This paper introduces a new approach of collecting rainwater on building roofs based on the diversion of rainwater in roof drainage pipes. A case study for a fiat - topped apartment building in Chongqing is presented, in which every room was equipped with the diversion system. The cost of the systems was about￥ 1.59 per square meter, and might be recovered in about 2.2 years. The rainwater harvesting system shows advantages because of its simple structure, environmental materials, low cost, and considerable economical benefits. The systems may provide a promising way of the roof rainwater utilization for green building tech- nology.
