Measured bidirectional transmittances and reflectances of a buff-coloured venetian blind together with a layer calculation scheme developed in previous publications are utilised to produce directional-hemispherical properties for the venetian blind layer and solar heat gain coefficients for the blind in combination with clear double-glazing. Results are presented for three blind slat tilt angles and for the blind mounted either interior to the double glazing or between the glass panes. Implications of the results for solar heat gain calculation are discussed in the context of solar positions for St. Louis, Missouri.
