Abstract In this study, in order to examine the method of suppressing the temperature rise of the switchboard exposed to direct sunlight, the variation of temperature in its inside was measured by shading of sunlight. In addition, the temperature changes according to the color of the green and white roof, and the paint color of the switchboard were examined by an experimental method as a Cool Roof effect. The installation of shading net reduced the temperature by about 10℃ or more. The temperature change of colors was measured at 63°C for green and 38°C for white, with a temperature deviation of 25°C. In addition, the gray switchboard surface was 51.4℃ and the white switchboard surface was 43. 6℃, confirming the temperature reduction effect of about 8℃.
