Abstract
A system for harvesting rainwater for use in a skirt building. The skirt building includes a main building and a podium supporting the main building. The system includes: a standpipe; a buffer channel; a filter channel; and a green roof. The green roof includes a vegetation region including a baffled diversion corridor, and a bottom filtering layer including a drainage pipe. The standpipe is arranged on the main building and is connected to the buffer channel where the energy of rainwater flowing out of the standpipe is dissipated. The buffer channel, the filter channel, and the green roof are arranged on the podium, and the buffer channel communicates with the filter channel. The filter channel is connected to the green roof. The filter channel is divided into a plurality of sections respectively filled with different matrix materials.
