A INFLUÊNCIA DAS ORIENTAÇÕES DAS ABERTURAS E CONDIÇÕES DE CÉU NOS NÍVEIS DE ILUMINAÇÃO NATURAL EM UM AMBIENTE HOSPITALAR

Abstract

In Brazil, the capture of natural light is one of the main strategies in the search for more welcoming, comfortable and humanized environments, avoiding confinement and contributing to the healing process of patients in healthcare facilities. Among the parameters that can determine the natural lighting conditions in these environments, there are the orientation of the openings and the sky conditions. In this context, the objective of this study is to compare the influence of various guidelines on the levels of natural lighting in hospital admission rooms in Maceió-AL. This is a case study, classified as an exploratory study. Based on the existing technical specifications at the site, a computational model was developed for simulation in the Troplux 6 software. Thirty-two groups of simulations were performed with orientations that varied every 11.25°, in four sky conditions: covered, partially covered, clear and dynamic, on all days of the year. Charts in circular histogram format present the average annual illuminance values relative to each of the orientations. The results show high annual percentages of illuminance in the excessive frequency range. It can be inferred that the use of sunscreens is necessary for any orientation in front of the environment presented. The types of sky conditions and the orientation (linked to the geographic location), when considered together, can interfere with the quantity and quality of natural lighting. Studies that address the quality of natural lighting, together with quantitative analyses, may contribute to the proper design of future projects for healthcare facilities.
