Abstract

This research aimed to study the appropriate type of roof for residential buildings in hot and humid climate. There were 3 types of roof: Gable roof, Hipped roof and Lean to roof. Only 30◦ of tilt angle for all roofs were considered. The study also focused on concrete tile and metal sheet roofing materials. Furthermore, a comparison of solar absorption at 0.6, 0.4 and 0.2 and equipped with ceiling insulation were investigated. Heat transfer through roof was calculated using TRNSYS 17 program. The results showed that amount of heat transfer through metal sheet roof performed more than concrete tile by 29.26% for Gable roof, 25.38% for Hipped roof and 35.07% for Lean to roof. In term of solar absorptivity of materials, in case of solar absorptivity of 0.6, the heat gain into building was more than a case of 0.4 and 0.2 at 25.24% and 50.48%, respectively. The Gable roof with concrete tile of solar absorption of 0.2 performed a very low heat gain at 3,614.4 kWh
