Research on the Green Construction Technology of Stilt Houses Based on the Climate Adaptation of Transitional Seasons

Stilt houses are extremely adaptable to terrain and climate. However, current indoor thermal environment research in transitional seasons is not prominent. Therefore, in this research, a typical stilt house in southwest China was chosen as the research object and analyzed by combining Climate Consultant climate analysis software and field measurement data. The results showed that the indoor thermal stability of a stilt house was excellent during the transition season, and the attic had the most obvious climate regulation, with the maximum temperature difference between indoors and outdoors being 9 °C when the outdoor temperature was the highest. The difference between the mean radiant temperature and the average air temperature was only 0.04 °C, and the radiant effect of the enclosure on the interior was small. The indoor relative humidity ranged from 63.2% to 85.1%, showing high relative humidity, but the fluctuation was relatively stable. Stilt floors did not play a significant role in climate regulation during the transition season, and the semi-open space structure was more prone to moisture accumulation when the outdoor humidity was high. Regarding practical application, the climate adaptation strategies of shading, cooling, and dehumidification were applied in the transition season, but dehumidification was ineffective.

BIM-Based Digital Construction Strategies to Evaluate Carbon Emissions in Green Prefabricated Buildings

In this paper, we explore the integration of building information modeling (BIM) technology to assess carbon emissions, emphasizing the unique contributions to smart and sustainable approaches in prefabricated buildings and focusing on the application of digital construction strategies facilitated by BIM to evaluate carbon emissions in green prefabricated buildings, with a detailed case study on C-House at Southeast University, Nanjing, China. The research methodology involved creating a BIM model of C-House in Rhino and collecting data from the operationalization phase. This research work delves into analyzing the structural components, on-site assembling process, and evaluation of carbon emissions by using a BIM-based assessment, as well as the energy load and consumption of prefabricated components, including sustainable PV panels, to enhance building efficiency and sustainability. The findings uncover the life cycle of C-House, which spans seven stages, compared with the five stages of conventional builds. Currently in its third cycle, C-House exhibits significant reductions of 70.57% in carbon emissions during the second cycle and 43.53% in the first one. This highlights the pattern showing that the prolonged reuse of prefabricated buildings leads to decreasing emissions over time. Such results underscore the potential carbon emission reductions and environmental advantages of reusing green prefabricated buildings. Furthermore, this study provides insights into the entire life cycle of the building, from inception to occupation and post-phase performance evaluation. By employing BIM for modeling, simulation, and analysis, we offer practical insights into the application of smart technologies for sustainable construction practices, significantly contributing to the advancement of green and digital construction technologies.

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.

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.
