summary This paper describes a recently concluded graduate seminar which tested how form-generative design tactics of algorithmic work could be productively brought to bear on the conceptual analysis of existing buildings. The seminar did not seek to optimize performance or aesthetic value but simply to query the mechanics and consequences of translation as an act. Seminar participants mined existing buildings as sources for parametric rule-sets which were subsequently applied to varying media fields (e. g., physical materials, text, and graphics). This application revealed that specific media resist certain kinds of translation. This peculiar resistance suggested that characteristics of architecture exist which might broadly be called untranslatable.

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 ‘tagging’) and assignment of various other attributes to model objects have significant limitations – especially those arising from general problems of language, ontology and standardization, as well as but distinct from issues of interoperability – 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 – as an alternative or complement to common assigned-attribute-based methods – and on the other hand visual analytic techniques – in contrast to existing, relatively static tabular and "physical" views – 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’ positive present performance and some of their shortcomings, as well as indicating directions for future research concerning the methods’ 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’ present levels of complexity and especially with respect to their anticipated increasing complexity in future.

title Gains, losses and limitations in designing parametrically: A critical reflection of an architectural design studio in China
doi https://doi.org/10.52842/conf.caadria.2011.569
source Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 569-578
summary This paper argues that learning to design parametrically in the architectural studio entails gains but also losses, since the parametric design approach tends to and encourage certain patterns of thought while discouraging others. This investigation complements previous research focusing mostly on technological aspects. Based on observational data from a parametric design studio in China, this paper discusses how parametric designing can pose challenges to existing design values and approaches, specifically within a Chinese context. It further draws attention to the limitations of parametric designing, which in the observed cases required both students and teachers to break and extend parametric models besides and beyond parametric variation to make them work architecturally. This paper aims to inform educators employing parametric designing in their architectural design studios as well as researchers who examine such studios.

title Mass-Customization in the Design of 4,000 Bus Stops
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. 265-278.
summary In Hawaii, ‚"TheBus‚" has been a main transportation system since 1971. Considering the high cost of living in Hawaii and the absence of a rail system, the use of ‚"TheBus‚" has been an instrumental vein of the city life in Honolulu with rhythmical pauses at about 4,000 bus stops in Honolulu. However, existing undifferentiated bus stops are developed from a cost effective mass production system so that they have been problematic for satisfying specific needs from various site conditions. In this research, an integrated computational method of mass-customization for designing 4,000 bus stops is introduced. According to various site conditions, the design of each bus stop is customized. Unlike the mass‚Äêproduced bus stops commonly seen in cities today, the proposed computational method in this paper produces bus stop design outcomes that fit into the physical characteristics of the location in which they are installed. Mass-customization allows for the creation and production of unique or similar buildings and building components, differentiated through digitally‚Äêcontrolled variation (Kolarevic, 2003). The employment of a computational mass‚Äêcustomization in architectural design extends the boundary of design solutions to the satisfaction of multi-objective requirements and unlimited freedom to search alternative solutions (Duarte, 2001; Caldas, 2006). The computational method developed in this paper consists of 1) definition of a prototype, 2) parametric variation, 3) manual deformation, and 4) simulation based deformation. The definition of a prototype is the development of a basic design to be transformed for satisfying various conditions given from a site. In this paper, the bus stop prototype is developed from the analysis of more than 300 bus stops and the categorization of the existing bus stops according to their physical conditions, contextual conditions, climatic conditions, and existing amenities. Based upon the outcome of the analysis, the design variables of a bus stop prototype are defined. Those design variables then guide the basic physical parameters for changing the physical configuration of the prototype according to a given site. From this, many possible design outcomes are generated as instances for further developments. The process of manual deformation is where the designer employs its intuition to develop the selected parametric variation. The designer is compelled to think about the possible implication derived from formal variation. This optional process allows every design decision to have a creative solution from an individual designer with an incidental quality in aesthetics, but substantiated functional quality. Finally the deformation of the selection is guided and controlled by the influence of sun direction/ exposure to the selection. The simulation based deformation starts with the movement of the sun as the trigger for generating the variations of the bus stop prototype. The implementation of the computational method was made within the combination of MEL (Maya Enbedded Language), autodesk MAYA and Ecotect environment.

title Automated Cost Analysis of Concept Design BIM Models
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. 403-418.
summary AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs. Building parameters are integrated in the report to provide insight on the variations among design alternatives.

title Performative architecture as a guideline for transformation: Defense Line of Amsterdam
doi https://doi.org/10.52842/conf.ecaade.2011.501
source RESPECTING FRAGILE PLACES [29th eCAADe Conference Proceedings / ISBN 978-9-4912070-1-3], University of Ljubljana, Faculty of Architecture (Slovenia) 21-24 September 2011, pp.501-510
summary Performance as an architectural design paradigm has been emerging during the recent years. We have developed an understanding that we formalized as a taxonomy for performative architecture that considers performance from three points of view: health, safety and security performance; functional and efficiency performance; and psychological, social, cultural, and esthetic performance. This paper focuses on a design project that explores these ideas as a performative architecture proposal. The project focuses on the architectural transformation of the Defense Line of Amsterdam, 41 forts, as a green belt. This transformation considers a holistic approach of defining a general method and guideline. We developed a series of parametric models for the definition and generation of designs. The first model computes an urbanization level for each fort. Consequently, models are developed in 4 stages: regional design, urban design, building design, and production of a scale model, and these are applied in an iterative manner to reach design outcomes for the project.

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.

title Thonet Chairs Design Grammar: a Step Towards the Mass Customization of Furniture
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. 181-200.
summary The paper presents the first phase of research currently under development that is focused on encoding Thonet design style into a generative design system using a shape grammar. The ultimate goal of the work is the design and production of customizable chairs using computer assisted tools, establishing a feasible practical model of the paradigm of mass customization (Davis, 1987). The current research step encompasses the following three steps: (1) codification of the rules describing Thonet design style into a shape grammar; (2) implementing the grammar into a computer tool as parametric design; and (3) rapid prototyping of customized chair designs within the style. Future phases will address the transformation of the Thonet’s grammar to create a new style and the production of real chair designs in this style using computer aided manufacturing. Beginning in the 1830’s, Austrian furniture designer Michael Thonet began experimenting with forming steam beech, in order to produce lighter furniture using fewer components, when compared with the standards of the time. Using the same construction principles and standardized elements, Thonet produced different chairs designs with a strong formal resemblance, creating his own design language. The kit assembly principle, the reduced number of elements, industrial efficiency, and the modular approach to furniture design as a system of interchangeable elements that may be used to assemble different objects enable him to become a pioneer of mass production (Noblet, 1993). The most paradigmatic example of the described vision of furniture design is the chair No. 14 produced in 1858, composed of six structural elements. Due to its simplicity, lightness, ability to be stored in flat and cubic packaging for individual of collective transportation, respectively, No. 14 became one of the most sold chairs worldwide, and it is still in production nowadays. Iconic examples of mass production are formally studied to provide insights to mass customization studies. The study of the shape grammar for the generation of Thonet chairs aimed to ensure rules that would make possible the reproduction of the selected corpus, as well as allow for the generation of new chairs within the developed grammar. Due to the wide variety of Thonet chairs, six chairs were randomly chosen to infer the grammar and then this was fine tuned by checking whether it could account for the generation of other designs not in the original corpus. Shape grammars (Stiny and Gips, 1972) have been used with sucesss both in the analysis as in the synthesis of designs at different scales, from product design to building and urban design. In particular, the use of shape grammars has been efficient in the characterization of objects’ styles and in the generation of new designs within the analyzed style, and it makes design rules amenable to computers implementation (Duarte, 2005). The literature includes one other example of a grammar for chair design by Knight (1980). In the second step of the current research phase, the outlined shape grammar was implemented into a computer program, to assist the designer in conceiving and producing customized chairs using a digital design process. This implementation was developed in Catia by converting the grammar into an equivalent parametric design model. In the third phase, physical models of existing and new chair designs were produced using rapid prototyping. The paper describes the grammar, its computer implementation as a parametric model, and the rapid prototyping of physical models. The generative potential of the proposed digital process is discussed in the context of enabling the mass customization of furniture. The role of the furniture designer in the new paradigm and ideas for further work also are discussed.

title Analysis model for incremental precision along design stages

source Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 19-18
summary With current energy analysis tools, architects and engineers cannot rely on the results of energy analyses because they do not report their level of precision. In addition, current tools also do not deliver feedback in real time. Thus, this research addresses the challenge of obtaining feedback in real-time while gradually increasing precision along design stages. For this purpose, this study merges parametric modelling (PM) technologies and the performance-based design (PBD) paradigm into a general design model. The model is based on a parametric and an energy analysis model that share the parameters of a building. The modular architecture of the model involves four main function types: an input processor, optional analysis functions embedding different calculation methods, a decision-maker, and a report generator function. For every step of the design evolution, the decisionmaker function generates a specific tree of analysis functions.

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 Using 3D Design Software, BIM and Game Engines for Architectural Historical Reconstruction
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. 493-509.
summary The use of digital tools has become a tremendous aid in the creation of digital, historical reconstructions of architectural projects. Regular visualization techniques have been used for quite some time and they still pose interesting approaches, such as following cinematic techniques [1]. While common visualizations focus on pre-rendered graphics, it is possible to apply Game Engines [2] for real-time architectural visualization, as witnessed by [3] and [4]. In the course of our teaching and research efforts, we have collected experience with several visualization and modeling techniques, including the use of gaming engines. While the modeling of qualitative geometry for use in regular visualization already poses an elaborate effort, the preparation of models for different uses is often not trivial. Most modeling systems only support the creation of models for a single amount of detail, whereas an optimized model for a real-time system will have fairly different constraints when compared to non-real-time models for photorealistic rendering and animation. The use of parametric methods is one usable approach to tackle this complexity, as illustrated in [4]. One of the major advantages of using parametric approaches lies precisely in the possibility of using a single model to generate different geometry with control over the amount of detail. We explicitly tackle this in a Building Information Modeling (BIM) context, as to support much more than purely 3D geometry and visualization purposes. An integrated approach allows the same model to be used for technical drawings in 2D and an optimized 3D model in varying levels of detail for different visualization purposes. However, while most Building Information Modeling applications are targeted to current architectural practice, they seldom provide sufficient content for the recreation of historical models. This thus requires an extensive library of parametric, custom objects to be used and re-used for historically accurate models, which can serve multiple purposes. Finally, the approach towards the historical resources also poses interpretation problems, which we tackled using a reasonably straightforward set up of an information database, collecting facts and accuracies. This helps in the visualization of color-coded 3D models, depicting the accuracy of the model, which is a valuable graphical approach to discuss and communicate information about the historical study in an appealing format. This article will present the results of different reconstruction case studies, using a variety of design applications and discuss the inherent complexity and limitations in the process of translating an active, evolving model into an environment suitable for use in a real-time system. Especially workflow issues are identified, as the translation of the model into the game engine should be repeated several times, when the model is further refined and adapted. This used to involve a large amount of repetitive work, but the current crop of game engines have much better approaches to manage the updating of the geometry.

summary Robots are gaining popularity in architecture. Snøhetta has recently purchased their own industrial robot, becoming one of the first architectural offices to adopt robot technology. As more and more architects are exposed to robotic fabrication, the need for easy interoperability, integration into architectural design tools and general accessibility will increase. Architects are discovering that industrial robots are much more than kinematic machines for stacking bricks, welding or milling - they are highly multifunctional and can be used for a huge variety of tasks. However, industry standard software does not provide easy solutions for allowing direct robot control right from CAAD (Computer Aided Architectural Design) systems. In this paper we will discuss existing methods of programming industrial robots, published architectural results (Gramazio and Kohler 2008) and the design of a new user interface that allows intuitive control of parametric designs and customized robotic mass production, by integrating CAM (Computer Aided Manufacturing) functions into CAAD.

summary The international architecture of the last decades has examples of works and architectural projects presented graphic from the two-dimensional unfolding of three-dimensional folded surfaces. These valuable individual experiences have not represented generalized strategies that can be transferred to the professional practice and to architectural education. This article uses results of more than 10 workshops (with Unfolding and Folding methodologies) developed in Chile, Argentina and Brazil to build up a pedagogy for the project that makes it possible to investigate the spatial and material properties of folded compositions in Architecture. It proposes to review and update project instruments through the incorporation of Parametric Design; 3D origami software and Digital Manufacturing.

title Parametric Design with Standard Elements for Non-Standard Architecture
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. 119-132.
summary The development of non-standard architecture is often combined with the use of non-standard elements. But for economical or sustainable reasons, the use of standard elements may be particularly useful. The introduction of standard elements adapted to geometries far from parallelepipeds and freely designed raises a specific problem. The aim of this paper is to explore some ways offered by computing tools in order to help architects in the design process of non-standard shapes using standard elements. An approach is proposed for a specific typology of systems composed of constant length elements. The method used herein is based on parametric modeling associated with constraint resolution algorithms. (short abstract because full paper already written)

title Parametric modelling and design processes: Exploringsynthesis and evaluation using a Function-Behaviour-Structure perspective

summary In an attempt to extend our understanding of the design process in the context of computational parametric design tools, this paper explores the relationship between and interaction of synthesis and evaluation. In establishing the importance of their coupling in parametric design the paper then explores its consequence on the design process relative to existing models of designing. A tension between designing as planning, search and exploration in parametric design is highlighted together with a conceptual framework, which draws from a situated Function-Behaviour-Structure model of design. The purpose of the framework is to facilitate these different modes of designing and is targeted at the use of parametric tools.

title Untangling Parametric Schemata: Enhancing Collaboration Through Modular Programming
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. 55-68.
summary Presently, collaboration is difficult on large and complex parametric models due to the illegibility of unstructured schemata. This lack of legibility makes it hard for an outside author to understand the model, reducing their ability to edit and share the model. This paper investigates whether the legibility of parametric models is enhanced through restructuring the schema with modular programming principles. During a series of thinking-aloud interviews, designers asked to describe the function of unfamiliar schemata could consistently better comprehend the schemata structured with modular principles. Modular programming is found to be a small change to parametric modelling that derives clear benefits in terms of legibility, particularly when the model is large and used in a collaborative environment.

title Designing responsive architecture: Mediating analogue and digital modelling in the studio
doi https://doi.org/10.52842/conf.caadria.2011.155

summary Prototyping digitally responsive architecture requires that architects know how to program and design electronics. Normally they don’t. The challenge for teachers is to teach these skills whilst maintaining a focus on the design potentials of responsive architecture. One method is to teach students to use Input-Output-Process (IPO) diagrams and parametric modelling as pathways into the logic of responsive architecture. The paper discusses the work of students taught this way during a semester long elective. Our analysis shows that IPO diagrams lead to reactive architecture, which matches the current technical limitations of responsive architecture. We argue that mediating analogue and digital models is an essential aspect to successful responsive architecture.
