This study deals with water evaporative cooling by means of roof spraying. The research is aimed at gaining maximum cooling effect on roof water spraying system. Therefore, compare to the other similar research, this research sets higher water supply rate. The passive cooling effect in buildings and the optimum rate of water supply are examined experimentally through the use of two experimental structures. The paper shows the quantitative relationship between the rate of water supply and cooling effect by setting two different types of water supply rate, one is 30.79kg/m^2・h. and the other is 45.29kg/m^2・h. By analyzing the result of experiment and comparing to the other similar research, relationship between the rate of water supply and cooling effect are clarified. The higher the water supply rate, the more the cooling effects.
