summary	While new software interfaces are making the interaction between humans and robots more pedestrian, there is still an extremely complex workflow from the conception of data on the part of humans to the final action of the arm. In order to continue to promote and advance the use of these versatile tools in architecture, pedagogical strategies are needed to better enable users to engage with them quickly and obtain results while minimising frustration. This paper will outline a pedagogical strategy for introducing the multi-layered levels of knowledge and understanding required to operate a 6-axis robotic arm as developed in undergraduate architectural coursework. It will highlight the various learning modules created in order to deliver the necessary information for understanding the complex operational pipeline required to interact with and operate the robotic arm successfully.

title	Empirical Evaluation of Three Wind Analysis Tools for Concept Design of an Urban Wind Shelter
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 313-322
doi	https://doi.org/10.52842/conf.caadria.2015.313
summary	The aim of this investigation was to evaluate the performance of three wind analysis programs used in the early design stage (EDS) of a passive windbreak shelter concept for an urban context. This study compared the different workflows of these programs and the respective visualized results, identifying the differences and limitations of these tools, for design exploration. The programs tested were Autodesk Vasari, ODS-Studio, and ANSYS CFX. The results of this investigation indicate that basic computational fluid dynamics (CFD) programs such as Vasari was found to be more suitable for the observation of large-scale wind phenomena through the whole area of the shelter. Moreover, intermediate CFD tools (functions, usability) such as ODS-Studio can be used more efficiently in detailed visualization of wind interacting with design features. Finally, a more sophisticated CFD program like ANSYS CFX can be incorporated in the early design stage workflow for final verification of results.

title	Crowd Mapper: Projection-based Interactive Pedestrian Agents for Collective Design in Architecture
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 1, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 191-200

wos	WOS:000372317300020
summary	Crowd Mapper is a projection-based, low-cost spatial design tool that can visualize possible pedestrian crowd behaviors associated with spatial configurations that are interactively updated by users. The method utilizes efficient representation of 2-D silhouette-based figures using agent-based computation, developed by the first author, and allows real-time editing of building designs by multiple users. The use of projection mapping technology allows architects to project multiple design schemes with three-dimensional depth and qualities. While this method still conforms to the familiar framework of architectural production standards utilizing traditional white massing models, the method has a potential to improve the existing work flow and stimulate the creativity of architects by its real-time editing capabilities.

title	Effect of Pedestrian Observation Mode on Perceptual Continuity of the Streetscape
source	ENVISIONING ARCHITECTURE: IMAGE, PERCEPTION AND COMMUNICATION OF HERITAGE [ISBN 978-83-7283-681-6],Lodz University of Technology, 23-26 September 2015, pp.398-407
summary	The results of the experimental study revealed that the impacts from the building design and their layout differ according to observation mode of the pedestrian. This may imply that the regulation of building elements should not be considered in a rigid way but in more flexible according to given situation. Establishment of more reasonable and reliable design guideline that takes the observation mode into account should contribute to renew a part of a traditional neighbourhood smoothly while preserving original streetscape that people can feel usable and comfortable atmosphere.

source	The next city - New technologies and the future of the built environment [16th International Conference CAAD Futures 2015. Sao Paulo, July 8-10, 2015. Electronic Proceedings/ ISBN 978-85-85783-53-2] Sao Paulo, Brazil, July 8-10, 2015, pp. 242.
summary	During the past decade the implementation of energy harvesting sensor technology, at micro scale, has occurred due to the rapid growth of low-powered device usage, such as mobile phones, laptops, and the development of LED lights significantly increasing in efficiency. Studies have demonstrated that the ability of this technology to harvest energy from the human body, such as footfalls, can be used in the generation of electricity. Piezoelectric sensor technology has been investigated for this purpose, due to its significant advancement in the efficiency and its application in a variety of designs. This research investigates how pedestrians can become generators of their own service, through the use of piezoelectric sensor technology, in the form of safety lighting. Proposed urban design scenarios explore the opportunity implementing a piezo power-generating device along high traffic pedestrians pathways in the City of Melbourne (Australia), evaluating real time and storage options, considering harvesting the energy during the day and using it at night time when needed.

title	Panelisation With Sheet Metal Cladding On Free-Form Roof
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 713-722
doi	https://doi.org/10.52842/conf.caadria.2015.713
summary	This document shows a rationalisation method of sheet metal panelling on free-formed surfaces and a case study of it. Ichimonji-buki is a cladding method widely used in Japan for the roofs of traditional temples and shrines. It consists of sheet metal roofing with flat lock seams, allowing for minimal gaps along the joints. By integrating the characteristics of the flat lock joint and a dynamic relaxation analysis via computational modelling, continuous vertical seam lines can be realised while keeping panels almost identical in shape and with a limited number of variations. In the case study of Silver Mountain, the free-formed roof is clad with approximately 8,000 panels, out of which 92% are standardised and can be easily fabricated.

summary	The aim of this work is to try to set out how new technologies can influence the perception of a museum exposition. The problem which will be analysed is how to adapt an exhibition to the needs of visually impaired people. The problem will be considered on the basis of the case studies which were the part of an agreement between the Army museum in Bialystok and our Faculty. In traditional museums the main principle is the prohibition of touching exhibits.The project goal was to help blind people understand the features of the environment around them through the sense of touch. The novelty of this work is the study of how new digital technologies may improve the perception for the visually impaired.In the paper the method of 3D scanning, modelling and 3D printing will be presented. In conclusion the encountered problems and plans for further action will be discussed.

title	Toward a Behavioral Design System: An Agent-Based Approach for Polygonal Surfaces Structures
source	ACADIA 2105: Computational Ecologies: Design in the Anthropocene [Proceedings of the 35th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-53726-8] Cincinnati 19-25 October, 2015), pp. 161-172
doi	https://doi.org/10.52842/conf.acadia.2015.161
summary	The following research investigates the development of an agent-based design method as an integrative design tool for polygonal surface structures. The aim of this research is to develop a computational tool that self-organizes the emergence of polygonal surface structures from interaction between its constitutive lattices. This research focuses on the ethological level of morphogenesis that is relevant to the animal or insect societies, whereby agents mediate the material organizations with environmental aspects. Meanwhile, behavior-based approaches are investigated as a bottom-up system to develop a computational framework in which the lower-level features constantly interact. The lower-level features such as material properties (e.g., geometric descriptions) are abstracted into building blocks or agents to construct the agent’s morphology. The abstracted principles, which define the agent’s morphology, are aggregated into a generative tool to explore the emergent complexities. This exploration coupled with the generative constraint mechanisms steers the collective agents system toward the cloud of solutions; hence, the collective behaviors of agents constitute the polygonal surface structures. This polygonal system is a bottom up approach of developing the complex surface that emerges through topological and topographical interaction between cells and their surrounding environment. Subsequently, the integrative system is developed through agent-based parametric modelling, in which the knowledge-based system as a top-down approach is substituted with the agent system together with its morphological features and significant behaviors.

summary	The underlying thesis of the research described in this paper is that imaginative, model-based explorations may help us better understand iconic architectural artefacts, such as cultural heritage projects. In order to systematically consider and study architectural artefacts, it is essential for academics to reach a level of clarity – and potentially even consensus – concerning the domains of architectural design that may be considered relevant and to question - often implicitly – shared conceptions. This paper intends to communicate the results and findings of an in-depth case-based exploration on the basis of ten design artefacts, using a specially developed conceptual framework. Furthermore, the aim was to draw conclusions concerning the benefits and potentials of this approach in the context of heritage-based architectural research in an academic environment.

summary	Early design phase energy modelling is used to provide the design team with feedback about the impact of various building configurations. For better energy-conscious and sustainable building design and operation, the construction of BIM data interoperability for energy performance assessment in the early design phase is important. The purpose of this study is to suggest a development of BIM data interoperability for energy performance assessment based on BIM. To archive this, the authors have investigated advantages of BIM-based energy performance assessment through comparison with traditional energy performance assessment; and suggest requirements for development of Open BIM environment such as BIM data creation and BIM data application. In addition, the authors also suggested on BIM data interoperability system and developed mapping interface.

title	Performance-Based Parametric Design : A Framework for Building Envelope Design
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 603-612
doi	https://doi.org/10.52842/conf.caadria.2015.603
summary	Existing performance-based design exploration methods typically suffer from a lack of real-time feedback and a lack of actionable feedback. This paper proposes a hybrid design exploration method that overcomes these issues by combining parametric modelling, surrogate modelling, and evolutionary algorithms. The proposed method is structured as a mixed-initiative approach, in which parametric modelling is the key to creating a synergistic relationship between the architect and the computational system. Surrogate-based techniques will address the issue of real-time feedback, the evolutionary exploration techniques will address the issue of actionable feedback. As a first stage in developing the PEX method, this paper reports on two experiments conducted to identify an appropriate surrogate modelling technique that is efficient and robust.

doi	https://doi.org/10.52842/conf.caadria.2017.467
summary	Recent developments in Additive Manufacturing are creating possibilities to make not only rapid prototypes, but directly manufactured customised components. This paper investigates the potential for combining standard building materials with customised nodes that are individually optimised in response to local load conditions in non-standard, irregular, or doubly curved frame structures. This research iteration uses as a vehicle for investigation the SmartNodes Pavilion, a temporary structure with 3D printed nodes built for the 2015 Bi-City Biennale of Urbanism/Architecture in Hong Kong. The pavilion is the most recent staged output of the SmartNodes Project. It builds on the findings in earlier iterations by introducing topologically constrained node forms that marry the principals of the evolved optimised node shape with topological constraints imposed to meet the printing challenges. The 4m high canopy scale prototype structure in this early design research iteration represents the node forms using plastic Fused Deposition Modelling (FDM).

summary	The following paper provides reflections on the importance of analytical drawings in the process of understanding the architectural built heritage together with relevant aspects to analyse, theories and tools to produce them. The role of these graphic works is to analyse, document and communicate only a few aspects of the building. The main aim is to undertake an analysis through the use of one or more drawings representing the graphic translation of an analytical thought. The piece of writing presents a theoretical approach and examples of analytical drawings produced during previous researches, using CAD and 3d modelling software, to investigate some tangible and intangible characteristics of the architectural heritage.

summary	This article delineates the process of developing the project "Urbanimals" - an interactive installation designed and realised in Bristol, UK, in 2015. As the case study research, it draws attention to the difficulties in designing interactive structures in urban spaces - from an architects' idea to a construction stage. There are four areas that are being investigated: (1) Modelling interactions, (2) Negotiating locations and logistics, (3) Developing hardware and (4) Performing the on-site observations. The project draws from the idea of Smart City (SC) as the concept of the urban environment with a certain level of responsiveness through implementing a technology-driven matter that expands city offer perceivable, but gentle and not hindering way. It highlights the possible applications of projection technology and the utilisation of the 3D modelling software which provides complex tools for creating animations, movements and interactions with future users. The article gives clues how to design more engaging interactions and how to deal with implementing them in public realm.

title	Recapitulation in Generating Spatial Layouts

doi	https://doi.org/10.52842/conf.caadria.2015.199
summary	The noted 19th century biologist, Ernst Haeckel, put forward the idea that the growth (ontogenesis) of an organism recapitulated the history of its evolutionary development. While this idea is defunct within biology, the idea has been promoted in areas such as education (the idea of an education being the repetition of the civilizations before). In the research presented in this paper, recapitulation is used as a metaphor within computer-aided design as a way of grouping together different generations of spatial layouts. In most CAD programs, a spatial layout is represented as a series of objects (lines, or boundary representations) that stand in as walls. The relationships between spaces are not usually explicitly stated. A representation using Lindenmayer Systems (originally designed for the purpose of modelling plant morphology) is put forward as a way of representing the morphology of a spatial layout. The aim of this research is not just to describe an individual layout, but to find representations that link together lineages of development. This representation can be used in generative design as a way of creating more meaningful layouts which have particular characteristics. The use of genetic operators (mutation and crossover) is also considered, making this representation suitable for use with genetic algorithms.

summary	The AEC industry has been facing a digital transformation for improving services involved in buildings lifecycle, fostered by two disruptive technologies: Building Information Modelling (BIM) and Internet of Things (IoT). However, the literature lacks discussions regarding applications and challenges of BIM and IoT systems in the AEC. This Systematic Literature Mapping addresses this gap through search, analysis, and classification of 75 journal article abstracts published between 2015 and 2019. An increase of articles over the period is observed, predominantly with technical and processual solutions for Construction and Operation and Maintenance. The interoperability of data is a key challenge to organizations.

summary	A shape grammar-based computational system for chair design is presented. The paper focuses on the development of a methodology for modelling the definition stage of the design process. It is achieved by incorporating a specific grammar into a generic grammar to assist the designer in the convergence activities during the definition stage. Both grammars and their respective implementations were previously developed by different authors. The purpose is to enable the generation of a generic design solution that encompasses characteristics of a specific style, thus permitting subsequent exploration in the development stage.

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.

title	Subdivision Surface Modeling to Foster Responsive Design Solutions in an Integrated Multi-disciplinary Team

summary	This paper documents an architectural project developed using subdivision surface modelling. Subdivision surfaces are not new, and the tools are readily available in many 3d modelling applications. Despite their age and availability and recognised benefits they are rarely applied in architectural projects furthermore there is paucity of published case studies that demonstrate these tools in action. The second contribution to the field that this paper offers is in recognising the way in which subdivision surfaces can provide a new form of collaboration. Our core team consisted of architect, artist and 3d modeller and the project was inspired by a ceramic sculpture with unusual geometry. Subdivision surface modelling enabled a unique form of design exploration, feedback and communication between people with diverse skills. This case study therefore offers both insight into applied use of subdivision modelling and further depth into the way it enables interdisciplinary collaboration.

title	The Potential of Non-Manifold Topology in the Early Design Stages
source	ACADIA 2105: Computational Ecologies: Design in the Anthropocene [Proceedings of the 35th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-53726-8] Cincinnati 19-25 October, 2015), pp. 381-493
doi	https://doi.org/10.52842/conf.acadia.2015.381
summary	The importance of decisions made during the early design stages has prompted researchers to advocate the use of building performance simulation (BPS) during that stage. This paper investigates non-manifold topology (NTM) as a novel approach to 3D modelling that has the potential to be highly compatible with the early design stages and with the input requirements for BPS. The proposed approach avoids the process of simplifying polyhedral models produced by Building Information Modelling (BIM) software to conduct BPS. In particular, NTM allows for a clear segmentation of a building, unambiguous space boundaries, and perfectly matched surfaces and glazing subsurfaces. The NTM approach was tested through a software prototype that integrates 3D modelling software and an energy simulation engine.
