title	Stress Line Generation for Structurally Performative Architectural Design
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. 95-109

summary	Principal stress lines, which are pairs of orthogonal curves that indicate trajectories of internal forces and therefore idealized paths of material continuity, naturally encode the optimal topology for any structure for a given set of boundary conditions. Although stress line analysis has the potential to offer a direct, and geometrically-provocative approach to optimization that can synthesize both design and structural objectives, its application in design has generally been limited due to the lack of standardization and parameterization of the process for generating and interpreting stress lines. Addressing these barriers that limit the application of the stress line methods, this paper proposes a new implementation framework that will enable designers to take advantage of stress line analysis to inform conceptual structural design. Central to the premise of the research proposal is a new conception of structurally-inspired design exploration that does not impose a singular solution, but instead allows for the exploration of a diverse high-performance design space in order to balance the combination of structural and architectural design objectives.

title	Point Clouds to BIM: Methods for Building Parts Fitting in Laser Scan Data
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. 358-369.
summary	New construction within existing buildings requires documentation of the existing buildings, in a form that one is familiar with from new construction or architectural design. Laser scanning is a powerful tool to survey the built reality. It provides a replica of the existing building in the form of a point cloud. The difficulty is to analyse the resulting amounts of data that has been generated and being able to interpret it as a Building Information Model (BIM). This article proposes a new generic approach for pattern recognition of architectural objects. The procedure is introduced through the use of two examples - polygon fitting, which is important for the generation of new building element classes and wall detection. The second part describes how individual components can be automatically connected to consistent networks. BIM systems walls should be aligned, within predefined limits of accuracy, either perpendicular to or in line with each other.

title	Structural design based on performance applied to development of a lattice wind tower
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. 326.
summary	This paper studies the process of parametric and algorithmic design, integrating structural analysis and design for the generation of complex geometric structures. This methodology is based on the Performative Model, where the shape is generated using performance criteria. In the approach, the development of complex structures is only possible by reversing the process of thinking to generate the form with established parameters for geometry, material and loading aspects. Thus, the structural engineer no longer only participates in the evaluation phase but also appears in the early stages, creating a process of exploration and production of common knowledge among architects and engineers. To research performance-based design, the development of a conceptual lattice for a wind tower is proposed. Thus, a system is made to generate geometries using Rhinoceros software, the Grasshopper plugin, and the VB programming language, integrated with stress analysis through the Scan & Solve plugin.

title	Spatial Nets: the Computational and Material Study of Reticular Geometries
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. 123-135
doi	https://doi.org/10.52842/conf.acadia.2015.123
summary	Reticular systems are in many aspects a distinct taxonomy of volumetric geometries. In comparison with the conventional embodiment of a ‘volume’ that encapsulates a certain quantity of space with a shell reticular geometries emerge from the accumulation of micro elements to define a gradient of space. Observed in biological systems, such structures result from their material properties and formation processes as well as often ‘simple’ axioms that produce complex results. In micro or macro levels, from forest tree canopies to plant cell walls these porous volumes are not shaped to have a singular ‘solution’ for a purpose; they provide the fundamental geometric characteristics of a ‘line cloud’ that is simultaneously flexible in response to its environment, porous to other systems (light, air, liquids) and less susceptible to critical damage. The porosity of such systems and their volumetric depth also result in kinetic spatial qualities in a 4D architectural space. Built upon a ‘weaving’ organization and the high performance material properties of carbon fiber composite, this research focuses on a formal grammar that initiates the complex system of a reticular volume. A finite ‘lexical’ axiom is consisted of the basic characters of H, M and L responding to the anchor points on the highest, medium and lower levels of the extruding loom. The genome thus produces a string of data that in the second phase of programming are assigned to 624 points on the loom. The code aims to distribute the nodes across the flat line cloud and organize the sequence for the purpose of overlapping the tensioned strings. The virtually infinite results are then assessed through an evolutionary solver for confining an array of favorable results that can be then selected from by the designer. This research focuses on an approximate control over the fundamental geometric characteristics of a reticular system such as node density and directionality. The proposal frames the favorable result of the weave to be three-dimensional and volumetric – avoiding distinctly linear or surface formations.

summary	The research presented in this paper revolves around the experimental development of the morpho-structural potential of folded architectural structures made of wood. The aims are to develop an innovative system for timber used in sustainable construction and to increase the inventory of wood architectural tectonics. Laminated timber panels associated with "digital production line" approach have opened up new perspectives for the building industry in creating prefabricated wooden structures. This article provides a characterization of the digital chain associated to the development of non-standard folded structures which consist of wood panels by way of a full-scale experimental pavilion. The purpose is the study of architectural design process from parametric modeling (through CNC machining) and assembly operations to production. Towards the completion of the pavilion, a number of analytical experiments have been performed.

summary	This paper presents research on the prototyping of multi-agent systems for architectural design. It proposes a design exploration methodology at the intersection of architecture, engineering, and computer science. The motivation of the work includes exploring bottom up generative methods coupled with optimizing performance criteria including for geometric complexity and objective functions for environmental, structural and fabrication parameters. The paper presents the development of a research framework and initial experiments to provide design solutions, which simultaneously satisfy complexly coupled and often contradicting objectives. The prototypical experiments and initial algorithms are described through a set of different design cases and agents within this framework; for the generation of façade panels for light control; for emergent design of shell structures; for actual construction of reciprocal frames; and for robotic fabrication. Initial results include multi-agent derived efficiencies for environmental and fabrication criteria and discussion of future steps for inclusion of human and structural factors.

doi	https://doi.org/10.52842/conf.acadia.2015.137
summary	This paper presents a bottom-up approach to organising architectural-space, which offers a fresh outlook on the automatic generation of architectural layouts. Artificial creatures, modelled on Eukaryotic cells, are used as components with which to generate configurations articulating patterns of habitation. These components represent discrete activities. Activity is perceived to be the basic building block of spatial configuration in architecture. Attributes, pertaining to input and outputs, establish activities as occurring in chains of action; affected by that which has preceded and affecting that which is to transpire. Being artificial creatures these activity-components have the capacity to interact with their environment and each other, and self-organise to form aggregations. The model demonstrates an ecological approach to designing in a manner that unites computational design with biological and semiotic theory. The theoretical basis of the model is first outlined, and then the computer model is presented and described.

summary	Recent developments in responsive electroactive materials are increasing the rate at which next-generation façade technologies can respond to environmental conditions, building energy demands, and the actions of building occupants. Simulating the real-time performance of dynamic façade systems is critical for understanding the impacts that occupant response will have on whole-building energy performance and architectural design. This paper describes a method for real-time analysis of the multi-zone building performance impacts of occupant interaction with a dynamic façade system, the Electroactive Dynamic Display System (EDDS). The objective is to optimize EDDS implementation and define system limitations, incorporate EDDS as a dynamic factor in multi-zone building energy analyses, and provide real-time feedback of building performance data based on environmental conditions and occupant interactions. Preliminary results of parametric simulation methods demonstrate the ability of dynamic façade systems to consider real-time occupant interaction in the analysis of daylighting and thermal performance of buildings.

summary	This paper presents a computationally based methodology arising from the application of weaving techniques for the design and construction of an experimental architectural system, Weaving Enclosure. The research explores the close correspondence between material properties and assembly systems found in the traditional craft of weaving, studied through analytical and laboratory tests, and then implemented through computational design and digital fabrication. The workflow for the generation of specific geometries related to the elastic nature of the material results in the design and fabrication of a self- standing interior partition with digitally conceived patterns, tuned parametrically to provide structural and screening performance.

title	Adaptive Pneumatic Shell Structures - Feedback-driven robotic stiffening of inflated extensible membranes and further rigidification for architectural applications

wos	WOS:000402063700060
summary	The paper presents the development of a design framework that aims to reduce the complexity of designing and fabricating free-form inflatables structures, which often results in the generation of very complex geometries. In previous research the form-finding potential of actuated and constrained inflatable membranes has already been investigated however without a focus on fabrication (Otto 1979). Consequently, in established design-to-fabrication approaches, complex geometry is typically post-rationalized into smaller parts and are finally fabricated through methods, which need to take into account cutting pattern strategies and material constraints. The design framework developed and presented in this paper aims to transform a complex design process (that always requires further post-rationalization) into a more integrated one that simultaneously unfolds in a physical and digital environment - hence the term cyber-physical (Menges 2015). At a full scale, a flexible material (extensible membrane, e.g. latex) is actuated through inflation and modulated through additive stiffening processes, before being completely rigidified with glass fibers and working as a thin-shell under compression.

title	Algorithmic design tool for integrating renewable energy infrastructures in buildings

summary	We present a tool which empowers 'green' design freedom for architects by presenting ever expanding choices in components and materials and automatizing their configuration and placement. Several time- and resource- consuming initial design iterations are eliminated by optimizing the energetic efficiency of the building in the original draft phase. The smart, efficient, energy producing building of the future can thereby offer increased cost and energy efficiency, security and comfort, without any compromise in style and form - on the contrary, the proposed tool stands to open up a novel palette of creative 'green' architectural design elements, which would effectively be co-designed by architects. The proposed algorithmic CAD design tool allows direct integration of renewable sources in the architectural design phase, taking into account local meteorological and solar radiation conditions. Furthermore locally optimized evolution and modification of renewable components integrated into the building's structure is possible, leveraging an increasingly wide range of possibilities in form, finish and renewable energy generation.

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	The paper presents a research on real-time shape exploration employing analogue and digital form-finding and concludes with a proposal for a teaching methodology that led to an intensive student workshop which took place at Graz University of Technology during 2014. The aim was to experiment with analogue and digital tools in parallel, counter-informing the design process. The experiments involved physical form-finding following the tradition of Frei Otto at the Institute of Lightweight Structures in Stuttgart as well as computational form-finding employing mainly dynamic relaxation techniques of spring-particle systems. The combination of techniques and methodologies eventually led to a feedback loop across different media that explored both qualitative and quantitative characteristics of the projects at hand. By establishing feedback between digital media and physical prototypes, the creative process is immediately informed by the material characteristics and properties which in turn give rise to a real-time exploration of form.Simulations of physical forces for architectural form generation are increasingly gaining ground in architectural education as there is a broad selection of computational tools readily available that allow quick experiments to be conducted.

summary	Thermal Form, is architecture that does work. Or, it is the application of energy as information to architectural geometry, with the express purpose of using the resistance of structure against an opposing thermodynamic force, in order to manipulate and direct flows that exist in both the interior and along the exterior of a building. By examining the relationship between surface configuration, surface area and type of energy transfer occurring - with a focus on the mechanism of transfer - thermal form strategies can be used to further optimize existing building typologies and environmental control system strategies, or, perform a more radical detouring of the atmosphere of a building.

summary	Development in the study of city expansion, through biomorphic generation, could potentially assist in the design of a transportation system that will accommodate expansion whilst contributing to an ecologically balanced growth. This paper focuses on a section of a design framework which looks at how generative systems can be implemented in an architectural design of a transportation network that will respond to the site’s projected future growth. This paper suggests that by integrating biomorphic generative systems into the design process we can generate designs that respond to the surrounding context and urban growth.

doi	https://doi.org/10.52842/conf.acadia.2015.431
summary	The idea of an emergent or generative form based on repeating rules of development borrowed from the field of developmental biology has provided fertile ground for inspiration for architectural theory and computational design. With simple constraints developed iteratively, complex geometry and form generation can be distilled down to a list of developmental rules or functions in order to deterministically generate form. The ideas and illustrations of naturalists on organic form and developmental biology leading back to the turn of the 20th c., such as the work of D'arcy Wentworth Thompson and Ernst Haeckel, have inspired architects from Louis Sullivan all the way to contemporary generative design. This study revisits this design tradition of biomimetic geometries based on deterministic rules for the iterative development of forms based on biological analogs and models for growth. A series of semi-regular compound patterns were developed using parametric modeling and iterative rules. These geometries were then applied to surface topologies as a decorative tactile embellishment resulting in complex thermodynamic conditions. A series of physical prototypes where then developed with different high-relief patterns and pattern densities. Positive prototype geometries were then produced using stereolithography for casting plaster molds for the production molding of finished ceramic pieces for thermal analysis using digital thermography. By studying the performance of these complex geometries as physical prototypes under controlled experimentation, high-relief surfaces and the resulting thermodynamic conditions can be understood not just qualitative experience, but also quantitatively through measured performance metrics and innovative tools for analytical analysis.

summary	We have developed a modular approach to the parametric design of a patterned façade for tropical climates, using a “lighter” data set and model that integrates a number of performance considerations. This modular approach separates the façade's design into form, façade pattern, façade density requirements, and façade components, and reintegrates these aspects via a triangular mesh, represented as a fast and convenient data structure based on half-edges. Through this separation, the design team can simultaneously work on the architectural appearance of the design, its performance, and its fabrication, while retaining holistic control through the constant reintegration of design changes via the half-edge data structure. In this way, we retain the advantages of a parametrically driven design process, such as automatic design generation and the integration of performance aspects, while permitting more flexible and non-sequential design explorations by different members of the design team.

summary	Traditionally, architects express their thoughts on the design of 3D architectural forms via perspective renderings and standardized 2D drawings. However, as architectural design is always multidimensional and intricate, it is difficult to make others understand the design intention, concrete form, and even spatial layout through simple language descriptions. Benefiting from the fast development of machine learning, especially natural language processing and convolutional neural networks, this paper proposes a Linguistics-based Architectural Form Generative Model (LAFGM) that could be trained to make 3D architectural form predictions based simply on language input. Several related works exist that focus on learning text-to-image generation, while others have taken a further step by generating simple shapes from the descriptions. However, the text parsing and output of these works still remain either at the 2D stage or confined to a single geometry. On the basis of these works, this paper used both Stanford Scene Graph Parser (Sebastian et al. 2015) and graph convolutional networks (Kipf and Welling 2016) to compile the analytic semantic structure for the input texts, then generated the 3D architectural form expressed by the language descriptions, which is also aided by several optimization algorithms. To a certain extent, the training results approached the 3D form intended in the textual description, not only indicating the tremendous potential of LAFGM from linguistic input to 3D architectural form, but also innovating design expression and communication regarding 3D spatial information.
