Modelling hygrothermal conditions of unsaturated substrate and drainage layers for the thermal resistance assessment of green roof: effect of coarse recycled materials ; Belgium

peer reviewed ; Alternative materials exist for green roof layers: secondary resources like coarse or fine recycled aggregates may be used as a substitute to natural materials. For using these new types of materials, it is needed to assess their heat resistance which is performed according to ISO 9869-1 standard. Moreover, the initial hygrothermal conditions of unsaturated substrate and drainage layers have also to be modelled and assessed for optimizing the layers’ thickness. In this study, the green roofs with unsaturated substrate and drainage layers incorporating coarse recycled materials... Mehr ...
