title	Synthesizing Design Performance: An Evolutionary Approach to Multidisciplinary Design Search
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. 67-75

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.

title	Performative Topologies: An Evolutionary Shape Optimization Framework for Daylighting Performance Coupling a Particle-Spring System With an Energy Simulation Tool
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. 479-490

summary	This paper develops a methodological approach for use in design practice which combines an external simulation tool (EnergyPlus™) with an evo-lutionary optimisation strategy for the form-finding of complex fenestra-tion systems. On one hand, based on previous research, it presents a novel approach for the shape morphogenesis that exploits a generative algorithm technique to control a limited set of parameters whilst on the other hand it facilitates the integration of a simulation tool capable of handling increasing levels of complexity with greater data interoperabil-ity. In doing so it will argue the heuristic potential of the proposed meth-od in aiding the designers’ decision making whilst increasing the formal possibilities of their final design solutions.

title	Availability of a distributed and synchronised type meeting by using cloud computing type VR for spatial design study
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 203–210

summary	The mobility of people's activities, and cloud computing technologies are becoming advanced in the modern age of information and globalisation. This study describes the availability of discussing spatial design while sharing a 3-dimensional virtual space with stakeholders in a distributed and synchronised environment. First of all, a townscape design support system based on a cloud computing type VR system is constructed. Next, an experiment of a distributed and synchronised discussion of townscape design is executed with subjects who are specialists in the townscape design field. After the experiment, both qualitative mental evaluation and quantitative evaluation were carried out. The conclusions are as follows: 1. Users who use VR frequently and who use videoconferencing consider that the difference with face-to-face discussion is small. 2. A Moiré pattern may occur in a gradation picture. 3. The availability of distributed and synchronised discussions with cloud computing type VR is high.

title	3d Virtuality Sketching: Interactive 3d Sketching Based on Real Models in a Virtual Scene
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. 409-418

summary	Sketches and working models are without doubt one of the most widely used tools in the architect’s repertoire. In the early phases of the design process in particular, they represent an essential part of the exploration process. For the most part, however, sketching and model building are separate and sequential steps. This paper examines how both media can be linked to each other more effectively so that the design process is more continuous and the transition between the two media more fluid. Using a multi-touch table with additional 3D real-time object recognition, a prototypical system was developed and realised as part of a research project in which an interactive 3D sketching tool was linked with a real 3D working model.

title	Parallel Development of Parametric Design Models Using Subjunctive Dependency Graphs
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. 57-66
doi	https://doi.org/10.52842/conf.acadia.2012.057
summary	Exploring problems through multiple alternatives is a key aspect of design. In this paper, we present a prototype system as an extension to existing parametric CAD tools that enables parallel generation and editing of design alternatives. The system is built on two fundamental ideas. First, use of subjunctive dependency graphs enables simultaneous work on multiple design variations. These graphs capture and reveal complex data flow across alternative parametric CAD models. Second, prototype-based modeling provides a weak notion of inheritance enabling incremental description of differences between alternatives. The system is intended to be general enough to be used in different CAD platforms and other systems using graph-based modeling. The three basic system functions are definition of alternatives (variations) using prototype-based modeling, structural and parametric divergences of the prototypes, and interactive comparison. The goal of this research is consistent with the general qualities expected from any creativity support tools: enabling exploration and simultaneous development of variations.

title	Fabricating Sustainable Concrete Elements: A Physical Instantiation of the Marching Cubes Algorithm
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. 239-247
doi	https://doi.org/10.52842/conf.acadia.2012.239
summary	This paper explores how an algorithm designed to represent form can be made physical, and how this physical instantiation can be made to respond to a set of design imperatives. Specifically, the paper demonstrates how Marching Cubes (Lorensen and Cline 1987), an algorithm that extracts a polygonal mesh from a scalar field, can be used to initiate the design for a system of modular concrete armature elements that permit a large degree of variability using a small number of discrete parts. The design of these elements was developed in response to a close examination of Frank Lloyd Wright's Usonian Automatic system, an architecturally pertinent historical precedent. The fabricated results positively satisfy contemporary design criteria, including maximal formal freedom, optimal environmental performance, and minimal life-cycle costs.

title	Generation and Integration of an Aerodynamic Performance Data Base Within the Concept Design Phase of Tall Buildings
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. 87-96
doi	https://doi.org/10.52842/conf.acadia.2012.087
summary	Despite the fact that tall buildings are the most wind affected architectural typology, testing for aerodynamic performance is conducted during the later design phases well after the overall geometry has been developed. In this context, aerodynamic performance studies are limited to evaluating an existing design rather than a systematic performance study of design options driving form generation. Beyond constrains of time and cost of wind tunnel testing, which is still more reliable than Computational Fluid Dynamics (CFD) simulations for wind conditions around buildings, aerodynamic performance criteria lack an immediate interface with parametric design tools. This study details a framework for empirical data collection through wind tunnel testing of building mechatronic models and the expansion of the collected dataset by determining a mathematical interpolating model using an Artificial Neural Network (ANN) algorithm developing an Aerodynamic Performance Data Base (APDB). Frederick Keisler called the interacting of forces CO-REALITY, which he defined as The Science of Relationships. In the same article Keisler proclaims that the Form Follows Function is an outmoded understanding that design must demonstrate continuous variability in response to interactions of competing forces. This topographic space is both constant and fleeting where form is developed through the broadcasting of conflict and divergence as a system seeks balance and where one state of matter is passing by another; a decidedly fluid system. However, in spite of the fact that most of our environment consists of fluids or fluid reactions, instantaneous and geologic, natural and engineered, we have restricted ourselves to approaching the design of buildings and their interactions with the environment through solids, their properties and geometry; flow is considered well after the concept design stage and as validation of form. The research described herein explores alternative relations between the object and the flows around it as an iterative process, moving away from the traditional approach of Form Follows Function to Form Follows Flow.

summary	This paper concerns the current discourse on computer-aided design tools for architectural design. There are drawbacks of purely analytic design tools which hinder a system-level, end-effect oriented ideation. For instance, most freeform quadrilateral meshes are fully constrained and therefore not capable of folding. They can only fold under special circumstances – when their geometry satisfi es the conditions of over-constrained kinematics. However, such intent of folding cannot be captured using simple modeling based on parameters and constraints. Furthermore, algorithmization of mesh kinematics using formulas is infl exible, it cannot handle topological variations, and it inhibits the interactive control of the model. In this paper, a fuzzy logic algorithm which uses a goal-oriented, human-like reasoning to control the parametric model is proposed. The algorithm applies easily observable behaviors of the geometry to adjust the selected patches until the entire shell can be folded. The algorithm relies on designer-observable characteristics of motion rather than on formulaic representations. Such approach directs the designers’ focus on the desired outcome while avoiding the drawbacks of analytic modeling of complex kinematics.

title	Equalizing Daylight Distribution: Digital simulation and fabrication of optimized inner reflectors and bottom extractors for a light-duct

summary	The present paper explores the implementation of a light-duct in order to equalise daylight distribution in an office space. While the illuminance level near windows in a building tends to be higher than that necessary for the working environment, artificial lighting is often used to ensure that the workspace further away from the windows has the required level of illuminance. Equalising daylight distribution from the periphery to the inner part would thus provide signifi cant advantages for energy-efficient lighting as well as the fl exible and efficient use of offi ce space. In order to achieve this goal, anti-glare devices in the perimeter zone such as louvers and daylight distribution devices such as light-ducts are required. In this paper, we focus on light-ducts in the first instance, with an emphasis on their two key components for controlling the direction of daylight, namely inner reflectors and bottom extractors.

summary	A parametric urban design system integrating GIS data in a CAD environment is proposed as a platform for discussing urban plans providing flexibility and information access in an interactive fashion. The proposed system links calculations of urban indicators with the parameter manipulation of the layout geometry, therefore allowing for a systematic update of indicators according to design modifi cations. Hence, design may be fine-tuned in an informed manner enhancing the quality of design decisions.

title	Multi-criteria evolutionary optimisation of building enveloped during conceptual stages of design
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 497–506
doi	https://doi.org/10.52842/conf.caadria.2012.497
summary	This paper focuses on using evolutionary algorithms during conceptual stages of design process for multi-criteria optimisation of building envelopes. An experiment is carried out in optimising a panelled building envelope. The design scenario for the experiment is based on the scenario described in Shea et al. (2006) for the building envelope of the Media Centre Building in Paris. However, in their research, the optimisation process only allowed panel configuration to be optimised. In this paper, the task is to approach the optimisation of the envelope of the same building, assuming it to be in the early phases of the design process. The space of possible solutions is therefore assumed to be much wider, and as a result both external building form and internal layout of functional activities are allowed to vary. The performance intent of the experiment remains the same as that of Shea et al. (2006), which was to maximise daylight and minimise afternoon direct sun hours in the building at certain specific locations.

title	Data Sharing for Sustainable Building Assessment
source	International Journal of Architectural Computing vol. 10 - no. 4, 555-574
summary	Sustainable design assessment requires information, which is aggregated from different phases of a building design, and evaluated according to criteria specified in a ‘sustainable building rating system.’ In the architecture engineering and construction (AEC) domain much of the necessary information is available through open source data standards such as Industry Foundation Classes (IFC). However, no single standard that provides support for sustainability assessment completely suffices as a data structure. This paper explores the augmentation of the Construction Operations Building information exchange (COBie) model, as an intermediary data structure, to bridge between requirements of the Leadership in Energy and Environmental Design (LEED) rating system and a building information model. Development of a general framework for data sharing and information management for LEED assessments is illustrated through an implementation of a prototype using functional databases.The prototype checks and augments available data as needed, which is used to populate LEED submission templates.

doi	https://doi.org/10.52842/conf.acadia.2012.491
summary	Abstract Integral structural optimization and fabrication seeks the synthesis of two original approaches; that of topological optimization (TO) and robotic hotwire cutting (HWC). TO allows for the reduction of up to 70% of the volume of concrete to support a given structure. A strength of the method is that it allows to come up with structural designs that lie beyond the grasp of traditional means of design. A design space is a discretized volume, delimiting where the optimization will take place. The number of cells used to discretize the design space thus sets the resolution of the TO. While the approach of the application of TO as a constitutive design tool centers on structural aspects in the design phase, the outcome of this process are structures that cannot be realized within a conventional budget. As such the ensuing design is optimal in a narrow sense; whilst optimal structurally though, construction can be prove to be prohibitively expensive. This paper reports ongoing research efforts on the development of a cost effective methodology for the realization of TO concrete structures using HWC.

source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 47–56
doi	https://doi.org/10.52842/conf.caadria.2012.047
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.

summary	This article reports the experience of creating a support application for designing kinetic facades. The tool´s goal is the creation of a visual simulation system that permits full control over the movement of geometric patterns. In this case, we try to control the variation of polarized glasses used on architectural facades. The study presents a modeling technique of geometrical grids created and controlled by modular arithmetic operations. The programmed algorithm allows performing periodic geometric patterns. The research is aimed at formalizing a library of patterns and types of possible movements through ratings and an abstract symbolic representation.

summary	This paper is an account of the façade rationalisation strategy developed at Gehry Technologies for mitigating the tradeoffs between project constructability and the aesthetic implications of arranging flat panels over a complex surface. The strategy outlined was developed as the result of the digital building delivery of the Museo Soumaya façade in Mexico City designed by Fernando Romero LAR. This report documents the development process of a method for obtaining relevant construction information flows enabling the assembly of the façade system by a third-party sub-contractor in support of the façade system coordination. This report concludes on a method using bespoke software for extending the parametric modelling system Digital Project™ in the design support role of obtaining an aesthetically pleasing arrangement of flat hexagonal panels over a freeform surface.

title	Augmented Spatiality
source	International Journal of Architectural Computing vol. 10 - no. 2, 275-300
summary	Designers have long been concerned with new and visionary types of public space.With the advent of ubiquitous computing, architects and designers have become increasingly aware of the opportunities and challenges in designing spaces and everyday objects to support socially- oriented human interactions whether through spatial or technological means.This paper presents a novel transdiscplinary method for designing new interactive architectural prototypes that promote connectivity and social interactions in the public space in order to address specific agendas of urban interventions.The proposed method was evaluated in a pilot studio, in which students across various design and technical disciplines were invited to propose utopian socio- technological visions for a particular site and to develop their ideas into working architectural prototypes that could be installed at the chosen site and tested by the public.The open brief generated various responses and outcomes in eight projects, of which two are discussed in this paper.

title	Dynamic skin: Interacting with space: An inter-media interface between people and space
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 89–98
doi	https://doi.org/10.52842/conf.caadria.2012.089
summary	Space in its physical form provides the major architectural experience for the people inside the space. How people interact with their surrounding space dynamically is a noteworthy research topic. Architectural skin (or “skin” in this project) is the physical interface between people and their surroundings. The skin in this sense represents an inter-media that receive/sense the interactive behaviours of people and react back into space. Further, the skin needs to be mediated and reacted dynamically according to the interaction behaviours. With the case studies, the knowledge of skin design has achieved and then applied to develop three prototypes. In order to achieve the feasibility of skin design for dynamic skins, the multiple channels of input sensors are desired. Thus, a system called dynamic skin is proposed and details of process are evaluated. In order to incorporate the diverse scenario appeared in the cases and prototypes, a distributed system approach such as multi-agent system design is appealing to us. We propose a distributed dynamic skin platform that cannot only provide sufficient interaction between people and space, but also extending such space to the cloud and network.

summary	Loose granulates are a relevant yet rarely deployed architectural material system. Their significance lies in their capacity to combine fluid-like amorphousness with solid-like rigidity, resulting in potential architectural structures capable of continuous reconfi guration. In addition aggregates allow for functional grading. Especially if custom designed concave particles are used, full-scale architectural structures can be poured using a six-axis industrial robot, combining the precise travel of the emitter-head with the self-organizational capacity of granular substances. In this context, the paper proposes Rigid-Body Dynamics (RBD) simulations as a design-tool for the robotic pouring of loose granular structures. The notions of material and machine computation are introduced and RBD is explained in greater detail. A set of small tests is conducted to investigate the advantages and disadvantages of a specifi c RBD software. Conclusively, further areas of research are outlined.

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.
