summary	Robots are gaining popularity in architecture. Snøhetta has recently purchased their own industrial robot, becoming one of the first architectural offices to adopt robot technology. As more and more architects are exposed to robotic fabrication, the need for easy interoperability, integration into architectural design tools and general accessibility will increase. Architects are discovering that industrial robots are much more than kinematic machines for stacking bricks, welding or milling - they are highly multifunctional and can be used for a huge variety of tasks. However, industry standard software does not provide easy solutions for allowing direct robot control right from CAAD (Computer Aided Architectural Design) systems. In this paper we will discuss existing methods of programming industrial robots, published architectural results (Gramazio and Kohler 2008) and the design of a new user interface that allows intuitive control of parametric designs and customized robotic mass production, by integrating CAM (Computer Aided Manufacturing) functions into CAAD.

title	Formation Embedded Design: A methodology for the integration of fabrication constraints into architectural design
source	ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 122-131

summary	This paper presents a methodology for the integration of fabrication constraints within the architectural design process through custom written algorithms for fabrication. The method enables the translation from three-dimensional geometry, or algorithmically produced data, into appropriately formatted machine codes for direct CNC fabrication within a single CAD modeling environment. This process is traditionally one-way with part files translated via dedicated machine programming software (CAM). By integrating the toolpath creation into the design package, with an open framework, the translation from part to machine code can be automated, parametrically driven by the generative algorithms or explicitly modeled by the user. This integrated approach opens the possibility for direct and instantaneous feedback between fabrication constraints and design intent. The potentials of the method are shown by discussing the computational workflow and process integration of a diverse set of fabrication techniques in conjunction with a KUKA 7-Axis Industrial Robot. Two-dimensional knife-cutting, large-scale additive fabrication (foam deposition), robot-mounted hot-wire cutting, and robot-assisted rod-bending are each briefly described. The productive value of this research is that it opens the possibility of a much stronger network of feedback relations between formational design processes and material and fabrication concerns.

title	Integrated Design Process for Prefabricated Façade Modules with Embedded Distributed Service Systems
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. 419-434.
summary	The awareness of the environmental impact of buildings concerning their CO2 emissions, their energy and resource consumption has raised the challenges on building design, construction and operation. Building service systems are among the main contributors to building related emissions. Their consideration already in design is therefore of growing importance. Distributed service systems represent a new paradigm towards the supply of a building with energy and matter. Being small, efficient and networked, they can be distributed within the building fabric to allow an efficiently supply of the building space. Their employment, however, affects the spatial layout, construction and resulting building performance. In order to capture the resulting complex dependencies, a strategy to integrate such systems into the architectural design process is necessary. In this work a design process is proposed, that integrates distributed service systems into building design, dissolving the classical divide between architectural design and service systems layout. Digital modelling and computational methods are employed to create and analyse design solutions, visualize performance criteria and provide the relevant data for the intended digital fabrication process. The process is exemplified using a joint university-industry case study project focusing on parametric façade modules, developed in a seamless digital process from concept to fabrication.

title	Behavior-based Computational Design Methodologies: Integrative processes for force defined material structures
source	ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 82-89
doi	https://doi.org/10.52842/conf.acadia.2011.082
summary	With the introduction of physics-based algorithms and modeling environments, design processes have been shifting from the representation of materiality to the simulation of approximate material descriptions. Such computational processes are based upon enacting physical and material behavior, such as gravity, drag, tension, bending, and inflation, within a generative modeling environment. What is often lacking from this strategy is an overall understanding of computational design; that information of increasing value and precision is generated through the development and iterative execution of specific principles and integrative mechanisms. The value of a physics-based modeling method as an information engine is often overlooked, though, as they are primarily utilized for developing representational diagrams or static geometry – inevitably translated to function outside of the physical bounds and parameters defined with the modeling process. The definition of computational design provides a link between process and a larger approach towards architecture – an integrative behavior-based process which develops dynamic specific architectural systems interrelated in their material, spatial, and environmental nature. This paper, focusing on material integration, describes the relation of a computational design approach and the technical framework for a behavior-based integrative process. The application is in the development of complex tension-active architectural systems. The material behavior of tensile meshes and surfaces is integrated and algorithmically calibrated to allow for complex geometries to be materialized as physical systems. Ultimately, this research proposes a computational structure by which material and other sorts of spatial or structural behaviors can be activated within a generative design environment.

title	InfoMatters, a multi-agent systems approach for generating performative architectural formations
source	International Journal of Architectural Computing vol. 9 - no. 3, 205-222
summary	The research paper exemplifies upon a computationally intensive inter-disciplinary research driven design investigation into spatializing the relationship between digital information and physical matter. Focusing on the development of architectural scale urban inserts, the design-research work operates on the intersection of information technology, environmental design, architecture, and computer aided manufacturing domains.The research framework revolves around developing a seamless integration of the aforementioned disciplines in order to establish iterative simulation driven methodologies for generating bottom-up sustainable architectural formations. This is achieved by establishing parametrically driven relational linkages between differential data sets (environmental, social, topological, material etc), which formulate the context (both global and local) within which the proposed project has to be designed. A selforganizing multi-agent system based simulation methodology for generating resultant spatial formations, in time, based on the impacts of the parametric relationships between the aforementioned data sets is eventually embarked upon. This implies, understanding the site as a dynamic information field within which interdependent ecology of agents (representing typology of people, program, structure, speed, desired social interaction etc) with multi-level relational affinities amongst each other as well as the dynamic urban information field. The resultant self-organized multi-agent formations are iteratively mined for identifying logical three-dimensional structural patterns or subjected to programmatic and environmental need driven additional layer of structural simulation with pre-embedded material restraints. An optimized system of multi-performative components that not only populates but also serves as an integrated structural + skin system of the results obtained from the agent based simulations (based upon the degree of inclusion/exclusion of parameters such as the amount of light, sound, wind etc) is subsequently generated. These experimental projects attained the status of self-evolving ecologies of multi-dimensional agents with embodied behavioural profiles, thus providing engaged, highly interdependent design by simulation outputs. The outputs showcase a dynamic system's driven approach towards sustainable design by stressing upon the idea of cohesively binding information and material systems from the very beginning of the design process. Such approaches help in reducing post-optimization of built form and consequently allow for rational understanding of performance criteria and its impact on formal articulations throughout the design process.

title	Using 3D Design Software, BIM and Game Engines for Architectural Historical Reconstruction
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. 493-509.
summary	The use of digital tools has become a tremendous aid in the creation of digital, historical reconstructions of architectural projects. Regular visualization techniques have been used for quite some time and they still pose interesting approaches, such as following cinematic techniques [1]. While common visualizations focus on pre-rendered graphics, it is possible to apply Game Engines [2] for real-time architectural visualization, as witnessed by [3] and [4]. In the course of our teaching and research efforts, we have collected experience with several visualization and modeling techniques, including the use of gaming engines. While the modeling of qualitative geometry for use in regular visualization already poses an elaborate effort, the preparation of models for different uses is often not trivial. Most modeling systems only support the creation of models for a single amount of detail, whereas an optimized model for a real-time system will have fairly different constraints when compared to non-real-time models for photorealistic rendering and animation. The use of parametric methods is one usable approach to tackle this complexity, as illustrated in [4]. One of the major advantages of using parametric approaches lies precisely in the possibility of using a single model to generate different geometry with control over the amount of detail. We explicitly tackle this in a Building Information Modeling (BIM) context, as to support much more than purely 3D geometry and visualization purposes. An integrated approach allows the same model to be used for technical drawings in 2D and an optimized 3D model in varying levels of detail for different visualization purposes. However, while most Building Information Modeling applications are targeted to current architectural practice, they seldom provide sufficient content for the recreation of historical models. This thus requires an extensive library of parametric, custom objects to be used and re-used for historically accurate models, which can serve multiple purposes. Finally, the approach towards the historical resources also poses interpretation problems, which we tackled using a reasonably straightforward set up of an information database, collecting facts and accuracies. This helps in the visualization of color-coded 3D models, depicting the accuracy of the model, which is a valuable graphical approach to discuss and communicate information about the historical study in an appealing format. This article will present the results of different reconstruction case studies, using a variety of design applications and discuss the inherent complexity and limitations in the process of translating an active, evolving model into an environment suitable for use in a real-time system. Especially workflow issues are identified, as the translation of the model into the game engine should be repeated several times, when the model is further refined and adapted. This used to involve a large amount of repetitive work, but the current crop of game engines have much better approaches to manage the updating of the geometry.

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

title	Collaboration Workflow Simplified: Reduction of Device Overhead for Integrated Design Collaboration
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. 591-602.
summary	Design collaboration relies on cognitive tools such as analog media and digital peripheral devices, and shows the characteristics of distributed cognition. It is a social and complex activity involving multiple agents communicating and using external cognitive tools to encode, decode, and share information in the process of collaborative task completion. The systems supporting this activity should meet the ’principle of least collaboration effort’ [4] that proposes that agents in collaboration minimize their effort in presentation and acceptance of information. Yet, current collaboration systems are dispersed mixed media that is often overloaded with representations and functionality, thus preventing seam- less information sharing. Designers are required to spend extra effort collecting information using peripheral devices and in system management when sharing information. The goal of this study is to understand these overheads in infor- mation collection and sharing using peripheral devices, and to provide designers with a supportive platform to enhance collaboration using both analog and digital media. In this paper, we first review available peripheral devices such as smart pens, digital cameras, and voice recorders, as well as existing collaboration sup- porting software systems for their benefits and deficiencies in collaboration. We then present ’DiNa’, a collaboration platform that is envisioned to improve pro- ductivity and reduce redundant work by integrating peripheral devices into the collaboration workflow. We demonstrate a possible workflow using this system through several scenarios where designers collaborate in performing a series of design tasks. We hope to bring attention to the importance least collaborative effort in designing systems to support real-world collaboration.

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.

title	Parametric materiality: Material properties as catalyst for design
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 165-174

summary	Sustainability issues are increasingly taking more prominent positions in the hierarchy of design decisions. The combination of linked digital analysis and parametric design has emerged as an integrated method of assimilating performative characteristics into design. As these “informed design” methods evolve there is an increasing ability for architectural geometry to be rationalized, whether this is for reasons of constructive optimization, or environmental and economic justification. But the macro scale approach to geometry in design is only one mediator of the designs impact in its surroundings. This paper discusses what happens when designers fundamentally question the role of materials in design, and specifically what happens when “new” materials and their performative characteristics can be modelled and implemented into the digital design decision process. These approaches are showcased in “proof of concept” projects that have been developed using digital design and production technologies, in collaboration with material scientists and industry.

doi	https://doi.org/10.52842/conf.acadia.2017.512
summary	Current developments in design-to-production workflows aim to allow architects to quickly prototype designs that result from advanced design processes while also embedding the constraints imposed by selected fabrication equipment. However, the enduring physical separation between design space and fabrication space, together with a continuous approach to both design, via NURBs modeling software, and fabrication, through irreversible material processing methods, limit the possibilities to extend the advantages of a “digital” approach (Ward 2010), such as full editability and reversibility, to physical realizations. In response to such issues, this paper proposes a processto allow the concurrent design and fabrication of discrete structures in a collaborative process between human designer and a 6-axis robotic arm. This requires the development of design and materialization procedures for discrete aggregations, including the modeling of assembly constraints, as well as the establishment of a communication platform between human and machine actors. This intends to offer methods to increase the accessibility of discrete design methodologies, as well as to hint at possibilities for overcoming the division between design and manufacturing (Carpo 2011; Bard et al. 2014), thus allowing intuitive design decisions to be integrated directly within assembly processes (Johns 2014).

doi	https://doi.org/10.52842/conf.ecaade.2020.1.219
summary	This paper presents and demonstrates a "Computational Design Sustainability" (CDS) framework, inspired by "Computational Sustainability" (CS), which is a new area in computational research (C. Gomes & Yang, 2011). CS aims to apply techniques from computer science to address sustainability problems affecting a wide range of fields from environmental sciences to social studies. While CS has been broadly embraced in environmental science, the great potential of this concept to address grand challenges and solve complex problems seems to have not been adequately explored in the built environment domain. Therefore, this paper attempts to formally investigate the application of CS in built environment research addressing different scales of design problems with computational design through proposing the new concept of CDS . These approaches are demonstrated and evaluated through a range of projects collectively conducted by the research team. CDS proposes to advance computational deign research by creating a trade-off between pillars of sustainability in an integrated multifaceted and multidisciplinary approach. The presented conceptual framework provides a formal means to critically understand and further advance these approaches in a systematic way suitable for future development and broader application.

summary	This paper proposes a new interactive design method, called the networked coding method (NC method), which can manage computational design, multi-objective optimization and digital timber fabrication in an interactive design process. First, this paper discusses several drawbacks of the conventional method for architectural design. Second, the paper describes the facilities and equipment of the fabrication laboratory where the NC method was developed. Third, the paper outlines the components of the NC method together with the design process of architectural elements, called integrated fabric 2011. Finally, the paper summarizes several advantages of the method, including the production of an architectural element called the integrated-fabric that integrates various functions into one single element. The method is shown to handle any datasets, including structural and environmental analysis, which were otherwise difficult to integrate into conventional design processes.

doi	https://doi.org/10.52842/conf.acadia.2011.114
summary	This paper proposes and describes a new methodology for the design, fabrication, and construction of unreinforced thin-shell stone vaulting through the use of algorithmic form-finding techniques and multi-axis robotic water jet cutting. The techniques build upon traditional thin-shell masonry vaulting tectonics to produce a masonry system capable of self-support during construction. The proposed methodology expands the application of thin-shell vaulting to irregular forms, has the potential to reduce the labor cost of vault construction, and opens the possibility of response to external factors such as siting constraints and environmental criteria. The intent of the research is to reignite and reanimate unreinforced compressive masonry vaulting as a contemporary building practice.

title	Designing a Systematic Experiment to Investigate the Effect of Ambient Smell on Human Emotions in the Indoor Space; Introducing a Mixed-Method Approach
source	Proceedings of the 2023 DigitalFUTURES The 5st International Conference on Computational Design and Robotic Fabrication (CDRF 2023)
doi	https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_20
summary	Studies have indicated that built environments affect all aspects of human life such as emotion, perception, behavior, health, and well-being (Cooper et al. 2011). Built environments are formed from the combination and juxtaposition of visible and invisible environmental variables. In recent years, common techniques such as virtual reality, augmented reality, digital twins, and artificial intelligence have enabled researchers in the field of architecture and urban design to simulate environmental conditions to investigate the impacts of environmental variables on humans. However, the studies conducted in this field of human comfort are mostly focused on the impact of environmental variables such as form, temperature, humidity, and sound, and in fewer studies, up-to-date methods and technologies have been used to simulate and investigate the impact of smell on humans. Most of the studies that have investigated the effect of ambient smell on humans, carried out in the discipline of architecture and urban design, have used traditional tools and methods (questionnaire, interview, observation) rather than advanced technology and tools drawing on neuroscientific knowledge and technique to measure the effectiveness of the ambient smell on human. They have used unmasked scents or real-world environments rather than being able to simulate environmental conditions. This article highlights the significance and necessity of employing simulation methods to investigate the impact of environmental smells on humans. Additionally, it presents the methodology of an experiment for studying the effect of indoor environment smells (with a case study of an office environment in the initial phases) on human emotions, utilizing a mixed-method approach. Analysis of some parts of the data from this experiment showed that exposure to the fragrance of the jasmine flower pleasant (flower) and the odor of the rotten orange peel (unpleasant) can cause changes in the electroencephalography (EEG) power across different bands among participants.

summary	The walkability of open spaces has been highlighted in current discussions about the production of designed environments in urban contexts (Matan, 2011). To contribute to this theme, this work selects the environmental comfort of open spaces as its element of study. The production of urban space was investigated, specifically in regard to urban morphology, understanding that city design directly influences environmental comfort (Jacobs, 1996). This work addresses the geographic context of low latitudes, specifically in hot and humid climate zones of Brazil, and, in this context, according to NBR 15220 (national performance standards), shading is one of the main comfort strategies, so solar incidence was the approached environmental phenomenon. Thus, this work presents a digital system that performs exploratory analysis on the correlations between urban form indicators and environmental performance indicators, specifically solar incidence. The method consists of three steps: urban form modeling (1), indicator measurement (2) and correlation analysis (3). In the first stage, different spatial sections of a city in Brazil were represented in the digital environment (1). This work’s implementation instrument is based on a City Information Modeling framework (Beirao et al., 2012). Visual Programming Interface (VPI) and Geographic Information Systems (GIS) tools were used, in addition to a Relational Database Management System (RDBMS). Then, for each urban clipping, the values of morphological indicators and the incidence of solar radiation were measured (2). Based on the values of the indicators, an exploration of their correlation was carried out by statistical methods (3). The results of the correlation analysis and their correspondent scatter plots are presented. Finally, possible applications of the results for the creation of prescriptive urban planning systems are discussed, seeking to promote a sustainable urban environment.

summary	This paper is about the fabrication process of the DesCours pavilion, a project that was realized in the context of a graduate design studio in the Fall Semester of 2010. The assembly and construction process of the pavilion will be used to show how parametric software, such as Grasshopper can inform fabrication and material systems. The paper will explain the fabrication process of a pavilion in detail and make an argument for plastic as a material that not only responds to the malleable characteristic of digital tools but also to environmental issues.

summary	This paper proposes the use of a new set of software tools, called Firefly, paired with a low-cost five-axis robotic motion controller. This serves as a new means for customized tool path creation, realtime evaluation of parametric designs using forward kinematic robotic simulations, and direct output of the programming language (RAPID code) used to control ABB industrial robots. Firefly bridges the gap between Grasshopper, a visual programming editor that runs within the Rhinoceros 3D CAD application, and physical programmable microcontrollers like the Arduino; enabling realtime data flow between the digital and physical worlds. The custom-made robotic motion controller is a portable digitizing arm designed to have the same joint and axis configuration as the ABB-IRB 140 industrial robot, enabling direct conversion of the digitized information into robotic movements. Using this tangible controller and the underlying parametric interface, this paper presents an improved workflow which directly addresses the shortfalls of multifunctional robots and enables wider adoption of the tools by architects and designers.

title	Automated Cost Analysis of Concept Design BIM Models

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

title	Methodological Approach for the Integration of Material Information and Performance in the Design Computation for Tension-Active Architectural Systems
source	RESPECTING FRAGILE PLACES [29th eCAADe Conference Proceedings / ISBN 978-9-4912070-1-3], University of Ljubljana, Faculty of Architecture (Slovenia) 21-24 September 2011, pp.799-808

summary	As computational design processes have moved from representation to simulation, the focus has shifted towards advanced integration of performance as a form defining measure. Performance, though, is often assessed purely on the level of geometry and stratified between hierarchically independent layers. When looking at tension-active membrane systems, performance is integrated across multiple levels and with only the membrane material itself, defining the structural, spatial and atmospheric qualities. The research described in this paper investigates the integrative nature of this type of lightweight structure and proposes methodologies for generating highly articulated and differentiated systems. As material is a critical component, the research focuses on a system-based approach which places priority on the inclusion of material research and parameterization into a behavior-based computational process.
