The efficient application of building information modeling (BIM) methodology in the sustainable building design process, known as green BIM, provides ideal leverage to significantly enhance multidiscipline team collaboration. However, the practical execution of green BIM is characterized by issues such as duplication of work, information silos and poor cross-party coordination. Besides, there are limited studies on the specific components that are critical to driving green BIM collaborative design. This study aims to establish the critical components of green BIM collaborative design to enable the multidiscipline team to effectively use diverse software to collaboratively exchange accurate information, thus ensuring informed decision-making in the sustainable building design process.

Data were obtained by using a questionnaire to survey 360 respondents comprising mainly architects and engineers (civil, mechanical and electrical) in Malaysia. Subsequently, data were analyzed via confirmatory factor analysis. Afterward, a measurement model was established and used to test the 11 hypotheses of this study.

A covariance-based structural equation model of the critical components for successful BIM-based sustainable building design collaboration was established.

The research findings will guide the multidisciplinary team to collaboratively exchange accurate information in green BIM practices.

To the best of the authors’ knowledge, this research is the first attempt in the literature to provide a pragmatic approach for practitioners to combine the established critical components of green BIM to collaboratively exchange heterogeneous sustainability criteria and efficiently design buildings with high sustainability performance, particularly in emerging countries like Malaysia.

The Internet of Things-based digital twin (IoT-DT) technologies offer a transformative approach to building retrofitting for reducing operational carbon (ROC) emissions. However, a notable gap exists between the potential and adoption of the two emerging technologies, further exacerbated by the nascent state of research in this domain. This research aims to establish the best practices that innovatively strengthen the identified enablers to decisively tackle challenges, ensuring the efficient implementation of IoT-DT for ROC emissions in buildings.

This study adopted a mixed-method approach. Questionnaire data from 220 multidiscipline professionals were analysed via structural equation modelling analysis, while interview data obtained from 18 stakeholders were analysed using thematic content analysis. The findings were triangulated for cohesive interpretation.

After the analysis of questionnaire data, a structural model was established, depicting the critical challenges (inadequate data security, limited technical expertise and scalability issues) and key enablers (robust data security measures, skill development and government incentives) of implementing IoT-DT for ROC. Sequentially, analysis of in-depth interview data revealed the IoT-based DT best practices (safeguarding data, upskilling and incentivization). Upon triangulating the questionnaire and interview findings, this study explicitly highlights the potential of the established best practices to strategically strengthen enablers, thereby mitigating challenges and ensuring the successful implementation of IoT-based DT for ROC emissions in buildings.

This study provides practical guidance for stakeholders to effectively implement IoT-DT in ROC in buildings and contributes significantly to climate change mitigation.

Green building development practices reduce carbon footprint and promote sustainability in the built environment. To foster green building construction in Malaysia, several strategies and sustainability metrics like the Malaysian Carbon Reduction and Environmental Sustainability Tool (MyCREST) have been established. Yet, the implementation of green office building development in Sarawak still remains low. Therefore, the purpose of this paper is to develop MyCREST Embedded Framework (MEF) for enhancing the adoption of green office building construction in Sarawak.

To achieve the research aim, document analysis of the overarching MyCREST Reference Guide was conducted. Then, questionnaire was used to survey 120 green construction professionals in Kuching, the capital of Sarawak. Afterwards, data from the questionnaire was analyzed using Statistical Package for Social Science software version 22. As a result, the significant strategies for enhancing the adoption of green office building construction in Sarawak were identified, and ranked hierarchically using the Relative Importance Index.

The established significant strategies include: government policies and incentives, sustainable technological practices, defined process for executing green building projects and adequate information for the public. Moreover, this study recommends MyCREST as the suitable Green Building Assessment Tool for developing green office buildings in Sarawak due to its integration of carbon reduction strategies with sustainability indicators.

This study is limited to Kuching; hence future study should be extended to other cities in Sarawak.

Based on the findings, the MEF is developed to enlighten the industry practitioners on the approaches that will elevate green office building development in Sarawak.

The purpose of this paper is to develop a motivation framework that will enhance labour productivity for Iskandar Malaysia (IM) construction projects. The vision of IM development corridor is to become Southern Peninsular Malaysia’s most developed region by the year 2025. IM cannot realise this foresight without effective labour productivity. Previous studies have reported that the labour productivity of IM construction projects was six times lower than the labour productivity of Singapore construction projects, due to lack of motivation among IM labourers, and a shortage of local skilled labour. Therefore, there is a need to study how to motivate IM construction labourers, so as to increase their productivity.

A quantitative research method was used to collect data from IM construction skilled labourers and construction professionals, using two sets of questionnaire. The respondents were selected using a purposive sampling technique. In total, 40 skilled labourers and 50 construction professionals responded to the questionnaire survey, and the data were analysed using Statistical Package for Social Science software (version 22).

The analysis revealed the major factors that motivate labourers participating in IM construction projects. The factors were ranked hierarchically using Relative Importance Index (RII) and the outcome of the ranking indicated that effective management, viable construction practices, financial incentives, continuous training and development, and safe working environment were the most significant motivation strategies that positively influence IM construction labourers.

The study developed and validated a framework that can be used to boost the morale of IM construction labourers, so that their productivity can be increased. Implementation of the established motivation framework will also lead to career progression of IM construction labourers, based on the training elements in the framework. This career prospect will attract local skilled labourers to participate in IM construction projects.

The importance of smartphones in enhancing students learning, research and development is well-established in many published studies. Nevertheless, due to numerous challenges, Nigerian students are yet to reap from the benefits of smartphones in terms of accessing vital information for learning and development. Therefore, this study aims to develop a framework that will enhance Nigerian students’ ability to use smartphones for learning.

The SERVQUAL Theory Framework is adapted to actualize the research aim. Moreover, a qualitative (in-depth interview) research approach was used to interview 60 students from 3 public universities in Nigeria. Purposive sampling technique was used to select the interviewees, and the interview data were analysed using thematic content analysis.

The findings identified the critical constraints that deter Nigerian students from reaping the full potential of smartphones for learning. The constraints are categorized into three groups which include telecommunication companies’ hiccups, such as high cost of internet, poor network services and coverage; government obstacles, such as high tax policies, insufficient electricity supply and lack of basic infrastructure; and university barriers, such as unavailability of Wi-Fi connection for students, lack of equipped university libraries and poor management.

Thus, a holistic Framework for Enhancing Students Smartphones Learning Ability was established to provide fundamental recommendations to the Nigerian Government, telecommunication companies in Nigeria and Nigerian universities to tackle the pressing issues hindering Nigerian students from using their smartphones for learning. This will enhance the smartphone learning experience of Nigerian students.

Green building construction was adopted as a strategy to reduce energy consumption and the overall impact of the built environment on our natural environment. However, in Malaysia, previous studies have reaffirmed that green office buildings consume a substantial amount of energy, compared to their counterparts in Singapore. Moreover, there is still a significant performance gap between predicted energy measurements and actual operational energy consumption of green office buildings in Malaysia, due to occupants’ behavioural discrepancies. Therefore, the purpose of this paper is to develop energy efficiency practices for occupants of green office buildings in Malaysia. The developed practices integrate technology, organisation policy, and occupants’ behavioural strategies, in order to reduce the energy consumption of green office buildings in Malaysia.

To achieve the research goal, a mixed (quantitative and qualitative) research method was used to collect data from the research population. In total, 53 respondents working in a green office building complex in Kuala Lumpur Malaysia were surveyed using a questionnaire. Additionally, three top management staff of the green office building and two Malaysian construction professionals were interviewed. The study adopted convenience sampling technique in selecting the research respondents. The data from the questionnaire were analysed using SPSS software (version 22) while the interview data were analysed via thematic content analysis.

The findings suggest that the integration of technological strategy (use of BIM tools, sustainable building materials, etc.); organisational strategy (develop, implement and evaluate action plans, use of monitor/control systems, etc.); and occupants behavioural strategy (training, incentives, occupants energy efficiency guide, etc.) will critically reduce energy consumption of green office buildings in Malaysia.

Based on the findings, energy efficiency practices are developed to guide occupants in reducing the energy consumption of green office buildings in Malaysia. This strategy will contribute to reducing the performance gap that exists between predicted energy and actual energy use of green office buildings in Malaysia. However, the developed energy efficiency practices need to be validated to ascertain its workability in the green office building context.
