由於全球暖化效應，許多研究開始圍繞著如何透過節能減碳來尋求永續發展。而在土木工程中，綠建築即是重要的一環。在建築物建造完成後，綠建築在其使用年限內，透過永續設計，對於能源的節約及再利用，便是最貼近使用者也最直觀的方式。
本研究提出透過Mamdani模糊推論自動控制系統，即時推算出百葉窗葉片的最佳的角度，使陽光所給予建築物內部的最有效的利用，達到智慧節能的目的。透過氣象觀測的歷史資料判斷依據，可以初步建立出模糊推論需要的輸入值及輸出值以及推導出模糊推論的規則。進一步利用Matlab的Fuzzy Logic Toolbox來做大量且即時的運算便可以用電腦自動控制的方式來使百葉窗葉片的角度可以自動隨著陽光的照射做變化。並透過室內溫度及光源分布來進行節能分析以此驗證此模式對於節省能源之成效。

This study presents the automatic control system by fuzzy inference Mamdani, instantly calculate the optimum angle of split blind blades, so sunlight give the most efficient use of the building interior, to achieve the purpose of saving wisdom. Through judgments based on historical data of meteorological observations, we can initially establish the input value and output value of fuzzy inference rules needed and fuzzy inference deduced. Further use of Matlab Fuzzy Logic Toolbox to do large and immediate operation can be automatically controlled by a computer to make way split blind blade angle automatically changes do with sunlight. Through the indoor temperature and light distribution to permit this mode for energy conservation analysis of the effectiveness of energy saving.
