title	Fluid Morphologies: Hydroactive Polymers for Responsive Architecture
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. 478-487

summary	This paper describes Hydroactive Polymers (HAPs), a novel way of combining shape-changing Electroactive Polymers (EAPs) and water for potential design and architectural explorations. We present a number of experiments together with the Fluid Morphologies installation, which demonstrated the materials through an interactive and sensory experience. We frame our research within the context of both material science and design/architecture projects that engage the unique material properties of EAPs. A detailed description of the design and fabrication process is given, followed by a discussion of material limitations and potential for improving robustness and production. We demonstrate fluid manipulation of light and shadow that would be impossible to achieve with traditional electromechanical actuators. Through the development of this new actuator, we have attempted to advance the accessibility of programmable materials for designers and architects to conduct hands-on experiments and prototypes. We thus conclude that the HAP modules hold a previously unexplored yet promising potential for a new kind of shape-changing, liquid-based architecture

title	Translating Digital to Physical Gradients
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. 589-598

summary	As the practice of using notations to translate from two to three-dimensions is becoming superseded by the direct relaying of building information digitally, the separation between designing and building is diminishing.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.

title	Integrating CFD and VR for indoor thermal environment design feedback
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. 663-672

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

title	Breathing skins for wind modulation through morphology
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. 219-228
doi	https://doi.org/10.52842/conf.caadria.2016.219
summary	This study aims to investigate the design power to manipu- late the behaviour and characteristics of air through geometrical ma- nipulation of building skins. The simple cubic cells in the global sys- tem of a porous screen were manipulated to investigate the impacts of screen’s morphology on the air movement pattern within and around it. The results we discovered from the evaluation of several screen systems revealed trends in response to the careful manipulation of ef- fective shape parameters within a designed matrix of variations as a Matrix of Possible Effective Typologies (MPET). In this research, the main principles of framing the initial matrix were based on: a) Creat- ing pressure differences across the screens as a result of surface intru- sion and extrusion compositions. b) Changing the nature of the airflow (velocity and turbulence variation) with geometrical manipulations of the inlet and outlet of the screens’ components. Experimental and nu- merical studies were undertaken in parallel including the use of a wind tunnel with very smooth flow with precision wind sensors and the numerical studies by Computational Fluid Dynamics. The aim of this paper is to present part of the empirical investigations to demonstrate the power of geometry in shaping the air patterns, altering pressure and velocity through geometrical modification of porous surfaces for future applications.

title	Architecture of Intermodal Complex

summary	This paper focuses on the conception and design of architecture as the work of producing media about buildings and other environmental artifacts. I approach the questions regarding simplicity and complexity through "interdependence" and "intermodality." I believe the two concepts offer more precise frames of relations and contexts involving simplicity and complexity. I will first discuss the complexity as a condition of interdependences and how today's interdependences may provide a framework to understand complexity. I will then propose that intermodality adds to interdependence a notion that specifically pertains to today's media-driven culture and its complexity. I will next discuss how dependences and modalities are interconnected at various levels and eventually producing a new kind of semiosis that results from the disjunction between the medium and the content. I will in conclusion propose a new concept "apparatization" driven by interdependence and intermodality and how it changes shape and remain fluid, rather than scaling between simplicity and complexity, without a specific physical locus.

title	Development of educational-use computational fluid dynamics programming environment and workshop
source	International Journal of Architectural Computing vol. 14 - no. 2, 119-130
summary	In the current computer-aided architectural design education, students do not necessarily need to be taught to use more digital tools, but need to be introduced to the possibilities of designing their own digital tools. Designing the original tools with the assistance of educational-use environment for computational fluid dynamics programming improves the capability of the students to estimate the flows around architectures based on the mathematical background and the actual program. The authors have developed Educational Library for Fluid as an educational-use environment for computational fluid dynamics programming and ran the workshop where the students majoring in computer-aided architectural design tried to design computational fluid dynamics tools with Educational Library for Fluid. In this article, the details of Educational Library for Fluid and the results of the workshop are being reported. In addition, the key points of computational fluid dynamics education that the authors learned through the experience of the workshop are shared.

title	Parametric 3d wind loading on hemispheric dome structures
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.638-644
summary	Within the visual programming platforms in parametric design, it has not yet available with effective integration the CFD (Computational Fluid Dynamics) simulation systems. This coupling would be particularly useful in relation to the modeling of structures subjected to wind loads in a parametric and algorithmically programmed scenario. It is proposed in this work a parametric modeling of the distribution of wind loads on the surface of a hemispherical dome structure surface. From a combination of wind speed, internal and external pressure coefficient, dimensions of the building, topography and roughness of the terrain. It were defined the magnitude and direction of a field of distributed normal forces on the surface of the hemispherical dome and some results were obtained.

title	Toward the wind-related building performative design
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 109-218

summary	The integration of optimization algorithms and building performance simulation tools make it possible to carry out performa- tive design or performance-driven design, which aims to guide the de- sign synthesis process of the simulation results to continuously im- prove the design. However, the associated research work of wind- related building performance is still deficient, resulting from lack of applicable interface and the time consumption. Meanwhile, in the in- dustrial design realm, the aero-dynamics or fluid-dynamics behaviour of the production under development has been vastly analysed and op- timized based on the multi-discipline optimization (MDO) techniques. Owing to offering numerous built-in interface and integrated optimi- zation algorithm, MDO application software has begun to be used in building optimization design with the complex relationship between various objectives. With the advantage of MDO tools and aimed to provide an efficient optimization approach from the perspective of ar- chitect, this paper proposes a wind-related building performance op- timization design system integrating Rhinoceros and Fluent based on iSIGHT - a MDO application software. In addition, the lighting per- formance is considered in this research as well for implementing the multi-objective optimization. Two case studies of tall building optimi- zation design based on varied generative approaches are introduced to investigate the effect and efficiency of this system.

title	Physical and numerical simulation as a generative design tool
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. 353-362

summary	Environmentally sound and high-performance buildings are contributing towards a sustainable future. With increased density of contemporary urban space and the urgent desire to promote building performance, a better understanding of wind behaviour will positively influence future design explorations. In the traditional sequential ar- chitectural practice, there is a gap between design and performance simulation. This paper presents an experimental and systematic study of the performance-oriented design tools, strategies and workflows utilized in the concept prototyping of a high-rise building. It describes a new approach to incorporate wind tunnel testing, computational flu- id dynamics simulation as well as parametric software, sensors and open-source electronics platform into an accessible, interactive and low-cost form generation kit, rapidly evaluating the performance of potential design options in the early design stage. As indicated in this research, environmental simulation can be a decision-making tool, in- tegrating the concept of continuity into the design process.

title	From Bones to Bricks: Design the 3D Printed Durotaxis Chair and La Burbuja Lamp
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. 318-325
doi	https://doi.org/10.52842/conf.acadia.2016.318
summary	Drawing inspiration from the variable density structures of bones and the self-supported cantilvers of corbelled brick arches, the Durotaxis Chair and the La Burbuja lamp explore a material-based design process by responding to the challenge of designing a 3D print, rather than 3D printing a design. As such, the fabrication method and materiality of 3D printing define the generative design constraints that inform the geometry of each. Both projects are seen as experiments in the design of 3D printed three-dimensional space packing structures that have been designed specifically for the machines by which they are manufactured. The geometry of each project has been carefully calibrated to capitalize on a selection of specific design opportunities enabled by the capabilities and constraints of additive manufacturing. The Durotaxis Chair is a half-scale prototype of a fully 3D printed multi-material rocking chair that is defined by a densely packed, variable density three-dimensional wire mesh that gradates in size, scale, density, color, and rigidity. Inspired by the variable density structure of bones, the design utilizes principal stress analysis, asymptotic stability, and ergonomics to drive the logics of the various gradient conditions. The La Burbuja Lamp is a full scale prototype for a zero-waste fully 3D printed pendant lamp. The geometric articulation of the project is defined by a cellular 3D space packing structure that is constrained to the angles of repose and back-spans required to produce un-supported 3D printing.
