When solar radiation passes through a window, its spectral composition changesdue to the presence of shades and glazing. While many studies have analysed theimpact of different types of glass on correlated colour temperature (CCT), there areonly a few cases in which the effect of shading and daylighting systems on thisparameter was tested. This work analyses the impact of woven shade fabrics on thespectrum and intensity of daylight conditions in indoor spaces. A combinedanalysis of horizontal illuminance (Eh) and CCT was performed. It focused on theimpact 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 wovenshade fabrics, it was found that fabric OF and colour had a significant effect on CCTand Eh. Results show that white and grey fabrics provided spaces with lower valuesof CCT than black fabrics. CCT values were compared with those proposed bystandard EN 12464-1:2011.
