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.

summary	The research presents the importance of the experimentations within education of architecture project. Since the studies for traditional and emergent ways with use them digital tools, it values the project inquiries in the simulations of the models in 3D. For many times, the digital model for being tangible cannot present a difficulty in the understanding of constructive details. As in the digital tools, more specifically BIM (Building Information Modeling) possess integrated standards complex. The necessity of the materialization becomes inevitable use of the Rapid Prototype (RP) that it is a technology that allows the materialization of the complex digital models facilitating to the tactile and percipient use for better understanding and taking of decision.

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 overall economical benefits of Building Information Modeling are generally comprehensible, but are there other problems with the implementation of BIM as a formulized system in a field that ultimately is dependent on a creative input? Is optimization and economic benefit really contributing with an architectural quality? In Denmark the implementation of the digital working methods related to BIM has been introduced by government law in 2007. Will the important role of the architect as designer change in accordance with these new methods, and does the idea of one big integrated model represent a paradox in relation to designing? The BIM mindset requires changes on many levels.

title	Creation of an Evolutive Conceptual Know-how Framework for Integrative Building Design
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 435-450.
summary	Low productivity of the building sector today is attributed to the fragmentation of tasks, disciplines and responsibilities, as well as to the resistance to adopt integrative work processes and digital means. The increased complexity of architectural projects and the aroused social consciousness for sustainable environment calls for integrative design collaboration. Thus, there is need for a Conceptual Framework combining work processes, technological means and policy aspects. According to the literature, integrative multidisciplinary design is a strategy resulting in high performance buildings nurturing sustainable way of living (Reed et al. 2009, Krygiel & Nies 2008). Responding to the increased technological complexity of our built environment, as well as to the objective of meeting multiple criteria of quality, both necessitating multidisciplinary collaboration during design, Building Information Modeling (BIM) is seen as a powerful means for fostering quality, augmenting productivity and decreasing loss in construction. Based on recent research, we can propose that a sustainable building can be designed through an integrative design process (IDP) which is best supported by BIM. However, our ongoing research program and consultations with advanced practitioners underscore a number of limitations. For example, a large portion of the interviewed professionals and construction stakeholders do not necessarily see a link between sustainable building, integrative design process and BIM, while in our opinion, their joint use augments the power of each of these approaches taken separately. Thus, there is an urgent necessity for the definition of an IDP-BIM framework, which could guide the building industry to sustainable results and better productivity. This paper defines such a framework, whose theoretical background lays on studies in social learning (activity theory and situated action theories). These theories suggest that learning and knowledge generation occurs mainly within a social process defined as an activity. This corresponds to the context in which the IDP-BIM framework will be used, its final objective being the transformation of building design practices. The proposed IDP-BIM framework is based on previous research and developments. Thus, firstly, IDP process was well formalized in the Roadmap for the Integrated Design Process‚ (Reed et al.) which is widely used as a guideline for collaborative integrative design by innovating practices in USA and Canada. Secondly, the National Building Information Modeling Standard (NBIMS) of the USA is putting an enormous effort in creating a BIM standard, Succar (2008) recently proposed a conceptual framework for BIM, but BIM ontology is still under development (Gursel et al 2009). Thirdly, an iterative design process bound to gating reviews (inspired from software development processes) was found to be successful in the context of multidisciplinary design studios (reported in our previous papers). The feedback from this study allowed for modifications and adjustments included in the present proposal. The gating process assures the good quality of the project and its compliance to the client's requirements. The challenge of this research is to map the above mentioned approaches, processes and technologies into the design process, thus creating an integrated framework supporting and nurturing sustainable design. The IDP-BIM framework can be represented by a multidimensional matrix linked to a semantic network knowledge database: - the axes of the matrix being the project timeline, the design process actors and building stakeholders (architect, engineers, client, contractor, environmental biologist, etc.), or different aspects of building performance (environmental, functional, social, interior environment quality, cost, etc.); and - the knowledge database providing multiple layers of semantic support in terms of process, domain knowledge, technology and workflow at a given moment of the project and for a given actor or building aspect. The IDP-BIM framework is created as an evolutive digital environment for know-how and will have an established protocol for regular updates. The paper will firstly present the state of the art in IDP and BIM. Secondly, it will expose the methodology used for the definition of the Framework, followed by a description of its structure, contents and digital implementation. Then, some scenarios for the use of the Framework will be shown as validation.

summary	This paper describes the successful development of a design supporting method called ‘Ubicomp-Kaizen’ for the design of computerintegrated ‘smart’ buildings. The tool uses known methods of qualitymanagement of the car-manufacturing industry and integrates them into the architectural design process. By this, the CAAD-topics ‘design methodology’, ‘ubicomp/smart buildings’, ‘interactive architecture’ and ‘Building Information Model (BIM)’ are involved. In result it proves the successful integration and application of tools known from the product development industry such as ‘Quality-Function-Deployment (QFD)’ and ‘Failure Mode and Effects Analyze (FMEA)’ within the iterative building design. The outlook formulates a side-result which is the setup of a digital decision supporting tool and the extension of the IFC-definitions in order to integrate aspects of user-interaction and ubicomp."

summary	Daylighting is an important part of designing sustainably. Daylighting is the use of natural light for primary interior illumination. This reduces our need for artificial light within the space, thus reducing internal heat gain and energy use. Direct sunlight, once it enters the building, is not only light but heat, and that additional heat will need to be taken into account in your energy analysis." While Autodesk Revit Architecture 2010 (ARA) itself cannot perform the actual analysis, there are some ways to do that. This papper focuses on the study of parametric modeling using a BIM tool for daylighting analysis. This paper presents the first part of the building method of LUME, a plug-in maked whit C# programming language in Microsoft Visual Studio 2010 and ARA Software Developer Kit (SDK) package. The script accepts as its input a standard three dimensional model of building opening and his position on space.

title	Depth Perception in Real and Pictorial Spaces: A Computational Framework to Represent and Simulate Built Environments
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 543-552
doi	https://doi.org/10.52842/conf.caadria.2009.543
summary	Architectural design is often mediated on two-dimensional representation systems and envisioned three-dimensionally in the pictorial space. The developments of advanced digital technologies have enabled us to create the pictorial representations of un-built design projects that can appear as real as photographs. The visually appealing pictures produced by photorealistic rendering tools are useful for visualizing the form and the spatial layout of the proposed architectural design; but they may be inadequate and misleading for simulating the perceptual qualities of space. This paper draws from the recent developments in computer graphics (physically based renderings and perceptually based tone mapping techniques) and proposes a computational framework to faithfully represent and simulate pictorial spaces. Guidelines are provided for generating images with appropriate representation and simulation techniques so that architects can make informed design decisions about the perceptual qualities of their designs and researchers can study depth perception in computer environments.

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	Monitoring urban design through generative design support tools: a generative grammar for Praia
source	Proceedings of 15 Congresso da APDR, Cidade da Praia, Cabo Verde.
summary	Abstract Urban planning and design has a considerable impact on the economic performance of cities and regions. It is a complex process that extends for a long period and involves many participants. The lack of integrated tools to support this process hampers the ability to maximize the response of plans to contextual conditions while using the least resources. This paper describes research that aims to develop such a tool, integrating formulation, generation, and evaluation capabilities. It is focused on the generation module which relies on the encoding of Urban Induction Patterns (UIP) using shape grammars. A grammar for the extension plan of the city of Praia is presented as one of the case studies used to support UIP definition and illustrate its application. The paper also discusses how the proposed tool can be used for developing and monitoring urban plans.

summary	We examine an open source 3d suite of tools called blender, as a tool for architectural design. The unique features of blender are examined in terms of ease of use and integrated nature since blender incorporates a simulation engine and a game engine that can be used creatively in the design process. The unique data structure of Blender is examined with the features and work flow that this structure brings in the design process. Also a simple comparison is made between Blender and 3ds max in terms of features and workflow as visualization tools together with an assessment of a two year seminar that took place in the Department of Architecture, in Volos Greece.

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.

summary	The paper outlines the relevance of computational geometry within the design and production process of architecture. Based on the case study “Twister”, the digital chain - from the initial form-finding to the final realization of spatial concepts - is discussed in relation to geometric principles. The association with the fascinating complexity, which can be found in nature and its underlying geometry was the starting point for the project presented in the paper. The translation of geometric principles into a three-dimensional digital design model was followed by a process of transformation and optimization of the initial shape, that integrated aesthetic, spatial and structural qualities as well as aspects of material properties and conditions of production.

summary	A multi-agent system (MAS) is efficient as it can emulate a variety of organisms in natural science due to the interactions between agents, which make artificial systems responsive and adaptive. In “Bamboo Workshop” involved flexible structures, MAS was employed to create virtual organism in computational environment towards an innovative process in installation design. A generative tool with friendly user interface was developed for both observation and intervention besides debugging. At the same time investigations were carried on the complex behaviours of the system through graphic statistics. Integrated with the generative tool, a construction system made up of bamboo materials was set up to build a series of mobile and flexible installations. This experiment suggests that the virtual organism has the potential for being a part of the design intelligence, beyond a mere digital tool.

summary	We present a student design class, in which experimental full-scale parametric objects are planned and built. The class explores the possibilities of digital production chains in which CAAM techniques driven by parametric modeling can expand the range of possibilities for designing and producing architecture. We show how those possibilities and techniques can be integrated into architectural education in facilitating a transition from digital design to actual object. The didactic challenge represents teaching a methodological approach towards parameter-based design, its transfer into a software program and the choice of construction and production method.

title	Programming framework for architectural design ANAR+: Object oriented geometry
source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 771- 785
summary	From the recent advent of scripting tools integrated into commercial CAAD software and everyday design practice, the use of programming applied to an architectural design process becomes a necessary field of study. The presented research explores the use of programming as explorative and reflexive medium (Schön, 1983) through the development of a programming framework for architectural design. Based on Java, the ANAR+ library is a parametric geometry environment meant to be used as programming interface by designers. Form exploration strategies based on parametric variations depend on the internal logic description, a key role for form generation. In most commercial CAD software, geometric data structures are often predefined objects, thus constraining the form exploration, whereas digital architectural research and teaching are in need for an encompassing tool able to step beyond new software products limitations.

title	Concept design tool requirements: Developing a Framework for Concept Design Tool Specifications
source	T. Tidafi and T. Dorta (eds) Joining Languages Cultures and Visions: CAADFutures 2009 CD-Rom
summary	Early design phases generate high project value with relatively little effort. However, digital tools supporting integrated concept design at a high knowledge level are scarce. Research has focused on specific aspects of design tools yielding focused and disjoint insights. An actionable requirements framework will allow assembly of research results into a meaningful, comprehensive concept design tool set and will reveal gaps which will help identify further research opportunities.

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
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. 191-204
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.

summary	Using several NBBJ civic projects as case studies, this paper provides an overview of how NBBJ’s Los Angeles design studio is leveraging parametric and generative processes for the design of projects such as stadiums and exposition halls. A combination of ambitious intent and fast project schedules necessitates the use of advanced parametric tools to quickly solve complex problems, generate unique features, and automate parts of the design process. Designers will utilize digital tools for a variety of purposes, which can be classified under two general categories. The first and most common application of the technology is within the category of rationalization and optimization. The tool, in this case, is limited to the role of a production device that aids the designer in efficiently solving complex design problems. In more unique projects, the advanced technology acts as a generative tool and is an integral part of a working design methodology. In this case, the design technology becomes more than just a tool at the designer’s disposal. Rather, it has the potential to act as a critical lens for identifying new possibilities in the architecture.

summary	Mesh segmentation has become an important and well-researched topic in computational geometry in recent years (Agathos et al. 2008). As a result, a number of new approaches have been developed that have led to innovations in a diverse set of problems in computer graphics (CG) (Sharmir 2008). Specifically, a range of effective methods for the division of a mesh have recently been proposed, including by K-means (Shlafman et al. 2002), graph cuts (Golovinskiy and Funkhouser 2008; Katz and Tal 2003), hierarchical clustering (Garland et al. 2001; Gelfand and Guibas 2004; Golovinskiy and Funkhouser 2008), primitive fitting (Athene et al. 2004), random walks (Lai et al.), core extraction (Katz et al.) tubular multi-scale analysis (Mortara et al. 2004), spectral clustering (Liu and Zhang 2004), and critical point analysis (Lin et al. 20070, all of which depend upon a weighted graph representation, typically the dual of a given mesh (Sharmir 2008). While these approaches have been proven effective within the narrowly defined domains of application for which they have been developed (Chen 2009), they have not been brought to bear on wider classes of problems in fields outside of CG, specifically on problems relevant to generative architectural design. Given the widespread use of meshes and the utility of segmentation in GAD, by surveying the relevant and recently matured approaches to mesh segmentation in CG that share a common representation of the mesh dual, this paper identifies and takes steps to address a heretofore unrealized transfer of technology that would resolve a missed opportunity for both subject areas. Meshes are often employed by architectural designers for purposes that are distinct from and present a unique set of requirements in relation to similar applications that have enjoyed more focused study in computer science. This paper presents a survey of similar applications, including thin-sheet fabrication (Mitani and Suzuki 2004), rendering optimization (Garland et al. 2001), 3D mesh compression (Taubin et al. 1998), morphin (Shapira et al. 2008) and mesh simplification (Kalvin and Taylor 1996), and distinguish the requirements of these applications from those presented by GAD, including non-refinement in advance of the constraining of mesh geometry to planar-quad faces, and the ability to address a diversity of mesh features that may or may not be preserved. Following this survey of existing approaches and unmet needs, the authors assert that if a generalized framework for working with graph representations of meshes is developed, allowing for the interactive adjustment of edge weights, then the recent developments in mesh segmentation may be better brought to bear on GAD problems. This paper presents work toward the development of just such a framework, implemented as a plug-in for the visual programming environment Grasshopper.
