生态工程 绿色屋顶和绿色垂直墙面

Ecological Engineering Green Roofs and the Greening of Vertical Walls of Buildings

绿色屋顶和绿色墙面可以增强保温效果即夏季保持凉爽和冬季保温,增强视觉美感,改善室内外微气候环境,吸附氧化氮和悬浮粒子以及为鸟类和昆虫创造栖息地来增强生态价值;文章在生态工程的背景下展示绿色屋顶和绿色室外墙面的影响力,并质疑对采用绿色墙面作为建筑外层迟疑不决的做法;特别提到悬浮微粒、浮尘沉积与植被的关系。概括并比较了住宅建筑及工业和其他商业建筑墙面绿化的不同种类,并通过具体例子来展示多功能的可能性;还展示了如何组织大型绿色建筑的实施,使绿色墙体作为综合设计的一部分,确保其从设计概念到建成后日常维护期的可行性。

Greening of outside walls and roofs of buildings has been used for their increase of insulation （keep cool in summer and keep cold out in winter）, improved aesthetics, improved indoor and outdoor climate, catching of NQx and Particulate Matter （PMx）, as wes as increasing ecological values by creating habitats for birds and insects. The paper will show within an ecological engineering context the impact of green roofs and the greening of outdoor walls and question the hesitation to implement green wails as outer layer of buildings. Special attention will be given to the relation between particulate matter and aerosol deposition and vegetation. An overview and comparison of different types of wall greening for housing as well as for industrial and other commercial buildings will be given. Some concrete examples will be elaborated to show possibilities of multi-functionality. The paper will also show how to organize a program for large scale implementation of green building envelopes as integrated approach in order to make greening of walls feasible from the design concept till the maintenance phase.
