The use of natural ventilation and natural lighting through the building envelope is preferred in all buildings. On the other hand, natural air and daylight are taken into the spaces with the vertical voids created in the green building. However, it is a risk for fire safety design that vertical interior voids and ventilation openings in the spaces adjacent to the voids create uninterrupted vertical and horizontal areas. These voids can cause the spread of smoke and flames in a fire event. To prevent the spread of smoke and flames through vertical interior voids in a fire event, in this study a performance-based design was developed for smoke and flame evacuation through vertical interior voids. Pyrosim simulation program was used to monitor smoke level, temperature change, and indoor air velocity. Pyrosim is a program that uses computational fluid dynamics, allows simulation, and includes FDS (Fire Dynamics Simulator) software. Temperature, smoke, and flame level analyses were made with scenarios created by changing the width and height of the vertical interior void in the prototype building, which was designed using the physical model studies in the literature. It was determined that the evacuation speed of smoke and flames increased, and the temperature and smoke level in the rooms decreased because of reducing the width of the inner void and increasing the height of the void.
