“…Research on the preservation and construction of natural capital in Korea was conducted for green growth evaluation techniques [ 36 , 37 ], urban planning and GIS utilization planning techniques [ 38 , 39 ], and volume mapping research on vegetation sites [ 40 ]. In addition, studies were conducted to cope with climate change, focusing on topics such as the impact and utilization of green infrastructure on climate change [ 41 , 42 , 43 ], greenhouse gas reduction and thermal environment improvement [ 44 , 45 , 46 , 47 ], and air quality management such as fine dust reduction [ 48 , 49 , 50 ].…”

Government-level ESG (environmental, social, and governance) institutionalization and active ESG activation in the private sector are being discussed for the first time this year in Korea, spurred by increased national interest since the COVID-19 pandemic crisis and the declaration of a carbon-neutral society by 2050, and ESG discussion in many fields is spreading rapidly. In addition, global awareness of the crisis caused by environmental pollution and natural disasters has highlighted the importance of green infrastructure (GI) as a new conceptual alternative to improve public value. Based on sustainability, which is a common goal of ESG and green infrastructure, this study aimed to examine the research targets and techniques of green infrastructure from the perspective of ESG. This study selected and analyzed 98 domestic and international academic journal papers published over the past 10 years in the Web of Science academic journal database literature collection. Focusing on the research subjects, the focus on green infrastructure, and research keywords, we examined the aspects of the green infrastructure plan that have been focused on from the ESG perspective and compared domestic and international research trends. In addition, implications for how each research topic is connected to the concept of ESG according to its function and purpose were derived. By examining the domestic and international research trends of green infrastructure from the ESG perspective, we identified the need for a wider range of research on the diversity and relationship between humans and the ecological environment; policies and systems; and technical research that does not focus only on a specific field. In this regard, we intend to increase the contribution to ESG management in the public sector through the establishment of green infrastructure plans and policies in the future, as they account for a large portion of public capital.

“…To determine basic data on the effectiveness of façade greening, model and wind tunnel studies [35,36] are used in addition to field studies, as well as, for example, climatic chamber studies. These studies benefit from the advantage of controlling influencing factors [37], such as wind speed, temperature, and humidity, in larger or smaller parts. This is also demonstrated in the field study of Viecco et al [38], where tests are performed under controlled environmental conditions in a room, followed by gravimetric procedures to measure particle concentration [39].…”

“…This result, in turn, indicates the importance of the external influencing factors and the use of uniform measurement methods. To identify differences between plant species, the same environmental conditions would need to be produced [37]. An extension of the already investigated parameters should include the air pollution tolerance index (APTI) in future measurements.…”

Particulate matter (PM) exposure in urban areas is a continuous threat to human health and requires sustainable solutions for effective reduction. The aim of this study is to provide a comprehensive overview of façade greening and its effects on PM and to identify knowledge gaps. We systematically screened, analyzed, and re-evaluated previous reviews according to the criteria established for an umbrella review. As a result, this study covers and discusses common measurement methods, influencing factors, the effectiveness of façade greening, leaf characteristics, and plant species from different subtopics. The main findings are that inconsistent measurement methods limit the comparability of the analyzed reviews, and different climatic conditions affecting the use of plant species lead to different international effects. Despite the existing studies reporting a positive effect on the reduction of PM, comparability is difficult due to methodological differences and external influences. Given the complexity, interdisciplinary collaboration with experts is essential to increase the effectiveness of façade greening for PM accumulation for healthy urban air. We suggest that this umbrella review provides a foundation for future research and practical implementations, such as a suitable plant selection or façade design, by integrating the results.

“…VGSs offer many simultaneous benefits, including the fact that they have a positive impact on climate-change-related challenges and contribute to its mitigation and adaptation: e.g., they contribute to carbon sequestration [6,7] by absorbing carbon dioxide (CO 2 ) from the atmosphere and helping to locally reduce the concentration of greenhouse gases at a macroscale level. In addition, VGSs help to improve air quality by filtering pollutants and particulate matter from the atmosphere [8,9] because plants can absorb harmful gases and toxins, thus reducing their concentration in the urban environment and improving the overall air quality for residents. Finally, VGSs enhance urban biodiversity by providing habitats for various plant species and animals [10].…”

Urban heat island (UHI) mitigation and adaptation are urgent needs in a built environment, which requires us to search for sustainable solutions to limit the urban heat island effect and improve the energy efficiency of building envelopes. Among these solutions, vertical green structures (VGSs) have recently attracted significant attention for their potential to mitigate adverse effects, especially in densely built areas. This study presents a comprehensive data analysis of the microclimate of a living wall in Milan, Italy. Our aim was to evaluate this VGS’s performance in mitigating temperature increases caused by the UHI effect. In the literature, similar studies are limited to shorter monitoring periods (mostly in cooling seasons) and specific orientations (mostly facing south). However, the VGS presented in this case study here faces northwest and was continuously monitored for one calendar year. During this continuous in situ monitoring campaign, air temperature data from sensors either embedded in vegetation or exposed on a bare wall were collected and analysed over a whole calendar year, which is a novelty compared to the existing literature focused on VGSs due to the long duration. The findings indicate that the studied VGS has the ability to influence the outdoor microclimate depending on the season, the precipitation events, the wall exposure, the type of vegetation, and the vegetation’s phenological attributes. The analysis showed that the VGS consistently maintained cooler temperatures than the bare wall, with mean temperature differences ranging from 2.8 °C in autumn to 0.8 °C in spring through the winter. The vegetation acted as a natural insulator by reducing the air temperature during the hot summer and in early autumn, corresponding to the growing period of the vegetation. Thus, VGSs show potential to mitigate the global warming effect. These findings provide valuable insights on vegetation’s capability to act as a thermal regulator for sustainable urban planning and energy-efficient building design and retrofitting.
