How we estimate the Climate Vulnerability Index (CVI)

MindCity:  Vulnerability map of Barcelona

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.

2. Urban upgrade based on solar shadings

3. Thermal demand models

Simulation of cooling and heating demand based on a Resistor-Capacitor (RC) Model calibrated according to each building’s archetype. The model uses an electrical circuit to simplistically mimic the building’s thermal dynamics.
