| Outline of Final Research Achievements |
Heating energy accounts for approximately 25% of residential energy consumption in Japan. In this study, we focused on direct solar heat gain into the room through the windows to reduce heating energy consumption. In order to use direct gain effectively, it is essential to balance heat insulation and heat gain and thereby stabilize room temperature by storing heat. Latent heat storage material was used in this study. It was expected to have high room-temperature stabilizing effect by performing phase change in the vicinity of the setting temperature and showing a grasp of heat storage effect. We also proposed NIR film (Near-infrared reflective film) that distributes solar radiation in the near-infrared range upward in order to use the ceiling as the main thermal storage and thus stabilize room temperature. Furthermore, we conducted some studies by actual measurements and numerical calculations from a full-scale test building to test the feasibility of solar-heating by direct gain.
