title	Impact of Using Structural Models on Form Finding - Incorporating Practical Structural Knowledge into Design Studio
source	Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 483-492
summary	Physical Models as an architectural design tool, had major effect on architecture learning process. In structural form finding, it helped in improving visual design thinking to track form creation processes during form finding design stage. The aim is to study the impact of using physical models for second year architecture students in design studios learning. By analyzing and comparing students’ performance and progress; to clarify the effect of using physical models as a tool for designing progression, followed by analytical study on the students' structural models, in order to investigate the influence of models on their design educational progress. Research achieved that there were three basic phases the students pass through during form finding process when used manual physical models that improve the students' design capability.

summary	The nature of the architectural design process can be described along the lines of the following representational devices: the plan and the model. Plans can be considered one of the oldest methods to represent spatial and aesthetic information in an abstract, 2D space. However, to be used in the design process of 3D architectural solutions, these representations are inherently limited by the loss of rich information that occurs when compressing the three-dimensional world into a two-dimensional representation. During the first Digital Turn (Carpo 2013), the sheer amount and availability of models increased dramatically, as it became viable to create vast amounts of model variations to explore project alternatives among a much larger range of different physical and creative dimensions. 3D models show how the design object appears in real life, and can include a wider array of object information that is more easily understandable by nonexperts, as exemplified in techniques such as building information modeling and parametric modeling. Therefore, the ground condition of this paper considers that the inherent nature of architectural design and sensibility lies in the negotiation of 3D space coupled with the organization of voids and spatial components resulting in spatial sequences based on programmatic relationships, resulting in an assemblage (DeLanda 2016). These conditions constitute objects representing a material culture (the built environment) embedded in a symbolic and aesthetic culture (DeLanda 2016) that is created by the designer and captures their sensibilities.

title	Modelling in Architecture - physical or virtual?
source	Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 135-144
summary	The use of models is one of the oldest media for creating, communicating and representing ideas throughout the ages. An investigation into the nature and characteristics of two modelling techniques in architectural design, i.e. physical and digital modeling, was conducted in the educational and professional domains in two countries. The aim of this study was to establish: (a) the degree of tangibility in model making as opposed to conventional and computational design approach; and (b) the iconic limitation of both types of modelling in design. To this end a survey was carried out among practising architects and students of architecture to establish their preferences and practices with respect to physical and virtual modelling. Some face-to-face interviews were conducted and an online questionnaire was distributed to both the aspiring and established architects. Data gathered through the questionnaire survey, interviews and photographs of the modelling process was analysed to come to tangible conclusions. Hence, this paper presents an insight into the merits and demerits of both the physical and virtual modeling techniques as seen through the eyes of professional and training architects.

title	vMESH : How to print Architecture?
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.394-398
summary	The use of 3D printing in architectural research, education and practice has been almost exclusively destined to produce physical representations – models— of designed building. Recent advances in Additive Manufacturing (AM) have exponentially increased the mechanical properties of 3D printed parts, opening new opportunities for this technology to be directly applied to functional architectural components at an increasingly larger scale. Thus, this paper examines the design, structural and aesthetic implications, as well as the feasibility of advanced 3D printing technologies in the production of functional architectural components through the design and prototyping of a customized, non-regular spatial frame system.

summary	The implications of architectural design decisions are in many cases hard to predict and envisage. As architectural tasks grow more complex and the design of architecture shifts away from the de- sign of end products towards the steering of dynamic processes, new ways of coping with complexity in the design and planning process are needed. Taking this as its starting point, as well as the need for ar- chitects to use familiar, established design tools, the CDP research group is working on new ways of supporting the design decision- making process with objective information so that designers are better able to manage these complexities. The focus of the group lies on di- rectly coupling interactive simulations and analyses with established design tools. This paper discusses a central problem in this context: how to present complex calculation results directly within a physical 3D-model. The approach described, as evidenced by the realized pro- totype, shows clearly that directly coupling real and digital infor- mation using interactive augmented visualization presents immense possibilities for managing the complexity of planning processes.

title	Sensory material architectures: Concepts and methodologies for spatial tectonics and tactile responsivity in knitted textile hybrid structures
source	International Journal of Architectural Computing vol. 14 - no. 1, 63-82
summary	As the knowledge of material computation advances, continuing the seamless integration of design and fabrication, questions beyond materialization can be addressed with a focus on sensing, feedback, and engagement as critical factors of design exploration. This article will discuss a series of prototypes, design methodologies, and technologies that articulate a textile’s micro-architecture, at the scale of fibers and stitches, to instrumentalize simultaneous structural, spatial, and sensory-responsive qualities. The progression of research displays an ever-deepening instrumentalization of fiber structure and its implications to form definition and responsivity, in creating form- and bending-active structures. The research results in a more refined definition of material behavior as the innate phenomena which emerge at the moment of textile fabrication. Ultimately, the architecture, in its materiality and physical, visual, and auditory responsivity, is designed to address specific challenges for children in filtering multiple sensory inputs, an underlying factor of autism spectrum disorder.

summary	This paper reports the responsive environments and the Theory of Ludification towards the interaction design using the structure of games on feedback process. It presents an interaction classification that can be reactive, responsive and dialogical based on authors related to cybernetics studies. It exposes the need for rationality in environments as an intrinsic and necessary condition for achieving the interaction. It also uses dialogue and game Vilém Flusser’s concepts to support this argument. Thus, it broadens the contemporary architectural discussion that encompassing communication processes that do not recognize the physical boundaries of the buildings.

title	Reality is interface: Two motion capture case studies of human–machine collaboration in high-skill domains
source	International Journal of Architectural Computing vol. 14 - no. 4, 398-408
summary	This article explores hybrid digital/physical workflows in the building trades, a high-skill domain where human dexterity and craft can be augmented by the precision and repeatability of digital design and fabrication tools. In particular, the article highlights two projects where historic construction techniques were extended through live motion capture of human gesture, information-rich visualization projected in the space of fabrication and custom robotic tooling to generate free-form running moulds. The first case study explores decorative plastering techniques and an augmented workflow where designers and craftspeople can quickly explore patterns through freehand sketch, test ideas with shaded previews and seamlessly produce physical parts using robotic collaborators. The second case study reimagines a roman vaulting technique that used terracotta bottles as part of an interlocking masonry system. Motion capture is used to place building elements precisely in material arrays with real-time visual feedback guiding the hand-held placement of each bottle. These case studies serve to underscore the emerging importance of reality capture in the design and construction of the built environment. Increasingly, the algorithmic power of computational tools and the nuances of human skill can be combined in hybrid design and fabrication workflows.

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 paper is part of a body of research developing an exploratory dialogue between the built form and the environment, via experimentation with performative geometry and material. Here, geometry is considered a design material with the specific capacity to contribute to the performative aspects and kinetic capabilities of building skins.This work opens with a review of emerging opportunities for architects to design materials. It then discusses the concept of Material Active Geometry (MAG) as a means of designing new properties for existing materials. This is followed by a discussion of MAG principles that inform the concepts of flexibility and rigidity in a 3D-printed textile called Flexible Textile Structure (FTS). This research characterizes two FTS types and discusses their potential to be employed in building skins; it also considers combinatory approaches to computational models and physical prototyping. The work concludes with a discussion of the advantages of using FTS, and provides a trajectory for future research in the field of responsive materials and systems.

summary	The complex nature of architecture requires often planning teams with specialists from multiple disciplines. Architectural education however, addresses this interdisciplinary modus operandi rarely. This paper presents the design and production process of a real world solar façade installation realized at the University of Kassel to illustrating the potentials of such an approach. Interdisciplinary teamwork allowed students not only to solve complex problems, but also to produce knowledge and to advance into design research. Student exploration resulted in a unique fabrication technique, combining tensile fabric and resin to facilitate the fabrication of multifunctional, monocoque shells; combining all necessary technical components in a single building element. This paper discusses the success of student collaboration and teaching strategies for key parts of the design process at different scales. Moreover, it highlights the importance of physical form-finding models and an analogue - digital workflow for collaborative communication. The Free Skin project offers both insight into applied use of interdisciplinary teamwork, and a proposal for incorporating such collaboration into architectural education.

title	Parametrically Fabricated Joints: Creating a Digital Workflow
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.412-417
summary	Timber joinery for furniture and architectural purpose has always been identified as a skill or craft. The craft is the demonstration of hand machined skill and precision which is passed down or developed through the iteration of creation and refined reflection. Using digital fabrication techniques provides new, typically unexplored ways of creating and designing joints. It is as if these limitations which bind the ratio of complexity and use are stretched. This means that these joints, from a technical standpoint, can be more advanced than historically hand-made joints as digital machines are not bound by the limitations of the human. The research investigated in this paper explores the ability to create sets of joints in a parametric environment that will be produced with CNC machines, thus redefining the idea of the joint through contemporary tools of creation and fabrication. The research also aims to provide a seamless, digital workflow from the flexible, parametric creation of the joint to the final physical fabrication of it. Traditional joints, more simple in shape and assembly, were first digitally created to ease the educational challenges of learning a computational workflow that entailed the creation and fabrication of geometrically programmed joints. Following the programming and manufacturing of these traditional joints, more advanced and complex joints were created as the understanding of the capabilities of the software and CNC machines developed. The more complex and varied joints were taken from a CAD virtual environment and tested on a 3-axis CNC machine and 3D printer. The transformation from the virtual environment to the physical highlighted areas that required further research and testing. The programmed joint was then refined using the feedback from the digital to physical process creating a more robust joint that was informed by reality.

title	Protocol of Error: The design and construction of a bending-active gridshell from natural bamboo
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. 415-424

summary	This paper advocates alternative methods to overcome the impossibility of realising ‘perfect’ digital designs. It discusses Hong Kong’s 2015 ‘ZCB Bamboo Pavilion’ as a methodological case study for the design and construction of architecture from unprocessed natu- ral bamboo. The paper critically evaluates protocols set up to deal with errors resulting from precise digital design systems merging with inconsistent natural resources and onsite craftsmanship. The paper starts with the geometric and tectonic description of the project, illus- trating a complex and restrictive construction context. Bamboo’s unique growth pattern, structural build-up and suitability as a bending- active material are discussed and Cantonese bamboo scaffolding craftsmanship is addressed as a starting point for the project. The pa- per covers protocols, construction drawings and assembly methods developed to allow for the incorporation and of large building toler- ances and dimensional variation of bamboo. The final as-built 3d scanned structure is compared with the original digital model. The pa- per concludes by discussing the necessity of computational architec- tural design to proactively operate within a field of real-world inde- terminacy, to focus on the development of protocols that deal with imperfections, and to redirect design from the virtual world towards the latent opportunities of the physical.

summary	The research builds on the relationship between matter and energy and the idea of boundaries as sentient interfaces capable of affecting our bodily experience and perception of space due to their inherent physical attributes. Two key issues addressed are firstly, the revisiting of the architectural boundary as a thermodynamic zone and secondly, the identification of material behaviour in relation to energy stimuli. It is argued that the transient behaviour of materials can offer an instrumental reconsideration on how architecture establishes spatial articulation through boundaries and this is demonstrated through a design-led project.

title	Printing Compound-Curved Sandwich Structures with Robotic Multi-Bias Additive Manufacturing
source	Proceedings of the 2023 DigitalFUTURES The 5st International Conference on Computational Design and Robotic Fabrication (CDRF 2023)
doi	https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_44
summary	A research team at Florida International University Robotics and Digital Fabrication Lab has developed a novel method for 3d-printing curved open grid core sandwich structures using a thermoplastic extruder mounted on a robotic arm. This print-on-print additive manufacturing (AM) method relies on the 3d modeling software Rhinoceros and its parametric software plugin Grasshopper with Kuka-Parametric Robotic Control (Kuka-PRC) to convert NURBS surfaces into multi-bias additive manufacturing (MBAM) toolpaths. While several high-profile projects including the University of Stuttgart ICD/ITKE Research Pavilions 2014–15 and 2016–17, ETH-Digital Building Technologies project Levis Ergon Chair 2018, and 3D printed chair using Robotic Hybrid Manufacturing at Institute of Advanced Architecture of Catalonia (IAAC) 2019, have previously demonstrated the feasibility of 3d printing with either MBAM or sandwich structures, this method for printing Compound-Curved Sandwich Structures with Robotic MBAM combines these methods offering the possibility to significantly reduce the weight of spanning or cantilevered surfaces by incorporating the structural logic of open grid-core sandwiches with MBAM toolpath printing. Often built with fiber reinforced plastics (FRP), sandwich structures are a common solution for thin wall construction of compound curved surfaces that require a high strength-to-weight ratio with applications including aerospace, wind energy, marine, automotive, transportation infrastructure, architecture, furniture, and sports equipment manufacturing. Typical practices for producing sandwich structures are labor intensive, involving a multi-stage process including (1) the design and fabrication of a mould, (2) the application of a surface substrate such as FRP, (3) the manual application of a light-weight grid-core material, and (4) application of a second surface substrate to complete the sandwich. There are several shortcomings to this moulded manufacturing method that affect both the formal outcome and the manufacturing process: moulds are often costly and labor intensive to build, formal geometric freedom is limited by the minimum draft angles required for successful removal from the mould, and customization and refinement of product lines can be limited by the need for moulds. While the most common material for this construction method is FRP, our proof-of-concept experiments relied on low-cost thermoplastic using a specially configured pellet extruder. While the method proved feasible for small representative examples there remain significant challenges to the successful deployment of this manufacturing method at larger scales that can only be addressed with additional research. The digital workflow includes the following steps: (1) Create a 3D digital model of the base surface in Rhino, (2) Generate toolpaths for laminar printing in Grasshopper by converting surfaces into lists of oriented points, (3) Generate the structural grid-core using the same process, (4) Orient the robot to align in the direction of the substructure geometric planes, (5) Print the grid core using MBAM toolpaths, (6) Repeat step 1 and 2 for printing the outer surface with appropriate adjustments to the extruder orientation. During the design and printing process, we encountered several challenges including selecting geometry suitable for testing, extruder orientation, calibration of the hot end and extrusion/movement speeds, and deviation between the computer model and the physical object on the build platen. Physical models varied from their digital counterparts by several millimeters due to material deformation in the extrusion and cooling process. Real-time deviation verification studies will likely improve the workflow in future studies.

title	Tangible User Interfaces for Teaching Building Physics: Towards continuous designing in education
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. 693-702
doi	https://doi.org/10.52842/conf.caadria.2016.693
summary	This paper follows our evaluation and research into designing tangible physical media for the purposes of teaching building physics to undergraduate architecture students. These media interfaces make use of a virtual environment to promote an understanding of the cycles, which govern architectural and urban projects (for example solar studies, the flow of heat, air and water). This project aims to create an ecology of devices which can be used by students to self-direct themselves and harbour critical making in their research methods (with the explicit intent of dissolving the barrier between design and research). The basic premise of this research, is that in light of growing student numbers, more students lacking confidence in numeracy skills as well as the desire to have self-directed or group-directed learning, tangible media has a promising role to play. There are several reasons for this optimism. The first is that a better sense of intuition is gained from an interactive model over reading notes from a lecture or textbook. The second is that tangible media engages in other modes of learning, being valuable to students who have an aptitude for kinesthetic and spatial learning over text-dominant learning.

summary	Lighting analysis tools have proven their ability in helping designers provide functional lighting, increase comfort levels and reduce energy consumption in buildings. Consequently, the number of lighting analysis software is increasing and all are competing to provide credible and rigorous analysis. The rapid adoption of parametric design in architecture, however, has resulted in complex forms that make the evaluation of the accuracy of digital analysis more challenging. This study aims to evaluate and compare the performance of daylighting analysis in two industry standard software (Autodesk Revit and 3ds Max) when analysing the daylighting of complex parametric façade patterns. The study has shown that, generally, both Revit and 3ds Max underestimate illuminance values when compared to physical scaled models. 3ds Max was found to outperform Revit when simulating complex parametric patterns, while Revit was found to outperform 3ds Max when simulating simple fenestration geometries. As a general conclusion, the rapid progress of parametric modelling, integrated with fabrication technologies, has made daylighting analysis of complex geometries more challenging. There is a need for more sophisticated algorithms that can handle the increased level of complexity as well as further verification studies to evaluate the accuracy claims made by software vendors.

title	Translating Digital to Physical Gradients

summary	As the practice of using notations to translate from two to three-dimensions is becoming superseded by the direct relaying of building information digitally, the separation between designing and building is diminishing. A key aspect in lessening further this divi- sion, is heterogeneous materiality that supersedes component thinking and effectively tectonics. Being an embodiment of the redundancies of tectonic assembly, a curtain wall detail has been redesigned with a heterogeneous and continuous multi-material using CFD. The main research problem following this redesign has been the conversion of material data from the CFD program into a 3D-printable format and in order to achieve a closer linkage between design and building. This has been pursued by initially converting the fused material parameters into fluid weight data and eventually into RGB colour values. The re- sulting configuration was output initially as a multi-colour print and effectively fabricated in a multi-material.
