Green walls have previously demonstrated the capacity to reduce particulate matter (PM), noise pollution, and temperature conditions in manipulative experiments and computational models. There is, however, minimal evidence that green walls can influence ambient environmental conditions, especially taking into account the variable environmental conditions encountered . The aim of this paper was to determine if green walls have a quantitative effect on ambient air quality in an urban environment. Ambient PM, noise, and temperature were recorded at 12 green wall and adjacent reference wall locations across a dense urban centre, over a 6-month period. The results indicated that PM levels and temperature did not significantly differ between the green wall and reference wall sites. Ambient noise at the green wall sites, however, was significantly lower than at the reference wall locations. It is suggested that mechanically assisted, or 'active' green wall systems may have a higher PM and temperature reduction capacity, and if so, they will be more valuable for installation compared to standard passive systems, although this will require further research.
绿色墙壁此前已经在操作实验和计算模型中展示了减少颗粒物 (PM)、噪声污染和温度条件的能力。然而，几乎没有证据表明绿色墙壁可以影响环境条件，特别是考虑到遇到的可变环境条件。本文的目的是确定绿色墙壁是否对城市环境中的环境空气质量有定量影响。在一个密集的市中心，在 6 个月的时间里，在 12 个绿色墙壁和相邻的参考墙壁位置记录了环境中的 PM、噪声和温度。结果表明，绿色墙壁和参考墙壁位置之间的 PM 水平和温度没有显著差异。然而，绿色墙壁位置的环境噪声明显低于参考墙壁位置。有人认为，机械辅助或“主动”绿色墙壁系统可能具有更高的 PM 和温度降低能力，如果是这样，与标准被动系统相比，它们将更有价值进行安装，尽管这需要进一步研究。
