summary	Effective strategies for the design of efficient and environmentally sensitive buildings require a close collaboration between architects and engineers in the design of the building shell and environmental control systems at the outset of projects. However, it is often not practical for engineers to be involved early on in the design process. It is therefore essential that architects be able to perform preliminary energy analyses to evaluate their proposed designs prior to the major building characteristics becoming fixed. Subsequently, a need exists for a simplified energy design tool for architects. This paper discusses the limitations of existing analysis software in supporting early design explorations and proposes a framework for the development of a tool that provides decision support by permitting architects to quickly assess the performance of design alternatives.

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 Computational Medium for the Conceptual Design of Mix-Use Projects
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. 109-116
summary	Mix use development is receiving wide attention for its unique sustainable benefits. Nevertheless, the planning and designing of successful mixed use projects in today's environment is a complex matrix of skill sets and necessary collaborations between various stakeholders and design professionals. From a design point of view, architects are required to manage and coordinate large information sets, which are many time at odds with one another. The expansive space of knowledge and information is at its best vague and substantially ill-structured. A situation that continues to overburden architects mental and intellectual ability to understand, address and communicate the design issue. In the face of this complex condition, designers are gravitating towards information modeling to manage and organize the expansive data. However, is becoming increasingly evident that current building information modeling applications are less suited for early design activity due to their interrupted and rigid workflows. Against this background, this paper presents a theoretical framework for a computational medium to support the designer during early phases of exploring and investigating design alternatives for mix-use projects. The focus is on the conjecture between programming and conceptual design phase; when uncertainty and ambiguity as at its maximum, and the absence of computational support continues to be the norm. It must be noted however, the aim of the medium is not to formulate or automate design answers. Rather, to support designers by augmenting and enhancing their ability to interpret, understand, and communicate the diverse and multi-faceted design issue. In literature on interpretation, Hans-Georg Gadamer explains that understanding is contingent on an act of construction. To understand something is to construct it. In light of this explanation. To help designers understand the design issue, is to help them construct it. To this end, the computational medium discussed in this paper is conceived to model (construct) the mix-use architectural program. In effect, turning it into a dynamic and interactive information model in the form of a graph (network). This is an important development because it will enable an entirely new level of interaction between the designer and the design-problem. It will allow the designer to gather, view, query and repurpose the information in novel ways. It will offer the designer a new context to foster knowledge and understanding about the ill-structured and vague design issue. Additionally, the medium would serve well to communicate and share knowledge between the various stakeholders and design professionals. Central to the discussion are two questions: First, how can architects model the design program using a graph? Second, what is the nature of the proposed computational medium; namely, its components and defining properties?

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	Preliminary Concept Design (PCD) Tools for Laboratory Buildings, Automated Design Optimization and Assessment Embedded in Building Information Modeling (BIM) Tools.
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. 451-476.
summary	The design of laboratory buildings entails the implementation of a variety of design constraints such as building codes; design guidelines and technical requirements. The application of these requires from designers the derivation of data not explicitly available at early stages of design, at the same time there is no precise methodology to control the consistency, and accuracy of their application. Many of these constraints deal with providing secure environmental conditions for the activities inside laboratories and their repercussions both for the building occupants and population in general, these constraints mandate a strict control over the building‚Äôs Mechanical Equipment (MEP), in particular the Heating Ventilating and Air Conditioning (HVAC) system. Due to the importance of these laboratory designers are expected to assess their designs not only according spatial relationships, but also design variables such as HVAC efficiency, air pressure hierarchies, operational costs, and the possible implications of their design decisions in the biological safety of the facility. At this point in time, there are no practical methods for making these assessments, without having constant interaction with HVAC specialists. The assessment of laboratory design variables, particularly those technical in nature, such as dimensioning of ducts or energy consumption are usually performed at late stages of design. They are performed by domain experts using data manually extracted from design information, with the addition of domain specific knowledge, the evaluation is done mostly through manual calculations or building simulations. In traditional practices most expert evaluations are performed once the architectural design have been completed, the turn around of the evaluation might take hours or days depending on the methods used by the engineer, therefore reducing the possibility for design alternatives evaluation. The results of these evaluations will give clues about sizing of the HVAC equipment, and might generate the need for design reformulations, causing higher development costs and time delays. Several efforts in the development of computational tools for automated design evaluation such as wheel chair accessibility (Han, Law, Latombe, Kunz, 2002) security and circulation (Eastman, 2009), and construction codes (ww.Corenet.gov.sg) have demonstrated the capabilities of rule or parameter based building assessment; several computer applications capable of supporting HVAC engineers in system designing for late concept or design development exist, but little has been done to assess the capabilities of computer applications to support laboratory design during architectural Preliminary Concept Design(PCD) (Trcka, Hensen, 2010). Developments in CAD technologies such as Building Information Modeling (BIM) have opened doors to formal explorations in generative design using rule based or parametric modeling [7]. BIM represents buildings as a collection of objects with their own geometry, attributes, and relations. BIM also allows for the definition of objects parametrically including their relation to other model objects. BIM has enabled the development of automated rule based building evaluation (Eastman, 2009). Most of contemporary BIM applications contemplate in their default user interfaces access to design constraints and object attribute manipulations. Some even allow for the application of rules over these. Such capabilities make BIM viable platforms for automation of design data derivation and for the implementation of generative based design assessment. In this paper we analyze the possibilities provided by contemporary BIM for implementing generative based design assessment in laboratory buildings. In this schema, domain specific knowledge is embedded in to the BIM system as to make explicit design metrics that can help designers and engineers to assess the performance of design alternatives. The implementation of generative design assessments during PCD can help designers and engineers to identify design issues early in the process, reducing the number of revisions and reconfigurations in later stages of design. And generally improving design performance.

summary	The ACADIA 2010 conference will focus on the changing nature of information and its impact on architectural education, research and practice. With the ever-increasing integration of information technologies in the design laboratory, the discipline of architecture has changed profoundly in recent years. The emerging fields of digital fabrication, generative and evolutionary modeling among others, are now at the core of investigations in a growing community of digital design practitioners and researchers. ACADIA 2010 will explore the ways designers, architects, engineers and scientists collect, analyze and assemble information through computational systems that redefine the notions of design performance and optimization, evolutionary and responsive models. These notions are today inherently related to the possibilities and limitations offered by our increasing computational capabilities, and the way information shapes relations between the human, the environment, and the machine. ACADIA 2010 will gather leading practitioners, theorists, and researchers who will examine the relation that architecture has with technology and information, and how the latter propels today’s most innovative design experimentations and research. The conference will be centered on a series of peer-reviewed paper sessions and a groundbreaking exhibition including peer-reviewed projects.

title	Situated Bioclimatic Information Design: a new approach to the processing and visualization of climate data
doi	https://doi.org/10.52842/conf.acadia.2010.088
source	ACADIA 10: LIFE in:formation, On Responsive Information and Variations in Architecture [Proceedings of the 30th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-4507-3471-4] New York 21-24 October, 2010), pp. 88-96
summary	Currently, most approaches to graphic evaluative frameworks (GEFs) for the early-stage evaluation of bioclimatic design strategies adopt a design-tool metaphor, wherein a battery of analytical routines is performed by a software tool based upon a standardized weather file from which a stock set of graphic material is produced. In seeking to evaluate a broad range of climates and to address a wide variety of passive design strategies, existing climate visualization and evaluation tools position themselves far outside of the context of a situated design problem. Remaining agnostic to the particularities of site, program, tectonic system, and material behavior these tools become, by definition, generic. As a consequence, while such design-tools can be effective in evaluating particular relationships between environmental resource, demand profile, and built-system, they maintain a potential to be rendered ineffective in any outlying cases not specifically anticipated by their authors . Situated Bioclimatic Information Design (SBID) presents an alternative approach that targets a class of design strategies prominent among these outlying cases: those highly responsive to negotiation between the continually fluctuating resources within microclimates and the fluctuating demand profile of the building program. Using a custom-built weather data parser a number of diagrams and data visualizations have been produced under this approach. These visualizations are not only useful in and of themselves for aligning design strategies to specific contexts, but they also illustrate the foundations of a larger theoretical framework for the processing and visualization of climatic data for effective utilization of bioclimatic flows.

title	Parametric Design of the Vela Roof
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. 231-240
summary	Due to the increased request for representative structures and for spaces to be used independent of the weather conditions, contemporary cities increasingly integrate public covered spaces (shadowed squares and streets, courtyards, historic commercial galleries, etc.) in the urban fibre. Facing the design of large roof structures for semi outdoor spaces is increasingly common for architects and engineers. When focusing on large roofs, aesthetics, structural performance and economics often dominate the design process. However, the current increased emphasis on energy-related aspects generates new challenges. Particularly, the use of renewable energy resources needs to be confronted. In this paper we will address the subject through a case study whose design aimed at integrating performance evaluations in the very early stages of the process. The case study focuses on the so-called “Vela roof”. This roof is part of a larger project currently under construction in Bologna (Italy). The focus of the study concerns the use of on-site renewable climate (energy) resources with special attention given passive reduction of summer overheating and daylight. For these tasks a parametric model was developed to support the decision making process and the paper will present its potential with respect to performance-oriented design during the conceptual design phase of roof structure. The very first conceptual design developed by the architectural office was assumed as a starting point for the inclusion of performance criteria. In the preliminary design of the roof uncomfortable conditions were expected under the whole roof in the summer. Various strategies for improving the thermal comfort were investigated, involving a large set of combined systems. Not all of these will be detailed in this paper. Instead we will focus on the ones directly affected by the geometry of the roof. Those are mainly air flow for cooling and the reduction of solar gain, in combination with their effects on daylight. Their investigation was based on a chain of dependencies to be integrated in the design process. With respect to that, parametric modelling was used. Parametric modelling allows both geometrical entities and their relationships to be represented. These relationships are structured in a hierarchical chain of dependencies, established during the preliminary parameterization process. The independent properties of the model are usually expressed through independent parameters, and their variations generate different configurations of the model. By making use of this potential, three project scales were parametrically explored. At the large scale, parametric variations of the overall shape of the roof were investigated in relation to cooling through ventilation and here the parametric model allowed for the generation of both different configurations of the roof, including its structural morphology and variations of its structural tessellation. At the medium scale, the integration of openable modules was investigated in relation to air extraction for cooling; with respect to this, the parametric model allows exploring openings based on variations of size and distribution. At the small scale, various options were explored for the cladding system, in order to reduce the direct solar gain while still allowing the income of indirect natural light. The parametric model was used to investigate the configuration of self-shading modules and their integration in the structure. Specific emphasis will be given to the small scale. The advantages in design process and the current limits of the parametric modelling approach used here will be discussed in the paper.

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.

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.

title	Multi-touch - the future of design interaction
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. 557-572.
summary	The next major revolution for design is to bring the natural user interaction into design activities. Graphical User Interfaces (GUI) brought a new approach that was more effective compared to their conventional predecessors. In recent years, Natural User Interfaces (NUI) have advanced user experiences and multi-touch and gesture technologies provide new opportunities for a variety of potential uses in design. Much attention has been paid to leverage in the design of interactive interfaces. The mouse input and desktop screen metaphors limit the information sharing for multiple users and also delayed the direct interaction for communication between each other. This paper proposes the innovative method by integrating game engine ‘Unity3D’ with multi-touch tangible interfaces. Unity3D provides a game development tool as part of its application package that has been designed to let users to focus on creating new games. However, it does not limit the usage of area to design additional game scenarios since the benefits of Unity3D is allowing users to build 3D environments with its customizable and easy to use editor, graphical pipelines to openGL (http://unity3d.com/, 2010 ). It creates Virtual Reality (VR) environments which can simulates places in the real world, as well as the virtual environments helping architects and designers to vividly represent their design concepts through 3D visualizations, and interactive media installations in a detailed multi-sensory experience. Stereoscopic displays advanced their spatial ability while solving issues to design e.g. urban spaces. The paper presents how a multi-touch tabletop can be used for these design collaboration and communication tasks. By using natural gestures, designers can now communicate and share their ideas by manipulating the same reference simultaneously using their own input simultaneously. Further studies showed that 3Dl forms are perceived and understood more readily through haptic and proprioceptive perception of tangible representations than through visual representation alone (Gillet et al, 2005). Based on the authors’ framework presented at the last CAADFutures, the benefits of integrating 3D visualization and tactile sensory can be illustrated in this platform (Chen and Wang, 2009), For instance, more than one designer can manipulate the 3D geometry objects on tabletop directly and can communicate successfully their ideas freely without having to waiting for the next person response. It made the work more effective which increases the overall efficiency. Designers can also collect the real-time data by any change they make instantly. The possibilities of Uniy3D make designing very flexible and fun, it is deeply engaging and expressive. Furthermore, the unity3D is revolutionizing the game development industry, its breakthrough development platform for creating highly interactive 3D content on the web (http://unity3d.com/ , 2010) or similar to the interface of modern multimedia devices such as the iPhone, therefore it allows the designers to work remotely in a collaborative way to integrate the design process by using the individual mobile devices while interacting design in a common platform. In design activities, people create an external representation of a domain, often of their own ideas and understanding. This platform helps learners to make their ideas concrete and explicit, and once externalized, subsequently they reflect upon their work how well it sits the real situation. The paper demonstrates how this tabletop innovatively replaces the typical desktop metaphor. In summary, the paper addresses two major issues through samples of collaborative design: firstly presenting aspects of learners’ interactions with physical objects, whereby tangible interfaces enables them constructing expressive representations passively (Marshall, 2007), while focussing on other tasks; and secondly showing how this novel design tool allows designers to actively create constructions that might not be possible with conventional media.

title	Structure at the Velocity of Architecture
doi	https://doi.org/10.52842/conf.acadia.2010.218
source	ACADIA 10: LIFE in:formation, On Responsive Information and Variations in Architecture [Proceedings of the 30th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-4507-3471-4] New York 21-24 October, 2010), pp. 218-226
summary	This paper outlines a digital design workflow, utilized by the authors, which actively links the geometry platforms being utilized by architects with tools for structural analysis, design, form-finding, and optimization. This workflow leads to an accelerated generation and transfer of information to help guide and inform the design process. The engineering team is thus empowered to augment the architect’s design by ensuring that the design team is conscious of the structural implications of design decisions throughout the design process. A crucial element of this design process has been the dynamic linkage of parametric geometry models with structural analysis and design tools. This reduces random errors in model generation and allows more time for critical analysis evaluation. However, the ability to run a multitude of options in a compressed time frame has led to ever increasing data sets. A key component of this structural engineering workflow has become the visualization and rigorous interpretation of the data generated by the analysis process. The authors have explored visualization techniques to distill the complex analysis results into graphics that are easily discernable by all members of the design team.

summary	This paper discusses how live linkages between parametric geometry, structural analysis and optimization can be leveraged to explore an architectural massing from different perspectives of optimum assuming a set of cost and value characteristics. Broad performance measures such as program area, cladding surface and structural quantities were computed for each geometry variation and collected. Optimums from different perspectives (structure, developer, designer) were extracted for each height category and compared. To further inform and engage stakeholders, a variety of visualization and filtering techniques have been implemented. These new techniques and associated distillation of data aids the design team in understanding the design space. A script based approach towards geometry and data management has led to a shift towards active option evaluation and a more interactive approach to form exploration. A generic workflow for structural analysis, design and optimization has been implemented and this ability to engineer at a greater velocity will move the design profession towards a more collaborative and information based design environment.

summary	Recent studies in contemporary architecture have developed a variety of parameters regarding the information paradigm which have consequently brought different results and techniques to the process of architectural design. Thus, the emergence of an ecological thinking environment and its involvement in scientific matters has determined links moving beyond the conventional references that rely on information. It is characterized as an interconnected and dynamic interaction, concerning both a theoretical background and providing, at the same time, appropriate means in the architectural design process (Saggio, 2007, 117). The study is based on the assumption that Information Theory leads into a bidirectional model which is based on interaction. According to it, I want to emphasize the presence of the human body in both the architectural creation process and the use of architectural space. The aim of my study, is consequently an evaluation of how this corporeal view related to the human body, can be organized and interlinked in the process of architectural design. My hypothesis relies on the interactive process between the information paradigm and the ecological one. The integration of this corporeal view influences the whole process of architectural design, improving abilities and knowledge (Figure 1). I like to refer to this as a missing ring, as it occurs within a circular vital system with all its elements closely linked to each other and in particular, emphasizes architecture as a living being.

title	A Framework of Haptic Design Parameters for Architects: Sensory Paradox Between Content and Representation
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. 685-700.
summary	Architects‚Äîlike other designers‚Äîtend to think, know and work in a visual way. In design research, this way of knowing and working is highly valued as paramount to design expertise (Cross 1982, 2006). In case of architecture, however, it is not only a particular strength, but may as well be regarded as a serious weakness. The absence of non-visual features in traditional architectural spatial representations indicates how these are disregarded as important elements in conceiving space (Dischinger 2006). This bias towards vision, and the suppression of other senses‚Äîin the way architecture is conceived, taught and critiqued‚Äîresults in a disappearance of sensory qualities (Pallasmaa 2005). Nevertheless, if architects design with more attention to non visual senses, they are able to contribute to more inclusive environments. Indeed if an environment offers a range of sensory triggers, people with different sensory capacities are able to navigate and enjoy it. Rather than implementing as many sensory triggers as possible, the intention is to make buildings and spaces accessible and enjoyable for more people, in line with the objective of inclusive design (Clarkson et al. 2007), also called Design for All or Universal Design (Ostroff 2001). Within this overall objective, the aim of our study is to develop haptic design parameters that support architects during design in paying more attention to the role of haptics, i.e. the sense of touch, in the built environment by informing them about the haptic implications of their design decisions. In the context of our study, haptic design parameters are defined as variables that can be decided upon by designers throughout the design process, and the value of which determines the haptic characteristics of the resulting design. These characteristics are based on the expertise of people who are congenitally blind, as they are more attentive to non visual information, and of professional caregivers working with them. The parameters do not intend to be prescriptive, nor to impose a particular method. Instead they seek to facilitate a more inclusive design attitude by informing designers and helping them to think differently. As the insights from the empirical studies with people born blind and caregivers have been reported elsewhere (Authors 2010), this paper starts by outlining the haptic design parameters resulting from them. Following the classification of haptics into active, dynamic and passive touch, the built environment unfolds into surfaces that can act as ‚Äúmovement‚Äù, ‚Äúguiding‚Äù and/or ‚Äúrest‚Äù plane. Furthermore design techniques are suggested to check the haptic qualities during the design process. Subsequently, the paper reports on a focus group interview/workshop with professional architects to assess the usability of the haptic design parameters for design practice. The architects were then asked to try out the parameters in the context of a concrete design project. The reactions suggest that the participating architects immediately picked up the underlying idea of the parameters, and recognized their relevance in relation to the design project at stake, but that their representation confronts us with a sensory paradox: although the parameters question the impact of the visual in architectural design, they are meant to be used by designers, who are used to think, know and work in a visual way.

summary	The Waiheke Gateway Pavilion, designed by Stevens Lawson Architects originally for the 2010 New Zealand Venice Biennale Pavilion, was brought to fruition for the 2017 Headland Sculpture on the Gulf Sculpture trail by students from Unitec Institute of Technology. The cross disciplinary team comprised of students from architecture and construction disciplines working in conjunction with a team of industry professionals including architects, engineers, construction managers, project managers, and lecturers to bring the designed structure, an irregular spiral shape, to completion. The structure is made up of 261 unique glulam beams, to be digitally cut using computer numerical control (CNC) process. However, due to a malfunction with the institutions in-house CNC machine, an alternative hand-cut workflow approach had to be pursued requiring integration of both digital and analogue construction methods. The digitally encoded data was extracted and transferred into shop drawings and assembly diagrams for the fabrication and construction stages of design. Accessibility to the original 3D modelling software was always needed during the construction stages to provide clarity to the copious amounts of information that was transferred into print paper form. Although this design to fabrication project was challenging, the outcome was received as a triumph amongst the architecture community.

summary	Parametric software has fundamentally changed the way in which architecture is conceptualized, developed and even constructed. The ability to assign parameters or numeric variables to specific portions of a project has allowed designers the potential to test variations of their design. Small changes to a single parameter can have an exponential effect on the designed object and alter its appearance beyond original preconceptions in both positive and negative ways. Parametric software also has the ability to constrain or restrict geometry to set values, parameters or conditions. This has the benefit of allowing portions of a form to remain constant or unchanged while simultaneously allowing for a great degree of flexibility in response to a design intent. Constraining portions of a design allows architects to respond to existing or unalterable conditions by ""locking down"" information within a project and then explore those portions that can change more freely. This programmed relationship between the parameter and the form, once established, can give the illusion of minimal effort for maximum output. The ease in which geometrical form can be altered and shaped by a single variable can mislead beginning designers into thinking that the software makes these relationships for them. What is hidden, is the programming or connections needed between the parameters and the geometry in order to produce such dramatic change. Finally, thinking parametrically about design reintroduces the concept of a rigorous, intent driven, fabrication oriented practice; a practice lost in a digital era where the novelty of new tools was sufficient to produce new form. Because parametric models must have established relationships to all parts of the design, each component must have a purpose, be well thought out, and have a direct relationship to a real world object. The introduction of parametric design methodologies into an architectural pedagogy reestablishes architectural praxis in an academic setting. Students are taught to design based on creating relationships to connected components; just as they would do in a professional architectural practice. This paper outlines how Digital Project – a parametric based software – was introduced into an academic setting in an attempt reconnect the ideologies of academia with the practicalities of professional practice. In order to take full advantage of Digital Project as a parameter based software, a project that creates modular, flexible geometries was devised. Produced over one semester, the project set out to find ways of controlling designed geometry through variable parameters that allowed the initial module to be instantiated or replicated into a wall condition: maintaining a unified whole of discrete components. This paper outlines this process, the results and how the outcomes demonstrates the parametric ideologies described above.

title	Material Information: Integrating Material Characteristics and Behavior in Computational Design for Performative Wood Construction

summary	Architecture as a material practice is still predominantly based on design approaches that are characterized by a hierarchical relationship that prioritizes the generation of geometric information for the description of architectural systems and elements over material specific information. Thus, in the early design stage, the material’s innate characteristics and inherent capacities remain largely unconsidered. This is particularly evident in the way wood constructions are designed today. In comparison to most construction materials that are industrially produced and thus relatively homogeneous and isotropic, wood is profoundly different in that it is a naturally grown biological tissue with a highly differentiated material makeup . This paper will present research investigating how the transition from currently predominant modes of representational Computer Aided Design to algorithmic Computational Design allows for a significant change in employing wood’s complex anisotropic behaviour, resulting from its differentiated anatomical structure. In computational design, the relation between procedural formation, driving information, and ensuing form, enables the systematic integration of material information. This materially informed computational design processes will be explained through two research projects and the resultant prototype structures. The first project shows how an information feedback between material properties, system behaviour, the generative computational process, and robotic manufacturing allows for unfolding material-specific gestalt and tapping into the performative potential of wood. The second project focuses on embedding the unique material information and anatomical features of individual wooden elements in a continuous scanning, computational design and digital fabrication process, and thus introduces novel ways of integrating the biological variability and natural irregularities of wood in architectural design.

summary	We discuss the use of multiple design representations to enhance decision making at the early stages of design. Our particular interest is in the way in which context can be extended by two interrelated approaches: (1) the incorporation of the temporal; and (2) through the concurrent evaluation of qualitative representations and quantitative information. Outcomes from a practice survey are used to formulate approaches to the use of mixed reality (MR) technology that reflect design-specific modes of working. We propose two approaches – studio MR and site MR – reflecting the distinction between the act of design and the process of a design review. The implementation of a studio MR application and illustrative design project are presented.

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.
