| Since the energy problem and environment problem, the construction energy conservation extensively developed in the countries all over the world. As one of the strategies, vertical greening in the last few years in the application. Domestic understanding of building three-dimensional greening, only more than stay in the form of vine climbing the building wall metope direction, there is a common narrowness, therefore, the development is relatively lagging and single. And as essential water irrigation in the rendering of urbanization becomes more and more serious in modern times, in short supply becomes one of the most serious problem,therefore, the rainwater collection and utilization of the unconventional water resources becomes the focus of attention. How to use rainwater collection in stereo virescence is this problems for study.First of all, based on the new urbanization under the background of the rain flood problems and green low carbon way of life as the research background, and sums up the present situation,the system introduces the influence of facade of stereoscopic greening rainwater processing,clear related concepts. At the same time, through data collection and case investigation,understand the relevant design methods and the application of new technologies at home and abroad, concludes the passive rainwater collection system with the emphasis of the rainwater harvesting system is different, summarizes its developing tendency.Secondly, the article respectively with two chapters to study from two categories: one is longitudinal vertical greening rainwater to use; 2 it is transverse stereoscopic greening rainwater to use. Its classification is according to the proportion the main drainage system of the passive green part of the size, in particular, vertical greening focus on using the passive form of rain,focus on using the active lateral greening form rain. And in view of the content of each chapter further classification, chooses the rain takes into account the economic principles of greening,rain water system treatment measures and plants selection and maintenance and other factors,make the combination of building green and rainwater system can better, and make it on the basis of form, to ensure the concrete construction practice, let building three-dimensional greening brought rain had practical technical level. At the same time, the practice of the German werder Bremen youth apartment design case interwoven, and further analyzes the rainwater collection and building three-dimensional green landscape design to synchronize unification consideration of rainwater ecological strategy, but also demonstrates the argument put forward by the mentioned above is feasible.Finally, based on the research results on paper, and puts forward the future rainwater collection using the application in building 3 d design will be transformed into "can make the rain resources in greening cycle", and from the cycle of "single building small scale" to "cycle ofcomplex large scale". |
