“…For example, plant transpiration increases indoor relative humidity by 9-12% [10]. This may be favorable for indoor comfort in arid regions but could be disadvantageous in hot and humid regions [15]. Other considerations include the noise made by hydroponic systems [16], a minor chance of discomfort as a result of allergies [17], and energy consumption and heat dissipation caused by the artificial growth lights [18].…”

Vertical farming is a new branch of urban agriculture using indoor vertical space and soil-less cultivation technology to obtain agricultural products. Despite its many advantages over traditional farming, it still faces some challenges and obstacles, including high energy consumption and costs, as well as uncertainty and a lack of social acceptance. This study aims to investigate the influence of public acceptance on micro-vertical farming based on the deconstructed theory of planned behavior model. This model is adopted for statistical analysis to reveal the factors and their weights in influencing people’s behavioral intentions. The results indicate that the overall mean of the public’s behavioral intentions to use vertical farming is 3.9, which is above neutral (M = 3.00) but less than positive (M = 4.00). Differences in age, education level, and the living area of the public have significantly impacted behavioral intentions. Meanwhile, the statistical results support the hypotheses concerning the behavioral attitudes, subjective norms, and perceived behavioral control of the model, and also demonstrate that their decomposed belief structures considerably influence the public’s behavioral intentions to use vertical farming. Notably, perceived usefulness is the most critical driving factor in planting using vertical farming. The findings of this study contribute to better predictions of the effects of different elements of behavioral intention on vertical farming at the urban scale, which may provide a basis for decision making in the development of sustainable urban agriculture.

“…When only 2.5 modules were added, the improvement in increasing the chamber humidity level was only 76.92 %. This relative humidity elevation was directly proportional to the analysis of Shao et al in offices of 3.1-6.4 % (Shao et al, 2021b).…”

<p>Biowalls are a new phenomenon in interior urban areas, which has proven to contribute positively to sensory comfort. But people use biowalls in different dimensions. Based on field facts, determining the biowall dimensions for human sensory comfort has not emphasized clear principles. The research aims to obtain the effective area of a biowall inducing sensory comfort comprehensively and simultaneously in tropical landed dwellings. Therefore, this study used the experimental method to extract the effective areas of the biowall to generate thermal, audial, visual, and respiratory comfort. The analysis was mathematically conducted through polynomial quadratic equations and directly or inversely proportional to the overall value regarding a generalization attempt. The variables measured included temperature, humidity, surface temperature, reverberation time, noise reduction, illuminance, luminance, and colour mapping, as well as levels of CO2, TVOC, HCHO, and PM2.5. The result showed that biowall effective area inducing thermal, audial, visual, and respiratory comfort for a (3000 x 3000 x 2500) mm3 room was 2.5 modules or 12.5 m2 leaf area. This value was able to provide an increase in the sensory comfort level for the thermal, audial, visual, and respiratory variables by 59.22 %, 76.64 %, 32.35 %, and 98.88 %, respectively.</p>

“…The results are consistent with the results obtained in several investigations, where the effect of installing green walls on IAQ was studied. Tudiwer & Korjenic [7], found a decrease in CO 2 in a study carried out in a school building in Vienna, Austria; Peterková et al [8] also observed a decrease in CO 2 concentrations in a classroom at the Faculty of Civil Engineering at the Technical University of Brno, Czech Republic; Pettit et al [9], in a school in Beijing, observed a decrease in VOCs concentrations; and Shao et al [10], at a university in China, observed a reduction in CO 2 and PM 2.5 levels after installing a green structure in a small corridor.…”

According to the World Health Organization, good air quality is a basic requirement for life, being a determining factor for the health and well-being of occupants in indoor spaces. In schools, and due to the complex and diversified activities carried out, indoor air quality (IAQ) can also have a direct impact on student performance and well-being. Good indoor air quality can be ensured, among other measures, using plants capable of absorbing indoor contaminants. In addition to improving indoor air quality, plants also have numerous benefits in terms of occupant performance and wellbeing.The present study aimed to analyze the impact of the installation of a natural green structure (NGS) on the indoor air quality of a classroom at the Instituto Superior de Engenharia de Lisboa, through the monitoring of several chemical and physical parameters, namely volatiles organic compounds (VOC´s), carbon dioxide (CO2), carbon monoxide (CO), particulate matter suspended in the air (PM10 and PM2.5), temperature (T) and relative humidity (RH). It was also evaluated the well-being of students, through the application of online questionnaires. The results of the specific IAQ measurements allowed to verify that, despite the existence of some non-compliance, the indoor air quality of the classrooms is, in general, acceptable and, after the installation of the NGS, there was a slight decrease in the VOC´s, CO2 and PM2.5 concentrations, which seems to suggest a slight but positive influence of the plants on the IAQ in the classroom. On the other hand, the results of the applied questionnaires, allowed to verify a positive effect of the NGS in the students' perception in relation to the classroom, in the reduction of the anxiety levels and in the decrease of the negative feelings.
