Análise de iluminância em ambientes de sala de aula do curso de Administração da UFCG.

Abstract

The ergonomics searchs to adapt the context of the environment of work to the man, aiming at with this to propitiate better physical and psychological conditions for the accomplishment of its work and activities to it. The educational sector is an area where the ergonomic contributions can contribute for the improvement of the process and allow the increase of the pertaining to school productivity and the satisfaction of the main involved actors in this activity: professors and pupils. In the environment of classroom, the illumination is decisive factor. The iluminamento level influences in the perception, the income and the visual fatigue of the users. With this one searched to make a illumination techniques study of the classrooms of the course of Management of the UFCG. The study it was of the exploration type, with quali-quantitative boarding. As instruments of collection of data they had been used: comments “in-I lease”, measurements made with light intensity meter digital D401025 (mark DAVIS), trena and digital photographic machine (Olympus mark D-390 model). For analysis of the data, the method of lúmens and recommended for the NBR 5413/1992 and NBR 5382/1985 had been used. It was possible is evidenced that the searched rooms present, in its totality, some type of disconformity or situation that lacks of corrections. The problems turn, basically, on: light bulbs with bad functioning or forest fires; differences of enter the types of light bulbs; existence of shade points; amount of superior light bulbs to the necessary one with consequent increase in the energy consumption. The rooms, during the night, present inferior averages of at least equal iluminance or to the established one for NBR 5413. As recommendations, I suggested alteration in the amount of light bulbs, what it could offer a reduction of about 20% in the consumption of electric energy. So that this economy in fact was reached, other factors would have that to be taken and consideration. Among them we can detach: change in the layout of the position of the lights; alteration in the colors of the environment, opting to colors that favor the iluminance; e regular cleanness of the light bulbs and lights. This research allowed to observe the great importance of the application of the ergonomics and the illumination in the environment of classroom, being, clearer the consequences of these, in the educational performance and the way as it intervenes with the 12 health of the users. Based in this, one expects that the variable treated in this work are thought and seen for responsible by the education as a possibility of improvement about the quality of education without for this it is necessary to expend great investments in view of the benefits that will be conquered. It can be concluded that the application of ergonomic principles is possible and that it will result in benefits that will become the act to learn and to teach more pleasant, satisfactory and efficient.
