Análise do desempenho da iluminação natural de salas de aula de desenho em Vitória (ES)

The energy crises in several countries, including Brazil, boosted the need to revise the energy consumption. The buildings are responsible for much of the electricity consumption. In Brazil, about 20% of this consumption is for the lighting environments. The use of natural light favors both reducing energy consumption and improving comfort conditions. In a school environment, the quality of learning is a direct function of the degree of environmental comfort presented by space. In this case, appropriate illuminance combined with a uniform distribution of light are essential to student achievement. Thus, this paper aims to analyze the performance of daylighting four drawing rooms located in Vitoria (ES) in order to verify the conditions of comfort that users are subjected. This analysis was performed by comparing the results of in situ measurements of illuminance, following the NBR 15215-4, and the perceptions of students collected through a questionnaire based on previous work by other researchers. The results indicate that the system of natural lighting of the rooms is insufficient to promote luminal
