| Abstract |
This paper focuses on applications to a solar energy utilizing(hereafter referred to as suncatcher) system for the improvement of daylight and thermal performance in the north facade of building. This suncatcher system uses the same principle as reflecting solar collectors and is similar to the "Le four solaire d'Odello" of French. This paper performs its fundamental study through the simplified numerical model. Preliminary results indicate the suncatcher system could provide profitable conditions for daylight and solar thermal collection of the north facade in all climates. As a passive device, application of suncatcher baffle outside the north facade in building could significantly increase the level of daylight and thermal collection on a sunny day. Consequently, the suncatcher system is proved to be an effective device for the improvement of daylight and thermal performance in the north facade. An additional study is required to establish the complete suncatcher system on the basis of this research. This approach could have implications for energy efficiency and conservation, effectively utilizing the free resource of solar radiation. |
