POTENCIAL DE MELHORIA DE DESEMPENHO TÉRMICO DE AMBIENTE RESIDENCIAL POR MEIO DA ADAPTAÇÃO SAZONAL DE ELEMENTOS DA JANELA EM CLIMA SUBTROPICAL ÚMIDO

Abstract

Facade adaptation can improve the thermal performance of a building by modifying it in response to variable environmental boundary conditions. The windows are important elements for the heat exchanges between the internal and external environment of a building, being their configuration, often determinant for the internal thermal conditions. Given the possibility of seasonal adaptability of window systems, these can make up the climate-adaptable façades. Thus, the present study aims at the potential of thermal performance improvement by the seasonal adaptation of windows elements in a residential environment under humid subtropical climate. Heating, ventilation and air conditioning (HVAC) systems were not employed. The research was based on results of a thermal performance simulation of a room with seasonal adaptation of the facade opening percentage (PAF), blind closing set-point and ventilation schedule. The adaptive model based the calculations of thermal discomfort hours inside the model. The results showed potential of reducing the hours of thermal discomfort by the seasonal adaptation of the PAF and blind closing set-point for the ventilation conditions adopted.
