摘要

全球能源需求量不斷大幅增長，並促進世界各國替代性能源發展趨勢，因此整合再生能源系統於建築物是一項重要的能源開發與永續經營策略。國內外再生能源業者不斷研發可裝置於建築物各部位之模組化構件，若能將太陽能系統成功整合於既有外遮陽型式，將可開發出更多可使用潔淨能源的應用空間。
百葉外遮陽板目前廣泛應用於建築物，除了能降低夏季室內空調負荷，於寒冷季節可調整葉片角度使陽光進入室內，並能兼顧建築物的美觀。本研究已開發出水平百葉外遮陽板整合太陽能集熱水器系統原型，並於屋外以數位資料擷取系統紀錄大氣環境資料及集熱器效能物理參數，以驗證評估其集熱性能。
研究成果顯示此整合方案可減少二氧化碳排放量及節省傳統能源使用量，具備市場開發潛力，可提供太陽能產業、政府及建築設計者參考。

As the growth of global energy demand continues to surge and drives countries all over the world to develop alternative energy, the development of integrative buildings with renewable energy systems becomes an important policy for energy exploration and sustainable management. The domestic and foreign industries of renewable energy continue to research and develop modular components that can be installed on any part of any buildings. If solar systems can be integrated effectively with the current external shading devices, there would open up more opportunities for the application of clean energy.
Currently, louvre shading devices are widely applied in all kinds of buildings. In the summertime, such devices can reduce the load of indoor air conditioning, whereas during the cooling seasons they can serve to adjust the angles of shading blades so as to control the amount of sunlight entering the buildings. They would also give dual attention to the aesthetic aspects of buildings. This research has developed one model for integrating solar water-heating system with external louvre . To evaluate its performance in terms of heat-collecting efficiency, certain digital data is derived from the recording of outdoor environmental atmospheric data, combined with the solar collector’s physical parameters, and then applied to carry out the performance evaluation of this integrative model.
The research findings also show that this integrative model could reduce the emission amount of carbon dioxide and lower the amount of traditional energy consumption. Based on the conclusion that the model does have strong market potential, the research suggests that the solar energy industries, governments and building designers should consider this model for the future reference of practice and policy-making.
