The process and product development phase of the research instrument for experiential action research is crucial in the success of the research. Due to time, space and resource limitations, fewer studies have concentrated on this development process. In this respect, research on Augmented Reality (AR) in the Architecture, Engineering and Construction (AEC) industry is no exception. This is more evident in subsurface, urban utilities and infrastructure sector. Furthermore, a limited number of studies on AR/VR have utilized mobile devices as their enabling technologies. This paper sets out to contribute to the state-of-the-art in AR research for urban utilities and infrastructure by outlining a generic procedural workflow to be used for designing AR experiments for experiential research in this area. Given the fact that workflow development research in AR is still limited, this research presents a unique contribution in this area to date.

Research on Augmented Reality (AR) in the Architecture, Engineering and Construction (AEC) industry is still new. As part of a comprehensive study on the application of AR technologies for urban utility infrastructure, this paper sets out to contribute to the state-of-the-art in this area by presenting the results of an industry survey in the UK. The results of the survey conformed, in principles, to majority of findings of the previous research in the field, but also revealed some new or contradictory patterns. Geo-locationing and geo-tagging are still major concerns and have not yet been completely resolved. Relying on global systems does not look like the most reliable option and local systems are required to either replace or jointly work with global systems. With respect to non-AR issues, it is crucial that the quality and content of infrastructure and utilities data are improved and ideally stored centrally in a nationally procured database.

The need for more responsive built environment in the age of climate change has led building professionals to resort to integrated design solutions where a combination of different technologies is utilized to improve what traditionally the tectonics of a building were expected to fulfill rather independently. One of such solutions are Integrated Façade Systems (IFS), which deploy different technologies in or related to building façades to improve building performance. To measure the efficiency of such solutions, three broad categories of methods are in use, namely real, scaled or mock physical models, mathematical models and simulations of which the latter is the most time- and cost-efficient and depending on the platform can provide the most user-friendly method. The flexibility, ease of use and broader coverage of Building Energy Simulation (BES) tools make them a more viable alternative. Developing a benchmark or a base-case model against which the impact of parametric changes of the IFS can be measured is the first step in BES and bares high importance on methodological reliability and validity of the results. This paper uses a specially devised methodology to develop a base-case model for BES of highly- to fully-glazed office buildings in hot and arid climates. BES results of the energy production of the base-case and over 1,600 parametric combinations of the model's system and sub-system levels variables have been used to perform a sensitivity analysis to test the robustness of the results. The results presented in this paper form the last phase of a three-phased analysis of a comprehensive research, designed to provide a full account of how different combinations of a set of variables can and will influence energy performance of highly- to fully-glazed office buildings in hot and arid climates.

The occurrence of crime is widely accepted to be context-specific. Some explanatory theories have focused on social disorder, alluding to the notion that if such disorders are eliminated from society, serious crime would be eradicated. Crime Prevention Through Environmental Design (CPTED) has been adopted to enable the effective use of the built environment to reduce crime. The main aim of this study is to gain further understanding of stakeholders' perceptions of Brixton Town Centre (BTC) in London with reference to CPTED. Using a mixed methodology, a visual audit of CPTED, critical analyses of police crime data, questionnaire surveys and semi-structured interviews were carried out to gauge the effectiveness of key CPTED intervention principles in BTC. It was revealed that since the interventionary measures were introduced in 2011, BTC has experienced a decline in crime rates, whilst there has been an increase for other parts of England and Wales. A positive correlation was found between length of residency and fear of crime. Lighting showed critical in perception of security. Finally, research revealed that despite fallen crime rates, stakeholders agree that further improvement was required. The research concludes with a proposal of further study that will theorize the phenomenon occurring at BTC.

Residential buildings consume a vast amount of energy throughout their whole-life cycles with the subsequent greenhouse gases (GHG) emitted in the atmosphere. This phenomenon will only be exacerbated by projected trends in excessive urbanisation and global population. It is therefore imperative to investigate and quantiatively evaluate the environmental impacts of housing in different regions and contexts in order to enable better and more informed decisions. This is even more urgent in cases where the possibility for urban development is limited or severely constrained. Palestine represents one such areas of the world, and this research focuses on a comparative life cycle assessment (LCA) of contemporary and traditional housing typologies in the region. Primary data has been collected to provide a reliable basis for the LCA, which has been carried out according to the existing international standards. In addition to energy demand and GHG emissions, additional environmental impact categories have been further evaluated to provide a more holistic sustainability analysis. Results—strengthened by an uncertainty analysis—show that environmental impacts, energy use, and global warming potential for contemporary houses are for the most much higher than those for traditional houses. This is mainly due to the high impact of concrete and steel, but further exacerbated by the low impact of limestone as a suitable building material for the region. The results presented in this article signpost an important starting point in investigating the real mitigation potential of specific materials (e.g. limestone and lime mortar) when employed at scale in specific regions of the world. Our findings can also contribute to developmental policies for the region, with an aim of reducing the anthropogenic pressure on the natural environment.

Purpose University students are the future driving forces in and leaders of the architectural, engineering and construction (AEC) industry advancement. Although BIM pedagogical studies have been performed in different institutions, there has not been sufficient research providing a global perspective of BIM education and students’ perceptions toward BIM practice and application following their learning progress. The purpose of this paper is to adopt student samples from Swinburne University of Technology (SUT, Australia), Wenzhou University (WZU, China) and University of Brighton (UK) as three case studies to investigate the BIM practice and application-related perceptions and motivations. Design/methodology/approach Based on the thorough understanding of the BIM pedagogical delivery including teaching contents and assessment methods among the three institutions, a questionnaire survey approach was adopted to collect AEC students’ perceptions of BIM. Within each selected case, statistical analysis was conducted to investigate both the overall sample and subgroup differences regarding students’ opinions on BIM’s functions (e.g. as a 3D visualization tool) and BIM usefulness in various industry professions, their motivation in BIM-related jobs and their perceptions of challenges encountered in BIM practice and application. Multiple factors influencing BIM learners’ perceptions were discussed, such as pedagogical assessment approach, and individual factors (e.g. disciplines). Findings The results showed that students were able to discern the latest industry practices and critical thinking in BIM movements. For example, SUT students perceived more challenges from the government legislation or incentive policies, which was consistent with Australia’s BIM policy movement. WZU students tended to have less positive views on BIM usefulness. The results also indicated fewer differences regarding perceived challenges among students from these three institutions. Originality/value This study contributed to the body of knowledge in managerial BIM by focusing on learners’ perceptions from the perspective of students’ understanding, motivation and individual views of BIM, which were insightful to both BIM educators and employers. By initiating the framework of BIM learning process and its influence factors, the current study serves as a point of reference to continue the future work in strengthening the connection between institutional BIM education and industry practical needs worldwide.

This study adopted a three-step holistic review approach consisting of bibliometric review, scientometric analysis, and in-depth discussion to gain a deeper understanding of the research development in construction safety. Focusing on a total of 513 journal articles published in Scopus, the influential journals, keywords, scholars, and articles in the domain of construction safety were analyzed. For example, simulation and fall from height related topics, although not with the highest occurrence of being studied, had the highest impact in terms of average citation received per year. It was found that research in the recent 10 years have been extended to the developing countries and regions with a more variety of research topics, such as BIM, and data mining, etc. Articles related to applying BIM in safety management received the highest average normalized citation. A follow-up qualitative discussion targeted three main objectives: summarizing mainstream research topics, identifying existing research gaps, and proposing future research directions. Five main categories were aligned, namely safety climate and safety culture, application of information technologies, worker-oriented safety, safety management program, and hazard recognition and risk assessment. Based on the above, a framework and future research directions were proposed which could serve both the academic community and practical fields in multiple themes within construction safety, including: an adaptable safety climate and safety culture model; prototypes, continuous development, and readiness of applying information technologies in safety management; subgroups factors linked to cognitive models of workers’ safety perceptions and behaviors; and artificial intelligence and smart technologies into safety program management.

BIM has been undergoing continuous growth in the global architecture, engineering, and construction (AEC) industry. However, knowledge development within BIM management is lagging behind its implementation. This study initiates a BIM management–based framework involving BIM climate, which is measured by individual BIM practitioners’ perceptions. Subgroup comparison is highlighted in measuring perceptions. Regional variance in BIM climate is addressed in applying the framework by adopting an empirical case study within the context of China’s AEC industry. The case study uses Shanghai and Wenzhou, which represent a BIM-leading metropolitan city and a BIM-developing counterpart, respectively, for the comparative analysis of BIM climate. Based on data collected from a questionnaire survey sent to BIM practitioners from these two cities, it is revealed that Shanghai, as the BIM-leading city in China, has somewhat significant differences in BIM climate compared with Wenzhou. For example, Shanghai BIM practitioners perceive fewer challenges in BIM training, but higher risk in adopting BIM technology. This study contributes to both academic work and practice in BIM based on its initiation of the concept of BIM climate and the case study of BIM-climate comparison. Academically, this holistic study proposes the BIM management–related knowledge framework aiming to fill the knowledge gap in BIM climate and culture, and it could be further applied in subclimates and subcultures within BIM. Practically, the case study provides insights to stakeholders regarding regional variations in BIM climate when promoting BIM practice or establishing BIM guidelines.

Emerging construction practices such as building information modelling (BIM), prefabrication construction, green building, and integrated project delivery methods are gaining momentum in China, with great potential due to the size of its construction market. Through this, the sustainability level of China’s construction industry is expected to be enhanced from the economic, social and environmental perspectives. So far, there has been limited understanding of how BIM, as a digital technology, would affect other contemporary sustainable construction practices from the industry professionals’ point of view. Limited studies have been carried out to study the regional differences of these contemporary sustainable practices in China. This study adopted a questionnaire-based approach targeting industry professionals from three different metropolitan cities (Shanghai, Guangzhou, and Wenzhou).The follow-up comprehensive statistical analysis revealed that with regards to these contemporary sustainable construction practices, survey participants held much varied views on the growth of renovation projects, traditional Design–Bid–Build delivery, and conventional on-site construction methods. These three types were also generally perceived to have weak correlation with BIM application. Regional comparison further conveyed information on differences in perceptions among survey respondents from these three cities. For example, respondents from Wenzhou perceived more positive effects of BIM use in conventional construction projects. This research addressed the inter-correlation among these emerging sustainable construction practices, as well as the regional differences in China’s construction market. The findings provide insights and the big picture for both governmental authorities and industry practitioners on the latest sustainable practices of China’s construction industry. Recommendations are also offered towards improved economic, social and environmental sustainability performance for construction projects in the country.

As an alternative to the traditional structural analysis adopting computer-aided modeling and evaluation, this pedagogical research provides an integrated teaching and learning approach by mapping cognitive domains in a newly launched course, Woodwork Fabrication and Analysis, for second-year students. The course incorporates ancient Chinese woodworking tradition into the integrated learning activities involving engineering graphics, mechanics of materials, hands-on fabrication, and structural modeling/analysis. Comparing the traditional and new courses in terms of their effectiveness in enhancing student learning of structural engineering subjects, both courses are designed to achieve consistent learning outcomes (e.g., to develop structural analysis skills). This study demonstrates student work in engineering drawing and structural analysis reflecting their critical thinking and active learning in the new course. Students from both the traditional and new courses were surveyed about their overall satisfaction with their selected course, their perceptions of the course effectiveness in enhancing civil engineering–related skills, and their expectations of the effect of the course on their further study and work. With the student sample from the traditional course as the control group, the comparative study reveals that the integrated teaching and learning approach in the new course could lead to higher overall student satisfaction and more-positive perceptions of the course effectiveness in enhancing structural analysis–related skills. This pedagogical study will serve as a reference for other civil engineering educators in adopting integrated teaching and learning in lower-year undergraduate education.

Purpose The purpose of this paper is to present a pedagogical practice in the project-based assessment of architectural, engineering and construction (AEC) students’ interdisciplinary building design work adopting BIM. This pedagogical practice emphasizes the impacts of BIM, as the digital collaboration platform, on the cross-disciplinary teamwork design through information sharing. This study also focuses on collecting students’ perceptions of building information modeling (BIM) effects in integrated project design. Challenges in BIM adoption from AEC students’ perspective were identified and discussed, and could spark further research needs. Design/methodology/approach Based on a thorough review of previous pedagogical practices of applying BIM in multiple AEC disciplines, this study adopted a case study of the Solar Decathlon (SD) residential building design as the group project for AEC students to deliver the design work and construction planning. In total 13 different teams within the University of Nottingham Ningbo China, each group consisting of final year undergraduate students with backgrounds in architecture, civil engineering, and architectural environmental engineering, worked to deliver the detailed design of the solar-powered residential house meeting pre-specified project objectives in terms of architectural esthetics, structural integrity, energy efficiency, prefabrication construction techniques and other issues such as budget and scheduling. Each team presented the cross-disciplinary design plan with cost estimate and construction scheduling together within group reports. This pedagogical study collected students’ reflective thinking on how BIM affected their design work, and compared their feedback on BIM to that from AEC industry professionals in previous studies. Findings The case study of the SD building project showed the capacity of BIM in enabling interdisciplinary collaboration through information exchange and in enhancing communication across different AEC fields. More sustainable design options were considered in the early architectural design stages through the cross-disciplinary cooperation between architecture and building services engineering. BIM motivated AEC student teams to have a more comprehensive design and construction plan by considering multiple criteria including energy efficiency, budget, and construction activities. Students’ reflections indicated both positive effects of BIM (e.g. facilitating information sharing) as well as challenges for further BIM implementation, for example, such as some architecture students’ resistance to BIM, and the lack of existing family types in the BIM library, etc. Research limitations/implications Some limitations of the current BIM pedagogy were identified through the student group work. For example, students revealed the problem of interoperability between BIM (i.e. Autodesk Revit) and building energy simulation tools. To further integrate the university education and AEC industry practice, future BIM pedagogical work could recruit professionals and project stakeholders in the adopted case studies, for the purpose of providing professional advice on improving the constructability of the BIM-based design from student work. Practical implications To further integrate the university education and AEC industry practice, future BIM pedagogical work could recruit professionals and project stakeholders in the adopted case study, for the purpose of providing professional advice in improving the constructability of the BIM-based design from student work. Originality/value This work provides insights into the information technology applied in the AEC interdisciplinary pedagogy. Students gained the experience of a project-based collaboration and were equipped with BIM capabilities for future employment within the AEC job market. The integrated design approach was embedded throughout the team project process. Overall, this BIM pedagogical practice emphasized the link between academic activities and real-world industrial practice. The pedagogical experience gained in this BIM course could be expanded to future BIM education and research in other themes such as interoperability of building information exchange among different digital tools.

This study was designed to investigate the recent movement and current stage of China’s construction and demolition (C&D) waste recycling and reuse. Specifically, the research aimed to provide the big picture of recent C&D waste diversion practice in China, as well as to offer insights from Chinese field practitioners’ perceptions towards benefits, challenges, and recommendations of C&D recycling and reuse. This research was conducted based on a review of existing practice and a holistic approach by collecting feedback of professionals from multiple disciplines through a questionnaire-based survey. Totally 77 valid responses were received from 592 questionnaires sent. Both quantitative data and qualitative information implied that China was still at the early stage of recycling C&D wastes. Lack of client demands was identified as one of the main difficulties in C&D waste diversion. The study revealed that engineers and consultants had a more positive perception on promoting industrial training in C&D waste recycling, while construction management professionals held more conservative opinion on it. It was also found that gaining experience in C&D waste recycling and reuse would offer professionals more positive perception on the quality of products containing recycled contents. It was further implied that although governmental supervision had a high impact on China’s current C&D waste management practice, the economic viability should eventually dominate the C&D waste diversion

High solar gain in hot and arid climates causes overheating in summer and increases the demand for air conditioning, energy and carbon footprints of buildings. There are different strategies, tools and solutions to address this problem, but Integrated Façade Systems (IFSs)—façade systems where different technological solutions are integrated to improve performance and to lower the impact of the building—are still an underdeveloped yet a fast-growing field of research. Such systems can reduce solar heat gain, lower air conditioning costs and lessen glare, while maximising the use of natural light and help produce energy if combined with PV technology. Previous research has addressed one or a combination of some of the influential factors on performance of such systems, yet there still is a gap in the state-of-the-art research in comprehensive systematic approach not only to help gauge the impact of alteration of parameters on the IFS performance, but also an approach which can be deployed in other studies where the focus is on façade systems. With a special reference to office buildings in hot and arid climates, this chapter sets out to systematically identify IFS parameters which have potential impacts on energy, lighting, glare and heat gain. Then as a part of a comprehensive ongoing research in this area, this chapter presents a proof of concept to demonstrate the application of such methodology to a parametric study of IFS technology. In doing so, it chooses only one of the parameters indicated in this systematic review and uses building simulation as its core method to investigate the influence and impacts of those variations on performance of IFS. It will indicate how this approach provides high flexibility to adjust or configure any combination of those parameters and to measure, subjectively, how this will result in change in façade performance.

Double Skin Façades (DSFs) are applied in both new and existing buildings, and most of such applications are found in temperate climates. Although research in this area is growing steadily, comparative analyses of DSF applications in different climates are still few and far between. This paper addresses such a gap by means of a comparative thermal comfort analysis of a DSF building model in both tropical and temperate climates. London and Rio de Janeiro have been selected as two representative cities, and three building orientations in each city have been considered; S, SW, and SE, for London in northern hemisphere and N, NW, and NE for Rio in southern hemisphere. Dynamic building energy modelling has been used to determine and assess indoor environmental conditions. While IES VE as the main software tool was utilised, the accuracy and reliability of the results were also cross-checked against a computational fluid dynamic (CFD) software package. Thermal comfort has been assessed through the adaptive comfort approach and results have been analysed and presented in form of comfortable indoor conditions during occupied hours. Results of this study show that the intrinsic flexibility of the DSF can offer indoor comfort for more than half of a year in both climates without any need for mechanical heating/cooling, which contributes significantly to reducing energy demands and cutting CO2 emissions. Additionally, the study shows that the wind force plays a dominant role in driving airstreams in and through the DSF, which highly impacts the overall thermal performance of the buildings. Findings from this research can be useful to academics and practitioners alike, to inform better DSF design and to shed light onto further avenues for DSF research

On average, hot water is responsible for 18% of residential energy consumption and corresponding greenhouse gas (GHG) emissions. Several domestic hot water systems (DHWSs) are commonly used but their life cycle impacts are yet to be established comprehensively. This is due to those impacts varying significantly within the context and the system boundaries of the assessment. This article reports findings from a comparative cradle-to-grave life cycle assessment (LCA) of five DHWSs in the UK context. Primary data acquired from a case study contributed to achieving accurate life cycle inventories that were then modelled in SimaPro through the ecoinvent database. Global Warming Potential (GWP) is the impact assessment method used. Amongst the five types, solar heater with electric backup appears to be the least damaging alternative. The study also reinforces the importance of adopting a cradle-to-grave approach if LCA results are to accurately reflect environmental impacts holistically and lead to better, more informed decisions.

Double Skin Façades (DSFs) are applied in both new and existing buildings, especially in temperate climates. Research in this area is steadily growing; however, there is a lack of conclusive results in available literature about energy performances related to the DSF, thus limiting a better and more informed application of this technology in the Architecture Engineering and Construction (AEC) sector. This article systematically reviews more than 50 articles which have dealt with the energy related performance of DSFs in temperate climates and provides a meta-analysis of the numerical findings published in the studies examined. Energy related figures are presented separately for embodied and operational energy. Specifically, the operational energy end uses taken into account are heating, cooling, lighting, and ventilation. Numerical results in the literature are normalised and expressed in form of percentage of maximum energy reduction/increment compared to a base case (e.g. a single skin case) used as a reference in the corresponding studies. Such an approach is meant to provide a reliable comparison of published figures. Key façade parameters (DSF spatial configurations, cavity width and ventilation), building parameters (orientation and climatic areas) and the methodological approaches used in the reviewed studies were adopted as clustering criteria. Several clustering criteria present extremely spread values, indicating the necessity to further investigate, understand, and attempt to reduce such high discrepancies in operational energy performances. Additionally, and more importantly, almost no information exists on DSFs life cycle energy figures, highlighting an important gap that requires further research

In countries like the UK, the upkeep of existing buildings is where the greatest opportunities for achieving carbon reduction targets lie. Façades are the physical barriers between outdoors and indoors, and their upgrade can arguably be amongst the most effective interventions to improve the existing stock. Double Skin Façades (DSFs) represent a possible solution for low-carbon refurbishment due to their capability to reduce energy consumption, and the related carbon emissions, of the building they are applied to. Although much research exists on maximising the operational energy savings of DSFs, little is known about their life cycle performance. This article addresses such a knowledge gap through a comparative life cycle assessment between DSF refurbishments and an up-to-standard, single-skin alternative. This study adopts a parametric approach where 128 DSF configurations have been analysed through primary data. Energy and carbon (both operational and embodied) are the units assessed in this research. Results show that DSFs are more energy-efficient than single-skin in 98% of the cases, and more carbon-efficient in 85% of the cases. Not only does this study represent the first broad parametric approach to evaluating life cycle energy and carbon of DSFs within its given context, but it also informs environmentally-aware design and application of DSFs.
