Nowadays, ultra-advanced facades have made great strides, and parametric simulation software has made a significant contribution to this advancement. Voronoi shells, based on their irregular nature, are one of the most advanced facades that are being used in modern building facades. In this paper, the main focus is on the behavior of these facades against incident light from the sun. The method presented in this research is based on Ladybug Tool’s plug-in capabilities. Using the analysis of weather information and the desired geometry, direct rays as a vector in each time step is prepared, and the amount of direct sunbeam hours by considering the contexts (Facade) calculated. To estimate the comprehensive method, the same workflow evaluated winter (P2) and summer (P1) solstice as a cross-sectional study (Max & Min solar altitude). The results indicate that the type of geometry Voronoi and the thickness of the facade frame have a great effect on the direction of the rays inwards and also the type of geometry should be controlled at latitudes appropriate to the solar altitude; because of the geometric intricacies of the Voronoi facade have a great deal to do with the solar altitude.
