Encontros e desencontros da iluminação natural : um estudo em espaços de internação hospitalar.

Abstract

The natural light presents countless advantages. Among them the variability, which serves as source of physiological and emotinal stimulation to the human being. In environments where people are interned in a hospital, the long stay and the physical vulnerability ask for not only efficient environmental conditions, but also capable of providing positive reactions in the patient recuperation. In Brazil, the norms that rules the hospital's projects don't talk specifically about the natural light subject. In this case, the levels of ilumination are treated throught the recomendations related to artificial lights. On the other hand, studies about the visual confort estabilish parameters throught the relations of brightness of the surfaces. Moreover, the National Policies of Humanizations of the Attention and of the Administration of the Unic Health System talks about the eviromental comfort as a priority, making it important to know, with the population that uses it, their opnion about the enviromental conditions. Before this context, this research has the objective of analyzing the patient satisfaction about the conditions of the natural ilumination and, specifically, evaluate the visual comfort considering the behavior of the natural light and its levels, the condition of the sky, the opennings, the use of colors on the surfaces and the visual needs. The studies took place at the Infirmaries 28 and 35 of the Hospital Santa Casa de Misericórdia de Maceió. The Evaluation Post-Occupation (EPO), method chosen by this evaluation, approaches a comparative analysis between the conditions of natural ilumination and the degree of satisfaction of it's users. The results show that the conditions to the visual comfort are not exclusively based upon estabilished quantitative indexes and that the user's visual satisfaction at infirmaries goes throught a series of aspects from the patient‟s clinical conditions and hospitalar routine to expectations and personal desires. Thus, it's hoped that this study is able to contribute in the discussion about the visual comfort and in the projectual process of hospital environments.
