现在人们普遍认为，日光照明评估的标准方法-日光系数-应该被基于全年使用标准化气候文件得出的太阳和天空条件预测的发光量绝对值的度量标准所取代。向更现实的采光测量的转变在发光量的模拟和将模拟数据减少到易于理解的度量方面引入了显著水平的额外复杂性。模拟组件，至少对于具有标准玻璃材料的建筑物来说，是相当好理解的。然而，在指标的构成上没有达成共识，其制定是一个正在进行的积极研究领域。此外，非住宅建筑和住宅建筑呈现出非常不同的评估场景，目前尚不清楚是否有一个单一的指标适用于两者。本研究以一户住宅为背景，探讨住宅采光指标之适用性。除了提供日光照明的任务，并披露减少电力照明使用的潜力，我们还调查了非视觉效果，如夹带的昼夜节律系统的指标的制定。
It is now widely accepted that the standard method for daylighting evaluation - the daylight factor – is due for replacement with metrics founded on absolute values for luminous quantities predicted over the course of a full year using sun and sky conditions derived from standardised climate files. The move to more realistic measures of daylighting introduces significant levels of additional complexity in both the simulation of the luminous quantities and the reduction of the simulation data to readily intelligible metrics. The simulation component, at least for buildings with standard glazing materials, is reasonably well understood. There is no consensus however on the composition of the metrics, and their formulation is an ongoing area of active research. Additionally, non-domestic and residential buildings present very different evaluation scenarios and it is not yet clear if a single metric would be applicable to both. This study uses a domestic dwelling as the setting to investigate and explore the applicability of daylighting metrics for residential buildings. In addition to daylighting provision for task and disclosing the potential for reducing electric lighting usage, we also investigate the formulation of metrics for non-visual effects such as entrainment of the circadian system.
