“…There are several nomenclatures to explain biowall terminology and these include vertical gardens [5], active living walls [6], and green walls [7,8,9,10,11,12,13,14,15,16,17,18]. Therefore, this research defines a biowall as a living wall consisting of certain plants with specific substrates in a container assembled on a vertical wall [19] in the interior of a landed housing.…”

A biowall has the potential to provide human health and well-being benefits. However, some users consider a biowall as a hobby for their happiness. For this study, the general public's preference for a biowall was explored. The assessment was based on five criteria, perceptual, thermal, visual, respiratory, and audial comfort. The method assessed public preferences regarding the biowall in virtual reality for living and family rooms in urban dwellings. Six biowall configurations were virtualized in both rooms. These configurations included control conditions without biowall, single potting biowall, hidden single potting biowall, multiple potting biowall, linear potting biowall, and fully potting biowall. One-way ANOVA with Tukey HSD analyzed the data with the main result that the variants of the public's preferences for the biowall configuration were significantly different. The final result showed that the fully potting biowall was the highest rating configuration, with a preference value of 4.64 (N = 25) for the family room and 4.81 (N = 25) for the living room. The variables with the highest preferences for perceptual, thermal, visual, respiratory, and audial comfort were interest, chillness, color, freshness, and spaciousness-magnificence, respectively. The most dominant variable influencing preference was the ability of biowall to provide freshness and magnificence in the room. Generally, the public preferred the addition of biowall in the room.

“…Researchers also use reflection coefficient, transmission coefficient, and sound reduction index to evaluate the acoustic performance of green walls. Attal et al 57 employed the three microphones two-load method developed by Salissou et al 58 to experimentally characterize components of green wall structures and evaluated the corresponding reflection and transmission coefficients. The simulation results demonstrated that the presence of the foliage layer superimposed to the substrate layer does not affect the transmission loss but increases the return loss of the green wall structure.…”

Green wall technology, including green façades and living walls, presents a promising solution to encounter the negative impacts of noise pollution. Research and development of green walls are steadily progressing in multiple fields, including but not limited to the environmental, social, and economic areas. Compared to other themes, the number of acoustic studies of green walls is relatively low and lacks relevant review papers. The purpose of this paper is to give a systematic review of the application of green walls in the acoustic field and clarify the key factors that influence the acoustic performance of green walls and the main obstacles that obstruct the broader application of green walls. A total number of 34 papers published in the past 10 years are reviewed. This study identifies that the acoustic applications of green walls are mainly in four aspects, namely laboratory applications, outdoor applications, indoor applications, and audio-visual applications. Vegetation morphology and properties of substrates are the two crucial factors determining green facades and living walls’ acoustic properties, respectively. High installation, operation, and maintenance costs and plant-induced problems are recognized as the main obstructions. A few possible topics are recommended for future study as well.

“…Numerical simulations were also conducted to evaluate how propagation of traffic noise was affected by building enveloppe greening for different urban configurations [7,8]. Laboratory experiments have shown that the main contribution of this absorption comes from the substrate with a clear dependence to substrate composition [5,9,10,11], geometry [5,11,12,13] and moisture content [5,9,12].…”
