Etude du rôle de la végétation dans la création de microclimats urbains : approche combinée de mesures et de modélisations à différentes échelles

Abstract : The urban heat island phenomenon causes thermal discomfort to residents. lmproving the microclimate in urban areas is therefore one of the concerns of urban plan ners. The greening of cities (with lawns, trees, green roofs, etc.) is a promising solution, as the transpiration of plants and the shadows of trees have a significant impact on the thermal balance of the surrounding atmosphere. This act must be planned to optimize the benefits of vegetation. A key challenge today is thus the development of a microclimatic simulation model capable of reproducing the climatic conditions of a street, or even a vegetated urban neighborhood, with the aim of proposinga decision support tool for the development of sustainable cities. The aim of this thesis is to study how to consider vegetation and especially trees, in a 30 microclimatic model to simulate the microclimate of a neighborhood. Two models, LASER/F and RATP were applied at the scale of a tree and an urban park to carry out this study.
