Four kinds of actual-size exterior walls with exterior vented air-layer were installed in a hot box with solar simulator. Although solar reflectance of the outside surface and surface emissivity of the vented air-layer of the four walls were different, the other specifications were identical. Under the given room and exterior temperatures and solar radiation conditions, wall surface temperatures as well as wall inside temperatures and heat flow were measured, changing openings of the vented air-layer set close or open. Based on the measurements, thermal performance of the four walls was compared. Comparison was also made between the measurements and calculations by the method proposed in the previous paper. The result shows that the values obtained by the calculation well represent those by the measurement.
