A critical evaluation of these challenges is conducted, alongside strategic pathways to facilitate adoption and maximize impact. Furthermore, the leading countries and seminal contributions in the field are highlighted to guide future research efforts. By addressing knowledge gaps and industry trends, this study provides practical insights for policymakers, researchers, and industry professionals, contributing to the development of innovative frameworks that enhance efficiency, sustainability, and resilience in the era of Industry 5.0.
Against the backdrop of the global energy crisis and climate change, prefabricated buildings, with their high efficiency, energy saving and environmental protection, have become an important direction for the transformation and upgrading of the construction industry. However, despite the promising prospects of Building Information Modeling (BIM) technology and prefabricated buildings in the industry, prefabricated buildings still face many challenges in practical applications, especially in terms of energy efficiency, carbon emission control, and renewable energy integration, which urgently need further optimization. There are still many challenges in the actual application process, and the impact of factors such as government regulatory mechanisms, technical standard formulation, and talent training on the high-quality development of the prefabricated building industry cannot be ignored. Therefore, through literature research, model construction and case analysis, this paper explores the integrated application of BIM and energy management technology in prefabricated buildings, proposes a high-quality development evaluation model based on the Analytical Hierarchy Process (AHP)-fuzzy comprehensive evaluation method, and verifies the effectiveness of the model through the case of prefabricated building projects in Chengdu. The research results show that BIM technology plays an important role in improving the energy efficiency and low-carbon performance of prefabricated buildings. Through the analysis of prefabricated building projects in Chengdu, the feasibility of the model is verified, and strategic measures based on energy optimization are further proposed to promote the prefabricated building industry based on BIM technology to develop in a high-quality, low-carbon, and sustainable direction.
With the growing pursuit of a healthy lifestyle, sports tourism has become an integral part of people's lives. However, sports tourism in China currently accounts for only 5% of the tourism market, while in developed countries, the proportion reaches 25%. This indicates that there is still significant room for growth in China’s sports tourism market. The Belt and Road Initiative proposed by China has had a significant impact on politics, economics, culture, tourism, and other areas. As the gateway to Belt and Road construction, Xinjiang will experience a tremendous boost in its sports tourism industry due to this initiative. This paper employs methods such as literature review, statistical analysis, and SWOT analysis to examine the development of sports tourism in Xinjiang over the past decade under the Belt and Road Initiative, exploring new driving forces for the high-quality development of Xinjiang's sports tourism industry. Based on this, it proposes approaches such as driving new productive forces, multi-dimensional empowerment, adhering to the right principles while innovating, improving quality and efficiency, and promoting integrated development, in order to break through the development bottleneck of sports tourism in Xinjiang.
The construction of simple reservoirs in arid regions helps meet the water demands for agricultural irrigation, industry, and domestic use, while also alleviating local water shortages and related issues. However, environmental concerns associated with reservoir development are becoming more evident. For instance, the stored water is gradually becoming saline. Studies suggest that reducing water evaporation over extended periods can effectively lower the salt concentration in the water. Currently, there is limited research on salt migration in reservoir water when covered with anti-evaporation materials. Given the potential impact of these materials on the water environment and hydrodynamic conditions, this study seeks to examine the spatiotemporal distribution patterns of reservoir mineralization under such covering. To this end, laboratory and field experiments were conducted to analyze the impact of covering the water surface with floating high-density polyethylene spheres to reduce evaporation and its effect on water salinity. These experiments included monitoring water temperature, dissolved oxygen, pH, sediment resuspension, and water conductivity, as well as calculating the contribution of sediment release and evapotranspiration to the increase in salinity concentration within the water column. This study investigates the role of floating high-density polyethylene (HDPE) spheres in reducing reservoir evaporation and mitigating water salinity. Laboratory and field experiments assessed the effects of different coverage levels (0 %-74.98 %) on evaporation rates, sediment resuspension, and water chemistry. The findings indicate that covering 74.98 % of the reservoir surface led to a 28.97 % reduction in salinity (p < 0.05) over one irrigation cycle. Evaporation inhibition varied from 13.56 % to 60.19 %, depending on coverage. However, floating spheres exhibited reduced effectiveness at high wind speeds (>10.7 m/s), highlighting the need for additional containment strategies. Future research should explore long-term durability, ecological impact, and cost-effectiveness of large-scale deployment.
Abstract With the intensification of global climate change, carbon neutrality has become a crucial objective for achieving sustainable development, which critically requires systematic technological innovation and collaborative cooperation between technologies and countries. Through categorization and comprehensive technological assessments, a thorough examination of relevant technologies can furnish a framework to guide emission reduction efforts across various sectors. This review seeks to explore the methods by which various countries achieve carbon neutrality technology systems and pathways, with an in-depth study of the differences between the technological approaches and systems in China, the United States, and European countries. The construction of technology systems in several countries is reviewed, from the composition of the systems to the assessment of technologies that include indicators such as carbon reduction potential. Building upon an analysis of key technological pathways in renewable energy, carbon capture, utilization and storage, energy efficiency improvement, and hydrogen energy across different countries, a systematic evaluation is conducted from three key dimensions—policy formulation, resource endowment, and industrial foundation—to identify the similarities, differences, and driving factors in the construction of carbon neutrality technology systems among nations. Based on the previous work, we conducted a comparative analysis and summary of carbon neutrality pathways across various countries worldwide, systematically reviewing and evaluating carbon neutrality technologies in power generation, industry, transportation, and building sectors. Building upon these findings, the study offers recommendations for coupling diverse technological approaches and for international cooperation. By comparing international experiences and practices, this study provides operational references for countries in formulating technology planning and emission reduction strategies, and also provides an important basis for deepening global carbon neutral cooperation in the future.

The development of thermal insulation protective coatings suitable for constructions and buildings offers a multifaceted approach: it substantially reduces indoor temperatures, enhances residential comfort, decreases air conditioning energy consumption, and conserves energy. Additionally, these coatings provide robust resistance against corrosive substances, thereby significantly prolonging the service life of concrete. In this work, the modification of vacuum ceramic microbeads (VCM) through the polymerization of catechol and hexamethylene diamine to form poly(catecholamine) (PCA) was investigated by FT-IR, XRD, and TEM analysis. Increased levels of incorporation of VCM@PCA further decreased thermal conductivity and increased surface hydrophobicity, while excessive incorporation detrimentally affected the coating's mechanical properties. PDMS/VCM@PCA coating demonstrated exceptional thermal insulation performance, reducing coating temperature by 15.9 °C under simulated sunlight exposure, and in outdoor experiments, the interior temperature of the simulated house with this coating was 4.2 °C lower than the external temperature, highlighting its potential for energy conservation, emission reduction, and building temperature regulation. Additionally, PDMS/VCM@PCA coating provided excellent protection for concrete structures, significantly enhancing abrasion resistance. It also improved the interfacial adhesion between the organic layer and concrete under dry, wet, and 10% NaCl immersion conditions. The addition of VCM@PCA further enhanced resistance to chloride ion penetration, effectively reducing chloride ingress. This thermal insulation protective coating presents a novel strategy for energy conservation, emission reduction, and sustainable development in the civil construction industry.
Three-dimensional printing technology is transforming the construction industry, which is increasingly turning to advanced materials and techniques to meet environmental and economic challenges. This comprehensive literature review evaluated various binder materials, including cement, geopolymers, earthen materials, supplementary cementitious materials, polymers, and biopolymers, with a focus on their environmental impacts and rheological properties. The study revealed an increasing interest in cementitious binders, which deliver essential structural strength and exhibit a wide range of yield stress values (15 to 6500 Pa), influenced by binder type and supplementary materials such as nanoclay. However, the significant CO<sub>2</sub> emissions associated with cement pose major sustainability challenges. As a sustainable alternative, geopolymers demonstrate lower yield stress values (800 to 3000 Pa) while ensuring adequate buildability for vertical printing and reducing environmental impact. These findings underscore the need to adopt sustainable binder matrices to align 3D printing construction practices with global sustainability goals.
Industry 4.0 encompasses a range of ideas, technologies, and procedures that impact engineering education and other fields. Building information modeling (BIM) has become a widely adopted practice in Indonesia's construction industry, prompting polytechnic universities to incorporate BIM skills and concepts into their construction engineering and management degree programs. Nowdays, more than 50 dam construction works occurred in Indonesia from 2014-2024. Monitoring progress regularly is crucial to ensure a construction project's successful completion. This can be done by visually tracking the project's advancement, which enables the identification of any changes or deviations that occur. Accurate measurement data is essential for reliable progress management, as it allows for the prediction of future project success or failure. Image-based object detection is highly beneficial for retrieving site information and monitoring construction progress. To monitor the progress of a construction project, comparisons between the building's as-built and as-planned states are necessary. BIM is employed to establish the intended condition of a building by providing information regarding its geometric characteristics and construction schedule. In this paper, we present a novel method for producing a point cloud that accurately represents the dam building site using photogrammetry. To overcome the limitation of capturing photographs from every possible angle at a construction site, we employ a combination of structure from motion and control points. This approach allows us to generate a scaled point cloud in a standardized coordinate system. The building's as-built and as-planned states are then compared using this point cloud. Structure from Motion (SfM) disparity maps are fused to create dense point clouds, which are then compared to the goal state for updating 4D BIM. This makes it possible to identify missing building components. To validate the presence of building elements, a secondary examination is conducted using the positions in front of and behind the model planes constructed as per the original blueprint. The research paper explores potential approaches and presents empirical results obtained from an actual case study.
In order to achieve sustainable development of the country's economy, it is especially important to promote entrepreneurial activities by developing and implementing strategic state policies. Economic growth and progress is achieved by the development of production. In order to develop an effective entrepreneurial policy, it is necessary to study the definitions of terms.
The understanding of the meaning of "entrepreneurial ecosystem" as a term is diverse and it has undergone changes over time. In order to understand its modern content, it is necessary to analyze the appropriate scientific literature.
In general, entrepreneurship involves the process by which people take advantage of innovative opportunities. The concept of entrepreneurial ecosystem emphasizes that entrepreneurial processes take place among interdependent actors (Stam, 2015: 1761). In short, in this case, the term "ecosystem" should be understood as "economic system" and not as "ecological system". Later, Angelo Cavallo, along with other scientists, focused again on the biological definition of an ecosystem (Cavallo… 2018: 10).
The term "entrepreneurial ecosystem" was first used in 2005-2006 by scholars Prahalad and Cohen to describe conditions where individuals, business representatives, government members, civil society and partners come together to support regional entrepreneurial activities that provide economic prosperity (Cohen, 2006: 3).
The concept of entrepreneurial ecosystems is considered a promising field of research that promotes interconnected entrepreneurial activities (at different levels of analysis) and includes a wide variety of stakeholders and actors in the market (Simatupang... 2015: 394).
The entrepreneurial ecosystem approach starts with the entrepreneurial individual (rather than the firm) but also emphasizes the role of the social and economic context surrounding the entrepreneurial process (Spigel… 2018: 3).
Predecessors of entrepreneurial ecosystem researchers have different emphases in this direction, although common approaches and research conclusions can be seen between them.
Even today, when there is a scientific study of such a complex issue as the entrepreneurial ecosystem, certain problems arise in the research process.
According to various scholars, the concept of entrepreneurial ecosystem should be developed in three directions: first, the concept of entrepreneurial ecosystem and related empirical studies remained only at the theoretical level. Second, little is still known about which interplay of factors at different levels of analysis leads to the desired outcomes of economic development. Third, there is still a substantial, conceptual disagreement about what the desired outcome of an entrepreneurial ecosystem is and how to achieve that outcome (Simatupang... 2015: 389-390).
It should be noted that the entrepreneurial ecosystem model is evolving. Therefore, it is clear that the entrepreneurial ecosystem is a very complex, multi-level "construction". At the regional level, it involves various stakeholders such as non-political decision-makers, government agencies, universities and industry associations.
In the modern period, the entrepreneurial ecosystem is more and more in the focus of politics, but the impact of the ecosystem phenomenon on policy formation is still only theoretical (Autio... 2015: 1). At the same time, entrepreneurship and its role in the world economic order have a special role.
Various scientists talk about the essential role of higher education and universities in the entrepreneurial ecosystem. For example, Eric Lehmann and other scientists identify higher educational institutions as the main component of the entrepreneurial ecosystem, however, they consider university autonomy as a necessary condition for this (Lehmann... 2020: 3). In essence, the term "entrepreneurial-university ecosystem" refers to the idea that universities act as entrepreneurs and contribute to the development of the regional and national economy. An entrepreneurial university involves expanding the traditional role of the university.
In this way, for the formation of the entrepreneurial ecosystem, public and private sector communication is of great importance to promote an effective dialogue between educational, scientific, business and local government representatives.
Based on the above, the concept of entrepreneurial ecosystem can be considered as a promising direction of research. The study of entrepreneurial ecosystems around the world has an important place in the process of policy formation. We definitely believe that practical recommendations should be developed in Georgia in the direction of the development of the entrepreneurial ecosystem according to the priority sectors of the country's economy.
Entrepreneurial universities play an important role in the sustainable development of the country's economy, commercialization of knowledge and activation of other positive processes of entrepreneurial activity. However, we should not forget that for the formation of such universities and the entrepreneurial ecosystem in general, only the desire and the verification of the research results of scientists will not be enough.
Many enabling environments and factors are necessary to ensure this, including: social, cultural, political, economic and regional factors. As complex as the concept of an entrepreneurial ecosystem, including an entrepreneurial university, the readiness of many components is necessary for its effective formation.

Industrial solid wastes, such as ultra-fine fly ash (RUFA) and ground granulated blast-furnace slag (GGBS), hold tremendous potential for recycling due to their abundance and excellent pozzolanic properties. However, red mud (RM), a highly alkaline waste, has not received comprehensive attention in the construction industry. Thus, this study investigates the synergistic effect and geopolymerization mechanism of industrial solid wastes in ternary cementless composites based on RM, RUFA, and GGBS. The experimental program includes macroscopic comparative analyses of water consumption, fluidity, setting time, permeability, and compressive strength of the ternary cementless composite. Additionally, SEM and EDS analyses examine the microscopic morphology and elemental distribution of the composite. The results indicate that RM prolongs the setting time while reducing fluidity and compressive strength. A 30% increase in RM content led to a substantial rise in the initial and final setting time by approximately 191.6% and 164.7%, respectively. In contrast, GGBS enhances the compressive characteristics of the composite systems but shortens the setting time and reduces fluidity. Notably, Group D4 demonstrates the highest compressive strength, reaching an impressive 47.3 MPa. Moreover, the content of GGBS influences the hydration products in the ternary cementless composite. At low GGBS content, the material contains a significant amount of N-A-S-H gels, whereas at high GGBS content, partial N-A-S-H gels are replaced by C-A-S-H gels. These findings significantly enhance our understanding of the synergistic effect and geopolymerization mechanism of RM, RUFA, and GGBS, thereby facilitating the reuse of these three industrial solid wastes.

Geopolymer concrete has been the ideal replacement for Ordinary Portland cement concrete in producing green concrete. The binder in geopolymer concrete is a cementitious paste made from amorphous Aluminosilicate and activated by an Alkaline solution. The geopolymerization process is initiated at elevated temperatures. Thus, the curing requires elevated temperatures. This curing method limits the application of geopolymer concrete in the construction industry. In a geopolymer mix, the presence of Calcium ions allows the formation of Calcium Aluminate Silicate and Calcium Silicate Hydrate gels, allowing ambient temperature curing. Therefore, this study investigates the effect of micro lime on the Sugarcane Bagasse Ash-based geopolymer concrete. The micro lime was added to the geopolymer concrete in 1, 3, 5 and 7% by the Sugarcane Bagasse Ash weight. A mix design was based on a Densified Mix Design Algorithm. The tests carried out included compressive strength and water absorption. Ambient curing of the SCBA-based geopolymer concrete was achieved with 1% of the micro lime. The compressive strength increased with the increase of the micro lime, 10N/mm2 at 1%, to 18.25N/mm2 at 7% micro lime. The ambient temperature-cured geopolymer concrete at 3% micro lime had the lowest water absorption rate.
The building industry is a major consumer of natural resources and a large contributor to environmental degradation, leading to a need to rethink current building practices. Digital fabrication (Dfab) technologies, which transform design and engineering data into physical products, are gaining traction in the Architecture, Engineering and Construction (AEC) industry. This study aimed to evaluate the implications of digital fabrication in the construction industry, by identifying the current Dfab applications and the hindrances that are limiting its implementation. The research questions addressed were why Dfab is essential in the construction sector, the current state-of-the-art of Dfab in the construction industry, and how Dfab is improving the construction industry. Through a systematic literature review, the findings proposed that Dfab can revolutionize the construction sector, enabling freeform architecture, reducing construction costs, cutting material waste, and increasing worker safety. Nevertheless, further research is needed to overcome obstacles such as high costs and the lack of digital skills in the construction industry

As a national pillar industry, the carbon emissions generated by the construction industry have received significant attention. As a large developing country, China has unbalanced regional development and imperfect modern energy infrastructure in some regions, leading to a prominent problem of energy poverty in China. Therefore, this study constructs the index system of energy poverty using panel data of 30 provinces and cities from 2004 to 2016. This article analyzes the influence of energy poverty on carbon intensity of the construction industry and constructs the influence model of carbon intensity of the construction industry. The results show that 1) the carbon intensity of the construction industry increases by 1.683 units per unit increase of energy poverty, showing a positive impact. 2) Energy consumption structure has a mediating effect on the impact of energy poverty on carbon intensity of the construction industry. 3) The technological level plays a moderating role in the main effect of energy poverty and carbon intensity in the construction industry; the degree of marketization plays a moderating role in the indirect effect of energy consumption structure and carbon intensity of the construction industry. These results offered valuable policy recommendations for sustainable industrial growth.

One of the main priorities for the implementation of the tasks set in the Address of the Head of State Nursultan Nazarbayev to the people of Kazakhstan “Kazakhstan’s way - 2050: common goal, common interests, common future” is the transition of traditional industries of Kazakhstan to the production of high value added products.
Structural insulated panel (SIP) in common people is a sandwich panel. Aside from the architectural and aesthetic requirements for building projects, sandwich panels could be called the ideal building material.
The shell of sandwich panels is made with a good and reliable anti-corrosion coating, the insulation material has a low thermal conductivity, minimal moisture absorption, sufficient mechanical strength, and high durability. And the sandwich panel itself is resistant to harmful ultraviolet radiation, atmospheric and mechanical influences. In addition, any communications are easily laid through sandwich panels: drilling or cutting this structure is much easier than reinforced concrete panels.
The development of the oil and gas industry around the world is connected with the development of unconventional fields, such as shale oil, using modern technologies, for example, rotary steerable systems, which allow more accurate and high-quality work on well construction, as well as multi-stage hydraulic fracturing, allowing more efficient extracting of hydrocarbons from the deposits. However, like any mining of minerals, the extraction of hydrocarbon raw materials has a harmful effect on the ecology of the area in which the extraction takes place. This occurs due to the use of a large number of chemical compounds, a small proportion of processing of rocks obtained during drilling, cleaning up territories to create infrastructure for organizing the extraction work of raw materials. The introduction of new fields into development leads to the increase in the level of industrial pollution of the environment. The impact of hydraulic fracturing technology on the environmental situation in the field is considered in the article. The author analyzes the impact of this method of increasing oil development on the environment, the experience of using this technology abroad, as well as government regulation of the use of this technology by producing companies around the world.

Recommendations for the development of the construction industry in certain areas have been developed.
In the traditional civil engineering industry, only abstract theoretical concepts are applied to express complex realistic contents, but this method of information transmission is sometimes very limited for engineering participants, because its expression is not comprehensive and specific and also makes the recipients have difficulty in understanding its information. The rise and development of virtual reality (VR) technology has become a good assistant to overcome this difficulty, providing an extremely effective means for displaying and simulating civil engineering project in real time. This paper introduced the methods and principles of VR platform system and structure dynamic analysis, conducted virtual scene design and three-dimensional modeling of civil engineering project, analyzed the synthetic debugging and simulation roaming of the virtual environment, proposed the engineering model of virtual construction process and planning structure calculation, discussed the realization method of virtual project management and visualization, and finally performed the simulation and its result analysis of panoramic display and planning of civil engineering project based on VR technology. The results show that the VR technology can simulate various environments and activities of civil engineering projects in advance, analyze the rationality of various schemes, and modify their different functional parameters, so it can achieve the simulation optimization of project planning, design, and construction.
The author in the article examined the impact of foreign direct investment on the development of the oil and gas industry in Kazakhstan from the time it gained independence to the present, because attraction of foreign inves-tors contributed to the restoration of oil and gas fields and led to the improvement of technological equipment and social infrastructure. The adoption of relevant regulations and the development of investment policies to determine the further development of oil and gas area is an urgent issue. The object of study has not lost its significance, on the contrary, in the current conditions of the crisis experienced by the world economy and the suspension of economic activity, questions of the development of the oil and gas industry not only in our country, but also in the entire world economy have become more acute and require theoretical rethinking. As a result, it is necessary to continue the study of the problems of directions and volumes of foreign direct investment in this industry.Scientific publications that analyze and predict the further development of the oil industry in modern conditions are becoming extremely necessary and in demand. The development of the industry determines, and in turn, depends on the revitalization of the entire world economy (as a stage of the world economic cycle), and the way out of the world economy from quarantine in the context of the COVID-19 pandemic. World oil prices will depend on this, and hence the prospects for the analyzed scientific problem.The study showed that foreign direct investment contributed to geological exploration, improvement of oil and gas fields, construction of infrastructure in Kazakhstan and solved the problem of oil and gas export to foreign countries. However, the unequal position of national and foreign investors was observed in the oil and gas industry of Kazakhstan, as a result of which the most favorable position for the foreign investors was changed. Also, more than 62% of export earnings were oil and gas condensate. In the event of an outflow of capital from foreign investors, there is a danger to the stability of the economy of Kazakhstan. The results of the study should be taken into account in the development of the state investment plan.
