The Research On Vertical Greening In Office Building Exterior Environment

Today, China is in a period of rapid urban development, the city gathered in high-rise buildings, highways, vehicles are also more and more, and can be less and less green space, PM2.5pollution is getting worse, how to improve urban environment is imminent, and vertical greening let us hope. In the case of urban land shortage vertical greening is particularly important, we can take advantage of building walls roofs, balconies and other places another green environment, it can greatly supplement the ground greening, increasing urban green coverage area, thereby improving the city residents living environment. Visible, the implementation of vertical green building has become increasingly important in the external environment.Based on this background, I choose to study and discussion of the topic, by type of building space to explore a function of external environment, according to its spatial characteristics can be obtained using vertical green form, then all forms of vertical greening outside the building environments to explore in detail the specific application, mainly for in-depth study in technology, and the impact of the plant, such as the built environment. Through this study, lead people to pay attention to the environment outside the building, and the corresponding suitable for China’s external environment vertical green building recommendations and strategies. In office buildings for the study, based primarily on office buildings in an urban environment to the proportion of major office buildings and people’s daily lives, about one-third of the time people stay in office buildings were. Seen, good or bad office building environment on people’s health or not is very important. By studying vertical green office buildings in the external environment, the results of a more systematic vertical green office building in the external environment of the application model for workers in the future need for vertical greening in office buildings, providing basis. Through literature theoretical research, field research, analysis and other methods summarize the main draw the following conclusions:(1) Office buildings and outdoor environment can be divided into the entrance plaza, courtyards, roof garden, building skin, the four types of space. Office building exterior environment can use the vertical greening There are seven main forms, including green roofs, green walls, balconies (sill) green, green flower with scaffolding, fences and fence green, green slope, green overpass. Greening in the wall, using a fixed support structure or planting tray of green plants are mainly straight-walled container greening systems, modular vertical greening systems, lawn blanket of green systems, non-woven nutrient solution greening system four systems. In the application of the plant, summed up the various forms of vertical greening plant varieties. Wherein the straight-walled container greening systems commonly used plant species,12species of green vertical modular system used14species of plants, lawn blanket of green systems commonly have13kinds of plants, non-woven nutrient solution greening systems commonly have18kinds of plants.(2) vertical greening in the application of new technologies to consider not comprehensive enough. On the application of new technologies, it is an important consideration is the Structure and properties of materials, distribution mechanics. Leading to the design of a misunderstanding, that structure-based design of the composition, ignoring the growth characteristics of plants and construction considerations.
