Avaliação da iluminância de uma sala de aula típica do IFMG campus Ipatinga

Abstract

The lighting of internal work environments is regulated, in Brazil, by occupational hygiene standard nº11 (NHO Nº11) which, among other criteria, establishes the average level of illuminance according to the type of environment and the kind of activity and/or or task all developed. Furthermore, it also presents the technical procedures that must be used in the development of a lighting project for a place, in addition to good lighting and visual comfort for workers. However, although there are standards and procedures for the evolution of a project, ideal lighting levels are not always obtained for the premises. Therefore, excessive or insufficient lighting causes, over time, problems with the employee's health, as well as situations with a risk of accidents and poor performance of tasks. In this circumstance, this work aims to evaluate the level of lighting in a classroom at the Federal Institute of Minas Gerais in Ipatinga, considered a space where students and staff spend most of their time carrying out their activities. To this end, illuminance measurements were carried out in situ of the existing room design. Subsequently, simulations were developed in the DIALux Evo software with 3D model representations, which will present an ideal lighting design for the environment based on its purpose
