Green construction for low-carbon cities: a review

Environmental Chemistry Letters, Год журнала: 2023, Номер 21(3), С. 1627 - 1657

Опубликована: Янв. 18, 2023

Abstract The construction industry is a major user of non-renewable energy and contributor to emission greenhouse gases, thus requiring achieve net-zero carbon emissions by 2050. Indeed, activities account for 36% global consumption 39% dioxide emissions. Reducing requires adapted government policies, analysis calculation models, sustainable materials. Here, we review green with focus on history, emissions, life cycle assessment, materials such as biochar, bioplastic, agricultural waste, animal wool, fly ash self-healing concrete. Analysis over the building shows that phase accounts 20–50% total average ratio annual operation 0.62. We present national policy frameworks technology roadmaps from United States America, Japan, China, European Union, highlighting plans neutrality in sector.

A bibliometric analysis of carbon neutrality: Research hotspots and future directions

Heliyon, Год журнала: 2023, Номер 9(8), С. e18763 - e18763

Опубликована: Июль 27, 2023

Global attention has shifted in recent years to climate change and global warming. The international community set the objective of carbon neutrality address crisis. Carbon drawn significant as a crucial step fight against change, with individual nations having established their targets. This paper aims use bibliometric analysis investigate research hotspots trends research, accesses literature through Web Science (WoS) core database undertakes an in-depth examination 909 publications linked around world using Vosviewer Bibliometrix software. According findings, number increased dramatically years. There are also notable differences across countries regions. China US primary drivers leaders developing have relatively little research. Research concentrated on neutrality's practical, technical, policy, economic aspects, well renewable energy sources, conversion technologies, capture storage technologies hotspots. outlines opportunities for advancement future, including how it might be further integrated Artificial intelligence (AI) metaverse, attack difficulties uncertainties faced by post-epidemic rebound. study aids understanding current state field can used guide future studies.

Risk modelling of ESG (environmental, social, and governance), healthcare, and financial sectors

Risk Analysis, Год журнала: 2023, Номер unknown

Climate change poses enormous ecological, socio-economic, health, and financial challenges. A novel extreme value theory is employed in this study to model the risk environmental, social, governance (ESG), healthcare, sectors assess their downside risk, systemic spillover risk. We use a rich set of global daily data exchange-traded funds (ETFs) from 1 July 1999 30 June 2022 case healthcare 2007 ESG sector. find that sector riskiest when we consider tail index, quantile, expected shortfall. However, exhibits highest environment shock form an ETF drop 25% or 50%. The comes China. Finally, have lower (contagion risk) compared Our seeks provide valuable insights for developing sustainable economic, business, strategies. To achieve this, conduct comprehensive assessment ESG, sectors, employing innovative approach modelling response ecological

A Novel Hybrid Methodology to Study the Risk Management of Prefabricated Building Supply Chains: An Outlook for Sustainability

Sustainability, Год журнала: 2022, Номер 15(1), С. 361 - 361

Опубликована: Дек. 26, 2022

The management of the prefabricated building supply chain involves entire process buildings. There are many uncertain factors, and risk factors in any link will affect overall operation chain. In order to achieve “dual carbon” goal as soon possible promote sustainable development chain, it is very important study assembly recognition, prediction, assessment, response. this study, on basis literature research, WBS-RBS (Work Breakdown Structure–Risk Structure) method comprehensively uses working type establish an indicator system for Then, prediction evaluation model neural network BP (Back Propagation) through Python software established predict chains. After verification, was found that accuracy training set test reached 100% 96.6667%. results showed had good effects forecast which provided certain predictions For reference, explore importance results, characteristic algorithm machine learning replacement features further analyzes Finally, based construction project enterprise A, its were carried out, countermeasures targeted risks proposed, we new research assembled provide ideas.

A systematic review of barriers to implementing net zero energy buildings in Australia

Journal of Cleaner Production, Год журнала: 2024, Номер 467, С. 142910 - 142910

Опубликована: Июнь 15, 2024

Building operations use 45% of the total energy in Australia, and Net-Zero Energy Buildings (NZEBs) are instrumental achieving net zero emissions by 2050. However, research reveals that various factors hinder NZEB adoption it is imperative to contextualise barriers, thereby highlighting clear gaps can be addressed enhance implementation Australia. This study presents a systematic literature review bibliometric analysis examine barriers contextualised within Australian building industry. The paper's novelty resides its contextualisation Emergent results reveal most impactful experienced inter-relatedness between their effects on each other. These identified also compared with comparable countries, including UK, China, Italy US. New insight knowledge acquired provide basis for assessing potential solutions main barriers. Findings show lack knowledge, climate issues, cost addition government policy factors, considered primary encountered industry, hindering achievement NZEBs. It future studies initiatives counteract these impacts realise better context.

Purpose While operational carbon (OC) emission reduction strategies have received substantial attention in past literature, very few studies focused on embodied (EC) the construction industry. Therefore, this study aims at undertaking a scientometric review of to mitigate EC emissions Design/methodology/approach Scopus search engine was used for articles. VOSViewer software analysis using science mapping approach. Using total 151 documents, keywords, authors, papers and their sources were analysed. Furthermore, undertaken comprising co-occurrence documents source author co-citation analysis. Findings The significant identified were: offsite manufacturing/use prefabricated elements, decarbonisation energy grid, enhanced policies regulations by governments, sector regulations, guidelines increased use low materials reuse recovery materials. Practical implications This identifies practical that contribute emissions. Originality/value is contributes industry’s agenda greenhouse gas
