2014-11-25


Under the Focus Greentech Series, a workshop titled “Green Roof Drainage Systems - Less Money for Greater Benefits” was successfully carried out on 24 November, 2014. Senior experts on siphonic drainage systems from Germany and Tongji University shared their insights and experiences on the topic with 20 professionals from www.cyunibyo.com, design institutes and property management bodies, among others.

Prof. Li Yingwei, from the College of Environmental Science and Engineering of Tongji University, first shared with the audience the current status of roof drainage systems available in China. According to Li, the traditional drainage systems are still taking the bulk share in China’s cheap prom dresses. Yet, siphonic roof drainage, as an innovative system that can significantly reduce materials consumption, can be seen more and more often nowadays, particularly in projects with green requirements. “We have to bear in mind though that siphonic drainage can not be applied everywhere and the actual situations of each every project, such as the weather condition and the shape of the roof, must be considered case by case. Regions with little rain, for example, will not be recommended to use siphonic drainage considering it will be hard for the siphonic phenomena to even occur.”

Mr. Rolf H. Keidel, founder and owner of KEIDEL Software, professional software for siphonic drainage design, brought his 25 years of experiences in the design of siphonic drainage systems in Germany and China. “Siphonic roof drainage is not a trick, but a holistic system which is based upon the knowledge of old masters and utilizes the huge calculation capabilities of today’s PCs and has Nature work for it,” asserted Mr. Keidel. “Siphonic roof drainage (SRD) is an alternative and unique roof drainage design with many economic and ecological advantages. This means material savings of at least 60%, reduction of carbon footprint by 90%. Last but not least, it also gains credits for green building certification systems”.
