本研究以台灣不同地區商業建築立面為應用對象，探討太陽能光伏系統(PV)和微藻培養光生物反應器系統(PBR)之發電潛能和減碳效益。研究過程上，先以SolidWorks模擬小球藻NTU-H15之PBR設計，並且使用元晶太陽能所生產的TS72-BMH-530 H1太陽能板模組其功率高達20.5%，再使用Revit:Insight模擬日射取得，將數據整理為Netlogo程序，分析不同情境下的結果。研究結果顯示，在建築立面上，光生物反應器系統產生之沼氣和太陽能光伏系統具有相近的發電潛力。然而由於藻類的碳封存特性，光生物反應器系統更具減碳之優勢，其減碳效能較太陽能光伏系統高出4到7倍。本研究也發現，由於光生物反應器系統藻類的生長速度並非隨著日射量增加而線性成長，而是在達到臨界強度後趨向一個定值，因此特別適合使用於日射量中等之建築物立面。本研究之成果為建築師、決策者和其他利益相關人提供了更多再生能源選擇，也揭示其與永續建築設計整合發展之可能性。

This research assesses the energy generation and carbon reduction potential of integrating solar photovoltaic cells (PV) and microalgal photobioreactors (PBR) systems on commercial building facades in various regions of Taiwan. By combining data from diverse sources, including literature reviews, SolidWorks simulations for PBR panels, and the use of PV panels TS72-BMH-530 H1 with an efficiency of 20.5%, alongside Netlogo for solar energy simulations, this study provides a comprehensive analysis.
The findings reveal that PBR systems, cultivating Chlorella sp. NTU-H15 on building elevations, achieve electricity production comparable to PV systems. However, PBR systems stand out in carbon reduction due to algae's carbon sequestration capacity, reducing CO2 by approximately 5 to 8 times more than PV systems.
Moreover, PBR systems exhibit a slight electricity production advantage at moderate sunlight intensities, while PV systems perform better in higher or lower intensities, identifying an optimal sunlight range for PBR systems' superior electricity generation.
This research underscores the benefits of implementing PBR systems on building elevations, leveraging lower solar energy received on these surfaces. It provides practical insights for architects, policymakers, and stakeholders to optimize energy efficiency and carbon mitigation in the built environment.
The study contributes to sustainable architectural design and renewable energy integration, advancing green energy adoption and carbon reduction strategies for Taiwan's buildings. Ultimately, this research paves the way for a cleaner and more sustainable architectural landscape.
