summary	This work-in-progress paper explores the opportunity to rethink the relationships architecture has with the environment and human behavior. Adaptive systems are gaining traction in the discourse as relationships between the built environment, the natural environment and its users evolve over time. This project, Pneuma-Technics, investigates pneumatic methods in the built environment, composite materials and components, computation, physical computing and sensory actuation. The objective is to advance a developing typology of responsive systems: a breathing architecture that is sensitive to its changing environment. Pneuma-Technics is actuated breath in built form - pneuma, the Greek word for “to breath,” and technics, the Greek word for technique/craft in art. The project imagines the potentials of a soft, interactive surface that allows for the passage of light, air, and human vision, yet maintains enclosure and insulation as necessary for architectural performance. These innovations project new futures onto traditional methods of architectural production and engage in nontraditional materials to develop unique environments. Pneuma-Technics’ is a body of research that consists of tangible experiments for the advancement of soft environments. However, we design for these potential futures as materials, methods, and collaborative action evolve the discourse toward adaptive technologies.

title	Identity and Image of Productive Spaces in the Process of Reuse

summary	In the transformation of industrial ruins – machine-buildings belonging to a relatively recent past – the dichotomous processes of change and preservation allow to reinterpret the design action as the intrusion of a new life. In the projects for the reuse and recycling of productive heritage, the delicate balance between the safeguard of the identity and the updating of the image to the changing contemporary needs may be declined through the notions of novelty and originality in architecture. The concept of originality – meant as an original re-reading of the pre-existences – can produce novelty as a new spatial interpretation, capable of generating an authentic innovation even just through limited interventions. Two projects of transformation for productive buildings – both partly realized – may act as research media to describe this transition: ever since the first life of these buildings has been unequivocally concluded, their ruins have become an integral part of the landscape, standing in a state of waiting and calling for projects able to insufflate a second life within them.

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	Toward a Behavioral Design System: An Agent-Based Approach for Polygonal Surfaces Structures
doi	https://doi.org/10.52842/conf.acadia.2015.161
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
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	Computation, in the context of a digital designing process, is redefining architectural practice. Architects are developing new sets of tools which are dramatically changing the typical way of design procedure. The paper describes the research assumptions, problems and solutions proposition, aimed at creation of a real-time form finding tool for architects based on engineering methods. Through intersecting architectural form evaluation with engineering analysis and optimisation tools it is highly intended to offer the opportunity to variety of architects and designers to use the exceedingly complex and compound process for their design improvement. The form finding tool, to be effective and reliable, has to provide immediate feedback to a designer. This requirement enforces a software developer to use more sophisticated solutions. The paper focuses on possibilities of already known engineering procedures acceleration such as Finite Element Method or Topology Optimization for effective implementation in architectural design process.

title	Performance-Based Parametric Design : A Framework for Building Envelope Design
doi	https://doi.org/10.52842/conf.caadria.2015.603
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
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.

summary	This paper presents an Augmented Reality application intended to establish a link to site history, approaching cultural heritage issues simulating the metaphor of time tunnel. It presents an initiative to bring technology to the end user, in order to rescue the past through AR of a plaza with cultural importance that suffered intervention with time. The work was developed as an exercise of a Virtual Reality class in a Graduate Program. The class exercise involved understanding uses of AR, development of AR applications and user perception of the built environment through the augmented lenses provided by AR applications. The method proposed for the exercise was the field study developed in seven steps: AR scope definition, preliminary exploration, AR application formulation, data collection and user perception evaluation. Four AR applications were developed and evaluated: 360 panorama and an overlap image, 3D object, and video with historic information. On site, users demonstrated surprise with the experiment and no difficulty of use, however transposition to the significant record of a past time varied with AR application and simplification of implementation.

title	Development of A Kinematic Physical Model for Building Volume Simulation
doi	https://doi.org/10.52842/conf.caadria.2015.241

summary	Both a physical model and VR are three-dimensional expression tools to enable intuitive understanding; however, both have pros and cons. Thus, this research took up the challenge of developing a kinematic physical model system for volume simulation of buildings or a city by using a physical model and VR data integrally. The developed system consists both of hardware which packed 105 lifting rods into a grid (the height of the rods could be changed individually by stepper motors) and of software which calculated the height of each rod from the VR data and lifted the rods. Through conducting verification experiments on the prototype system, a physical urban model could be produced in about two minutes, within acceptable error limits. In conclusion, the proposed method was evaluated as feasible and effective.

summary	With an exponential increase in the possibilities of computation and computer-controlled fabrication, high density information is becoming a reality in digital design and architecture. However, construction methods and industrial fabrication processes have not yet been reshaped to accommodate the recent changes in those disciplines. Although it is possible to build up complex simulations with millions of particles, the simulation is often disconnected from the actual fabrication process. Our research proposes a bridge between both stages, where one drives the other, producing a smooth transition from design to production. A particle in the digital domain becomes a drop of material in the construction method.The architect's medium of expression has become much more than a representational tool in the last century, and more recently it has evolved even beyond a series of rules to drive from design to production. The design system is the instruction itself; embedding structure, material and tectonics and gets delivered to the very end of the construction chain, where it gets materialised. The research showcased in this paper investigates tectonic systems associated with large scale 3D printing and additive manufacturing methods, inheriting both material properties and fabrication constraints at all stages from design to production. Computational models and custom design software packages are designed and developed as strategies to organise material in space in response to specific structural and logistical input.Although the research has developed a wide spectrum of 3D printing methods, this paper focuses only on two of the most recent projects, where different material and computational logics were investigated. The first, titled Filamentrics, intends to develop free-form space frames, overcoming their homogeneity by introducing robotic plastic extrusion. Through the use of custom made extruders a vast range of high resolution prototypes were developed, evolving the design process towards the fabrication of precise structures that can be materialised using additive manufacturing but without the use of a layered 3D printing method. Instead, material limitations were studied and embedded in custom algorithms that allow depositing material in the air for internal connectivity. The final result is a 3x2x2.5m structure that demonstrates the viability of this construction method for being implemented in more industrial scenarios.While Filamentrics is reshaping the way we could design and build light weight structures, the second project Microstrata aims to establish new construction methods for compression based materials. A layering 3D printing method combines both the deposition of the binder and the distribution of an interconnected network of capillaries. These capillaries are organised following structural principles, configuring a series of channels which are left empty within the mass. In a second stage aluminium is cast in this hollow space to build a continuous tension reinforcement.

summary	The non-standard approach, widely discussed in the past years as Architecture progressively uses alternative design methods different from the Euclidean paradigm, has allowed architects to transform the way architecture is conceived and materialized. Such evolution uses computer-aided design along with automation in production to originate the environment for the aided architectural conception field in which we present a method, in its early development stage, intended to create non-standard walls and envelopes based on cellular patterns using wood as base material. We present the results obtained from modeling and building two full-scale prototypes of non-standard wooden walls.

title	Remarks on Transdisciplinarity as Basis for Conducting Research by Design Teamwork in Real World Context through Two Case Studies of Algorithm Aided Lighting Design

summary	The definition of Research by Design (RD) as a research methodology is not yet well established. RD takes its position not only as a research method next to the 'traditional' sciences but also in relation to the creative design practice, where transdicsiplinarity is in essential role. Rather than defining architecture being transdisciplinary in itself, we see beneficial to conduct research together with various disciplines concerning the complexity of the life-world. Also in this interdisciplinary research group we are willing to hold on the designerly way of knowledge production. Of our practical experience working in an interdisciplinary research group shared values, research project management together with participation with evaluative aims were the most challenging aspects. At its best, attempt for genuine transcdisciplinarity was beneficial and rewarding, though sometimes challenging. We would like to target the discussion how we architects, as researchers identify in an interdisciplinary research group conducting transdisciplinary research.

title	Optimisation for Sport Stadium Designs
doi	https://doi.org/10.52842/conf.caadria.2015.573
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. 573-582
summary	Applying computational optimisation tools for sport stadium designs has become common practice. However, optimizations often occur only on a macro level (analysing stadium as a whole) and not on a micro level (a view from each seat). Consequently, items on a micro level with design details like guardrails can be overlooked, leading to financial losses for operators. Hence, the research argues that every seat is encouraged to have a clear field of view to avoid financial complications. In order to address this problem the research team developed and evaluated a script that allowed importing an existing design into Rhino. Firstly, the script evaluates the view of each seat via a colour coded response system. Secondly, the designer can select the respective seat, and view the sightline from the occupant’s sightline to various spots on the field to analyse where the obstruction is occurring. This ‘binocular view’ enables the designer to evaluate blind spots from each seat prior to project completion. As the script allows the designer to automate the micro level analysis, the research arguably provides a significant improvement for stadium design by comparing the time used for a design optimisation in a conventional method with the automated one.

summary	The aim of the research presented in this paper is to provide an additional method and tool for architects and designers as well as students and scholars to analyze the degree of complexity of a design. Fractal analysis (box counting) e.g. is one of these methods already used in architecture to measure the degree of complexity of an architectural design, for example of the elevation of a building. The method of semi-automated gradient-analysis described here focuses on the repetition of gradients and thus of proportion-repetition in a given design as one of several aspects of complexity reduction by redundancy.

summary	In this paper, we propose a method of generating schematic diagrams from 3D models of mechanical, electrical and plumbing (MEP) systems in order to represent this information in a more traditional, user-friendly format. It can be difficult to grasp the relationships between various MEP elements in building information models (BIM) because they are represented in a visually complex, three-dimensional manner. On the other hand, the relationships between building elements can be easily understood when using traditional schematic diagrams. First, sets of connected elements are extracted from a 3D model of MEP elements using their connection properties. Next, various elements of these systems are identified as nodes and their connections are represented as edges. Finally, these systems are displayed as a schematic diagram using element attribute information.

title	Perceived Emotional Effects of Digital Pattern in Façade Design
doi	https://doi.org/10.52842/conf.caadria.2015.623
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. 623-630
summary	This study raises the question of what the emotional significance of the digital patterns has and attempts to provide an answer to such a question. The purpose of this study is to propose a direction to effectively support the façade designs of buildings by understanding the emotive design characteristics of the patterns. This study explains the design patterns on façade designs. There are five types of digital patterns which include applied patterns, perforated patterns, layered patterns, cast patterns, and tiled patterns. Among those patterns, perforated patterns are focused in further detail. This study deals with identifying emotional effects of perforated design patterns. The emotional word ‘asymmetrical’ and ‘irregular’ shows the high average of the emotional value. In the bipolar adjectives, the high emotional value is ‘irregular-regular’ and ‘asymmetrical-symmetrical’. Therefore, the final design characteristics of the perforated patterns are ‘regularity’ and ‘symmetry’. This means to be able to use the perforated patterns in order to be perceived a building façade design as the regular and symmetrical emotional effect. In this paper, it is worth analyzing design characteristics of a building façade by the support of the digital technologies and discussing the utilization of design characteristics derived. This study has contributed to the process and method of deriving the analysis results.

title	Poisson's Ratio Material Distributions
doi	https://doi.org/10.52842/conf.caadria.2015.735
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. 735-744
summary	The Poisson’s ratio of materials describes the ratio of the transverse to axial strain. While most materials exhibit non-negative Poisson ratio, here we focus on the topological properties of negative ratio materials also known as auxetic constructs. Digital modelling and physical fabrication are employed to generate and test experimental auxetic configurations. The first set of studies employ 2D space-filling tessellations integrating both negative and positive Poisson ratio cells. The tessellations are designed through binary state transitions and gradual morphing transitions. A second set of studies explores the topological optimization of a single negative Poisson cell configuration following the logic that a cell constitutes the building block of auxetic materials. The third set of studies focuses on the translation of heterogeneous Poisson ratio 2D tessellations into 3D constructs. Here, two methods of fabrication are explored: lamination method and cellular grading. The precision of the cellular grading method renders it particularly suitable for multi-material 3D printing fabrication which is theoretically studied and proposed. Space-filling heterogeneous tessellation studies are applied to architectural and product design proposals. These proposals exhibit properties that could serve to design and develop further research on real-world applications.

summary	This study focuses on developing three-dimensional solar panels, as an alternative to traditional flat Photovoltaic (PV) surfaces in Building Integrated Photovoltaic (BIPV). We propose to increase the energy efficiency of buildings by using the entire envelope for energy production as well as by increasing the efficiency of solar energy output in orientations which were traditionally considered as non-ideal. The panels are constructed from Polycarbonate with integrated flexible photovoltaic film, solar paint or dye. The methodology included digital algorithm-based tools for achieving optimized variable three-dimensional surfaces according to local orientation and location, computational climatic simulations and comparative field tests. In addition, the structural, mechanical and thermal properties of the integration between flexible PV sheets and hard plastic curved panels were studied. Interim results demonstrate a potential improvement of 50-80% in energy production per building unit resulting from geometric variations per-se. The dependence of energy production by surface geometry was revealed and an optimized method for solar material distribution on the surface was proposed. A parametric digital tool for automatic generation of optimized three-dimensional panels was developed together with a database and material models of the optimized panels system.

summary	C-LITH is the reconsideration of the architectural building unit through the exploration of new composite techniques and materials. Our project develops individual compo- nents that exploit the strength, lightness, and variability possible with carbon ber laments when paired with computation, digital fabrication, and hand assembly. Traditionally, architectural units made of brick or concrete are small and multiple, heavy, dif cult to vary, and are much better in compression than tension. Using carbon ber laments to create variable units allows for larger individual units that can vary in both shape and structural performance as needed. Our units, developed through winding pre-preg carbon ber tow around disposable molds, bene t structurally from the quasi-isotropic properties that are developed through the winding patterns. The specific structural capacities of the units remain to be understood through further testing and analysis, which falls outside the scope of this current research. At this junction, structural capacities have been determined empirically, i.e. will it stand? Most importantly, as a formal study, our units address the use of carbon ber at the scale of architectural production. A majority of the effort involved in materializing C-LITH was the development of a two-fold prototypical manufacturing process that produces the components and assembly. For this we invented a method to quickly and cheaply construct variable cardboard molds that could withstand the wound casting and baking steps, but could also be easily weakened through water immersion to be removed. For the assembly we developed a rigid dummy-jig system to hold the joint plates in position with a high level of precision but could also incrementally absorb the adjustment errors unavoidable in hand assembly systems. Using a simple pin connection the resultant structures can be easily disassembled for transportation and reassembly elsewhere.

summary	With the rapid development of the digital fabrication technology, structural performance based design shows broad application prospects. Based on the research project "Reverse rafter", this paper aims to explore the possibility of simulating and re-applying Chinese traditional wood tectonics with structure performance based computational technology. Taking "eaves rafter" as research prototype, this project employed topology optimization as research method and “Millipede” as analysis tool. Through the comparison between the analysis results of traditional structure calculation and topology optimization method, this project revealed the underlying structural principles of "eaves rafter", based on which a modern reciprocal structure installation was generated through digital design method. CNC cutting technology was employed to ensure the fabrication accuracy in digital fabrication processes.

summary	The process of design and fabrication involves a complex cognitive activity, in which the human brain is part of a larger cognitive system that encompasses brain, body, tool, material and environment. In this system the cognition resides in the interaction of all these elements one with another in different stages of a design and making activity. This paper investigates the intermediary role of digital fabrication machines in changing the discourse of design cognition in relation to the action of making, inquiring into the diverging path from traditional craftwork. This research is shaped around the concept of transparent machine tools for an interactive participation in the process of design-making, shaping a human-machine interaction to unify the design and fabrication process.
