Abstract

The color change at outside wall of home can be influential for heat exchange at house wall, not only at outside wall but also the inside too. For this research we using a house miniature which dimentional are 1x1x1,7 m3 for wide, large and hight. So we can estimate the comfortable of house is comfort for occupy or not. In this research, the color variation is used at the wall start from colorless, white, grey, and yellow. When the outside wall is affected by heat of Sun Light, it can make radiation then heat conduction from the outside wall to the inside, it can make the temperature at home is rising and the humidity is decreasing. There is a force convection from the exhaust fan can make the heat flowing away from the inside of house to the outside and it’s phenomenon keeps the humidity can be stable or constant. From this experiment is gotten that the type of paint color make the highest temperature at outside house wall is grey with 53,85 0C. Then the without paint wall in the second in order with 53,86 0C, the third is yellow with 46,03 0C, and the fourth is white with 44,41 0C. It can be happened because the grey color has the highest absorb if it’s compared to the another color like yellow and white. Consideration result show that dark color’s have internal heat higher than bright color’s, so bright color’s more economical when using energy.
