Abstract
The aim of this experiment is to study the effect of light distribution in scale models of a real classroom due to different light shelves.
The construction of scale models of a classroom of the TEC´s Campus Tecnológico Local San José was carried out with taking the color of the ceiling as variable and maintaining its shape. For the cases of study, the performance of light shelves was analyzed to measure distribution of natural lighting coming from the window to the farthest spaces of the classroom, as well as their effectiveness as solar protection.
Three time slots were analyzed, morning, noon and afternoon, during December 2018 to January 2019, taking lighting measurements outside and within the scale model. The analyzed variables can be summarized as: color of the ceiling, shape of the light trays, and color applied to the walls and surfaces of the classroom.
From the results obtained, it is concluded that there are still large gaps in the understanding of how to achieve a uniform distribution of lighting inside a room, avoiding high visual contrasts, this is especially important in a classroom where there must be a priority in the visual comfort of its users. The specific use of flat light shelves showed effective both as a sunscreen element and to redirect light to spaces far away from the window.
