Urban Heat Island modeling

In the beginning of 2021, we completed the development of a tool for simulating surface temperatures in an urban environment, using a weak coupling approach between temperatures and air velocities

The approach allows for comfort indexes computations at each point in space. It integrates the coupling of fluid mechanics simulations, together with sunlight and thermal dynamic regimes for the built environment.

Results of a case study around the Strasbourg train station (France) are presented next.

The following animation shows the evolution of comfort levels over the first week of the year Sit back and relax!
