source SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 397-400
summary The objective of the present paper is to propose a design solution database to help students learn basic landscape design concepts and help them apply this new knowledge by using examples developed by an experienced designer. The system is based on an ontology that contains classes of design concepts and design instances. Beyond the structure to search for design concepts and precedents, it’s also proposed an interactive module implemented in a parametric design tool. This module allows students generate and insert automatically different parametric components, such as a group of trees, bushes, sculptures, in a digital model. The system efficacy was verified in a workshop performed with undergraduate students.

summary During early-stage planning, numerous design decisions are taken in an argumentative manner, based on occupation with the building site according to the different infl uencing aspects (e.g. topology, wind, visibility, circulation, activities etc.). In this context, sketches, diagrams and spreadsheets are the workhorses for elaboration. However, some of these phenomena are dynamic by nature, and are rather poorly modeled when utilizing static media. In our work, we thus show how agent-based simulation can be used to compute and visualize dynamic factors, in order to inform the decision process on a qualitative level. As a matter of fact, simulations may be used as a design tool in their own right, for analysis and objectifi ed comparison among multiple design variations.

summary The paper presents a design build studio that investigates the role of waste as building material and develops a proposal for an installation that uses CAAD and CAM tools in combination with traditional fabrication tools to design and build an installation out of waste materials. The paper describes the concept development and the construction process through the help of computational tools. Recycling is in the process of becoming an integral part of sustainable architecture. However, there are very few digital design projects that use re-used or recycled materials in combination with their architectural and aesthetic qualities and potentials. The potential of such an investigation is explored within a design build studio. What is junk? What is a building material? What are the aesthetics of junk?

summary This paper discusses an educational design methodology for undergraduate studio instruction, which uses a systematic and research based design approach. Based on Lars Spuybroek’s methodology that was originally developed as a one-year graduate and postgraduate studio, a new method for undergraduate teaching has been developed. The paper will discuss Spuybroek’s methodology, as developed for the graduate and postgraduate program, and explain its adaption for undergraduate studio instruction. Spuybroek’s approach is based on a model that starts with research in systems in general that is them tuned to a certain set of architectural questions and developed into parametric buildings in a stepwise procedure by delaying the specifics of site and program.

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.

source Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 527–536
summary The method proposed in this project addresses the parametric manipulation of a given pattern to respond directly to a pre-defined surface. Continuing the research of Kevin Rotheroe, Yale University and founder of FreeForm Design. Rotheroe has developed a series of studies in material and surface properties. By utilising a proven pattern, the proposed method sets parameters derived from the formal properties of the original pattern and produces a new pattern that is responsive to the curvature of a complex surface. The workflow developed in this research consists of a complex blending of tools in Grasshopper and Gehry Technologies Digital Project. The intent is to achieve the aesthetics and structure offered by Rotheroe’s original research and to add a responsive precision that provides an accurate adaptation of the pattern based on curvature of a specific computationally defined surface.

summary The article presents a graph-based spatial analysis toolset (“decoding spaces”components) which we have recently developed as an extension of the visual scripting language Grasshopper3D for Rhino. These tools directly integrate spatial analysis methods into CAD design software which can have a signifi cant effect on current design workfl ows. However,grasshopper doesn’t only enable the results of analyses to be used in the standard Rhino modelling environment. It also makes it possible to integrate spatial analysis into a parametric design approach as discussed in this paper. The functionality of this toolset is demonstrated using a simple urban design scenario where we introduce the idea of parametric patterns based on graph-measures.

title CAD Scripting and Visual Programming Languages for Implementing Computational Design Concepts: A Comparison from a Pedagogical Point of View
source International Journal of Architectural Computing vol. 10 - no. 1, 121-138
summary This paper compares the use of scripting languages and visual programming languages for teaching computational design concepts to novice and advanced architecture students. Both systems are described and discussed in terms of the representation methods they use. With novice students better results were obtained with the visual programming language. However, the generative strategies used were restricted to parametric variation and the use of randomness. Scripting, on the other hand, was used by advanced students to implement rule-based generative systems. It is possible to conclude that visual languages can be very useful for making architecture students understand general programming concepts, but scripting languages are fundamental for implementing generative design systems. The paper also discusses the importance of the ability to shift between different representation methods, from more concrete to more abstract, as part of the architectural education.

summary This paper is part of an ongoing research that analyzes the housing projects of the Dutch office MVRDV through their theoretical research and design processes. The text focuses on the use of parametric software according to two key aspects that qualify their production: research and conceptual creative potential. Since the late 1990s, the architects are positioning their practice under a strategy that combines collection, processing and interpretation of large amounts of data, what means the conversion of statistical information into concrete and inventive form. With this demand the office developed parametric software as Regionmaker, the case study presented here.

summary This paper presents part of CORK’EWS, a research work developed within the framework of the Digital Architecture Advanced Program 2012/13 at ISCTE-IUL. The main goal of this investigation was to develop a parametric, customizable and adaptive wall system designed for environmental performance. Moreover, the system is based on standard industrial products: expanded cork blocks produced by Amorim Insulation industries. CAD/CAM resources were the essential tools of the research process, where fundamental and practical knowledge is integrated to understand the microstructure morphological properties of the raw material – cork – and its derivate – natural expanded cork. These properties were upscale and adapted to create a wall with an optimized solar control environmental performance. The result is a digitally fabricated prototype of a new customizable industrial product, adaptable to specific environmental conditions and installation setups being therefore easily commercialized. From microstructural morphology to macroscale construction, the research explores new application possibilities through morphogenesis and opens new possible markets for these customizable products.

summary Histories are underdeveloped and underused features in parametric CAD (PCAD) systems. Designers employ backtracking and deferral strategies that both use and augment history. Using backtracking and deferral as a framework we present two classes of design process graph diagramming techniques for augmented history in PCAD. We compare the second version of these design process graphs across several designers who completed multiple tasks using two parametric systems (SolidWorks and GenerativeComponents). The two systems show similar types of action, with markedly more and deeper backtracking in GenerativeComponents. We present a third diagramming system as a design for a proof of concept prototype. This prototype aims to expand the capabilities of design histories beyond access to single prior states to visualize and enable direct interaction based on backtracking and deferral.

summary Cash-Back 1.0 presents research on the development of methodologies and technologies to simulate the cause and effect of early stage geometric design alternatives of buildings and the real time results upon financial pro-forma. Through the encoding of design rules and their associative relationships to financial pro-forma the research illustrates enhanced visualization of early stage building design decisions and their cumulative impact on financial goals and constraints. The research presents value an associative parametric design process affords often-disparate domains through correlation and visualization. The paper describes incorporation of a feedback loop between pro-forma and geometric models in conjunction with an optimization method. Given the level of uncertainty in early stage design decision making the research contributes partial solutions to the domain problems of design decision uncertainty and design cycle latency and is further argumentation for increased use of parametric design methods and automation to support design domain integration.

title Synthesizing Design Performance: An Evolutionary Approach to Multidisciplinary Design Search

summary Design is a goal oriented decision-making activity. Design is ill defined and requiring of synthetic approaches to weighing and understanding tradeoffs amongst soft and hard objectives, and the imprecise and or computationally explicit criteria and goals. In this regard designers in contemporary practice face a crisis of sorts. How do we achieve performance under large degrees of uncertainty and limited design cycle time? How do we better design for integrating performance? Fundamentally design teams, are not typically given enough time nor the best tools to design explore, to generate design alternatives, and then evolve solution quality to search for best fit through expansive design solution spaces. Given the complex criteria for defining performance in architecture our research approach experiments upon an evolutionary and integrative computational strategy to expand the solution space of a design problem as well as pre-sort and qualify candidate designs. We present technology and methodology that supports rapid development of design problem solution spaces in which three design domains objectives have multi-directional impact on each other. The research describes the use of an evolutionary approach in which a genetic algorithm is used as a means to automate the design alternative population as well as to facilitate multidisciplinary design domain optimization. The paper provides a technical description of the prototype design, one that integrates associative parametric modeling with an energy use intensity evaluation and with a financial pro forma. The initial results of the research are presented and analyzed including impacts on design process; the impacts on design uncertainty and design cycle latency; and the affordances for ‘designing-in’ performance and managing project complexity. A summary discussion is developed which describes a future cloud implementation and the future extensions into other domains, scales, tectonic and system detail.

summary The challenge of developing adaptive, responsive low-energy architecture requires new knowledge about the complex and dynamic interaction between envelope architecture and optimisation between competing environmental performance metrics. Advances in modelling the geometry of building envelopes and control technologies for adaptive buildings now permit the sophisticated evaluation of alternative envelope configurations for a set of performance criteria. This paper reports on a study of the parametric control of a building envelope based on moveable façade components, acting as a shading device to reduce thermal gain within the building. This is investigated using a novel pentagonal tiling strategy considering the component design, tessellation and control methods.
