Exteriors made of steel sheets for architectural applications have many superior features compared with ceramics, for example, lightness, good formability and so on, however, have large heat conductivity. As a result, in the summer daytime, the solar radiant heat transfers into the interior of structures easily, then, it occurs high interior temperatures, and the energy required for cooling increases. Therefore, pre-painted steel sheets which can restrain the solar radiant heat, reduce or omit heat insulators and conserve the energy for cooling, moreover, which can be also colored without restraint, were required. In this report, guidelines for pre-painted steel sheets with reflectiveness of the solar radiation were given for conserving energy, especially, by evaluating the effects of coatings and substrates.
