In this paper, the principle and mechanism of climate adaptation-space interface are established by examining typical building cases in regions characterized by hot summers and warm winters, while factoring in the limitations of previous studies. Finally, employing CFD simulation technology as the primary research methods, this study innovatively proposes three key combination modes for the ‘climate adaptation-space interface.’ Moreover, it obtains the design strategies that can optimize ventilation, shading, and lighting effects simultaneously within these three modes. These design strategies include the following: (1) ‘Component Concave-Convex’ - integrating a single-layer horizontal component with concave-convex window openings; (2) ‘Window-Cavity’ - combining windows with a permeability of 60% and cavities; (3) ‘Components-Windows’ - incorporating folding components with windows.","PeriodicalId":516918,"journal":{"name":"Proceedings of the Institution of Civil Engineers - Engineering Sustainability","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141655537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, the current information system for change management is primarily centralized, relying on external parties, opaque in its information, lacking trustworthiness, and prone to data loss. To overcome these challenges, this paper proposes a blockchain-based information management system for managing change information in EPC general contracting projects. Blockchain is used to automate the review processes for changes, ensuring transparency, decentralization, and resistance to tampering. This proposed framework addresses the security, transparency, tamper-resistance, and reliability shortcomings of conventional methods by harnessing the inherent advantages of blockchain, smart contracts, decentralized IPFS storage, and building information model (BIM) integration. Subsequently, utilizing the Hyperledger Fabric platform, an information management system was developed to store and manage data about modifications. The proposed system was validated using actual change data from EPC general contracting projects, which demonstrated the efficacy of blockchain technology in ensuring the security and authenticity of change data. This advancement enhances the security of change data and augments the efficiency of change management practices in EPC projects.","PeriodicalId":516918,"journal":{"name":"Proceedings of the Institution of Civil Engineers - Engineering Sustainability","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141657447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One way to achieve this is by using innovative building materials. Traditional clay bricks are not eco-friendly due to the depletion of resources, emissions, and waste generated during production. In this study, a new alternative called the Novel Organic Brick (NOB) was produced and evaluated, which was made from recycled construction and demolition sand and red clay as partial replacements for traditional virgin clay. A Life Cycle Assessment (LCA) was conducted to compare the environmental impact of NOBs to that of Kiln Fired Bricks (KFBs). The inventory flows from material sourcing to brick shaping were modelled in SimaPro 8.1 and characterised into impact indicators using the ReCiPe 2016 method. The LCA showed that NOBs can reduce the impact of climate change by 39-56% compared to KFBs, depending on the type and source of recycled sand. This study encourages the construction industry to adopt alternative solutions for greater sustainability by demonstrating the viability of incorporating secondary materials and quantifying environmental performance improvements in India.","PeriodicalId":516918,"journal":{"name":"Proceedings of the Institution of Civil Engineers - Engineering Sustainability","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141668116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explored the intricate interplay between structural performance, economic viability, and environmental impact in the realm of reinforced concrete slabs, with a specific focus on two-way slab-on-beam structures. This study examined the relationship between slab thickness, concrete grade, reinforcement ratios, embodied carbon emissions, and total construction costs. The findings paint a vivid, if not unexpected, picture: thinner slabs are associated with lower embodied carbon emissions and construction costs. However, there is a caveat: thinner slabs may find their place in projects with less demanding structural requirements, whereas thicker slabs, while offering superior structural performance, incur higher costs and environmental impacts. The choice of slab thickness, as this research indicates, is far from a one-size-fits-all decision and necessitates meticulous evaluation of project-specific demands. The data-driven insights presented in this study have the potential to improve construction practices. This research serves as a foundational reference point for the construction industry’s journey towards sustainability, where structures are not merely functional, but also environmentally and economically sustainable.","PeriodicalId":516918,"journal":{"name":"Proceedings of the Institution of Civil Engineers - Engineering Sustainability","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141337391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
