ILUMINAÇÃO NATURAL EM SALA DE DESENHO: UM ESTUDO NO SEMIÁRIDO PARAIBANO

Abstract

The quality of learning environment is associated with the degree of comfort that the environments offer and aspects of natural lighting are relevant. In this paper, the impact of shading devices in a south facing drawing classroom located semi-arid region of Brazil was evaluated. It compares annual simulations for five models with different static shading device. The analysis is based in dynamic daylight performance metrics such as Daylight Autonomy (DA) and Excessive Useful Daylight Illuminance (eUDI) and simulations were performed by software Rhinoceros and Diva-for-Rhino plugin. Therefore, the daylighting autonomy and excessive were employed with illuminances between 500 lux and 3000lux and in solstice periods. Results show that levels reached minimum illuminance recommended by NBR ISO/CIE 8995-1:2013. Finally, louvres and light shelves inclined at 15º and 30º offer higher autonomy and increasing the possibility of glare and heat gain near the window. However, the shading device smaller 15º decreased the direct sunlight and provided homogeneous illuminances throughout the room.
