summary	The role of the architect is quite literally one of assembly: synthesizing the various parts of a project into a cohesive whole. It is a difficult job, often requiring the architect to weave many seemingly contradictory concerns into a solution that benefits them all. It is not surprising then, that the many elegant and effective systems found in nature should be inspiring to the architect. Emerging fields like biomimicry and systems dynamics model the patterns of interaction between organisms and their environments in terms of dynamic part to part and part to whole relationships. ¶ Observations of real relationships between organisms and their environments, as they exist in nature, reveal complex feedback loops working across multiple scales. These feedback loops operate by the simultaneous action of two observed phenomena. The first is the classic phenotypic relationship seen when organisms of the same genetic makeup instantiate differently based upon differences in their environment. This is the relationship that was originally proposed by Charles Darwin in his theory of natural selection of 1859. Darwin’s model is unidirectional: the organism adapts to its environment, but not the other way around. It operates at the local scale as individual parts react to the conditions of the whole. (Canguilhem, 1952). ¶ The second phenomenon, which sees its effect at the global scale, is the individual’s role as consumer and producer in the flows of energy and material that surround it. It is the subtle and incremental influence of the organism upon its environment, the results of which are often invisible until they reach a catastrophic threshold, at which point all organisms in the system feel global changes. ; The research presented in this paper addresses the dialectic between organism and environment as each responds reciprocally to the others’ changing state. Such feedback loops act in a non-linear fashion, across nested scales in biological systems. They can be modeled to act that way in a digital design process as well. This research is an exploration into one such model and its application to architecture: the simple communication between organisms as they affect and are affected by their environments through the use of signal chemicals.

title	Material & Space: Synthesis Strategies based on Evolutionary Developmental Biology
doi	https://doi.org/10.52842/conf.acadia.2008.066
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, 66-71
summary	A material system can be defined as a set of self-organized materials, defining a certain spatial arrangement. In architecture, this material arrangement acts as a threshold for space, though space often only appears as a by-product of the material organization. Treating space as a resulting, therefore secondary, independent product minimizes the capacity to generate architecture that is astutely aware of concerns of functionality, environment and energy. An effective arrangement of material can only be determined in relation to the spaces that it defines. When proposing a more critical approach, a material system can be seen as an intimate inter-connection and reciprocal exchange between the material construct and the spatial conditions. It is necessary to re-define material system as a system that coevolves spatial and material configurations through analysis of the resultant whole, in a process of integration and evaluation. ¶ With this understanding of material system comes an expansion in the number of criteria that are simultaneously engaged in the evolution of the design. The material characteristics, as well as the spatial components and forces (external and internal), are pressures onto the arrangement of material and space. ¶ This brings a high degree of complexity to the process. Biological systems are built on methods that resolve complex interactions through sets of simple yet extensible rules. Evolutionary Developmental Biology explains how growth is an interconnected process of external forces registering fitness into a fixed catalogue of morphological genetic tools. Translating the specific framework for biological growth into computational processes, allows the pursuit of an architecture that is fully informed by the interaction of space and material.

title	Creative Design Between Representation and Simulation
source	CAAD \| INNOVATION \| PRACTICE [6th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2012 / ISBN 978-99958-2-063-3], Manama (Kingdom of Bahrain), 21-23 February 2012, pp. 11-12
summary	Milestone figures of architecture all have their different views on what comes first, form or function. They also vary in their definitions of creativity. Apparently, creativity is very strongly related to ideas and how they can be generated. It is also correlated with the process of thinking and developing. Creative products, whether architectural or otherwise, and whether tangible or intangible, are originated from ‘good ideas’ (Elnokaly, Elseragy and Alsaadani, 2008). On one hand, not any idea, or any good idea, can be considered creative but, on the other hand, any creative result can be traced back to a good idea that initiated it in the beginning (Goldschmit and Tatsa, 2005). Creativity in literature, music and other forms of art is immeasurable and unbounded by constraints of physical reality. Musicians, painters and sculptors do not create within tight restrictions. They create what becomes their own mind’s intellectual property, and viewers or listeners are free to interpret these creations from whichever angle they choose. However, this is not the case with architects, whose creations and creative products are always bound with different physical constraints that may be related to the building location, social and cultural values related to the context, environmental performance and energy efficiency, and many more (Elnokaly, Elseragy and Alsaadani, 2008). Remarkably, over the last three decades computers have dominated in almost all areas of design, taking over the burden of repetitive tasks so that the designers and students can focus on the act of creation. Computer aided design has been used for a long time as a tool of drafting, however in this last decade this tool of representation is being replaced by simulation in different areas such as simulation of form, function and environment. Thus, the crafting of objects is moving towards the generation of forms and integrated systems through designer-authored computational processes. The emergence and adoption of computational technologies has significantly changed design and design education beyond the replacement of drawing boards with computers or pens and paper with computer-aided design (CAD) computer-aided engineering (CAE) applications. This paper highlights the influence of the evolving transformation from Computer Aided Design (CAD) to Computational Design (CD) and how this presents a profound shift in creative design thinking and education. Computational-based design and simulation represent new tools that encourage designers and artists to continue progression of novel modes of design thinking and creativity for the 21st century designers. Today computational design calls for new ideas that will transcend conventional boundaries and support creative insights through design and into design. However, it is still believed that in architecture education one should not replace the design process and creative thinking at early stages by software tools that shape both process and final product which may become a limitation for creative designs to adapt to the decisions and metaphors chosen by the simulation tool. This paper explores the development of Computer Aided Design (CAD) to Computational Design (CD) Tools and their impact on contemporary design education and creative design.

title	Digital Design for Disassembly
doi	https://doi.org/10.52842/conf.ecaade.2015.2.371
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 2, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 371-382
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	The Thermal Organism And Architecture
doi	https://doi.org/10.52842/conf.acadia.2008.192
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, 192-199
summary	Throughout the history of architectural discourse the concept of metabolic function in a building and a buildings relationship to its creators is expressed by keen designers who understand the subtle linkage. Organistic homeostasis is a biological function found in all mammals including humans. The interior generation of heat classifies man as endothermic. Endothermic heat generation allows for a very controlled equilibrium and is a characteristic of more complex organisms. The body has produced highly evolved surface systems to help efficiently manage the flow of heat energy in and out of the body. I suggest building envelopes represent the human being projecting itself outwards in a prosthetic extension of the skin. Inherent in this projection are the same demands of envelope put forth in the body. In my research of anatomy I have found one system that has evolved to help facilitate endothermic heat regulation in mammals at the skin level, which is hair. How does hair transcribe into architecture? An analysis into the function of hair and its adaptable morphologies is studied. Hair is a thermal regulating system, its building equivalent are forms of thermal insulation and radiant barriers. Hairs goal is homeostatic equilibrium which has its architectural counterpoint known as the balance point. Hair is an adjustable system that mitigates between internal and external heat loading which is the goal of a building envelope. In conclusion the paper explores these issues and more in new building systems and design tactics that originate from the function of hair.

title	Digitally Mediated Regional Building Cultures
source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 91-98
summary	Designs are complex energy and material systems and products of diverse cultural, economic, and environmental conditions that engage with their extended context. This approach relates architecture to the discourse on complexity. The design research described in this paper introduces an extended definition of ecology that expands the scope of design discourse beyond the environmental performance of materials and types of construction to broader cultural considerations. Parallel to enabling rich formal explorations, digital modeling and fabrication tools provide a basis for engaging with complex ecologies within which design and building exist. Innovative design applications of digital media emphasize interdependencies between new design methods and their particular context in material science, economy, and culture. In British Columbia, influences of fabrication and building technology are evident in the development of a regional cultural identity that is characterized by wood construction. While embracing digital technology as a key to future development and geographic identity, three collaborative digital wood fabrication projects illustrate distinctions between concepts of complexity and responsiveness and their application in design and construction.

title	Balancing Design and Performance in Building Retrofitting: A Case Study Based on Parametric Modeling
doi	https://doi.org/10.52842/conf.acadia.2008.214
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, 214-221
summary	Retrofitting the existing building stock will become one of the key fields of action for architects in the future. Due to the raised awareness of CO2 emissions related to the energy consumption of buildings, architects have to increasingly consider parameters influencing the energy performance of their retrofit designs. This is a complex task especially in the early design stages as multiple dependencies between building form, construction and technical systems influence overall energy performance. The inability to cope with this complexity often leads to simple solutions such as the application of massive insulation on the outside, neglecting aesthetic expression and design flexibility. Digital models storing multidisciplinary building information make it possible to include performance parameters throughout the architectural design process. In addition to the geometric parameters constituting the form, semantic and topological parameters define building element properties and their dependencies. This offers an integrated view of the building. We present a case study utilizing mulit-parametric façade elements within a building information model for an integrated design approach. The case study is based on a retrofit project of a multi-family house with very poor energy performance. Within a design workshop a parametric building model was used for the development of the designs. An integrated analysis tool allowed an immediate performance assessment without importing or exporting building data. The students were able to freely define geometric and performance parameters to develop their design solution. Balancing between formal expression and energy performance lead to integrated design sketches, resulting in surprising solutions for the given design task.

title	Simulation model of heat and power demand in aGerman region until 2030Stuttgart Metropolitan Region as case study

summary	Energy demand is a major concern for the future of European Cities. Resource availability and costs, climate change, and their consequences are directly related with the energy consumption in our cities. In 2007 already more than half of the world population live in cities, and cities are the main consumers of energy. The model presented in this paper explores the possibility of estimate the demand of end energy (heat and power) by simulating with a cellular automaton land use changes in a German region, in this case, Stuttgart Metropolitan Region. Several approaches deal with problems due to data availability, non-spatial information sources, aggregation levels, quality and consistence of data, among others. This case study shows that a non-deterministic simulation model of energy demand related to urban growth is already feasible, with several constraints. Otherwise, the energy demand calculations differ in great manner depending on consumption sectors (residential, commercial, industrial, transport) and all these calculation models should be further improved. Software and hardware constraints have been as well identified, and stressed in the conclusions.

summary	The association of complexity and geometry was the starting point for an academic project at the chair of Computer Aided Design in Detmold. The students were asked to analyze a complex structure - taken from nature, art, technology or society - regarding the underlying geometrical rules and principles. The translation of these abstract geometric principles (logarithmic spiral, polyhedron, rotational solids, mesh-work, double helix…) into a three-dimensional structure was then realized in Rhinoceros. The 3D-modeling was followed by a transformation- and optimization-process of the initial shape by using the evolutionary principles of mutation and selection. The set-up for these variations followed predefined rules and principles for the manipulation of the original structure.

summary	The art and craft of design and creation of buildings is undergoing a radical paradigm shift. This shift is being driven by diverse novel cross-disciplinary technical possibilities, as well as by ongoing cultural transformations. They all, directly or indirectly, originate from omnipresent advancements in information technologies. Instant and ubiquitous availability of information and immediate access to computing power pervasively penetrating our lives is profoundly transforming our culture. This phenomenon has enormous implications for architecture in a multitude of ways1. ¶ Firstly, the speed of changes that occur in modern-day culture and society makes it inconvenient or even entirely impossible to design buildings with fixed and permanent functionalities. As lifestyle patterns, production methods and environmental conditions, to name a few factors only, may now dramatically change from one day to another, architecture has to become flexible. It has to allow dynamic, active, or even pro-active adaptation and customization of spaces on many levels of its functionality2. ¶ Secondly, these profound cultural changes are not only of technical relevance. In its process-driven character, information technology strongly mandates the already widely recognized ontology of becoming, proclaimed by the prominent minds of contemporary philosophy and science. This process-oriented worldview, supported by latest technological possibilities3, has caused a radical change in the common sense of the manner in which architecture has to be understood and dealt with4. As an effect, it requires an in-depth reconsideration of the nature of processes of both creation and participation in spatial environments.

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 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.

summary	Environmental and residential destruction caused by urbanization and land development raises a serious issue. In addition, advanced technology has quickly changed the structure of cities, followed by revolutionary changes are growing faster these days and this requires us to turn our attention into developing a symbiotic eco-city, which will make it possible for further sustainable development. In this regard, it grows much more important to manage a flood of information from various intelligent devices and systems for environmental maintenance. The structure and meaning of modern info-oriented cities have changed their focus from tangible materials and resources, or energy into intangible information and knowledge. Now it has become the most important on how to manage and utilize a vast amount of information in order to strengthen the competitiveness and improve the life quality. This study finds methods for an effective city management and planning, or visualization of information for ecology-friendly education in order to provide a comfortable city life and develop a cleaner city, by efficiently managing information on several ecology protection areas and their sauces of pollution in the centre of a city. The goal is to help city managers or planners to be better aware of environmental information related to their work.

title	Developing Concrete Polymer Building Components for 3D Printing

summary	The creation of building components that can be seen as sustainable, inexpensive, stronger, recyclable, customizable and perhaps even reparable to the environment is an urgent, and critical focus of architectural research. In the U.S. alone, the construction industry produced 143.5 million tons of building-related construction and demolition debris in 2008, and buildings, in their consumption of energy produce more greenhouse gasses than automobiles or industry.Because the inherent nature of 3D printing opens new possibilities for shaping materials, the process will reshape the way we think about architectural building components. Digital materiality, a term coined by Italian and Swiss architects Fabio Gramazio and Matthias Kohler, describes materiality increasingly enriched with digital characteristics where data, material, programming and construction are interwoven (Gramazio and Kohler, 2008). The research aspires towards this classification through the use of parametric modeling tools, analytic software and quantitative and qualitative analysis. Rapid prototyping, which is the automatic construction of physical objects using additive manufacturing technology, typically employs materials intended for the immediate analysis of form, scale, and tactility. Rarely do the materials used in this process have any long-term value, nor does the process - except in rare cases with expensive metal prototyping - have the ability to create actual and sustainable working products. This research intends to alter this state of affairs by developing methods for 3D printing using concrete for the production of long-lasting performance-based components.

summary	The paper is a position paper, not a report about a research project. It concerns the paradigm-shift that is taking place in the CAAD software and its implications for the business of architecture and more importantly, for the education of future members of the profession. Twenty years ago the use of CAAD software as a replacement for hand drafting was starting. Since then the transformation is complete: hardly a final project in the universities is drawn by hand. Currently, we are witnessing a second paradigm shift and its name is BIM. The meaning of BIM is rooted in two significant differences to current CAAD software and this will have implications for teaching and practicing architecture. The first difference is the way the software structures information in the CAAD file. The standard way to save CAAD information was to organise simple geometric objects according to membership in groups and to sort them according to a layer-metaphor, which primarily controlled the visibility of the geometric elements. Three-dimensional modelling is/was nothing more than the same structure with a more complex geometry. BIM software changes this structure by storing classes of geometries and then to store the specific values of individual geometries according to factors that can be determined by external or internal logical factors. The implication for architects is that we have the chance to be the people in control of the building information model, so long as we invest the time and energy to fully understand what is happening to the building information during the planning process. If we ignore this, the real danger exists that the last control of the building’s final configuration will be usurped. As educators we are currently teaching students that will be leaving the schools in 2012 and beyond. By then, the paradigm-shift will be in full motion and so it behoves us to consider which skill sets we want the next generation of architects to possess. This means not just teaching students about how to use particular BIM software or how to program a certain parametric/genetic algorithm in a form-finding process. We need to teach our students to take the leadership in building information management and that means understanding and controlling how the building information flows, how the methodologies that are used by the consulting engineers affect our building models, and knowing what kind of logical inconsistencies (internal or external) can threaten the design intention.

summary	Buildings account for 40% of the worldwide CO2 emissions. These emissions are directly related to their energy consumption. 80% of the design decisions impacting energy consumption are made during the first 20 % of the design process and therefore address the architect. Necessary decisions do not only concern building geometry but also materialization and building service systems. Choices in either of these fields significantly influence the future energy consumption of the building. Therefore it is necessary to support the architects’ decision-making. From the first sketch on, the evaluation of energy performance needs to be incorporated into the design process. This paper shows a method and results which where produced in a case study at the ETH Zurich by using a special tool in early design phases for energy and exergy analyses.

summary	This paper presents the innovative architectural design concept, which is to integrate the new material and technology into the building design to achieve the thermal comfort and at the same time reduce the energy consumption of the building by making use of the renewable energy, including solar and wind energy. The system is developed based on the idea of regional thermal comfort in building. The advantage of the system is the environmental friendly approach, costless operation, reliability, flexibility, scalability and adaptability for the integration to the building design. With the design concept, we tried to do two application designs in two virtual sites. One is a badminton court for the 2008 Beijing Olympic Games and the other is a cooling pond in a shopping mall. We will introduce how computational simulation can contribute to the prediction of the performance of the design. We will also discuss how the computation simulation can help in the design optimization process. Through the development of the new design integration of the material to the building, we would like to feedback to the material industry to encourage further collaboration and development in the material enhancement, so that both industries and the society can benefit from the advancement.

title	Comparing district designsScreening analysis of the critical factors at the building level

summary	More and more urban designs show the appliance of low-energy techniques. Unfortunately, it is difficult to determine which one of these urban designs has the best results for energy consumption and CO2-emissions because of a lack of methods and techniques at district level. A new energy performance calculation method at district level including aspects like houses, transport and households is presented. In this paper we focus on the critical factors at the building level that should be included in a district data model. Therefore we have executed a screening analysis to indicate what the critical factors are.

title	Individual Comfort in Open-Plan OfficesA Case Study

summary	Although it was proven by many field studies of office environments that complete thermal user satisfaction can only be achieved by setting the indoor climate to individual user preferences, open-plan offices do not support this requirement. In addition, irregular occupancy of such offices leads to suboptimal energy usage. This paper will show how the design of such offices can be supported by tools that integrate individual thermal user preferences and schedules into performance simulations to test and evaluate different partitioning structures, HVAC equipment, and control strategies in regard to satisfaction and energy consumption. A case study is used as demonstrator.

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.
