Over the years new technologies and materials adopted in the buildings structure and composition have contributed to the development of modern concept buildings and the access, not always desirable, of light and heat. In Brazil, the great availability of daylight allows the creation of projects which use this environmental factor. On the other hand, excessive solar radiation, when uncontrolled, might damage the users’ thermal and visual comfort, through excessive heat gains, contrasts and glare. The solar shading elements begin to be apprehended as a possible solution to control the direct solar incidence on buildings. In Health Assistance Establishments, where lighting is a key element to avoid the confinement inside the rooms and to help on the patient’s cure process (users), the brise-soleil might represent an aggregator element in the search for more humanized internal spaces. In this context, this work aims to evaluate the luminous performance of mobile vertical sunshades on the daylight of a hospital collective stay room (adult infirmary) in Maceió (AL). To achieve the goal it was used as a tool the computer simulation software TropLux 6, three distinct angulations of the slats were proposed, with three different colors of finishes, in four orientations (North, South, East and West) and with different sky conditions (clear, overcast and partly cloudy). The simulation was accomplished considering all the days and months of the year, from 8a.m. to 4p.m. The provided results allowed checking the conditions of daylight as to the influence on the position of the blades, distribution and useful daylight illuminance inside a room, performing a quantitative and qualitative evaluation of the sunshade’s efficiency on the case study. Therefore, it is intended to broaden the studies, as to the inclusion of mobile vertical solar control elements in Health Assistance Establishments (hospitals).
