During the architectural design process, it is particularly important to emphasize the aspect of the heat flow in buildings. Therefore, by raising the question of the heat flow in buildings, we perform an in-depth examination of the following parameters: climate conditions, material characteristics, and thermal conduction. For the most part, the research will focus on examining the thermal conductivity, and materiality applied in buildings throughout the design process. In other words, this study will demonstrate several key points: (a) analyze the proposed methodology, and challenges within the architectural design process based on the climate context; (b) associate each of the stages with diverse parameters; (c) represent three separate structures situated in different climate zones and, (d) finally, the driving factors affecting the architectural design development process. The research is primarily driven by the idea of bringing together two aspects: the sustainable treatment of the buildings and environmental awareness in architecture. Finally, this study merges two approaches within the design development process: technical and environmental. Therefore, the main focus of this study is placed on the technical and technological aspects of the detail in architecture. Based on these two approaches, three architectural design proposals are demonstrated.
