Urban climate modeling with EtiC model

A better understanding of urban climate is needed to adapt cities so they become more resilient to heat waves. This understanding will allow to manage cities in such a way that they do not accentuate the phenomenon of urban heat island. The paper presents a new model called EtiC based on 2-D micro-meteorological models for the rural and urban boundary layer modeling. The EtiC model simulates the thermal behavior of buildings by taking into account the thermal inertia of walls, floors, and roofs, as well as ventilation, heating, and air conditioning. It also considers visible and infrared radiation. The EtiC model was tested on three experimental cases in Basel, Toulouse, and two areas of Paris, for which RMSE values of 1.06, 0.77, 0.8, and 0.84 were obtained, respectively.
