Estudo de caso em ambiente urbano: simulação computacional na análise da iluminação natural em uma edificação unifamiliar

Abstract

This study evaluated natural lighting in a residential building according to the NBR 15575­1:2021 standard. Natural lighting is important for visual comfort and energy efficiency in buildings. Theoretical concepts and evaluation methods, including computer simulations, were presented. A residential building was modeled using the DIALux software, and simulations were conducted on different days and times. The residence met the minimum requirements for illuminance and daylight factor established by the standard. The arrangement of rooms, building orientation, and use of openings contributed to an adequate distribution of natural light. However, the Home Office room did not meet the minimum lighting requirements set by the NBR 8995­ 1:2013 standard for work environments. The study highlighted the importance of evaluating natural lighting in residential buildings but also emphasized the need to consider specific standards for work environments.
