title	Developing Concrete Polymer Building Components for 3D Printing
source	ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 152-157

summary	The creation of building components that can be seen as sustainable, inexpensive, stronger, recyclable, customizable and perhaps even reparable to the environment is an urgent, and critical focus of architectural research. In the U.S. alone, the construction industry produced 143.5 million tons of building-related construction and demolition debris in 2008, and buildings, in their consumption of energy produce more greenhouse gasses than automobiles or industry.Because the inherent nature of 3D printing opens new possibilities for shaping materials, the process will reshape the way we think about architectural building components. Digital materiality, a term coined by Italian and Swiss architects Fabio Gramazio and Matthias Kohler, describes materiality increasingly enriched with digital characteristics where data, material, programming and construction are interwoven (Gramazio and Kohler, 2008). The research aspires towards this classification through the use of parametric modeling tools, analytic software and quantitative and qualitative analysis. Rapid prototyping, which is the automatic construction of physical objects using additive manufacturing technology, typically employs materials intended for the immediate analysis of form, scale, and tactility. Rarely do the materials used in this process have any long-term value, nor does the process - except in rare cases with expensive metal prototyping - have the ability to create actual and sustainable working products. This research intends to alter this state of affairs by developing methods for 3D printing using concrete for the production of long-lasting performance-based components.

title	Top-down Approach for Interaction of Knowledge-Based Parametric Objects and Preliminary Massing Studies for Decision Making in Early Design Stages
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 149-164.
summary	Design activities vary from high-degree of freedom in early concept design stages to highly constrained solution spaces in late ones. Such late developments entail large amount of expertise from technical domains. Multiple parallel models handle different aspects of a project, from geometric master models to specific building components. This variety of models must keep consistency with the design intent while they are dealing with specific domains of knowledge such as architectural design, structure, HVAC, MEP, or plumbing systems. Most of the expertise embedded within the above domains can be translated into parametric objects by capturing design and engineering knowledge through parameters, constraints, or conditionals. The aim of this research is capturing such expertise into knowledge-based parametric objects (KPO) for re-usability along the design process. The proposed case study ‚Äì provided by SOM New York‚ is the interaction between a massing study of a high-rise and its building service core, which at the same time handles elevators, restrooms, emergency stairs, and space for technical systems. This project is focused on capturing design expertise, involved in the definition of a building service core, from a high-rise senior designer, and re-using this object for interaction in real-time with a preliminary massing study model of a building, which will drive the adaption process of the service core. This interaction attempts to provide an integrated design environment for feedback from technical domains to early design stages for decision-making, and generate a well-defined first building draft. The challenges addressed to drive the instantiation of the service core according to the shifting characteristics of the high-rise are automatic instantiation and adaptation of objects based on decision rules, and updating in real-time shared parameters and information derived from the high-rise massing study. The interaction between both models facilitates the process from the designer‚Äôs perspective of reusing previous design solutions in new projects. The massing study model is the component that handles information from the perspective of the outer shape design intent. Variations at this massing study model level drive the behavior of the service core model, which must adapt its configuration to the shifting geometry of the building during design exploration in early concept design stages. These variations depend on a list of inputs derived from multiple sources such as variable lot sizes, building type, variable square footage of the building, considerations about modularity, number of stories, floor-to-floor height, total building height, or total building square footage. The shifting combination of this set of parameters determines the final aspect of the building and, consequently, the final configuration of the service core. The service core is the second component involved in the automatic generation of a building draft. In the context of BIM, it is an assembly of objects, which contains other objects representing elevators, restrooms, emergency stairs, and space for several technical systems. This assembly is driven by different layouts depending on the building type, a drop-off sequence, which is the process of continuous reduction of elevators along the building, and how this reduction affects the re-arrangement of the service core layout. Results from this research involves a methodology for capturing design knowledge, a methodology for defining the architecture of smart parametric objects, and a method for real-time-feedback for decision making in early design stages. The project also wants to demonstrate the feasibility of continuous growth on top of existing parametric objects allowing the creation of libraries of smart re-usable objects for automation in design.

title	InfoMatters, a multi-agent systems approach for generating performative architectural formations
source	International Journal of Architectural Computing vol. 9 - no. 3, 205-222
summary	The research paper exemplifies upon a computationally intensive inter-disciplinary research driven design investigation into spatializing the relationship between digital information and physical matter. Focusing on the development of architectural scale urban inserts, the design-research work operates on the intersection of information technology, environmental design, architecture, and computer aided manufacturing domains.The research framework revolves around developing a seamless integration of the aforementioned disciplines in order to establish iterative simulation driven methodologies for generating bottom-up sustainable architectural formations. This is achieved by establishing parametrically driven relational linkages between differential data sets (environmental, social, topological, material etc), which formulate the context (both global and local) within which the proposed project has to be designed. A selforganizing multi-agent system based simulation methodology for generating resultant spatial formations, in time, based on the impacts of the parametric relationships between the aforementioned data sets is eventually embarked upon. This implies, understanding the site as a dynamic information field within which interdependent ecology of agents (representing typology of people, program, structure, speed, desired social interaction etc) with multi-level relational affinities amongst each other as well as the dynamic urban information field. The resultant self-organized multi-agent formations are iteratively mined for identifying logical three-dimensional structural patterns or subjected to programmatic and environmental need driven additional layer of structural simulation with pre-embedded material restraints. An optimized system of multi-performative components that not only populates but also serves as an integrated structural + skin system of the results obtained from the agent based simulations (based upon the degree of inclusion/exclusion of parameters such as the amount of light, sound, wind etc) is subsequently generated. These experimental projects attained the status of self-evolving ecologies of multi-dimensional agents with embodied behavioural profiles, thus providing engaged, highly interdependent design by simulation outputs. The outputs showcase a dynamic system's driven approach towards sustainable design by stressing upon the idea of cohesively binding information and material systems from the very beginning of the design process. Such approaches help in reducing post-optimization of built form and consequently allow for rational understanding of performance criteria and its impact on formal articulations throughout the design process.

title	Navigating Complex Models in Collaborative Work for (Sustainably) Integrated Design
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 619-636.
summary	Increasingly intensive use of computational techniques such as parametric-associative modeling, algorithmic design, performance simulations and generative design in architecture, engineering and construction are leading to increasingly large and complex 3D building models which in turn require increasingly powerful techniques in order to be manipulated and interpreted effectively. Further complexities are of course due also to the multi-disciplinary nature of building projects, in which there can be significant variation and even conflict among the aims of architects, engineers and builders, as well as owners, occupants and other stakeholders in the process. Effective use of model information depends to a large extent on sense-making, which can in some ways be helped but also hindered by schemes for organizing the information contained. Common techniques such as layering, labeling (aka ‚Äòtagging‚Äô) and assignment of various other attributes to model objects have significant limitations ‚Äì especially those arising from general problems of language, ontology and standardization, as well as but distinct from issues of interoperability ‚Äì both with respect to locating the desired items in a 3D building model and also with respect to displaying the objects in informative ways which effectively assist collaborative design and decision-making. Sustainable design in particular is an area generally requiring a high level of inter-disciplinary collaboration to achieve highly integrated designs which make multiple use of the elements and systems incorporated (though integrated design may also be pursued without explicit aims of sustainability). The proposed paper describes ongoing research concerning alternatives to the currently common techniques for locating and displaying information in 3D building models in support of sense-making to promote collaborative and integrated design. These alternatives comprise on the one hand interactive geometric-content-based methods for search and classification of model objects ‚Äì as an alternative or complement to common assigned-attribute-based methods ‚Äì and on the other hand visual analytic techniques ‚Äì in contrast to existing, relatively static tabular and "physical" views ‚Äì which can help to increase the informativeness of the geometric data within the model, as well as the non-geometric data that is attached to geometric objects (e.g. as in the cases of BIM and various types of CAE performance simulations). Tests undertaken with architects and engineers in practice and academia to evaluate the proposed methods are also described. Finally conclusions are drawn regarding these methods‚Äô positive present performance and some of their shortcomings, as well as indicating directions for future research concerning the methods‚Äô refinement and extension to help 3D building models become more effective components of the design process than they are at present, both with respect to these models‚Äô present levels of complexity and especially with respect to their anticipated increasing complexity in future.

title	Just Passing Through: Integration in Computational Environmental Design
source	ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 292-299
doi	https://doi.org/10.52842/conf.acadia.2011.292
summary	This paper proposes Buckminster Fuller’s concept of pattern integrity as a context for understanding computational techniques in environmentally responsive design. We argue that successful integration in this context requires a continuous design medium that allows for heterogeneous, mutable techniques and models. This model of integration is demonstrated by reference to a current project for a large canopy structure in Singapore with specific focus on issues of environmental mediation, object-oriented programming for CAD environments, and functional programming techniques within parametric modeling systems. We discuss the applicability of these novel integrative approaches to wider problems in computational design.

title	Building Skin Intelligence: A parametric and algorithmic tool for daylighting performance design integration
source	ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 170-177
doi	https://doi.org/10.52842/conf.acadia.2011.170
summary	The research presents a methodology and tool development which delineates a performance-based design integration to address the design, simulation, and proving of an intelligent building skin design and its impact on daylighting performance. Through the design of an algorithm and parametric process for integrating daylighting performance into the design phase an automated configuration evaluation is achieved. Specifically the tool enables design exploration of semi autonomous and fully autonomous configurations of an exterior building envelope louver system. The research situates itself in the field of intelligent building skins and adds to the existing solutions a validation of systems with interdependent louvers of varying tilt angles. The system is designed to respond to dynamic daylighting conditions and occupants’ preferences. Within the framework of this study, Grasshopper, Rhino, Galapagos and DIVA, are linked and coded into one integrated process, facilitating design optioneering with near real time feedback. The paper concludes with a description of the tool set’s extensibility, future incorporation of domain integration, and conflation of natural and physical system interaction and complexity.

summary	This paper presents a research on the use of shape grammars as an analytical tool in the history of architecture. It evolves within a broader project called Digital Alberti, whose goal is to determine the influence of De re aedificatoria treatise on Portuguese Renaissance architecture, making use of a computational framework (Krüger et al., 2011).Previous work was concerned with the development of a shape grammar for generating sacred buildings according to the rules textually described in the treatise. This work describes the transformation of the treatise grammar into another grammar that can also account for the generation of Alberti’s built work.

title	Algorithmic Modeling: Teaching Architecture in Digital Age
source	Parametricism (SPC) ACADIA Regional 2011 Conference Proceedings
doi	https://doi.org/10.52842/conf.acadia.2011.x.a0p
summary	Can a working knowledge of algorithmic modeling augment student understanding of building architecture? This question is fundamental when addressing student design education today. This paper demonstrates that when students apply a reductive process more in line with Newell, Shaw and Simon (Newell, Shaw and Simon 1957), they can break down a complex problem into simpler and simpler terms until the problem can be resolved. This type of reduction can be applied systematically to the parametric-driven form through reverse engineering. In the process of reverse engineering, students begin to connect descriptive geometry with complex form, breaking down the complex form into its simplest parts. This design process of reduction and reverse engineering leads designers to take a more systematic approach to theoretical ideas, at once creating complex constructs while pragmatically attacking the issues of buildable form. This paper will delve into teaching analytical tools so students not only comprehend the input of form-making, but the necessary output to test building and material concepts. Fostering a clear methodology for testing built form within the design process also furthers the student’s development as a problem solver and design innovator.

summary	Performative Architectural Morphology is a notion derived from the term Functional Morphology in biology and describes the capacity of an architectural material system to adapt morphologically to specific internal constraints and external influences and forces. The paper presents a research project that investigates the possibilities and limitations of informing a robotically manufactured finger-joint system with principles derived from biological plate structures, such as sea urchins and sand dollars. Initially, the material system and robotic manufacturing advances are being introduced. Consequently, a performative catalogue is presented, that analyses both the biological system’s basic principles, the respective translation into a more informed manufacturing logic and the consequent architectural implications. The paper concludes to show how this biologically informed material system serves to more specifically respond to a given building environment.

title	Heavy Design
source	International Journal of Architectural Computing vol. 9 - no. 3, 251-258
summary	Digital tools in architecture have a powerful capability that we have only begun to explore; the questions to ask of them are perhaps not what they can do but what should we use them for? To date, much of the work done in the area of computational design has been used as elaborate patterning - some have called it ‘ornament’. The significance of this ornament is not only pleasure but in its use of digital patterns to represent our current complex and digital age.This representation in itself is not problematic; however, what is problematic is the lack of other meaningful uses of the digital form-generating tools and their distance from a culture of making. The main failing of our use of digital design (algorithmic or not) in architecture to this point is its inability to translate smoothly from the digital world to the physical world. The main reasons for this difficulty in translation are gravity and inherent material properties. Working with gravity and its physical implications is generally considered the role of the structural engineer; as such, engineers have generally created digital tools in this area.The engineer's methodology analyses a structure based on complex structural analysis programming but in order to do this, a detailed description of the structure must already exist. This is not useful in preliminary stages of design. However, the generation of architecture within an environment, which already includes structural principles, may bring us one step closer to this transition of virtual to physical by including gravity in architectural generation while not diminishing the creative form-generating process. An approach has been proposed which responds with a concept of ‘heavy design’. This type of approach incorporates logics from other disciplines, primarily structural engineering, to inform design. The design process incorporates the structural behavior of a system into the architectural model. Engineering offers a mathematical interpretation of the physical world and this is inherently suited to algorithmic design because it is already in equation form. It can thus be programmed into the architectural form generational software. The variables used in the equations become the variables within the architectural design and this inherently brings the natural physical laws to the architecture through a numerical, algorithmic method. The design produced is not a singular answer but rather a responsive vocabulary of a structural system, which is then employed in design in differing conditions. The architecture produced is both function and ornament, having cultural interpretation but carrying out many engineering tasks: a true parametric architecture.

doi	https://doi.org/10.52842/conf.acadia.2011.284
summary	The research project, tetrahedron cloud, explores agent-based stochastic behavior as a design tool. It investigates the possibilities for producing volumetric tetrahedral meshes based on the interactions of individual stochastic agents. The research situates itself at the intersection of the visual arts, the physical sciences, and computer science. The basic interest in stochastics comes from the visual arts; the growth simulation approach is borrowed from the natural sciences; and the use of a tetrahedral mesh within C++ comes from computer science. But more generally, the project focuses on architecture’s ongoing engagement with stochastic systems. By embedding extremely specific tendencies within an agent’s behavior, while also allowing for stochastic variation, we can create larger systems that are both in and out of our “control”. This sidesteps the typical limitations of many computational geometry and parametric methods, where there is often an overly deterministic relationship between the input and output of a given system. Such a shift from optimization to behavior inevitably brings up troubling questions of style. Abandoning the search for a “best” solution, or even the articulation of the criteria for such a task, re-opens computational architecture at its deepest levels as a site for design speculation.

summary	Acoustic performance is defined by the parameter of reverberation time; however, this does not capture the acoustic experience in some types of open plan spaces. As many working and learning activities now take place in open plan spaces, it is important to be able to understand and design for the acoustic conditions of these spaces. This paper describes an experimental research project that studied the design processes necessary to design for sound. A responsive acoustic surface was designed, fabricated and tested. This acoustic surface was designed to create specific sonic effects. The design was simulated using custom integrated acoustic software and also using Odeon acoustic analysis software. The research demonstrates a method for designing space- and sound-defining surfaces, defines the concept of acoustic subspace, and suggests some new parameters for defining acoustic subspaces.

title	Formation Embedded Design: A methodology for the integration of fabrication constraints into architectural design

doi	https://doi.org/10.52842/conf.acadia.2011.122
summary	This paper presents a methodology for the integration of fabrication constraints within the architectural design process through custom written algorithms for fabrication. The method enables the translation from three-dimensional geometry, or algorithmically produced data, into appropriately formatted machine codes for direct CNC fabrication within a single CAD modeling environment. This process is traditionally one-way with part files translated via dedicated machine programming software (CAM). By integrating the toolpath creation into the design package, with an open framework, the translation from part to machine code can be automated, parametrically driven by the generative algorithms or explicitly modeled by the user. This integrated approach opens the possibility for direct and instantaneous feedback between fabrication constraints and design intent. The potentials of the method are shown by discussing the computational workflow and process integration of a diverse set of fabrication techniques in conjunction with a KUKA 7-Axis Industrial Robot. Two-dimensional knife-cutting, large-scale additive fabrication (foam deposition), robot-mounted hot-wire cutting, and robot-assisted rod-bending are each briefly described. The productive value of this research is that it opens the possibility of a much stronger network of feedback relations between formational design processes and material and fabrication concerns.

summary	The objective of this undergoing research project is to propose a new approach to landscape design education, based on design cognition and computational design theories, such as patterns, shape grammars and parametric design. The system is based on an ontology that contains classes of design concepts and examples of their instances. This paper shows specifically the development of the ontology that will structure the whole system. The information necessary to understand each of the design concepts is represented by a schematic shape grammar rule. Each concept will be illustrated by a good example of application, extracted from the work of Brazilian landscape designer Roberto Burle Marx. A prototypical implementation of the system is being developed, with a hierarchical taxonomy of the concepts and examples.

summary	This paper presents the current development of an in-progress academic research project where a particular design problem, that of building envelopes for tropical climates, is parametrically defined and its possible solutions assessed by means of data correlations and virtual simulations. In doing do so, the authors have devised a parametric structure based on factorial definitions whereby environmental, structural and life cycle analyses are taken into consideration to determine the design possibilities subsequently defined in terms of their physical configuration, constituent materials, construction processes and dynamic behaviour. Particular emphasis is placed on the embedded energy and functional performance of the resulting designs. The proposed methodological model is graphically presented, and its practical potential illustrated by a particular case of application. It should be taken into account, however, that this is a work in progress, and only the first step towards theconstruction of a simulation based methodology for architects and designers.

title	Packing the “Chinese box”: A strategy to manage knowledge using architectural digital models

doi	https://doi.org/10.52842/conf.caadria.2011.717
summary	The architectural design activity has been transformed due to technological advances in building knowledge management. The research proposed is based on a three years long Ph.D. work on 3D models intended as graphical informative systems, layered according to the “Chinese box” paradigm and destined to professionals and researchers in architecture. The applied case study is referred to San Vitale’s church in Ravenna, Italy: the monument was investigated through nested digital models produced by different computer programs. Passing through evolutionary steps identified as synthesis, reduction and projection, the resulting archive lowered its Complication Ratio, a numerical value inspired by fractal’s auto-similarity, indicating a recursive modification in morphologies and contents. Models so conceived are qualified as progressive knowledge-based catalogues easily interchangeable and useful to understand how new or existing architectures work. As a result of this approach, representations obtained with surveys, historical chronicles, light analysis and acoustic simulations were composed following gradual refinements: technical data were collected running parallel to bibliographic research, enriching interactive virtual models sprung from a recursive criterion destined to increase the information enclosed into an undivided, lossless, digital archive.

summary	Many of the most fundamental planning and design decisions in architecture require aesthetic judgments to be made. One decision concerns the balance of a facade composition. Balance is achieved through weighting compositional elements in order to produce stable, holistic patterns. Does this consequently mean that the balance of a facade‘s composition has an important impact on the assessment of a building _s beauty? A study was conducted to test if judgments of beauty and judgments of balance on facades go into the same direction. The question is whether balance is really experienced and incorporated when judging the aesthetic value of a building, especially by non-architects? In order to understand how people experience buildings, and how that experience informs the process of evaluation an eye-movement experiment was conducted, thus elaborating the issue of balance in a facade by measurably relating it to specific architectural design alternatives and their perception and evaluation of the beholder.

title	Analyzing the Ventilation Performance of Tropical High Density Residential Precincts using Computational Fluid Dynamics
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 351-366.
summary	Major cities in the world are getting bigger as they continue to grow to cater for more population increase. These cities normally forced the urban planning to go high density. In the tropical context, high density cities like Singapore and Hong Kong do not have the luxury of space to go low rise and compact. These cities have to build to the floor area ratio of 4 and above to cater for the population. Their only solution is to go up, as high as possible, to the extent that the natural wind flow pattern will be altered, which brings environmental impact to the people. This is generally not good since wind flow helps to maintain the thermal comfort of the people as heat and pollutants are being channeled out of the city to avoid Urban Heat Island effect. In the tropical context, wind flow is crucial to maintain people‚Äôs comfort as the temperature is generally very high from the exposure of the sun for the entire year. Studies have shown that wind flow plays the most significant part in maintaining human comfort despite exposing to direct sunlight in the tropics. Therefore, wind flow analysis is extremely crucial to make the design sustainable and energy efficient, as people will not have to depend on mechanical ventilation to compensate for the lack of wind flow. Computational Fluid Dynamics (CFD) has always been used in the field of architecture, urban design and urban planning to understand the patterns of wind flow through the built environment apart from wind tunnel tests. The availability of more powerful hardware for the mainstream computer users as well as the lowering costs of these computers made CFD more possible to be adopted in the design world today. This also means using CFD in the design process, especially to analyze the impact of the design to the current site conditions and annual wind patterns will help the new design to be more responsive to the site. The interest of this paper is to analyze the high density typologies to see how well they respond to the local wind flow pattern. A typology is considered acceptable when the wind flow going through the site is still maintaining acceptable wind speed. This means it does not block off the wind and create stagnant spaces. Different designs generate different typologies which will respond differently to the wind pattern. The study aims at comparing the local high density typologies in terms of their response to the wind. Changes to a typology can be explored too to see if the performance will be different. For a typology which is considered a total failure in terms of response to wind, it may improve its performance if the orientation is altered. The CFD software can also parametrically respond to the changes of the typologies‚Äô dimensions. This is helpful to see how much more a typology can still be performing well before failure by increasing the floor area index. The easiest way to do this is to pump up the building height. In conclusion, designing in response to wind is extremely important as it is more sustainable and responsive to Urban Heat Island effect. A design which responds well to the wind patterns will help save cost of cooling load and fan expenditure. The people will also be more willing to use the outdoor spaces which will as a whole generate more vibrant city spaces. As a result, a high density city with huge population count can still enjoy good thermal comfort if the general urban planning and design respond well to wind.

summary	For most architects and engineers, the idea of optimizing a building’s design in relation to its location is so ingrained as to be a reflex. Still, most building professionals have a difficult time making the conceptual and practical leap to the notion of performance-based or “adaptive” buildings. We call these adaptive buildings because they can adapt their shape and function in realtime to environmental changes. This field remains far less developed than other areas of practice, but the logic of adaptive performance — which is time-based, responsive, and dynamic — is compelling. Buildings that continuously attune their configurations in accordance with changing environmental conditions use less energy, offer more occupant comfort, and feature better overall space efficiency than static buildings.

title	Form follows parameters: Parametric modeling for fabrication and manufacturing processes

summary	As the architectural field continues to explore the possibilities of parametric design it is important to understand that architectural computation has evolved from representations to simulation and evaluation. This paper explores the digital processes of parametric scripting as a way to generate architectural artefacts that can be realized in the physical landscape through various digital fabrication and industrial manufacturing techniques. This paper will highlight the important discoveries of the geometries and the implications the script has on the construction processes. One benefit of using parametric modelling as a component to the manufacturing pipeline is being able to explore several design iterations in the digital realm before ever realizing them in the physical landscape. Furthermore, parametric modelling allows users to control the production documentation and precision needed to manufacture. As a result, the design pipeline presented in this paper seeks to eliminate the construction processes that hinder the physical act of making architecture.
