Abstract

Daylight spectral simulation is crucial for designing functional, healthy spaces and predicting light interactions. It is essential for accurate non-image-forming effects of light calculations. This study addresses the knowledge gap in reproducing indoor daylight spectral conditions in the built environment. Using varying levels of geometry (LOG) and information (LOI), simulation accuracy was assessed by comparing it with experimental data from two offices over three days with cloudy and clear sky conditions. The lowest accuracy was found with high LOI and low LOG simulations. For the highest accuracy, specific material spectral properties are needed, while spectrally-neutral materials at low LOG produced comparable results. Simulations near and facing windows were the most accurate. The study concludes that to reproduce indoor daylight spectral conditions, modelling should use either the lowest or highest geometry and information complexity, depending on available modelling time and required accuracy.

模型复杂性对室内日光光谱模拟影响的实验研究
日光光谱模拟对于设计功能性健康空间和预测光相互作用至关重要。它对于准确计算光的非成像效应至关重要。本研究填补了在建筑环境中再现室内日光光谱条件的知识空白。利用不同的几何(LOG)和信息(LOI)水平,通过与两间办公室三天内阴天和晴天条件下的实验数据进行比较,评估了模拟的准确性。发现高 LOI 和低 LOG 模拟的准确度最低。要达到最高精度,需要特定的材料光谱特性,而低 LOG 的光谱中性材料则能产生类似的结果。靠近窗户和面向窗户的模拟结果最为准确。研究得出结论,要再现室内日光光谱条件,建模时应根据可用建模时间和所需精度,使用最低或最高的几何和信息复杂度。
