They should be used to select an economically sustainable solution, with the maximum potential to preserve the cultural and historical value.

Reducing these impacts and optimise the design process is a major priority, and technology needs to be integrated along with the design to allow for better buildings performance. Building Information Modelling (BIM) methodology is one of the technologies that is revolutionising how the supply chain delivers the construction projects, allowing for an overview of the whole life cycle, keeping track of the data along the process, and potentiating more advanced simulations and supported decisions.The tool proposed in this paper aims to integrate different types of sustainability analysis, namely Streamlined Life Cycle Assessment (LCA), Carbon Footprint, Life Cycle Cost (LCC) and Level(s) framework with BIM. This involves defining adequate Product Data Templates (PDT) and a database structure for BIM objects, including the necessary parameters to enable designers to do holistic and dynamic assessments from early design stages to a complete LCA. Also, considering the importance of using BIM to visualise different scenarios, a graphical interface will be developed to show the key sustainability indicators and support decision-making for more sustainable buildings. The results achieved show that technology must be taken to meet Climate most ambition targets and reduce the impact of construction.","PeriodicalId":7150,"journal":{"name":"Acta Polytechnica CTU Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82578430","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}

Incorporating data and feedback from designers and practitioners since early design stages is important to feed a multi-criteria dynamic process with multiple dimensions, which must be assessed under a life cycle perspective. To tackle this issue, this paper introduces a new methodology to support the implementation of tailored refurbishment strategies for increased recovery, reuse and recycling of construction materials. The final objective is to build a methodological framework for sustainable refurbishment design in a BIM environment, which aims to facilitate standardized practices in the construction sector, regarding CE, with a positive impact in the mitigation of global warming and the decarbonization of the building stock. To test the development of this methodology, a case study building in Lisbon, corresponding to a 1919 - 1945 archetype is analysed, making use of its BIM model, where BIM standardization criteria and circularity indicators are discussed, in order to be implemented as a Plugin for Circularity.","PeriodicalId":7150,"journal":{"name":"Acta Polytechnica CTU Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78730939","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}

Thus, there is a pressing need to construct buildings that reduce heat losses, use natural and local materials, exploit renewable sources and ensure high comfort levels with a minimum environmental impact. Reed, considered carbon-neutral and a carbon dioxide sink material, has been used for centuries for diverse uses. Its properties and high availability made it a popular building material, as seen in Portuguese vernacular architecture. Knowing the properties of the reed is a crucial step to ensure successful heritage conservation, optimising these materials, and developing innovative solutions. This paper studies the potential of using giant reed from different Portuguese regions as a thermal insulation material. Giant reed board prototypes (15 x 15 x 5 cm, about 235 kg/m3) were built. Their thermal performance was tested in a hotbox, according to ASTM C1363‑19. The results show that the giant reed harvested on the northern coast of Portugal has better thermal performance than reeds from other regions. However, regardless of the region of the country where the giant reed was harvested, it has a satisfactory thermal resistance (Re ≥ 0.30 (m2.ºC)/W), allowing its use as a thermal insulation material in the buildings.","PeriodicalId":7150,"journal":{"name":"Acta Polytechnica CTU Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76135328","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}

In 2020, the SBC programme published a range of reports focusing on the state of play for circular built environments across specific regions, tied together with a global report. The present focus of the programme is on Africa, Asia and Latin America, where case studies are collected following a common framework.These case studies together with a global survey provide reliable performance data for responsibly sourced building materials in the Global South. The underpinning premise through this process is to support related SDGs across the social, environmental, and economic considerations and enable countries to achieve their targets under the Paris Agreement.

The concept of intelligent building to improve the productivity of the occupants and energy saving was then emerged in 1980s, followed by the focusing of the built environment like green building and sustainable construction in the 1990s. Various metrics were developed by different countries for assessing green building provisions e.g. LEED in a more structure manner. Building resilience has recently become popular for abating the increasing natural disasters. The features of intelligent building, green resilient building and smart city will be illustrated by making references to developments which were designed and project managed by the author.On a more macro scale, with the rapid advancement of ICT in recent years, the concept of smart city has been advocated. The various definitions of smart city would first be depicted. Based on these definitions, the attributes of smart building and the respective features were suggested. The appraisal of the designed provisions of a mixed development project in Southeast Asia was then illustrated with suggestions on further elements to enhance its smart city characteristics.","PeriodicalId":7150,"journal":{"name":"Acta Polytechnica CTU Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91326304","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}
