Impact des formes urbaines sur le microclimat extérieur des tissus urbains anciens et nouveaux de la ville de Constantine.

Urban reality of our urban fabric is facing serious problems since independence, led mainly by inadequate urban forms, not respecting the climatic conditions of the home base. So, those problems have altered the urban ecosystem and lead to uncomfortable urban spaces. However, the old forms were able to adapt the local climatic conditions and giving more adequate urban solutions. The purpose of this paper is to be aware of the influence of the antique building complexes shape and the new one to create a favourable microclimate for the appropriation of outdoor spaces. For an evaluation approach that involves the use of an experimental method within the competence of ENVI-met3.1 software, the study demonstrated that the old tissues exhibit compact building complexes are more adapted to semi-arid climate of Constantine then those of building complexes exploded.
