 Phase change material has a large thermal capacity. This thermal capacity is effective in keeping heat load more flat. I analyzed thermal flow of phase change materials by finite difference method and thermal flow of normal building materials by response factor method. Room temperature fluctuation is calculated combined method. And the theories were compared with experimental values. As a result, the calculated value is well according to experimental value. These theories were incorporated into a heat load calculation program LESCOM developed by the author. The simulation of application of the system to factory has also shown that the system contributed substantiality to increased room temperature. In conclusion, the walls with built-in PCM bag have been found to be effective in heating load reduction.
