Abstract
In energy-efficient buildings, natural ventilation using solar chimneys greatly reduces
energy consumption. In this study, a solar chimney was installed in a three-story building to
examine the flow rate of the floors while balancing the flow rate of each floor. To predict the
flow rate, a fluid dynamics model was developed based on a computational fluid dynamics (CFD)
method with a calculated model of RNG k-e, heat flux 600 𝑊/𝑚2 . By changing design
parameters, the air flow was investigated.
