This research is an on-going thesis project and aims to identify the challenges and expectations of digital technologies’ implementation in off-site construction, and also aims to develop a practical application for promoting one of the promising digital technologies. Mixed research methods are conducted in Chinese off-site construction projects, including a set of semi-structured interviews, observation and site experimentation. The major challenges and expectations of digital technology implementation are presented. Specifically, laser scanning technology is expected to be used to check the installation quality of prefabricated wall panels, and it has been validated as practical and efficient in a case study. Further research will be more focused on validating the robustness of using the laser scanning approach.","PeriodicalId":11904,"journal":{"name":"Environmental Sciences Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86366768","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 research aims to develop and characterize innovative and affordable renewable materials that can meet these low carbon requirements for building envelopes and internal element applications. These materials are geopolymers, which are being researched for fire-resistance, nuclear storage, and cement-based structural applications. Geopolymers are commonly fabricated from high-volume waste materials (e.g., fly ash and blast furnace slag) that are stored in landfill and tailings ponds and have the capacity to facilitate the transition toward a more sustainable and energy-efficient built environment while contributing to the circular economy in the building sector. Two geopolymers, a reference and a prototype, were fabricated and characterized in-lab for their thermal and optical properties to assess their performance for use as building envelope materials. Preliminary results suggest that the prototype has potential for use in green, lightweight building applications. Further optimization of the geopolymers’ thermal and optical performances will open new opportunities for the use of this material in buildings.","PeriodicalId":11904,"journal":{"name":"Environmental Sciences Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79531244","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}

The study aims to explore some salient features of this transition that Luxembourg will face using a theoretical approach. The study was limited to the transportation sector, residential sector, and public dimension. it has been shown how the availability of different contextual factors in Luxembourg will raise the need for new pathways to move towards this transition. The alternative pathways have been argued, too.","PeriodicalId":11904,"journal":{"name":"Environmental Sciences Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89092824","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}

However, there are many risks and barriers that can inhibit the application of EPC. These barriers include uncertainty about building data, lack of quality assurance regarding the post-renovation energy performance, and process complexity. In order to cross these barriers, this paper presents ModSCO. ModSCO is a web application based on a Reduced Order grey-box Model (ROM) able to systematically quantify the energy savings achieved through Energy Conservation Measures (ECMs) utilising the schema of the International Performance Measurement and Verification Protocol (IPMVP). The benefits of utilising ModSCO in terms of accuracy and time savings are demonstrated with a comparison with a whole building energy model developed with IES-VE.","PeriodicalId":11904,"journal":{"name":"Environmental Sciences Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78547119","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}

Renovation of the existing buildings, which are currently responsible for approximately 40% of EU energy consumption and 36% of the greenhouse gas emissions can lead to significant energy savings. This paper presents the EEnvest calculation method for evaluating the financial impacts of technical risks related to energy-efficient renovation of commercial office buildings. The evaluation method aims to increase investors’ confidence and boost investments in the renovation of the existing building. Through a series of Key Performance Indicators (KPI), the technical and financial risks impact is evaluated. The results are strictly connected to building features, climatic conditions, solution sets and mitigation measures specific to the building energy efficiency project.","PeriodicalId":11904,"journal":{"name":"Environmental Sciences Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85395367","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}

However, despite the advantages of more progressive and inclusive city governance, participatory budgeting (PB) often faces challenges to ensure collaboration between different city departments and involved residents. In some cases, residents are unsure about PB models’ transparency, other examples show the way NGOs use the model as a counterforce to central governance and thus local actors lack political and financial support. Moreover, uncertainty and restrictions imposed by the global pandemic in some way also impacted the realization of PB. This research aims to identify stakeholders in the participatory budgeting approach, describing opportunities and challenges of the organizational process and digital technologies as a means of enabling communication and collaboration between actors.","PeriodicalId":11904,"journal":{"name":"Environmental Sciences Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90779756","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}
