summary	SSSP is a Government funded knowledge transfer project under the overall umbrella of the UK ‘building sustainable communities’ initiative. The paper describes the innovative techniques being developed by the partners to build urban modelling tools for multiple simulation or regeneration scenarios in the Thames Gateway region of London. This knowledge transfer scheme is between the main partners and the London boroughs of Newham and Tower Hamlets. The main aim is to demonstrate the use of digital data in the development of planning scenarios. The aim is to demonstrate a workflow, which should provide stakeholders with a way of testing regeneration options, which are grounded on ‘real’ data and are capable of providing rapid feedback for policy makers and inhabitants alike.

summary	This paper outlines two major aspects of virtual environments for architectural design. On the one hand it focusses on how to use virtual reality as an extended tool to generate spatial design by building up and interacting with a three-dimensional digital model. On the other hand it describes - based on a case study - the relation between perception, interaction and immersion in virtual environments. Both approaches can be interconnected to a continues design process, that allows the designer to create, manipulate, visualize and decide on spatial concepts in a holistic three-dimensional simulation.

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	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	To the east of Johnson City TX is the Lyndon B. Johnson’s family home. Part of the Johnson Estate2 is given over to a working farm circa 1870 that presents various aspects of domestic practice from the era. This includes a desert fridge which is a simple four-legged structure with a slightly battered profile that’s draped in calico. Its principle is simple; water from an upturned jar is drawn by osmosis down the sides of the calico where it evaporates in wind currents drawn though a “dog run” between two log cabins. Cooled air circulates within the structure and where cheese and milk are kept fresh during the summer. The desert fridge is a simple system that reaches a state of equilibrium through the natural process of evaporation. ¶ This system provides a working model for a prototype structure for an outdoor dining pavilion that was designed and constructed on the campus of Arizona State University. The desert fridge is the basis for a “biological process”3 of evaporative cooling that has been interpreted in terms a ritual of outdoor dining in arid climates. The pavilion is intended as a gathering point and a place of interaction for ASU freshmen. The long-term aim of this project is to provide a multiple of these pavilions across the campus that will be the locus of a sequence of dining events over a “dining season”4 during the fall and spring semester. ; This paper describes how the desert fridge principle has been interpreted in the program and construction of the dining pavilion. It explores a sequence of levels by which the structure, via digital production process, provides an educational narrative on sustainability. This communicative quality is portrayed by the building in direct biological terms, through tacit knowledge, perceived phenomena, lexical and mechanical systems. The paper also describes how these digital production process were used in the building’s design and fabrication. These range from an empirical prognosis of evaporative cooling effects, fluid dynamics, heat mapping and solar radiation analysis through to sheet steel laser cutting, folded plate construction and fully associative variable models of standard steel construction. The aim of the pavilion is to create an environment that presents the evaporative cooling message at a multiple of levels that will concentrate the visitor in holistic understanding of the processes imbued within the building.5

doi	https://doi.org/10.52842/conf.caadria.2008.053
summary	This paper discusses the preliminary findings of an ongoing research project aimed at developing a technological, operational and strategic analysis of adopting BIM in AEC/FM (Architecture-Engineering-Construction/Facility Management) industry as a collaboration tool. Outcomes of the project will provide specifications and guidelines as well as establish industry standards for implementing BIM in practice. This research primarily focuses on BIM model servers as a collaboration platform, and hence the guidelines are aimed at enhancing collaboration capabilities. This paper reports on the findings from: (1) a critical review of latest BIM literature and commercial applications, and (2) workshops with focus groups on changing work-practice, role of technology, current perception and expectations of BIM. Layout for case studies being undertaken is presented. These findings provide a base to develop comprehensive software specifications and national guidelines for BIM with particular emphasis on BIM model servers as collaboration platforms.

summary	The decision support system developed in this research is aimed to the conceptual scheme of project focusing on infrastructure planning and open space design in the architectural context for housing project. Alternative design sets are provided within the limitations, and possibilities to be further evaluated appropriately. This system helps architects and developers to analyze relationships of physical environment, architectural requirements and the overall of project-related factors with real-time cost estimation. Factors for cost estimation derived from the beginning to the end of project will be manipulated simultaneously. Architects and developers can use this design simulation to address the physical data with real-time cost estimation, provide alternative results, and design evaluation for overall project’s feasibility. The software of our research is not just a tool for design & planning automation in feasibility analysis. It will be an interactive decision support system for both developers and planners aspects. The system was developed by SketchUp Ruby Application Programming Interface. The results will be presented into two ways. Firstly, 2D and 3D modeling will be used for interactive visualization in design and planning of the beginning process. Subsequently, numbers and additional factors in details will be used to show relationship between architectural environment and feasibility-based information to help architects and developers collaboratively analyze the land use planning and open space design for housing project. In evaluation process, the developed software is tested with the project preceding and the future project of Bangkok area under constraints and regulations of Building Control Act of Thailand. In conclusion, this system will make effectiveness in design process and management of the construction knowledge. The decision support systems should be designed to makes explicit use of both planning analysis aspect and knowledge-based decision making.

title	Modelling urban dynamics through cellular automata: an empirical application
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary	Actual developments of digital maps and tools given by GIS-systems provide the possibility to develop new methodologies to handle land-cover data for modelling purposes. At any rate empirical applications are still rare within the Geosimulation studies and yet there is not an established methodology. The aim of the work has been to construct a cellular automata (CA) model of a sprawling city region within the German context, based on empirical data. The urban land-use classes (LUC) are considered as a higher organisation level of different building typologies and relative functions. These define the land-use patterns as self-organized from their complex spatial iterations, based on limited local information exchange. On the one hand the synthesis capacity of the CA models has been verified, even without socio-economical variables. On the other hand, it has been seen that the still early evolutional state of digital land-cover datasets are too premature to fully suite the modelling purposes.

title	Sketch-based Methods for Researching Building Layouts through the Semantic Fingerprint of Architecture
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. 85-102.
summary	The paper focuses on the early stages of the design process where the architect needs assistance in finding reference projects and describes different aspects of a concept for retrieving previous design solutions with similar layout characteristics. Such references are typically used to see how others have solved a similar architectural problem or simply for inspiration. Current electronic search methods use textual information rather than graphical information. The configuration of space and the relations between rooms are hard to represent using keywords, in fact transforming these spatial configurations into verbally expressed typologies tends to result in unclear and often imprecise descriptions of architecture. Nowadays, modern IT-technologies lead to fundamental changes during the process of designing buildings. Digital representations of architecture require suitable approaches to the storage, indexing and management of information as well as adequate retrieval methods. Traditionally planning information is represented in the form of floor plans, elevations, sections and textual descriptions. State of the art digital representations include renderings, computer aided design (CAD) and semantic information like Building Information Modelling (BIM) including 2D and 3D file formats such as Industry Foundation Classes (IFC) (IAI, 2010). In the paper, we examine the development of IT-technologies in the area of case-based reasoning (Richter et al., 2007) to provide a sketch-based submission and retrieval system for publishing and researching building layouts including their manipulation and subsequent use. The user interface focuses on specifying space and their relations by drawing them. This query style supports the spatial thinking approach that architects use, who often have a visual representation in mind without being able to provide an accurate description of the spatial configuration. The semantic fingerprint proposed by (Langenhan, 2008) is a description and query language for creating an index of floor plans to store meta-data about architecture, which can be used as signature for retrieving reference projects. The functional spaces, such as living room or kitchen and the relation among on another, are used to create a fingerprint. Furthermore, we propose a visual sketch-based interface (Weber et al., 2010) based on the Touch&Write paradigm (Liwicki et al., 2010) for the submission and the retrieval phase. During the submission process the architect is sketching the space-boundaries, space relations and functional coherence's. Using state of the art document analysis techniques, the architects are supported offering an automatic detection of room boundaries and their physical relations. During the retrieval the application will interpret the sketches of the architect and find reference projects based on a similarity based search utilizing the semantic fingerprint. By recommending reference projects, architects will be able to reuse collective experience which match the current requirements. The way of performing a search using a sketch as a query is a new way of thinking and working. The retrieval of 3D models based on a sketched shape are already realized in several domains. We already propose a step further, using the semantics of a spatial configuration. Observing the design process of buildings reveals that the initial design phase serves as the foundation for the quality of the later outcome. The sketch-based approach to access valuable information using the semantic fingerprint enables the user to digitally capture knowledge about architecture, to recover and reuse it in common-sense. Furthermore, automatically analysed fingerprints can put forward both commonly used as well as best practice projects. It will be possible to rate architecture according to the fingerprint of a building.

summary	Our area-images are composed of evaluations derived from the various kinds of elements or activities within different regions. In quantitative terms, the extraction of area-images is difficult. In this paper, we focus on a phenomenon in which a part of people’s area-image can be observed in the names of buildings. In the first instance, a model based on the random utility theory is constructed to describe the spatial distribution of building names. Secondly, the proposed model is calibrated using actual data from the city of Tokyo (Setagaya Ward), and effects of such area-elements or activities on area-images are then estimated. Finally, values for the area-images are quantitatively estimated and their spatial distribution is represented on a map.

summary	This paper addresses the utilization of Data Mining as an advanced technique of information technologies to investigate and identify the patterns of architectural features of contemporary architecture in Saudi Arabia in two suggested building types: houses and commercial office buildings. Such patterns will help in developing a model of patterns of architectural features that can be utilized to augment the architectural context of Saudi Arabia. The paper presents a constructed framework that provides a comprehensive analysis of recognition criteria for identifying each architectural feature of the nominated set of nine features. These architectural features include: spatial relationships, space allocation, circulation, building form, façade treatment, building structure, external finishes, environmental aspects, and cultural features. The recognition criteria for these architectural features are expressed in the attribute-value format. Such criteria are extracted for houses and commercial office buildings specifically within the context of Saudi contemporary architecture based on extensive case analysis that represents the diversity of architectural designs of houses and commercial office buildings. The paper also, introduces a process model of applying Data Mining for investigating patterns of contemporary architecture.

summary	This paper describes the translation of the process management tool ‘Kanban’ and its adjacent Toyota Production System into an architectural design supporting tool in the context of computer integrated buildings. The triggering question is: ‘How can architects handle requirements and services of ubiquitous computing in relation to their cursory knowledge about networked services and its unpredictable future development?’. The paper develops a system called ‘Ubicomp-Kanban’ based on the characteristics Toyota Production System. It is suitable for both design and operation of binary networked services in built environment in selected architectural scales and selected functions. The application of the system allows more precise planning and resource optimized operation of academic buildings. The paper does not intend to set up a new approach for building information models (BIM).

summary	This paper presents the validation of an office utilisation model for the research project called “User Simulation of Space Utilisation (USSU)”. The result of this research is a system that can be used for analysing and evaluating the space utilisation of a building for any given organisation. A system for building usage simulation that produces data about activities of members of an organisation can substantially improve the relevance and performance of building simulation tools. This is relevant for engineering domains as well as for architects to evaluate the performance of a building design. For a thorough evaluation of the system an experiment was executed for assessing its predictive quality in the context of a real building, organisation and actual human behaviour; this experiment was executed using RFID technology. The result of the experiment was observed data about the space utilisation of the selected organisation. These data were compared with the space utilisation predicted by the USSU system to evaluate the simulation model. The validation of USSU showed that there were no significant differences between the predicated and observed activity behaviour. As a consequence, the output of USSU is considered to be valid.

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	Simulation model of heat and power demand in aGerman region until 2030Stuttgart Metropolitan Region as case study
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
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	This paper presents a novel static-dynamic network based people flow simulation model applied to design optimisation of circulation spaces within buildings and urban areas. In the current state of art the majority of existing people flow simulation models are driven by analysis rather than design. This is fine for simpler, evacuation type scenarios where a single or a few analyses runs are sufficient to determine the evacuation time. For more complex scenarios such as crowd circulation with complex multi-directional flow, one is as interested in the sensitivity of various design and stochastic behavioural parameters, so the rapid modelling simulations together with design capability become important. This paper presents a simplified network based people flow model that enables rapid simulations and therefore iterative design optimization of circulation space. The work integrates the techniques of graph-theory based network analysis with an origin-destination matrix model of crowd flow, to provide a rapid, parametric model. The resulting model can be analysed in a static as well as dynamic state. In the static state, the model analyses space based on connectivity of nodes, superimposed with the origin-destination matrix of population to provide valuable information such as footfalls, density maps, as well as quasi-static parameters such as mean flow rates. In the dynamic state, the model allows time-dependent analysis of flow using a detailed agent based simulation that also incorporates dynamic route-choice modelling, agent behaviours and interaction, and stochastic variations. The paper presents the integrated modelling technique and its implementation into simulation software SMART Move.

summary	The first part of the paper is centred on the phenomena of urban growth, in order to set the rules for a sustainable scenario of urban development. Then we enter the core of the paper that is the comparison of models. For each of the three compared models, we describe its main theoretical characteristics, the chosen parameters, and the obtained results. In section 6, heterogeneity of the produced results is discussed, and we highlight the points of interest and the lacks of the three models. Here we show that results we obtained feed debates about urban growth management. Finally, concluding remarks at the end of the paper address the general topic of the evaluation of the quality of simulation results.

summary	We present a system for viewing architectural building models – specifically Building Information Modeling (BIM) models – in 3D using an Augmented Reality Tangible User Interface (TUI) and a Magic Lens interaction metaphor. ARchitectureView is meant to facilitate communication and collaboration around a shared model. We present the system overview and a number of use scenarios in which the interface would serve to improve communication across disciplines and varied technical backgrounds, while supporting a rich and coherent common understanding.

summary	Over the last decade various examples of urban 3D models have been created employing various techniques for data collection and model building. The problems faced are well documented, issues of accuracy, complexity and utility of the models has also been addressed. This paper presents a low tech approach to accurate city modeling focusing on engineering applications, browsing/experiencing applications as well as multi-layering time based analyses, historical info overlaying for use in interactive real time applications (museum exhibitions, research projects for behavioral patterns of users in 3D urban environments, marketing, tourism, etc). The pros and cons of the proposed methodology are analyzed and ways forward suggested.

title	Agent-Based System for Modeling User Behavior in Shopping Malls

summary	Agent-based systems are being used as decision support systems for solving architectural design problems. Usually in design phase, user behavior is ignored by the designers. Therefore, after the construction, the users face difficulties in emergency situations and in daily usage. As a result, buildings become insufficient to respond to users’ needs and design goals of the building itself. Before construction, ability of testing the interactions between the building and its users is particularly important to solve the problems in early phases of the design. Hence, to design a building that functions better in certain situations and time loss decreases in the design process. For these reasons, the aim of this study is to develop a model to simulate users in shopping malls.
