summary	Previous research (Bourdakis et al, 2012; Papasarantou et al, 2013) dealt with the problem of creating information visualisation systems capable of combining historical data of MUCIV's database and developing strategies that embed the non-spatial data in spatial models. The database was primarily designed as an experimental flexible spatio-temporal configuration of dynamic visual structures generating a variety of narrations through interaction.The attempt of producing a legible configuration driven by a number of criteria, led to the proposition of two different arrangements, namely the linear and radial array. The aim of this paper is to present the next step on the visualization after redefining both the way that thematic axes and data are visualized and arranged/scattered. Alternate configurations are investigated, based also on theoretical analysis on the conceptualization and perception of information visualization systems (Card et al 1999, Ware, 2004).

title	Sentient Concrete - Developing Embedded Thermal and Thermochromic Interactions for Architecture and Built Environment
doi	https://doi.org/10.52842/conf.caadria.2018.2.545

summary	Historically, architectural design focused on adaptation of built environment to serve human needs. Recently embedded computation and digital fabrication have advanced means to actuate physical infrastructure in real-time. These 'reactive spaces' have typically explored movement and media as a means to achieve reactivity and physical deformation (Chatting et al. 2017). However, here we recontextualize 'reactive' as finding new mechanisms for permanent and non-deformable everyday materials and environments. In this paper, we describe our ongoing work to create a series of complex forms - modular concrete panels - using thermal, tactile and thermochromic responses controlled by embedded networked system. We create individualized pathways to thermally actuate these surfaces and explore expressive methods to respond to the conditions around these forms - the environment, the systems that support them, their interaction and relationships to human occupants. We outline the design processes to achieve thermally adaptive concrete panels, illustrate interactive scenarios that our system enables, and discuss opportunities for new forms of interactivity within the built environment.

summary	Applying the method of "Land-Use Mix" (Amindabari et al. (2013)) and Focusing on changes in highly mixed land use areas within an extensive survey area and detailed analytical unit, the analysis in this study revealed some trends of distribution of mixed land use areas and their declining patterns in the eastern part of Saitama Prefecture, Japan. For example, among the changing land use patterns of Highly-Mixed-Points-as-of-1994, the pattern that a decreasing mixture index was associated with increasing residential land and decreasing commercial land occurred most often, and the points that changed with that pattern accounted for about 32% of all the Highly Mixed Points, and about 51% of the decrease in mixture index points.

title	Utilization of Simulation Tools in Early Design Phases Through Adaptive Detailing Strategies
doi	https://doi.org/10.52842/conf.caadria.2018.2.011

summary	Decisions taken at early stages of building design have a significant effect on the planning steps for the entire lifetime of the project as well as the performance of the building throughout its lifecycle (MacLeamy 2004). Building Information Modelling (BIM) could bring forward and enhance the planning and decision-making processes by enabling the direct reuse of data hold by the model for diverse analysis and simulation tasks (Borrmann et al. 2015). The architect today besides a couple of simplified simulation tools almost exclusively uses his know-how for evaluating and comparing design variants in the early stages of design. This paper focuses on finding new ways to facilitate the use of analytical and simulation tools during the important early phases of conceptual building design, where the models are partially incomplete. The necessary enrichment and proper detailing of the design model could be achieved by means of dialogue-based interaction concepts with analytical and simulation tools through adaptive detailing strategies. This concept is explained using an example scenario for design process. A generic description of the aimed dialog-based interface to various simulation tools will also be discussed in this paper using an example scenario.

title	Architects on architectural film and animation
doi	https://doi.org/10.52842/conf.caadria.2012.637
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 637–646
summary	As part of our inquiry about the practice of architectural film and animation and where it might go, this paper presents the results of interviews with architects on space, and on animation. We present their rich sense of space, and explain how they structure architectural film and animation. We found that architects wish to convey the subjective impact of design, but don’t know how to connect film editing techniques to architectural ends. Computational design could fill this gap with, for example, drag-and-drop editing patterns.

title	Sensing Material Systems - Novel Design Strategies
source	International Journal of Architectural Computing vol. 10 - no. 3, 361-375
summary	The development of new building materials has decisively influenced the progression of architecture through the link between built form and available material systems. The new generation of engineered materials are no exception. However, to fully utilise these materials in the design process, there is a need for designers to understand how these new materials perform. In this paper we propose a method for sensing and representing the response of materials to external stimuli, at the early design stage, to help the designer establish a material awareness. We present a novel approach for embedding capacitive sensors into material models in order to improve material performance of designs. The method was applied and tested during two workshops, both discussed in this paper. The outcome is a method for anticipating engineered material behaviour.

summary	This paper investigates through a review of the current literature on smart cities, reflecting different concepts across different political-social contexts, seeking to contribute to the establishment of a critical framework for smart cities development. The present work provides a review of the literature of 250 selected publications from four databases (Scielo, ScienceDirect, worldwide science, and Cumincad), covering the years from 2012 to 2018. Publications were categorised by the following steps: 3RC framework proposed by Kummitha and Crutzen (2017), the main political sectors of city planning, implementation strategies, computational techniques, and organisation rules. The information was analised graphically trying to identify tendencies along the time, and also, seeking to explore future possibilities for implementations in different political-social contexts. As a case of study, Australia and Brazil were compared using the proposed framework.

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	“Divide et Impera” to dramatically and consciously simplify design: The mental/instance path - How reasoning among spaces, components and goals
doi	https://doi.org/10.52842/conf.ecaade.2012.1.269
source	Achten, Henri; Pavlicek, Jiri; Hulin, Jaroslav; Matejovska, Dana (eds.), Digital Physicality - Proceedings of the 30th eCAADe Conference - Volume 1 / ISBN 978-9-4912070-2-0, Czech Technical University in Prague, Faculty of Architecture (Czech Republic) 12-14 September 2012, pp. 269-278
summary	In our times, in a complex and universal village where problems are intertwined and pervasive beyond our imagination, we need new approaches to deal with them – appropriately. In a previous work we highlighted the importance to reason ontologies: a ‘world’ f.i. a building – as a mental image – is not a Linnaeus’s classifi cation (structured set of entities) but a system (goals oriented set of classes) able to reasoning upon selectively chosen entities belonging to different Realms (ontology universes) (Fioravanti et al., 2011a). The general aim of our research– to be an effective aid to design – is to simulate wo/man as designer and user of designed spaces, hence how mental skill can be computably included in new tools able to tackle these problems. This paper is focused on the fi rst role: how actor-designers approach design problems and how the inference mechanism can help them and affect the design process. A ‘Building Object’ - the dual system of Spaces and Technology elements – is inferred in several ways according to different goals and the inference mechanism can, simulating human mental shortcuts, optimize thinking.

title	Architecture-Human-Machine (re)configurations - Examining computational design in practice
doi	https://doi.org/10.52842/conf.ecaade.2018.2.139

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.

summary	Based on the experience from EU project ARCHI21 (Hunter et al, 2011) and long-term commitment to research of architectural presentations and educational approaches to expert and non-expert public (i.e. Juvancic, Mullins & Zupancic, 2012), the paper aims to clarify the terms used in CLIL-architecture context, identify the variables that have, in practice so far, proven to infl uence the learning outcome and learning experience both in architectural and language sense, and systematize the findings into the useful system. The result can be envisioned as the potential ‘ladder of the CLIL & architecture integration‘. The system would be of help to anyone trying to integrate language learning at different stages of architectural education, pointing out the required fundamentals, predicting the possible learning outcomes or benchmarking them after the experience. The basic terms/variables divided into three major infl uencing groups - competence, work environment and course settings - are described first, proceeded with the scheme connecting them into the system and two actual examples ‘run’ through the matrix for illustrative purposes. The paper also looks specifi cally into the use of different immersive environments and digital communication tools for teaching the architecture/design–other language combination and adapts the system to this segment, while also briefly comments on learners and teachers responses to CLIL-architecture integration.

summary	The paper presents a future architectural detailing strategy enabled by the design of functionally graded materials (FGM). In specific, our proposal suggests the possibility of removing mechanical fasteners and adhesives from joint details. This is achieved by combining the principles of interlocking joineries found in traditional timber structures and current Multi-Material Additive Manufacturing (MMAM) technology to materialise FGMs. FGM belongs to a class of advanced materials characterised by variation in properties as the dimension varies by combining two or more materials at a microscopic scale (Mahamood et al. 2012). FGM is ubiquitous in nature and, when properly designed, can exhibit superior performance characteristics compared to objects comprised of homogeneous material properties. With the aim of developing interlocking details with improved performance, reliability, and design flexibility, we focus on controlling material stiffness, joint fitting, and geometry through the design of the microscopic material layout. A case study design will be presented to illustrate the process.

title	Multi-criteria evolutionary optimisation of building enveloped during conceptual stages of design
doi	https://doi.org/10.52842/conf.caadria.2012.497
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 497–506
summary	This paper focuses on using evolutionary algorithms during conceptual stages of design process for multi-criteria optimisation of building envelopes. An experiment is carried out in optimising a panelled building envelope. The design scenario for the experiment is based on the scenario described in Shea et al. (2006) for the building envelope of the Media Centre Building in Paris. However, in their research, the optimisation process only allowed panel configuration to be optimised. In this paper, the task is to approach the optimisation of the envelope of the same building, assuming it to be in the early phases of the design process. The space of possible solutions is therefore assumed to be much wider, and as a result both external building form and internal layout of functional activities are allowed to vary. The performance intent of the experiment remains the same as that of Shea et al. (2006), which was to maximise daylight and minimise afternoon direct sun hours in the building at certain specific locations.

title	Robotic Construction by Contour Crafting: The Case of Lunar Construction
source	International Journal of Architectural Computing vol. 10 - no. 3, 423-438
summary	Contour Crafting is a digitally controlled construction process invented by Professor Behrokh Khoshnevis that fabricates components directly from computer models, using layered fabrication technology. By obviating the need for formwork used in traditional concrete construction, CC can reduce costs and construction times significantly. The technique has great potential as a robotic form of construction reliant on relatively minimal human labor as a form of construction in relatively hazardous environments, such as the Moon with its radiation levels that can prove highly damaging. Current research funded by NASA has been exploring the potential for using CC on the Moon to build structures making use of readily available regolith that is found in great abundance on the surface of the Moon. This article offers an overview of this research and evaluates the merits of using CC on the Moon.

title	Potential Use of Structural Layout Optimization at the Conceptual Design Stage
source	International Journal of Architectural Computing vol. 10 - no. 1, 13-32
summary	Despite recent developments in computer-aided design in architecture, both in terms of form generation techniques and performance-based design tools, there still appears to be polarization between the ‘visual’ and the ‘technical’ elements of design. Two causes of this are discussed: long-standing tradition within the discipline and perception of design as primarily a visual exercise. Structural layout optimization is a technique which enables automatic identification of optimal arrangements of structural elements in frames. As the technique appears to have the potential to help reduce the polarization between the visual and the technical elements of design, it can be considered as an ‘integrative’ form generation tool. Applications of the technique are considered via three design examples, demonstrating both its potential and areas where refinement is required before it is suitable for application in practice.

title	Urban Morphology and Solar Incidence in Public Spaces - an Exploratory Correlation Analysis Through a CIM System

summary	The walkability of open spaces has been highlighted in current discussions about the production of designed environments in urban contexts (Matan, 2011). To contribute to this theme, this work selects the environmental comfort of open spaces as its element of study. The production of urban space was investigated, specifically in regard to urban morphology, understanding that city design directly influences environmental comfort (Jacobs, 1996). This work addresses the geographic context of low latitudes, specifically in hot and humid climate zones of Brazil, and, in this context, according to NBR 15220 (national performance standards), shading is one of the main comfort strategies, so solar incidence was the approached environmental phenomenon. Thus, this work presents a digital system that performs exploratory analysis on the correlations between urban form indicators and environmental performance indicators, specifically solar incidence. The method consists of three steps: urban form modeling (1), indicator measurement (2) and correlation analysis (3). In the first stage, different spatial sections of a city in Brazil were represented in the digital environment (1). This work’s implementation instrument is based on a City Information Modeling framework (Beirao et al., 2012). Visual Programming Interface (VPI) and Geographic Information Systems (GIS) tools were used, in addition to a Relational Database Management System (RDBMS). Then, for each urban clipping, the values of morphological indicators and the incidence of solar radiation were measured (2). Based on the values of the indicators, an exploration of their correlation was carried out by statistical methods (3). The results of the correlation analysis and their correspondent scatter plots are presented. Finally, possible applications of the results for the creation of prescriptive urban planning systems are discussed, seeking to promote a sustainable urban environment.

Online and Global. 24-30 October 2020. edited by B. Slocum, V. Ago, S. Doyle, A. Marcus, M. Yablonina, and M. del Campo. 340-349.
summary	This paper presents the design, control system, and elastic behavior of ELAbot: a robotic bending active textile hybrid (BATH) structure that can self-form and transform. In BATH structures, equilibrium emerges from interaction between tensile (form active) and elastically bent (bending active) elements (Ahlquist and Menges 2013; Lienhard et al. 2012). The integration of a BATH structure with a robotic actuation system that controls global deformations enables the structure to self-deploy and achieve multiple three-dimensional states. Continuous elastic material actuation is embedded within an adaptive cyber-physical network, creating a novel robotic architectural system capable of behaving autonomously. State-of-the-art BATH research demonstrates their structural efficiency, aesthetic qualities, and potential for use in innovative architectural structures (Suzuki and Knippers 2018). Due to the lack of appropriate motor-control strategies that exert dynamic loading deformations safely over time, research in this field has focused predominantly on static structures. Given the complexity of controlling the material behavior of nonlinear kinetic elastic systems at an architectural scale, this research focuses on the development of a cyber-physical design framework where physical elastic behavior is integrated into a computational design process, allowing the control of large deformations. This enables the system to respond to conditions that could be difficult to predict in advance and to adapt to multiple circumstances. Within this framework, control values are computed through continuous negotiation between exteroceptive and interoceptive information, and user/designer interaction.

title	Point Cloud Segmentation for Building Reuse - Construction of digital twins in early phase building reuse projects
doi	https://doi.org/10.52842/conf.ecaade.2023.2.327
source	Dokonal, W, Hirschberg, U and Wurzer, G (eds.), Digital Design Reconsidered - Proceedings of the 41st Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2023) - Volume 2, Graz, 20-22 September 2023, pp. 327–336
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. In this paper, various ML approaches, among others KPConv Thomas et al. (2019), ShapeConv Cao et al. (2021) and Mask-RCNN He et al. (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.

title	The Agency of Responsive Envelopes: Interaction, Politics and Interconnected Systems
source	International Journal of Architectural Computing vol. 10 - no. 3, 377-400
summary	This article positions the territory of responsive envelopes within the context of contemporary disciplinary questions surrounding the politics of the architectural envelope on one hand, and the agency of material explication of environmental, social and spatial performance on the other. Two recent prototype-based responsive envelope projects undertaken by the authors, the Stratus Project and Resonant Chamber, are described in detail relative to the reciprocity between the development of their materiality, form, production methods and their dynamic interaction with external forces, environments and inhabitants. An argument is made that responsive envelopes, in their capacity to structure continually evolving energetic, material and information exchanges between humans, buildings and the wider environment, have the potential to actively construct and enable political participation through spatial transformation, data driven processing and informatics. These envelopes are positioned as agents within wider ecologies and social systems, and as sites for the design of robotic architectures to engage such questions.

title	Custom Digital Workflows: A New Framework for Design Analysis Integration
source	International Journal of Architectural Computing vol. 10 - no. 4, 481-500
summary	Flexible information exchange is critical to successful design-analysis integration, but current top-down, standards-based and model-oriented strategies impose restrictions that contradict this flexibility. In this article we present a bottom-up, user-controlled and process-oriented approach to linking design and analysis applications that is more responsive to the varied needs of designers and design teams. Drawing on research into scientific workflows, we present a framework for integration that capitalises on advances in cloud computing to connect discrete tools via flexible and distributed process networks.We then discuss how a shared mapping process that is flexible and user friendly supports non-programmers in creating these custom connections. Adopting a services-oriented system architecture, we propose a web- based platform that enables data, semantics and models to be shared on the fly.We then discuss potential challenges and opportunities for its development as a flexible, visual, collaborative, scalable and open system.
