“…For the diffuse transmittance, an equivalent value of the direct transmittance for an average incidence angle of about 60°has been recommended for use in design calculations [6]. Hemispherical normal reflectance and transmittance properties of a variety of coated and uncoated plastics (teflon, tedlar, acrylic) and fiberglass composites (e.g., greenhouse coverings) are available as a function of wavelength, polarization and incident angle [7].…”

. (2017) Effect of sky conditions on light transmission through a suspended particle device switchable glazing. Solar Energy Materials and Solar Cells, Volume 160, February 2017, Pages 134-140. doi:10.1016/ j.solmat.2016 ABSTRACTA suspended particle device (SPD) switchable glazing changes its state from opaque to transparent in the presence of a power supply. SPD glazing's near normal transmission varies with incident angle and clearness index. Due to a lower diffuse component, higher glazing transmission ensues at higher clearness indices. Transmittance values for different azimuthal incident angle for a SPD glazing for its "transparent" and "opaque" states have been determined. In Dublin, below 0.5 clearness index, isotropic diffuse transmittance was prevailed while transmission of direct insolation was dominant above 0.5 clearness index. For south facing vertical plane SPD glazing transmittance in its transparent and opaque states are 0.25 and 0.025 respectively while clearness index is below 0.5.
