summary	This paper outlines a research project that explores the participation in, and perception of, advanced technologies in architectural professional practice through a sociotechnical lens and presents empirical research findings from an online survey distributed to employees in five large-scale architectural practices in Sydney, Australia. This argues that while the computational design paradigm might be well accepted, understood, and documented in academic research contexts, the extent and ways that computational design thinking and methods are put-into-practice has to date been less explored. In engineering and construction, technology adoption studies since the mid 1990s have measured information technology (IT) use (Howard et al. 1998; Samuelson and Björk 2013). In architecture, research has also focused on quantifying IT use (Cichocka 2017), as well as the examination of specific practices such as building information modelling (BIM) (Cardoso Llach 2017; Herr and Fischer 2017; Son et al. 2015). With the notable exceptions of Daniel Cardoso Llach (2015; 2017) and Yanni Loukissas (2012), few scholars have explored advanced technologies in architectural practice from a sociotechnical perspective. This paper argues that a sociotechnical lens can net valuable insights into advanced technology engagement to inform pedagogical approaches in architectural education as well as strategies for continuing professional development.

title	Sustainable Design and Construction: New Approaches Towards Sustainable Manufacturing
source	CAAD \| INNOVATION \| PRACTICE [6th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2012 / ISBN 978-99958-2-063-3], Manama (Kingdom of Bahrain), 21-23 February 2012, pp. 241-251
summary	Ecological and environmental issues are playing an important and larger role in corporate and manufacturing strategies. For complete creative design process, buildings require both for construction and manufacturing, due to their comparatively long life cycle for maintenance, significant raw material and energy resources. Thinking in terms of product life cycles is one of the challenges facing manufacturers today. “Life Cycle Management” (LCM) considers the product life cycle as a whole and optimizes the interaction of product design, construction, manufacturing and life cycle activities. The goal of this approach is to protect resources and maximize the effectiveness during usage by means of Life Cycle Assessment, Product Data Management, Technical Support and last but not least by Life Cycle Costing. In this paper the environmental consciousness issues pertaining to design, construction, manufacturing and operations management are presented through computer intelligent technologies of this 21century. So, this paper shows the existing approaches of LCM and discusses their visions and further development.

title	Pedagogic Approach in the Age of Parametric Architecture: Experimental method for teaching architectural design studio to 3rd year level students
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 211-226
summary	In this era, Architectural Design Practice is faced with a paradigm shift in its conventional approaches towards computational methods. In this regard, it is considered a pedagogic challenge to boost up knowledge and skills of architectural students’ towards an advanced approach of architectural design that emphasizes the potentials and complexity of computational environments and parametric tools for design problem solving. For introducing the concept of Parametric Oriented Design Methods to 3rd year level architectural students, an experimental pedagogic course was designed in the scholastic year of 2012-2013 at German Jordanian University GJU (School of Architecture and Built Environment SABE) to approach this concept. In the preparation phase, the experimental course was designed to incorporate structured instructing and training method to be consecutively performed within experimental lab environment to target predetermined learning outcomes and goals. The involved students were intentionally classified into three levels of previous involvement associated with the related software operating skills and computational design exposure. In the implementation phase, the predetermined instructing and training procedures were performed in the controlled environment according to the planned tasks and time intervals. Preceded tactics were prepared to be executed to resolve various anticipated complication. In this phase also, students’ performance and comprehension capacity were observed and recorded. In data analysis phase, the observed results were verified and correlations were recognized. In the final phase, conclusions were established and recommendations for further related pedagogic experiments were introduced.

title	Simulation Heuristics for Urban Design
source	In Mueller Arisona et al (eds), Digital Urban Modelling and Simulation: Communications in Computer and Information Science, Springer, Heidelberg, 2012
summary	Designing simulations for urban design not only requires explicit performance criteria of planning standards but a synthesis of implicit design objectives, that we will call ‘purpose rules’, with computational approaches. The former would at most lead to automation of the existing planning processes for speed and evaluation, the latter to an understanding of perceived urban qualities and their effect on the planning of cities. In order to transform purpose rules into encoded principles we argue that the focus should not be on defining parametric constraints and quantities, but on aligning the perceptual properties of the simulations with the strategies of the stakeholders (planner/ urban designer/ architect/ developer/ community). Using projects from the Computational Design and Research group at Aedas [CDR] as examples, this chapter will discuss how an open framework of lightweight applications with simple functionality can be integrated into the design and planning process by using computational simulations as urban design heuristics.

title	Tactics of interactivity in Virtual Reality: Learning from 3d game tools
doi	https://doi.org/10.52842/conf.caadria.2012.223
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 223–232
summary	The present paper tries to explore the potential of visual-heavy tools in the creation of virtual reality worlds, with an emphasis on tools borrowed from 3d electronic games. Compared to earlier approaches in virtual reality creation the paper focuses on game design tools and provides a basic framework for interaction in virtual reality, based on classic rather than digital representations, which is then expanded using digital representations. In the second part of the paper a game creation tool is assessed based on its potential not only of usability but also on guiding the designer in specific paths to designing virtual worlds. The assessment is based on a case study of interaction design.

title	An Integral Approach to Structural Optimization and Fabrication
doi	https://doi.org/10.52842/conf.acadia.2012.491
source	ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 491-497
summary	Abstract Integral structural optimization and fabrication seeks the synthesis of two original approaches; that of topological optimization (TO) and robotic hotwire cutting (HWC). TO allows for the reduction of up to 70% of the volume of concrete to support a given structure. A strength of the method is that it allows to come up with structural designs that lie beyond the grasp of traditional means of design. A design space is a discretized volume, delimiting where the optimization will take place. The number of cells used to discretize the design space thus sets the resolution of the TO. While the approach of the application of TO as a constitutive design tool centers on structural aspects in the design phase, the outcome of this process are structures that cannot be realized within a conventional budget. As such the ensuing design is optimal in a narrow sense; whilst optimal structurally though, construction can be prove to be prohibitively expensive. This paper reports ongoing research efforts on the development of a cost effective methodology for the realization of TO concrete structures using HWC.

summary	Integral structural optimization and fabrication seeks the synthesis of two original approaches; that of topological optimization (TO) and robotic hotwire cutting (HWC) (Mcgee 2011). TO allows for the reduction of up to 70% of the volume of concrete to support a given structure (Sondergaard & Dombernowsky 2011). A strength of the method is that it allows to come up with structural designs that lie beyond the grasp of traditional means of design. A design space is a discretized volume, delimiting where the optimization will take place. The number of cells used to discretize the design space thus sets the resolution of the TO. While the approach of the application of TO as a constitutive design tool centers on structural aspects in the design phase (Xie 2010), the outcome of this process are structures that cannot be realized within a conventional budget. As such the ensuing design is optimal in a narrow sense; whilst optimal structurally though, construction can be prove to be prohibitively expensive.

title	Synthesizing Design Performance: An Evolutionary Approach to Multidisciplinary Design Search
doi	https://doi.org/10.52842/conf.acadia.2012.067
source	ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 67-75
summary	Design is a goal oriented decision-making activity. Design is ill defined and requiring of synthetic approaches to weighing and understanding tradeoffs amongst soft and hard objectives, and the imprecise and or computationally explicit criteria and goals. In this regard designers in contemporary practice face a crisis of sorts. How do we achieve performance under large degrees of uncertainty and limited design cycle time? How do we better design for integrating performance? Fundamentally design teams, are not typically given enough time nor the best tools to design explore, to generate design alternatives, and then evolve solution quality to search for best fit through expansive design solution spaces. Given the complex criteria for defining performance in architecture our research approach experiments upon an evolutionary and integrative computational strategy to expand the solution space of a design problem as well as pre-sort and qualify candidate designs. We present technology and methodology that supports rapid development of design problem solution spaces in which three design domains objectives have multi-directional impact on each other. The research describes the use of an evolutionary approach in which a genetic algorithm is used as a means to automate the design alternative population as well as to facilitate multidisciplinary design domain optimization. The paper provides a technical description of the prototype design, one that integrates associative parametric modeling with an energy use intensity evaluation and with a financial pro forma. The initial results of the research are presented and analyzed including impacts on design process; the impacts on design uncertainty and design cycle latency; and the affordances for ‘designing-in’ performance and managing project complexity. A summary discussion is developed which describes a future cloud implementation and the future extensions into other domains, scales, tectonic and system detail.

title	Hybridizing Digital Fabrication Techniques
source	CAAD \| INNOVATION \| PRACTICE [6th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2012 / ISBN 978-99958-2-063-3], Manama (Kingdom of Bahrain), 21-23 February 2012, pp. 103-114
summary	The use of digital fabrication in the production and making of architecture is becoming a prevalent vehicle for the design process. As a result, there is a growing demand for computer-aided design (CAD) skills, computer-aided manufacturing (CAM) logic, parametric modeling and digital fabrication in student education. This paper will highlight three student projects that look to ingrate computational prototyping with digital fabrication techniques in the production of architecture. The goal is to hybridize fabrication techniques of sectioning, tessellating and folding to educate students in CAD, CAM, parametric modeling and digital fabrication. Rather than repeating conventional approaches or recreating from precedent, mixing techniques challenges students to understand the CAD technique or parameters for modeling, translate for CAM production and deal with real world constraints of materials, time and tectonics. In the end, these projects are critical of the digital and projectively speculate on the architectural detail in an age of digital ubiquity.

title	Real-time rendering of large building information models: Current state vs. state-of-the-art
doi	https://doi.org/10.52842/conf.caadria.2012.647
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 647–656
summary	With the use of Building Information Models (BIM), real-time 3D visualisations have become a natural tool in order to communicate ideas and share information between all involved parties in a project. Currently, several different BIM viewers are available for the purpose of interactive presentations and design reviews. However, as BIMs become larger and more detailed, it provides a challenge for available software solutions to manage them interactively. In this paper we present our findings from analysing three commonly used BIM viewers - Tekla BIMSight, Autodesk Navisworks and Solibri Model Viewer - in terms of real-time rendering performance. In addition we have developed a prototype BIM viewer to test modern approaches for efficient real-time rendering. Specifically, we have implemented the latest version of the Coherent Hierarchical Culling algorithm. Our results show that existing BIM viewers all share limitations in their ability to handle large and complex BIMs interactively. However, for the same test models, our prototype BIM viewer enables smooth real-time performance with no visual artefacts. The results from our tests thus shows that the technology to enable correct real-time rendering of large and complex BIMs is already accessible, but are currently not utilised by any of the tested BIM viewers.

summary	This paper deals with the process of synthesizing the innovative concepts, and especially with software and methodological support of this process. Our approach emphasizes the importance of the interpretation of the suggestions, which are generated by the system of software and methodological support of conceptual design. Just an interpretation is in this systems usually missing. Herein described method is based on the interconnection of the contexts in which the solution lies. For this context’s interconnection a psychological approaches are used (especially the mind mapping). The core of this interpretation method is creating of the interpretation map.

summary	Learning in architecture has shifted from an individual focused approach to a larger system of interacting individuals in a situated, tool-mediated and socio-technical context. In addition to developing essential skills to work with diverse design software and taking part in collaborative design activities, learners also need to be equipped with competencies that will allow them to operate intelligently outside of situations of distributed cognitions. The challenge in present educational climate is to develop pedagogical approaches where situations of distributed cognition are not the ends themselves but are the means for improving mastery of solo competencies. The paper contributes to the current discussion about the need to re-orient architectural education and proposes a pedagogical framework for the development of a new web-based teaching/learning environment (socio-cognitive eco-system) as an integrated platform to support both autonomous and distributed learning.

summary	This paper aims to investigate the potential of both open source software and new media (esp. computer vision and augmented reality) as tools for architectural design and education. The examples illustrated in the paper would be drawn mainly from students’ projects done as part of their AA Media Studies Course submission at the AA School of Architecture (AA) during the academic years from 2011/2012 to 2012/2013. The paper outlines the main approaches, which students have chosen to implement, both directly and indirectly, these new media and tools into their studio work at the AA. Section 1 briefly introduces a range of currently available open source computational design toolkits that are deemed useful for quick implementation of computer vision and augmented reality technologies. The related programming languages, softwares and hardwares would also be introduced and described accordingly. Sections 2 and 3 are accompanied with a visual catalogue of students’ projects to better illustrate the diversity in the understanding and implementation of computer vision and augmented reality technologies in architectural design. Section 4 serves to conclude the paper by first discussing briefly the feedback from students at the end of the course before clarifying the context of the research and thus its relation to recent work done by others using similar technologies.

summary	What if we had materials that weren’t solid and static like traditional building materials are? What if these materials could dynamically change and adapt to varying environmental situations and stimulations and evolve and learn over time? What if they were autonomous, self-sufficient and independent but could communicate with each other and exchange information? What would this “living matter” mean for architecture and the way we perceive the built environment? This paper looks briefly at current concepts and investigations in regards to programmable matter that occupy various areas of architectural research. It then goes into detail in describing the most recent smart material installation “Resinance” that was supervised by Manuel Kretzer and Benjamin Dillenburger and realized by the 2012/13 Master of Advanced Studies class as part of the materiability research at the Chair for CAAD, ETH Zürich in March 2013. The highly speculative sculpture links approaches in generative design, digital fabrication, physical/ubiquitous computing, distributed networks, swarm behavior and agent-based communication with bioinspiration and organic simulation in a responsive entity that reacts to user input and adapts its behavior over time.

Biodigital Intelligent Systems - Proceedings of the XXVIII Conference of the Iberoamerican Society of Digital Graphics (SIGraDi 2024) - ISBN 978-9915-9635-2-5, iBAG-UIC Barcelona, Spain, 13-15 November 2024, pp. 1825–1836
summary	Brazilian energy performance standard for residences (INI-R) classifies residential buildings based on energy efficiency, focusing on building envelope standards to ensure quality and conservation. While beneficial, the standard poses challenges for designers unfamiliar with its parameters. Marble (2012) highlights the need for specialized teams in multidisciplinary projects, yet designers often rely on intuitive approaches, delaying compliance checks (Al-Saadani; Bleil de Souza, 2018). There is a need for simplified validation methods in design software to assist designers without programming expertise. Integrating performance standards into Building Information Modeling (BIM) models offers a potential solution, allowing early parameter visualization and continuous design reassessment. A study incorporating INI-R criteria into a BIM workflow revealed challenges in software syntax and tools. Transparent elements were found to influence design massing, and there were limitations in automating tasks like extracting glazed areas from window families. Despite its potential, BIM needs refinement to improve compliance with design standards.

source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 569–578
summary	This paper presents a comparative study of Architecture students who study in a tradition learning environment and Innovative Design students who study in a 3D virtual environment. Both groups share the same objectives. Their learning pattern went through a three-step learning process where issues related to Design Composition theory were inserted. A survey and an in-depth interview showed a discontinued creative process amongst Architecture students due to class management. It showed that Innovative Design students should have more small assignments to better understand issues related to Design Composition theory with emphasis on developing their communication skill in using Visual Training technical terms. The differences between the two learning approaches were discussed.

title	Graded Territories: Towards the Design, Specification and Simulation of Materially Graded Bending Active Structures"

source	ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 79-86
summary	The ability to make materials with bespoke behavior affords new perspectives on incorporating material properties within the design process not available through natural materials. This paper reports the design and assembly of two bending-active, fibre-reinforced composite structures. Within these structures, the property of bending is activated and varied through bespoke material means so as to match a desired form. Within the architectural design process, formal control depends upon design approaches for material specification and simulation that consider behavior at the level of the material element as well as the structure. We describe an evolving approach to material specification and simulation, and highlight the digital and material considerations that frame the process.

title	Point Cloud Segmentation for Building Reuse - Construction of digital twins in early phase building reuse projects

summary	Point cloud processing has come a long way in the past years. Advances in computer vision (CV) and machine learning (ML) have enabled its automated recognition and processing. However, few of those developments have made it through to the Architecture, Engineering and Construction (AEC) industry. Here, optimizing those workflows can reduce time spent on early-phase projects, which otherwise could be spent on developing innovative design solutions. Simplifying the processing of building point cloud scans makes it more accessible and therefore, usable for design, planning and decision-making. Furthermore, automated processing can also ensure that point clouds are processed consistently and accurately, reducing the potential for human error. This work is part of a larger effort to optimize early-phase design processes to promote the reuse of vacant buildings. It focuses on technical solutions to automate the reconstruction of point clouds into a digital twin as a simplified solid 3D element model.

(2017), are compared in their ability to apply semantic as well as instance segmentation to point clouds. Further it relies on the S3DIS Armeni et al. (2017), NYU v2 Silberman et al. (2012) and Matterport Ramakrishnan et al. (2021) data sets for training. Here, the authors aim to establish a workflow that reduces the effort for users to process their point clouds and obtain object-based models. The findings of this research show that although pure point cloud-based ML models enable a greater degree of flexibility, they incur a high computational cost. We found, that using RGB-D images for classifications and segmentation simplifies the complexity of the ML model but leads to additional requirements for the data set. These can be mitigated in the initial process of capturing the building or by extracting the depth data from the point cloud.

summary	As part of an ongoing research project, this Paper is intended to present some of the main questions emerged when preparing a series of experiments for the generation and arrangement of facade elements in mass customized dwellings. In general, two differing approaches have been tried in panelization of regular and irregular facades in buildings. The first one is based on dimensional coordination strategies and is regarded as being the most efficient in terms of material usage and production rationalization. The other is derived from the more open strategy of deriving individual panel dimensions from a UV grid and its transformations.

summary	Deliberately introduced unidirectional material weakening is explored as a means of producing material properties which exploit natural material tendencies rather than as a means to compensate for them. Such anisotropic operations take natural systems as a point of departure for man-made approaches to the augmentation of building performance in the realm of solar shading, but also for the creation of materially complex architectural environments.
