Natural ventilation is one of the important elements for creating a suitable healthy environment. It provides thermal comfort in buildings. However, the rising building densities and the high prices of land led to an increase in residential densities. Hence, high buildings appeared which obstruct natural ventilation and natural lighting and hinder the air movement around and inside the buildings there for, the need arises for studying problems stemming from opening in facades and the air movement outside and inside the buildings in order to reach natural ventilation for people's comfortable inside the building. The present research discusses the idea of developing styles of architectural designees and exploiting modern techniques in design in order to increase effectiveness of natural ventilation through designing opening in facades in light of the phenomenon of climate change. In this research, the residential building was analyzed, ventilation was studied. Measurements were made. The research followed the analytical method for architectural elements to employ them, Such as the internal courtyards, The wind-catcher, places of openings and their measurements as well the building direction to achieve man's thermal comfort inside the building.
