Abstract
Bioclimatic design is a design process that takes into account climate and environmental conditions when designing for optimum thermal comfort with minimum outside energy use. The present study intends to highlight the role of the bioclimatic analysis in design operations at both urban and architectural scale in Guelma city, Algeria. As our challenge is to provide a precise analysis of the climatic conditions, we have resorted to several methods and bioclimatic tools using climatic data from the decade from 2008 to 2017. Each tool consists of presenting and following the intersection of one or more climatic parameters with respect to time. As a result, we have located the bioclimatic floor to which Guelma city belongs, the overheating, the under heating and the comfortable zones have been determined. The findings are significant to draw up the main recommendations and requirements for a bioclimatic design for Guelma city in particular and for regions with semi-arid climate in general.
