DESEMPENHO TÉRMICO E CONSUMO ENERGÉTICO EM UMA SALA DE AULA PADRONIZADA

“IMPACTO DO MODELO DE JANELA EM DUAS CIDADES DA ZB 8”

Abstract

The standardization of school architecture in Brazil is worrisome from the point of view of environmental comfort, as most of the time it does not take into account the climatic particularities of each place, resulting in environments with thermal discomfort and consequently energy expenditure with refrigeration systems. According to NBR 15220, one of the main passive strategies for thermal conditioning in locations located in Zone 8, characterized by a hot and humid tropical climate, is the ventilation of the environment, which intensifies the role of the building's windows in capturing and distributing air. Thus, the objective of this research was to evaluate the thermal comfort in a standard classroom of the Proinfância Tipo B school project, evaluating four different window design configurations. In addition, the energy consumption and the annual financial cost were calculated to provide comfort, artificially, at times when it is not reached passively. The method performed involved computational simulations using the DesignBuilder software. The results show that the window (M4), which offers a larger area for ventilation and higher rates of permanent air intake (24 h/day), through the ventilated and pivoting sill, presents better thermal performance in all the studied configurations, in contrast to standard window (M1) has the worst performance. It was also evident that by associating increased ventilation with the correct orientation of the classroom façade, maximum performance is achieved.
