Abstract In most buildings, solar heat is conducted through radiation and air convection to buildings’ roofs, outer walls and floors. Furthermore, most heat coming into the buildings is by air convection, radiation through window and material’s conduction through the gap of building’s outer walls and windows. These circumstances rise the indoor temperature and increase the power consumption of air conditioners. Considering the power consumption of air conditioners and environmental consciousness, the study compares the proposed improved timber structure wall designed in the study. In the experiment, these two groups of timbers are heated by the same sources under the same conditions for continuous 7.5 hours. While the outer wall temperature reaches 53.1℃, the indoor temperature of traditional timber is 32.6℃and that of the improved timber wall is 24.3℃. The difference shows the proposed timber wall has netter insulation ability than the traditional one, thus reducing the usage of air conditioners.The heat insulation of the improved timber wall proposed by the study raises the heat insulation efficiency and reaches the purpose of carbon reduction and energy conservation.
