title	Automated Cost Analysis of Concept Design BIM Models
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 403-418.
summary	AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs. Building parameters are integrated in the report to provide insight on the variations among design alternatives.

title	Turnstijl Houses & Cannoli Framing
source	VDM Verlag Dr. Muller Aktiengesellschaft Co. KG, Germany ISBN: 3639078470 ISBN-13: 9783639078473
summary	This work presumes that integrating modeling tools and digital fabrication technology into architectural practice will transform how we build the detached house. Single-family houses come in all shapes and sizes, and in doing so, imply variation as well in certain materials, methods, and lighter classes of structure. Ultimately, houses are extensions, if not expressions, of those dwelling within, yet our attempts to produce appealing manufactured houses have prioritized standardization over variation and fall short of this ideal. Rather than considering new offerings born of the flexibility and precision afforded by digital production, sadly, today’s homebuilders are busy using our advancing fabrication technology to hasten the production of yesterday’s home. In response to such observations, and drawing upon meta-themes (i.e., blending and transition) present in contemporary design, this study proposes a hybrid SIP/Lam framing system and a corresponding family of houses. The development of the Cannoli Framing System (CFS) through 3D and physical models culminates in the machining and testing of full-scale prototypes. Three demonstrations, branded the Turnstijl Houses, are generated via a phased process where their schema, structure, and system geometry are personalized at their conception. This work pursues the variation of type and explores the connection between type and production methodology. Additional questions are also raised and addressed, such as how is a categorical notion like type defined, affected, and even “bred”?

title	Algebras, Geometries and Algorithms, Or How Architecture fought the Law and the Law Won
source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 111-114
summary	An Architect is required to deal quite often with a restrictive piece of Building Code during his/her practice, especially in traditional and hence protected environments. The paper examines the algorithmic nature of such a Building Code and in particular the President's Decree governing the design and architecture of traditional housing in the Old Town, “Ano Poli”, in Thessaloniki Greece. The nature of the constraints and descriptions the Decree contains is algorithmic, which means that the descriptions of the constraints is procedural with a specific start and a specific finish for a house design. The problem with such descriptions in a Law is that, although an architect can develop his/her own interpretations of the traditional language of the area, or even be able to trace his/her designs using shape grammars derived from traditional buildings preserved until today, the final result cannot be approved for a building permit since it does not comply with the Presidential Decree. We suggest that the nature of such legislation should be algebraic in nature and not algorithmic, since algebras allow an amount of freedom in development of architectural language while also permitting the restriction of scale, height and so on. This coupling of architectural design freedom and effective restriction on metrics of new buildings contained in algebraic systems can be shown to be much more effective than the established algorithmic system. The Decree's content comprises of regulations concerning the volume, form and use of new buildings in the protected and conserved built environment of “Ano Poli” in Thessaloniki.

title	Digital Design for Disassembly
doi	https://doi.org/10.52842/conf.ecaade.2015.2.371

summary	The construction and building sector is now widely known to be one of the biggest energy consumers, carbon emitters, and creators of waste. Some architectural agendas for sustainability focus on energy efficiency of buildings that minimize their energy intake during their lifetime - through the use of more efficient mechanical systems or more insulative wall systems. One issue with these sustainability models is that they often ignore the hierarchy of energy within architectural design. The focus on the efficiency is but one aspect or system of the building assembly, when compared to the effectiveness of the whole, which often leads to ad-hoc ecology and results in the all too familiar “law of unintended consequences” (Merton, 1936). As soon as adhesive is used to connect two materials, a piece of trash is created. If designers treat material as energy, and want to use energy responsibly, they can prolong the lifetime of building material by designing for disassembly. By changing the nature of the physical relationship between materials, buildings can be reconfigured and repurposed all the while keeping materials out of a landfill. The use of smart joinery to create building assemblies which can be disassembled, has a milieu of new possibilities created through the use of digital manufacturing equipment. These tools afford designers and manufacturers the ability to create individual joints of a variety of types, which perform as well or better than conventional systems. The concept of design for disassembly is a recognizable goal of industrial design and manufacturing, but for Architecture it remains a novel approach. A classic example is Kieran Timberlake's Loblolly House, which employed material assemblies “that are detailed for on-site assembly as well as future disassembly and redeployment” (Flat, Inc, 2008). The use of nearly ubiquitous digital manufacturing tools helps designers create highly functional, precise and effective methods of connection which afford a building to be taken apart and reused or reassembled into alternative configurations or for alternative uses. This paper will survey alternative energy strategies made available through joinery using digital manufacturing and design methods, and will evaluate these strategies in their ability to create diassemblable materials which therefore use less energy - or minimize the entropy of energy over the life-cycle of the material.

title	Construction of a design support system for the public space design in which a citizen participates: The interactive design system in a workshop
doi	https://doi.org/10.52842/conf.caadria.2008.426

summary	Workshops are held with local residents’ participation as one technique by which residents plan roads and places along a route. Because residents without special knowledge participate in such workshops, it is necessary to show the contents intelligibly so that all participants might grasp the plan contents and examine them. Moreover, for community planning workshops, because the time during which they can be held is restricted, within that time, plan- related information must be organized efficiently for rapid examination and searching of its contents. As an interactive system, a real-time simulation (RS) is sought that allows rapid drawing and that has a structure to display the contents of a plan using a three-dimensional space model in real time. The purpose of this research is to build a system that supports environmental space design, which uses RS in the workshop, and which is applicable for evaluation of an actual street space maintenance plan.

title	Computing Spatial Qualities For Architecture
doi	https://doi.org/10.52842/conf.acadia.2008.472
source	Silicon + Skin: Biological Processes and Computation, [Proceedings of the 28th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) / ISBN 978-0-9789463-4-0] Minneapolis 16-19 October 2008, 472-477
summary	Computational representation of spatial qualities can lead us to a better understanding of how we construct spatial concepts. Analyses of spatial qualities can support architects in reasoning about the form of a configuration, helping them predict the consequences of a design. ¶ In this paper we present three definitions (enclosure, viewfield, continuity) that describe experiential qualities of architectural spaces. Our project aims to provide computable definitions to these qualities to describe common spatial experiences that are implicitly understood by architects. The description, using familiar terms, reveals the analytical structure of spatial qualities that is based on the geometry of the physical elements. ; We therefore introduce a graphic editor, Descriptor, that provides visualization of spatial qualities as the designer diagrams building elements. The system calculates perceived relationships (surrounded, visible, nearby, nearest) between a viewpoint and the architectural elements based on their geometric properties such as location and distance. The relationships are the components of the three qualities we define. We also present a use scenario to demonstrate how one might use our Descriptor system during early design. ¶ Descriptor is an attempt to formalize descriptions of the spatial qualities to help beginners understand how to make design decisions. In the future, we plan to extend the set of qualities and add detailed attributes of the physical elements to the system.

title	Study on Application of Motion Capture to Design Methodology for Generating New Geometry: Coupling Computer and Human Performance Using Motion Capture Technology for New Architectural Form and Space
doi	https://doi.org/10.52842/conf.caadria.2008.479
source	CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 479-486
summary	This research aims to develop fundamental design methodologies for human space and product design by motion capture of human activity. It is intended to generate new geometry using a motion capture system as design input device and then to develop it to design interior space and products such as furniture from data extracted from human motion. In order to produce a ubiquitous and comfortable environment, performance modeling focusing on the relationships between space and physical motion is needed. Making an object of complex shape is thought to be a new application of motion capture technology. This research proves that the numeric data of body actions can be transferred and developed to object shapes.

title	Towards a Computational Description of Urban Patterns

summary	This study is concerned with the formulation of solutions for urban problems. It departs from Alexander’s pattern language theory and urban design guidelines, to create a system for generating specifications or the ingredients of a plan, given a scale, a site and a community. It takes into account strategies, regulations, guidelines, physical features of the site, and furthermore, the social, cultural and economic characteristics of the population. This system, sorted by a sequence of events, through stages, categories, methods and agents, describes taxonomic levels and their inner relations. Such an ontology provides a pattern encoding structure towards a computational model within the capabilities provided by the spatial data modeling of GIS (GIS-O). The urban formulation model is conceived to increase qualitative inputs, reducing ambiguities, through a flexible while automate process applied to urban planning.

title	Copenhagen Elephant House: A Case Study of Digital Design Processes
doi	https://doi.org/10.52842/conf.acadia.2008.134
source	Silicon + Skin: Biological Processes and Computation, [Proceedings of the 28th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) / ISBN 978-0-9789463-4-0] Minneapolis 16-19 October 2008, 134-141
summary	This paper outlines the digital design processes involved in the design and construction of the new Elephant House at Copenhagen Zoo. Early design concepts for the canopy were tested using physical sketch models. The geometric complexity of these early physical models led to the involvement of the Specialist Modelling Group and the use of the computer to digitally sketch 3D CAD models. After many studies, the complex form of the canopies was rationalised using torus geometry. A computer program was written to generate the canopy glazing and structure. This parametric system was developed to be a design tool, and was developed by an architectural designer working with the team. Through its use the team were able to explore more design options, and alter the design farther along in the design process; however, this generative tool was created largely as a CAD efficiency tool. Another series of computer programs were written to generate and populate a shading system based on environmental analysis. Unlike the computer program that generated the structure and glazing, this program was not developed to make the generation of complex geometric structures more efficient, but developed to explore computational approaches that would have been impossible without the computer. Most of the canopy’s design was communicated to fabricator through a geometry method statement, a method that has been proven to be effective in the past. The project completed in June 2008.

summary	This paper considers the problem of detailing joints between manual and digital construction by tracking the provocations of KieranTimberlake’s SmartWrap research and the evolution of that knowledge into practical architectural instruments that can be deployed into more traditional construction projects. Over the past several years, KieranTimberlake Associates in Philadelphia has undertaken a path of research focusing on problems of contemporary construction systems and practices. One product of this research was a speculative wall system assembled for a museum exhibit. SmartWrap was to be a digitally prefabricated wall system with embedded technology. ¶ While they have yet to wrap a building with SmartWrap, KieranTimberlake have utilized a number of the construction principles and digital tools tested in the SmartWrap exhibit. One of the most important principles, prefabrication, was explored in a fast-track construction project at the Sidwell Friends School. The compressed schedule drove the design of an enclosure system which incorporated performative elements in similar categories to SmartWrap: insulation, an electrical system, view, daylighting, and a rainscreen. Besides being a prefabricated façade system, the rainscreen detailing became a formal system for organizing many other scales of the project including: site systems, thermal systems, daylighting systems, enclosure, and ornament. At a second project, a similar wood rainscreen strategy was used. However, at the Loblolly House the question of prefabrication and digital modeling was tested far more extensively: thermal systems were embedded into prefabricated floor cartridges, entire program elements – a library, kitchen, and bathroom were proposed as prefabricated systems of self-contained volume and infrastructure which were then inserted into the on-site framework. ; In all three projects the joint between manual-imprecise construction and digital-precise prefabrication became the area of richest invention (Figure 1). SmartWrap may not have yielded flexible, plastic architecture; but its conceptual and practical questions have yielded tangible implications for the design/construction processes and the built product in KieranTimberlake’s practice.

title	Elemental Methods for Integrated Architectures: Experimentation with Design Processes for Cable Net Structures
source	International Journal of Architectural Computing vol. 6 - no. 4, 453-475
summary	Tension active systems are compelling architectural structures having an intimate connection between structural performance and the arrangement of material. The direct flow of structural forces through the material makes these systems attractive and unique from an aesthetic point of view, but they are a challenge to develop from a design and an engineering perspective. Traditional methods for solving such structural systems rely on both analog modeling techniques and the use of highly advanced engineering software. The complexity and laborious nature of both processes presents a challenge for iterating through design variations. To experiment with the spacemaking capabilities of tension active systems, it is necessary to design methods that can actively couple the digital simulation with the analog methods for building the physical structure. What we propose is a designer-authored process that digitally simulates the behaviors of tension active systems using simple geometric components related to material and structural performance, activated and varied through elemental techniques of scripting. The logics for manufacturing and assembly are to be embedded in the digital generation of form. The intention is to transform what is a highly engineered system into an architectural system where investigation is as much about the determination of space and environment as it is about the arrangement of structure and material.

summary	The focus of the research presented in this paper asks how a designer can create a flexible system of physical making which can accommodate multiple programmatic functions within a smooth whole, rather than creating an a priori singular formal object. This adaptable system of construction works through the development of an intelligent CAD model that can be mapped to a flexible manufacturing mechanism, i.e. a reconfigurable mold. This system of manufacturing can be used to cast totally unique solid modules without creating a unique mold for each part by manipulating the topological structure of the system. This approach takes the notion of mass-customization beyond the expensive and unsustainable one-offs that the design world has seen recently, and into a new paradigm of a sustainable, economically viable world of mass-customizable form and space.

source	CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 437-444
summary	This paper examines the theoretical and conceptual underpinnings of digital architectural representation. Emerging digital tools, processes, and methods are sponsoring new conventions for the communication of architectural ideas and motives. New conventions yielded through digital media offer fresh and currently uncodified ways to communicate. These new conventions attempt to communicate the same ideas as the old, sometimes subverting the imperative for drawing as the representation does not refer to information in the abstract, but literally is the information. This research explores the use of architectural conventions, such as plan, section, and perspective, to examine re-presentation—not only a way to convey form and content, but to also to be used as a form of communication. The emerging digital conventions are forms of communication situated between representation and re-presentation.

A computational framework was developed that generates the designs of the original textile blocks in combination with all possible wallpaper symmetry patterns. This computational framework allowed for the creation of the catalog of possible regular patterns. The development of the framework allowed for a deeper understanding of the symmetrical relationships of the blocks and the wallpaper patterns created by Frank Lloyd Wright and a large collection of new ones.

summary	Urban Design processes need to adopt flexible and adaptive procedures to respond to the evolving demands of the contemporary city. To support such dynamic processes, a specific design methodology and a supporting tool are needed. This design methodology considers the development of a design system rather than a single design solution. It is based on patterns and shape grammars. The idea is to link the descriptions of each pattern to specific shape rules inducing the generation of formal solutions that satisfy the pattern. The methodology explores, from the urban designer point of view, the capacity of a shape grammar to codify and generate urban form (Duarte et al, 2007). This paper defines the ontology of urban entities to build on a GIS platform the topology describing the various components of the city structure. By choosing different sets of patterns the designer defines his vision for a specific context. The patterns are explicated into shape rules that encode the designer’s interpretation of the pattern, and operate on this ontology of urban entities generating solutions that satisfy the pattern’s concept. Some examples of the topological relations are shown.

summary	MxR—pronounced “mixer”—is a Mixed/Augmented Reality system intended to support collaboration during early phases of architectural design. MxR allows an interdisciplinary group of practitioners and stakeholders to gather around a table, discuss and test different hypotheses, visualize results, simulate different physical systems, and generate simple forms. MxR is also a test-bed for collaborative interactions and demonstrates different configuration potentials, from exploration of individual alternatives to group discussion around a physical model. As a MR-VR transitional interface, MxR allows for movement along the reality-virtuality continuum, while employing a simple tangible user-interface and a MagicLens interaction technique.

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	A metallic paint scheme for an architectural wall is created using computer aided color appearance design techniques. New computer graphic hardware that allows real-time rendering of complex reflectance functions is employed to produce photo-realistic images of the metallic paint applied to the surface of the wall. An interpolation scheme is developed that permits one and two dimensional metallic shade sequences to be determined between individual bricks in a single row of the wall and between the complete rows of bricks that compose the wall. Paint formulation software, originally developed for auto refinish applications, is used to determine the paint mixtures necessary to realize the metallic colors in the design. A prototype of the wall is constructed and exhibited in a museum gallery.

summary	Utilizing the principle of multi-agent system by computer programming, the paper presents achievement of an architectural generative design tool which implements intelligent architecture design with the focus of the layout in Asian high density “Floor Area Ratio” (FAR). Applying with the software, architects can get a high density FAR planning design in several minutes. From macroscopic position of building agents in geography to encode the agents by computer programming, the paper expounds the process of the generative tool and its mathematics algorithms.

summary	The transition from conventional to sustainable building depends on a number of factors— technological, environmental, economic and social. From a computer-aided design perspective, the first two are perhaps the most significant. We are working on a project with an emphasis on developing tools, to evaluate environmental consequences for design decision-making. Our current thrust is given to reducing energy usage as well as carbon emissions in buildings.
