In the past 30 years, tubular daylight guide systems (TDGSs) have become one of the most popular ways to transport outdoor natural light into the inner space in building design. However, tubular daylight guide systems are not widely used because of the lack of methods to evaluate methods on the suitability of the TDGSs. This study therefore summarizes the daylight performance metrics of TDGSs and presents the estimation methods in terms of field measurements, simulation and empirical formulae. This study focuses on the daylight performance and potential energy savings of TDGSs. Moreover, this study will be helpful for building designers to build healthy, comfortable and energy-saving indoor environment.

在过去的30年中，管状日光导引系统（TDGS）已成为在建筑设计中将室外自然光传输到内部空间的最受欢迎的方法之一。但是，由于缺乏评估TDGS的适用性的方法，管状日光引导系统并未得到广泛使用。因此，本研究总结了TDGS的日光性能指标，并提出了基于野外测量，模拟和经验公式的估算方法。这项研究的重点是TDGS的日光性能和潜在的节能效果。此外，这项研究将有助于建筑设计师营造健康，舒适和节能的室内环境。
