Applied Research On Stereoscopic Greening Of Building In Xi’an

The "Silk Road Economic Belt"(SREB) was first proposed by Chinese President Xi Jinping in a speech delivered at Nazarbayev University on September 7,2013.Xi’an as the starting point of the "Silk Road" and the important point of "Silk Road economic belt" will give full play to the historical, geographical and logistical advantages to reproduce ancient capital of glory and splendor in SREB practice with low-key,pragmatic and work hard. The urban green area need to increase with the rapid development of Xi’an, but the city’s land is limited.In recent years, it serious impact on people’s production and life as the serious pollution and haze weather frequency of Xi’an.Therefore, it is an important means of development of Xi’an to development of greening and improve the urban environment. Stereoscopic greening of building can effectively increase the rate of urban greening and improving the urban environment because it can take advantage of three-dimensional surface area of the buildings.The building’s indoor stereoscopic green as a kind of form of stereoscopic greening of building can improve the indoor environment and the living environment of Xi’an,create a suitable indoor environment.This paper first analyzes the climatic characteristics of Xi’an region and expounds the common forms and the concept of the stereoscopic greening of building.Analysis of the main role and the present situation in the construction of the stereoscopic greening in Xi’an area. It raised some issues for the current development of the stereoscopic greening of building in Xi’an.Secondly, through numerical simulation software Fluent to simulate the indoor plant wall building the temperature and velocity field in spring and summer, while no interior plant walls in the building were simulated.Comparative analysis of the simulation results with indoor plants walls and not plants of the wall can be drawn houseplants can reduce the indoor temperature, indoor plants in spring can reduce the temperature of 0.8 ℃,summer can be reduced 1.7 ℃.Through testing the second layer(no indoor plant wall) and third layer(indoor plant wall) indoor temperature and humidity changes in spring and summer for a hotel in Xi’an.By analyzing the measured data, we can seen in the summer there is the plant wall surface temperature is lower than the wall without of 4.9 ℃and the maximum reduction of the indoor temperature 1.8 ℃. The plants wall of the building’s relative humidity was 14%higher than the building without plants wall.The green plants can effectively increase the indoor humidity.Finally, thesis put forward their own proposals according to the present situation of the development of stereoscopic greening of building and provide a reference for the development in Xi’an area.
