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 (E-h) 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 E-h 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 E-h. 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.
