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 A Performance-Based Design Approach for Early Tall Building Form Development
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. 39-50
summary This paper presents a methodological interactive design approach within which structure is integrated into tall building form development. The approach establishes a synergy between generative and analytical tools to allow for parallel interaction of the formal and structural design considerations during the conceptual design phase. An integration of the associative modeling system, Grasshopper, and the structural analysis tool, ETABS was established, and a bi-directional feedback link between the two tools was initiated to guide the iterative from generation process. A design scenario is presented in this paper to demonstrate how the parametric generation and alteration of architectural form can be carried out based on instant feedback on the structural performance. Utilizing such a tool, architects can not only develop improved understanding of structural needs, but also realize their formal ideas structurally and materially.

summary The research presented in this paper investigates ways of providing better design applications for technologies in the field of Urban Digital Media (UDM). The work takes an emergent approach, evolving a design strategy through the early engagement of stakeholders. The paper discusses research in a design-led creative intersection between media technology, culture and the arts in the built environment. The case study discusses opportunities for the enhancement of a university campus experience, learning culture and community, through the provision of an integrated digital presence within campus architecture and urban spaces. It considers types of information architecture (Manovich, 2001) and designs for use in urban settings to create communication-rich, advanced and interactive designed spaces (Haeusler, 2009). The presented research investigates how to create a strategy for display technologies and networked communications to transform and augment the constructed reality of the built environment, allowing new formats of media activity.

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 “gingerbread houses”, 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 paper proposes Parametric Systems Modeling (PSM) as a tool for building and city planning. The outlined method is based on the Systems Modeling Language (SysML) and is intended for design, dimensioning, and optimization of buildings and cities as systems. The approach exceeds the geometric approach, considers additional information from physics, technology, as well as biology, and provides a basis for multidisciplinary analyses and simulations. Its application aims at the exploration of innovative sustainable design solutions at system level. The proposal of an innovative buildinggreenhouse-city system serves to illustrate the approach. Features of this system are closed water cycles, renewable energy use, thermo-chemical energy storage and transport of energy for heating and cooling purposes on the base of desiccants, as well as recycling of CO2 , accumulation of biomass and related soil improvement.

summary This paper explores design processes requiring the invention and implementation of customized workflows for the optimization of design information exchange. Standard workflows in design software are typically dependent upon the use of proprietary file formats to communicate design intent across the design team. Software platforms promote “one-stop-shop” proprietary approaches to BIM where all team members and consultants ideally operate within a single model environment and store information within a single file format. While the ‘single model’ approach can be effective under some circumstances, this approach is often found to be limiting when the design process calls for the integration of other design toolsets and delivery processes. This is especially true for large complex projects where multiple participants with different software requirements need to collaborate on the same design. In these cases, various non-standard ways of working are often implemented, resulting in a new means of communicating design and building information across a team. This paper will outline the impact customized workflows have on the design process at NBBJ and evaluate their potential for leading to more innovative design and integrated teams. The first study will explore and evaluate the communication and collaborative process that took place in the design development and construction documentation stages of the Hangzhou Stadium. The second study will be an overview of ongoing investigation and experimentation into customized workflows for team and data integration.

title On Connecting Panels of Freeform Building Envelopes

summary As smooth geometric shapes are very tricky to manufacture with an overall great expense this paper presents a parametrical approach how to control the joint geometry within a framework of flat panels which approximate a freeform surface using discretization. Since timber has an excellent reputation as a sustainable and regenerative material plus the fact that timber can be perfectly processed with a large variety of tools including CNC milling machines we are using cross laminated timber boards (CLT) with large and heavy members. Hence that means dealing with high forces which require geometrically exact and often complex joints, which we want to push to a high degree of automation in the design process. We establish rules and constraints between all neighboring CLT-panels. That way we control a new connector system specially designed for non-standard CLT-joints. This paper documents the status of one aspect of an ongoing research project and will also give a preview to upcoming tasks including the production of a prototype structure.

summary Cities all over the world are challenged by increasing the quality of life of urban citizens in order to ensure sustainable urban development. However, a lot of policies and planning fail in integrating environmental aspects in a way that makes them applicable for design leading to rather unsustainable developments. This paper presents an approach to integrate ecological parameters into urban design using a procedural, shape grammar driven modeling and visualization system. Design specifications and ecological goals given in the Masterplan of MASDAR City derived as an application example for the workflow. We used the concept of ecosystem services to break down the ecological process knowledge to design rules and meaningful, quantifiable spatial indicators. Our results demonstrate the application of the proposed approach covering different planning scales (district and building level). The integrated model suits as an assessment tool that can be used to test urban design alternatives on the ecological functioning as a starting point for architects.

summary This paper explores how fabrication-based criteria can be integrated into design processes through computational methods. Based on the ongoing project of the Library of the Bao’an Cultural Complex in Shenzhen, China (referred as ‘the Library’ in this paper hereafter), this paper discusses the process of the rationalisation of an intuitive architectural form and its subsequent tiling design based on the adaptation to the conventional fabrication techniques of the building façade industry in China. These objectives are followed by the establishment of robust computational systems of automation that provide a concrete basis for the visualisation, the development of envelope details, and the generation of the list of component data for fabrication. This integrative approach is markedly different from a more conventional one, in which computational systems serve as a priori solutions to unconstraint design sketches.

title Towards Changeability

summary Many buildings around the world have undergone successive changes over their life cycles. Regardless of the type or size of a building there are usually requirements for change due to several unanticipated forces and emerging uncertainties that act upon them. These changes might be in the building’s spatial, structural or service systems. This can be due to changes in the needs of occupants, the market demand or technological advances. Although buildings undergo change, current design practice does not address this and buildings are still designed as if they will remain static. This paper proposes an Adaptable Buildings Design (ABD) Framework to address the issue of adaptability in building design. Using this methodology uncertainties and future changes are first identified. To increase the building’s longevity, flexibility options are embedded and design rules are formulated to trigger these options when necessary. The value of adaptability is then assessed by implementing several simulations using Real Options Analysis (ROA). To demonstrate the approach, the ABD is applied to a multi-use commercial building case study. Flexibility is embedded in the building’s design across several systems allowing it to change and evolve over time based on a set of design rules. The buildings adaptability is then assessed using ROA. Positive results demonstrate the strength of the proposed methodology in addressing future change and uncertaintie.

summary This paper reports on the computer process to be used in an ongoing research to investigate the effect of architectural parameters of tall buildings on the incorporation of wind turbines. The process combines a generative modeling tool (Grasshopper) and a performance based CFD tool (Virtualwind). The process is demonstrated on three typical tall building plan configurations. The wind speed was simulated at certain locations to demonstrate the ability of tall buildings to enhance the wind speed and thus maximize the energy produced by wind turbines located between twin towers. The process to predict wind power production is lastly listed.

summary As issues of sustainability gain traction for architects, methodologies for designing, analyzing, and calibrating design solutions have emerged as essential areas of research and development. A number of approaches have been pursued with regard to embedding data into the design process, most fall into one of two approaches to research. The first approach is to mediate environmental impact at the level of applied technology; the second alters building methods and material construction, generating efficient energy use. However, few approaches deal with the crafting of relationships between information and performance on an architectural level. We will examine an approach focused on understanding how crafting relationships between information and design can move architecture towards achieving sustainability. In developing this approach, we created a data-driven design methodology spanning from design inception to construction. Data-driven models, common in the fields of natural science, offer a method to generate and test a multiplicity of responsive solutions. By contextualizing the solutions generated, we were able design though a set of specific and controlled responses rather than as a singular solution. Information utilization requires a new kind of craft that moves beyond instances into relationships and offers performance sensitive issues in design a focused trajectory. We applied this method to the research and development of a responsive shading structure built in conjunction with a thermal testing lab for two test locations – Austin, Texas (Figure. 1 and 2) and Munich, Germany. The following paper chronicles the design and construction at the Texas site over an academic semester.

summary The state university of Campinas, Unicamp, is a public university in upstate São Paulo, Brazil, ranked the second best in the country. It was founded in 1966, and its main campus started to be built in 1967, in the suburbs of Campinas, nowadays a two-million people city. The area of the campus is almost 3 million square meters (300 hectares), with a total built area of 522.000 m2 and a population of 40 thousand people - 30 thousand students, 2 thousand faculty members and almost 8 thousand staff members. The campus’ gross population density is 133 people per hectare. Less than 6% of the total campus area is presently occupied. The design of Unicamp's campus is based on concepts that were typical of the modern movement, with reminiscences of corbusian urbanism, in which preference is given to cars and buildings are spread apart on the territory, with little concern to the circulation of pedestrians. The standard building type that has been built on campus since the 1970's is based on non-recyclable materials, and has a poor thermal performance. Unicamp is expected to double its number of students by the year 2030. The campus density is thus expected to grow from 600 people per hectare to almost 1,000 people per hectare. The need to construct new buildings is seen as an opportunity to correct certain characteristics of the campus that are now seen as mistakes, according to sustainability principles. This paper describes a set of proposals targeting the increase of the campus' density in a sustainable way. The plan also aims at increasing the quality of life on campus and diminishing its impact on the environment. The main targets are: - Reducing the average temperature by 2oC; - Reducing the average displacement time by 15 minutes; - Increasing the campus' density by 100%; - Reducing the CO2 emissions by 50%. // In order to achieve these goals, the following actions have been proposed: Developing a new standard building for the university, incorporating sustainability issues, such as the use of renewable and/or recyclable materials, the installation of rainwater storage tanks, the use of natural ventilation for cooling, sitting the buildings in such a way to decrease thermal gain, and other issues that are required for sustainable buildings' international certifications. To assess the performance of the new standard building, different simulation software were used, such as CFD for checking ventilation, light simulation software to assess energy consumption, and so on. 1. Filling up under-utilized urban areas in the campus with new buildings, to make better use of unused infrastructure and decrease the distance between buildings. 2. Proposing new bicycle paths in and outside campus, and proposing changes in the existing bicycle path to improve its safety. 3. Developing a landscape design plan that aims at creating shaded pedestrian and bicycle passageways.

summary This paper details an initial exploration into the development of a breathing building skin. This research proposes a system of diaphragms as an alternative to the use of fans for distributing volumes of air. The driving concepts for this project are the three types of evolutionary adaptation: flexibility, acclimation, and learning. Of particular interest is how these biological concepts relate to architectural design. Parametric modeling was used throughout the project to study a family of folding geometry. This allowed for the iterative development of a complex part that is capable of being manufactured from a single sheet of material. Preliminary calculations point to this system being several times more energy efficient than a fan at moving a given volume of air per Watt of electricity. This research is significant as it puts forth a potentially energy efficient and highly integrated alternative to fans, while also illustrating a way of relating biological concepts of adaptation to architectural design.

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 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.

title Variaciones intensivas: diseño paramétrico de edificios en altura basado en análisis topológico [Intensive variations: parametric design of tall buildings based on topological analysis]
source SIGraDi 2010_Proceedings of the 14th Congress of the Iberoamerican Society of Digital Graphics, pp. Bogotá, Colombia, November 17-19, 2010, pp. 129-132
summary Several building works have demonstrated the possibilities of architectural design based on structural performance. This work discusses some examples and digital design strategies that approach this issue, as well as an exercise for a tower generated through topological optimization. That experience presents alternatives for a traditional office tower in Santiago, Chile, the Torre Santa Maria, based on generative design strategies for the incorporation of structural and environmental requirements to define parametric models. The experience and the capabilities studied reveal an intensive variation of architectural shape. This approach challenges conventional building regularity and suggests new ways of designing based on material performance.

summary In this paper we present a new parametric approach based on urban regulation, in order to generate digital models of building, directly within a three-dimensional geo-referenced environment. The system allows user, through implementation of specific generative procedures, to manage interactive architectural design processes. The designer is able to explore all possible infinite scenarios and the various possible design alternatives, by changing the parameters values and verifying in real time the results of the changes. This paper presents a short review of the main related works and an experiment.

title Augmented Reality-Based Education and Fire Protection for Traditional Korean Buildings
source International Journal of Architectural Computing vol. 8 - no. 1, 75-91
summary This study examines an application of Augmented Reality technology (AR) for Korean Cultural Traditional Buildings, specifically, the Namdaemun Gate, "National Treasure No 1" of the Republic of Korea. Unfortunately, in February 2008, the Namdaemun Gate burned down, despite the efforts of many firemen, as the main difficulty was getting the fire under control without any structural knowledge of the wooden building. Hence, with the great advances in digital technology, an application of virtual technical information to traditional buildings is needed, and the new technology of AR offers many such advantages for digital architectural design and construction fields. While AR is already being considered as new design approach for architecture, outdoor AR is another practical application that can take advantage of new wearable computer equipment (Head-mounted display also know as HMD, position and orientation sensors, and mobile computing) to superimpose virtual graphics of traditional buildings (in this case, Namdaemun Gate) in a real outdoor scene. Plus, outdoor AR also allows the user to move freely around and inside a 3D virtual construction, thereby offering important training opportunities, for example, specific structural information in the case of firemen and mission planning in the case of a real-life emergency. In this example, the proposed outdoor AR system is expected to provide important educational information on traditional wooden building for architects, archaeologists, and engineers, while also assisting firemen to protect such special buildings.

title Shaping building volumes through life cycle costs: a constraint programming approach for building volume optimisation
source Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 185-194
doi https://doi.org/10.52842/conf.caadria.2010.185
summary Due to a general freedom in the architectural design process, a wide range of possible alternatives exist; although building-volume designs must also continue to meet numerous, possibly conflicting design requirements originating from various related disciplines. This research addresses problems associated with missing quantitative design aids during the early design stages. It aims to provide designers with solutions that provide optimal cost-effectiveness. The demonstrated building-volume optimisation model minimises life cycle costs by determining optimal-volume dimensions, floor number, building orientation and ‘window / wall’ opening ratios while satisfying site and building code regulations and design constraints. Results indicate an optimal solution can be found within a practical timeframe. The proposed, novel approach to introduce cost objectives into building-volume design provides designers with a valuable decision support tool in a design domain that is known to be complex owing to multiple design criteria and constraint influences.
