ABSTRACT: The evaluation of daylight admittance through openings of solar control devices – SCD – is not a simple task, for the addition of obstacles near the opening modifies the quantity of daylight transmitted, as well as its trajectory to the interior. This paper shows the results of parative analysis of the luminous performance of openings plex SCD pared with others of differentiated geometry but with the same solar protection angle. A method analogous to a goniophotometer used in photometric studies in the laboratory was developed for this analysis, putational simulation from a spatial representation virtual model of the inner environment. The method was implemented with the use of the APOLUX putational simulation program (validated), identifying admitted luminous flux and daylight spatial distribution under the interference of the SCD. Regarding the admitted luminous flux, for example, for a solar control device of 10 horizontal pared to one with 1 horizontal slat, there was a 3 to 6 times increase. The method developed permits the evaluati
