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	Using Case-Based Reasoning to Aid Sustainable Design
source	CAAD - Cities - Sustainability [5th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2010 / ISBN 978-1-907349-02-7], Fez (Morocco), 19-21 October 2010, pp. 241-246
summary	Since so far there exists only one planet, sustainable design is considered the (ethical) future in all fields of design. Although both architecture and construction are being considered major emitters of green house gases, a wise design not only can lead to minimizing this impact but it can also lead to restoring and regenerating the environment to a sustainable state. This paper presents an on-going research that aims at simplifying the elements and facilitating the process of sustainable design by using case-based reasoning. This is achieved through learning from past experiences; both good and bad ones, by providing a database application with a process-friendly interface which divides the main pillars of sustainable design into categories. Each building contains different stories related to different sustainable related issues. Each story can be repeated in /linked to many buildings. By providing designers with those past experiences, it is believed that deeper-studied designs can be more easily developed. Also a deeper analysis and understanding can be further implemented and produced with less effort for experienced and non-experienced architects in sustainable design. This would also decrease the consumption of time during the design process and encourage even more designers to integrate the sustainability concept into more designs. This research discusses the influence of sustainable design within the architectural domain, and suggests a computer application that aids architects during the preliminary design processes.

title	Computational aspects of a design process: Mario Botta’s single-family house in Breganzona
doi	https://doi.org/10.52842/conf.caadria.2010.049
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 49-58
summary	The present study aims to foreground and investigate computational aspects of the design process of Mario Botta’s single-family house in Breganzona. Through the selected case, it mainly addresses the research question, “what are the computational aspects of the examined design process and what is the nature of such aspects?” or, otherwise formulated, “what aspects of such a design process could be formalised, and thus, represented or explained in computational terms?” The study primarily involves analysis and investigation of the “material”; the sketches and the drawings produced during the design process and through this material, reinterpretation, and hypothetical reconstruction of the process. The material is taken as the container of design ideas / concepts and operations, and a formal / conceptual analysis is employed to foreground and extract this content.

title	Surface Symmetries: The Smith House Revisited
source	International Journal of Architectural Computing vol. 8 - no. 4, p. 485
summary	This work proposes the use of partial order lattices along with representational schemes to account for patterns of ambiguity and emergence in the description of designs. The complexity of such designs is viewed as an aggregation of spatial layers that can all be decomposed by the subgroup relations of the symmetry of the configuration. At the end, this methodology points to a combinatorial approach that generates visual prototypes for future use in design synthesis. Here, Meier's work is just a case study that validates the group theoretical approach.

title	Algorithm Aided Architectural Design (Aaad)
source	CAAD - Cities - Sustainability [5th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2010 / ISBN 978-1-907349-02-7], Fez (Morocco), 19-21 October 2010, pp. 117-126
summary	Algorithm Aided Architectural Design (AAAD) is considered a second paradigm shift in the Architectural design process after the first one of bridging the conventional design process to the digital realm of design. This paper is divided into two parts, the first part comprehends the Algorithmic Architecture approach of from the point of view of tools, techniques, theories and practice in order to find the Algotecture theories on the map of Digital Architecture. Then, the paper exemplifies an application on Algorithmic Architecture. FALLINGWATER TOOLBOX VERSION 1.0 is a computational design demo tool for architects to aid in the house schematic design phase according to an analytical study of Frank Lloyd Wright's basic design rules and spatial program of his masterpiece; FallingWater House, (Edgar J. Kaufmann family house 1939). These rules have been transferred to algorithms and code thereafter. At a preceding stage, the Graphical User Interface (GUI) was developed using MAXScript 9.0. Using the FALLINGWATER TOOLBOX, infinite number of house prototypes can be generated within few minutes. Although, the FWT is based on a hypothetical design problem of producing prototype alternatives for a new house with the same identity of the Edgar Kaufmann House, the concept of the tool can be applied on a wider range of problems. It may help generating prototype alternative solutions for residential compounds design according to the required constraints.

title	Generative House: Exploration of Digital Fabrication and Generative System for Low - cost Housing in Southern Brazil
source	SIGraDi 2010_Proceedings of the 14th Congress of the Iberoamerican Society of Digital Graphics, pp. Bogotá, Colombia, November 17-19, 2010, pp. 384-387
summary	Generative House is a collaborative exploration of advanced technologies for lower - and working - class housing carried out by industrial and academic partners in southern Brazil. It seeks to test generative procedures and digital manufacturing to develop a flexible building system for low - cost sustainable housing in order to inspire future developments in this field by developing an urban grammar through manufacturing models and generative programming, as well as parametric design of panels assembled using digital fabrication. Scale models and full - scale prototype with timber boards have been built, demonstrating the feasibility of the approach proposed. However, further refinement of the adopted procedures and technical applications is required.

title	Analogue Automation - The Gateway Pavilion for Headland Sculpture on the Gulf
doi	https://doi.org/10.52842/conf.ecaade.2017.2.347
source	Fioravanti, A, Cursi, S, Elahmar, S, Gargaro, S, Loffreda, G, Novembri, G, Trento, A (eds.), ShoCK! - Sharing Computational Knowledge! - Proceedings of the 35th eCAADe Conference - Volume 2, Sapienza University of Rome, Rome, Italy, 20-22 September 2017, pp. 347-354
summary	The Waiheke Gateway Pavilion, designed by Stevens Lawson Architects originally for the 2010 New Zealand Venice Biennale Pavilion, was brought to fruition for the 2017 Headland Sculpture on the Gulf Sculpture trail by students from Unitec Institute of Technology. The cross disciplinary team comprised of students from architecture and construction disciplines working in conjunction with a team of industry professionals including architects, engineers, construction managers, project managers, and lecturers to bring the designed structure, an irregular spiral shape, to completion. The structure is made up of 261 unique glulam beams, to be digitally cut using computer numerical control (CNC) process. However, due to a malfunction with the institutions in-house CNC machine, an alternative hand-cut workflow approach had to be pursued requiring integration of both digital and analogue construction methods. The digitally encoded data was extracted and transferred into shop drawings and assembly diagrams for the fabrication and construction stages of design. Accessibility to the original 3D modelling software was always needed during the construction stages to provide clarity to the copious amounts of information that was transferred into print paper form. Although this design to fabrication project was challenging, the outcome was received as a triumph amongst the architecture community.

title	Digital tea house: Japanese tea ceremony as a pretext for exploring parametric design and digital fabrication in architectural education
doi	https://doi.org/10.52842/conf.caadria.2011.071
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. 71-80
summary	This paper reviews the Digital Tea House, a joint workshop in August of 2010 held at the University of Tokyo, Department of Architecture, together with Columbia University GSAPP. Three pavilions for hosting ceremony were designed and built in less than one month, in an attempt to bridge technology and culture not only through design but also fabrication. Issues addressed in the process included applications of computational design, interpretations of tradition and culture in spatial or activity oriented expressions, structural stability, to practical solutions for quick physical materialization. Three teams comprised of 6 to 8 students, each a blend of different nationalities, ultimately produced 3 full-scale tea houses with the same software, primary material, budget, and principal fabrication method.

title	Collaborative 3D Modelling and Printing: What You See Is Not Directly What You Get
doi	https://doi.org/10.52842/conf.ecaade.2010.031
source	FUTURE CITIES [28th eCAADe Conference Proceedings / ISBN 978-0-9541183-9-6] ETH Zurich (Switzerland) 15-18 September 2010, pp.31-40
summary	The aim of this collaborative 3D printing workshop is to define the production specifications, the teaching-learning pedagogical strategy aspects to help architecture students acquire: the basic competences of building representation, the pre and post processing of printing procedures (printing materials, paint, epoxy, accessories, etc...), defining the missing functions in BIM and Architectural Modelling software and determining the benefits of enhancing them for better 3D prototyping productivity. Two teams (A and B) adopted specific working scenarios based on real world printing jobs. Team A worked on an in-house scenario and Team B on an outsourcing scenario. Tasks successfully completed showed: the wide range of prototypes that could be produced in an architectural studio and the need for a collaborative network to organize the knowledge and good practices developed by research teams (professional or academic) involved in developing rapid prototyping for architecture. This knowledge network could be a discussion forum and a development partnership of 3D printing manufacturers and CAD/BIM software developers.

title	Parametric Performative Systems: Designing a Bioclimatic Responsive Skin
source	International Journal of Architectural Computing vol. 8 - no. 3, pp. 279-300
summary	This paper assumes the façade as an innovative element of interaction between the inside and the outside: the architectural skin. As in nature, one of its most significant functions is the energy exchange with the environment. Similarly, efficiency increases by passive and active responses to climate conditions and site orientation. This research explores the potential of parametric techniques, programming and digital manufacturing, to design and build a Bioclimatic Responsive Skin (BRS). Firstly, we designed a bio-component applicable to any surface due to its parametric nature. Secondly, we fabricated two non-reactive working prototypes to study the manufacturing and construction details. Thirdly, we integrated the physical and the digital interfaces by using Generative Components™, Arduino, and Ubimash to generate a kinetic responsive model. This prototype was presented at SmartGeometry Workshop and Conference 2010. Finally, Lem3a architecture used this BRS in a real design project for a Sustainable house in New Hope, PA.

source	SIGraDi 2010_Proceedings of the 14th Congress of the Iberoamerican Society of Digital Graphics, pp. Bogotá, Colombia, November 17-19, 2010, pp. 268-271
summary	The Solar Decathlon is an academic competition of houses powered exclusively by the sun. Around twenty university teams have been called on to build more sustainable and efficient solar houses. This paper presents some challenges of the design and construction process of the Brazilian team for the Solar Decathlon in Europe. The challenges focused on in this paper refer to the search for technologies and strategies for the creative integration and collaboration of more than 100 members from six universities and different research areas. Collaboration is one of the main objectives of the event and probably the greatest challenge among the participant teams.

title	Open architectural design: an approach to managing complexity and uncertainty in an open design process
doi	https://doi.org/10.52842/conf.caadria.2010.629
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 629-638
summary	By open exchange of ideas and artifacts and non apriori hierarchical processes, Open Strategies enable a better usage of distributed resources, and the release of more creative potential. Applying these Open Strategies to the architectural design process, is goal of our project. The technical basis for our research is FREAC, a software framework developed in-house which provides a collaboration space for co-operation between different users and tools. This framework is designed not just for exchanging the outcome of the design process but also for opening up the design process itself and making it more transparent. Such highly open and distributed design processes, however, also present new problems and uncertainties which need to be taken into account in order to reach successful design outcomes. As a result proposals for the management of such processes need to be developed that facilitate collaborative work but do not unnecessarily constrain the inherent complexity of the design process. The actor-network theory, and other different management concepts, provides a theoretical underpinning for our approach. The project is a collaboration between the fields of computer science in architecture and media management.
