Acoustic and Luminous Performance Evaluations in Classrooms in Curitiba, Brazil

Abstract

This study deals with a standardized project in public schools in the Brazilian State of Paraná and analyzes acoustic and luminous qualities in classrooms. The acoustic analysis, conducted by measurements of background noise, reverberation time, and sound insulation, reveals the poor acoustic quality of the classrooms. Acoustic simulation results suggest the need for perforated plywood underneath the ceiling to reduce reverberation time and increase the overall acoustic comfort of the classrooms. The luminous performance analysis is based on computational simulations with daylighting programs for different combinations of days, schedules, and solar orientation of the buildings. Results show daylighting levels for various positions of the building. This allows the designer to choose the best way of siting the building with respect to aspects of the locality and the resulting quality of the indoor space. Finally, shading elements are designed for each orientation in order to improve daylighting levels and the building's overall thermal performance.
