ることができる。According to the rooftop planting base of the present invention, the soil of the porous plate made of porous concrete placed on the waterproof layer is filled with soil for planting, so that the planting plant can be directly planted on the porous plate. It can be planted and construction is easy. The relatively large size of the aggregate and the gap on the upper surface side of the porous plate can reduce the heat transfer coefficient on the outer surface side of the roof and improve the heat insulating property. Can be maintained, and the planted plant can be suitably grown. On the other hand, since the aggregate and the gap on the lower surface side of the porous plate are formed relatively small, the heat capacity on the inner surface side of the roof can be increased and the heat retention can be improved.
