Melhoria nas condições de iluminação do acervo da Biblioteca Central da Universidade Federal de Santa Maria

Abstract

An illumination system for the underground floor - West, East, North and South Wings - of the Main Library of the Federal University of Santa Maria is proposed, based on Iluminância de Interiores (NBR 5413) and Norma Regulamentadora do Ministério do Trabalho: Ergonomia (NR17). A 300 lux of uniform vertical illumination is designed for book stands. For the reading, computer facilities, periodical sections and administrative rooms, a 500 lux of horizontal illumination at a 80 cm working distance level is proposed. Effects of luminosity, coefficient of reflexion and cavity zones on ceiling, wall and floor are also considered. An installation of ultraviolet radiation filter and adaptation of luminaries between book stands are also suggested. Finally layout of luminaries, its cost, and comparisons between present electrical load and the proposed one, are also presented.
