The Research Of Rainwater Utilization System In Green Building

With the rapid development of urbanization our country, has created an unprecedentedmaterial and spiritual civilization, but also caused serious environmental pollution anddamage to ecological environment. The construction of water-saving society is animportant content of implement the scientific outlook on development and promoting theharmonious development of man and nature, and also a necessary choice to solve theshortage of water resources in our country. Among them, green building is the requirementof sustainable development and environmental protection, pursuit the harmony and unity ofnature, architecture and human harmony.In the "Green Building Evaluation Standard"water section, the use of non-conventional water resources is the green building rating in avery important part. Rainwater is a valuable non-conventional water resources, low rainfallthe water quality index, requires only a simple water treatment process, rainwater can beutilized. In this paper, the use of green building rainwater system for research on waterscarcity issues and play a role, has great practical significance.Based on the present situation of the use of rainwater and green building researchexposition and analysis, green building rainwater utilization system problems to be solved,and the use of rainwater from the green building principles and technical requirementsstarting on green building rainwater utilization system theory and technology, greenbuilding moderate rain water calculation method, the use of green building in the rainpattern three aspects of the research, and finally, Hebei Agricultural University, forexample, the design of rainwater utilization plan.For the study of green building rainwater utilization system theory and technology,the paper from green building assessment provisions relating to the use of rainwaterstarting rainwater utilization of basic theory and a variety of technical features andcomparative studies to explore the use of these technologies in green buildings rainwaterutilization system in the economic, social and environmental benefits. And the type ofgreen building rainwater utilization were divided, and the rainwater harvesting techniqueswere totalized and classification, so that in the design of rainwater harvesting projects onrelated technology selection.Rainwater can be collected to calculate the amount of rainwater is to choose aprerequisite for the use of technology and patterns. Firstly, the amount of rainwater utilization of various calculation methods were compared and studied abroad, then adistrict of Baoding, Hebei Province, for example, is calculated using a variety of methodsto calculate the amount of rainwater can be collected, analyzed by calculating the finalresults of the analysis of various Features method of calculating the amount of rain.This paper also different scale public buildings and residential buildings, fullyfamiliar with the various methods of rainwater utilization is proposed based on a morecomprehensive scale of different buildings, different building types of green building watersystems for rainwater utilization patterns in. Thus, making green building design, buildingtype and size can be based on direct selection of the appropriate use of green building inthe rain pattern design.Green building is an important way to achieve a water-saving society, the use ofrainwater is an important indicator of the evaluation of green building in the use of greenbuilding in the rain with the reality of the economic, social, environmental and othermulti-benefits. Therefore, the study of green building rainwater utilization system is veryimportant.
