Abstract
Purpose
This study reveals the green building development path and analyzes the optimal government subsidy equilibrium through evolutionary game theory and numerical simulation. This was done to explore the feasible measures and optimal incentives to achieve higher levels of green building in China.
Design/methodology/approach
First, the practice of green building in China was analyzed, and the specific influencing factors and incentive measures for green building development were extracted. Second, China-specific evolutionary game models were constructed between developers and homebuyers under the market regulation and government incentive mechanism scenarios, and the evolutionary paths were analyzed. Finally, real-case numerical simulations were conducted, subsidy impacts were mainly analyzed and optimal subsidy equilibriums were solved.
Findings
(1) Simultaneously subsidizing developers and homebuyers proved to be the most effective measure to promote the sustainability of green buildings. (2) The sensitivity of developers and homebuyers to subsidies varied across scenarios, and the optimal subsidy level diminished marginally as building greenness and public awareness increased. (3) The optimal subsidy level for developers was intricately tied to the building greenness benchmark. A higher benchmark intensified the developer’s responsiveness to losses, at which point increasing subsidies were justified. Conversely, a reduction in subsidy might have been appropriate when the benchmark was set at a lower level.
Practical implications
The expeditious advancement of green buildings holds paramount importance for the high-quality development of the construction industry. Nevertheless, the pace of green building expansion in China has experienced a recent deceleration. Drawing insights from the practices of green building in China, the exploration of viable strategies and the determination of optimal government subsidies stand as imperative initiatives. These endeavors aim to propel the acceleration of green building proliferation and materialize high-quality development at the earliest juncture possible.
Originality/value
The model is grounded in China’s green building practices, which makes the conclusions drawn more specific. Furthermore, research results provide practical references for governments to formulate green building incentive policies.

Using building information modelling (BIM) technology, a conventional structure in this study was converted into a green building to measure its energy usage and CO2 emissions.
Abstract
Purpose
Using building information modelling (BIM) technology, a conventional structure in this study was converted into a green building to measure its energy usage and CO2 emissions.
Design/methodology/approach
Digital images of the existing building conditions were captured using unmanned aerial vehicle (UAV), and were fed into Meshroom to generate the building’s geometry for 3D parametric model development. The model for the existing conventional building was created and converted to an energy model and exported to gbXML in Autodesk Revit for a whole building analysis which was carried out in the Green Building Studio (GBS). In the GBS, the conventional building was retrofitted into a green building to explore their energy consumption and CO2 emission.
Findings
By comparing the green building model to the conventional building model, the research found that the green building model saved 25% more energy while emitting 46.8% less CO2.
Practical implications
The study concluded that green building reduces energy consumption, thereby reducing the emission of CO2 into the environment. It is recommended that buildings should be simulated at the design stage to know their energy consumption and carbon emission performance before construction.
Social implications
Occupant satisfaction, operation cost and environmental safety are essential for sustainable or green buildings. Green buildings increase the standard of living and enhance indoor air quality.
Originality/value
This investigation aided in a pool of information on how to use BIM methodology to retrofit existing conventional buildings into green buildings, showing how green buildings save the environment as compared to conventional buildings.

Abstract
Purpose
The adoption of green building concepts and practices is rapidly gaining momentum globally due to their tendency to mitigate adverse effects of construction activities on the environment. The purpose of this study is to examine the challenges and benefits of implementing green building development in Nigeria.
Design/methodology/approach
Primary data were collected from questionnaires administered to 122 participants selected using stratified sampling techniques in North-East Nigeria. Semi-structured interviews complemented survey findings with proposed solutions. The quantitative data were analysed using descriptive statistics to identify the benefits and challenges, while thematic analysis was used to identify effective measures to the challenges of green building.
Findings
Results show that “conservation of natural resources”, “reducing maintenance” and “heightened aesthetic” were rated higher as environmental, economic and social benefits, and thus were significant to green building development. The study revealed “economic issues”, “government issues” and “absence of standard assessment system” were the key factors as internal, external and general challenges to green building. Most practical solutions were related broadly to policy, awareness and support as measures to challenges of green building development.
Originality/value
The study is imperative to bridge the knowledge gaps and provide empirical information for green building policy guidelines specific to North-East Nigeria’s built environment sector. The understanding of policy implications will assist in building regulatory and monitoring agencies in developing new internal management policies to inform the public and investors about the effects of green building development.

Abstract
Purpose
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.
Design/methodology/approach
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.
Findings
A covariance-based structural equation model of the critical components for successful BIM-based sustainable building design collaboration was established.
Practical implications
The research findings will guide the multidisciplinary team to collaboratively exchange accurate information in green BIM practices.
Originality/value
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.

Abstract
Purpose
The research on sustainable campus is related to environmental protection and the realization of global sustainable development goals (SDGs). Because the sustainable campus development in China and Japan is carried out around buildings, this paper takes Kitakyushu Science and Research Park as a case to study the characteristics and typical model of sustainable campus in Japan by combined with the characteristics of Chinese sustainable campus.
Design/methodology/approach
This study compares the evaluation standards of green buildings between China and Japan, then compares the assessment results of the same typical green building case and finally summarizes the development mode and main realization path by discussing the implications of green buildings on campus sustainability.
Findings
The results show that (1) the sustainable campus evaluation in Japan mainly pays attention to the indoor environment, energy utilization and environmental problems. (2) Buildings mainly affect the sustainability of the campus in three aspects: construction, transportation and local. (3) The sustainable campus development model of Science and Research Park can be summarized as follows: taking green building as the core; SDGs as the goals; education as the guarantee; and the integration of industry, education and research as the characteristics.
Practical implications
It mainly provides construction experience for other campuses around the world to coordinate the contradictions between campus buildings and the environment based on sustainable principles in their own construction. It proposes a new sustainable campus construction path of “building–region–environment” integrated development.
Originality/value
This study provides theoretical framework for the development of sustainable campuses that includes long-term construction ideas and current technological support greatly improving the operability of practical applications. It not only enriches the sample cases of global sustainable campuses but also provides new ideas and perspectives for the sustainable development research of the overall campus through quantitative evaluation of building and environmental impacts.

Abstract
Purpose
Green buildings have proven to be essential contributors to the sustainability of buildings in the construction industry. However, in developing economies, the rate of green building adoption is slow. Moreover, the factors linked to a relatively slow adoption rarely feature in the literature. This study seeks to bridge the gap by first exploring factors influencing the adoption of green buildings. Second, analysing strategies and preferences determining the adoption of green building principles and lastly, exploring case-based opportunities for their adoption in Tanzania.
Design/methodology/approach
Semi-structured interviews were conducted to collect qualitative data from twelve key informants. The qualitative data were analysed using content analysis.
Findings
The findings indicate that the most influential factors in green building adoption are related to key organizational decisions. Moreover, social and environmental factors are more related to green building adoption than economic factors. In addition, energy and water efficiency are the most commonly adopted sustainability features, while certified materials, recycling and reusing are rarely implemented.
Practical implications
Since green building adoption is still in its infancy, this study informs policymakers, professional bodies, developers, and researchers of the empirically supported factors for green building adoption. The conclusions can be amplified within the sustainability movement.
Originality/value
This study provides an in-depth understanding of the precursors of green building adoption, which is increasingly becoming a paradigm shift in the construction sector. The study is the first to present an in-depth analysis of the real-life factors influencing the adoption of green buildings in Tanzania.

Abstract
Purpose
Green building education, an important aspect of sustainability in higher education, has rapidly expanded across the world. Yet, a bespoke pedagogical model integrating the essential elements of green building knowledge into a university course is lacking. To plug this deficiency, this study aims to develop an innovative pedagogical model that incorporates four types of teaching activities, namely, lecture, virtual reality (VR)-aided site visit, physical site visit and practicum-based project.
Design/methodology/approach
Based on an extensive review of the relevant literature and course materials, a pedagogical model was constructed for application to the teaching and learning activities of a university’s hospitality and real-estate programme. Using a case study approach involving in-depth interviews with green building professionals and a workshop coupled with an online survey on building professionals, the model’s transformative effectiveness was evaluated.
Findings
The study finds that the pedagogical model was able to effectively equip students with the essential green building knowledge pertinent to the different stages of a building life cycle. Concerns about wider applications of the model, including barriers to implementation in other academic programmes and resources for updating the VR platform, were identified.
Originality/value
The VR-aided and project-based pedagogy model is novel and effective in delivering green building education. Future work, particularly expanding the VR platform to cover more green building cases, thereby allowing multiple case studies to be conducted, is recommended for illustrating further contributions and implications of the model.

Abstract
Purpose
This paper improves the evaluation index system of green building operation effect and establishes the evaluation model of green building operation effect. It is expected to promote energy saving and emission reduction and provide a more scientific evaluation method for green building operation effect evaluation.
Design/methodology/approach
First, 20 key evaluation indexes are selected to establish the operation effective evaluation index system. Then, the combined weight method is proposed to determine the weight of each evaluation index. Next, the gray clustering-fuzzy comprehensive evaluation method is used to construct the green building operation effective evaluation model. Finally, the feasibility and validity of the selected model were verified by taking Shenzhen Bay One green building in Shenzhen as an example.
Findings
This paper establishes the evaluation system of green building operational effect, and evaluates green building from the angle of operational effect. Taking Shenzhen Bay One project as an example, the rationality and applicability of the model are verified.
Originality/value
In this paper, for the first time, relevant indexes of user experience are included in the evaluation system of green building operational effect, which makes the evaluation system more perfect. In addition, a more scientific fuzzy gray clustering method is used to evaluate the operational effect of green building, and a new evaluation model is established.

Abstract
Purpose
The purpose of the study is to mainstream the disaster risk reduction (DRR) and disaster resilience measures into the GreenSL® building rating system in Sri Lanka to demonstrate a more holistic approach in achieving sustainability with resilience.
Design/methodology/approach
First, a comprehensive literature review was carried out on green building practices and rating tools, natural hazards and DRR and global and local frameworks. Next, criteria were developed incorporating the disaster resilience aspects through eight expert committee meetings and included the rating tool in three levels. Finally, 11 green-certified buildings from the Green Building Council of Sri Lanka were reevaluated using the new disaster resilient GREENSL® rating system for built environment as a validation for the new tool and to analyze the new certification levels.
Findings
All the green-certified buildings in hazard-prone areas dropped their certification by one level while the buildings in nonhazard-prone areas remained in the certification after being evaluated by the new DRR-incorporated rating system, which recommends the use of new tool for the buildings in hazard-prone areas. But due to the rapid changes in climate and the unpredictable trends of natural hazards, the use of new DRR incorporated GREENSL® rating system for built environment for the certification of buildings is highly endorsed.
Originality/value
This is the first research study based on the GREENSL rating system. And it is the first effort to incorporate DRR aspects to any rating tool in Sri Lanka. The projects that were evaluated for the validation of the new tool are the actual projects which obtained green building certification. Also, it is apparent that this study has gone some way towards enhancing the understanding of blending the sustainability and resilience in rating systems for built environment.
