摘要

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，如何使太陽能的利用不再只是建築物設計完成之後的附加設備，而是在設計初期或修繕工程時便能納入整體考量，並且太陽能熱水器產業發展至今，已經形成了各種類型的較完整的產品體系，為我國建築中太陽能應用的普及與奠定了基礎。
本研究目的經由建築物西向立面開口部，設置垂直式外遮陽與百葉式外遮陽整合太陽能集熱系統之裝置，並參照CNS國家標準之相關規定，以足尺模型與戶外實測之方法研究其性能。研究成果顯示如下：

1.垂直式外遮陽整合太陽能集熱系統中，集熱器效率係數FR(τα)與集熱效率η的實測分析可知，集熱板90度面向正南方時優於集熱板0度面向正西方與集熱板45度面向西南方。
2.百葉式外遮陽整合太陽能集熱系統中，集熱器效率係數FR(τα)與集熱效率η的實測分析可知，集熱板0度面向正西方時優於集熱板45度仰角。

Integration of renewable energy systems in buildings is an important energy development and sustainable strategy, in order to make solar energy efficiently for using, it is not just an additional equipment of a construction any more, but an early design procedure or designs within the facilitate repair work period to help to incorporated into the overall planning. The present development of solar water heater industry has formed various types of complete product systems, and formed a strong fundamental base in solar energy applications in our country.
Purpose of this study is that through the building facade openings to the west, set vertical and louver-style exterior shading devices, to integrated solar collector system. Furthermore, with references of National Standard of CNS, the methods of full-size model and outdoor measurements were conducted in this study. The result is as follows：
1.In Vertical external shading integration with solar collector systems, the measured analysis of Collector efficiency factor FR (τα) and collector efficiency η, Collector plate 90 degrees for the south is better than the collector plate 0 degrees for the west, and collector plate 45 degrees for the southwest.
2.Louver-style shading integrated with solar collector system, the measured analysis of Collector efficiency factor FR (τα), and collector efficiency η, Collector plate 0 degrees for the the West is better than the collector plate 45 degrees elevation.
