summary	The "PURE Tension" Pavilion is a lightweight, rapidly deployable, tensioned membrane structure and portable charging station commissioned by Volvo Car Italia to showcase the new Volvo V60 Hybrid Electric Diesel car. Officially launched in Milan, Italy in October 2013, this experimental structure was developed through a process of rigorous research and development that investigated methods of associative modelling, dynamic mesh relaxation, geometric rationalization, solar incidence analysis, membrane panelling, and material performance. It is an experimental structure that, similar to a concept car, is a working prototype that speculates on the potential future of personal mobility and alternative energy sources for transportation while also exploring digital design methodologies and innovative structural solutions. This paper will illustrate the design, development and fabrication processes involved in realizing this structure.

title	Collaboration Workflow Simplified: Reduction of Device Overhead for Integrated Design Collaboration
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 591-602.
summary	Design collaboration relies on cognitive tools such as analog media and digital peripheral devices, and shows the characteristics of distributed cognition. It is a social and complex activity involving multiple agents communicating and using external cognitive tools to encode, decode, and share information in the process of collaborative task completion. The systems supporting this activity should meet the ’principle of least collaboration effort’ [4] that proposes that agents in collaboration minimize their effort in presentation and acceptance of information. Yet, current collaboration systems are dispersed mixed media that is often overloaded with representations and functionality, thus preventing seam- less information sharing. Designers are required to spend extra effort collecting information using peripheral devices and in system management when sharing information. The goal of this study is to understand these overheads in infor- mation collection and sharing using peripheral devices, and to provide designers with a supportive platform to enhance collaboration using both analog and digital media. In this paper, we first review available peripheral devices such as smart pens, digital cameras, and voice recorders, as well as existing collaboration sup- porting software systems for their benefits and deficiencies in collaboration. We then present ’DiNa’, a collaboration platform that is envisioned to improve pro- ductivity and reduce redundant work by integrating peripheral devices into the collaboration workflow. We demonstrate a possible workflow using this system through several scenarios where designers collaborate in performing a series of design tasks. We hope to bring attention to the importance least collaborative effort in designing systems to support real-world collaboration.

title	Web Based BIM for Modular House Development: Query Approach in Consumer Participatory Design
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 559-570
summary	The paper describes the relationship of client’s requirements and available design options of the proposed system by examples of its current prototype. By integrating the nature of modularity in prefabricated housing design, a proposed web-based design system will provide information filtering questionnaires to assist customers in selecting appropriate design components. A methodology has been developed that can generate design options based on the client’s needs and available modular components from selected product suppliers making it possible to simulate the final design before processing orders for assembling and manufacturing. Overall, the research demonstrates the power of internet that acts as a feedback loop to receive the information from clients, streamline the communication in between design teams, and integrate all products and materials together.

title	Some Phenomena of Spatial Interaction in the Networked Spaces
source	CAADRIA 2002 [Proceedings of the 7th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 983-2473-42-X] Cyberjaya (Malaysia) 18–20 April 2002, pp. 039-47
doi	https://doi.org/10.52842/conf.caadria.2002.039
summary	As a result of the network-based nature of Internet and communications technologies, a new spatial form, which is defined as networked spaces by this research, is emerging. This paper provides a significant theoretical framework to unpack complex spatial relationships caused by the networked spaces. Such emerging design approach challenges the design thinking, design process and design knowledge of architecture, urban design, as well as media design.

title	Comprehensive analysis of the vitality of urban central activities zone based on multi-source data - Case studies of Lujiazui and other sub-districts in Shanghai CAZ
source	A. Globa, J. van Ameijde, A. Fingrut, N. Kim, T.T.S. Lo (eds.), PROJECTIONS - Proceedings of the 26th CAADRIA Conference - Volume 2, The Chinese University of Hong Kong and Online, Hong Kong, 29 March - 1 April 2021, pp. 549-558
doi	https://doi.org/10.52842/conf.caadria.2021.2.549
summary	With the use of the concept Central Activities Zone in the Shanghai City Master Plan (2017-2035) to replace the traditional concept of Central Business District, core areas such as Shanghai Lujiazui will be given more connotations in the future construction and development. In the context of todays continuous urbanization and high-speed capital flow, how to identify the development status and vitality characteristics is a prerequisite for creating a high-quality Central Activities Zone. Taking Shanghai Lujiazui sub-district etc. as an example, the vitality value of weekday and weekend as well as 19 indexes including density of functional facilities and building morphology is quantified by obtaining multi-source big data. Meanwhile, the correlation between various indexes and the vitality characteristics of the Central Activities Zone are tried to summarize in this paper. Finally, a neural network regression model is built to bridge the design scheme and vitality values to realize the prediction of the vitality of the Central Activities Zone. The data analysis method proposed in this paper is versatile and efficient, and can be well integrated into the urban big data platform and the City Information Modeling, and provides reliable reference suggestions for the real-time evaluation of future urban construction.

title	Energy-driven Intelligent Generative Urban Design, Based on Deep Reinforcement Learning Method With a Nested Deep Q-R Network
source	Jeroen van Ameijde, Nicole Gardner, Kyung Hoon Hyun, Dan Luo, Urvi Sheth (eds.), POST-CARBON - Proceedings of the 27th CAADRIA Conference, Sydney, 9-15 April 2022, pp. 233-242
doi	https://doi.org/10.52842/conf.caadria.2022.1.233
summary	To attain "carbon neutrality," lowering urban energy use and increasing the use of renewable resources have become critical concerns for urban planning and architectural design. Traditional energy consumption evaluation tools have a high operational threshold, requiring specific parameter settings and cross-disciplinary knowledge of building physics. As a result, it is difficult for architects to manage energy issues through 'trial and error' in the design process. The purpose of this study is to develop an automated workflow capable of providing urban configurations that minimizing the energy use while maximizing rooftop photovoltaic power potential. Based on shape grammar, parametric meta models of three different urban forms were developed and batch simulated for its energy performance. Deep reinforcement learning (DRL) is introduced to find the optimal solution of the urban geometry. A neural network was created to fit a real-time mapping of urban form indicators to energy performance and was utilized to predict reward for the DRL process, namely a Deep R-Network, while nested within a Deep Q-Network. The workflow proposed in this paper promotes efficiency in optimizing the energy performance of solutions in the early stages of design, as well as facilitating a collaborative design process with human-machine interaction.

title	An Approach to 3D Conceptual Modelling
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	This article presents a 3D user interface required by the development of conceptual modeling. This 3D user interface provides a new structure for solving the problems of difficult interface operations and complicated commands due to the application of CAD 2D interface for controlling 3D environment. The 3D user interface integrates the controlling actions of “seeing – moving –seeing” while designers are operating CAD (Schön and Wiggins, 1992). Simple gestures are used to control the operations instead. The interface also provides a spatial positioning method which helps designers to eliminate the commands of converting a coordinate axis. The study aims to discuss the provision of more intuitively interactive control through CAD so as to fulfil the needs of designers. In our practices and experiments, a pair of LED gloves equipped with two CCD cameras for capturing is used to sense the motions of hands and positions in 3D. In addition, circuit design is applied to convert the motions of hands including selecting, browsing, zoom in / zoom out and rotating to LED switches in different colours so as to identify images.

title	Reinforcement Learning for Architectural Design-Build - Opportunity of Machine Learning in a Material-informed Circular Design Strategy
source	A. Globa, J. van Ameijde, A. Fingrut, N. Kim, T.T.S. Lo (eds.), PROJECTIONS - Proceedings of the 26th CAADRIA Conference - Volume 1, The Chinese University of Hong Kong and Online, Hong Kong, 29 March - 1 April 2021, pp. 171-180
doi	https://doi.org/10.52842/conf.caadria.2021.1.171
summary	This paper discusses the potentials of reinforcement learning in game engine for design, implementation, and construction of architecture. It inaugurates a new design tool that promotes a material-informed design-build workflow for architectural design and construction industries that achieves a comprehensive circular economy. As a proof of concept, it uses the project Reform Standard, a machine-learning-based searching system that designs new shell structures composed of existing wasted materials, as a demonstration to discuss how reinforcement learning, machine vision and automated searching algorithm in the game engine can promote a material-aware design and converts wastes into construction materials. The demonstrator project sorts and transforms irregular chunks of wasted broken plastics into a new form. Instead of recycling those wastes in an energy-intensive process, the game engine is capable of finding the intricacy and new machine-oriented aesthetics in those otherwise neglected wastes. Furthermore, future research directions such as robotic-aided construction are discussed by exposing the potentials and problems in the demonstrated project. Finally, the future circular strategy is discussed beyond the demonstrated tests and local uses. The standardization of material, legislation and material lifecycle needs to be comprehensively considered and designed by architects and designers during conceptual design phase.

title	A Body-Surrounding Study In Physical, Virtual and Mental Spaces
source	CAADRIA 2003 [Proceedings of the 8th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 974-9584-13-9] Bangkok Thailand 18-20 October 2003, pp. 343-358
doi	https://doi.org/10.52842/conf.caadria.2003.343
summary	With the flourishing of architectural creation via all kinds of media, a comparison among physical, virtual and mental space becomes a fevered issue about spatiality due to the similar sense of space. This study reveals that even if the spaces constructed with distinct essence, a body-surrounding relation is an efficient way to formalize the problems of spatiality and relativity among three typical spaces. The sense of space and relative position reasoning were depicted with the Space-Transforming Test and the SpaceComprehending Test as a new concept about spatiality in general.

summary	Conceptual modeling is an actively creative stage in a design process. Through hand modeling and manipulation of different kinds of modeling tool kits for specific materials, designers are able to generate forms. This article presents a tangible human-computer interface of a C-StressBall for form manipulation and a C-BenchWhirler for visual control. They create a new way of interaction between the virtual world and the physical space. They are aimed to ease the operation in design process by using CAD.

summary	The spatial nature of cyberspace has not yet fully defined. This paper presents both analogous and comparative approach to reveal the spatial nature of cyberspace based on a conventional architecture theory, Space Syntax. Two types of city, the physical and the virtual, are compared in order to realize the configurational properties of cyberspace. The findings of this study indicate that the theoretical assumptions of existing architecture theories need to be altered so that cyberspace can be well interpret and understand.

title	The Role of Physical Models in Digital Design Processes
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
doi	https://doi.org/10.52842/conf.caadria.2007.x.d1s
summary	In recent years, designers have used digital media at various points of the design process, which helps expand architectural possibilities. Digital media has changed not only the architectural style, but also the design process (Lynn, 1999). In earlier times, some researchers of design thinking have looked at how the role of physical models played in traditional design processes (Millon, 1994). However, the design process has been changed when media designers used to adjust from traditional to digital. Therefore, visual thinking and cognitive behavior of designers also change while using physical models in design processes. From the synthesis of the two aforementioned disciplines, we can find that there exists a point of deficiency. That is the cognitive research about designers who use physical models in digital design processes is absent. This is discussed in the current paper.

doi	https://doi.org/10.52842/conf.caadria.2024.3.231
summary	The paper introduces the initial finding of Pleurotus ostreatus (PO) mycelium growing on the Phyllostachys makinoi (PM) bamboo substrate and taking advantage of mycelium composite's elevated compressive strength, lightweight, and thermal insulation properties; this study proposes a structural module system for a barrel vault structure. This research investigated 5:1, 2:1, and 1:1 bamboo-fiber and bamboo-powder mixtures with 5% C6H12O6 and 65% water growing in a 25°C controlled environment. Due to the powder form of the PM substate, PO mycelium has easy access to the pentosan inside the substrate. As a result, the 1:1 ratio mixture has a higher growing rate than the 5:1 and 2:1 mixture. The experiment also indicates that the mycelium composite wall thickness shall be less than 40 mm for optimal PO mycelium growth when using PM substrate.

summary	Internet-based project extranets represent a new generation of CAD tools that has been much talked about in the design professions recently. Many believe they hold considerable promise to change dramatically how design participants collaborate in the AEC industry. Yet we are only beginning to understand the real value that such project extranets provide. Clearly, empirical studies of project extranet usage are needed to illuminate the situation. This paper summarizes the results of an explorative study into the implications of such project extranets on design collaboration.

summary	In this paper, we describe Internet and Architecture (i+a), a research and teaching program, startedfour years ago at Harvard Design School, to explore the possibilities that lie in the convergence of aphysical with a virtual architecture. The approach starts with the analysis of everyday verbs and thechanges that occur in the virtualization of everyday situations, and moves on to critically rethinkexisting architectural typologies and develop new architectures that combine physical and virtualcomponents. This paper describes our experiences with the approach in the year 2001-2002. Wepresent samples of design projects as illustrative examples of new architectural typologies thatcombine the physical and virtual, and describe how incorporating technologies for virtual collaborationinto the design process can enhance architectural practice in the broadest sense.
