Abstract: This study is a part of the research project The aim of this study is the analysis of this interaction building – urban fabric and of the impact of the building mass on the surrounding unban fabric. MEIGEVILLE driven by IRSTV (Research Institute on Cities) in which our laboratories are partners. The Two cities will be studied in this project. The first is Nantes, showed on Figure 1, the second one is La general objective of the project is to take into consideration local climatic data of cities in building thermal behaviour simulation and to set up a coupling between these two kinds of simulation. At Rochelle. As shown on the figure, the studied district of Nantes, called Pin sec, is cut in five zones according to its building types. On the site, we find block of flats as well as dwelling houses. The age of first, climatic data will be processed in order to obtain the input data at a city scale. Our project will focus then on the urban microclimate, to predict overheating periods within the studied location, in two cities. This part will involves a G.I.S. method to convert geographical maps into digital database. In this study, the morphological analysis approach is depicted to clarify different district areas in one city from G.I.S. data. This investigation takes into account the buildings architecture by the calculation of different morphological parameters. In a second part, the methodology for the urban microclimate simulation is exposed, based on the first par results. Finally, the global warming data, obtain from a specific meteorological model is used for the building simulation. The obtain results for different years until the year 2100 highlight a regular increase of assessed building energy consumption and indoor air temperature peaks. At last, the coupling of the urban heat island and global warming effects with the building simulation is outlined.
