都市地區集中全球超過半數人口，每年消耗超過70%的能源，隨著人口不斷增加，都市對能源的需求逐漸上升。由於建築部門為都市能源消耗的主要來源之一，其減碳策略對實現全球氣候目標極其重要；然而，受限於技術層面發展困境，暫時無法以建材管理的方式大幅減少建築部門的碳排放量，因此有許多國家達成共識，將節能技術和再生能源利用技術作為永續建築的最終量化指標，以減少城市能源消耗或增加再生能源的使用。
除地面型太陽光電的建置外，也應對屋頂型太陽光電予以考量，因為建成區都市化程度高，適當提高都市的能源自給率，有助於紓解地面型光電的建置壓力。近年有關城市能源的研究大多集中在城市太陽能潛力或城市能源消耗的獨立研究，或是以單一建築進行能源自主的考量。有越來越多的研究表明，都市型態會透過緊湊程度、幾何特徵等因素對建築能耗與太陽光電潛力產生影響。文獻指出建築覆蓋率、街道型態、綠地覆蓋率和建築群朝向等不同的都市型態因素會改變區域內的微氣候條件、太陽輻射量、城市熱島效應；進而影響建築內部能源使用和外部可接收的輻射量，增加光電發電量可能也會導致能源消耗的增加，因此需要釐清減少建築能源消耗及增加太陽光電潛力的權衡關係。
本研究結合能源消耗與光電潛力面向，嘗試探討不同都市型態下減少能源使用與提升太陽能發電量的權衡。本文除前言外分為四個部分，首先回顧相關文獻，探討都市型態如何影響能源消耗與光電潛力；再據以進行研究設計，包含都市型態因子計算、能源績效分析與迴歸分析。本文以臺北市做為實證研究範圍，探討建成區內不同都市型態因素與光電替代率的關係，並透過相關分析，進一步比較都市型態指標對能源績效的影響；最後研究結果發現，以整體而言，都市型態指標對於建築能耗和光電潛力的相關性皆為同向關係，表示減少能源消耗和提升光電使用具有權衡關係；透過迴歸分析可以看到，空間單元內的建築平均高度對光電替代率的影響最大；由於分群對應到能源績效指標的關係相異，應進一步針對不同類型的都市型態對應至不同的建築部門減排策略，以促進城市朝淨零路徑發展。

This study integrates aspects of energy consumption and photovoltaic potential, aiming to explore the trade-offs between reducing energy use and enhancing solar power generation in various urban typologies. The paper is structured into four main sections, excluding the introduction. First, a literature review is conducted to investigate how urban typology affects energy consumption and photovoltaic potential. Based on this review, the research design is developed, encompassing the calculation of urban typology factors, energy performance analysis, and regression analysis. The empirical scope of this study is the Taipei metropolitan area, where the relationship between various urban typology factors and the photovoltaic substitution rate is examined. Through correlation analysis, the influence of urban typology indicators on energy performance is further compared.
The findings reveal that, overall, urban typology indicators are positively correlated with both building energy consumption and photovoltaic potential, indicating a trade-off relationship between reducing energy consumption and increasing photovoltaic use. Regression analysis demonstrates that the average building height within spatial units has the most significant impact on the photovoltaic substitution rate. Due to the varying relationships between clusters and energy performance indicators, different urban typologies should correspond to distinct emission reduction strategies in the building sector to promote the development of cities towards a net-zero pathway.
