The purpose of this study is design to develop double-walled design of natural materials (bamboo) to reduce radiant heat into the building. Reduce construction costs by using natural materials that are readily available locally. And can reduce the cost of energy use in the residential conditions occurring prior to cozy up to. The results of the double-walled design forms the third and then put to the test transmission of the sun. And select the appropriate model to test the temperature of the material other five by the results of the experiment showed that during the day as the first the second the fourth the fifth the temperature inside the box. The outside temperature is lower than the highest temperature. Especially in the case of five minimum temperature inside the box than any event since the space between two walls of floor to localized heat. But in this study tested the two-story wall material that attaches to the outside of the building is important. Wall mounted double-walled bamboo in the open with temperatures under all circumstances.
