Abstract

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.

Abstract

Purpose

The UN forecast of a 3-degree Celsius global temperature increase by 2,100 will exacerbate excessive heat. Population growth, urban densification, climate change and global warming contribute to heat waves, which are more intense in high-density environments. With urbanisation, vegetation is replaced by impervious materials which contribute to the urban heat island effect. Concurrently, adverse health outcomes and heat- related deaths are increasing, and heat stress affects labour productivity. More green infrastructure, such as green walls, is needed to mitigate these effects; however maintenance costs, OH&S issues and perceptions of fire risk inhibit take up. What if these barriers could be overcome by a green Wallbot? This research examines the feasibility of integrating smart technology in the form of a Wallbot.

Design/methodology/approach

The research design comprised two workshops with key stakeholders; comprising green wall designers and installers, green wall maintenance teams, project managers and building owners with green wall installations, horticulture scientists, designers and mechatronics engineers. The aim was to gain a deeper understanding of the issues affecting maintenance of green walls on different building types in New South Wales Australia to inform the design of a prototype robot to maintain green walls.

Findings

The Wallbot has great potential to overcome the perceived barriers associated with maintaining green walls and also fire risk and detection. If these barriers are addressed, other locations, such as the sides of motorways or rail corridors, could be used for more green wall installations thereby increasing mitigation of UHI. This innovation would be a welcome addition to smart building technology and property maintenance.

Research limitations/implications

This is a pilot study, and the sample of stakeholders attending the workshops was small, though experienced. The range of green walls is varied, and it was decided to focus initially on a specific type of green wall design for the prototype Wallbot. Therefore other types and sizes of green walls may suit other specifications of Wallbot design.

Practical implications

To date, no robot exists that maintains green walls, and this innovative research developed a prototype for trialling maintenance and inspection.

Originality/value

To date, no robot exists that maintains green walls. No study to date has assessed stakeholder perceptions and developed prototype Wallbot technology.

Abstract

Purpose

The purpose of this paper is to identify green envelope building components of residential buildings applicable under hot and humid climates and to analyze the effect of these components on building value.

Design/methodology/approach

The authors place an emphasis on green envelope components that influence building value and which are derived based on their integration into a building envelope structure that is applicable under hot and humid climates. This is performed through identification of green benefits of each green envelope component based on literature reviews and in relation to green criteria listed by the Malaysia Green Building Index (GBI). Consequently, a quantitative analysis has been conducted to determine the effect of these green envelope components on building value by means of a questionnaire distribution among 550 property valuation practitioners in Malaysia. However, in order to certify respondents’ credibility, the authors analyzed questionnaires answered by property valuation practitioners with experience in green valuation.

Findings

The findings show that there are ten green envelope components currently certified under GBI Malaysia and applicable for hot and humid climates. There are three green envelope components that can increase property values, specifically: solar photovoltaic, green living wall and green roof. However, eight of the green envelope components have no effect on building value.

Research limitations/implications

Due to the relative immaturity of the green building market in Malaysia, the authors were unable to analyze the actual percentage of increment on building value as conveyed by each green envelope component.

Originality/value

This paper aims to provide understanding of the effect of individual green envelope components on building value rather than merely the value of green buildings in general. It proves that green building envelope components do in fact contribute to an increase in green building values. As the green building market in Malaysia is still in its infancy, this study is significant in that it prepares the Malaysian green building market to attain a new level by providing valuation practitioners with awareness of green building values and new knowledge concerning the effect of individual green components on building values. Hence, it is anticipated that this study can assist property valuation practitioners in conducting valuations of green buildings in the future.

Abstract

Nature-based solutions (NBS) generate different impacts at the urban scale, such as the ability to regulate water or store carbon, comparable to traditional, gray infrastructures in a more cost-efficient way. On the other hand, by their intrinsic nature, NBS do deliver a series of other services that are commonly defined as social, economic, and environmental cobenefits. These benefits are not always valued in a consistent and complete way, so there is the need to compile a more comprehensive evidence base on the social, economic, and environmental effectiveness of NBS. The chapter attempts to identify a categorization of the existing NBS and define the ecosystem services (ES) provided by them. Furthermore, starting from the results achieved through the definition of the existing NBS frameworks assessment, the chapter will identify a set of key performance indicators KPIs, based on the ES produced by NBS, to measure the economic, social, and environmental benefits generated in by NBS at the urban level taking into account their multifunctional character. In total, 66 key performance indicators have been individuated: 3 for provisioning services, 38 for regulating services, 17 for cultural services, and 8 for supporting services. Each indicator has been associated to a category of ES in order to measure and evaluate the performances of NBS implemented in cities.

Abstract

Purpose

Green walls (GWs), comprising living walls and green facades, have been touted as environmentally friendly products in architectural design. GWs can be viable in every aspect of sustainability; they provide residents of buildings with a wide range of economic, social and environmental benefits. Despite this, the adoption rate of GW is still in its infancy stage, and the existing literature concerning the hindrances inhibiting GW adoption is very limited. To address these gaps, the aim of this paper is to identify and prioritize the hindrances to GW adoption in Hong Kong.

Design/methodology/approach

After identifying 17 hindrances through an in-depth review of literature, the fuzzy Delphi method (FDM) is employed to refine the hindrances based on the local context with the help of 21 qualified experts in the field. Subsequently, Fuzzy Parsimonious Analytic Hierarchy Process (FPAHP) is exploited as a recently developed technique to prioritize the identified hindrances.

Findings

Results reveal that the most significant hindrances to the adoption of GW are maintenance cost, high installation cost, difficulties in maintenance, sophisticated implementation and inducement to fire. Findings call for scholars to address ways to improve GW installation practices and methods in order to eradicate the hindrances and provide lessons for policymakers, assisting them in facilitating the larger-scale adoption of GW.

Originality/value

Considering the dearth of studies on hindrances to the adoption of GWs, this paper provides a comprehensive outlook of the issue, providing knowledge that can be used as a building block for future scholars within the field. It also provides valuable insights for stakeholders within the construction industry about the hindrances to the adoption of GWs which could direct their efforts toward better implementation of it.

Abstract

Numerous researchers proved Vertical Greenery System VGS beneficial to buildings and surroundings. However, it is still not widely applied in the tropics like Malaysia. This paper aims to determine the perceptions of VGS among the end users before it can be improved. A survey was conducted among 40 respondents, the end users of VGS in selected buildings within Klang Valley area. The collected data was analysed using statistical tests. From the findings, the primary benefits of VGS perceived by end users are enhancing visual quality, bringing nature harmony, reducing stress and reducing the urban heat island effects. The perceptions contradict with the results of ANOVA test between reducing the urban heat island effects and other VGS benefits that proves the need and effort to work on VGS in Malaysia.

Abstract

With the accelerating process of urbanization, the greening areas in high density cities are becoming less and less, and the aerial greening provides a possible way for the update of the urban building headspace greening. Based on this, the application of aerial greening in the urban headspace was studied. Starting from the plant, water, landscape sketch, pavement and other construction elements, the ecological art planning and design of the urban building headspace was studied. Then, the transformation of an old factory was studied, and the rain-flood gardens and infiltration floors linked to biological corridors were introduced in the high flood risk areas. In the building headspace, a rainwater harvesting system and an air garden were designed, and the ecological planning of aerial walkway was carried out to the front abandoned viaduct. The practice proves that the introduction of ecological science and technology and art culture in the urban headspace plays an important role in purifying urban air and increasing urban greening.

Abstract

Purpose

The study aims to develop recommendations for optimal Internet of things (IoT) based solutions for a smart precision irrigation automation platform using morphological thinking (MT). The smart irrigation system (SIS) can be applied for green roof and green wall (GRGW) design by studying the relationships and configurations that will be analyzed, listed and synthesized, representing “solutions spaces” and their possibilities.

Design/methodology/approach

The research examines studying various cases of SIS; and assessing and analyzing the identified case studies through a decision support system (DSS) considering several factors regarding IoT, plant characteristics, monitoring, irrigation system and schedule, climate, cost and sensors used.

Findings

To develop recommendations for optimal IoT-based solutions for a smart precision irrigation automation platform.

Originality/value

The research paper analyzes and proposes a simultaneous solution to two conflicting problems. On the one hand, the paper proposes to apply greening of walls and roofs in hot arid regions, which will achieve greater environmental comfort. However, this is extremely difficult to implement in hot arid regions, since there is an objective problem – a lack of water. At the same time, the paper proposes the most rational approaches to organizing an irrigation system with the lowest water consumption and the highest efficiency for landscaping. Accordingly, this paper focuses on evaluating different types of SIS about the hot-arid climate in Qatar. The study aims to develop recommendations for optimal IoT-based solutions for a smart precision irrigation automation platform, which can be applied for green wall and roof design.

Abstract

Purpose

The purpose of this study is to explore the perceptions of built environment professionals on the benefits and impediments limiting the widespread acceptance of vertical greening systems (VGSs) in Lagos, Nigeria. This study contributes to the knowledge on the adoption of VGSs from the socio-technical dimension.

Design/methodology/approach

The study employed a survey method. An online questionnaire was used to obtain information from the respondents. The questionnaire was divided into four (4) sections. The first section focused on the socio-demographic variables while the second section addressed knowledge of VGSs, willingness to educate clients on the use of VGS and the possibility of VGS improving city image in Lagos. Section three (3) focused on the VGS benefits, subdivided into environmental, economic and aesthetic qualities and measured on a five-point Likert scale. Lastly, section four (4) concentrated on the impediments to the use of VGS in Lagos.

Findings

Professionals are willing to adopt the use of VGSs if their clients agree to the benefits it delivers to occupants, the environment and the building fabric.

Originality/value

This paper fulfills an identified need to study the perceptions of professionals toward VGSs patronage.

Abstract

Sustainability issues have become crucial to mitigate urban heat islands (UHIs) and reduce the global warming effect. The climate change news is frequently heard lately due to the extreme weather to the extent that the increasing earth’s temperature often causes disaster and loss of property and life. New adaptation needs to new climate context and limits the on-going effects. One of the ways is adopting green roofs on buildings. Implementing sustainable practices such as green roofs will help mitigate this adverse effect in urban areas. Green roofs provide many benefits such as enhancing the aesthetical quality of the built environment, reduce UHIs, reduce energy consumption, improve storm-water attenuation, roof longevity, and reduce noise pollution. However, only a few buildings in Malaysia have considering green roofs as a main green feature element. There is barely number of buildings that have green roof design even though it offers benefits to the community and environment. This chapter has emphasised the types of green roof systems that are potentially suitable in Malaysia climate and obstacles associated with the green roof system. The study found the barriers to implementing green roofs in Malaysia, especially during the stage of building operation in maintaining the green roof system. The survey has been done, which revealed nine factors that hinder the green roof application. This study also highlights the challenges to overcome the barriers of implementing green roofs in Malaysia.
