Human factors and ergonomic principles in building design for life and work activities: an applied methodology

Ergonomic approach is aimed at optimizing human interactions with systems, in order to make human activities more efficient, safe, comfortable and satisfying. Built environment influences people’s everyday life because all human activities are executed in a built space. In this framework, architectural design can be enhanced by the consideration of human factors perspective, because it gives the cultural and practical references to envisage how technical solutions can fit the environmental needs derived from people’s life and work activities they perform. Since the main objectives of sustainable design are to reduce, or completely avoid, depletion of critical natural resources and raw materials; prevent environmental degradation caused by facilities and infrastructure throughout their life cycle; create built environments that are livable, comfortable, safe, and productive, a broader consideration of the role of human factor has to be taken into account to enhance design process of sustainable buildings. Several studies evidence that to reach sustainable goals of buildings, particularly referred to energy and resources use and optimization, unexpected disadvantages for final users may occur. The paper shows recurring human side effects of building solutions and elements mainly adopted to address green strategy and technologies, in order to support building design to create working and living spaces actually fitting, in the same time, sustainable performance of buildings and needs of inhabitants.

Applications of Artificial Intelligence AI are increasingly significant for designers across various fields, with a particular emphasis on architectural design. These applications offer support by providing relevant data and suggesting diverse design ideas. This study explores the applications of AI in the architectural computational design process, employing a mixed-review approach that combines bibliometric analysis and systematic review. The objective is to study the uncovered research area figured from the review by clarifying the primary functions of AI in all architectural design stages, as well as the associated opportunities and challenges . This study examines the application scale, methodologies, and tools of AI in architectural design. Then, it conducts a comprehensive survey of commonly used AI tools, analyzing and comparing them based on phase classification, deployment classification, scale of application, and their integration with BIM, VR, and parametric design Additionally, the study proposes an AI-powered Architectural Computational Design Process (AI-ACD), a workflow designed to aid architects in effectively incorporating AI technologies into various stages of computational architectural design processes. Afterwords the study also introduces a classification of commonly used AI tools and maps them to specific design tasks within the (AI-ACD) workflow. Multiple design scenarios and a set of core integration principles are proposed to demonstrate how AI engagement can be tailored to different levels of use and project contexts. Finally, the study presents a matrix that maps each core integration principle to the five key design stages The study demonstrates how AI-ACD, an AI-assisted workflow, enhances the architectural design process through visualization, data analysis, and optimization tools, adaptable to architecture, urban design, and heritage, ultimately boosting creativity, efficiency, and design quality.

IntroductionThe construction industry is one of the world’s largest carbon emitters, accounting for around 40% of total emissions. Therefore, reducing carbon emissions from the construction sector is critical to global climate change mitigation. However, traditional architectural design methods have some limitations, such as difficulty in considering complex interaction relationships and a large amount of architectural data, so machine learning can assist architectural design in improving design efficiency and reducing carbon emissions.MethodsThis study aims to reduce carbon emissions in the architectural design by using a Transformer with a cross-attention mechanism model. We aim to use machine learning methods to generate optimized building designs that reduce carbon emissions during their use and construction. We train the model on the building design dataset and its associated carbon emissions dataset and use a cross-attention mechanism to let the model focus on different aspects of the building design to achieve the desired outcome. We also use predictive modelling to predict energy consumption and carbon emissions to help architects make more sustainable decisions.Results and discussionExperimental results demonstrate that our model can generate optimized building designs to reduce carbon emissions during their use and construction. Our model can also predict a building’s energy consumption and carbon emissions, helping architects make more sustainable decisions. Using Transformers with cross-attention mechanism models to reduce carbon emissions in the building design process can contribute to climate change mitigation. This approach could help architects better account for carbon emissions and energy consumption and produce more sustainable building designs. In addition, the method can also guide future building design and decision-making by predicting building energy consumption and carbon emissions.

Recently, digital fabrication techniques have captured the attention of many architects and makers due to their ability to challenge traditional construction techniques and complex forms that were hard to apply in the past. Digital fabrication has bridged the gap between the architectural design and construction processes by creating a direct digital link to the appropriate fabrication machines. Nevertheless, integrating digital fabrication techniques in the architectural design processes is still a major challenge to creating a culture of digital building all over the world. In this regard, this paper has arranged 10 key questions and their answers with a particular focus on how to integrate digital fabrication techniques into the architectural design process. It provides an overview of digital fabrication concepts and processes, computer software, material selection, the most popular digital fabrication techniques and their architectural applications such as free-form geometries, façades design, buildings, bridges, pavilions as well as structures like columns, walls, and slabs, along with the most significant challenges and opportunities facing the widespread use of these techniques in architecture. In an effort to identify new research trends, this paper concludes by discussing the state of the art in architecture-related digital fabrication research and research potential gaps, which will be beneficial to further research and scientific investigations in this field. Hence, a conceptual framework is suggested as a guideline for numerous architects, fabricators, and researchers to follow for integrating digital fabrication techniques into the architectural design process in order to take advantage of this strategy at scale.

Purpose The present study aims to formulate a framework acting as a design methodology for non-expert architects in circular economy (CE). This design methodology strives to define the circular architectural design process by identifying architectural circular design strategies, supporting tools, knowledgebases required and changing roles of architects. Such a framework may facilitate wider dissemination of circular design practices in architecture. Design/methodology/approach The design of the research methodology employs a three-phase strategy combining qualitative and quantitative methods. It captures knowledge from both literature and expert architects in CE. The first phase follows a qualitative strategy to capture explicit knowledge from literature. The second one follows an inductive approach through a survey to capture tacit knowledge of circular design from experts. The third one uses gamification, creating user-friendly, haptic and playful tools, namely, game board, wheel, cards, calculator and dynamic sunburst, to stimulate design thinking. Findings The study reveals 20 circular design strategies, translating them into 92 design actions that are applicable at early architecture design phases. It highlights artificial intelligence and digital market platforms as the easiest applicable tools in architecture circular design. This study reveals design for multiple use cycles as the most important required skill in circular design, while circularity consultation is the most vital new role for architects. The results confirm the reciprocating characteristic of the circular design process. According to circularity assessment, the “design with right resources” strategy has the highest circular impact, emphasizing using existing assets as the most impactful design action. Originality/value This paper presents a multi-dimensional methodological framework, depicting the relation between circular design strategies, supporting tools and required competencies for architects to be circular designers. This is coupled with a holistic circularity assessment from early stages, unlike existing stand-alone indicators, through the developed circularity calculator. The proposed design methodology acts as an accelerator model through gamification that features a step-by-step design process board, design strategies wheel, design actions cards, circularity calculator and dynamic class sunburst. This paper fulfills a geographical gap in circular built environment research by including experts from Africa with specific emphasis on Egypt.

The nexus between ergonomic (human factor) and housing design and occupants’ satisfaction is essential for housing quality. The need for housing that is comfortable, functional, safe and decent cannot be over emphasized. These can be realized with the application of ergonomic / human factor principles in housing design. This paper examined the critical issues that promote the application of ergonomic/ human factor principles in housing design. They include the following: Comfort and Efficiency in housing design, Users’ participation in building designs; the role of ergonomic / human factors in architectural design and the relationship between ergonomic / human factors in sustainable housing designs. The paper made use of library research method, which involved critical review of related literature relevant to the study. The articles were analyzed descriptively. Suggestions that would help in the realization of human factors in housing designs and construction were made. The paper concludes that occupants’ satisfaction could be increased and enhanced when architects and other professionals in the built environment give adequate consideration to ergonomic / human factor principles in their building designs. Keywords: Ergonomics, Human factors, housing design, Occupants’ Satisfaction and housing quality. DOI : 10.7176/JEES/9-4-09 Publication date : April 30 th 2019

In this study, a design methodology based on prototyping is proposed. This design methodology is intended to enhance the functionality of the test, differentiating it from the prototyping that is being conducted in conventional architectural design projects. The objective of this study is to explore reference cases that enable designers to maximize the utilization of both digital models and physical models that have been currently used in architectural designs. Also, it is to explore the complementary roles and effects of digital models and physical models. Smart Building Envelopes (SBEs) are one of challenging topics in architectural design and requires innovative design process included tests and risk management. A conceptual prototyping-based model considering the topic is applied to the design studio (education environment in university). Designing SBEs is not difficult to conceive ideas, but it is impossible to “implement” using the conventional design method. Implementing SBEs requires to strengthen validities and improve responsibilities of ideas in the stages of architectural designs, with cutting-edge technologies and smart materials. The design methodology enables designers (represented by students) to apply materials and manufacturing methods using digital models (parametric design, simulation, BIM) and physical models, rather than representing vanity images that are considered simple science fiction.

The aim of this paper is to move established positions in architectural design by discussing a more refined user perspective. The motivation is threefold. Firstly, fields like environmental psychology and cognitive science for architecture have in recent years brought novel insights on the embodied nature of human spatial experience, and the extensive effects of the built environment on people’s psychosomatic health and behaviour that are not well-captured by existing building standardization systems. Secondly, while the fast growing trends of user-centred and research-based design in architecture have showed that users’ experience is a valuable source of design knowledge, the methods for incorporating this wealth of new insights in the architectural design process are still underdeveloped. Finally, the example of the newly built psychiatric department in Aabenraa, Denmark, whose interior, despite an international architectural award in 2016, had to be re-designed one year after construction due to poor understanding of the users, indicates existing discrepancies in the current approaches to translating research information in user-centred design. To address these issues, we discuss the experiences from a new masters’ course in ‘Architecture, Health, and Well-being’ and propose that user-centred methods like ‘personas’ and ‘scenarios’ used in IT, marketing, and product development also have a potential to develop more in-depth research-informed user perspectives. As well as, to help students envision and strengthen the architectural quality of the programming and building design throughout the architectural design process, by supporting a ‘design empathic’ understanding and immersion in user perspectives.

Purpose: To review and analyze the research status of the application of generative adversarial networks (GANs) in the field of architecture design. Methods: This study followed the latest PRISMA guidelines and systematically collected relevant research literature from domestic and international sources. In-depth analysis was conducted on 95 representative Chinese and English language articles. During the analysis process, three dimensions of intelligent architectural generation methods were comprehensively and deeply explored: the data application scale, algorithm type, and architectural design process. Results: (1) GANs have been applied to various processes in architectural design practice, from design generation, development, and evaluation to final solution expression; (2) GANs can be applied at different architectural scales, ranging from large-scale complex functional buildings to refined layout designs of residential units; (3) the appearance of GANs enables designers to quickly present design results at various stages, greatly improving work efficiency; and (4) at present, GANs also have many shortcomings, mainly reflected in the accuracy of the data and the usability of tools. Conclusion: Improvements in computer performance and the enrichment of data resources have promoted the widespread application of intelligent architectural generation methods. GANs have great potential in the field of architectural design and can provide a more efficient, flexible, and diverse design process. However, further research and development are needed to address the challenges and limitations of using GANs in this field.

This article explores the wide-ranging impact of inviting architecture students to increase conscious somatic awareness of their body and function, and the effects on their design process. This paper analyses the results of a Movement Awareness Intervention conducted prior to students undertaking their usual architectural design studio at the Queensland University of Technology, Brisbane, Australia. The impact of a global trend in extensive use of digital design tools has resulted in impacts on components in the architecture design process that appear to be slipping under the radar in architecture education and practice. This article addresses issues raised by Juhani Pallasmaa and Paolo Belardi, bolstered by neuroscience research by Harry Mallgrave and colleagues, to explore the impact of heightened conscious bodily awareness upon the cognitive design thinking processes required in the architecture. The case study research using mixed data collection methods on 39 participants draws upon surveys, hand notations, and audio interviews to track participant perceptions of the impact on their design process in action. Analysis of the data produced in this study addresses the concerns raised by theses seminal writers. This paper argues for new approaches to reconfiguring and recalibrating of emotional, cognitive, and physical stimulants that were once invisibly physically embedded in the traditional architectural design process to work with digital design technology.

Sketching is a design tool that can be assumed to be ill-structured, does not offer exact solutions, is intuitive, and is open-ended in the initial stages of architectural design. Sketching creates an opportunity for architects to release their creativity and intuition, giving rise to spontaneous ideas and concepts in an organic and natural way. During the initial design phases, like in the conceptual stage of the design, designers receive aid from conventional sketching as their concepts and ideas can easily transform into tangible, real-world forms. With the development of digital design methods like CAD (computer-aided design) in pursuit of AI (artificial intelligence), it has been accepted that manual sketches are no longer the only method used in the design process, and the trend toward using new methods has begun. The diversity and evolution of tools used in architectural design, together with the integration of CAD, AI, and traditional sketching techniques, have contributed to the development of architectural design and facilitated enhanced collaboration, visualization, and efficiency across the design process. As a result, it has evolved to embrace the use of CAD, which was the first method adopted from these developments, as a basic skill in the field of architectural design education. This shift places a strong emphasis on the professional field of architectural design while also encouraging students to explore the innovative potential of CAD for design purposes. CAD presents architects with a robust platform that facilitates the creation of intricate designs and precise measurements during the initial stages of the design process. Following CAD, the development of AI-driven design tools motivates architecture students and designers to transform their concepts into concrete designs. Although it is known that each method mentioned has its own positive or negative aspects, it is not possible to say that any of them is used alone in architectural design processes. At this point, combining the design process with CAD and AI-supported design tools, as well as traditional manual sketching in architecture, helps develop a diverse and adaptable skill set in design. Integrating digital design tools into the architectural field emphasizes the enduring importance of traditional sketches, especially in terms of inspiration and conceptualization in architectural design, while also updating the design process. This document aims to explore the progression of employing diverse design tools, namely manual sketching, CAD, and AI-driven design tools, throughout the architectural design process. This paper undertakes a comparative analysis of using computational design tools instead of traditional sketching with pen and pencil, aiming to juxtapose their respective benefits and drawbacks. In conclusion, although it is not yet possible to assert the superiority of one method over the other, it is evident that traditional sketching continues to hold significant relevance and effectiveness in the design process despite its long-term use.

Purpose Developing a human-centered design understanding in built environment-related professions and enabling them to encompass diversity are crucial for the improvement of more inclusive environments. Considering the value of guiding experiences of people with disabilities for more inclusive design practice and increasing the awareness of professionals with disabilities in design and building practice plays a key role in achieving this goal. There is a growing effort to implement inclusive and universal design issues to the educational programs of design and related disciplines for about two decades. Contrary to the developments in the pedagogy of “core” design disciplines, human-centered design perspective seems not to be widespread enough in the education of so-called “peripheral” occupations of design, like architectural drafting, especially in Turkey. Design Thinking (DT) approach, which is defined as a way of thinking, is in fact widely used in the design-related fields. In such a need of human-centered and creative problem solving, the approach seems to provide a potential to raise awareness about user-oriented design in such peripheral occupations like architectural drafting education. Considering the widening use of strategies of DT also in non-design fields, the research out of which this article comes from involves a special adaption of the approach. Departing from the ultimate aim “to raise awareness of hearing-impaired architectural drafting students about user oriented architectural design,” it applies the strategies of the DT to this special case and reports the process and its findings, hence not only providing a special instance of the model but also revealing its potential contribution to peripheral or non-design disciplines. Design/Methodology/Approach Since it particularly focuses on understanding of human behavior, provides flexible and holistic tools to investigate such phenomena and since it is based on a systematic and reflective process, the present research was carried out through qualitative research approach and its tools. Findings Study showed that in relation to hearing-impaired students’ underlined need for getting familiarized with the process of architectural design and focusing on human-centered design approach, present application of Design Thinking strategy worked effectively to provide basic information about architectural design, design process, and related tasks and user needs as well, as part of design process for hearing-impaired architectural drafting students with a certain level of hearing loss and language ability. Research Limitations/Implications Since the research was embedded within the existing educational system, data collection and observation processes had to be defined according to these boundaries. Also the students’ level of language abilities and their limited background about their field of study, because that they were first year students were the main limitations of the study. Apart from its aforementioned outcome, the research was a means of expanding the application of the initial DT model, and it could be seen as a contribution to the existing studies concerning the education of the hearing-impaired students. In general, the research illustrated that DT, as a carefully developed approach to be employed particularly for non-design occupations, could also be effectively used to teach design process for disabled design professionals. Consequently, it is thought that it could be applied to the formulation of courses such as; environmental design, design for all, inclusive design, as well as be utilized for students developing empathy with users, familiarizing with observation and interview techniques, and as a means of quick and systematic problem solving sessions. Practical Implications As it might be expected the study primarily contributes to the education of the hearing-impaired students. It helped students to develop an understanding of design process as well as develop their professional schemata (i.e. their conceptual vocabulary). As a research it provides a foundational knowledge concerning application of DT strategies in a specific field of study. Social Implications By nature, one of the basic problems confronting students with disabilities is to make them an integrated part of the society, from daily life to some specialized situations such as professional life and their education. Researcher strongly believes that this study has had implications as such although it was not primarily involved with such a goal. Originality/Value As it might be guessed the present study might be considered as a part of and a contribution to a larger research tradition evolving around the Design Thinking approach, i.e. its application and adaptation to different areas and field, and development of the strategy itself. On the other hand, since it adapts and applies DT to a specific case, and an original problem situation, actually a very rarely addressed one. As such, while it might be considered as a special contribution to that specific tradition, at the same time its primary contribution is to the education of the hearing-impaired students, and its pedagogy.

This paper investigates the interaction between reality and imagination in the architectural design process. It engages with four inter-related inquiries. First, the interplay between reality and imagination in the architectural design process in student design-build live projects. Second, the interplay of reality and imagination for different agents in the architectural design process. Third, how the work of John Hejduk (1929-2000) enables a reappraisal of conceptions of reality and imagination in architectural design. Fourth, we address a live project for The Story Museum in Oxford, UK – a physical architectural space concerned with imaginary spaces – that suggests how an understanding of reality and imagination might be deepened in the architectural design process.The text reappraises the interplay of reality and imagination in architectural design as a cognitive process. There are two aims: to reassess empirical responses and received wisdom about what is real and what is imagined in architectural design; and to reassess the perception of differences between imagination and reality occurring across education and practice. ‘Thing Theory’ is proposed as a conceptual framework which allows us to improve our understanding of how architectural designs emerge, are transformed in the designer's mind, how architects communicate them to others and how they are understood and shared by others. Reference is also made to interviews with prominent architects. The term ‘thing’ was repeatedly used by these architects to describe moments in the design process when a break from reality had occurred. In these moments, subject and object seemed at their most intertwined. This moment is strong because it is so flexible in responding to change and managing complexity. It is also weak because it is a time when the designer tends to neglect vital everyday constraints such as occupation and ethics. However, this is a key moment because it allows possible future realities to emerge.

Instrumentalization of the fluidity phenomenon in architectural design

PurposeThe purpose of this paper is to develop a framework integrating risk management (RM) into the architectural design process (ADP) as an approach for delivering sustainable construction projects.Design/methodology/approachA research methodology, which consisted of literature review and field study, is designed to accomplish four objectives. First, to provide a comprehensive literature review of the concepts of sustainability, ADP and RM. Second, to present and synthesis the results of two relevant studies focused on identifying, quantifying and classifying the risks associated with ADP; and investigating the perception and application of Egyptian architectural design firms (ADFs) towards integrating RM into ADP as an approach for delivering sustainable construction projects. Third, to develop a framework that integrates RM into ADP towards delivering sustainable construction projects. Finally, to draw conclusions and recommendations to improve the practice of delivering sustainable construction projects among ADFs, construction professionals and governmental authorities.FindingsADP is a fundamental phase of the construction process because the decisions adopted during this phase affect the project performance throughout its life cycle. While RM is widely applied in different sectors of the construction industry, its application in ADP received scant attention in construction literature. The research identified 18 key risks that affect the sustainable delivery of construction projects during ADP. The architect, the client and the project manager are the highest ranked responsible parties for the occurrence of these key risks. The field study highlighted the need to develop a framework to facilitate integrating RM into ADP.Research limitations/implicationsThis paper focused only on the integration of RM into ADP.Originality/valueThe conducted literature review and field study provided an in-depth understanding of the key risks that affect the sustainable delivery of construction projects during ADP. Through its five stages, the proposed framework is expected to serve as a foundation for integrating RM into ADP as an approach for delivering sustainable projects. This ideology has received scant attention in construction literature. The developed framework represents a synthesis that is novel and creative in thought and adds value to the knowledge in a manner that has not previously occurred.
