Abstract: The first working environment of the human being, the classroom, should be a comfortable
place for learning to happen with the greatest possible margin of achievement. The classroom
environment of an architecture college needs, in addition to be comfortable, with good lighting
conditions for the realization not only theoretical classes but also to design projects. The model used
for this study purposes is a classroom in the award‐winning Modernist building of the Architecture
and Urbanism Faculty, headquarters of the Federal University of Rio de Janeiro, with a rectangular
floor plan and glass doors that lead to a balcony, where natural light penetrates. The use of natural
lighting contributes to reduce the use of artificial lighting system and consequently to the building
energy waste, contributing to user satisfaction. The research aims to analyze the natural lighting
performance, through computational simulations methodology, based on software NatLite and
RadLite, programs developed at the same university. The use of light shelves will also be studied,
improving energy efficiency. Thus it is desired to evaluate the impact considering energy efficiency
and user needs, as well as study classrooms design possibilities according to the climate. The results
of the simulations will then be presented and discussed.
