Evaluation of reduction effect on thermal load inside and outside of concrete building with wooden decoration by numerical analysis

The thermal load reduction effect inside and outside a building with steel-reinforced concrete construction coated by heat-treated wooden decoration was estimated by actual measurement and numerical analysis. The model structure for actual measurement was built by using a steel-reinforced concrete cube (sides 3 m). The diurnal range of building body surface temperature and conductive heat flux and the thermal load inside building decreased upon covering the concrete building with wooden decoration. The insulation performance of the panel increased with the thickness of the wood. Thus, the important role played by wooden decoration is related to the thermal insulation of buildings.
