The abundance of heat-trapping asphalt and concrete, smog, and heat emitted from buildings and vehicles is one of the major reasons for the prevailing high temperature, air and noise pollution in cities. Incorporation of green wall in buildings is considered to be an effective method to reduce temperature and mitigate environmental pollution. This study investigated and compared the performance of two types of climbing green wall (CGW) and paving green wall (PGW) vegetation for temperature and noise reduction. Besides, the biological characteristics of Parthenocissus tricuspidata and Sedum lineare Thunb were also analyzed to substantiate the temperature and noise reduction performance of these plants. The results revealed that, the average temperature reduction by CGW and PGW were 4.9% ± 1.3% and 16.6% ± 7.4%, respectively, under no irrigation condition, and 18.4% ± 9.4% and 23.8% ± 8.7%, respectively, under irrigation condition. The noise reduction by CGW in high (75–80 dB), medium (50–55 dB) and low (30–35 dB) sound pressure level was 12.4, 7.5 and 5.7 dB, respectively, and 15.6, 9.3 and 7.0 dB, respectively, by PGW. The results demonstrated that green wall has an excellent effect on buildings toward temperature and noise pollution reduction.

大量吸热的沥青和混凝土、烟雾以及建筑物和车辆排放的热量是城市普遍存在高温、空气和噪音污染的主要原因之一。在建筑物中加入绿化墙被认为是降低温度和减轻环境污染的有效方法。本研究调查并比较了攀爬绿墙 (CGW) 和铺路绿墙 (PGW) 两种植被在降温和降噪方面的性能。此外，三尖瓣和景天属植物的生物学特性还进行了分析以证实这些植物的温度和降噪性能。结果表明，无灌溉条件下CGW和PGW的平均降温分别为4.9%±1.3%和16.6%±7.4%，灌溉条件下分别为18.4%±9.4%和23.8%±8.7%状况。CGW 在高 (75–80 dB)、中 (50–55 dB) 和低 (30–35 dB) 声压级的降噪分别为 12.4、7.5 和 5.7 dB，以及 15.6、9.3 和 7.0 dB，分别由PGW。结果表明，绿化墙对建筑物降低温度和噪音污染有很好的效果。
