summary	The paper discusses an interdisciplinary exchange between parametric design and acoustic simulation. It reviews a strategic development of temporary dynamic structures that can be manipulated by intersecting variations of formation in generative architecture with acoustic simulation. The research investigates drivers that interface knowledge between parametric design, structural engineering and fabrication, interaction design and acoustics, and theatre and performance. It reviews the simulation of a temporary theatre installation into an existent industrial hall, whereby different formation of a modular structure are explored, and the acoustic effects of this installation are evaluated in relation to an enhancement of the audiences spatial and acoustic experience. The research goes beyond the morphological, aesthetic or structural values that have become key aspects of contemporary digital architecture, and relates them to the field of auralisation (forecasting acoustic behaviour). In that manner, the simulation and analysis of a future (material, spatial) objects is developed through the communication of an interdisciplinary team, thus exploring synergetic qualities of the physical and the digital.

title	Design Ecologies for Responsive Environments: Resonant Chamber, an Acoustically Performative System"

summary	This paper positions the development and performance of a responsive acoustic envelope system, called Resonant Chamber, within significant discourses in ecology, systems theory and cybernetics. The project is developed through two dominant threads. First, the synthetic design process that entails engaging simultaneous computational and physical investigations which inform each other through various feedback and control regimes - from simulation and testing frameworks to material limits and behaviors to geometric, technological and manufacturing limitations or constraints. Second, the paper elaborates on the system's embedded sensing, communication, feedback and actuation system that transforms its performance to a kinetic, responsive environment that opens up possibilities for active acoustic control, as well as open-ended interaction and play with inhabitants. Within this paradigm, the designer operates through an adaptive mode, between control and the dynamic shaping of possibilities within digital, physical and effective logics, constraints and opportunities.

title	Functionally Graded Aggregate Structures: Digital Additive Manufacturing With Designed Granulates
doi	https://doi.org/10.52842/conf.acadia.2012.295
source	ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 295-304
summary	In recent years, loose granulates have come to be investigated as architectural systems in their own right. They are defined as large numbers of elements in loose contact, which continuously reconfigure into variant stable states. In nature they are observed in systems like sand or snow. In architecture, however, they were previously known only from rare vernacular examples and geoengineering projects, and are only now being researched for their innate material potentials. Their relevance for architecture lies in being entirely reconfigurable and in allowing for structures that are functionally graded on a macro level. Hence they are a very relevant yet unexplored field within architectural design. The research presented here is focused on the potential of working with designed granulates, which are aggregates where the individual particles are designed to accomplish a specific architectural effect. Combining these with the use of a computer-controlled emitter-head, the process of pouring these aggregate structures can function as an alternative form of 3D printing or digital additive manufacturing, which allows both for instant solidification, consequent reconfiguration, and graded material properties. In its first part, the paper introduces the field of research into aggregate architectures. In its second part, the focus is laid on designed aggregates, and an analytical design tool for the individual grains is discussed. The third part presents research conducted into the process of additive manufacturing with designed granulates. To conclude, further areas of investigation are outlined especially with regard to the development of the additive manufacturing of functionally graded architectural structures. The potentials of the methodologies developed in this process are shown through the fabrication of a full-scale installation. By integrating material, fabrication, and design constraints into a streamlined computational methodology, the process also serves as a model for a more intuitive production workflow, expanding the understanding of glass as a material with wide-ranging possibilities for a more performative architecture.

summary	The paper presents the current development of an ongoing research project about the integration of robotic fabrication strategies in computational design through morphological and functional principles derived from natural systems. Initially, a developed plate structure material system based on robotically fabricated fi nger joints is being informed by biomimetic principles from the sea urchin Clypeasteroida in order to be able to adapt effi ciently to its building environment. Consequently, the paper’s main focus lies on translating the biomimetic design principles into a computational design tool, also integrating fabrication parameters as well as structural and architectural demands. The design tool’s capability to integrate these parameters is shown by the design, development and realization of a full-scale research pavilion. The paper concludes with discussing the performative capacity of the developed material system and the introduced methodology.

summary	The paper presents research into computational design processes that integrate not only criteria of physical producibility but also characteristics of design intelligence and performance. In the first part, the use of an industrial robot’s design space for developing differentiated finger joint connections for planar sheets of plywood is being introduced. Subsequently, biomimetics is proposed as a filter for the possible geometric differentiations with respect performative capacities. The second part focuses on the integration of fabricational and biomimetic principles with structural and architectural demands, as well as by the development of a custom digital data structure for the fabrication of finger joint plate structures resulting in the construction of a full scale prototype. The paper concludes with evaluating the tolerances inherent in construction through 3D laser scan validation of the physical model.

title	The Synergy Between Structure and Ornament: A Reflection on the Practice of Tectonic in the Digital and Physical Worlds
doi	https://doi.org/10.52842/conf.ecaade.2012.2.245
source	Achten, Henri; Pavlicek, Jiri; Hulin, Jaroslav; Matejovska, Dana (eds.), Digital Physicality - Proceedings of the 30th eCAADe Conference - Volume 2 / ISBN 978-9-4912070-3-7, Czech Technical University in Prague, Faculty of Architecture (Czech Republic) 12-14 September 2012, pp. 245-254
summary	The use of digital design and fabrication technologies in architecture has followed a paradigm shift, which has seen the topology, form and structure of architecture pushed to incorporate areas such as climate, construction, acoustic etc. While these digital technologies are intended to enhance the processes and performance, a discussion of aesthetics has been ignored. Surmising that the use of digital technology enhances the performability and effi ciency aspects of architecture as well as the aesthetics, this research questions what the new relationships and arrangements for structure and ornament are. What are the challenges when structure uses a process-based logic and is sensitive to materiality whereas the aesthetics has a representation-based logic and is not sensitive to materiality? The authors of this paper contribute to this debate by using the notion of tectonic as a platform for gaining and creating knowledge about this issue and examining the issues through the design and prototyping of a Multi-functional Pavilion.

summary	This paper explores the sonic characteristics of urban spaces, with the application of apprehending acoustic space and form theory. The theory defines auditory spaces as acoustical arenas, which are spaces defi ned and delineated by sonic events. Historically, cities were built around a soundmark, for example, the resonance of a church bell or propagation of a calling for prayer, or a factory horn. Anyone living beyond the horizon of this soundmark was not considered citizens of that town. Furthermore, the volume of urban sonic arenas depends on natural. Digital simulation is necessary to visualize the ephemeral and temporal nature of sound, within a dynamic immersive environment like urban spaces. This paper digitally analyses the different morphologies of old cities and forms of growth in relation to the sound propagation and ecological effects. An experiment is conducted with the aid of an ancient North-African city model, exposed to a point cloud agent system. By analysing how the sound propagates from the known soundmark through the urban fabric, with the wind pressure interference; the paper compares the theoretical concept of soundmarks and the known perimeter of the ancient city

summary	The research investigates the application of evolutionary computation in relation to sound based morphogenesis. It does so by using the Sabine equation for performance benchmark in the development of the spatial volume and refl ectors, effectively creating the architectural expression as a whole. Additional algorithms are created and used to organise the entire set of 200 refl ector components and manufacturing constraints based upon the GA studies. An architectural pavilion is created based upon the studies illustrating the applicability of both developed methods and techniques.

summary	This paper presents a case study of the pavilion built with the participation of students during experimental design course of ASK studies, master program in Warsaw. The installation was developed to research programming behaviour of augmented space. Pavilion generates acoustic signals in relation to user actions. It does so, according to the rules stored in a program that can be changed through the user interface. The pavilion serves both as a didactic and experimental installation. Therefore, a single low-tec sensor was invented, which operation can be easily understood. Optical mechanism analyzes the image of a shadow to obtain information about interior use. Components of the experiment are used to control process and establish rules. Mode of action is defined by independently designed system procedure.

summary	The use of the method "simulation" of the microclimate for an urban site presents much of interest; because this can serve as us observation and analysis of the consequences of various scenarios relating to the existence and the importance of the constituent elements in urban space. Wind in outdoor urban space is among the most difficult parameters to identify and control field given its instability. Currently, in the field of the ventilation, there are some outdoor spaces simulation tools, used to assess the flow of the wind at different spatial scales. The aim of this research is to demonstrate the effect of the urban geometry of the layout on the wind movement and the outdoor natural ventilation. However, this study investigated the effect on outdoor thermal comfort of a building layouts in a planned residential area situated in the city of Jijel humid Mediterranean region of Algeria. In order to improve outside comfort in this open space, a 3D numerical simulation tool ENVI-met 3.1 beta 4 was used to simulate the urban thermal climate taking into account various scenarios. Thus, simulation’s results are discussed in this paper

source	In Petruschat and Adenauer (eds), Neue Formen des Prototypings in Gestaltungsprozessen, Form+Zweck, Berlin, 2012
summary	Architects by profession, Christian Derix and Asmund Gamlesæter are interested in expanding the capabilities of digital technology to inform, support and enrich the design process in architecture and spatial planning. The computational prototypes they develop range from form studies to visualization of complex processes in spatial planning such as movement behaviors of people in a city. They work analytically as well as generatively and the approach is deeply affected by the understanding that computing systems should not define solutions but offer creative freedom and create a symbiosis between the designer and the algorithmic intelligence. They are rather designed to help the designer view the design problem and consequences of decisions from different perspectives. Encouraging the designer to play through different narratives. They are rather tools for thinking through multiple solutions and allow the designer to play with the possibilities. The generation of the final design is inspired and validated by the tools but remains in the hands of the designer.

summary	This paper presents a currently on-going research trajectory, investigating integrated design and build work-fl ows using generative design strategies and custom built fabrication devices. The aim of the research, which is being developed through a series of experiments and workshops, is to explore scenarios in which these work-flows can produce emergent architectural structures which are highly adapted towards the intended performance within their specifi c context and site. The research has produced a number of installations and prototypical structures which test the practical and theoretical dimensions of the methodology explored. This paper will introduce intriguing new scenarios in which the architects’ role is focused on an indirect, advanced level of control of the process of design, allowing for a more open-ended method of negotiation between structure, users and environment.

summary	This paper presents a concept of origami as a form-generator for a structural system that allows deployability for structures with large spans. The presented approach studies the embedded kinetic possibilities of folded structures and focuses on a parametric modelling process that allows evaluating the structural performance of different types of the same origami family in order to optimize the geometry for a given scenario. The workfl ow between scripting based form generation – within Rhinoceros and Excel – and LS-DYNA is presented in detail. In addition to that the question of scalability from a thin microstructure to a thickened roof structure is discussed in the context of an architectural project.

summary	Architecture today has come to its most complex form. There are lots of criteria such as fi re safety, structure, sustainability etc… which must be controlled by the designers. To improve the performance and accessibility of buildings, governing bodies publish different codes for each of the different criteria. Buildings must comply with these codes to get a permit for construction. The checking of the buildings according the codes is done manually by code offi cials. This process is time consuming, high in cost and prone to errors. To remedy this problem by using the tools like BIM and AI, systems that can automatically check the code compliance of projects are being developed. In this paper we provide an overview of the structures and capabilities of these systems and present the automated code compliance checking system that we develop for checking building models against some parts of the Turkish Fire Codes.

title	Zero-Waste, Flat-Packed, Tri-Chord Truss: Continued Investigations of Structural Expression in Parametric Design"
doi	https://doi.org/10.52842/conf.acadia.2012.199
source	ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 199-208
summary	The direct and rapid connections between scripting, modeling and prototyping allow for investigations of computation in fabrication. The manipulation of planar materials with two-dimensional CNC cuts can easily create complex and varied forms, volumes, and surfaces. However, the bulk of research on folding using CNC fabrication tools is focused upon surfaces, self-supporting walls and shell structures, which do not integrate well into more conventional building construction models. This paper attempts to explain the potential for using folding methodologies to develop structural members through a design-build process. Conventional building practice consists of the assembly of off-the-shelf parts. Many times, the plinth, skeleton, and skin are independently designed and fabricated, integrating multiple industries. Using this method of construction as an operative status quo, this investigation focused on a single structural component: the truss. Using folding methodologies and sheet steel to create a truss, this design investigation employed a recyclable and prolific building material to redefine the fabrication of a conventional structural member. The potential for using digital design and two-dimensional CNC fabrication tools in the design of a foldable truss from sheet steel is viable in the creation of a flat-packed, minimal waste structural member that can adapt to a variety of aesthetic and structural conditions. Applying new methods to a component of the conventional ‘kit of parts’ allowed for a novel investigation that recombines zero waste goals, flat-packing potential, structural expression and computational processes. This paper will expand (greatly) upon previous research into bi-chord truss designs, developing a tri-chord truss, which is parametrically linked to its structural moment diagram. The cross section of each truss is formed based on the loading condition for each beam. This truss design has been developed through a thorough series of analytical models and tests performed digitally, to scale and in full scale. The tri-chord truss is capable of resisting rotational failures well beyond the capacity of the bi-chord designs previously developed. The results are complex, and elegant expressions of structural logics embodied in a tightly constrained functional design.

title	Data sharing for sustainable assessments: Using functional databases for interoperating multiple building information structures

summary	This paper presents the development and implementation of an automatic sustainable assessment prototype using functional databases. For the practical purpose, we use Leadership in Energy and Environmental Design (LEED) as the exemplar standard to demonstrate the integrative process from building information aggregation to final evaluation. We start with a Building Information model, and use Construction Operations Building Information Exchange (COBie) as a bridge to integrate LEED requirements. At present, the process of sustainable building assessment requires information exchange from various building professionals. However, there is no procedure to manage, or use, information pertaining to sustainability. In our research, we translate rules from LEED into computable formulas and develop a prototype application to produce templates for LEED submission.

summary	Knowledge of geometric drawing, hitherto considered previous in the training context in architecture, has little emphasis in the school curriculum. In the context this work, were recognized approaches such as shape grammar, which explain design practices, unveiling relationships of the geometric form. It was also identified practices of the Gestalt, established under the modern architecture, which sought to stimulate the student to have insights to think about geometric structures implicit in the form. From these references and digital tools, it is demonstrated the types of concepts and some of the exercises that are being used for the configuration of an learning for the insight.
