Original Abstract

Shading obstructions and influence of their surfaces on daylight simulations in simulation tool Světlo+ was studied. The luminance ratio values were determined on basis of daylight measurements on models. The measurement data were compared with the simulation outputs. The comparison of the results is useful for correction of the standard luminance ratio for dark shading obstructions. It was proven that the standard value of the luminance ratio is overestimated for some designed cases. The correct specification of luminance ratio values is important for daylight factor calculations.in software Světlo+.
