There are many factors that have a major influence on reducing the energy expenditure in building *** research aims at qualitative and quantitative assessment of those factors such as double glazed windows,ver-tical greenery systems(VGS),integrating of semi-transparent photovoltaic device with architectural design of buildings,energy saving by using heat reflecting coating,passive climate control methods,energy saving by shading,building energy performance enhancement by using optimisation technique,double skin green facade,*** a holistic and thematic *** the aforesaid techniques,VGS is found the most reliable,efficient and sustainable *** VGS can improve the urban environment,increase biodiversity,mit-igate pollution also results economic benefit of the buildings as like as energy savings and decreasing surface *** fundamental energy saving methods are used in VGS which are considered as passive energy saving ***,interception of solar radiation due to the shadow risen by the vegetation;secondly,vegetation also provides thermal insulation;thirdly,plants evapotranspiration helps for evaporative cooling of building;finally,building blockage makes a variation of wind effect on *** peak cooling load of ivy coated green building wall has been reduced by 28%.If a VGS is installed without windows and building fac-ing on west,east,south and north correspondingly,the reduction in the cooling load capacity of the building is observed to be up to 20,18,8 and 5%,*** high thermally resistive glazed areas on building envelope can be secured via thin film PV glazing and vacuum glazing products with an average U-value of 1.1 and 0.4 W/m 2 K,*** use policies are also helpful to improve energy consumption scenario of *** developing more energy-efficient,sustainable and eco-friendly buildings,these techniques might be helpful for the building designers and architect

green Walls as Mitigation of Urban Air Pollution:A Review of Their Effectiveness

引用

Research in Ecology 2023年第2期5卷 1-13页

作者： Kuok Ho Daniel Tang Department of Environmental Science The University of ArizonaTucsonAZ 85721USA

Mitigation of urban air pollution has been constrained by the availability of urban spaces for *** walls offer the prospect of greening spaces and surfaces without requiring large *** walls can largely be divided into green facades where the aboveground parts of plants rooted in soil and pots grow directly on,and living walls holding bags,planter tiles,trays and vessels containing substrates in which plants are *** facades and living walls can be continuous or modular with repeating units that can be assembled for *** review aims to present the effectiveness of green walls in removing different types of air pollutants in indoor and outdoor *** examined more than 45 peer-reviewed recently published scholarly articles to achieve the *** highlights that most of the studies on green walls focus on particulate matter removal and green walls could effectively remove particulate matter though the effectiveness varies with plant types,air humidity,rainfall and its intensity,leaf area index and contact angle,green wall surface coverage ratio,as well as the height of green *** the height of green walls and optimizing their distance from roadsides could promote the deposition of particulate *** off could regenerate plant surfaces for capturing *** walls are also effective in removing NO2,O3,SO2 and *** active living walls,when properly designed,could have air purifying performance comparable to a HVAC *** performance of green walls could be optimized through polycultures,selection of plants,surface coverage and height,and air inflow.
