在吾人生活環境保持充足的日照是必要的。近來日照權的研究較著重於技術性的 解決方式;無論如何，它是較少著重於法律上的權利分析。事實上，日照權的研究必須結合 環境權、侵權行為及決策優勢的過程。本文不同於「傳統環境權理論」，其首要目標在評析 侵權行為以供環境決策和建築管理分析者之參考。本文展現一個日照權分析的整體架構，亦 明白描述法律位階的可行階層系統以應用於環境影響評估上。本文內容包括環境權分析、侵 權行為取向、日照權涵構及其應用，此結果應可改善超高層建築地區日照條件及其環境品質。 此外，在日照權的認知及未來管制方向亦作一論述。

　　　　　An adequate amount of sunlight must be maintained in our living environment. Recent studies involving sunlight right have emphasized a technological solution. However, the law of right analysis has received only limited attention. In fact, studies involving sunlight right must be matched by environmental right, tort approach and decision-making priority processes. This study differs from the "traditional environmental right theory". This study aims primarily at reviewing and criticizing tort approach for the reference of environmental decision-making and architectural management analysts. This study presents an overall framework of sunlight right analysis. Also briefly described is the feasibility of applying a hierarchical system of law position in environmental impact assessment. The contents of this paper includes environmental right analysis, tort approach, sunlight right context and its application. Results presented herein can hopefully improve the sunlight condition and environmental quality in high-rise building areas. Moreover, recognition of sunlight right and its control direction in the future are discussed as well.
