Light, especially daylight, plays a critical role in human health as the main timer for circadian rhythms. Indoor environments usually lack the correct exposure to daylight and are highly dependent on electric lighting, disrupting the circadian rhythm and compromising the health of occupants. The methodology proposed assesses the combination of natural and electric lighting on circadian rhythms for operational environments. The case study chosen examines a 24/7 laboratory area representing an open-plan shift-work area. Several electric lighting scenarios under different sky conditions have been assessed, considering a variable window size and resulting in a spectrum which establishes the indoor circadian regulation performance according to the amount of light perceived. A set of configurations is presented to determine optimal electric lighting configuration based on natural light conditions in order to ensure a suitable circadian stimulus and the electric lighting flux threshold for different scenarios, benefiting occupants' health while also ensuring energy conservation.
光是人体健康的关键因素，尤其是作为昼夜节律主要计时者的日光。室内环境通常缺乏正确的日光照射，高度依赖电力照明，这扰乱了昼夜节律，损害了居住者的健康。所提出的方法评估了自然光和电力照明对作息环境昼夜节律的综合影响。所选的案例研究检查了一个 24/7 实验室区域，代表了一个开放式轮班工作区域。评估了不同天空条件下的几种电力照明方案，考虑了可变的窗户尺寸，并产生了一个根据感知到的光量来确定室内昼夜节律调节性能的光谱。提出了一组配置，以根据自然光条件确定最佳电力照明配置，以确保适当的昼夜节律刺激和不同场景下的电力照明通量阈值，从而有益于居住者的健康，同时也确保节能。
