summary This study reports the activities of 80 second year architecture students at Victoria University, Wellington, New Zealand for the duration of a single trimester. A central theme in this studio is the framing of day-lighting problems into a quantifiable investigation and then addressing these through the use of digital modelling and simulation tools. This study offers an insight to undergraduate architecture students’ negotiation of digital design spaces and asks the question of how the knowledge of skill-based specialist tasks are extensible to core design studio.The mass education within a University environment of such specialist skill based techniques allows for an insight to the negotiation of quantitative and qualitative design criteria. The issue of learning skill based tasks at university level is a pertinent topic of study as the critique of such techniques is implicit to the holistic education of Architects but the level of this critique can vary greatly. This question also highlights the challenges faced to improving the design education approaches to computational thinking and applications.

title A Computer Aided Design Model for Climate Responsive Dwelling Roof
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. 315-332.
summary Computer-Aided Design models have generated new possibilities in the sustainable design of buildings. Computer models assisting different aspects of architectural design have been developed and used for several decades. A review of contributions of computing to architectural design is given by Gero. Most of the conventional simulation computer programs do not actively support design development and optimization, specially at the formative design stages. It is well established that most decisions that affect comfort and building energy use occur during the formative design stages of the project. Furthermore, the efforts required to implement those decisions at the beginning of the design process are small compared to the effort that would be necessary later on in the design process. Therefore, if sustainable design issues are going to receive an appropriate level of consideration at the beginning of the design process, they must be presented in a way which is useful to the architect and fits with other things the architect is considering at that time. Design is seen as a problem-solving process of searching through a space of design solutions. The process of finding a solution to a design problem involves, identifying one or more objectives, making design decisions based on the objectives, predicting and evaluating the performance to find the acceptable decisions. Each of these activities can be performed inside or outside the formal model. In designing a roof, an architect or building designer has to make many decisions on the materials. The arrangement of these materials determines the aesthetic appearance of the roof and the house. Other considerations that affect the choice of roofing materials are thermal performance, rain, fire protection, cost, availability and maintenance. Recyclability of materials, hazardous materials, life-cycle expectancy, solutions, and design options as they relate to the environment also need to be considered. Consequently, the design of roof has become quite a complex and multifaceted problem. The principal need is for a direct design aid which can generate feasible solutions and tradeoff performance in conflicting requirements and prescribe the optimum solution. This paper presents a conceptual Computer Aided Design model for dwelling roof. It is based on generation and optimization paradigms of Computer Aided Design; which is diametrically opposite to conventional simulation. The design of roof (design goal) can be defined in terms of design objective as "control radiant and conduction heat." This objective must be satisfied to achieve the design goal. The performance variables, such as roof ceiling surface temperature or new thermal performance index (TPI*) must acquire values within certain ranges which will satisfy the objective. Given the required inputs, this computer model automatically generates prescriptive quantitative information to design roof to achieve optimum thermal comfort in warm humid tropics. The model first generates feasible solutions based on the decision rules; next it evaluates the thermal performance of the roof taking into account design variables related to the building’s roof and finally it applies numerical optimization techniques to automatically determine the optimum design variables, which achieve the best thermal performance. The rational and methodology used to develop the proposed model is outlined and the implementation of model is described with examples for climatic and technological contexts of India and Australia.

title Spatial Experience in Real & Virtual Environment as an Urban Design Tool
source Projecting Spaces [Proceedings of the 9th European Architectural Endoscopy Association Conference / ISBN 978-3-942411-31-8 ], pp. 59-64
summary The innovations of information technologies and the new possibilities of multimedia exploitation in the realm of architectural design and education are supporting the development of image communication methods on the basis of interactivity. The creative process of searching and decision-making in the urban design studio of our Faculty is supported by spatial modeling methods. The draft is sketched in modeling material on a working model. From the didactic point of view, relevant are mainly those phases, in which is possible, in the imaginative way, to support the searching and decision making process with the aim to test, compare and continuously evaluate the fulfillment of the hypothetic intentions of the solution responsibilities. The model becomes an interactive medium of cooperation between teacher and the working group of students. From the view of design crystallization, the dominant phases, in the creative process, are examining, verification, and simulation. The alternatives of material-compositional content and the spatial performance charts of modeled physical structure are verifying and the visual experience of the anticipated urban environment is simulated by the author, but also through the future client’s eyes. The alternation of the composition’s spatial configurations is generally appreciated by the static visual verification in the endoscopic horizon like the architectural spatial studies. The effective method of the progress generates a creative atmosphere for the generative thinking and design. The laboratory simulation of spatial experiences and their evaluation is performed following the perception psychology relations. The simulation of digestion of the new spatial reality intervenes the customer’s identification and guides to subjective approaches towards the quality and complexity of the formed environment. The simulation is performed in motion in order to be able to anticipate the dynamic continuity of subjective spatial imagination. The induced atmosphere will direct the evaluational attitudes of authors on comparison and selection of the successful alternatives. In our fee, we will present the demonstrations of selected static and dynamic notations of image sequences prepared in our laboratory. The presentations have been created in order to analyze, verify and offer imaginative support to creative findings in result of fulfilling the studio design tasks in the educational process. The main one is the design of urban spatial structures. The laboratory methodology is in the first place oriented on the analogue-digital procedures of "endoscope" model simulation. At the same time it also explores and looks for new unconventional forms of visual communication or archiving as imagination support to specialist and laymen participants in creative, valorization and approval processes.

title Designing a Systematic Experiment to Investigate the Effect of Ambient Smell on Human Emotions in the Indoor Space; Introducing a Mixed-Method Approach
source Proceedings of the 2023 DigitalFUTURES The 5st International Conference on Computational Design and Robotic Fabrication (CDRF 2023)
doi https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_20
summary Studies have indicated that built environments affect all aspects of human life such as emotion, perception, behavior, health, and well-being (Cooper et al. 2011). Built environments are formed from the combination and juxtaposition of visible and invisible environmental variables. In recent years, common techniques such as virtual reality, augmented reality, digital twins, and artificial intelligence have enabled researchers in the field of architecture and urban design to simulate environmental conditions to investigate the impacts of environmental variables on humans. However, the studies conducted in this field of human comfort are mostly focused on the impact of environmental variables such as form, temperature, humidity, and sound, and in fewer studies, up-to-date methods and technologies have been used to simulate and investigate the impact of smell on humans. Most of the studies that have investigated the effect of ambient smell on humans, carried out in the discipline of architecture and urban design, have used traditional tools and methods (questionnaire, interview, observation) rather than advanced technology and tools drawing on neuroscientific knowledge and technique to measure the effectiveness of the ambient smell on human. They have used unmasked scents or real-world environments rather than being able to simulate environmental conditions. This article highlights the significance and necessity of employing simulation methods to investigate the impact of environmental smells on humans. Additionally, it presents the methodology of an experiment for studying the effect of indoor environment smells (with a case study of an office environment in the initial phases) on human emotions, utilizing a mixed-method approach. Analysis of some parts of the data from this experiment showed that exposure to the fragrance of the jasmine flower pleasant (flower) and the odor of the rotten orange peel (unpleasant) can cause changes in the electroencephalography (EEG) power across different bands among participants.

title Colour-code models: The concept of spatial network
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. 707-716
doi https://doi.org/10.52842/conf.caadria.2011.707
summary The main goal for the architects or planners is to understand a perspective of the user. The foundation of the design process is to create buildings and environments, which will be both innovative and functional for all types of users, including adults and children. While planning the environments for children the particular aspects should be considered. The important questions are: What kind of contact does child have with the city, urban places and buildings? How does the child construct the picture of the city? What kind of urban or architectural spaces contributes to the relation that a child has with the environment? Most of the previous studies concentrating on creation of spaces for children have focused on the perspectives that have adults. According to CAADRIA 2010 paper, the objective of our study was to “learn about” (get to know the) children’s perception of everyday places. The main goal of the project was to define an appropriate tool for the design process. We identified three elements, which were considered to be the most important for child’s identification with environment: home, school, and the journey from home to school. For this purpose, children living in a residential community in Bangkok were surveyed. Contrariwise to the quantitative approach (Neisch, 2010), the concept of Colour – Code Models of space propose a qualitative development of this research – a graphic language which allow to understand the children’s spatial world, the novel way to analyze and present space, useful for educate architects and planners.

title Interpreting Digital Heritage: A Conceptual Model with End-Users' Perspective
source International Journal of Architectural Computing vol. 9 - no. 1, 99-114
summary Present virtual heritage projects are mostly focused either on ‘process’ or ‘product’ but rarely consider ‘users’ (end-users' perception of the content) with project contents predominantly developed with an ‘ocular-centric’ tendency. There is no significant interpretation method or principle for interpreting digital heritage like other disciplines such as archaeology. This paper argues that, for better interpretation and experience of a digital heritage site, a comprehensive interpretation method is required, which should address end-users with various background, overcome the linearity in narrative level and subjectiveness in content creation. This paper also argues that instead of predetermined instructional sequences or descriptive interpretation, the interaction setting can be participatory and contributive, where the end-users and environment may engage in ‘dialogic-interaction’. In terms of methodology, ‘Interpretation’ is first conceptualized by assimilating definitions from various heritage scholars and interpretation organizations. Notions of interpretation-practice and level of interaction are identified from reviewing some online digital heritage projects. By identifying weaknesses, this paper finally proposes a conceptual model for developing a comprehensive interpretation method for future digital heritage projects.

title Backtracking Decisions within a Design Process: a Way of Enhancing the Designer's Thought Process and Creativity
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. 573-587.
summary This paper proposes a way computer sciences could contribute to stimulate the designer’s reflexive thought. We explore the possibility of making use of backtracking devices in order to formalize the designer’s thought process. Design, as a process of creating an object, cannot be represented by means of a linear timeline. Accordingly, the backtracking processes we are discussing here are not based on a linear model but rather on a non-linear structure. Beyond the notion of undoing and redoing commands within CAD packages, the backtracking process is seen as a way to explore and record several alternate options. The branches of the non-linear model can be seen as pathways made of sequential decisions. The designer creates and explores these pathways while making tentative moves towards an architectural solution. Within the design process, backtracking enables the designer to establish and act on a network of interrelated decisions. This notion is fundamental. It is quite obvious that information, in order to be meaningful, must occupy a specific place within an informational network. A data, separated from its context, is devoid of interest. By the same token, a decision takes on significance solely in combination with other decisions. In this paper, we examine what kinds of decisions are involved within a design process, how they are connected, and what could be the best ways to formalize the relationships. Our goal is to experiment ways that could enable the designer and his/her collaborators to get a clearer mental picture of the network of decisions aforementioned. The non-linear model can be seen as a graph structure. The user moves wherever he/she wants through the branches of the structure to establish the network of decisions or to get reacquainted with a previous design process. As a matter of fact, it can act in both ways: to reassess or to confirm a decision. On the one hand, the designer can go back to previous states, reconsider past choices, and eventually modify them. On the other hand, he/she can move forward and revisit a given sequence of decisions, so as to recapture the essence of a previous design process. It goes without saying that knowledge regarding the design process is constructed by the designer from his/her own experiences. Since the designer’s perception evolves as time goes by, the network of decisions constitutes a model that is continuously questioned and restructured. The designer does not elaborate solely an architectural object, but also an evolving model formalizing the way he/she achieved his/her aim. As Le Moigne (1995) pointed out, the model itself produces knowledge; afterwards, the designer can examine it so as to get a clearer mental picture of his/her own cognitive processes. Furthermore, it can be used by his/her collaborators in order to understand which thread of ideas led the designer to a given visual result, and eventually resume or reorient the design process. In addition to reflecting on the ideological implications inherent to this questioning, we take into account the feasibility of such a research project. From a more technical point of view, in this paper we will describe how we plane to take up the challenge of elaborating a digital environment enabling backtracking processes within graph structures. Furthermore, we will explain how we plane to test the first trial version of the new environment with potential users so as to observe how they respond to it. These experiments will be conducted in order to verify to what extend the methods we are proposing are able to i) enhance the designer’s creativity and ii) increase our understanding of designer’s thought process.

source SIGraDi 2011 [Proceedings of the 15th Iberoamerican Congress of Digital Graphics] Argentina - Santa Fe 16-18 November 2011, pp. 530-533
summary This paper presents a methodology to augment acoustically the experience of the urban environment by mapping its fundamental spatial elements and translating them to sound and music. The methodology can be applied at any given path of an urban network to generate its acoustical representation with sounds produced by appropriately chosen musical instruments. The objective is twofold. On the one hand it targets the amelioration of the urban experience of people with impaired vision while on the other it offers a more synaesthetic spatial perception to all those who rely mostly on their retinal understanding of the environment.

summary Ambient displays allow physical space to be transformed into a dynamic and ever-changing environment in which boundaries are dissolved. However, it is likely that the incorporation of such digital elements affects people’s perception and understanding of space. In this particular study, a series of experiments were conducted to examine how a skewed perspective projection via an ambient display influences people’s navigation in public spaces. The findings are then presented showing how the participants’ responded to the presence of the skewed projection and the effects on the movement patterns. This study discusses the ability of an ambient display to influence navigation paths and suggests that a projection with skewed perspective can determine the creation of new movement patterns.

summary Through their daily interactions with the built environment, people with disabilities become able to appreciate spatial qualities or detect obstacles that architects may not be attuned to. This observation motivated us to explore scenarios for involving people with sensory disabilities as experts in the design process. An architecture office participating in a real-world design competition is teamed up with two blind persons. The design process is studied in real time through a team ethnography. The analysis in this paper focuses on the mediating aspects of objects in the actions, perception and cognition in one collaborative design meeting in particular. In general, disability situations can teach us something about fixed ways of doing by making perceivable, or questioning practices that seem self-evident. In this particular situation, the blind person’s involvement in a design meeting that relies heavily on representational artifacts, makes perceivable or questions everyday practices in architects’ design process that are taken for granted. Examples include knowing and indicating to others where design elements are on the site, knowing what design element is being talked about, holding the element and its environment ‘in place’, or spatially exploring the design’s spatial configuration. As such, our study shows that exploring inclusivity ‘upstream’, i.e. in the design process, may contribute not only to inclusive design, but also to a more articulate understanding of the working of mediating objects and their use in architects’ design processes tout court.

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.

summary In architecture various approaches have been developed do deal with changing demands on the building. The most recent development is interactive architecture. In this paper we aim to outline what interactive architecture is. First we define the type of performance behavior that an interactive building or environment has. Following, we consider the relation between the system and the user. We derive four types of relations, characterized as “perfect butler,” “partner,” “environmental,” and “wizard.” Interactive systems are composed of sensors, controllers, actuators, and materials. Various degrees of interactivity can be achieved with such systems, ranging from passive, reactive, autonomous, to agent systems. Complete with earlier discussion of design methods this provides the range of aspects that should be considered when designing interactive architecture.

title Behavior-based Computational Design Methodologies: Integrative processes for force defined material structures
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. 82-89
doi https://doi.org/10.52842/conf.acadia.2011.082
summary With the introduction of physics-based algorithms and modeling environments, design processes have been shifting from the representation of materiality to the simulation of approximate material descriptions. Such computational processes are based upon enacting physical and material behavior, such as gravity, drag, tension, bending, and inflation, within a generative modeling environment. What is often lacking from this strategy is an overall understanding of computational design; that information of increasing value and precision is generated through the development and iterative execution of specific principles and integrative mechanisms. The value of a physics-based modeling method as an information engine is often overlooked, though, as they are primarily utilized for developing representational diagrams or static geometry – inevitably translated to function outside of the physical bounds and parameters defined with the modeling process. The definition of computational design provides a link between process and a larger approach towards architecture – an integrative behavior-based process which develops dynamic specific architectural systems interrelated in their material, spatial, and environmental nature. This paper, focusing on material integration, describes the relation of a computational design approach and the technical framework for a behavior-based integrative process. The application is in the development of complex tension-active architectural systems. The material behavior of tensile meshes and surfaces is integrated and algorithmically calibrated to allow for complex geometries to be materialized as physical systems. Ultimately, this research proposes a computational structure by which material and other sorts of spatial or structural behaviors can be activated within a generative design environment.

doi https://doi.org/10.52842/conf.acadia.2012.047
summary Important progress towards the development of a system that enables multi-criteria design optimisation has recently been demonstrated during a research collaboration between Autodesk’s DesignScript development team, the University of Bath and the engineering consultancy Buro Happold. This involved integrating aspects of the Robot Structural Analysis application, aspects of the Ecotect building performance application and a specialist form finding solver called SMART Form (developed by Buro Happold) with DesignScript to create a single computation environment. This environment is intended for the generation and evaluation of building designs against both structural and building performance criteria, with the aim of expediently supporting computational optimisation and decision making processes that integrate across multiple design and engineering disciplines. A framework was developed to enable the integration of modeling environments with analysis and process control, based on the authors’ case studies and experience of applied performance driven design in practice. This more generalised approach (implemented in DesignScript) enables different designers and engineers to selectively configure geometry definition, form finding, analysis and simulation tools in an open-ended system without enforcing any predefined workflows or anticipating specific design strategies and allows for a full range of optimisation and decision making processes to be explored. This system has been demonstrated to practitioners during the Design Modeling Symposium, Berlin in 2011 and feedback from this has suggested further development.

title Radicalism vs. Consistency - The Cyber Influence on Individuals’ Non-Routine Uses in the Heritage Public Spaces of Cairo
source Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 451-460
summary Since the emergence of the concept of user-generated content websites – Web 2.0, Internet communications have developed as a powerful personal and social phenomenon. Many Internet applications have become partially or entirely related to the concept of social network; and cyberspace has become a space about ‘us’ not ‘where’ we are. This paper investigates the theoretical grounds of the effect of cyber experience on changing the individuals’ uses of the public spaces, and sustaining this change through maintaining the ties and reciprocal influence between actions in physical and cyber spaces. It aims at examining the impact of cyber territories on the perception, definition and effectiveness of personal space within different circumstances; and its role in changing the uses of spaces where people used to act habitually. The personal space, here, will be represented as the core of both: change and consistency – the space of bridging the reciprocal effect of cyber and physical counterparts, which is transformed through the experience of physical events mediated into the cyberspace. The paper is part of a study which looks at the case of Tahrir Square during the Egyptian political movement in 2011. We will compare the activists’ actions and practices in the Square during different events of non-routine use of the square and its surroundings. The case study will show the level of consistency in the features of the produced personal space within different waves of the revolutionary actions for all that different circumstances, motivations and results.

summary The paper discusses the following problem: How can digital technology are integrated with urban composition teaching to provide a better understanding of the aesthetical and emotional aspects of the city? It argues for the current need for an integration of computer modelling and the approaches developed form the work of K. Lynch, G. Cullen, R. Krier, F. Ching. The paper is based on the experience in design studio teaching and an experiment completed with students. The exercise shows the students that different spatial organization may cause different emotions according to the treatment of space-defining elements. The paper presents the background and context as well as describes the experimental environment and the student work.

title Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
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. 247-264.
summary The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called “gingerbread houses”, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

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 A window to the autism: the political role of the difference of an objectile in the homogeneous school
source SIGraDi 2018 [Proceedings of the 22nd Conference of the Iberoamerican Society of Digital Graphics - ISSN: 2318-6968] Brazil, São Carlos 7 - 9 November 2018, pp. 848-853
summary This paper approaches the insertion of an objectile in the homogeneous space of a school, looking to bring flexibility and responsiveness to assist a user with Autism Spectrum Disorder (ASD). The research concerns with photosensitivity, a problem faced by almost 25% of the children with autism (Miller-Horn; Spence; Takeoka, 2011). The study is based on the theories for ASD environments that speak of ‘sensorial perception’ and ‘thinking with imagery’ (Mostafa, 2008), and the coexistence of Sensory Design Theory and Neuro-Typical Method (Pomana, 2015). The result consists of a gadget developed in MIT App Inventor tool and a curtain that interact responsively through an Arduino code, for a new connection between the user and his surroundings.
