Abstract

When solar radiation passes through a window, its spectral composition changes due to the presence of shades and glazing. While many studies have analysed the impact of different types of glass on correlated colour temperature (CCT), there are only a few cases in which the effect of shading and daylighting systems on this parameter was tested. This work analyses the impact of woven shade fabrics on the spectrum and intensity of daylight conditions in indoor spaces. A combined analysis of horizontal illuminance (Eh) and CCT was performed. It focused on the impact that physical properties of woven shade fabrics – colour and openness factor (OF) – had on the CCT and Eh values. In this study, 11 fabrics with different colours (white, grey and black) and varying OF were analysed. For the set of studied woven shade fabrics, it was found that fabric OF and colour had a significant effect on CCT and Eh. Results show that white and grey fabrics provided spaces with lower values of CCT than black fabrics. CCT values were compared with those proposed by standard EN 12464-1:2011.

编织遮阳织物对日光照明相关色温和照度的影响

当太阳辐射穿过窗户时，其光谱组成会因遮阳和玻璃的存在而发生变化。虽然许多研究分析了不同类型玻璃对相关色温（CCT）的影响，但只有少数研究测试了遮阳和日光照明系统对该参数的影响。这项研究分析了编织遮阳织物对室内日光条件的光谱和强度的影响。对水平照度 (Eh) 和 CCT 进行了综合分析。重点分析了编织遮阳织物的物理特性--颜色和开放因子（OF）--对 CCT 和 Eh 值的影响。这项研究分析了 11 种不同颜色（白色、灰色和黑色）和不同开放系数的织物。研究发现，对于所研究的这组机织遮阳织物，织物的开放度和颜色对 CCT 和 Eh 有显著影响。结果显示，白色和灰色织物提供的空间 CCT 值低于黑色织物。CCT 值与 EN 12464-1:2011 标准提出的值进行了比较。
