“…Descriptive studies about VGS benefits could be found, but the benefits in those studies were simply described, and not measured or empirically tested [13,14,26,27]. A smaller number of studies contained specific measurements for an analyzed benefit [28][29][30].…”

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.

On the building of the BME-Odooproject, which participated in the Solar Decathlon competition in 2012, we were able to perform on-site impact measurements with deciduous (Parthenocissus quinquefolia, Parthenocissus tricuspidata) and evergreen (Hedera helix) plant-shading systems. The analysis of the bio-shaders' mechanism of action and data obtained during the research, proved that bio-shaders comply with the most important criteria of shading systems (to allow through the least energy ratio, reflect the largest share possible, minimise absorption and transmit the absorbed amount outward). This is due to the plant's structure, physiological processes, evaporation, and air movement. The bio-shadings meet and in certain cases, approach or even exceed these requirements; their efficiency is comparable to industrial blinds. As well as being a new form of architectural element, they also have many other ecological benefits; bio-shaders can play an important role in the building's energy balance, particularly in reducing the summer heat load.

“…This is due to the urbanization process where more impervious surfaces are found than grass or green area [1], which allows more heat from the solar radiation being absorbed by these hard surfaces, then reradiated and further heated-up the ambient temperature. Tropical regions where the sun is constantly high in the sky are experiencing intense solar radiation throughout the year.…”

Most developing countries lay close to the equatorial line of tropical climates with their cities experiencing rapid urbanization, population growth and physical change. This accelerates the changes in their urban landscape, which results in, among others things, the urban heat island phenomenon (UHI). The global temperature increment also increases the cooling load and thus more energy is consumed. Attention is given to building design and its technological advancement in energy saving and conservation; not much research is being conducted on the Malaysia's microclimate and the outdoor thermal environment, although they affect the energy consumption of buildings. This paper discusses the approaches adopted in investigating the hot-humid outdoor environment of Malaysia towards understanding how landscape design is affecting the microclimate. Several cases of past research on how ground surfaces affect the adjacent thermal environment, the impact of landscape setting on the microclimate and the influence of the physical dimensions of trees in screening solar radiation are presented. These parameters seem to have a direct influence on the outdoor thermal performance. The findings suggested that the landscape settings influence the microclimate of outdoor spaces, where the high quantity of trees and large tree size seems to lower the ambient temperature. Turfed surfaces seem to lower the ambient temperature compared to tar-mac surfaces. Several recommendations through design initiatives to mitigate the UHI effects in urban areas are made.
