Map, anticipate and manage urban heat across your area
Pinpoint urban heat islands street by street, identify vulnerable neighborhoods and populations, and test your cooling scenarios in a digital twin that accurately reflects your area.

In short
A digital twin to act where heat hits hardest
Each indicator is linked to a 3D view of the area, from the neighborhood to the region. You can show where overheating is concentrated, who it affects, and how a development project actually changes the local microclimate. This information can inform a Climate Action Plan (PCAET), support the direction of a Local Urban Development Plan (PLU) or an Integrated Local Urban Development Plan (PLUi), and integrate thermal comfort into a measurable path toward climate resilience.
