  • Stakeholder relationships in off-site construction: a systematic
           literature review
    • Authors: Bao Ngoc Nguyen, Kerry London, Peng Zhang
      Abstract: This paper aims to report a comprehensive analysis of literature on stakeholder relationships towards identifying patterns of relationships within the off-site construction context. Key scholarly databases were accessed and after a filtering process, 74 relevant papers were retrieved for analysis. The papers were analysed using qualitative content analysis and scientometric techniques through the application of software Leximancer and VOSviewer. Research synthesis methods used in the present study generate compatible results. Through text mining analysis, the key themes identified in the off-site construction stakeholder relationships literature included “collaboration”, “building information modelling”, “social network analysis”, supply chain. As a finding by scientometric analysis, collaboration, BIM, supply chain management, housing and social network analysis were the most frequently entered keywords context of off-site construction. Regarding authorship pattern, the whole network of collaboration was fragmented into multiple isolated clusters, implying that the authors had tendency to cooperate in small groups. The paper can bring together an important area of research not previously studied in detail. It will primarily assist academics in the first instance; however, the research leads to important findings that will ultimately assist policymakers and practitioners better understand factors affecting stakeholder relationships and in particular network thinking and collaborative mind-sets. The review contributes a needed systematic and theoretical foundation for future stakeholder relationship studies and practices in off-site construction sector. It provides the basis for future studies and is a seminal analysis of stakeholder management and off-site construction. The scientometric methodology offers scholars a different approach to analysing and visualising literature reviews.

  • On the hybridization of pre-trained deep learning and differential
           evolution algorithms for semantic crack detection and recognition in
           ensemble of infrastructures
    • Authors: Eslam Mohammed Abdelkader
      Abstract: Cracks on surface are often identified as one of the early indications of damage and possible future catastrophic structural failure. Thus, detection of cracks is vital for the timely inspection, health diagnosis and maintenance of infrastructures. However, conventional visual inspection-based methods are criticized for being subjective, greatly affected by inspector's expertise, labor-intensive and time-consuming. This paper proposes a novel self-adaptive-based method for automated and semantic crack detection and recognition in various infrastructures using computer vision technologies. The developed method is envisioned on three main models that are structured to circumvent the shortcomings of visual inspection in detection of cracks in walls, pavement and deck. The first model deploys modified visual geometry group network (VGG19) for extraction of global contextual and local deep learning features in an attempt to alleviate the drawbacks of hand-crafted features. The second model is conceptualized on the integration of K-nearest neighbors (KNN) and differential evolution (DE) algorithm for the automated optimization of its structure. The third model is designated for validating the developed method through an extensive four layers of performance evaluation and statistical comparisons. It was observed that the developed method significantly outperformed other crack and detection models. For instance, the developed wall crack detection method accomplished overall accuracy, F-measure, Kappa coefficient, area under the curve, balanced accuracy, Matthew's correlation coefficient and Youden's index of 99.62%, 99.16%, 0.998, 0.998, 99.17%, 0.989 and 0.983, respectively. Literature review lacks an efficient method which can look at crack detection and recognition of an ensemble of infrastructures. Furthermore, there is absence of systematic and detailed comparisons between crack detection and recognition models.

  • Sustainable strategy to create multisector or unisector smart economic
           hubs
    • Authors: Mohammed Osama Rasmy, Tarek Abdel Latif Abu Atta, Asmaa Abdelaty Mohamed Ibrahim
      Abstract: This study explores the best strategies for regional economic development to attract highly skilled populations, regardless of whether the region is a multisector or unisector economic hub. It also determines the development variables affecting the success of integrated regional economic hubs to achieve spatial equality, enhance economic productivity and attain environmental sustainability. In addition to a qualitative analysis, this study employed quantitative techniques using SPSS software. This allowed amplification of the most significant explanatory variables affecting the weaknesses and strengths of economic hubs. The results highlight approaches that can be used to achieve socio-economic sustainability in regional hubs. These include multisectors or main centralised hubs (smart economic regional capital), which provide new services to regions and act as a unidevelopment sector or as a regional, economic capital. The study analyses the effect of economic strategies and integration of natural resources and the required core services in regional economic development. Case studies of successful economic hubs are discussed. The most important services proposed in such hubs promote human development and increase the standard of living. Integration between the hubs in a region is fundamental to attracting direct investments that can benefit the local population. The results could help governments, economists and planners implement multisector developmental hubs to achieve sustainable development.

  • An investigation on the impact of shading devices on energy consumption of
           commercial buildings in the contexts of subtropical climate
    • Authors: Md. Jewel Rana, Md. Rakibul Hasan, Md. Habibur Rahman Sobuz
      Abstract: Application of appropriate shading device strategies in buildings can reduce direct solar heat gain through windows as well as optimize cooling and artificial lighting load. This study investigates the impact of common shading devices such as overhangs, fins, horizontal blinds, vertical blinds and drapes on energy consumption of an office building and suggests energy efficient shading device strategies in the contexts of unique Bangladeshi subtropical monsoon climate. This research was performed through the energy simulation perspective of a prototype office building using a validated building energy simulation tool eQUEST. Around 100 simulation patterns were created considering various types of shading devices and building orientations. The simulation results were analysed comprehensively to find out energy-efficient shading device strategies. Optimum overhang and fin height is equal to half of the window height in the context of the subtropical climate of Bangladesh. South and West are the most vulnerable orientations, and application of shading devices on these two orientations shows the highest reduction of cooling load and the lowest increment of lighting load. An existing building was able to save approximately 7.05% annual energy consumption by applying the shading device strategies that were suggested by this study. The shading device strategies of this study can be incorporated into the Bangladesh National Building Code (BNBC) as new energy-efficient building design strategies because the BNBC does not have any codes or regulations regarding energy-efficient shading device. It can also be used as energy-efficient shading device strategies to other Southeast Asian countries with similar climatic contexts of Bangladesh.

  • A receptive-responsive tool for customizing occupant's thermal comfort and
           maximizing energy efficiency by blending BIM data with real-time
           information
    • Authors: Zeynep Birgonul
      Abstract: The heating, ventilation and air conditioning systems are responsible for a significant proportion of the energy consumption of the built environment, on which the occupant's pursuit of thermal comfort has a substantial impact. Regarding this concern, current software can assess and visualize the conditions. However; integration of existing technologies and real-time information could enhance the potential of the solution proposals. Therefore, the purpose of this research is to explore new possibilities of how to upgrade building information modeling (BIM) technology to be interactive; by using existing BIM data during the occupation phase. Moreover, the research discusses the potential of enhancing energy efficiency and comfort maximization together by using the existing BIM database and real-time information concomitantly. The platform is developed by designing and testing via prototyping method thanks to Internet of things technologies. The algorithm of the prototype uses real-time indoor thermal information and real-time weather information together with user's body temperature. Moreover, the platform processes the thermal values with specific material information from the existing BIM file. The final prototype is tested by a case study model. The outcome of the study, “Symbiotic Data Platform” is an occupant-operated tool, that has a hardware, software and unique Revit-Dynamo definition that implies to all BIM files. The paper explains the development of “Symbiotic Data Platform”, which presents an interactive phase for BIM, as creating a possibility to use the existing BIM database and real-time values during the occupation phase, which is operated by the occupants of the building; without requiring any prior knowledge upon any of the BIM software or IoT technology.

  • Barriers to sustainable construction project management: the case of Iran
    • Authors: Ali Fathalizadeh, M. Reza Hosseini, Seyyed Saeed Vaezzadeh, David J. Edwards, Igor Martek, Salman Shooshtarian
      Abstract: The barriers to integrating sustainable practices into construction project management require extensive resource allocations to resolve. Within developing countries such as Iran (where resources are scarce), remedial strategies adopted must prioritise tackling those barriers that can be expected to yield maximum return on investment. The candidate barriers are many, and this paper aims to identify a hierarchy of barriers, providing a priority list of remedial targets. A mixed philosophical stance of interpretivism and post-positivism is adopted within a deductive approach and survey strategy. A list of 30 known barriers are identified from extant literature and used to formulate a questionnaire data collection instrument administered within the Iranian construction industry. Data collected from 176 practitioners are analysed using the relative importance index and Mann–Whitney U test to compare groups based on the participants' demographic variables. The findings challenge the common assumption that items related to market and workforce experience are major inhibitors of change. That is, economics and regulatory dependent barriers have a higher impact on the failure of a shift to sustainable practices in Iran. The most influential barriers to incorporating sustainability in construction projects are: (1) lack of understanding of the potential benefits; (2) insufficient cooperation among practitioners, research institutions and environmental organisations; and (3) a lack of a systematic approach to pursuing sustainability goals. No significant associations are detected between the affiliation of the respondents and their attitude towards the issue. Thus, a generalised approach can be applied to a broader range of organisations and construction projects in Iran. While studies on sustainability impediments at the firm or project level are ubiquitous within literature, this research identifies that the most significant barriers to sustainable project management in Iran, as an underexplored context, are those experienced at the economic and institutional level. Moreover, this novel research presents important insights into the potential effects of participants' demographic profiles on their view of the importance of identified barriers.

  • Artificial intelligence-based automatic visual inspection system for built
           heritage
    • Authors: Lukman E. Mansuri, D.A. Patel
      Abstract: Heritage is the latent part of a sustainable built environment. Conservation and preservation of heritage is one of the United Nations' (UN) sustainable development goals. Many social and natural factors seriously threaten heritage structures by deteriorating and damaging the original. Therefore, regular visual inspection of heritage structures is necessary for their conservation and preservation. Conventional inspection practice relies on manual inspection, which takes more time and human resources. The inspection system seeks an innovative approach that should be cheaper, faster, safer and less prone to human error than manual inspection. Therefore, this study aims to develop an automatic system of visual inspection for the built heritage. The artificial intelligence-based automatic defect detection system is developed using the faster R-CNN (faster region-based convolutional neural network) model of object detection to build an automatic visual inspection system. From the English and Dutch cemeteries of Surat (India), images of heritage structures were captured by digital camera to prepare the image data set. This image data set was used for training, validation and testing to develop the automatic defect detection model. While validating this model, its optimum detection accuracy is recorded as 91.58% to detect three types of defects: “spalling,” “exposed bricks” and “cracks.” This study develops the model of automatic web-based visual inspection systems for the heritage structures using the faster R-CNN. Then it demonstrates detection of defects of spalling, exposed bricks and cracks existing in the heritage structures. Comparison of conventional (manual) and developed automatic inspection systems reveals that the developed automatic system requires less time and staff. Therefore, the routine inspection can be faster, cheaper, safer and more accurate than the conventional inspection method. The study presented here can improve inspecting the built heritages by reducing inspection time and cost, eliminating chances of human errors and accidents and having accurate and consistent information. This study attempts to ensure the sustainability of the built heritage. For ensuring the sustainability of built heritage, this study presents the artificial intelligence-based methodology for the development of an automatic visual inspection system. The automatic web-based visual inspection system for the built heritage has not been reported in previous studies so far.

  • Barriers for implementing solar energy initiatives in Nigeria: an
           empirical study
    • Authors: Dahiru Abdullahi, Suresh Renukappa, Subashini Suresh, David Oloke
      Abstract: Despite the abundant renewable energy potential in the Nigeria, the power-sector stakeholder has not paid attention to the prospect of the natural resources that can be accrued when it is properly harnessed. Although a very negligible fraction of the population has invested in solar photovoltaics (PVs) for home solution, the initiative was only made public commercialised under the public-private partnership (PPP) and the objectives of the Power Sector Reform Act. 2005. It is, therefore, aimed to investigate the causes and insight of the barriers that are responsible for the slow implementation of the solar energy initiative in the Nigeria. An empirical study was performed in the Nigeria. The study was conducted qualitatively, through semi-structured face-to-face interviews of 25 participants. The interviews were recorded, transcribed, interpreted, coded, categorised into themes and analysed by content analysis. The study reveals technological, financial, political and social barriers have been the reason for slowing down solar energy development in Nigeria. While the technical barrier is a challenge to the solar energy implementation, socio-cultural issues have also been an obstacle to the implementation process. It is suggested that, the stakeholders of the initiative endeavour to proffer sustainable policies to enable public and private promoters to be able to generate and distribute electricity through solar PV and to complement the inadequate conventional electricity sources from the grids. The paper provides a richer insight into the understanding and awareness of barriers for implementing solar energy strategies in Nigeria.

  • Ecological houses of Southern Kazakhstan using renewable energy sources
    • Authors: Ardasher Namazbay Yussupov, Akmaral Ardasherovna Yussupova
      Abstract: The purpose of this article discusses the design of underground eco-houses using a dome structure of light construction while taking into account the historical experience of the development of the local population. This article considered the traditions of folk architecture and modern sophistication in the creation of energy-efficient eco-houses in foreign countries in the context of architecture and construction of affordable residential homes for the local population. The research presented in this paper was motivated by the need for developing agro-tourism facilities in hard-to-reach areas of the Silk Road in Southern Kazakhstan causes the construction of eco-houses built using local construction materials. Since ancient times in Southern Kazakhstan and during seasonal migrations in yurts of light construction, people have lived in mud-brick houses deep in the ground. Along with architectural and artistic solutions in building construction, great importance was attached to saving material resources, labour costs and achieving heat stability of residential buildings. In the architectural and planning solution of the eco¬-house, progressive directions of construction of agrotechnical structures using renewable energy sources are adopted. Particular importance was given to the choice of the construction site on an elevated area nearby historical monuments and a favourable season for the construction of eco-houses with considering the natural and climatic characteristics of rural areas of Southern Kazakhstan. This paper discussed the issues of insulation, ventilation and improving the eco-house microclimate comfort using local building materials. Improving the architectural and artistic expressiveness of the eco-house in terms of the tradition of folk architecture was also explicitly discussed in this paper. Tables with the justification of expediency of construction of economical eco-houses in natural and climatic conditions of Kazakhstan and Central Asia are provided. The results help to improve the energy efficiency of eco-houses in Kazakhstan by using renewable energy sources. Social benefits are associated with the use of local raw materials. Eco-houses built from traditional building materials can become accessible to a wide range of people and stimulate the development of small businesses. This may be associated with the construction of eco-houses to serve visiting tourists in remote picturesque oases, as well as the manufacture of dome structures, felt products and the preparation of reed panels and so on. The thermotechnical characteristics of the region's ground energy are given, which can significantly save the cost of heating the eco-house. Solutions for optimal insolation, ventilation of the eco-house are provided, taking into account the natural and climatic conditions of Southern Kazakhstan.

  • Emissions in different stages of economic development in nations
    • Authors: Amulya Gurtu, Anandajit Goswami
      Abstract: This paper analyzed country-wise energy consumption, sources of emissions, and how it gets impacted by their socioeconomic development and provides a framework for integrated climate and development policy. An analysis of energy supply, consumption and emissions across developed and developing economies using long-term empirical data. The framework provided areas to be focused on reducing emissions during the economic and social development trajectory of nations. It provides a holistic and integrated picture of the context of emissions that induced global warming and developmental challenges for different types of countries. All nations must reduce fossil fuel consumption to reduce anthropogenic greenhouse gas (GHG) emissions to keep the planet's temperature rise within 1.5 degrees Celsius compared to the preindustrial period. Sustainable/green technologies might need upfront investment to implement sustainable technologies. The main contribution of this paper is to provide a long-term integrated perspective on energy demand and supply, emissions, and a framework for the formulation of an integrated climate and development policy.

    • Authors: M. Reza Hosseini, Julie Jupp, Eleni Papadonikolaki, Tim Mumford, Will Joske, Bahareh Nikmehr
      Abstract: This position paper urges a drive towards clarity in the key definitions, terminologies and habits of speech associated with digital engineering and building information modelling (BIM). The ultimate goal of the paper is to facilitate the move towards arriving at an ideal definition for both concepts. This paper takes the “explanation building” review approach in providing prescriptive guidelines to researchers and industry practitioners. The aim of the review is to draw upon existing studies to identify, describe and find application of principles in a real-world context. The paper highlights the definitional challenges surrounding digital engineering and BIM in Australia, to evoke a debate on BIM and digital engineering boundaries, how and why these two concepts may be linked, and how they relate to emerging concepts. This is the first scholarly attempt to clarify the definition of digital engineering and address the confusion between the concepts of BIM and digital engineering.

  • The renaissance of augmented reality in construction: history, present
           status and future directions
    • Authors: Ke Chen, Fan Xue
      Abstract: Augmented reality (AR) has become one of the most promising technologies in construction since it can seamlessly connect the physical construction environment and virtual contents. In view of the recent research efforts, this study attempts to summarize the latest research achievements and inform future development of AR in construction. The review was conducted in three steps. First, a keyword search was adopted, and 546 papers were found from Scopus and Web of Science. Second, each paper was screened based on the selection criteria, and a final set of 69 papers was obtained. Third, specific AR applications and the associated technical details were extracted from the 69 papers for further analysis. The review shows that: (1) design assessment, process monitoring and maintenance management and operation were the most frequently cited AR applications in the design, construction, and operation stages, respectively; (2) information browser and tangible interaction were more frequently adopted than collaborative interaction and hybrid interaction; and (3) AR has been integrated with BIM, computer vision, and cloud computing for enhanced functions. The contributions of this study to the body of knowledge are twofold. First, this study extends the understanding of AR applications in the construction setting. Second, this study identifies possible improvements in the design and development of AR systems in order to leverage their benefits to construction.

  • Potential integration of blockchain technology into smart sustainable city
           (SSC) developments: a systematic review
    • Authors: Phui Fung Wong, Fah Choy Chia, Mee San Kiu, Eric C.W. Lou
      Abstract: Prior literature lacks concrete and systematic review of the current blockchain application in smart sustainable city that covered to the full extent of various components. Thus, this study explores the integration of blockchain technology in making the city smarter, safer and sustainable. This study conducted a systematic literature review of 49 publications published globally. Data were analysed by coding of the publications whereby the codes were generated based on frequency of appearance (n). The results showed that smart sustainable city could leverage blockchain technology in several areas such as governance, mobility, asset, utility, healthcare and logistics. Blockchain technology could also aid smart sustainable city in achieving social, environmental and economic sustainability. This study proposes a smart sustainable city with blockchain technology framework: guiding city planners and policymakers by deploying blockchain that supports technology within smart sustainable city framework. This facilitates the digital transformation of a city towards smart and sustainable through the use of blockchain.

  • A framework for the adoption of green business models in the Ghanaian
           construction industry
    • Authors: Theophilus Lamptey, De-Graft Owusu-Manu, Alex Acheampong, Michael Adesi, Frank Ato Ghansah
      Abstract: Despite the amount of considerable investigations on business models, much studies have not been undertaken in the construction industry emphasising the adoption of green business models to drive sustainable construction. Construction activities continue to increase the carbon footprint and eject contaminated materials into the ecological environment with dire consequences for economic and social sustainability. As a result of the adverse impacts of construction activities, it is necessary for construction firms to rethink their approach to the use of conventional business models. The purpose of this study is to explore a framework for the adoption of green business models to drive sustainability in the construction industry of Ghana. This research is exploratory due to its focus on emerging economies in which there is a perceptible gap in the adoption of green business models. As a result of this, this paper is entrenched in the interpretivist philosophical stance, which led to the adoption of the qualitative approach. Semi-structured interviews were undertaken involving 13 senior managers of construction firms. A thematic analysis was used with the aid of qualitative data analysis computer software package to code the interview transcripts. The results demonstrate the six definitions of green business models among the managers of construction firms. The study also shows the need for developing green business models to address the issues of circularity and sustainability goals to reduce carbon footprints in the construction industry. Similarly, the paper found various sources of information to drive the awareness, understanding and adoption of the components for green business models. These sources include international conferences and training workshops on green business models. Finally, the study presents a framework that integrates the building information modelling (BIM) and the Internet of things (IoT) into the components for green business models adoption in construction firms. There is a need to use the quantitative approach to undertake further empirical studies, as this paper focuses mostly on the qualitative approach to ascertain the nature of the relationship between green business model and the various components of the circular economy in the construction industry. The study contributes to the existing knowledge on green business models by demonstrating six key pillars of green business models by the inclusion of digital technologies such as BIM and IoT, which hitherto this investigation have not been considered in the adoption of green business models in the construction industry. This study extends the existing knowledge on green business models, which has the potential to increase the awareness and understanding of practitioners and managers of construction firms.

  • Prioritizing infill structure indicators in a historical context: in terms
           of economic sustainability- the vicinity zone of Tabriz historic bazaar
    • Authors: Mitra Seyyedpour Esmaeilzadeh, Ahad Nejad Ebrahimi, Vahid Vaziri
      Abstract: Sustainability is one of the major factors in the way of creating new structures in historical contexts. The economic principle plays a very significant role in sustainability besides the environmental and social components. Tabriz Historic Bazaar that has been inscribed on the World Heritage list has witnessed various developments in its surrounding area over recent years. The purpose of this study is to analyze the infill structure indicators in this region in terms of economic sustainability. First, based on related literature reviews and approaches, the indicators that should be considered in the creation of infill structures in historical contexts were collected. Later, by considering the vicinity zone of Tabriz Historic Bazaar, the effect of each indicator on the economic sustainability of the building was gathered by means of AHP questionnaires and in-person interviews with experts and analyzed by the Expert Choice software. The findings present a guideline which indicates that the type of materials being used is the most important factor in order to create an economically sustainable infill structure in this setting. Accordance with the Climate of the region ranks second place and the Cultural land-use as the Suitable land use for this site goes for the third. The mentioned guideline includes 25 indicators and can help designers with a clear path. This paper clarifies the order of indicators' importance for enhancing the design and consequently function of infill structures, being built in this historic context, with the aim of economic sustainability. The prioritization of indicators in this research depends mainly on their relevance to the conditions of the study area, but the methodology can be used helpfully in similar cases.

  • Exploring applicability, interoperability and integrability of
           Blockchain-based digital twins for asset life cycle management
    • Authors: Christopher Santi Götz, Patrik Karlsson, Ibrahim Yitmen
      Abstract: The blockchain-based digital twin has been recognized as a prominent technological ecosystem featuring synergies with both established and emergent information management practice. The purpose of this research is to explore the applicability, interoperability and integrability of a blockchain-based digital twin for asset life cycle management and develop a model of framework which positions the digital twin within a broader context of current management practice and technological availability. A systematic literature review was performed to map use cases of digital twin, IoT, blockchain and smart contract technologies. Surveys of industry professionals and analyses were conducted focussing on the mapped use cases' life cycle–centric applicability, interoperability and integrability with current asset life cycle management practice, exploring decision support capabilities and industry insights. Lastly, a model of framework was developed based on the use case, interoperability and integrability findings. The results support approaching digitization initiatives with blockchain-based digital twins and the positioning of the concept as both a strategic tool and a multifunctional on-field support application. Integrability enablers include progression towards BIM level 3, decentralized program hubs, modular cross-technological platform interfaces, as well as mergeable and scalable blockchains. Knowledge of use cases help highlight the functionality of an integrated technological ecosystem and its connection to comprehensive sets of asset life cycle management aspects. Exploring integrability enablers contribute to the development of management practice and solution development as user expectations and technological prerequisites are interlinked. The research explores asset life cycle management use cases, interoperability and integrability enablers of blockchain-based digital twins and positions the technological ecosystem within current practice and technological availability.

  • Sensory and physiological assessment of spatial transient thermal
           environment changes at a tropical university campus
    • Authors: Nur Dalilah Dahlan, Amirhosein Ghaffarianhoseini, Norhaslina Hassan
      Abstract: Recent studies have found that the high demand for air-conditioning usage in tropical countries has affected the thermal adaptability of building occupants to hot weather, and increased building energy consumption. This pilot study aims to investigate the effects of transient thermal environment changes on participants' sensory and physiological responses. The change of thermal perceptions, skin temperatures and core temperatures when exposed to transient thermal environments (cool-warm-cool) from 10 college-aged female participants during a simulated daily commute by foot to class in a tropical university campus were investigated. Subjective measurements were collected in real-time every 5 min. The main finding suggests that participants were acclimatised to cool air-conditioned indoor environments, despite exhibiting significant mean skin temperature differences (p

  • Modelling the yield of 8.64 kW PV panels installed on a rooftop of a
           building in the Kingdom of Bahrain
    • Authors: Naser Waheeb Alnaser, Waheeb Essa Alnaser
      Abstract: This paper allows more accurate estimation of the economy in investing in PV electrification for buildings, especially for Gulf Cooperation Council Countries (GCCC) where they have nearly similar climate and building structure. The actual solar electricity yield from this building is used to make empirical modelling. The accurate automated daily-recorded solar electricity from 8.64 kW solar PV on a rooftop of Sadeem Building at Awali, Bahrain, was modelled to polynomial equations of order of 6. The effect of the tilt (β) and azimuth (Ψ) angle of PV panels for smart and sustainable buildings is studied. The correlation of each set of polynomial equation (R2) is listed and had reached a highest value of 0.9792 (for order of 6) with lowest value of 0.1853 (for order of 1). The model may be also applied to the GCCC. The results show that each kW of PV will have a solar electricity yield, on average, of 4.1 kWh. It also shows that the tilt angle has little influence on the solar electricity yield (less than 10%) when the tilt angle changed from 26° to 0° or from 26° to 50°. The influence of the azimuth angle is found to be more than 50% in changing Ψ from 90° to 180°. The model may not be restricted to Bahrain but applies – to a certain extent – to GCCC (six countries) and to other countries having buildings with similar roof design and at latitude close to the latitude of Bahrain. The model enables developers and investors to estimate, with high accuracy, the solar electricity provided from a building if PV panels are to be installed on its rooftop (or facade) at different tilt (β) and azimuth (Ψ) angle for smart and sustainable buildings. Empirically finding out how much each kW of solar PV integrated to the building will produce solar energy electricity (in kWh), that is, 1 kW of PV yield, on average, 4.1 kWh. Establishing empirical models to evaluate the outcome of each installed kW of PV panels. Each 1 kW installation of PV panels is 4.0 kWh/day, on average. This is less than what commercial companies claim for this region, that is, 1 kW produces 5.5 kWh/ day – which affects the estimated economic outcome of PV projects.

  • Deploying ecosystem services to develop sustainable energy landscapes: a
           case study from the Netherlands
    • Authors: Paolo Picchi, Simone Verzandvoort, Davide Geneletti, Kees Hendriks, Sven Stremke
      Abstract: The transition to a low carbon future is an emerging challenge and requires the planning and designing of sustainable energy landscapes – landscapes that provide renewable energy while safeguarding the supply of other ecosystem services. The aim of this paper is to present the application of an ecosystem services trade-off assessment in the development of sustainable energy landscapes for long-term strategic planning in a case study in Schouwen-Duivenland, The Netherlands. The application consists in three activities: in (1) stakeholder mapping hot spots of ecosystem services and renewable energy technologies in a workshop, (2) landscape design principles being discussed by a focus group, (3) experts gathering the information and proceeding with an assessment of the potential synergies and trade-offs. The case study indicates that (1) deploying the ecosystem services framework in planning and design can enhance the development of sustainable energy landscapes, (2) diversified and accurate spatial reference systems advance the trade-off analysis of both regulating and cultural ecosystem services and (3) the involvement of local stakeholders can advance the trade-off analysis and, ultimately, facilitates the transition to a low-carbon future with sustainable energy landscapes. The originality of this research lies in the creation of an approach for the deployment of ecosystem services in the planning and design of energy transition. This is useful to advance energy transition by enhancing research methods, by providing methods useful for planners and designers and by supporting communities pursuing energy self-sufficiency in a sustainable manner.

  • Driving sustainable construction development through post-contract key
           performance indicators and drivers
    • Authors: Terence Y.M. Lam
      Abstract: This research examines what key performance indicators (KPIs) and drivers should be applied at the post-contract phase of construction development to monitor and drive project outcomes in sustainable design and construction. It supplements the previous research which focuses on pre-contract sustainable procurement of competent professionals. Consequently, optimal sustainability can be achieved for the overall sustainable development process. A review of empirical work was conducted to consolidate the holistic aspects of sustainability that should be considered for design and construction and their project outcome KPI measures. Based on a country-wide questionnaire survey of the university estate sector in the UK, a quantitative hierarchical regression analysis was conducted to identify the performance drivers for those KPIs. The empirical work review demonstrates that holistic sustainability for development can be measured by project outcome KPIs: economic sustainability by cost KPIs; functional, social and environmental sustainability by quality KPIs. The quantitative hierarchical regression analysis confirmed that these four aspects of sustainability could be significantly driven by task performance and contextual performance drivers, as supported by the job performance theory. The investigation was undertaken within the context of university estates forming a unique public sector in the UK. The findings form a baseline upon which further research can be conducted in other organisations in the wider public and private sectors. Ultimately, holistic sustainability can be fully driven by construction professionals to achieve government and corporate construction strategy for the benefits of sustainable built environment. The findings inform project managers and construction professionals that they should apply clear, measurable cost and quality KPIs and focus on significant performance drivers in tandem to drive holistic sustainability for design and construction. Project staff should have a high commitment, technical expertise and experience, execute the project with proper design and management methods and provide a high level of trust and collaboration to the client. Clients, designers and contractors are key stakeholders in the development process so they should be consulted for forming the contract KPIs to monitor the sustainable project outcomes. The generalised results confirm that task and contextual performance drivers can be applied as project management tools for managing the professional team members to achieve sustainability deliverables in terms of KPIs. Such findings will enhance the government or corporate construction strategy for managing and achieving holistic sustainability for construction developments. This research identifies post-contract performance monitoring measures (cost and quality KPIs as well as task and contextual performance drivers) that can be adopted for driving sustainable design and construction for sustainable development.

  • A fuzzy synthetic evaluation of the challenges of smart city development
           in developing countries
    • Authors: Douglas Omoregie Aghimien, Clinton Aigbavboa, David J. Edwards, Abdul-Majeed Mahamadu, Paul Olomolaiye, Hazel Nash, Michael Onyia
      Abstract: This study presents a fuzzy synthetic evaluation of the challenges of smart city realisation in developing countries, using Nigeria as a case study. By defining and delineating the problems faced by the country, more viable directions to attaining smart city development can be achieved. The study adopted a post-positivist philosophical stance with a deductive approach. A structured questionnaire was used to gather data from built environment professionals involved in the delivery of Nigerian public infrastructures. Six dimensions of the challenges of smart cities were identified from literature and explored. They are governance, economic, social, technological, environmental and legal issues. Data gathered were analysed using Cronbach alpha test for reliability, Shapiro-Wilks test for normality, Kruskal-Wallis H-test for consistency and fuzzy synthetic evaluation test for the synthetic evaluation of the challenges of smart city attainment. The findings revealed that all six assessed dimensions have a significant impact on the attainment of smart cities in Nigeria. More specifically, issues relating to environmental, technological, social and legal challenges are more prominent. The fuzzy synthetic approach adopted provides a clear, practical insight on the issues that need to be addressed before the smart city development can be attained within developing countries.

  • Assessment of direct evaporative cooler performance with a cooling pad
           made from banana midrib and ramie fiber
    • Authors: Hery Sonawan, Evi Sofia, Arief Ramadhan
      Abstract: The paper aims to apply Buckingham Pi dimensional analysis method for assessing direct evaporative cooler performance with a cooling pad made of banana midrib and ramie fiber. The saturation efficiency acted as the indicator performance of the evaporative cooler. The paper describes an experimental study of the direct evaporative cooler with a cooling pad made of banana midrib and rami fiber. There were six parameters in the experiment: absorbed water as a dependent variable was affected by independent parameters such as air velocity and temperature, cooling pad cross-section area and thickness. Based on these variables, we arranged three dimensionless numbers and their correlation. The paper provides three calculated dimensionless numbers plotted on a curve with a specific correlation. The curve trends for 30 mm and 50 mm pad thickness were almost similar. The range of Reynolds number for 10 mm pad was narrower than other pad thicknesses. The thicker the cooling pad, the more extensive was the calculated Reynolds number range. A new curve exhibited the relationship between the evaporation rate with the μA/t number. The broader cooling pad cross-section, the thinner pad thickness, and the lower pad temperature were factors that increased the evaporation rate, even though the increase was less significant. A new material in cooling pad from banana midrib fiber was tested and compared to ramie fiber and conventional cooling pad.

  • Barriers to green cities development in developing countries: evidence
           from Ghana
    • Authors: Caleb Debrah, De-Graft Owusu-Manu, Ernest Kissi, Eric Oduro-Ofori, David John Edwards
      Abstract: Of late, cities across the globe are taking pragmatic steps towards addressing environmental, social and economic problems in the debate on sustainable development. Even so, little attention has been paid to studies focused on developing countries. The aim of this study is to examine the barriers to green cities development in developing countries. A comprehensive literature review was conducted to examine the barriers to green cities development. In terms of methodological choice, a quantitative research strategy was used to collect data from professionals who have lines of influence on the greening of our cities and sustainable urban development. The barriers to green city development identified were lack of awareness of the benefits of a green city, environmental degradation, insufficient policy implementation efforts, excessive generation of solid waste and poor wastewater collection and treatment. It was indicative from the study findings that taking the right sustainable steps in urban development and a paradigm shift towards the pillars of sustainability, Ghanaian cities, especially Kumasi, have a great proclivity of regaining its longstanding status being “Garden City”. The outcome of this study provides stakeholders in city development an insight into the barriers that inhibit the development of green cities. In practice, this study contributively proposes that the concept of green cities should be incorporated in the education and training of stakeholders to improve the level of awareness. This paper presents the foremost comprehensive study appraising green city development in Ghana.

  • Towards sustainable commercial buildings: an analysis of operation and
           maintenance (O&M) costs in Sri Lanka
    • Authors: Achini Shanika Weerasinghe, Thanuja Ramachandra, James O. B. Rotimi
      Abstract: Rising energy costs and increasing environmental concerns are catalysts for introducing sustainable design features in buildings. Incorporating sustainable design features in commercial buildings cannot be overstated because it could confer benefits to the investor (owners) and occupants. This study aims to develop a model that could aid in the prediction of operation and maintenance (O&M) costs from the knowledge of building-design variables. There is little evidence that design variables influence the O&M costs of buildings. Therefore, this study investigates the relationship between design variables and O&M costs in commercial buildings with the intent of developing a cost model for estimating O&M costs at the early design phase. The study was approached quantitatively using a survey strategy. Data for the study were obtained from 30 randomly selected commercial buildings in the CBD in Colombo, Sri Lanka. Pareto's 80/20 rule, correlation and regression analysis were performed on the data to prove the statistical relationships between the buildings' O&M costs and their design variables. The study found that 12 significant O&M costs elements contribute to about 82% of total O&M costs. Repairs and decoration had a strong correlation with building shape. Furthermore, the regression analysis found that O&M costs values were primarily dependent on the building size (the gross floor area and height of the buildings). The gross floor area and height handled over 73% of the variance in the O&M costs of commercial buildings in Sri Lanka. These findings are a useful insight into the principles for design economies that could contribute to more sustainable commercial buildings.

  • Toward digitalization in the construction industry with immersive and
           drones technologies: a critical literature review
    • Authors: Faris Elghaish, Sandra Matarneh, Saeed Talebi, Michail Kagioglou, M. Reza Hosseini, Sepehr Abrishami
      Abstract: In this study, a critical literature review was utilized in order to provide a clear review of the relevant existing studies. The literature was analyzed using the meta-synthesis technique to evaluate and integrate the findings in a single context. Digital transformation in construction requires employing a wide range of various technologies. There is significant progress of research in adopting technologies such as unmanned aerial vehicles (UAVs), also known as drones, and immersive technologies in the construction industry over the last two decades. The purpose of this research is to assess the current status of employing UAVs and immersive technologies toward digitalizing the construction industry and highlighting the potential applications of these technologies, either individually or in combination and integration with each other. The key findings are: (1) UAVs in conjunction with 4D building information modeling (BIM) can be used to assess the project progress and compliance checking of geometric design models, (2) immersive technologies can be used to enable controlling construction projects remotely, applying/checking end users’ requirements, construction education and team collaboration. A detailed discussion around the application of UAVs and immersive technologies is provided. This is expected to support gaining an in-depth understanding of the practical applications of these technologies in the industry. The review contributes a needed common basis for capturing progress made in UAVs and immersive technologies to date and assessing their impact on construction projects. Moreover, this paper opens a new horizon for novice researchers who will conduct research toward digitalized construction.

  • Developing a building performance score model for assessing the
           sustainability of buildings
    • Authors: Thanu HP, Rajasekaran C, Deepak MD
      Abstract: Construction industry is one of the leading causes of pollution generation in today's context. But the fact that the development of construction industry leads to the country's economic and social development cannot be unobserved. Hence, there is a need to develop a sustainable construction methodology, and while doing so, measures must be considered so as to not disturb the natural habitats. With the greater prominence shown toward the concept of green and sustainable construction developments, various tools have been developed in recent years in order to measure the performance of such sustainable and green buildings. In the Indian context, the assessment tools developed to measure the performance of the green building are found to be scanty in addressing various economic and social impacts. This study aims at developing a building performance score (BPS) model concerning the sustainability model built on the triple bottom priorities considering all the three vital components, viz. environmental, economic and social factors. In this study, the different phases involved in the complete life cycle of the project are recognized and then all the phases are assessed considering all the three major components mentioned in the BPS model. The outcome of this study specifies that various indicators, such as the topographical and climate change, health and safety of the construction workers, project management consultancy, risk management, security measures and solid waste management, form a chief source of a sustainable building, and these indicators are not being assessed in the existing assessment tools. Also, consideration of environmental, economic and social factors is also equally important in construction industry. Moreover, these indicators are also required to be assessed and included in the evaluation process while assessing the performance of the building. The BPS model developed in the study will assist to improve in assessing the building performance with respect to all indicators in the complete life cycle of the project.

  • Underlying indicators for measuring smartness of buildings in the
           construction industry
    • Authors: Frank Ato Ghansah, De-Graft Owusu-Manu, Joshua Ayarkwa, Amos Darko, David J. Edwards
      Abstract: This study investigates the underlying indicators for measuring the smartness of buildings in the construction industry; where the Smart Building Technology (SBT) concept (which incorporates elements of the Zero Energy Building (NZEB) concept) could ensure efficient energy consumption and high performance of buildings. An overarching post-positivist and empirical epistemological design was adopted to analyze primary quantitative data collected via a structured questionnaire survey with 227 respondents. The mean ranking analysis and one-sample t-test were employed to analyse data. Research findings revealed that the level of knowledge of smart building indicators is averagely high in the Ghanaian construction industry. Future research is required to evaluate the awareness level of Smart Building Technologies (SBTs) by construction professionals and identify barriers to its adoption. A blueprint guidance model (consisting of significant indicators for measuring building smartness) was developed to help improve building performance and inform policymakers.

    • Authors: Solomon Olusola Babatunde, Damilola Ekundayo, Chika Udeaja, Uthman Olawande Abubakar
      Abstract: In the global construction industry, the concept of sustainability is not new, particularly within building projects. Against this backdrop, several studies have been conducted, mostly in developed countries, on sustainability in construction projects. However, efforts at investigating sustainability practices in public–private partnership (PPP) infrastructure projects in developing countries have received limited attention. Hence, the purpose of this study is to investigate the incorporation of sustainability practices within the context of Nigeria’s PPP infrastructure projects. A questionnaire survey, which targeted four different types of stakeholders, was conducted in this study. These stakeholders included public sector authorities, concessionaires, consultants and banks undertaking PPP infrastructure projects in the Lagos State, Nigeria. The data collected were analyzed using frequency, percentage, mean score, standard deviation (SD) analyses and the Kruskal–Wallis test. The findings of this study revealed that all the respondents are very much aware of sustainability principles and the vast majority of the respondents from the public sector authorities and the consultant organizations confirmed that they have incorporated sustainability requirements into their bidding documents for PPP infrastructure projects. The study revealed sustainability features in the three aspects of sustainability, namely, economic, environmental and social factors. Furthermore, the study revealed the top three–ranked economic factors of sustainability (considered to be the most important factors) were low maintenance costs, whole life costing and supporting the local economy, respectively. Similarly, the study revealed the top three–ranked environmental factors of sustainability were biodiversity, energy use during the operation stage and energy use during the construction stage, respectively. Furthermore, the study further revealed that the top three–ranked social factors of sustainability were the educational aspect, equity between stakeholders and health and safety, respectively. The study will be of great value to PPP stakeholders involved in sustainability decision-making processes when delivering sustainable PPP projects, particularly in Nigeria. Also, the study’s findings are important as not many empirical studies have been conducted on the sustainability practices of current PPP projects in Nigeria. The study’s findings would further inform the need for both the public and private sectors to take a more strategic approach to enhance sustainability in PPP projects.

  • A systematic review of circular economy research in the construction
           industry
    • Authors: Oluyomi A. Osobajo, Adekunle Oke, Temitope Omotayo, Lovelin Ifeoma Obi
      Abstract: While circular economy (CE) is fast becoming a political and economic agenda for global urban development, there are still substantial knowledge gaps in possible strategies to speed up such transition, especially in the construction industry. This study analyses literature surrounding CE to unpack current trends possible future research directions to foster CE implementation in the construction industry. The study undertakes a systematic review of CE literature published between 1990 and 2019. It adopts a five-stage procedure as a methodological approach for the review: formulation of the research question(s), locating and identifying relevant studies, selection and evaluation of studies, analysis or synthesis and results reporting. The findings on CE research in the construction industry show extensive focus on resource use and waste management. There are limited investigations in other areas of construction such as supply chain integration, building designs, policy, energy efficiency, land use, offsite manufacturing, whole life costing, and risk, cost reduction, cost management, health and safety management. The study findings provide evidence that current CE practice fails to incorporate other areas that would facilitate the network of true circular construction industry. This research provides a comprehensive overview of research efforts on CE in the construction context, identifying areas of extensive and limited coverage over three decades. Besides, it identifies possible pathways for future research directions on CE implementation, towards the accelerated transition to a true circular construction industry for the benefit of funding bodies and researchers.

  • Development of a sustainability rating tool for heritage buildings: future
           implications
    • Authors: Abobakr Al-Sakkaf, Tarek Zayed, Ashutosh Bagchi, Sherif Mahmoud, David Pickup
      Abstract: Heritage buildings are significant for their historical and architectural value. Due to the lack of rating systems designed specifically for heritage buildings, it is essential to develop and validate a heritage building assessment tool that considers its specific characteristics. The purpose of this study is to provide an extensive review of research on Sustainability of Heritage Buildings (SHBs). This review highlights methodologies applied in SHBs research and analyzes major global rating systems in order to identify their deficiencies for SHBs assessment. A systematic review was employed and articles from the top 10 high impact factor journals were studied. Twelve major global rating systems and their assessment criteria were identified. Significant variability was observed among the assessment tools since each tool assesses several criteria, factors and indicators that fit its local context. Part of this variability can also be seen in the rating scales, threshold values and accreditation titles. As a result, the final sustainability ranking for a given building cannot be compared among the 12 rating systems. Most importantly, these systems fail to analyze some factors such as energy that are considered important with respect to heritage building assessment. Since no specific rating system could be identified in this review as the most appropriate for heritage buildings, a new sustainability assessment tool that is specific to heritage buildings should be developed. Such a tool will enable facility managers to evaluate and improve the sustainability of their heritage buildings while preserving them.

  • A structural equation modeling analysis of factors driving customer
           purchase intention towards solar water heater
    • Authors: Vikas Kumar, Amanjot Singh Syan, Komalpreet Kaur
      Abstract: The underlying research is an attempt to discover the factors responsible for influencing customer purchase intention towards solar water heaters. Six dimensions have been considered to assess customer purchase intention towards a solar water heater. The primary data involves the responses collected from 695 respondents belonging to the north region of India using a convenience sampling technique. Structural equation modeling analysis has been employed to examine the dimensions' impact on customer purchase intention. The results concluded that dimensions such as increasing energy prices, product knowledge and experience, financial support and subsidies, perceived cost, have a positive influence on customers' purchase intention of solar water heater except for the dimension of “solar water heater aesthetics”. Due to the limited sample size, findings cannot be generalized for the large-scale population. Moreover, this study is only confined to the assessment of particular factors that are affecting the purchase intention of customers confined to solar water heaters only. The present study will provide an advantage to organizations that are in the process of implementing solar energy products into working. Moreover, this research will also assist policymakers regarding the formulation of policies on solar energy products. An undue advantage of this would be the increasing adoption of a solar water heater by understanding the factors that impact customer purchase intention. Considerably, this research, by filling up the gap in the existing studies, will empirically contribute to the customer purchase intention towards SWHs. Additionally, the results of the study will also endow an additive advantage to the existing firms.

  • Studying the institutional framework for the public transport system in
           Jaipur, India
    • Authors: Mohit Dev, Arindam Biswas
      Abstract: The objective of this study is to understand the institutional dynamics of the public transport system in Jaipur. The institutional dynamics of the public transport system includes an understanding of the role of the formal and informal institutions (i.e. the actors) and the relationship between the public bus, external and private city bus operators. The research methodology to achieve the objectives of the study included an institutional mapping method to develop an in-depth understanding of the existing institutional framework for the public transport, secondary data and primary survey processed through focused interviews of Jaipur City Transport Services Limited (JCTSL) and the Regional Transport Office (RTO) officials, representatives of the external operator, drivers and conductors’ union and private city bus service operators. The cooperation level between these organizations was measured on a five-point Likert scale. The study indicated significant issues: poor cooperation levels between JCTSL and the RTO; the absence of a horizontal relationship between JCTSL and the RTO; conflict of powers, the competition of public and private minibus service; delays in smart city projects; absence of an integrated transport authority. In the Indian context, this study can help other Indian cities which are facing similar problems due to the fragmented institutional framework for public transport services and financial losses to the public bus operators due to the direct competition from paratransit or private bus services.

  • Indicators to measure the performance of sustainable urban
           entrepreneurship: an empirical case study applied to Portuguese cities and
           towns
    • Authors: Mário Franco, Margarida Rodrigues
      Abstract: Urban sustainability is an inseparable dimension of today's cities; thus, the role played by creativity, and consequently sustainable urban entrepreneurship and the networks it raises, gives rise to the pro-activity of these two constructs toward a tripartition (economic, social and environmental). This study aims to measure sustainable urban entrepreneurship through a composite of existing indicators in the literature of cities. In this study, the authors followed a quantitative research by applying exploratory factor analysis. The sample contains 308 towns and cities in Portugal, and the data were collected using secondary databases (e.g. INE; PORDATA). Through quantitative research, this study identified the key indicators that mediate sustainable urban entrepreneurship in cities, as a methodological tool for them to evaluate their sustainable entrepreneurial capacity. The results obtained here provide information to show that sustainable urban entrepreneurship is an essential construct for cities, allowing a solution to many of their urban problems by its association with creative economy and its influence on the revitalization of urban spaces by urban regeneration, and by the importance of networks in these, the latter being another fundamental construct. This research makes important contributions to studies considering the sustainability construct in urban entrepreneurship area. It will help to fill part of the gap in existing studies involving the cities’ aspects in entrepreneurship field. Consequently, the main contribution of this study lies in identifying the indicators that contribute to cities' tripartite sustainable balance by assuming sustainable urban entrepreneurship as a crucial premise.

  • Maintenance management practices for green building projects: towards
           hybrid BIM system
    • Authors: Zul-Atfi Ismail
      Abstract: In general, maintenance management is considered as part of the construction sector for the larger service of post-construction activity and process. However, as green building (GB) construction projects grow in scale and complexity, interconnections between the mentioned activities and processes can be noticed in a problematic planning performance management to monitor the GB components for the corrective and preventive maintenance action. Issues often arise during construction activity and pose a problem for the society due to the poor and improper maintenance execution, such as the recent fire in the Grenfell Tower (14 June 2017, about 80 fatalities). The concept of maintenance management practices of GB and main features of Information and Communication Technology (ICT) tools and techniques were based on analysis of number of literature reviews in GB scenarios. The research results described are concerned with an integrated system to analyse information and building a decision-making support in maintenance planning in GB based on robust data collection about concrete failures and causes, provide appropriate planning decision and reduce risks of GB failure throughout the lifetime. The paper concludes that implementing a research framework for developing such a system can help improve the performance of maintenance planning of GB design, construction and maintenance operations.

  • Managers' risk perception and the adoption of sustainable consumption
           strategies in the hospitality sector: the moderating role of stakeholder
           salience attributes
    • Authors: Rasha ElShafei
      Abstract: This study investigates the relationship between managers' risk perception and the adoption of sustainable water consumption strategies and analyzes the moderating effect of stakeholders' salience attributes on this relationship. A conceptual framework that builds on the stakeholder theory was developed to illustrate the direct and moderating role of the study variables. The derived hypotheses were tested quantitatively using multiple regression analysis. Results indicate that managers' risk perception and the three stakeholder salience attributes were significantly associated with sustainable water consumption strategies, and that the legitimacy attribute was a successful moderator between the study variables. The limited ability to generalize results as the study is centered on the hospitality sector. Although the results were comparable to other studies, it is not possible to claim that the findings represent the views of the majority of managers in different industry sectors. The research highlights to managers in the hospitality sector, the significant influence of risk perception and stakeholder salience attributes on the adoption of sustainable water consumption strategies. The research revealed that media, consumers and competitors are powerful, legitimate and urgent stakeholders, respectively. Therefore, the research findings will guide policymakers and nonprofit organizations to support those stakeholders in order to strengthen their power, legitimacy and urgency attributes. Although it has been claimed that risk perception has the potential to influence sustainable consumption of natural resources, few studies empirically investigated the association of risk perception of a specific environmental threat with responsible consumption. Moreover, even though there is general agreement in the literature that the adoption of sustainable water consumption strategies is shaped by the degree to which stakeholders exercise their salience attributes, studies that empirically examine the influence of these attributes within the hospitality sector are lacking. Therefore, this study fills a gap in the current literature by empirically examining the influence of managers' risk perception and stakeholder's salience attributes on firms' adoption of sustainable consumption strategies.

  • Performance assessment of governance in Indian smart city development
    • Authors: Kranti Kumar Maurya, Arindam Biswas
      Abstract: India is set to develop a hundred smart cities under Smart Cities Mission (SCM). New Special Purpose Vehicles (SPV) established at the city level are developing these cities. Cities around the globe do not use this system for city development yet. SCM was launched in 2015, and these companies are working in some of these cities since 2016. This paper is an attempt to investigate the traditional system and SPV system with global best practices. The method for investigation includes developing a framework with the governance principles (defined by the United Nations Development Programme) and measurement parameters. By this framework, the performance of these governance systems can be measured/ranked; analysing these results give the nodal points where one system is better than the other and highlighting features; those can be incorporated to develop an alternative comprehensive system. The new service delivery mechanism (SPV) is still adapting and competing with the traditional system. There have been some positives as well as some criticism for SPVs in comparison to the traditional system. The data for analysis is mostly from secondary sources and structured official interviews. The cases selected for the analysis are cities from different states of India and some leading global cities. Smart cities development is still going on. As the analysis findings suggest, it needs a more efficient and converged implementation mechanism. The analysis framework is solely developed for this paper. The paper compares five of the Indian traditional city development process, SCM implementation strategy and leading city development processes around the world.

           country
    • Authors: Aradhana Vikas Gandhi
      Abstract: The study aims to explore the parameters that affect the purchase behavior of green consumers. A mixed methodology concurrent study was adopted involving questionnaire-based empirical study along with a qualitative study to capture the lived experiences of the respondents. Inferences were drawn to understand green consumer behavior in a holistic way. While conducting in-depth interviews, many recurring themes emerged, such as environmentally friendly, health-conscious, price, government initiatives, youngsters' inclination, general awareness, family influence/traditions, quality, advertisement and social concern. A concurrent quantitative study was conducted, which established altruism, environmental awareness and social factor and influence as significant parameters, which had an impact on green consumer behavior. While designing green products, this study will enable marketers to innovate their products and services based on the intricate insights that have come out of the study. The study seeks to give deep insights into green consumer behavior that may help academics and marketers to understand the phenomenon better.

  • Structure and properties of modified gypsum binder
    • Authors: G.I. Yakovlev, A. Gordina, Rostislav Drochytka, A.F. Buryanov, Olga Smirnova
      Abstract: The purpose of the study is regarding the development of eco-oriented technologies for obtaining the building gypsum materials with the involvement of industrial by-products or waste. The scanning electron microscopy, X-ray microanalysis and IR spectral analysis were used to study the structure of gypsum matrix. The method of comparison of modified and unmodified gypsum matrix was used. Physical modeling of gypsum matrix crystallization is used to study changes in the morphology of hydration products. The experimental results show that the addition of technical soot into a gypsum binder leads to a change in the morphology of crystalline hydrates of calcium sulfate dihydrate. Results of the scanning electron microscopy, X-ray microanalysis and IR spectral analysis confirm the change of physical and mechanical characteristics of the gypsum binder due to the structural modification of the gypsum matrix with ultrafine carbon soot. The achieved degree of the structural modification of the gypsum matrix is compatible with the results obtained when the gypsum binder was modified with dispersions of carbon nanotubes. The morphology of the crystalline hydrates of the gypsum matrix with the addition of 0.04%, 0.06% and 1% of the carbon soot is characterized by the transition of the classical needle-like structure of gypsum dihydrate to the lamellar structure of increased density. One can observe the formation of intergrowths around ultrafine carbon soot particles. The studied carbon additive can improve strength characteristics of the gypsum matrix.

  • Sustaining community infrastructure through community-based governance
           (the social practice of collective design policy)
    • Authors: Job Taiwo Gbadegesin, Samson Ojekalu, Taiwo Frances Gbadegesin, Markson Opeyemi Komolafe
      Abstract: This paper empirically provides information on community-driven infrastructure provision through the collective efforts of community-based organizations (CBOs). It offers an insight into emerging events on community-based infrastructure procurement, scholarship and, creating gaps for new frontiers of knowledge on community development research agenda in the emerging economies. It is drawn upon community-based associations, herein referred to as landlords-landladies community association (LLCAs) – representatives of households in the communities. After interviewing the key members of the groups, we administered copies of the semi-structured questionnaire randomly on the enumerated regular members of sampled seventeen LLCAs. Data were analyzed using descriptive and inferential statistics. Planning for a sustainable community, protection and security necessity and Government inadequate attention on emerging communities over the years are the main reasons for the joint decision. Electrification, drainage and road top the lists of the projects executed. Major challenges included diversity and inclusiveness. Development projects' design, execution and commission contribute to performance. Also, LLCAs' clarity of duties and purposes and tenure/duration of officials contribute to the overall membership satisfaction on governance structure and leadership. It is limited to the specific reasons for collective efforts, challenges of the participatory movement, membership satisfaction on governance and infrastructure recently procured in the communities. Frontier of studies should be extended to enabling factors. Findings from this study indicate that community-driven governance with the support of the government enhances community-based infrastructure. Potential values of collective action embellished in the concepts of a social movement, active engagement, communalism, grassroots efforts, social cohesion and planning in bringing peoples of diversities together for common goals with less rigorous formalization. The novelty of the research is the exposition on the evidence-based innovative concept of integrating the social practice of participatory design, representing a bottom-up model into infrastructure procurement in community settings.

  • Examining critical perspectives on Building Information Modelling (BIM)
           adoption in New Zealand
    • Authors: Dat Tien Doan, Ali GhaffarianHoseini, Nicola Naismith, Amirhosein Ghaffarianhoseini, Tongrui Zhang, John Tookey
      Abstract: This research aims to explore the perspectives of the key actors in the New Zealand construction industry towards BIM adoption. Specifically, four themes are examined, including what BIM is; BIM knowledge and understanding; benefits of BIM adoption; and challenges/barriers to BIM adoption. A qualitative approach using 21 semi-structured interviews with industry experts was adopted. The results raise a question concerning whether the New Zealand construction industry needs a unique definition of BIM to achieve a clear and consistent understanding amongst construction practitioners. It was found out that most of the construction practitioners in New Zealand are not well aware of BIM, especially the contractors, QSs, supply chain companies and the SMEs. Fourteen potential benefits and ten barriers/challenges to BIM adoption were identified. Individually, time-saving was considered as the most benefit of BIM adoption while BIM understanding was suggested as the most significant barrier by all the interviewees. The research provides valuable insights into BIM understanding as well as recommendations regarding BIM adoption in New Zealand. The results could be considered baseline information for the companies and government to have effective strategies towards BIM adoption. Furthermore, it confirms that characteristics such as benefits and barriers to BIM adoption amongst different countries could be similar. Therefore, it could be useful to analyse the studies, strategies and practices of the pioneer countries in BIM adoption for the implementation.

  • The impact of COVID-19 outbreak on United Kingdom infrastructure sector
    • Authors: Haddy Jallow, Suresh Renukappa, Subashini Suresh
      Abstract: In December 2019, news broke out from the World Health Organisation (WHO), with the first outbreak of coronavirus disease 2019 (COVID-19) in Wuhan, China. On 11 March 2020, the WHO declared COVID-19 to officially be a pandemic. The UK was put under lockdown on the 23 March 2020 by the Prime Minister Boris Johnson, the lockdown introduced strict measures put into place including the restriction for unnecessary working from offices, and only leaving houses if it is deemed essential. Therefore, this paper focusses on the changes that the infrastructure sector has had to undertake in order to adhere to the COVID-19 lockdown rules while being productive. Given the new and unexplored nature of the research problem, a qualitative research methodology was adopted. In total, five semi-structured interviews from three infrastructure sector organisations were conducted to collect data, which was then analysed using thematic analysis for inference and conclusion. The results indicate that the lockdown is proving to be difficult to manage projects as staff members are working from home. This leads to delays on a project activities as many staff members cannot physically go on site and conduct works. The managers are finding difficult to manage their teams. However, technological tools such as video chat and meetings via online platforms have proven to be most effective in communications with project teams. The Building Information Modelling Design has been useful as the 3D design models helps to visualise the project within team meetings in order to comply with the COVID-19 rules and follow social distancing guidelines while still carrying on works. However, induction to any new starter is proving to be difficult to manage with the pandemic and lockdown as it involves a drugs and alcohol test prior to commencing work of that project. This paper provides a rich insight into the understanding and awareness of the impact of COVID-19 and the changes that the infrastructure sector has had to undertake in order to adhere to the lockdown rules while being productive. This study contributes towards informing policymakers on some lessons learnt from the management of the COVID-19 from an infrastructure sector perspective. Furthermore, 12 key implications are drawn for decision-makers within the infrastructure sector business to rethink and act to deal with the pandemic crisis.

  • Development of a conceptual model for evaluating the success of BIM-based
           construction projects
    • Authors: Oluseye Olugboyega, David J. Edwards, Abimbola Olukemi Windapo, Emmanuel Dele Omopariola, Igor Martek
      Abstract: Research into project success (PS) has a long pedigree as has research into the impact of building information modelling (BIM) on projects. Yet, despite the many revealed advantages BIM is known to deliver to projects, the relationship between the level of BIM application within a project, BIM's ability to impact a project at that level and the consequent effectiveness and range of success factors BIM is able to bestow across levels remains unmapped. Given the importance of evaluating the success of BIM-based construction projects (BBCPs) and the necessity to ensure the continual improvement of the BIM process, there is a need to identify the relationship between the level of BIM employed on a project and the specific PS factors that BIM is able to impact at that level. This study puts forward a conceptual model for evaluating the success of BBCPs. A thematic synthesis approach is taken, using Scopus and other databases, and retrieving relevant articles from some 50 journals. Eight success criteria for BBCPs were extracted and categorised according to BIM's ability to impact them across four levels of project application. Mapping BIM's variable impact at these four levels against the eight success factors produces a model for evaluating the PS of BBCPs. The model posits that the success of a BBCP is a function of the extent to which BIM is applied to the project. Moreover, the findings indicate that an increase in the number of PS criteria (PSC) for a BBCP is a derivative of BIM effectiveness, and not BIM impact. This work constitutes seminal research to examine the concept of PS and PSC for BBCPs with the view to developing a model for evaluating the PS of BBCPs.

  • Countering tropical cyclonic storm impacts on low-rise houses
    • Authors: Satyajit Ghosh, Krishna Siddharth Rajasekeran, Billton Joseph Vitus, Sai Aswin Srikanth, Suhaas Mohandas, Ashwin Ganesh Monikantan, Shiv Kulin Contractor
      Abstract: This study investigates the aerodynamics of the airflow over low-rise houses subjected to turbulent cyclonic winds along the South-eastern peninsular India, routinely afflicted by tropical cyclones. The purpose of this paper is to demonstrate how the power of modern computational fluid dynamics (CFD) and its engineering application accentuate decision-making at the planning stage of house designing in vulnerable areas. The Weather Research and Forecasting (WRF) model was used for first simulating the landfall of cyclone Hudhud, a real storm, and its effect in extant and new house designs. Results from the WRF model were utilized to configure further CFD simulations of airflow around house designs. The analyses yielded deep insights, often non-intuitive, into airflow patterns around these houses with disparate roof forms indicating new possibilities in redesigning houses along Indian coastal areas. This study shows that storm-induced high TKE values warranted a fuller CFD-based study. The second major finding showed that for a 90° angle of attack, arguably the most destructive attack angle, a pitched roof (with a pitch angle of 10°) worked best – this is about half the recommended angle sourced from earlier empirical estimates dating back to the British Raj period. There is a thin layer of padded air cushion shielding the roof's vulnerable surface from the storm's most energetic parts. The originality of this research lies in its discourse to systematically resolve the TKE distribution of a cyclone impacting a standalone house. In particular, the study presents a lucid demonstration of all the probable scenarios connecting cyclonic stresses with a roof response, inferred from a careful combination of results garnered from cyclonic storm modelling coupled with CFD analysis. Additionally, the paper also shows a graphic visual representation of the forces induced on different roof designs, presented as a checklist for the first time. This should serve as a ready reckoner for civic authorities involved in disaster management over cyclone-ravaged areas.

  • A BIM-based construction claim management model for early identification
           and visualization of claims
    • Authors: Majid Parchami Jalal, Tayebe Yavari Roushan, Esmatullah Noorzai, Maryam Alizadeh
      Abstract: This study aims at introducing a claim management model based on building information modeling (BIM) for claims that can be visualized in BIM models. Based on the results of a questionnaire survey, 10 claims were identified as claims that can be visualized in BIM models (named hard claims in this study). Then, a BIM-based claim management model was developed and used in a case study. A BIM-based claim management model is represented. The claim management process through this model consists of four steps: (1) extracting project information, identifying conditions prone to claim and storing them into a relational database, (2) automatically connecting the database to building information model, (3) simulation of the claims in building information model and (4) final calculations and report. The proposed model can provide benefits to parties involved in a claim, such as early identification of potential claims, large space for data storage, facilitated claim management processes, information consistency and improved collaboration. There are a few studies on providing solutions to claim management based on BIM process. Hence, the original contribution of this paper is the attempt to set a link between BIM and claim management processes.

  • Towards sustainability practices deployment in building construction
           projects in Nigeria
    • Authors: Michael Gbolagade Oladokun, Inimbom Walter Isang, Fidelis Emuze
      Abstract: With recent extreme weather change from global warming, the ever-increasing volume of waste, and the unsustainable use of natural resources, there is the need to evolve a new way by which building construction projects are constructed to reduce carbon emissions, environmental degradation and excessive resource consumption. It is based on this premise that this paper presents the level of implementation of sustainability practices during building construction projects in Nigeria. This study adopted the mixed methods research approach that involves collecting quantitative and qualitative data through the use of questionnaire and interviews. The numeric data were analysed using descriptive and inferential statistics such average percentages, mean item score, Kruskal–Wallis and Mann–Whitney U tests whereas the textual data were analysed thematically. From the questionnaire survey, the result shows that the awareness level of sustainability practices by construction professionals is high in the study area. Also, the findings indicate that “choosing the right construction method for resource conservation and consideration of the client’s satisfaction” is the major sustainability practices that construction professionals implement in the construction phase of building projects in the study area. Insights from the interviews align with the findings from the questionnaire survey. This study concluded that the awareness level of sustainability practices is high in the study area and “choosing the right construction method for resource conservation” and “consideration of the client's satisfaction” are the major sustainability practices that construction professionals are aware of and is being implemented in the study area. Based on these findings and conclusions reached, it is recommended that construction professionals should improve their knowledge of sustainability to enhance their competence for the effective implementation of sustainability practices during building construction projects in Nigeria.

  • Research on intelligent manufacturing development approach for China's
           local valve industry
    • Authors: Victor Chang, Yuanyuan Kate Xu, Jingqi Zhang, Qianwen Xu
      Abstract: The purpose of this paper is to investigate the current situation of China's local valve industry, the maturity of intelligent manufacturing and the way to promote intellectual development. Firstly, a macro analysis of the valve market environment from the domestic and international perspective was conducted. Secondly, online surveys and in-depth interviews were administered to understand the current status of IM development and future development goals. Finally, case studies were conducted to demonstrate whether the hypothesis of the development approach is feasible. This study finds that the overall maturity level of the local valve industry is still in the planning stage since the local valve industry lacks concentration and is relatively scattered. In addition, the feasible development approach is dependent on smart devices to improve production efficiency, ensure quality management and effectively control costs. The research is conducted and focused on the Yangtze River Delta region instead of the whole country, and the size of the sample is small. Therefore, there may be some characteristics omitted in the analysis. Manufacturers can upgrade to smart manufacturing through intelligent software platforms in order to complete an automatic interaction of data and devices. In addition, manufacturers should complete cross-regional collaborative development through the industrial Internet of things. There is little or none of research work completed for the development strategy of the valve industry internationally. Therefore, research findings of this area can provide a fundamental understanding of China's local valve industry and contribute to the existing knowledge.

  • Industry 4.0 deployment in the construction industry: a bibliometric
           literature review and UK-based case study
    • Authors: Chris Newman, David Edwards, Igor Martek, Joseph Lai, Wellington Didibhuku Thwala, Iain Rillie
      Abstract: Industry 4.0 is predicted to be a game-changer, revolutionizing commercial and manufacturing practices through improved knowledge utilization and efficiencies. The barriers however, are significant, and the construction industry remains notoriously slow to take up innovations. This study reviews the research work in Industry 4.0 as it relates to construction, and examines a leading UK-based construction firm to ascertain the prognosis for Industry 4.0 roll-out in terms of the impediments and opportunities. A multistage mixed philosophies and methods approach was adopted for this study. First, an interpretivist epistemological lens was used to synthesise extant literature as a means of contextualizing the present study. Second, an empirical case study using a post-positivist stance and inductive reasoning was conducted to explore practitioner acceptance of Industry 4.0 in the UK construction context. Findings from the literature review indicate studies in Industry 4.0 to be a relatively new phenomenon, with developed countries and Germany in particular leading in the field. The range of opportunities are many, but so too are the barriers to enablement. Findings from the case study provide real-world corroboration of the review; practitioners are sanguine about Industry 4.0's potential to reinvigorate the construction industry, but also note that implementation remains curtailed by residual managerial practices dependent on ‘human interaction’. At present, much of the focus of industry practitioners is on the implementation of building information modelling (BIM), often at the expense of other more advanced technologies within Industry 4.0. Research in Industry 4.0 is limited, with the emphasis being on technology application. This paper, by contrast, maps the totality of work carried out so far and presents an assessment of Industry 4.0's progression, potential and degree of uptake within the UK construction industry.

  • Spatial accessibility measures to educational facilities from public
           transit: a case of Indian cities
    • Authors: Pavan Teja Yenisetty, Pankaj Bahadure
      Abstract: The purpose of this paper is to investigate accessibility using spatial assessment techniques, wherein it identifies how educational facilities are connected to public transit (PT) in Indian cities. A new accessibility index is formulated for various ranges of distances which is suitable for Indian cities. This study developed a new method by comparing Euclidean (near) and network distances, uses Google API and other mobile applications for mapping of PT and educational facilities. The study uses built land cover of the city retrieved from Landsat 8 data with a spatial resolution of 30 m. The study attempts to compare the reach to educational facilities from PT in five different cities of India using descriptive statistics, regression analysis, connectivity and detour indices. The results help in identifying local barriers and network issues that influence accessibility from public transit to educational facilities. The study is conducted entirely using spatial techniques, and the data used are collected from various government organizations. The results are useful for improving overall accessibility and developing a framework which can be included in urban development policies.

  • Energy flexibility and shiftable heating power of building components and
           technologies
    • Authors: Tobias Weiss
      Abstract: The paper aims to clarify the relationship between energy flexibility and building components and technologies. It determines the energy flexibility potential of buildings in relation to their physical characteristics and heat supply systems with respect to external boundary conditions. The emphasis of the evaluation is based on the timing and the amount of shiftable and storable thermal loads in buildings under defined indoor thermal comfort conditions. Dynamic building simulation is used to evaluate the potential of selected building characteristics to shift heating loads away from peak demand periods. Insights on the energy flexibility potential of individual technologies are gained by examining the thermal behaviour of single-zone simulation models as different input parameters are varied. For this purpose, parameters such as envelope qualities, construction materials, control systems for heating are modified. The paper provides a comprehensive understanding of the influence of the different building parameters and their variations on their energy shifting potential under “laboratory conditions” with steady boundaries. It suggests that the investigated boundary conditions such as outside temperature, infiltration, envelope quality and user behaviour, which influence the heating load of a building, also influence the resulting potential for energy flexibility. The findings show that the combination of a slowly reacting heat transfer system, such as concrete core activation and a readily available storage mass in the room, and a high insulation standard proved to have a high potential to shift heating loads. In this paper, energy-flexible components were evaluated in a steady-state simulation approach. Outside temperature, solar irradiation and internal loads over the simulation duration were set constant over time to provide laboratory conditions for the potential analysis. On the basis of both duration and performance of the load shifting or storage event, the components were then quantified in a parametric simulation. The determined energy flexibility is directly related to the power of the heating, cooling, hot water and ventilation system, which can be switched on or off. In general, it can be seen that high power (high loads) demand usually can be switched on and off for a short duration, and low power demand usually for a longer duration. The investigated boundary conditions such as outside temperature, infiltration, envelope quality and user behaviour, which influence the load of a building, also influence the resulting potential for energy flexibility. Higher insulation standards, for example, lead to lower loads that can be switched on or off, but increase the duration of the event (flexibility time). So that, in particular, the shiftable load potential is low but results in a long switch-off duration. Furthermore, passive storage potential in buildings like the storage mass inside the room and the type of heat/cooling transfer system can affect the flexibility potential by more than three times. Especially the combination of a high storage mass and a concrete core heat transfer system can significantly increase the flexibility.

  • Thermal comfort prediction of air-conditioned and passively cooled
           
    • Authors: Qi Jie Kwong, Jim Yexin Yang, Oliver Hoon Leh Ling, Rodger Edwards, Jamalunlaili Abdullah
      Abstract: The purpose of this paper is to analyse the thermal environment of two engineering testing centres cooled via different means using computational fluid dynamics (CFD), focussing on the indoor temperature and air movement. This computational technique has been used in the analysis of thermal environment in buildings where the profiles of thermal comfort parameters, such as air temperature and velocity, are studied. A pilot survey was conducted at two engineering testing centres – a passively cooled workshop and an air-conditioned laboratory. Electronic sensors were used in addition to building design documentation to collect the required information for the CFD model–based prediction of air temperature and velocity distribution patterns for the laboratory and workshop. In the models, both laboratory and workshop were presumed to be fully occupied. The predictions were then compared to empirical data that were obtained from field measurements. Operative temperature and predicted mean vote (PMV)–predicted percentage dissatisfied (PPD) indices were calculated in each case in order to predict thermal comfort levels. The simulated results indicated that the mean air temperatures of 21.5°C and 32.4°C in the laboratory and workshop, respectively, were in excess of the recommended thermal comfort ranges specified in MS1525, a local energy efficiency guideline for non-residential buildings. However, air velocities above 0.3 m/s were predicted in the two testing facilities, which would be acceptable to most occupants. Based on the calculated PMV derived from the CFD predictions, the thermal sensation of users of the air-conditioned laboratory was predicted as −1.7 where a “slightly cool” thermal experience would prevail, but machinery operators in the workshop would find their thermal environment too warm with an overall sensation score of 2.4. A comparison of the simulated and empirical results showed that the air temperatures were in good agreement with a percentage of difference below 2%. However, the level of correlation was not replicated for the air velocity results, owing to uncertainties in the selected boundary conditions, which was due to limitations in the measuring instrumentation used. Due to the varying designs, the simulated results of this study are only applicable to laboratory and workshop facilities located in the tropics. The results of this study will enable building services and air-conditioning engineers, especially those who are in charge of the air-conditioning and mechanical ventilation (ACMV) system design and maintenance to have a better understanding of the thermal environment and comfort conditions in the testing facilities, leading to a more effective technical and managerial planning for an optimised thermal comfort management. The method of this work can be extended to the development of CFD models for other testing facilities in educational institutions. The findings of this work are particularly useful for both industry and academia as the indoor environment of real engineering testing facilities were simulated and analysed. Students and staff in the higher educational institutions would benefit from the improved thermal comfort conditions in these facilities. For the time being, CFD studies have been carried out to evaluate thermal comfort conditions in various building spaces. However, the information of thermal comfort in the engineering testing centres, of particular those in the hot–humid region are scantily available. The outcomes of this simulation work showed the usefulness of CFD in assisting the management of such facilities not only in the design of efficient ACMV systems but also in enhancing indoor thermal comfort.

  • Project management processes in the adoption of smart building
           technologies: a systematic review of constraints
    • Authors: Frank Ato Ghansah, De-Graft Owusu-Manu, Joshua Ayarkwa
      Abstract: The necessity for sustainable development and high building performance has led to the adoption of smart building technologies (SBTs) in the construction community. The SBTs adoption has been hindered in many different parts of the world due to several constraints underpinning the project management processes to help adopt SBTs. This paper presents a systematic review of relevant literature on barriers underpinning the project management processes on the adoption of SBTs. This paper presents a systematic review of relevant literature on barriers to technology adoption published in academic peer-reviewed journals and conference papers. The study adopted a systematic review technique on 56 relevant articles and conference papers in relation to barriers to adoption of technology, and barrier frequency was employed to select the most reported barriers. The study revealed the most reported barriers underpinning project management process towards SBTs adoption, which include lengthy approval process for new SBTs, structure and organization of the construction industry, higher cost for smart construction practices and materials, unfamiliarity with smart building technology and technical difficulty during construction process. To both the industry practitioners and policymakers, this review provides a valuable reference during implementation. Also, to the academic scholars on embarking on further empirical studies, the developed checklist of SBTs barriers could be important and useful. This study has contributed to the knowledge of barriers underpinning the project management processes on SBTs adoption by identifying the most reported barriers in literature.

  • Analysis of urban thermal environments based on the perception and
           simulation of the microclimate in the historic city of Tlemcen
    • Authors: Wafa Ghaffour, Mohammed Nabil Ouissi, Marc André Velay Dabat
      Abstract: The preservation of historic urban centres prevents anarchic development of the city and ensures a harmonious evolution of the urban form. It also improves the quality of life in the context of climate and environmental change. Morphological and geometric indicators of the urban fabric are key parameters in the formation of external microclimates. They provide a positive effect on the thermal comfort of pedestrians. The objective of this work is to study the impact of the site morphology on the external microclimate and to understand the relationship between the subjective perception and the objective quantification of the thermal environment. The result of this study has allowed us to propose solutions for the creation of a microclimate favourable to the appropriation of outdoor spaces. The authors finally propose guidelines for the design and rehabilitation of the historic site based on the establishment of links between the site's configuration, microclimatic conditions and users' perceptions. Part of this study included the analysis of the microclimate of the historic “Bab El Hadid” district of the City of Tlemcen, by developing a questionnaire survey and a numerical simulation validated by measurements of the microclimate the authors made on site. To complete this task, the authors applied the Envi-met 4.1 model during the coldest month of the winter and the hottest month of the summer. Urban parameters are represented at different measurement points characterised by a variability of the sky view factor (SVF). The results presented in terms of average expected the predicted mean vote (PMV) voting, solar access and air temperature. They show that thermal conditions are directly related to the SVF, the height/width ratio (H/L) of streets as well as the orientation of urban canyons. The points located in the streets facing North–South, present an acceptable performance. Streets shaded by trees with a canyon aspect ratio of between 1.18 and 1.70 reduce heat stress in outdoor spaces. The PMV models discussed provide information on the most appropriate locations for pedestrians. The authors have proposed urban orientations that could limit unfavourable conditions in outdoor spaces. They are useful for architects and urban planners in the design and rehabilitation of historic centres. In Tlemcen, the microclimate is not taken into account in the design and rehabilitation of urban fabrics. For this specific purpose, the authors want to stress in the research the importance of safeguarding urban heritage through the renewal of the old city and the bioclimatic rehabilitation of its urban spaces.

  • Impediments to the development of the green building market in sub-Saharan
           Africa: the case of Ghana
    • Authors: Michael Addy, Emmanuel Adinyira, James Cofie Danku, Florence Dadzoe
      Abstract: Developing countries in sub-Saharan Africa are faced with significant challenges as the economies continue to emerge. There is a huge infrastructural demand and various efforts to step up supply. Whilst stepping up the supply, the environmental concerns of these supplies require a lot of attention. With the need to reduce the environmental impact of buildings whilst promoting a green infrastructure, various studies have explored the obstacles to green building technology adoption. This study explores the impediments to the development of the green building market in sub-Saharan Africa. Using building consultants as the unit of analysis, this study explores the impediments using a structured survey questionnaire. The study area is Ghana, an emerging country in sub-Saharan Africa. Key impediments to the development of the market is lack of awareness, lack of education and lack of fiscal incentives. The analysis shows that all the variables identified are significant in impeding the growth of the market. The results suggest that within the domain of developing countries, environmental issues may not be of immediate concern as economic issues take centre stage. For sustainability of the environment, it is unequivocal that dissemination of knowledge to key stakeholders be done. Academic institutions and professional bodies have a pivotal role to play in raising awareness of green buildings. Governmental support such as various structures should be put in place to build up the local capacity of firms not only to compete with foreign counterparts but also to ensure innovative delivery of green buildings. The paper presents contextual realities on the green market restrictions within developing countries in sub-Saharan Africa through a deeper understanding of market barriers and recommends pathways for stakeholders.

  • An intelligent system for energy management in smart cities based on big
           data and ontology
    • Authors: Zaoui Sayah, Okba Kazar, Brahim Lejdel, Abdelkader Laouid, Ahmed Ghenabzia
      Abstract: This research paper aims at proposing a framework based on semantic integration in Big Data for saving energy in smart cities. The presented approach highlights the potential opportunities offered by Big Data and ontologies to reduce energy consumption in smart cities. This study provides an overview of semantics in Big Data and reviews various works that investigate energy saving in smart homes and cities. To reach this end, we propose an efficient architecture based on the cooperation between ontology, Big Data, and Multi-Agent Systems. Furthermore, the proposed approach shows the strength of these technologies to reduce energy consumption in smart cities. Through this research, we seek to clarify and explain both the role of Multi-Agent System and ontology paradigms to improve systems interoperability. Indeed, it is useful to develop the proposed architecture based on Big Data. This study highlights the opportunities offered when they are combined together to provide a reliable system for saving energy in smart cities. The significant advancement of contemporary applications (smart cities, social networks, health care, IoT, etc.) requires a vast emergence of Big Data and semantics technologies in these fields. The obtained results provide an improved vision of energy-saving and environmental protection while keeping the inhabitants’ comfort. This work is an efficient contribution that provides more comprehensive solutions to ontology integration in the Big Data environment. We have used all available data to reduce energy consumption, promote the change of inhabitant’s behavior, offer the required comfort, and implement an effective long-term energy policy in a smart and sustainable environment.

  • Emerging paradigm for land records in India
    • Authors: Rashi Gupta, Mona N. Shah, Satya N. Mandal
      Abstract: The purpose of this paper is to establish the importance of land records for urban development. The study focuses on how traditionally land records were managed and presently what are the important parameters impacting the land record management systems in India. The framework adopted for the study was as follows: 1) literature study: aim to study the historical issues, to study global systems across the globe, various government reforms. 2) Present system of land management: to study the administrative, legal, economic issues, problems and potential in the present system. 3) Technology interventions: to study how technology can help to make the system more robust and trustworthy. 4) Conclusion: to study how the recommended technological measures will work and how to implement it in the system. Several pilot interviews were carried out to understand how the present system of land record management works in India, and important parameters were established through the pilot interviews of various stakeholders in the system. The study brings out certain striking facts about the inefficiencies in the system since centuries, which are still being carried forward. Any reforms by the authorities have not been able to solve the issues and reduce the number of litigations because digitisation was only a step forward to replicate the wrong entries of records in digitised format. Thus, a paradigm shift in technology is required to bring a considerable change in the present management system. Various studies worldwide have been done in several countries regarding land records, but all the studies are in piecemeal basis. Very less literature is available on the study that how land records effect large scale urban development projects. This study is an attempt to study impact of land records on urban development and to bring back transparency in the system to reduce the number of litigations on the most important ingredient of built environment, which is land.

  • An assessment of different courtyard configurations in urban communities
           in the United Arab Emirates (UAE)
    • Authors: Hanan M. Taleb, Lama Abumoeilak
      Abstract: This paper aims to find ways to optimise the thermal performance of this courtyard design in current urban communities in hot arid regions. The case study for this research is the Dubai sustainable city residential cluster. After collecting weather data from a site visit, four courtyard configurations were suggested and assessed using ENVI-met simulation analysis software to build a virtual model to represent the base case. This model is used to evaluate the thermal behaviour of outdoor urban spaces. The four courtyard layout scenarios were suggested and tested against the base case model. Scenario one is u-shaped, scenario two is linear, scenario three has central buildings with square courtyards and finally, scenario four has u-shaped buildings with square courtyards. All the courtyard scenarios achieved an adequate level of user satisfaction, and the wind speed and distribution affected the relative humidity of the outdoor areas. The main findings indicate that courtyard scenario four provided the best microclimatic behaviour within the urban community, as the relative humidity dropped from 56.27% to 48% and the temperature was reduced from 43.03 °C to 41.03 °C. The study was focused on Dubai and on urban levels, but the findings can be generalized to cover most of courtiers that have similar climatic and environmental contexts. Architects and urban planners will recognize the potential to reduce energy due to natural ventilation and lower solar radiation. If the findings be applied, this will lead to energy reduction as well as building foot print reduction. This paper contributes to the existing literature by comprehensively reviewing the concept of courtyards in hot climate and in a region of shortage of studies conducted. It will draw future recommendations of how and where to design courtyards within urban communities.

  • Good practices of labor welfare and environmental protection in potato
           crops in Colombia
    • Authors: Albeiro Alberto Aguilar Olivera, Saúl Tomás Salas Suárez
      Abstract: The purpose of this article is to investigate the labor and environmental risks that exist in potato crops in an agricultural area of Colombia and to propose good labor and environmental welfare practices. The study was conducted through the combination of quantitative and qualitative research approaches, applying pragmatic techniques and tools such as direct observation by field journal, questionnaire survey, checklist of working conditions and a specific methodology for the risk assessment. It is identified that the production practices carried out by the cultivators studied are rudimentary, that the agrochemicals used affect the health and safety of the farmers and their families, constituting high-risk products for people and the environment. On the other hand, it is established that the training and qualification of workers is low, they do not use protection elements, or they are not adequate, representing a considerable degree of vulnerability. With the findings of this research it is expected to improve the working conditions of potato growers and sustainability of agricultural processes in the area, whose results will also be very useful for the analysis of the issue throughout the agricultural sector in general, at a national or international level. Contributing in the same way to the fulfillment of the goals of the sustainable development goals.

  • Environment-friendly stimulus-sensitive polyurethanes based on cationic
           aminoglycosides for the controlled release of phytohormones
    • Authors: Manuel Palencia, Mayra Mora, Tulio A. Lerma
      Abstract: Controlled release systems are an efficient alternative for the effective use of agricultural supplies. Among the most versatile controlled release systems are intelligent or stimulus-sensitive polymeric materials, since these materials are multipurpose and adaptable alternatives that offer great adaptability for agricultural applications. The objective of this work was to develop stimulus-sensitive polyurethanes (PUs) based on cationic aminoglycosides (CAG) to be used as an active phase for the manufacture of systems for the controlled release of phytohormones such as naphthalene acetic acid (NAA). The synthesis of stimulus-sensitive PUs was carried out by a polycondensation reaction using CAGs and methylene diphenyl isocyanate (MDI) as precursors. The NAA retention and release experiments were performed at different pH values and ionic forces to include the acidity and salinity of agricultural soils. The results demonstrate that PUs can be obtained from CAG and MDI using the one-step method. The retention of NAA increased as the CAG content increased in the polymer structure, while it is seen that the effect of pH is weak compared to the effect of ionic strength. On the other hand, the release of NAA from cationic PUs can be accomplished by small changes in ionic strength that are mainly affected by the composition of the PU and the pH. The results suggest that, for developed systems, retention and release of NAA is affected by other interaction mechanisms that could probably be related to p-aromatic interactions. Findings are limited to controlled conditions and the expanding of results to extensive crops should be analyzed in next research studies. The practical implications of this study are improving of control for the dosage of phytohormones in stake propagation crops, greenhouse crops, optimization of reseeding operations, among others. The social implication of this study is reduction of pollution by addition of excess of NAA, in consequence, production costs are decreased. Originality and value of this research is the use of PUs based on CAG, and in consequence, the possibility to build novel environment-friendly systems for phytohormone dosage.

  • Determinants of EVs adoption: a study on green behavior of consumers
    • Authors: Ajitabh Dash
      Abstract: This study has a principal objective of exploring and analyzing the factors affecting adoption or acceptance of eco-friendly electric vehicles in India. Primary data were gathered through a predesigned questionnaire from 355 vehicle owners of Delhi using simple random sampling method. Statistical softwares like SPSS and AMOS were used to analyze the primary data collected for the study. Statistical techniques like exploratory factor analysis, confirmatory factor analysis and structural equation modeling were usesd to infer a meaningful conclusion from the investigation. Through this study, a statistically significant relationship between environmental concern, knowledge of EV, subjective norm and attitude toward electric vehicle were investigated. Similarly attitude is responsible for a significant variation in adoption decision. The findings of the present study underscore the requirement for marketers to build up a systematic strategy for easier adoption of electric vehicles in India. On account of this, this study developed a model of potential determinants of adoption decision toward EVs in India, based on statistically significant evidences. This study adds to the body of literature by exploring and testing the factors affecting the adoption of eco-friendly products like electric vehicle that were not emphasized earlier in Indian context and second by growing theoretically consistent operationalization for the marketing of electric vehicles. These upgrades brought about a last model with an unrivaled illustrative power.

      Abstract: In responding to global issues of creating sustainable development, the Indonesian government has enacted regulations (i.e. Ministry of Public Works and Housing No. 05/PRT/M/2015) on the implementation of sustainable construction in infrastructure project execution. The purpose of this paper is to evaluate the means of implementing sustainable principles in the execution of infrastructure projects in Indonesia by the main construction service providers and their partners. A lesson-learned is presented as a source of knowledge to underpin the extensive implementation of sustainable principles in the construction of infrastructure projects leading to an integrated approach in creating a sustainable infrastructure that fulfills the requirements of sustainable development. The method used is questionnaire surveys with Indonesian construction practitioners who are working on building construction, road and bridge construction, water facilities construction and house and settlement construction. From the results, the practices of sustainability principles by construction service providers in infrastructure project execution are imperative from the project procurement phase. The evaluation continues to the phase of construction project execution, which reveals the inconsiderable performance of sustainability indicators due to current constraints on the implementation of sustainability principles. This research looks into the existing gaps between sustainable construction principles and their practical implementation in Indonesian infrastructure projects. This will foster a holistic approach in the practice of undertaking sustainable procurement processes, thus reinforcing project management techniques in the phase of sustainable construction project execution. This also strengthens the interrelated roles and responsibilities of project stakeholders by taking into account principles of safety, balance and the harmony of infrastructure and the environment.

  • Prospects of ocean-based renewable energy for West Africa’s
           sustainable energy future
    • Authors: Ayokunle Adesanya, Sanjay Misra, Rytis Maskeliunas, Robertas Damasevicius
      Abstract: The limited supply of fossil fuels, constant rise in the demand of energy and the importance of reducing greenhouse emissions have brought the adoption of renewable energy sources for generation of electrical power. One of these sources that has the potential to supply the world’s energy needs is the ocean. Currently, ocean in West African region is mostly utilized for the extraction of oil and gas from the continental shelf. However, this resource is depleting, and the adaptation of ocean energy could be of major importance. The purpose of this paper is to discuss the possibilities of ocean-based renewable energy (OBRE) and analyze the economic impact of adapting an ocean energy using a thermal gradient (OTEC) approach for energy generation. The analysis is conducted from the perspective of cost, energy security and environmental protection. This study shows that adapting ocean energy in the West Africa region can significantly produce the energy needed to match the rising energy demands for sustainable development of Nigeria. Although the transition toward using OBRE will incur high capital cost at the initial stage, eventually, it will lead to a cost-effective generation, transmission, environmental improvement and stable energy supply to match demand when compared with the conventional mode of generation in West Africa. This study will be helpful in determining the feasibility, performance, issues and environmental effects related to the generation and transmission of OBRE in the West Africa region. The study will contribute toward analysis of the opportunities for adopting renewable energy sources and increasing energy sustainability for the West Africa coast regions.
