title	Design by Algorithms: A Generative design system for Modular Housing Arrangement
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	This paper explores the applicability of algorithmic design in a real-world architectural context; through the creation of a generative system for modular housing arrangements (MHAS). It is a user interface in Autodesk Maya based on stochastic search to produce various alternatives for the modular housing arrangements. Through the UI, the designer can enter parameters and rules, and then the MHAS will produce 3D alternatives according to the specified frame conditions and renders a selected view. This generative system is expected to facilitate the design process, generate unexpected solutions for well specified rules, and save time consumption in the early design process.

title	The Use of the Smart Geometry through Various Design Processes: Using the programming platform (parametric features) and generative components
source	Digitizing Architecture: Formalization and Content [4th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2009) / ISBN 978-99901-06-77-0], Manama (Kingdom of Bahrain), 11-12 May 2009, pp. 297-304
summary	The emergence of parametric generative design tools and prototyping manufacturing technology led to radical changes in architectural morphologies. This change increased the opportunity to develop innovative smart geometries. Integrating these algorithms in the parametric softwares led to variations in building design concepts increasing alternatives and decreasing the repetitive work previously needed in conventional CAD software. The chosen software in this research is Generative Components (GC). It is a software design tool for an associative and parametric design platform. It is tested for using Global Variables with associative functions during the concept creation and form GC comprises features. The results presented in this research may be considered an introduction to the smart geometry revolution. It deals with the generative design which applied in the design process from conceptual design phase, defining the problem, exploring design solutions, then how to develop the design phases. Office building is a building type which encourages new forms that needs computational processes to deal with repetitive functions and modular spaces and enclosed in a flexible creative structural skin. Generative design helps the office buildings to be arranged, analysed, and optimized using parameters in early stages in design process. By the end of the research, the use of the smart geometry in a high rise office building is defined and explained. The research is divided into three parts, first a summary of the basic theories of office buildings design and the sustainable requirements that affect it, and should be integrated. Secondly, the previous experiences in generating office buildings by Norman foster and Sergio Araya. At last, a case study is proposed to test and evaluate the use of the parametric generative methodology in designing an office building with specific emphasis on the function, environmental aspects and form generation using Generative Components (GC) Software.

title	Systems-Thinking: Formalization of parametric process
source	Digitizing Architecture: Formalization and Content [4th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2009) / ISBN 978-99901-06-77-0], Manama (Kingdom of Bahrain), 11-12 May 2009, pp. 215-223
summary	This paper details a design process focused on explicit digital parametric modeling as an integral system-outcome design. This investigation isolates and alters a simple geometric form (cylinder) in a constructed architectural design method. Systems are defined as logical, sequential operations inherent to the resultant effects. These operations within each system are composed of various parameters, singular entities containing or referencing data. Given specific data, operations are preformed culminating with corresponding outcomes. The two main components of this research pertain to object extraction and transformation. A single grain silo (cylinder), as the architectural/geometric object under examination, is tested using a system of varied parameters inputted into the program Grasshopper, an “explicit history” graphic plug-in for Rhinoceros. This application is utilized to digitally manipulate parameters as objects in a nodal arrangement. Throughout the operations execution, this isolated silo will be transformed into a multitude of versions, then regrouped into the original cluster of silos to expose the implications from patterning, adjacency, and repetition given the proximity of the each silo and its new parametric characteristics. As the various parameters in specific operations affect the system as a whole, so is each adjacent silo in proximity given the same or similar operation? This then is translated and reflected in the outcome. This research seeks to explore design process by applying constant digital 3-D reductive geometric, modular forms inviting systems thinking in parametric environments that can lead to architectural design implications. By focusing on the technical aspect of the parameterization and valuing functionality rather then style, the process becomes focused on formal qualities as the system-outcome relationships. This research tests the “aesthetic implications” of a varied mode of digital design, namely the investigation of an architectural process utilizing parametric design.

title	Physics-based generative design
source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 231-244
summary	We present a physics-based generative design approach to interactive form-finding. While form as a product of dynamic simulation has been explored previously, individual projects have been developed as singleton solutions. By identifying categories of computational characteristics, we present a novel unified model that generalizes existing simulations through a constraint-based approach. The potential of interactive form finding simulation is explored through exemplary studies: a conceptual approach to a fixed form that acts as a visualization of interacting forces, and a constraint-based model of the fabrication logic for a panelization system are examined. Implications of constraint-based simulation on future directions are discussed.

summary	The paper investigates knotting techniques as a method for generating wall systems. The essential matter of the paper is to demonstrate the potential of knotted, algorithmic architecture through different research studies, which share the knotting of linear elements as a common methodology for design development. Combinatorial Productivity implies that by combining linear elements hidden properties of a system emerge and thereby the system becomes productive.

source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The street system is an important component of the city ontology created for a generative urban design tool and should be able to integrate the many visions or interpretations that designers or other urban design agents may have about streets. This paper describes several characteristics of the street system, with its components organized into object classes which are the shape sets of algebras used by a generation module to generate street network representations that can be assessed by a GIS platform.

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.

summary	The goal of this research is to define a methodology for the construction of complex non-repeating surfaces and structures that rely on the formulation of a singular tectonic mechanism. Computational systems like cellular automata seem to suggest that it might be possible for modular material systems to self-assemble into complex organizations. A single series of modular parts could be capable of producing not only complex behavior, but also, depending on initial conditions, simple periodic behavior. The research outlined in this paper uses simple geometric transformations to produce tectonic computers that can be applied to a variety of building systems. This paper outlines a methodology for encoding and decoding material assemblages as discrete computational systems. Exploiting the combinatorial nature of tectonic systems makes it possible to produce a population of “material algorithms” capable of exhibiting a wide range of behaviors. Encoding assemblages as discrete systems affords the designer the ability to enumerate and search all possible permutations of a tectonic system. In this paper, we will discuss the calculations and computational processes used to encode material assemblages as populations of discrete algorithms.

title	Generative systems in the architecture, engineering and construction industry: A systematic review and analysis
source	International Journal of Architectural Computing 2021, Vol. 19 - no. 3, 226–249
summary	Researchers have been extensively exploring the employment of generative systems to support design practices in the architecture, engineering and construction industry since the 1970s. More than half a century passed since the first architecture, engineering and construction industry’s generative systems were developed; researchers have achieved remarkable leaps backed by advances in computing power and algorithms’ capacity. In this article, we present a systematic analysis of the literature published between 2009 and 2019 on the utilization of generative systems in the design practices of the architecture, engineering and construction industry. The present research studies present trends, collaborations and applications of generative systems in the architecture, engineering and construction industry in order to identify existing shortcomings and potential advancements that balance the need for theory development and practical application. It provides insightful observations that are translated into meaningful recommendations for future research necessary to progress the incorporation of generative systems into the design practices of the architecture, engineering and construction industry.

doi	https://doi.org/10.52842/conf.caadria.2009.013
summary	This paper examines a different design approach called integrated. The term “integrated” has a dual utilization in this study. The first use refers to the integration of form and building performance. The second use refers to the integration of interrelated and diverse building performances involving multiple disciplines. The integrated design approach analyzes and evaluates several interrelated design systems involving different disciplines in the early design phase. The goal of the approach is the generation of design alternatives guided simultaneously by two basic objectives: the aspiration for form exploration and the satisfaction of the performances of interrelated systems.

doi	https://doi.org/10.52842/conf.caadria.2009.381
summary	This research examines the value of “redesigning the brick,” in creating a new vocabulary of basic architectural building blocks with autonomous reconfigurable robotics. The paper highlights several built examples by the author of robotic architectural environments and the work of architecture students whereby individual modules were created within the context of a design studio and applied to scenarios of space making at various scales. Several strategies for decentralized control were explored dictating how individual parts of a system should behave and how local interactions between individual modules can lead to the emergence of global behaviour. The students schematically designed selfreplicating models which would allow for each object to be able to attach, detach, and reconfigure according to predetermined computational logic. The projects successfully demonstrate various strategies for mechanical design, locomotion and control.

summary	This study is about building a conceptual architecture called Meta-form that can perform the acts of parametric design to generate various house forms. The study limits its scope to four genotypes of residential houses in the world. Typological Analysis is employed as a technique of distinguishing the key variables shared by the built forms. The result, with respect to each genotype, there are specific meta-form systems account for the generation of cases of phenotype by assigning different values to each corresponding parameter. With its generative power the meta-form system is evidently a useful tool to assist type-based form productions. As such, the parametric values also acquired the descriptive power of specifying built form characters.

summary	Reinforced concrete has been one of the essential materials for modern architecture for the last hundred years. Its use is entirely global, having been adopted by all cultures and styles since its invention in the late 19th century. Although its value is excellent due to its low cost, durability and adaptability, its environmental impact is significant, being, in fact, one of the most polluting industries in the world (Babor et al. 2009). This experimental project will research a more sustainable use of concrete, exploring a new form of reusable concrete formwork that will ideally reduce the CO2 footprint by removing wood waste in the casting process and replacing it with adaptable metal components. The modular part-based system for the concrete casting also attempts to simplify one of the current complexities for concrete construction, the Skilled-Labour shortage. (Yusoff et al. 2021). To mitigate this problem, the project also proposes using an Augmented Assembly logic for the casting parts to guide the ensemble and dismantle the formwork through an optimised algorithmic logic. The use of Augmented Reality as a replacement for traditional paper instructions will facilitate access to more workers to this construction art and potentially improve access to optimised use of concrete in developing communities with restricted building technological resources.

summary	This paper presents an evolutionary algorithm that draws its power from the literal interpretation of the natural system’s reproductive process at a microscopic scale with the scope of generating optimal Delaunay triangulated space frames for dynamic loads. The algorithm repositions a firm number of nodes within a space envelope, by establishing Delaunay tetrahedra and, consequently, creating adaptable optimised space frame topologies. The arbitrarily generated tetrahedralised structure is compared against a canonical designed one and the results of this comparison indicate that the method proposed has advantageous properties and is capable of generating an optimum structure that exceeds statically the performance of an engineered tetrahedralised space frame.

title	Generating a scalar logic: producing the "it's a SMALL world" exhibition
source	International Journal of Architectural Computing vol. 9 - no. 2, 115-132
summary	This paper presents the design project “it’s a SMALL world”, an exhibition design developed for the Danish Design Centre in 2009.The project investigates the making of a generative design environment by which multiple design parameters as from program, site or the subsequent digital fabrication and assembly process can be negotiated. In this paper we discuss methods for understanding the emergent interrelationships between encoded parameters, how to manage these and their impact on design.The implementation of the design necessitated a novel design method that allowed to blend the qualities of a generative design approach, that can adapt through recursion gradually to local requirements, with explicit definitions.The project showcases with its new developed manufacturing system for non- standard element how customized digital design and production tools allow for a novel nearness to material and new ways of production and collaboration of architects, engineers and the crafts.

title	Beyond Traditional CAAD: E-Learning supporting design thinking
source	Digitizing Architecture: Formalization and Content [4th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2009) / ISBN 978-99901-06-77-0], Manama (Kingdom of Bahrain), 11-12 May 2009, pp. 71-87
summary	A study based on a post-occupancy-evaluation (POE), conducted in housing developments in the region of Campinas, Brazil, evaluated quality of life and sustainability indicators. These indicators were then related to site planning design guideline for low-income public housing projects that considered recommendations for integrated community and security, street and path system and parking, public and private open space and landscaping. Since this work is part of a broader study, which aims to develop evaluation tools, the proposed design guidelines were used by students in a graduate class, in order to verify its effectiveness. Bloom’s Taxonomy was used to determine educational goals for design thinking in this class. First design thinking was instigated based on students’ prior knowledge of life quality and sustainability indicators for housing design. Comprehension of proposed design guidelines was stimulated by the reading and discussion of related literature, paraphrasing or extension of proposed design guidelines and respective illustration with reference images. An existing low-income housing development, with award winning design, was selected and an evaluation of its conformance to proposed design guidelines was conducted comparing site or design images to reference images. This evaluation subsidized a design exercise for the selected housing development. The class was offered as a partially distance course with an agenda including: tutorials, theoretical classes, seminars and conceptual discussions. A new Brazilian open source e-learning environment was experimented and critiqued. Beyond traditional CAAD tools others such as wiki, blog, polls, chat, conferencing, web authoring and visit broadcasting supported collaborative learning and design. Results indicate the viability of design teaching in distance education courses for competent designers; however the experience shows the need for innovation in synchronous communication and visualization tools specific for architectural design users. Students evaluation of selected housing development and final projects indicate that the proposed guidelines for low-income public housing projects successfully supports the decision making process in order to incorporate quality of life and sustainability indicators in design. The experience presents a model of design education which incorporates technology integrated to human and environmental dimensions.

title	Preliminary Concept Design (PCD) Tools for Laboratory Buildings, Automated Design Optimization and Assessment Embedded in Building Information Modeling (BIM) Tools.
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. 451-476.
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‚Äôs 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.

title	The Consideration of Lifelong Owner’s and Property’s Characteristics in Nd Cad System: The case of affordable housing in kingdom of Saudi Arabia

summary	Residential property value is affected by several factors during its useful time. . These factors include people’s lifestyles, traditions and culture, and the way they live and interact with the built environment. The property characteristics such as its location, building quality, adaptability, and energy efficiency would also have an impact on the property value. On the other hand, the nD CAD research that emerged in the late 1990s proposed endless dimensions of CAD modelling that would incorporate the building regulations’ requirements, basic user needs and client requirements. However, there is a need to implement lifelong parameters that would have significant effect on the property value in 3D models during the early stages of design. This can be done through a knowledge base integrated into a 3D model and links the lifelong property’s and the user’s characteristics with the property’s value. A survey was carried out on banks and Real Estate Development Fund (REDF) in the Kingdom of Saudi Arabia to find out the level of impact of lifelong users and property characteristics on the property’s value. The results of the survey showed a number of lifelong property and user driven parameters that may have major impact on the property’s value. The implementation of lifelong parameters in nD CAD models would have a number of benefits. It would provide the decision makers such as banks and investors with a tool to assess the level of impact of possible lifelong factors on the property value and consider alternative schemes. Designers would use it during the early stages of design to produce optimum design solutions that provide an adequate product that is evaluated regarding its lifelong value to the end users. Eventually it would provide a comfortable environment that is tailored to the user’s needs and aspirations, while reserving the property’s lifelong value.

title	From texture to volume: an investigation in quasi-crystalline systems
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The relation between texture, pattern and massing is a fundamental question in architecture. Classical architecture, as Leon Battista Alberti states in “De re aedificatoria” (Book VI, Chapter 2), is developed through massing and structure first; texture is added afterwards to give the bold massing and structure beauty. Only the ornamentation adds pulcritudo to the raw structure and massing. Rather than starting with a volume and applying texture afterwards, the Digital Girih project started with textural operations that informed the overall volume later. The stereometric, top-down methodology is questioned through the bottom-up methodology of the Girih project. Girih lines of traditional Islamic patterns were used as a starting point. The aspect of 3-dimensionality was developed analogue as well as digital, using the deformability of different materials at various scales and digital construction techniques as parameters. The flexibility within the Girih rules allowed the system to adapt to different tasks and situations and to react to different conditions between 2- and 3- dimensionality. The project in that way explored a bottom-up process of form generation. This paper will describe the process of the project and explain the necessity of digital tools, such as Grasshopper and Rhino, and fabrication tools, such as laser cutter and CNC fabrication technology, that were essential for this process.
