In the challenge of development in dense urban areas and environmental preservation, sustainability is a significant requirement where green facade (vertical greening) is one of those approaches that flourished during the last decade although it is not a new concept. Hanging or vertical garden, vertical vegetable farms, balcony garden, container or planter box greening, green or eco building, green roof or rooftop garden, wall planter, and green envelop are all different aspects of this idea that demonstrate how wide this landscape can be. Greening the building envelope with vegetation can be used as a mean to restore the environmental conditions in dense urban areas. Designers can look for enhanced solutions where the façades are more than tinted glass barrier. Several researches have proven the environmental benefits of green facade on both new and existing buildings. They can be applied for mitigating the effect of urban heat island, increasing biodiversity and ecological value, insulating against environmental impact, outdoor and indoor comfort, social and psychological wellbeing and enhancement of air quality for city dwellers. This article discusses different systems of the green facade as a method of sustainable development.

To overcome the excessive heat in tropical climate countries during the day, the types of skin or façade play a vital role in regulating the temperature and the amount of heat transmission in a building. This research was carried out to evaluate the percentage of temperature reduction of two building samples, one with “vertical greening” and one without. The result proved that the temperature reduction of the building with the green façade system is higher than the building without the green façade system. Therefore, it justifies that Vertical Greening Wall does act as an acceptable passive approach for sustainable design.2398-4279 © 2016. The Authors.

Sustainable development demands a significant approach between architecture and the environment. During the challenge of climate change, energy crisis and urban expansion, a new approach is required to address environmental problems and one of these approaches is vertical greening that can be categorized into green facade and living wall.Living wall systems (LWS) consist of plants and partly growing materials that have a number of beneficial functions, for example: increasing the outdoor and indoor comfort, ecological value, biodiversity, insulation properties, improvement of air quality mitigation of the urban heat island phenomenon, and psychological and social well-being of citizens. This paper focuses on different types of living wall systems as a method of sustainable development and their opportunities and threats were discussed.

This project is part of research series to observe the thermal characteristic of green facade to minimize the cooling load inside building. The aim is to analyze the building thermal characteristic on the green facade installed on a building model. Various kinds of leaves covered area (experiment I: 0%, experiment II: 50%, and experiment III: 90%) were used as the main parameter. Calculation in decrement factor and time lag were also done in order to support the analysis of heat flows calculations. Data measurement showed that ambient and facade surface of green facade with the greatest leaves covered area (experiment III) had lower temperature profiles. Data calculation also showed the highest of average heat flows were found out in the bare wall model. Results for heat flow in the wall surface were 4.69 W/m2 (experiment I), 3.88 W/m2 (experiment II), and 1.61 W/m2 (experiment III). While for heat flows through indoor air space, they were 27.75 W/m2 (experiment I), −5.10 W/m2 (experiment II), and 8.99 W/m2 (experiment III). As shown from data analysis, the quantities of leaves covered area effected the cooling down on the building envelope by reducing the quantity of heat flows from exterior to interior side.

There is increasing interest in developing urban design principles that incorporate good ecological management. Research on understanding the distribution and role of beneficial pollinating insects, in particular, is changing our view of the ecological value of cities. With the rapid expansion of the built environment comes a need to understand how insects may be affected in extensive urban areas. We therefore investigated insect pollinator capture rates in a rapidly growing and densely urbanized city (Melbourne, Australia). We identified a remnant native habitat contained within the expansive urban boundary, and established study sites at two nearby populated urban areas. We employed standard pan trap sampling techniques to passively sample insect orders in the different environments. Our results show that, even though the types of taxonomic groups of insects captured are comparable between locations, important pollinators like bees and hoverflies were more frequently captured in the remnant native habitat. By contrast, beetles (Coleoptera) and butterflies/moths (Lepidoptera) were more frequently observed in the urban residential regions. Our results suggest that the maintenance of native habitat zones within cities is likely to be valuable for the conservation of bees and the ecosystem services they provide.

Abstract - Using vertical greenery systems to reduce heat transmission is becoming more common in modern architecture. Vertical greenery systems are divided into two main categories; green facades and living walls. This study aims to examine the thermal performance of vertical greenery systems in hot and humid climates. An experimental procedure was used to measure indoor temperature and humidity. These parameters were also measured for the gap between the vertical greenery systems and wall surfaces. Three boxes were used as small-scale rooms. Two boxes were provided with either a living wall or a green facade and one box did not have any greenery (benchmark). Blue Trumpet Vine was used in the vertical greenery systems. The data were recorded over the course of three sunny days in April 2013. An analyses of the results showed that the living wall and green facade reduced indoor temperature up to 4.0 °C and 3.0 °C, respectively. The living wall and green facade also reduced cavity temperatures by 8.0 °C and 6.5 °C, respectively.

Vertical Greening

Urban greening provides a wide range of ecosystem services to address the main challenges of urban areas, e.g., carbon sequestration, evapotranspiration and shade, thermal insulation, and pollution control. This study evaluates the environmental sustainability of a vertical greening system (VGS) built in 2014 in Italy, for which extensive monitoring activities were implemented. The life-cycle assessment methodology was applied to quantify the water–energy–climate nexus of the VGS for 1 m2 of the building’s wall surface. Six different scenarios were modelled according to three different end-of-life scenarios and two different useful lifetime scenarios (10 and 25 years). The environmental impact of global-warming potential and generated energy consumption during the use phase in the VGS scenarios were reduced by 56% in relation to the baseline scenario (wall without VGS), and showed improved environmental performance throughout the complete life cycle. However, the water-scarcity index (WSI) of the VGS scenarios increased by 42%. This study confirms that the installation of VGSs offers a relevant environmental benefit in terms of greenhouse-gas emissions and energy consumption; however, increased water consumption in the use phase may limit the large-scale application of VGSs.

The Impact

Permeable surfaces for roads and footpaths have been used as a means of disposal of stormwater in developed urban areas. Such surfaces provide an alternative to impermeable concrete or tarmacadam surfaces which would otherwise produce rapid stormwater runoff, leading to possible flooding and degeneration of receiving water quality through the uncontrolled discharge of polluted urban waters. A further advantage may be obtained from such constructions by undersealing them so as to retain stormwater for re-use for non-potable uses. The potential for general introduction of this type of storage and re-use system in residential areas is discussed and possible alternative designs for the drainage infrastructure proposed. To have widespread impact such a strategy must deliver cost savings as well as reduce the impact on the water environment of anticipated water usage demands. The source of such cost savings and the general environmental benefits of such systems will be presented. The materials used in such a sealed construction and the beneficial changes to the stored water quality are outlined. Recent work has also shown that where the pavement is used for car parking any oils dropped on the surface and washed into the structure by the stormwater may also be degraded. Details will be given of a site in the UK where the above construction is to be used to provide stormwater storage for re-use in flushing toilets at a Youth Hostel.
