The building façade becomes an integral part of the concept for adaptation of the building to the climate conditions; it should be able to respond and adapt its properties and components with the immediate environment.In the hot and dry climate in Algeria, the contemporary building design, materials, and techniques applied do not properly address the local climate conditions and the final energy consumption. Contrary to this, in traditional building practice, the local materials and passive strategies are used, which responded to the environmental context.This study is focused on improvement of the cooling energy consumption of the contemporary buildings in Biskra City, Algeria. The traditional climatic façade solutions are investigated in order to adapt them to the contemporary buildings. To define and optimize the solutions, dynamic simulation with Vi-Suite add-on Blender 3D software was used. The results show a significant reduction in the cooling energy consumption, which confirms the use of the traditional techniques that can considerably improve the building efficiency.

In order to improve thermal comfort conditions of tertiary buildings through the facades of buildings, a research has been undertaken with the intention of developing a contextually appropriate and energetically efficient facade under the conditions of a hot and arid climate. The study has taken as its starting point the analysis of comfort conditions of a set of office buildings located in Biskra. These buildings were distinguished from standpoints of the treatment of their facades and the materials used. The study proposes to evaluate the thermal functioning of the different materials of the facade, then to optimize their behavior by acting on their material characteristics and the walls composition. The facade, indeed, represents a place of interaction and exchange between the inside and the outside, the performance of which is due to factors that are formal, material and technical. This article presents the main results of the analytical work. The investigation is based on an empirical approach (measurements in situ on real cases) as well as on a parametric simulation study. The results show that the facade represents with excellence the place of interaction and exchange between the interior and the exterior, the performance of which is due to factors that are both material and conceptual. Through a set of recommendations, this study tries to develop a material composition of high-performing facade that can respond optimally to the requirements of a tertiary building in a desert climate, while ensuring a pleasant thermal ambience and low consumption energy.
