title	Local Code: The Critical Use of Geographic Information Systems in Parametric Urban Design
source	ACADIA 10: LIFE in:formation, On Responsive Information and Variations in Architecture [Proceedings of the 30th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-4507-3471-4] New York 21-24 October, 2010), pp. 234-242

summary	Local Code uses geospatial analysis to identify thousands of publicly owned abandoned sites in major US cities, imagining this distributed, vacant landscape as a new urban system. Deploying GIS analysis in conjunction with parametric design software, a landscape proposal for each site is tailored to local conditions, optimizing thermal and hydrological performance to enhance local performance and enhance the whole city’s ecology. Relieving burdens on existing infrastructure, such a digitally mediated, dispersed system provides important opportunities for urban resilience and transformation. In a case study of San Francisco, the projects’ quantifiable effects on energy usage and stormwater remediation would eradicate 88-96% of the need for more expensive, centralized, sewer, and electrical upgrades. As a final, essential layer, the project proposes digital citizen participation to conceive a new, more public infrastructure as well.

title	Collaborative Parametric BIM
source	CAAD - Cities - Sustainability [5th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2010 / ISBN 978-1-907349-02-7], Fez (Morocco), 19-21 October 2010, pp. 127-134
summary	The paper will be focussing on a number of digital design tools used in [our groups credentials]. A new laboratory called […] is developed with Virtual Reality for collaborative architectural design. A brief description of the systems and how they are used to support a design team is given. Synchronic and a-synchronic, local and inter-local communication is made possible. Methods for introducing sustainability in the digital design process and user participation over the Internet will be discussed. The results of the author’s PhD research “Collaborative architectural design in virtual reality” are used to develop a new approach in which team members use their own specific software. Swarm design applications developed in Virtools are used at the start of a project. The objects in the swarm can be urban and architectural functional volumes. Examples of the first are houses, offices, factories, roads and water ways. Examples of the second are working, dining, shopping and waiting spaces. Relations between the functional volumes with or without constraints make the functional volumes swarm to find equilibrium. Everything is dynamic, meaning that relations and functional volumes can change any time. Alternatives can be developed using different values for these parameters and by top-down intervention. When the final global layout has been chosen, using a criteria matrix with sustainability criteria to be judged by all participants, including the future users, a next phase is started amongst professionals using parametric design software. A study into different types of parametric design software makes clear why object parametric software can be used for IFC based BIM, while the more interesting process parametric software can not. To make this clear a pragmatic description of the IFC format is given with a simple example of such a file. Future research will be proposed in which applications of different disciplines are connected through the application programming interfaces, while integrating as much as possible the building information and knowledge in the IFC format.

summary	Digital Fabrication and Hybrid Interface: Lessons in Agriculture :abstract Two vitally important fields of work in architecture and computing—in digital fabrication methods and in the development of interfaces between digital and analog systems—can find new forms in their combination with one another. Moreover, a recent such experiment in the production of landscape rather than building not only suggests a number of implications for architectural work, but of ecological, economic and urban structures that underlie the projects’s visible formal and aesthetic orders. This project, “Hyperculture: Earth as Interface,” studied the potential outcomes of modifying a commonly employed information infrastructure for the optimization of agricultural production throughout most of America’s heartland; and that same infrastructure’s latent flexibility to operate in both “read” and “write” modes, as a means for collaborative input and diversified, shared output. In the context of industrialized agriculture, this work not only negotiates seemingly contradictory demands with diametrically opposed ecological and social outcomes; but also shows the fabrication of landscape as suggestive of other, more architectural applications in the built environment. The Hyperculture project is sited within several contexts: industrial, geographically local, ecological, and within the digital protocols of landscape processing known as “precision agriculture.” Today, these typically work together toward the surprising result of unvariegated repetition, known commonly as monoculture. After decades of monoculture’s proliferation, its numerous inefficiencies have come under broad recent scrutiny, leading to diverse thinking on ways to redress seemingly conflicting demands such as industry’s reliance on mass-production and automation; the demand for variety or customization in consumer markets; and even regulatory inquiries into the ecological and zoning harms brought by undiversified land use. Monoculture, in short, is proving unsustainable from economic, environmental, and even aesthetic and zoning standpoints. But its handling in digital interfaces, remote sensing and algorithmically directed fabrication is not.

title	Support Form-based Codes with Building Information Modeling – The Parametric Urban Model Case Study
source	ACADIA 10: LIFE in:formation, On Responsive Information and Variations in Architecture [Proceedings of the 30th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-4507-3471-4] New York 21-24 October, 2010), pp. 133-138

summary	This study aims to develop the parametric urban model to support Form-based Codes (FBCs) by using Object-Oriented Parametric Modeling (OOPM) and Building Information Modeling (BIM). FBCs have been used to substitute conventional land-use and zoning regulations in the United States. In many cities, FBCs were implemented successfully, but excessive design constraints, difficult code making process, and missing density of FBCs are criticized. As a response to the increasing needs of parametric modeling approaches in the urban design domain, we applied BIM and OOPM techniques in two case studies. We conclude that BIM and OOPM have a great potential to support planning and design processes, and that the parametric urban model allows FBCs to be more flexible, interpretable, and interoperable.

title	Urban micro-informatics: a test case for high-resolution urban modelling through aggregating public information sources
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 327-336
doi	https://doi.org/10.52842/conf.caadria.2010.327
summary	Our contention is that the city is a rich collection of urban micro-ecologies in continuous formation that include information types outside the traditional boundaries of urban design, city planning, and architecture and their native data fields. This paper discusses working with non-standard urban data types of a highly granular nature, and the analytical possibilities and technical issues associated with their aggregation, through a post professional masters level research studio project run in 2008. Opportunities for novel urban analysis arising from this process are discussed in the context of typical urban planning and analysis systems and locative media practices. This research bought to light specific technical and conceptual issues arising from the combination of processes including sources of data, data collection methods, data formatting, aggregating and visualisation. The range and nature of publicly available information and its value in an urban analysis context is also explored, linking collective information sites such as Pachube, to local environmental analysis and sensor webs. These are discussed in this paper, toward determining the possibilities for novel understandings of the city from a user centric, real-time urban perspective.

title	Diagrams as parametric systems in urban design: parametric systems applied to conceptual design
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 337-346
doi	https://doi.org/10.52842/conf.caadria.2010.337
summary	The paper describes how parametric systems have been used to help students bridge from conceptual design to descriptive results. Specifically, it describes projects set in two cities, Hong Kong and Melbourne, to address substantive urban design issues and illustrate that the approach is not scale or culturally bounded. The project undertaken in Hong Kong establishes interdependency models for dense urban structure and examined urban systems that contribute positively to their contextual setting. Parametric models were used to develop diagrams of site potential through models of air movement, light and sun exposure, in particular addressing air quality in one of the most polluted places in Hong Kong. The Melbourne case studies examine urban systems as self-organising systems. In these, the case studies identify parameters that determine two patterns: material pattern of the city and cognitive pattern of the city. The paper illustrates the use of a parametric system as a diagramming tool to explore urban propositions from an urban system.

summary	Urban design, perhaps even more than architecture, is a timedependent discipline. With its multi-layered complexities, from individual buildings to entire regions, decisions made at one level, that may not show effect immediately, may prove to have disastrous consequences further down the line. The need to incorporate time-based simulations in urban modeling, and the demand for a means of evaluating the changes have led to explorations with multi-agent systems in computation that allow for decisions to be decentralized. From the first basic rule-based system of Conway’s Game of Life [1] to recent urban simulations developed at institutions like the ETH Zurich [2], or UCL CASA [3], these programs synthesize the various exigencies into complex simulations so that the designer may make informed decisions. It is however not enough to simply use parametrics in urban design. Rules or desires implemented at one scale may not apply to another, while isolating each scalar layer for independent study reverts to the disjunctive and shortsighted practices of past planning decisions. Central to current parametric research in urban design is the need to deal with multiple scales of urbanism with specific intelligence that can then feed back into the collective system: a networked parametric environment. This paper will present the results from a city-generator, developed in Processing by Dino Rossi, Dominik Zausinger and Jeannette Kuo, using multiagent systems that operate interactively at various scales.

summary	The main instrument of urban regulation in Brazil is the plano diretor. Currently, apart from serving as a legal document, it is also the sole means of representation of the rates, zones and boundaries that it determines. However, this representation has been inefficient and, given the need to include civil society in decision - making, it becomes imperative that the impact of decisions be reviewed and communicated. As an effort to solve this problem, we propose the creation of an interface that combines information design and GIS (geographic information systems) in the format of an interactive diagram.

title	Parametric Design of the Vela Roof
source	CAAD - Cities - Sustainability [5th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2010 / ISBN 978-1-907349-02-7], Fez (Morocco), 19-21 October 2010, pp. 231-240
summary	Due to the increased request for representative structures and for spaces to be used independent of the weather conditions, contemporary cities increasingly integrate public covered spaces (shadowed squares and streets, courtyards, historic commercial galleries, etc.) in the urban fibre. Facing the design of large roof structures for semi outdoor spaces is increasingly common for architects and engineers. When focusing on large roofs, aesthetics, structural performance and economics often dominate the design process. However, the current increased emphasis on energy-related aspects generates new challenges. Particularly, the use of renewable energy resources needs to be confronted. In this paper we will address the subject through a case study whose design aimed at integrating performance evaluations in the very early stages of the process. The case study focuses on the so-called “Vela roof”. This roof is part of a larger project currently under construction in Bologna (Italy). The focus of the study concerns the use of on-site renewable climate (energy) resources with special attention given passive reduction of summer overheating and daylight. For these tasks a parametric model was developed to support the decision making process and the paper will present its potential with respect to performance-oriented design during the conceptual design phase of roof structure. The very first conceptual design developed by the architectural office was assumed as a starting point for the inclusion of performance criteria. In the preliminary design of the roof uncomfortable conditions were expected under the whole roof in the summer. Various strategies for improving the thermal comfort were investigated, involving a large set of combined systems. Not all of these will be detailed in this paper. Instead we will focus on the ones directly affected by the geometry of the roof. Those are mainly air flow for cooling and the reduction of solar gain, in combination with their effects on daylight. Their investigation was based on a chain of dependencies to be integrated in the design process. With respect to that, parametric modelling was used. Parametric modelling allows both geometrical entities and their relationships to be represented. These relationships are structured in a hierarchical chain of dependencies, established during the preliminary parameterization process. The independent properties of the model are usually expressed through independent parameters, and their variations generate different configurations of the model. By making use of this potential, three project scales were parametrically explored. At the large scale, parametric variations of the overall shape of the roof were investigated in relation to cooling through ventilation and here the parametric model allowed for the generation of both different configurations of the roof, including its structural morphology and variations of its structural tessellation. At the medium scale, the integration of openable modules was investigated in relation to air extraction for cooling; with respect to this, the parametric model allows exploring openings based on variations of size and distribution. At the small scale, various options were explored for the cladding system, in order to reduce the direct solar gain while still allowing the income of indirect natural light. The parametric model was used to investigate the configuration of self-shading modules and their integration in the structure. Specific emphasis will be given to the small scale. The advantages in design process and the current limits of the parametric modelling approach used here will be discussed in the paper.

summary	The paper introduces, analyzes and evaluates the outcomes of a design experiment that took place at the Aristotle University of Thessaloniki in the form of an intensive workshop on parametric urban design. The strategies and methods adopted defined a field for design experimentation as a response to the broader disciplinary discourse related to the use of advanced digital tools, their potentialities in dealing with urban form and their role in architectural education. The workshop’s operative processes and the results obtained serve as a paradigm for an alternative urban design approach. The analysis and the evaluation of this specific approach give rise to further questions and define the goals and anticipations of related future investigations.

summary	Spurring new and innovative building design will be critical to the urban energy and economic future of the nation. The operation of completed buildings account for 48% of the nation’s annual greenhouse gas emissions, and 76% of all electricity generated by U.S. power plants goes to supply the building sector. Therefore developing and applying new and innovative sustainable building design will have a measurable impact on the environment. Recent studies show sustainable building design is closely linked to system integration, where various components of a building work in confluence to produce synergetic benefits. As a result, a critical component of sustainable design involves a clear understanding of building systems operation, interaction, and the selection parameters. A consideration of suitable building systems, gauging their interaction, and proposing well integrated systems can lead to producing efficient models of sustainable buildings with minimal impact on the environment. The following paper outlines the progress on a project entitled “Building Literacy: the Integration of Building Technology and Design in Architectural Education.” The project develops a digital tool for teaching/learning architectural technology from an integrated systems perspective. The project attempts to immerse students in a simulated environment that is based on the real life practice of architecture. The project accomplishes this by harnessing the capabilities of simulation and dynamic modeling programs, as well as the state of art graphic media, to create compelling and rewarding reasons for students’ engagement in the lear ning process. The project involves a multidisciplinary team of faculty from Florida International University, University at Buffalo the State University of New York, and Iowa State University and is funded by the US Department of Education for the period of 2007-2011.

summary	This paper presents recent research for new mechanical systems and façade designs that are able to respond to environmental changes through local interactions, inspired by biological systems. These are based on a model of distributed intelligence founded on insect and animal collectives, from which intelligent behavior emerges through simple local associations. Biological collective systems integrate material form and responsiveness and have the potential to inform new architectural and engineering strategies. The proposed façade system uses integrated sensors and actuators that moderate their local environments through simple interactions with their immediate neighbors. Computational techniques coupled to manufacturing methods and material logics create an integral design framework leading to heterogeneous environmental and structural conditions, producing local responses to environmental stimuli, and ultimately, effective performance of the whole system.

title	Connect Globally \| Make Locally: Cases in Design - Through - Production Collaboration Between the Academy and Industry
source	SIGraDi 2010_Proceedings of the 14th Congress of the Iberoamerican Society of Digital Graphics, pp. Bogotá, Colombia, November 17-19, 2010, pp. 26-29
summary	Collaboration and information exchange are the primary tactics for a globally connected locally produced design - through - production process. With strategic industry partners, Ball State University students test knowledge through real - world applications. While the open access to knowledge in the global environment is critical, it is also imperative to consider the ethic of production and regionally specific conditions under which work is enabled. To this end, the paper will reveal specific design - throughproduction industry - partner collaborations, while exploring the regional implications of making locally, and consider the role of the university to serve as a local catalyst for change in a shifting global economic climate.

summary	Future Cities – the title of the 2010 eCAADe Conference describes one of the major challenges of the 21st century. The conference theme is a logical evolution from previous years in that it expands the focus of interest from the building to larger scales and higher complexity. The conference contributions describe methods and instruments that were developed in the last three decades and apply them to city and territorial planning. The eCAADe proceedings demonstrate that CAAD research and education of the past prepared the ground for the future and for the increased responsibility of the CAAD community. The population of cities has developed worldwide from a minority to the majority. Cities are the largest, most complex and most dynamic man-made systems. As vibrant centres of cultural life and of mega events, they are engines that drive local and global economies. However, their growth was in the fewest cases determined by sustainability goals. As a result, contemporary metropolitan territories are often environmentally, socially and economically unsustainable entities placing increasing pressure on the surrounding rural areas. No longer do traditional methods support the planning and managing of large cities – these methods have reached their limits. Parallel to the revolution in the design of buildings, we need a radical re-thinking of the planning, design, development and management process of cities and urban-rural systems. Compared to buildings, urban and rural systems involve a much higher number of stakeholders and decision makers. We need to study and simulate the effects and side effects of urban-rural planning or re-development much earlier in the process than normally done today. The goal seems clear: the transformation of existing and the planning of new sustainable urban-rural systems. As ordering principles we can build on experiences with building architecture. Complexity, dynamics, scale, and the urban metabolism evolve as promising research and education areas.

title	Parametric Design Process of a Complex Building In Practice Using Programmed Code As Master Model
source	International Journal of Architectural Computing vol. 8 - no. 3, pp. 359-376
summary	Parameter based design explorations inevitably require a unified master model that represents the current design state, where each parameter being explored is essentially a critical sub-case of this master model. Throughout the constantly changing design state, it is beneficial to maintain a master model that is flexible and adaptive. This paper describes the design process of a complex building whose master model documented the design logic through implementation of software code. This process is illustrated by the case study of Lotte Super Tower (Seoul, Korea) from the beginning of schematic design to end of construction document phase. By maintaining the master model as a platform-free software code, in contrast to platform-dependent methods, the case study illuminates the advantages of documenting the generative logic behind design variations in a way that allows greater flexibility and a higher level of alignment with design intent.

title	Automated Cost Analysis of Concept Design BIM Models

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	The recent developments in digital technologies and contemporary design tools are initiating new approaches of form-finding based on parametric development of multiple geometries with simultaneous consideration of various aspects. This paper focuses on the use of advanced parametric CAD systems and reformulated construction logics to enhance the potential and possibilities of form finding processes. This approach is exemplified through the “Greenhouse Trauttmansdorff project”. The project demonstrates a form finding approach which is based on defined parameters that not only fulfil aesthetic and functional aspects, but simultaneously take structural properties and the resulting sun shading behaviour into account. We will explore within this paper how – next to the functional and contextual building requirements – required illumination levels inside the greenhouse create a feedback loop between the structural system and its cladding system.

summary	The research presented in this paper investigates ways of providing better design applications for technologies in the field of Urban Digital Media (UDM). The work takes an emergent approach, evolving a design strategy through the early engagement of stakeholders. The paper discusses research in a design-led creative intersection between media technology, culture and the arts in the built environment. The case study discusses opportunities for the enhancement of a university campus experience, learning culture and community, through the provision of an integrated digital presence within campus architecture and urban spaces. It considers types of information architecture (Manovich, 2001) and designs for use in urban settings to create communication-rich, advanced and interactive designed spaces (Haeusler, 2009). The presented research investigates how to create a strategy for display technologies and networked communications to transform and augment the constructed reality of the built environment, allowing new formats of media activity.

summary	As issues of sustainability gain traction for architects, methodologies for designing, analyzing, and calibrating design solutions have emerged as essential areas of research and development. A number of approaches have been pursued with regard to embedding data into the design process, most fall into one of two approaches to research. The first approach is to mediate environmental impact at the level of applied technology; the second alters building methods and material construction, generating efficient energy use. However, few approaches deal with the crafting of relationships between information and performance on an architectural level. We will examine an approach focused on understanding how crafting relationships between information and design can move architecture towards achieving sustainability. In developing this approach, we created a data-driven design methodology spanning from design inception to construction. Data-driven models, common in the fields of natural science, offer a method to generate and test a multiplicity of responsive solutions. By contextualizing the solutions generated, we were able design though a set of specific and controlled responses rather than as a singular solution. Information utilization requires a new kind of craft that moves beyond instances into relationships and offers performance sensitive issues in design a focused trajectory. We applied this method to the research and development of a responsive shading structure built in conjunction with a thermal testing lab for two test locations – Austin, Texas (Figure. 1 and 2) and Munich, Germany. The following paper chronicles the design and construction at the Texas site over an academic semester.

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 ‚Äúgingerbread houses‚Äù, 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.
