Cooling Effect of Waste Fiber Culture Medium Used as Extensive Green Roof

Article Preview

Abstract:

Greening on roofs that are not totally used can create a good cooling effect and mitigate the urban heat island effect. Considering the load capacity of roofs and ecological protection, this study thus uses fiber waste to make culture mediums as an extensive green roof, after which sedum makinoi is then planted to evaluate the cooling effect of the waste fiber culture medium. The experimental results show that sedum makinoi planted with waste fiber culture medium can averagely reduce the temperature of the roof surface by 5 °C and to a maximum of 11.8 °C. Although experimental group and control group both have the same cooling effect, waste fiber culture medium which is much lighter than that of the control group, and it also has a life-cycle, an energy-saving, ecological friendly merit, both of which qualify it for use of the culture medium as extensive green roof.
