Abstract
Roofs receive the most intense solar heat load among all building envelope surfaces in Equatorial-region. Solar heat gain through roof contributes to a significant portion of building heat load. In tropics where building cooling is needed all-year-round, passive methods to reduce heat gain through roof could provide significant cooling energy-savings.
Approach: Currently, the most widely adopted practices to curb the heat flux through roof include using thick building material-layer (30-40 cm-thick concrete) or insulation (5-10 cm-thick). This study investigates the thermal performance of emerging methods: cool roof and green roof. Cool roof works by applying a coating-layer having high-solar-albedo. Green roof works by adding a soil-layer and vegetation. This study numerically compares the heat curbing performances of these technologies under the tropical climate using an experimentally-calibrated.
