ABSTRACT The Increase in natural, unpredictable events these days require a rapid action to mitigate ensuing damage. Emergency architecture is the immediate answer to sudden humanitarian needs. Referring to disaster management phases, architectural design considerations should enhance these phases and prioritizing implementation considerations. To address these challenges, disaster management principles and phases were discussed, and urban planning & shelter design considerations for emergency camps were classified into four principles. These principles include site selection, infrastructure, camps zoning, and shelter design principles, which have a set of factors. These principles and factors are ranked according to their importance from (12) experts opinions and by using the analytical hierarchy process (AHP) as an analysis tool. Then, the study examined the effectiveness of the AHP model by applying it to four emergency camps (previous experiences). Finally, an emergency camp was proposed based on the expert’s evaluation and the lessons learned from the previous experiences.

ABSTRACT Researchers often use daylight and glare analysis to measure visual comfort for daytime inside a built space. However, residential environments include both built and unbuilt spaces. Recently, unbuilt open spaces like courts are gaining equal importance in architectural designs. The literature review revealed very little research on visual comfort analysis in these intermediate open spaces. Therefore, this study proposes a method to analyze visual comfort in identified intermediate open-to-sky courts of clustered residential development. First, by conducting the point-in-time analysis, the study compares field measurements against simulation results to validate the software’s ability to simulate accurate daylight and glare values in these courts. Later, the study analyses visual comfort in identified courts by conducting an annual glare analysis using the calibrated simulation model. The outcome confirms the use of annual and point-in-time glare analysis for visual comfort analysis in courts of residential areas. The results exhibited visually uncomfortable views at the corresponding time. Additionally, simulation experiments highlight the importance of such spaces’ shape, size, and orientation in visual comfort analysis. These outcomes will help future visual comfort research of intermediate open spaces in low to mid-rise residential environments with tropical climatic conditions.

ABSTRACT The main bottleneck during the manufacture of complex geometry thin-walled GFRC structures is the time taken to make the timber or CNC machined moulds for each panel. Complex geometries are comprised of many unique panel forms and the extensive time and high costs of their manufacture often prevents their architectural intent from being fully realised. A novel mould-making process is proposed that uses a state-of-the-art flexible table with computer-controlled actuators to create free-formed geometry, fast-curing, dual-density, polyurethane moulds. This mould-making process was successfully tested by using sprayed GFRC to manufacture 9 different double curved intermediate moulds for a 10 m high GFRC self-supporting, thin-walled hyperbolic shell, with 12 mm thick panels at the base of the structure. The completed structure showcased the effectiveness of the novel mould-making process by reducing the production time from an estimated 100 days to 10 days. The primary outcome was the development and application of a new manufacturing method capable of casting complex geometry thin-walled GFRC panels with good surface quality that was suited to more rapid, cost-effective and automated large-scale production.

ABSTRACT Can skyscrapers survive after COVID-19? Can the idea of integrating vertical farming (VF) into vertical architecture support the environmental, economic, and social issues in the post-pandemic era? Answering these questions is the main objective of this study. Therefore, it explores a) the impact of the pandemic on the built environment, especially skyscrapers; b) the challenges facing the survival of skyscrapers; c) the design parameters and main components of VF; and d) the expected feasibility of integrating VF into vertical architecture to reduce the effects of the pandemic. The research concludes that the skyscraper-integrated vertical farming (SIVF) paradigm can create a closed ecosystem that preserves the environment by a) supporting food security, b) improving indoor environmental quality, c) enhancing psychological and physical health, d) saving energy, e) reducing greenhouse gas emissions and releasing oxygen, and f) supporting the local economy. Consequently, the SIVF paradigm can inaugurate an innovative approach that provides insights into new research trends and discoveries. However, further constraints in the adoption of SIVF should be addressed, and collaborations between researchers and multidisciplinary experts must be created to achieve suitable solutions.

With the need to increase total revenues, airports have begun to use commercial retail. A well-designed airport may provide great service to clients and consumers and increase their satisfaction and in turn their spending behaviours. Since there is suggestive evidence that there might be cultural associations of white, purple or black with di ff erent emotional loadings to these colours across cultures, the present study investigated passengers ’ preferences for architectural design characteristics of an airport in a new cultural setting. Discrete choice modelling was used to measure the passengers ’ preferences for 10 interior design characteristics of the passenger terminal using 3D renderings. Data on 435 passengers were collected at Mehrabad International Airport, which also included passengers ’ emotions. Passengers in the terminal hall preferred a curved and transparent ceiling, material in warm colours, cool lighting, with low width and low height, greenery and without any decorations. When compared to other studies, it may well be that passenger preferences for lighting and certain colour schemes re fl ect geographical or cultural di ff erences. For other interior design characteristics, preferences relating to the shape of the ceiling and the amount of daylight, as well as the presence of greenery, may well be re fl ections of passengers ’ restorative needs.

ABSTRACT This study aims to use modularity to impact various facets of Design for Manufacture and Assembly (DfMA) and explore the relationship between product modularity, process modularity, and DfMA within the context of Offsite Construction (OSC). The study fills this gap through an exploratory single case study by identifying perceptual measures of these three concepts. The study shows the alignment between multi-dimensionality of modularity, such as product modularity and process modularity, enhances the capability of DfMA. From a modularity perspective, the reconfiguration of abstraction, information hiding, and interface is an essential strategy to change the traditional design process. This reconfiguration is to adapt to the new scenarios brought by OSC and digital fabrication technologies and the new design tasks associated with these scenarios. This study has theoretical implications for the modular approach to DfMA and practical implications for those who expect digital fabrication techniques in offsite construction.

ABSTRACT Green buildings (GB) show performance gaps despite a plethora of materials, technologies and stringent certification systems. India is predicted to shape the global energy demand shortly; hence, its recent GB mandate of Energy Conservation Building Code (ECBC) will contribute significantly to the global Agenda 2030. However, its success depends on a holistic relook beyond the myopic design approach focused on energy efficiency. Therefore, a multi-criteria decision support system (DSS) based on the Best-Worst method was developed. It integrates ECBC and BIM-based energy simulation while facilitating maintainability performance prediction in the early phase of design of the GB envelope. The top five options out of 72 common envelope combinations for wall, fenestration and roof materials were chosen for energy performance. The DSS is flexible to accumulate other decision-making criteria as per project-specific requirements. Its efficacy was analysed with a GB located in a warm-humid climatic zone of India. Here, the material availability criterion was also added. The framework provides probing insights and facilitates decision-makers to act appropriately in the early design phase to ensure efficient performance in the long run.

ABSTRACT One of the effective factors on low-income housing (LIH) stigma is the facade features. This study examines the effect of facade features (details, material, window size, balcony existence, and greenery) on three attitudinal aspects including affective appraisal, cognitive judgment, and behavioral tendencies and preferences. By reviewing the literature, facade attributes were extracted and the levels of each were categorized based on LIH cases of Iran. Then, 24 profiles were selected for evaluation using orthogonal design. The experimental method was used with the participation of 70 non-residents in LIH. The results of regression analysis showed that the facade protrusion, balcony existence, greenery, and window size have the highest effect on perceived stigma, respectively; the material with the lowest effect is only in the cognitive aspect and sense of safety in the last rank. The effect of familiarity on the attitudes of outsiders was also investigated and it was found that one’s ‘experience’ affects all aspects of attitudes and preferences and one’s ‘knowledge’ only affects the two emotional and behavioral aspects of attitudes and preferences. These findings can be taken into attention in LIH design and decrease its stigma, as well as in the planning and design of mixed-income communities.

ABSTRACT A shading device is integrated into a building in reducing the indoor solar heat gained. However, the incorporation of a shading device into an opening provides certain effects on indoor natural ventilation. Its performance in enhancing the indoor airflow is still arguable. For this reason, a comprehensive review was executed to identify the effects of a shading device on the natural ventilation of a building. A schematic review process was executed to identify the published articles that were related to the shading devices at the building openings. Subsequently, 25 articles have examined the shading devices at the building openings. The output parameters that were discussed including, the solar heat gained, temperature, energy consumption, daylighting, air quality, airflow, and thermal comfort. The studies agree that the shading device has certain effects on indoor airflow. The effects can be either good or detrimental, depending on the climatic condition, geographical location, building orientation, opening configuration, the shading function, and configuration. It is hoped that this review encourages more investigations of the combined effects of the shading device on solar radiation and natural ventilation. The combined effects are essential in achieving optimum performance of a shading device, which can reduce the solar radiation penetration and enhance the indoor natural ventilation.

ABSTRACT This paper investigates a novel joint method for connecting rectangular hollow section (RHS) members in reticulated shells. It is proposed to overcome the problem of connecting rectangular tubes using the traditional joint (cast steel joint) under dead and snow load. A case study is a structure in the eastern region of Turkey that was built on August 20, 2019. This museum-style structure is 40 meters long and 20 meters wide, with an oval shape. In the middle of the building, five tree-shaped columns were used. ANSYS is used to create a refined 3D solid model of the RHS joint. The moment-rotation results show that the proposed RHS joint (plate steel joint) for connecting rectangular hollow section members can be considered a semi-rigid connection and preferred due to its lower cost and weight. Moreover, the dissipated energy capacity has been raised by approximately 3.22 times when the plate steel type model has been used instead of the cast steel type. The stress ratios indicate that the connection stress in the Cast steel type model is lower than the stress in the Plate steel type model. As a result, the Cast steel type model is determined to be incredibly safe and more rigid than plate steel. Furthermore, since the resulting stress rates are lower than those of S355 steel, both models (cast and plate steel type models) can be used for connecting RHS.

It is proposed to overcome the problem of connecting rectangular tubes using the traditional joint (cast steel joint) under dead and snow load. A case study is a structure in the eastern region of Turkey that was built on August 20, 2019. This museum-style structure is 40 meters long and 20 meters wide, with an oval shape. In the middle of the building, five tree-shaped columns were used. ANSYS is used to create a refined 3D solid model of the RHS joint. The moment-rotation results show that the proposed RHS joint (plate steel joint) for connecting rectangular hollow section members can be considered a semi-rigid connection and preferred due to its lower cost and weight. Moreover, the dissipated energy capacity has been raised by approximately 3.22 times when the plate steel type model has been used instead of the cast steel type. The stress ratios indicate that the connection stress in the Cast steel type model is lower than the stress in the Plate steel type model. As a result, the Cast steel type model is determined to be incredibly safe and more rigid than plate steel. Furthermore, since the resulting stress rates are lower than those of S355 steel, both models (cast and plate steel type models) can be used for connecting RHS.","PeriodicalId":48523,"journal":{"name":"Architectural Engineering and Design Management","volume":"19 1","pages":"550 - 566"},"PeriodicalIF":2.9,"publicationDate":"2022-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42618009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
