Abstract :
In recent decades, urban policy-making has been raised as a significant and scientific topic in major cities of the world, and it has received several attentions from urban studies. One of the topics that is not paid attention to in climate approaches, especially in sustainable architecture, is the consideration of solar energy in buildings, but a lot of attention to solar energy has unfortunately caused that to some extent other renewable energies such as Wind energy and its significant impact on natural ventilation are passively neglected. Paying attention to this case can be taken into consideration by the officials in order to pay attention to the optimization of energy consumption in urban policy making. One of the effective solutions in this field is the use of natural ventilation in residential buildings, determining a suitable direction for creating blinds and receiving wind with positive pressure and benefiting from this influential climatic element in the interior spaces of the building. In this research, an attempt was made to investigate and simulate natural ventilation conditions in residential buildings in Shiraz using Vasari energy simulation software, and parameters such as wind speed, wind direction, wind temperature, and other influencing factors were investigated. and be analyzed. According to the results of the simulation and examination of the twenty-year average of the climatic indicators of Shiraz city, it can be said that if the issues related to natural ventilation and the creation of blinds in the building are considered and the optimal orientation angle can be obtained from solar energy and Also, use wind energy to reduce the load on the building's mechanical facilities throughout the year. that the optimization of energy consumption has been done and in the scale of residential buildings in the metropolis of Shiraz, it can lead to the reduction of fossil fuel consumption to a significant extent.
