Natural ventilation is among those effective methods that is useful in hot dry climates. One of its important uses is in the atrium spaces in the office buildings. Although, as a passive solution, it has a significant impact on the reduction of energy consumption, the control of inlet and outflow of air as well as the control of air current temperature has always been a challenge for architects and engineers. This study aims at designing a model to reduce energy consumption and increase airflow inside the atrium. In so doing, the present study reviews the existing solutions in the inactive area. In this way, using computer simulations, the designed model in the energy software is analyzed and compared. The Design Builder Software is used to analyze the natural ventilation inside the building. The results clearly show that the use of a suitable form in the atrium ceilings with the aim of increasing the absorption of direct sunlight can have a direct effect on natural ventilation and thus reduce energy consumption in hot dry areas.
