“…Perini et al [4] explains that living wall systems offer more creative potential-thus, improved aesthetical appeal-than green walls, as the variety of climbing plants that could be used on living walls is greater. The visual effect mostly depends on the plant density used for the wall coverage.…”

“…Green roofs, green facades, and living walls are sustainable building design elements that are steadily gaining in importance and being increasingly widely applied [1][2][3]. The application of green roofs is a much-established practice throughout the world [4]. On the other hand, the full potential of vertical greenery systems (VGS)-green facades and living walls-is not fully exploited.…”

The green facades and living walls of vertical greenery systems (VGS) are gaining increasing importance as sustainable building design elements because they can improve the environmental impact of a building. The field could benefit from a comprehensive mapping out of VGS types, an improved classification and nomenclature system, and from linking the benefits to a specific construction type. Therefore, this research reviews existing VGS construction types and links associated benefits to them, clearly differentiating empirical from descriptive supporting data. The study adopted a scoping research review used for mapping a specific research field. A systematic literature review based on keywords identified 13 VGS construction types—four types of green facades, nine types of living walls, and ten benefits. Thermal performance, as a benefit of VGS, is the most broadly empirically explored benefit. Yet, further qualitative studies, including human perception of thermal comfort are needed. Improvements in air quality, reduction of noise, positive effects on hydrology, and visual benefits need much further empirical testing, as the current supporting data is mostly descriptive and based on the similarities with green roofs. The educational benefits of VGS has no supporting empirical evidence, while the social benefits have only been empirically evaluated through one identified study. Future progress of the field depends on the adoption of a clear VGS nomenclature system and further qualitative and quantitative empirical testing of VGS benefits, which should be clearly linked to a specific VGS construction type so that cross-comparison of studies is enabled.

“…Understanding the interactions between microorganisms and cementitious materials is crucial and constitutes a fundamental step towards more durable, safer and higher quality structures in many contexts [30,[48][49][50]. However, as mentioned, the material's bioreceptivity (ability to be colonized by living organisms) is determined by the nature and the physico-chemical properties of the surface [48,51]: the chemical composition [52][53][54][55], roughness [56,57], porosity [57][58][59], hydrophobicity [53,[60][61][62], and pH [57,63].…”

Civil engineers have a responsibility to take measures to protect marine biodiversity by selecting more bioreceptive construction materials in the design of marine infrastructure, for better biodiversity conservation. In this study, it was shown that pre-carbonation of cementitious materials accelerates their bacterial colorization by lowering the pH of their surface. It has been shown both in the laboratory and in-situ tests that the bacterial colonization of cementitious materials is influenced by the pH and the type of cement. By comparing the bacterial colonization of Portland cement mortars, CEM I, and slag cement, CEM III, mortars, it was found that the CEM III mortars are more bioreceptive than the CEM I mortars. This study presented and verified a novel experimental laboratory approach which can be used to evaluate the bacterial colonization (bioreceptivity) of cementitious materials in marine environment. The approach could be taken up in future recommendations to enable engineers to eco-design more eco-friendly marine infrastructure and develop green-engineering projects.

Purpose The use of green wall technology in green buildings is a growing trend; however, more research is required about their maintainability, taking into account that maintainability at the design stage is a valuable strategy in achieving building efficiency and sustainability. Thus, the purpose of this paper is to determine the issues in operating and maintaining green walls, particularly in tropical areas like Singapore, leading to the development of a green maintainability framework. Design/methodology/approach This research uses a qualitative method that combines a thorough and systematic literature review, multiple case studies, field observation surveys and selected instrumental case studies with building plan appraisal and interviews to investigate the potential issues associated with the maintainability of green walls in tropical areas like Singapore. Findings The findings show that technical and environmental issues/defects are prevalent in the operation and maintainability of green wall technologies applied in green buildings located in tropical regions. Proper considerations of these findings will encourage green building designers and facilities managers to collaborate in the effective implementation of operations and maintenance of green building technologies. Originality/value This research gives new and significant information while identifying a clear knowledge gap. The paper recommends the formulation of a green maintainability framework with a set of design criteria that will serve as a benchmark in the future design of green walls. The green maintainability framework would be a valuable addition to green facilities management in ensuring the long-term maintainability and sustainability of existing and new green walls in tropical areas specifically in Singapore.
