The aim of this paper is to investigate, quantify, and rank the relative importance of the decision-making factors contributing to the design of building and urban projects. A survey was conducted to gain an insight of stakeholders’ perceptions as to which are the influencing factors affecting decision-making processes in the design of buildings and places. Ten distinct factors were generated , of which, four were ranked as highly important for all stakeholder types, namely: Potential for Dynamic Operation, Thoroughness, Recency of Tools and Control. This study provides a new means to evaluate performance of decision-making processes, when these are undertaken, by developing and applying a quantitative data-driven, evidence-based methodological framework. The recipients of the findings will be the urban planners, designers, and academics who are interested in improving existing approaches in design and final decision outcomes utilising novel technologies.</p></div>","PeriodicalId":100117,"journal":{"name":"Architecture, Structures and Construction","volume":"2 3","pages":"381 - 401"},"PeriodicalIF":0.0,"publicationDate":"2022-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44150-022-00058-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50033656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This problem is significantly exacerbated for large public buildings with varying occupancy levels. A practical approach to measure occupants’ comfort has been to evaluate the indoor thermal comfort using Fanger’s Predictive Mean Vote (PMV) model, parameterized by the ambient temperature and Relative Humidity (RH). Such an approach is, however, one dimensional and does not consider other possible sources of discomfort like indoor air quality. Interestingly, the ambient temperature and RH, in addition to thermal comfort, also influence the amount of emissions from indoor furnishings, which is a prime source of indoor air quality degradation. Taking this into account, in this paper, we adapt the definition of comfort to include indoor air quality as well. Since occupancy levels, occupants’ activities and outdoor temperature vary with time, one way to achieve desired comfort goals is to continuously adapt the settings of Heating, Ventilation, and Air Conditioning (HVAC) units in buildings. Such a continuous adaptation results in significant energy costs, especially in geographical locations where outdoor temperatures can be significantly higher/lower than desired indoor temperatures. In this context, we propose a location-aware multi-objective optimization model for indoor comfort and energy cost management. We combine conflicting objectives—improving air quality and thermal comforts, and minimizing energy cost—to determine cost-driven, comfort-driven and Pareto optimal solutions using Multi-Objective Genetic Algorithm (MOGA). The proposed model is envisioned to enable building operators to determine suitable temperature and RH as per occupants’ requirement. The solution can be personalized based on the building structure and macro- and micro-location parameters. To ease configuration and customization of our model based on building- and geography-specific settings, we also present a MATLAB-based GUI that operators can leverage to understand the comfort-cost trade-off for buildings.</p></div>","PeriodicalId":100117,"journal":{"name":"Architecture, Structures and Construction","volume":"3 1","pages":"25 - 40"},"PeriodicalIF":0.0,"publicationDate":"2022-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50102665","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 the first stage, cracks are identified and localized using bounding boxes, while in the second stage, the length of cracks and, therefore, the damage severity are determined.

In order to enhance the fire resistance of concrete structures, this paper presents insights into simple and cost-effective solutions by utilizing sacrificial layer(s) of reinforcement. These solutions capitalize on the natural synergy between reinforcement and concrete and have the potential to mitigate fire-induced cracking and the development of fire-induced large deformation, thereby extending the fire resistance of reinforced concrete beams. The validity and applicability of the proposed concepts are highlighted through a highly complex three-dimensional thermo-mechanical nonlinear-based finite element model. This model was utilized in a series of parametric studies to examine critical parameters influencing the fire response of concrete beams reinforced with steel and fiber-reinforced polymer reinforcement. These parameters include sacrificial reinforcement scheme, size, and material type. It was concluded that the use of sacrificial reinforcement could be beneficial for mitigation purposes or as a repair solution for postfire events.</p></div>","PeriodicalId":100117,"journal":{"name":"Architecture, Structures and Construction","volume":"2 2","pages":"311 - 322"},"PeriodicalIF":0.0,"publicationDate":"2022-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50014790","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 gained efficiency is mainly directed towards making standardised linear materials that fulfil the market’s expectation of a continuous flow of identical products with certain constant specifications. The research presented here seeks to question these limitations and provide another approach to the use of wood in construction. The study involves complex geometry handling, architectural design, and material and structural considerations. Trees absorb CO<sub>2</sub> during growth, and as a construction material, wood can function as CO<sub>2</sub> storage, thereby reducing the levels in the atmosphere during the lifetime of the building—and even longer if the building components can be reused. We have seen a significant rise in wood construction over the past few years. This is partly due to growing climate awareness and the increased availability of engineered wood products (EWP). EWPs are reliant on uniform tree production. With growing interest in using wood for construction, an increase in plantation forests is predicted, leading to a lack of biodiversity in the affected areas. The consideration for the general climate expressed through the increased use of wood as a building material may thus appear to be in contrast to the efforts to improve biodiversity. This research seeks to provide an alternative route where non-uniform wood, usually used as firewood, can be used as a construction material. The project demonstrates possibilities that emerge from engaging with the wood as a specific occurrence of a biological entity rather than a standardised material. While historical precedents inspire the research, the project has been developed using digital tools, such as laser scanning, algorithmic design and robotic fabrication. We have developed a unique design-to-production workflow that uses curved natural wood in its original form to enable curved architectural designs. The workflow thereby links the inherent properties of the wood to a distinct mode of expression. The wood is retrieved from a sawmill that collects discarded tree trunks from local forests. The sawlogs are registered with a 3D scanner, and a customised parametric method is used to handle the geometric information and establish a database of the irregular saw logs. A custom-made algorithmic design tool identifies where the sawlogs fit best in a predefined construction design based on the database. Machining data is directly extracted for the subsequent robotic processing. The irregular shape of the material suggests a discrete analysis of the structural properties of each component. A series of destructive physical tests are carried out to indicate the capacity of the structural system and the joint solution.
