Study of Urban Heat Islands (UHI), thermal properties of urban surfaces and development of CityVox software for quantifying and mitigating urban thermal effects.
Lille is the 2nd most UHI-affected city in France (88% of population exposed). In Marseille, UHIs interact with the Mediterranean climate during heatwaves. RESILIENCE quantifies these effects and evaluates mitigation strategies.
Software developed by IUSTI, based on 3D voxel approaches. It imports 3D maps, calculates surface temperatures from radiative energy balances and simulates heat flows at fine resolution.
Intensive measurement campaigns including: albedo and emissivity (IUSTI portable emissometer), surface temperatures (thermal camera), meteorological measurements at twin sites and the Saint-Jérôme campus (Marseille).
Updating urban-scale CO₂ emission inventories to constrain UHI models and support effective climate mitigation decisions.
CityVox validated in both cities
Sub-metric thermal mapping
Updated GHG inventories
