title	Making pavilions: Os pavilh?es temporários no contexto das faculdades de arquitetura e urbanismo [Making pavilions: The temporary pavilions in the context of schools of architecture and urbanism]
source	SIGraDi 2016 [Proceedings of the 20th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-956-7051-86-1] Argentina, Buenos Aires 9 - 11 November 2016, pp.318-325
summary	This paper aims to highlight the educational potential of the association between the architectural typology of temporary pavilions and digital fabrication process for architecture and urban planning courses. The pavilion theme is being increasingly exploited in various universities in the world, in order to work new paradigms of computational algorithmic architecture and new construction process, through digital fabrication labs. In this sense, these exercises can become a privileged and highly effective learning tool, due the impact of the integrated experience between creating (design), construction (to build) and experience (to appropriate the spaces).

summary	Healthcare design projects require the careful integration of spatial and structural requirements. Today, design teams typically resolve these requirements in two separate, largely sequential steps. In the first step, architects leverage their experience and vision to develop space plans that address program and goals. Next, based on the architect's recommended design, engineers generate and refine a structural design to address structural requirements. This manual process produces a very limited number of non optimal spatial and structural design solutions with unclear decision rationale. This paper presents the Integrated Spatial-Structural Optimization (ISSO) decision making methodology. ISSO supports design teams by helping them generate, analyze, and manage a vast number of integrated spatial and structural solutions. ISSO features a bi-level optimization workflow that has been customized for spatial and structural design of healthcare facilities. The paper describes implementation in the Dynamo parametric modeling platform, and retrospective validation of the algorithm and workflow on an industry case study to demonstrate how ISSO can help design teams generate, analyze, and manage more conceptual design options.

title	Robotic Fabrication of Non-Standard Material
source	ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp

summary	This paper illustrates a fabrication methodology through which the inherent form of large non-linear timber components was exploited in the Wood Chip Barn project by the students of Design + Make at the Architectural Association’s Hooke Park campus. Twenty distinct Y-shaped forks are employed with minimal machining in the construction of a structural truss for the building. Through this workflow, low-value branched sections of trees are transformed into complex and valuable building components using non-standard technologies. Computational techniques, including parametric algorithms and robotic fabrication methods, were used for execution of the project. The paper addresses the various challenges encountered while processing irregular material, as well as limitations of the robotic tools. Custom algorithms, codes, and post-processors were developed and integrated with existing software packages to compensate for drawbacks of industrial and parametric platforms. The project demonstrates and proves a new methodology for working with complex, large geometries which still results in a low cost, time- and quality-efficient process.

title	Development of the Integrated Management Environment of BIM Property Information for BIM-based Sustainable Design
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 487-496

summary	With the growing responsibility for the environmental load of building, the demand for sustainable building is increasing. Sus- tainable design requires an enormous amount of information, and most of this information can be captured by Building Information Modelling (BIM). In this context, the management of information in a BIM object as a container for exchanging information is necessary for analyzing a building’s sustainability. However, there are problems in generating a reliable sustainability simulation model from BIM, such as the inefficiency of required information and low accessibility to a proper BIM object. In order to provide a new approach for generating a reliable sustainability simulation model in a BIM-based design pro- cess, this study suggests the integrated management environment of the property information of a BIM object.

summary	Virtual Reality (VR) software has developed to the point where, for the architect who is averagely technically adept, it can be incorporated into the design process with reasonable effort and costs. For VR to be an effective design tool, it must add value to the design process and should give insights and opportunities not available by other methods.Previous research by the authors reported on the results of an international student workshop which focused both on the workflow (to prepare the architectural models for the new VR systems) and the spatial perception that users experienced. In this paper, we continue to explore the question: "Can low cost VR be an effective addition to the architects' design toolbox, or does it still remain a "far-fetched, high-tech expensive folly?"To do this we are working with a larger group of students, a more developed workflow and we are also expanding this to architects in practice. We will be assessing both the practicality of integrating VR into the design workflow and the spatial perception of the designer when interacting with the model. We are experimenting with additional interface tools.

title	Breaking out: New freedoms in urban (re)design work by adding immersive environments
source	International Journal of Architectural Computing vol. 14 - no. 2, 103-118
summary	Nowadays, urban planning and urban design are facing big changes in the use of different digital tools. Reaching out and engaging citizens and other stakeholders in urban design process are significant for good practice. Main problem discussed in this article is the lack of suitable tools/interfaces for instant collaboration between government, profession, and public. Article focuses on immersive environments, as full immersion could offer better notion of different proposals of urban design. As a case study, Immersive Terf is chosen; more exactly, article focuses on new approach and new development of tool Urban Redesign Terf. Deep immersive collaboration on design could free participant’s mind and increase level of freedom in design/planning process. Immersive environments have already been used in building information modeling (BIM) managment, but innovation part, presented here, are technological: significant changes in the software and walk-through big models, which is the base for urban design and urban planning process.

summary	Since the 80s, several researches have developed the theoretical notions of sound effects, sound proxemy, city sound identities, sound comfort, architectural sound prototypes which were meant to help designers consider sound in their projects. Nevertheless, taking care of the inherent sound dimensions in architectural urban projects remains an unresolved challenge. The researches of the last 30 years have shown how the sound environment qualities are forgotten in favour of visual qualities. This article presents a new method dedicated to generating simple sound sketches for architectural conception while preserving the complexity of acoustic simulation. This paper argues that the Esquis'sons! sound sketch tool reconfigures architectural design by considering an innovative view its the temporality, allowed by numeric designing tools able to intervene and offer a continuous feedback regarding sound environment.

title	Reciprocal transformations between music and architecture as a real-time supporting mechanism in urban design
source	International Journal of Architectural Computing vol. 14 - no. 4, 349-357
summary	The more complex our cities become, the more difficult it is for designers to use traditional tools for understanding and analyzing the inner essence of an eco-system such as the contemporary urban environment. Even many of the recently crafted digital tools fail to address the necessity for a more holistic design approach which captures the virtual and the physical, the immaterial and the material. Handling of massive chunks of information and classification and assessment of diverse data are nowadays more crucial than ever before. We see a significant potential in combining the fields of composition in music and architecture through the use of information technology. Merging the two fields has the intense potential to release new, innovative tools for urban designers. This article describes an innovative tool developed at the Technical University of Crete, through which an urban designer can work on the music transcription of a specific urban environment applying music compositional rules and filters in order to identify discordant entities, highlight imbalanced parts, and make design corrections. Our cities can be tuned.

title	Adaptive Decorative Building Skin
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 425-434

summary	Traditional decorative ornaments were commonly used on the building skin of traditional architecture. Nowadays in urban areas, those ornaments become less popular for they are considered old- fashioned and due to the lack of technical function that matches with the modern building designs. Based on those issue, this paper pro- posed a type of building skin that aimed to revive a new expression of traditional decorative elements by applying digital design tools and technology as well as having an adaptive function. Traditional decora- tive ornaments merged in an adaptive skin that used traditional pat- terns as a controller of the effect of environmental changes in a build- ing could provide a new expression of the use of traditional ornaments on a building in accordance with the times. Most of the adaptive building skin used kinetic techniques in order to make its formation and pattern transformable. This paper proposed a parametric-cam mechanism to transform the pattern of traditional ornament using pre- programmed analysis data of environmental changes to parametrically drive the number of rotation phase and length of nose that generated the shape of the cams. In conclusion, this paper has developed a proto- typical tool that facilitates the new approach to kinetic decorative or- naments on building skin.

doi	https://doi.org/10.52842/conf.acadia.2019.392
summary	This project applies techniques in machine learning, specifically generative adversarial networks (or GANs), to produce synthetic images intended to capture the predominant visual properties of urban places. We propose that imaging cities in this manner represents the first computational approach to documenting the Genius Loci of a city (Norberg-Schulz, 1980), which is understood to include those forms, textures, colors, and qualities of light that exemplify a particular urban location and that set it apart from similar places. Presented here are methods for the collection of urban image data, for the necessary processing and formatting of this data, and for the training of two known computational statistical models (StyleGAN (Karras et al., 2018) and Pix2Pix (Isola et al., 2016)) that identify visual patterns distinct to a given site and that reproduce these patterns to generate new images. These methods have been applied to image nine distinct urban contexts across six cities in the US and Europe, the results of which are presented here. While the product of this work is not a tool for the design of cities or building forms, but rather a method for the synthetic imaging of existing places, we nevertheless seek to situate the work in terms of computer-assisted design (CAD). In this regard, the project is demonstrative of a new approach to CAD tools. In contrast with existing tools that seek to capture the explicit intention of their user (Aish, Glynn, Sheil 2017), in applying computational statistical methods to the production of images that speak to the implicit qualities that constitute a place, this project demonstrates the unique advantages offered by such methods in capturing and expressing the tacit.

title	Cultural-Smart City: Establishing New Data-informed Practices to Plan Culture in Cities

doi	https://doi.org/10.52842/conf.caadria.2020.2.081
summary	The idea of the Creative City has encouraged planners to develop cultural policies to support creative economies, city branding, urban identity and urban quality. On the other side, the concept of Smart City introduced the possibility to create, collect and analyse data to inform decisions on cities. The two city agendas overlap in different ways, creating a Smart cultural city nexus, that propose similar goals and mixed methodologies, like the possibility to inform planning processes with big data-based technologies. In line with this direction, we introduced conceptual and methodological tools: the first tool is the definition of Hybrid Art Spaces, the second tool is the Singapore Art Maps (SAM), which uses social media data to locate art venues in cities (Tomarchio et al. 2016); the third tool is the Social Media Art Model, which establishes a relationship between social media production and art venues features. While these tools have already shown interesting analytics outcomes (Tomarchio et al. 2016), it is important to validate their utility among practitioners and to set protocols of practices. This paper presents results from semi-structured interviews and a focus group, as a first step towards assessing the usefulness of our three tools for cultural planning practice.

title	Hybrid Sentient Canopy: An implementation and visualization of proprioreceptive curiosity-based machine learning
source	ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp. 362-371
doi	https://doi.org/10.52842/conf.acadia.2016.362
summary	This paper describes the development of a sentient canopy that interacts with human visitors by using its own internal motivation. Modular curiosity-based machine learning behaviour is supported by a highly distributed system of microprocessor hardware integrated within interlinked cellular arrays of sound, light, kinetic actuators and proprioreceptive sensors in a resilient physical scaffolding system. The curiosity-based system involves exploration by employing an expert system composed of archives of information from preceding behaviours, calculating potential behaviours together with locations and applications, executing behaviour and comparing result to prediction. Prototype architectural structures entitled Sentient Canopy and Sentient Chamber developed during 2015 and 2016 were developed to support this interactive behaviour, integrating new communications protocols and firmware, and a hybrid proprioreceptive system that configured new electronics with sound, light, and motion sensing capable of internal machine sensing and externally- oriented sensing for human interaction. Proprioreception was implemented by producing custom electronics serving photoresistors, pitch-sensing microphones, and accelerometers for motion and position, coupled to sound, light and motion-based actuators and additional infrared sensors designed for sensing of human gestures. This configuration provided the machine system with the ability to calculate and detect real-time behaviour and to compare this to models of behaviour predicted within scripted routines. Testbeds located at the Living Architecture Systems Group/Philip Beesley Architect Inc. (LASG/PBAI, Waterloo/Toronto), Centre for Information Technology (CITA, Copenhagen) National Academy of Sciences (NAS) in Washington DC are illustrated.

summary	This research documents our initial experiences of using a new type of collaborative, industrial robot in the area of architecture, design, and construction. The KUKA LBR-iiwa differs from common robotic configurations in that it uses seven axes with integrated force-torque sensors and can be programmed in the Java programming language. Its force-sensitivity makes it safe to interact with, but also enables entirely new applications that use hand-guiding and utilize the force-sensors to compensate for high tolerances on building sites, similar to how we manually approach assembly tasks. Especially for the creative industry, the Java programming opens up completely new applications that would have previously required complex bus systems or industrial data interfaces. We will present a series of realized projects that showcase some of the potential of this new type of collaborative, safe robot, and discuss the advantages and limitations of the robotic system.

summary	The objective of this research project is to simulate and evaluate the effect of movement velocity and cognitive abilities on the visual perception of three groups of urban users: pedestrians, cyclists and car drivers.The simulation and analysis is based on the 3D Dynamic Visual Analysis (DVA) (Fisher-Gewirtzman, 2017). This visibility analysis model was developed in the Rhinoceros and Grasshopper software environments and is based on the conceptual model presented in Fisher-Gewirtzman (2016): a 3D Line of Sight (LOS) visibility analysis, taking into account the integrated effect of the 3D geometry of the environment and the variant elements of the view (such as the sky, trees and vegetation, buildings and building types, roads, water etc.). In this paper, the current advancement of the existing model considers the visual perception of human users employing three types of movement in the urban environment--pedestrians, cyclists and drivers--is explored.We expect this research project to exemplify the contribution of such a quantification and evaluation model to evaluating existing urban structures, and for supporting future human perception-based urban design processes.

summary	Contemporary advanced simulation software allow for a higher accuracy in the understanding of material behaviour. The increase in computational power is enabling designers to get much closer to real time physical simulations, which facilitates the inheritance of those tools in their design workflows.However, the use of those tools is normally limited to a series of specific steps within the entire workflow, rather than a feature integrated in the design process itself.Softmodelling is an open source Java application which aims to bridge this gap by seamlessly integrating physical simulations in every step of the design process, giving designers the ability to not only test structural behaviours of a given output, but also allow them to design while taking both structural stability and material behaviour into account at every stage.This paper will discuss the design and evolution of the software, as well as showcase physical prototypes which explore the possibilities of such design methods. These projects are fundamental in materialising the evolution of Softmodelling, towards becoming an application that does not only enable the design of flexible elements, but also facilitates their manufacturing and assembly into large scale structures.

summary	This paper presents an integrated workflow for interactive design of shell structures, which couples structural and environmental analysis through a multi-agent systems (MAS) for design. The work lies at the intersection of architecture, engineering and computer science research, incorporating generative design with analytical techniques. A brief review on architectural shell structures and the structural logic of reciprocal frames is described. Through the morphological study of reciprocal frames locally we seek to inform the behavior of a MAS, which integrates form-finding techniques, with daylight factor analysis (DFA) and finite element analysis (FEA) on a global configuration. An experimental design is developed in order to explore the solution space of large span free form shells with varying topologies and boundary conditions, as well as identify the relationships between local design parameters of the reciprocal frames (i.e. number of elements, profile) and the analyses (i.e. stress distribution, solar radiation) for enabling the generation of different global design alternatives. The research improves upon design decision-making latency and certainty through harnessing geometric complexity and structural form finding for early stage design. Additionally, the research improves upon design outcomes by establishing a feedback loop between design generation, analysis and performance.

Simulation tools (such as CFD) enables analysing and visualizing environmental factors (such as temperature and airflow) based on the design proper- ties and can be used to improve the building design for better perfor- mance. However, these tools have limitations in providing interactivi- ty with users for creating multiple CFD visualization results to be used for analysing design options. This research presents an integrated de- sign tool which consists of CFD and VR technologies. The proposed system visualizes CFD results in a VR environment together with ar- chitectural design. Additionally, it enables configuring CFD parame- ters within the VR environment and allows repeatedly executing simu- lation and visualizing updated results. The proposed system enables visualizing information in relationship with the actual architectural design, space configuration and thermal environment, and provides ef- ficient design feedbacks.

title	Three-dimensional visualized space and asset management system for large-scale airports: The case of Incheon International Airport
source	International Journal of Architectural Computing vol. 14 - no. 3, 233-246
summary	Large-scale airports such as Incheon International Airport have large-scale terminals, annex buildings, and numerous open spaces. An integrated space management system is required to manage these buildings and spaces efficiently. Thus, Incheon International Airport Corporation developed a three-dimensional computer-aided design–based integrated space management system. The major system development goal was to provide intuitive three-dimensional-based visual information, thereby realizing an integrated space and asset management system that does not require expert knowledge of any specific field, such as architecture. This article discusses the construction of the system and the problems that had to be resolved to achieve this goal.

title	Design optimization and robotic fabrication of tensile mesh structures: The development and simulation of a custom-made end-effector tool
source	International Journal of Architectural Computing vol. 14 - no. 4, 333-348
summary	This article presents an ongoing research, aiming to introduce a fabrication procedure for the development of tensile mesh systems. The purpose of current methodology is to establish an integrated approach that combines digital form- finding and robotic manufacturing processes by extracting data and information derived through elastic material behavior for physical implementation. This aspires to extend the capacity of robotically driven mechanisms to the fabrication of complex tensile structures and, at the same time, to reduce the defects that might occur due to the deformation of the elastic material. In this article, emphasis is given to the development of a custom-made end-effector tool, which is responsible to add elastic threads and create connections in the form of nodes. Based on additive fabrication logic, this process suggests the development of physical prototypes through a design optimization and tool-path verification.
