Experimental Study of the Thermal Insulation Property of Sedum Linear Roof Module in Real Weather Condition in Guangzhou, China

Abstract:

In this paper, four typical building roof modules, i.e., sedum linear module, lightweight planting soil module, water-retaining board module and XPS module, were experimentally investigated by using the guarded hot box under real weather condition in Guangzhou, China. The testing results were compared and analyzed regarding to three main properties of the roof module, i.e., the top and bottom surface temperatures of the modules, air temperature inside the inner box of the guarded hot box and temperature attenuation characteristics for the thermal insulation of the modules. It was found that the sedum linear module performed well in the thermal insulation property under the typical summer weather condition. The analysis results could be used to assist in the application of the green roof module, and contribute to the energy conservation of the buildings.
