This thesis focuses on giving concrete answers to the problems related to the slow integration of climate issues into local town planning documents. In particular, the analysis focuses on the particularly vulnerable context of southern France, taking into account the specificities that link it with the Mediterranean basin. As a matter of fact, the mere uncontextualized technical response does not favour the speeding up of this transformation process. As well as the numerous guides already created, which are seldom combined with the awareness raising efforts of public and private actors and thus remain an end in themselves. In addition, the possible negative effects of climate change, in particular overheating which is especially dangerous for the most vulnerable groups of people, require a degree of priority for action. For this reason, special consideration is given to the heat wave issue as well as to urban heat islands (UHI). Therefore, a technical response will be proposed through local urban planning documents, in particular the local urban planning plan “PLU” to improve summer comfort and provide a short and medium term response to the adaptation of cities. Through the possible maneuvers of action offered by this local town planning document (encouragement, obligation and prohibition) recommendations have been developed. The purpose of these recommendations is to provide a rapid response to improve climatic conditions both on the building scale and on the urban scale. Through bioclimatic principles, the inclusion of greenery, the inclusion of refreshing elements, and the prohibition of the use of some low albedo materials, specific standard regulations are proposed.
