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.

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 project Knitectonics aims at exploring digital fabrication systems that facilitate optimized, adaptive and specific integrated architectural solutions (Male-Alemany 2010). It is inspired by the beauty of nature systems with their inherent efficiency and performance. The research explored on-site fabrication of monocoques shells, integrating skin and structure along with services and infrastructure, using a simple household technique. It thus embodies a self organized micro system of textures and a macro system of structures. This paper elaborates how the numeric aspects of a textile technique were used, first to digitally imitate the process of assembly and further exploited to develop and visualize a novel fabrication system, based on material research and technical experimentation.

summary This paper presents research in response to environmental concerns we face today. In a search for a better method to manage spaces and building resources consumed excessively through traditional top-down architectural solutions, the research began by speculating that the building spaces and resources can be managed by designing architectural systems that encourage a bottom-up approach. In other words, this research investigates how to design systems that encourage occupants and users of buildings to actively understand, manage and customise their own spaces. Specific attention is paid to the participation of building users because no matter how sophisticated the system is, the building will become as wasteful as conventional buildings if users cannot, or do not want to, utilise the system effectively. The research is still in its early stages. The intension of this paper is to provide a background to the issue, discuss researches and projects relevant to, but not necessarily about, architecture, and introduce a number of hypothesis and investigations to realise adaptable, participatory and sustainable environments for users.

title Computational Environments with Multimodal Representations of Architectural Design Knowledge
source International Journal of Architectural Computing vol. 8 - no. 4, p. 439
summary This article discusses interaction between multimodal representations of architectural design knowledge, particularly focusing on relating explicit and implicit types of information. The aim of the presented research is to develop a computational environment that combines several modes of representation, including and integrating different forms of architectural design knowledge. Development of an interactive digital-models library and ontological model of architectural design factors are discussed, which are complementary in nature. In a time when BIM software is seen as embodiment of domain knowledge and the future medium of architectural design, this paper presents an interaction between ontological representation of architectural design knowledge and its embodiment in interactive models, thus focusing on the process of design and design space exploration. In the digital environments that we propose, representation of different formats of knowledge, such as visual, linguistic or numeric, are integrated with relational and procedural information, design rules, and characteristics. Interactive search and query based on contextual constraints, and parametric variation of the model based on the information received from ontology are the underlying drivers for design exploration and development.

summary This paper describes a new methodology of deriving innovative hybrid designs using shape grammars of heterogeneous designs. The method is detailed within three phases of shape grammars: analysis, synthesis and evaluation. In the analysis phase, the research suggests that original rules of each design component are grouped in subclass rule sets to facilitate rule choices. Additionally, adding new hybrid rules to original rules expands the options available to the grammar user. In the synthesis phase, the research adopts state labels and markers to drive the design generation. The former is implemented with a user guide grammar to ensure hybridity in the generated design, while the latter aims to ensure feasible designs. Lastly evaluation criteria are added to measure the degree of innovation of the hybrid designs. This paper describes the derivation of hybrid minaret designs from a corpus of heterogeneous traditional minaret designs.

title Towards Changeability

summary Many buildings around the world have undergone successive changes over their life cycles. Regardless of the type or size of a building there are usually requirements for change due to several unanticipated forces and emerging uncertainties that act upon them. These changes might be in the building’s spatial, structural or service systems. This can be due to changes in the needs of occupants, the market demand or technological advances. Although buildings undergo change, current design practice does not address this and buildings are still designed as if they will remain static. This paper proposes an Adaptable Buildings Design (ABD) Framework to address the issue of adaptability in building design. Using this methodology uncertainties and future changes are first identified. To increase the building’s longevity, flexibility options are embedded and design rules are formulated to trigger these options when necessary. The value of adaptability is then assessed by implementing several simulations using Real Options Analysis (ROA). To demonstrate the approach, the ABD is applied to a multi-use commercial building case study. Flexibility is embedded in the building’s design across several systems allowing it to change and evolve over time based on a set of design rules. The buildings adaptability is then assessed using ROA. Positive results demonstrate the strength of the proposed methodology in addressing future change and uncertaintie.

summary This paper posits a design approach that integrates multi-agent generative algorithms and structural topology optimisation to design intricate, structurally efficient forms. The research proposes a connection between two dichotomous principles: architectural complexity and structural efficiency. Both multi-agent algorithms and Bi-directional evolutionary structural optimisation (BESO) (Huang and Xie 2010), are emerging techniques that have significant potential in the design of form and structure.This research proposes a structural behaviour feedback loop through encoding BESO structural rules within the logic of multi-agent algorithms. This hybridisation of topology optimisation and swarm intelligence, described here as SwarmBESO, is demonstrated through two simple structural models. The paper concludes by speculating on the potential of this approach for the design of intricate, complex structures and their potential realisation through additive manufacturing.

summary The present paper describes the design process of a new prototypical building for the State University of Campinas, with the use of shape schemata and rules. The use of this construct or method made the design process more intelligible for the students who took part in the project and helped managing the team work. We expect that these rules will also allow the automation of the production of design alternatives and construction drawings for new buildings in the campus.

summary Algorithm Aided Architectural Design (AAAD) is considered a second paradigm shift in the Architectural design process after the first one of bridging the conventional design process to the digital realm of design. This paper is divided into two parts, the first part comprehends the Algorithmic Architecture approach of from the point of view of tools, techniques, theories and practice in order to find the Algotecture theories on the map of Digital Architecture. Then, the paper exemplifies an application on Algorithmic Architecture. FALLINGWATER TOOLBOX VERSION 1.0 is a computational design demo tool for architects to aid in the house schematic design phase according to an analytical study of Frank Lloyd Wright's basic design rules and spatial program of his masterpiece; FallingWater House, (Edgar J. Kaufmann family house 1939). These rules have been transferred to algorithms and code thereafter. At a preceding stage, the Graphical User Interface (GUI) was developed using MAXScript 9.0. Using the FALLINGWATER TOOLBOX, infinite number of house prototypes can be generated within few minutes. Although, the FWT is based on a hypothetical design problem of producing prototype alternatives for a new house with the same identity of the Edgar Kaufmann House, the concept of the tool can be applied on a wider range of problems. It may help generating prototype alternative solutions for residential compounds design according to the required constraints.

title Quantum architecture: an indeterministic and interactive computational design system

summary The evolution of computational design technique from mere substitution of hand drawing to customised design algorithms exhibiting a certain degree of intelligence, naturally opens up a new research frontier that studies the relationship between designers and customized design algorithms. Most of current customised architecture design algorithm adopts a deterministic paradigm to raise their design questions, that is to say, given the explicit rules and parameters, only one solution is allowed at each discrete computation step. Due to this deterministic nature, an intuitive and efficient communication between design algorithm and designer is hard to achieve, as there is almost no space for designer to step into the running generative process. This lack of progressive communication channels and the inefficiency of translating perceptual judgment into computer language directly results in the unconscious rejection of non-parameterisable design factors like intuition, aesthetic judgment and associational reasoning that are essential to any design activity. This paper introduces the quantum design paradigm as alternative computation paradigm for constructing an interactive and intuitive design system. An algorithm prototype, probability field, will be introduced to illustrate the logic and possible application of the proposed quantum design paradigm.

summary This program converts bubble diagram into an agent-based system for architectural design. The program suggests a model for layout planning based on bubble diagram which explicitly describes the adjacency requirements in architecture. Generally there is a basic set of rules for every agent dealing with adjacency topology and also an alternative set for other objectives. Then this basic program is developed into several generative tools for different design tasks. They imply that the agent-based system is efficient for elementary spatial arrangement and it could generate a wide range of complex solutions.

summary Graphic designers always take both time and efforts when they are creating a decorative pattern with complicated curves and a great deal of motifs. Although there are many sourcebooks of decorative patterns, the satisfaction of the results couldn’t accomplish with designer’s requirements. Thus, graphic designers need a faster and easier system to create decorative patterns in classical style. There are a few effiencient methods to analysis curves and surfaces in the development of shape grammars. The purpose of this research is to develop Vine Grammar based on shape grammars. The vine grammar analyses principles hidden in the language of deisgn works to create the order, then generates design by using Bézier curves. This research also presents the development of a decorative pattern generative system called Shlishi by using FLASH Action Script 2.0. The grammar can be applied with computers and to verify rules quickly by Shlishi. The intention of this research is to make graphic designers to use these rules to create decorative patterns of plants in classic style and to produce satisfactory results for designer more efficiently or to make the results the source materials for the follow-up design works.

summary Architects and designers have often used computational design techniques in their design process, even without "computers", from designing spaces which activate at the instant of the solstice sunrise, to creating geometrically complex and structurally innovative cathedrals. Designing with rules and variables can lead to solutions which satisfy the design criteria and may result in interesting and unanticipated models. Computational design is a process of designing and a way of thinking; contemporary tools can promote and enhance this process. Algorithmic and parametric modeling (and thinking) can be powerful processes in design, and particularly in working with complex geometry and addressing project constraints and analytical and data-driven design. This paper describes these methods and provides examples of their use on projects at Skidmore, Owings & Merrill.

summary This paper demonstrates an ongoing research investigation, which is the continuation of the author’s doctoral research on a computer-based design approach that is used for the generation of circulation diagrams, and the spatial organization of functional areas in macro-scale design level. The paper introduces a computer program that is based on the idea of particle behavior modeling. The program simulates the human movement behavior in real time and in parallel, based on simple rules of interaction between particles. The model is called a ‘virtual force’ model, since the interaction between particles, and hence human movement behavior modeling, is achieved by using various forces that are acting upon each particle. Any changes on the rules of interaction can produce different results, allowing architects to investigate various design possibilities and study the human movement behavior in different design case studies. In this paper the idea of modeling such movement behavior is investigated and developed further, in order for it to be used for the design of circulation systems, and to suggest solutions to problems that occur in public areas of cities.

summary This paper details the process that students of UAE University’s Department of Architectural Engineering have undergone in packaging architectural heritage data online. Facilitated by the Abu Dhabi Authority for Cultural Heritage, students were introduced to historical data. They digitally reconstructed a historical fort in Al Ain, UAE – Al Jahili Fort – and investigated methods of packaging the gathered information online. Some observations and assessments (strengths and weaknesses) pertaining to the unique historical information packaging are highlighted in this paper. In addition to acquiring skills in producing architectural abstractions and graphic composition, students assessed several online interactive techniques. A set of rules or patterns were prescribed to enhance the clarity of chosen data. While providing insights to the processes of and considerations in designing an online information package for an architectural heritage project, the underlying objective is to question the possibilities and role necessary in sculpting the future of CAAD education to propel the discipline forward through the medium. What would be the implications? It also asserts the notion that digital space may be architectural education’s imminent next ‘final’ frontier.

summary This paper develops a formal approach to investigate the evolution of a Korean traditional pattern, Bosangwhamun. The approach employs the structure of symbolic memes embedded in the pattern as a framework of hierarchical decomposition of a pattern to describe an evolutionary development process of a given pattern with a set of rules in shape grammar as style changes. Further, the formal descriptions of the given pattern become the basis for generating its variations. With this process, the validity of the rules and their appropriateness in the representation of Bosangwhamun are examined.

Friedman was a conceptual creator of mega - structures that were multiplied in several layers of cities in which users were responsible for choosing designs while being informed of the consequences. They used a computer containing the design options and described their way of life, which was translated into the use of environments. According to the spaces chosen from this list, the user could reconfigure the space. Although, considering that the city was an environment, the space could be selected while watching a computer simulation. Users’ choices depended on absolutely parameterized rules.

title On Connecting Panels of Freeform Building Envelopes

summary As smooth geometric shapes are very tricky to manufacture with an overall great expense this paper presents a parametrical approach how to control the joint geometry within a framework of flat panels which approximate a freeform surface using discretization. Since timber has an excellent reputation as a sustainable and regenerative material plus the fact that timber can be perfectly processed with a large variety of tools including CNC milling machines we are using cross laminated timber boards (CLT) with large and heavy members. Hence that means dealing with high forces which require geometrically exact and often complex joints, which we want to push to a high degree of automation in the design process. We establish rules and constraints between all neighboring CLT-panels. That way we control a new connector system specially designed for non-standard CLT-joints. This paper documents the status of one aspect of an ongoing research project and will also give a preview to upcoming tasks including the production of a prototype structure.

summary The design of laboratory buildings entails the implementation of a variety of design constraints such as building codes; design guidelines and technical requirements. The application of these requires from designers the derivation of data not explicitly available at early stages of design, at the same time there is no precise methodology to control the consistency, and accuracy of their application. Many of these constraints deal with providing secure environmental conditions for the activities inside laboratories and their repercussions both for the building occupants and population in general, these constraints mandate a strict control over the building’s Mechanical Equipment (MEP), in particular the Heating Ventilating and Air Conditioning (HVAC) system. Due to the importance of these laboratory designers are expected to assess their designs not only according spatial relationships, but also design variables such as HVAC efficiency, air pressure hierarchies, operational costs, and the possible implications of their design decisions in the biological safety of the facility. At this point in time, there are no practical methods for making these assessments, without having constant interaction with HVAC specialists. The assessment of laboratory design variables, particularly those technical in nature, such as dimensioning of ducts or energy consumption are usually performed at late stages of design. They are performed by domain experts using data manually extracted from design information, with the addition of domain specific knowledge, the evaluation is done mostly through manual calculations or building simulations. In traditional practices most expert evaluations are performed once the architectural design have been completed, the turn around of the evaluation might take hours or days depending on the methods used by the engineer, therefore reducing the possibility for design alternatives evaluation. The results of these evaluations will give clues about sizing of the HVAC equipment, and might generate the need for design reformulations, causing higher development costs and time delays. Several efforts in the development of computational tools for automated design evaluation such as wheel chair accessibility (Han, Law, Latombe, Kunz, 2002) security and circulation (Eastman, 2009), and construction codes (ww.Corenet.gov.sg) have demonstrated the capabilities of rule or parameter based building assessment; several computer applications capable of supporting HVAC engineers in system designing for late concept or design development exist, but little has been done to assess the capabilities of computer applications to support laboratory design during architectural Preliminary Concept Design(PCD) (Trcka, Hensen, 2010). Developments in CAD technologies such as Building Information Modeling (BIM) have opened doors to formal explorations in generative design using rule based or parametric modeling [7]. BIM represents buildings as a collection of objects with their own geometry, attributes, and relations. BIM also allows for the definition of objects parametrically including their relation to other model objects. BIM has enabled the development of automated rule based building evaluation (Eastman, 2009). Most of contemporary BIM applications contemplate in their default user interfaces access to design constraints and object attribute manipulations. Some even allow for the application of rules over these. Such capabilities make BIM viable platforms for automation of design data derivation and for the implementation of generative based design assessment. In this paper we analyze the possibilities provided by contemporary BIM for implementing generative based design assessment in laboratory buildings. In this schema, domain specific knowledge is embedded in to the BIM system as to make explicit design metrics that can help designers and engineers to assess the performance of design alternatives. The implementation of generative design assessments during PCD can help designers and engineers to identify design issues early in the process, reducing the number of revisions and reconfigurations in later stages of design. And generally improving design performance.
