Wood Thermal Conductivity Database Construction for the Application of Building Energy Simulation

The increasing interest in the environment and climate change around the globe, while the importance of building energy saving is increasing. The building energy simulation program is used for evaluating of energy performance of buildings. However, an input value of wood thermal conductivity in the programs is different from each other. Therefore, in this study, wood thermal conductivity was measured according to species. Through construction da-tabase by species of wood, the error of simulation program are able be decreased. In addition, if used as a structural and interior of buildings, the thermal conductivity and moisture of the wood is difficult to apply to the program because they were changed according to the occu-pant’s lifestyle. In this paper, thermal conductivity and moisture content.of wood confirmed changes in the constant temperature and relative humidity (25°C, 50% R.H.) condition.
