Thermal investigation on the attics of buginese traditional houses in South Sulawesi

Abstract

Abstract This study aims to investigate the thermal conditions of the attic of traditional Buginese houses in the climate of South Sulawesi. The analysis is carried out based on data surveyed from eight houses. The recorded data includes both attic internal weather data and the measured environmental weather starting at 08.00 to 16.00 Central Indonesia Time (CIT). Measurement results showed high temperature in the attics, ranging from 30.7 °C in the morning to 51.1 °C in the middle of the day. Relative humidity minimum of 17.3% at midday and the highest is 67.1% in the morning. The roofs temperature can reach 67.7 °C before midday. The temperature on the attic floor between 24.9 °C in the morning to 43.0 °C in the middle of the day. The difference in the surface temperature of the attic floor guesses to be an average of 1 °C higher than the ceiling surface. Environmental weather factors have the most dominant influence on attic thermal performance.
