| Outline of Final Research Achievements |
In winter, direct solar gain system to get solar heat directly to the floor from the windows has been taken as simple and effective technique, but tended not to be able to use all of heat storage capacity because of the obstacles such as the furniture or floor finishing materials. So we proposed the blind dividing near-infrared range to the ceiling and it can improve of indoor thermal environment and energy saving.
Furthermore, it is important the balance of heat gain of solar energy through window, heat storage and insulation for preventing the heat loss for comfort indoor environment. The suggested direct gain system is installing the phase change material in wide surface, and dispersing the solar radiation by blind of window. There will be made comfort thermal environment by heat storage and radiating.
