Influencing factors of green building practitioners’ competition perceptions: evidence from China

The concept of green sustainability has driven innovation in green construction technologies (GCTs), fostering heightened competition in the construction market. However, there is limited research on the factors that influence the perceptions of green building practitioners (GBPs) regarding the intense market competition. To address this, based on 407 questionnaires collected in China, this study employs the ordinal logistic regression (ORL) method to investigate the relationship between heterogeneity, psychological capital and industry pressure, and GBPs’ perceptions of market competition intensity. The results reveal that (1) GBPs’ competition perceptions (CPs) are generally high and (2) Individual and occupational differences in GBPs’ CPs are significantly different. Notably, higher education levels correlating to diminished CPs, and managers exhibit greater sensitivity compared to non-managers. (3) Perceived value and company’s environmental responsibility are the most influencing factors that significantly affect GBPs’ CPs. This study offers implications for enhancing GBPs’ understanding of GCTs and industrial competition, thus contributing to improving decision-makers’ strategies for establishing competitive advantages. Additionally, it aids in formulating market competition rules, thereby fostering the transformation of the construction industry.

Analysis of resource utilization competition relationship supporting green low-carbon transformation development of the construction industry

Abstract In order to promote the green and low-carbon transformation development of China’s construction industry and support the optimal allocation of regional resources, this paper constructs a logistic mathematical model of industrial growth and analyzes the resource utilization competition between the construction industry and related industries. The results show that resource utilization competition can lead to the victory of one industry and the exclusion of another, or the stable coexistence of two competing industries, which mainly depends on the competition inhibition effect of the construction industry and related industries, and the relative size of resource load. The conclusion of this study will help the construction industry to innovate the mode and green construction technology, and promote the coordinated development of regional industrial systems.

The Principles and Evaluation of Green Construction of Tunnels in Frigid Plateau Regions

Green construction is an advanced concept and development trend in engineering construction. It is cold and arid in frigid plateau regions in western China, where the ecological environment is vulnerable to engineering constructions and other human activities. Hence, the time and cost for environmental remediation are much larger than in other areas. Based on the principles and category of green construction, this paper discusses the overall and partial relationship between green construction and green construction operation, presents the technical construction process of the green construction of a tunnel, and puts forward the key points of green construction with the construction practice for tunnels in frigid plateau regions as the engineering background. The main contents and results are as follows: (1) The breakthrough points of the research on green construction include five first-level evaluation indicators of savings the land, energy, water resources, materials, and human resources, as well as protection for personnel health and environment, i.e., five savings and two protections. A comprehensive evaluation system suitable for green construction is proposed and established. (2) The paper summarizes the following essential aspects: the fine classification and safety evaluation of surrounding rock, the changes in the seepage field in the construction process, and the establishment of a standardized construction system. (3) A green construction evaluation was conducted on the tunnel of the Yindajihuang Project, and the green evaluation results were obtained. The evaluation results are basically consistent with the actual situation. In addition, intelligent construction technology should be the orientation of green construction for tunnels. The research would be helpful to the implementation of green construction ideas and technologies for tunnels in frigid plateau regions and the persistence of green and sustainable development.

Research on the application of BIM-based green construction management in the whole life cycle of hydraulic engineering

Abstract Taking the construction management of green water conservancy projects combined with BIM as the research background, we analyzed the application of BIM technology in green construction management. The results also showed that the overall trend of green construction management research is on the rise, the research on green construction management at home and abroad is relatively close, and the research directions tend to be intelligent and informative, but there is relatively little research on water conservancy engineering. Combining the current green construction standards of water conservancy projects, the related literature, and the current situation of the application of BIM technology in water conservancy project construction management, the concept of green construction of water conservancy projects and the core requirements of BIM technology for whole-life-cycle green construction are proposed. The new green construction technology was applied in combination with BIM to form a collaborative and scaled multiparty management structure map for the whole process area, build a framework system for green construction management of water conservancy projects, and design a specific implementation process for the application of real-time green construction simulation systems in BIM.

Ecological Wisdom and Inheritance Thinking of the Traditional Village’s Water Resources Management in Taihang Mountains

ABSTRACT In the context of China’s rapid urbanization, the landscape texture and ecosystem of traditional villages are being constructively damaged, especially the water ecosystem responsible for maintaining the sustainable development of villages. It is urgent to explore the green construction technology of traditional villages. However, some traditional villages in Taihang Mountain area exist and develop in the environment of drought and flood, which contains rich ecological water resources management wisdom. Therefore, in this paper, Taihang Mountain is selected as the research area to collect data through literature analysis, field research, and in-depth interviews. This study uses ArcGIS spatial analysis and statistical functions to analyze the acquired data and explore the water resources management practices of traditional villages based on three aspects: safety, function, and spirit. Then it summarizes four key inspirations for contemporary water resources management: “adapt to local conditions, pay equal attention to water use and prevention”; “division of labor and cooperation complement each other”, “low cost, low technology, low maintenance” and “make the best use of materials and compound functions”. These advantageous insights can be offered for the preservation of traditional villages, the enhancement of the living environment, and the management and growth of urban stormwater.

Optimised processes for the production of performance concrete constituents based on agricultural wastes

In most parts of the world urban populations are growing. This inevitably requires resources for construction materials, which is a challenge to achieving global climate goals. Since there is no alternative to concrete as structural material, novel approaches are required to use cement in concrete more efficiently and to use as little Portland cement clinker in the binder for concrete. With novel approaches, Africa can spearhead green urban construction technologies globally, as the continent’s carbon emissions re marginal today in comparison to the rest of the world and the potential to use local resources are enormous. The authors of the paper develop conclusions on how bio-waste can be converted to organic and mineral concrete constituents that have a potential to create rural livelihoods and urban construction materials markets. A three-step solution including a hydrothermal process, a pyrolysis step and a co-fuelling process with brick production in a vertical shaft kiln is suggested to derive organic components, various by-products as well as bricks and pozzolanic cement replacements, respectively.

Analyzing the Impact of Critical Barriers on the Stakeholder’s Adoption Behavior toward Green Building Technologies in Pakistan

The construction industry is becoming a major source of carbon emissions in Pakistan due to the country's rapid urbanization. To slow global warming, it is crucial to evaluate and cut construction's carbon emissions. Despite significant international efforts to encourage the use of green construction technology, which have not yet been extensively embraced because of obstacles, these carbon emissions are continuously rising. In this context, the current research looked at how barriers affected how stakeholders adopted green building technologies (GBTs) in Pakistan. Data were collected through a questionnaire from 349 stakeholders in the construction industry. Partial least square structural equation modeling was used for the empirical study. The main findings revealed that, out of the five types of barriers, innovation-related and economic barriers were found the strongest influencing barriers, followed by socio-cultural and governmental barriers, resource-related and regulation-based barriers towards the stakeholders’ adoption behavior of green building technologies in Pakistan. Based on the research's findings, various policy recommendations were made for the government policy-makers and other concerned stakeholders to ensure the effective deployment of green building technologies in Pakistan.

Does self‐face awareness influence green building project performance?—An empirical evidence from China

AbstractIn the circumstances of “Carbon Peak,” it is imminent to implement green construction technology in the construction industry as it is a major source of CO2 emissions. Nevertheless, little study has been done on the impact of self‐face awareness (SA) on green building project performance (GP). On the basis of a large‐scale questionnaire survey in China and an in‐depth analysis of the four categories (cognition, behavior, satisfaction, and performance), this paper has added an SA dimension, and proposed a new impacting path. Then, based on the improved conceptual model for measuring the impact of green construction behavior on GP, this paper has conducted empirical tests by using a large sample of questionnaire data and partial least square‐structural equation modeling method. The results show that: (1) green construction behavior has a positive impact on GP, and the impact of perceived behavioral control of green construction technology is most significant for promoting green construction in the industry, and SA has a significant positive effect on green construction in the industry; (2) environmental perception and perceived behavioral control for green construction technology play a mediating role; and (3) significant differences indeed exist in the multigroup analysis, and the biggest difference is working experiences in the engineering field. Finally, this paper has proposed corresponding management implications based on the above findings. The main contribution of this study is that this study has developed a new dimension (SA) to the model considering Chinese national and cultural differences, in an attempt to reveal the impact of green construction technology on GP in the Chinese context. In addition, the promotion of green construction (PGC) in the construction industry was also added based on the sustainability perspective, which is the first attempt to explore the role of the PGC.

Multiobjective Optimization Design of Green Building Energy Consumption Based on Inorganic Thermal Insulation Nanomaterials.

In order to solve the problem that building engineering construction needs to consume a lot of energy and cause environmental pollution, which will pose a great pressure on urban resources and environment, this paper proposes that, in building engineering construction, appropriate green construction technology must be selected in combination with the actual situation, so as to effectively reduce the energy consumption of building engineering and improve the use efficiency of building engineering. Firstly, good thermal insulation nanomaterials are selected, which are cost-effective, safe, and nontoxic and has small thermal conductivity, large heat storage coefficient, stable chemical performance, and good construction performance. Secondly, it also needs to be selected according to the actual service life of the building. Because the current evaluation system is mostly aimed at the planning and design stage, and the structure occupies a large part in the building, for example, the impact on the construction period accounts for more than 50% and the impact on the cost accounts for 35%. Therefore, Duan Xiaorong and others established the grey cluster evaluation model of green building structure design based on the triangular whitening weight function. Finally, according to the relevant national regulations, this paper optimizes the design of green buildings based on the basic principles of energy conservation and emission reduction, high quality, and high efficiency.

Experimental Study on UHPC-Based Grouting Materials and Mechanical Performance of Grouted Splice Sleeve Joints

The prefabricated concrete structure is regarded as the main body of the green construction technology, while the joint connection of the prefabricated components is the weak link of force. In addition, the grouting sleeve connection is a widely used connection method in the prefabricated component joints. The effective anchorage of reinforcement is realized by the implementation of a mechanical bite force, friction force and bonding force between reinforcement, grouting material and sleeve inner wall, respectively. Along these lines, in this work, a UHPC-based grouting material was prepared, and its main technical performance was tested. The influence of the grouting mix proportion and anchorage length on the stress performance was thoroughly investigated by carrying out a unidirectional tension test of eight grout-filled splice sleeves. The acquired results show that UHPC grouting containing micro and particles possess high mechanical strength and durability. The incorporation of UHPC grouting containing steel fibers can further improve the compressive and flexural strength. However, its fluidity will be reduced and grouting difficulties will be induced. For that reason, the utilization of UHPC-based grouting material without steel fibers is recommended. The grout-filled splice sleeve joints with UHPC meet also the strength requirements, and the sleeve can be found in the elastic stage in the test, indicating that sleeve joints possess a higher safety margin.
