The Chinese government vowed to achieve “carbon peak and carbon neutrality” on a global scale in 2020. Since the building sector emits a significant amount of greenhouse gases, achieving the “carbon peak and carbon neutrality” goal will be extremely difficult. Emissions of greenhouse gases can be greatly decreased by developing low-carbon buildings. As more and more new green building materials hit the market, China’s low-carbon construction sector is growing along with the building materials market. This study does a thorough analysis of the literature on the most recent advancements in cost management related to new eco-friendly construction materials in low-carbon economies. The objective is to describe the different dimensions of information green building materials cost management, uncover the underlying themes and sub-themes within these dimensions, identify key research gaps in the current studies, and provide recommendations for future research endeavors. Through the review of the literature, the existing problems in the cost management of new green building materials are revealed. And from the improvement of new green building materials cost management way is elaborated. The conclusion of this paper is that the existing research mainly focuses on the construction of cost management systems and does not systematically study the formation process of material costs, ignoring the consideration of material research and development technology, environmental accounting disclosure and other aspects. Finally, the research project ought to prioritize material research and development, strengthening the cost accounting system, environmental cost disclosure, improving the material management system, and other areas that require in-depth investigation.

Net Zero Energy Buildings (NZEBs) offer a transformative pathway for decarbonizing the built environment by integrating energy-efficient design, renewable energy systems, and smart grid interaction. This review positions NZEBs as critical enablers of low-carbon cities, highlighting their ability to balance annual energy demand through both passive strategies and active technologies. Evidence from the literature shows that advanced envelope materials can reduce heating and cooling loads by up to 18.2%, window retrofits lower thermal loads by 15.5%, and rooftop photovoltaic systems can supply up to 70% of household energy demand in certain regions. The review traces the evolution of NZEBs from early solar integration to contemporary climate-responsive designs aligned with global sustainability frameworks. It also identifies persistent challenges, including high upfront costs, climate-dependent performance variability, and retrofitting difficulties in dense urban contexts. Future directions are suggested in the areas of advanced materials (e.g., aerogels, phase-change composites), urban-scale microgrids for energy sharing, and policy harmonization to strengthen grid resilience. Successful deployment of NZEBs will additionally require interdisciplinary collaboration, standardized international codes, and financial incentives to overcome existing barriers.

Construction organizations in developing nations constantly lag in embracing changes in innovation, environmental sustainability, and safety, amongst others. Their contributions to environmental degradation, resulting in health-related consequences for construction stakeholders, are also alarming. Implementing environmental management tools such as environmental management systems (EMS) is often advocated to address the negative environmental impacts of construction organizations. Construction firms in developed nations have embraced EMS and implemented it to enhance construction business, environmental performance, and construction workers’ health, while similar evidence is not recorded in developing nations. Therefore, this study investigated the barriers to EMS implementation through a survey of construction professionals in the Nigerian construction industry. 106 valid data were analyzed using factor analysis, Cronbach’s alpha test, and fuzzy synthetic evaluation (FSE). The results of the factor analysis revealed four groups of barriers to EMS implementation, which are prioritized in the order of knowledge-related, stakeholders-related, process-related, and cultural-related barriers with FSE. The relationships between the four classes of barriers were determined using interpretive structural modelling (ISM) in which “knowledge-related barriers” are indicated as the core barrier to EMS implementation. To address the barriers to EMS implementation, organizing training, providing the needed resources for environmental education, collaborating with construction stakeholders, providing a reward system, and others were recommended. This study contributes theoretically and practically to environmental-related discourses in the construction industry. Theoretically, utilizing FSE provides an interesting insight that acknowledges the unique challenges of developing nations in the domain. Practically, this study gives an actionable focus for construction stakeholders to domesticate EMS within the local construction environment, thereby improving knowledge of the importance of environmental sustainability and pro-environmental behaviors.

Amid growing global attention to occupational health and safety, the construction industry faces critical challenges associated with engineered stone, which emits high concentrations of respirable crystalline silica during processing and has been linked to severe lung diseases. In response, Australia enacted a comprehensive nationwide ban on engineered stone in July 2024. Drawing on media framing theory, this study analyzes public discourse and sentiment surrounding the ban by examining 7,198 comments collected from Reddit and YouTube. Through Latent Dirichlet Allocation, three dominant themes emerged: health risks and safety concerns, economic impacts and industry transition, and regulatory implementation. Sentiment analysis revealed that 55.5% of the comments expressed negative sentiment, mainly centered on economic concerns, while 21.3% were positive, emphasizing health benefits, and 23.1% were neutral. Economic impact frames predominated among negative comments, whereas health risk frames were more common in positive ones. These findings suggest that future policy communications should more effectively integrate narratives around both health protection and economic transition. This study contributes to the methodological development of sentiment analysis and offers practical insights for policy formulation and implementation.
