%X The paper examines the effect of the solar chimney¡¯s stack height, depth, width and inlet position on the interior performance (air temperature and speed at 1.20 m height above the ground) as well as proposes an optimal tropical solar chimney design. Simulations show that the output air temperature remains constant while the solar chimney¡¯s width is the most significant factor influencing output air speed. The solar chimney¡¯s inlet position has limited influence on the output air speed although regions near the solar chimney¡¯s inlet show an increase in air speed. Furthermore, a regression model is developed based on the solar chimney¡¯s stack height, depth and width to predict the interior air speed. To optimize solar chimney in the tropics, the recommendation is to first maximize its width as the interior¡¯s width, while allowing its stack height to be the building¡¯s height. Lastly, the solar chimney¡¯s depth is determined from the regression model by allocating the required interior air speed.
