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 Presence in Virtual Cave

summary Virtual Reality (VR) is usually recognized as a tool that enables the viewer to move freely in a three dimensional digital environment. In this virtual world, different levels of immersion could be reached. Using VR to visualize sites and places from the past, presents and future is widely acknowledged. This study is making use of a recently installed U-Cave theatre at Birzeit University (BZU) in Palestine and a Con-Cave VR theatre at the Norwegian University of Life Sciences (UMB).In the study, we test hypotheses connected to presence in virtual reality environments, using the case of historical sites. Historical sites in general are important for reasons of cultural identification and environmental integrity. In many historical sites, it is difficult for a layperson to read and understand the meaning of the site, for that the remaining ruins don’t provide enough information. This study will contribute to improving the public understanding for historical sites by unfolding the role of Virtual Reality to overcome the harsh reality of many damaged historical sites. The story-line of the site can be easily portrayed by re-constructing the original site in a virtual environment. The study also elaborates on the enriched sense of presence made possible by implementing different levels of details in the VR environment. Presence in VR environments is usually defined as “being there”, with high consideration of the physical ether of the virtual environment, the definition confines attention to the sensation of place. This study calls for expanding the attention to the dimension of time that is made possible by innovative design of VR environment. The study argues that virtual reality technology does not only provide a 3-D experience to subjects, it can also add a fourth dimension by conveying the unconsciousness of man from the meanwhile moment to a different timeframe. Based on the current knowledge on presence in virtual environments, we will use a questionnaire to measure subjective presence for the two VR theatre systems. The study will make use of the following factors in order to determine the degree of presence in the virtual environment: (1) naturalness of interface design and involvement, (2) control and interaction, (3) quality of technical capabilities, and (4) negative effects. The outcome of the study will verify or falsify some of the following hypotheses: • There is a correlation between modeling techniques and presence. The perception of the visual experience differs between traditional media and an immersive VR environment. • A presentation of a historical site in a VR-Cave environment will increase our subject’s awareness of the identity of the historical site. • The presence level is correlated to previous real exposure. Subjects who had been to a ruined historical site in real life, would experience higher level of presence toward the VR presentation than those who had not been to the historical site in reality. • Because of the display enclosure surround effect, it is believed that presence in a Con-Cave would be higher than of U-Cave VR environment.

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

title Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative 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. 477-492.
summary Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call “business views”. We propose a 4 steps-method to compose business views. The first step identifies the users’ business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user’s interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

title Open-source, parametric architecture to propagate hyper-dense, sustainable urban communities: parametric urban dwellings for the experience economy
source Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 443-452

summary Rapid developments in societal, technological, and natural systems suggest profound changes ahead if research in panarchical systems (Holling, 2001) is to be believed. Panarchy suggests that systems, both natural and man-made, rise to the point of vulnerability then fail due to disruptive forces in a process of ‘creative destruction.’ This sequence allows for radical, and often unpredictable, renewal. Pressing sustainability concerns, burgeoning urban growth, and emergent ‘green manufacturing’ laws, suggest that future urban dwellings are headed toward Gladwell’s ‘tipping point’ (2002). Hyper-dense, sustainable, urban communities that employ open-source standards, parametric software, and web-based configurators are the new frontier for venerable visions. Open-source standards will permit the design, manufacture, and sale of highly diverse, inter-operable components to create compact urban living environments that are technologically sophisticated, sustainable, and mobile. These mass-customised dwellings, akin to branded consumer goods, will address previous shortcomings for prefabricated, mobile dwellings by stimulating consumer desire in ways that extend the arguments of both Joseph Pine (1992) and Anna Klingman (2007). Arguments presented by authors Makimoto and Manners (1997) – which assert that the adoption of digital and mobile technologies will create large-scale societal shifts – will be extended with several solutions proposed.

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.

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.

doi https://doi.org/10.52842/conf.acadia.2010.258
summary This paper presents recent research for new mechanical systems and façade designs that are able to respond to environmental changes through local interactions, inspired by biological systems. These are based on a model of distributed intelligence founded on insect and animal collectives, from which intelligent behavior emerges through simple local associations. Biological collective systems integrate material form and responsiveness and have the potential to inform new architectural and engineering strategies. The proposed façade system uses integrated sensors and actuators that moderate their local environments through simple interactions with their immediate neighbors. Computational techniques coupled to manufacturing methods and material logics create an integral design framework leading to heterogeneous environmental and structural conditions, producing local responses to environmental stimuli, and ultimately, effective performance of the whole system.

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

summary The paper has two targets: a theoretical and a practical one which are totally dependant on each other: Its first purpose is to prove based on detailed comparative study by use of competent software apparatus that rotation in a building abiding by strict rules of adaptation to environmental changes (climate, season, time of day, sun duration etc.) should be viewed by modern architecture as a sine-qua-non in terms of energy consumption economy, environmental resources protection, achievement of high standards of living in the city. The aforementioned benefits will be evidenced by means of comparison of responsive structures to traditional ones. The second and most important purpose is to elaborate and provide the fundamental data and information for the creation of a supporting software for the above described model. The two in interaction will result in “revolution” in modern architecture.

title Applying augmented reality for data interaction and collaboration in BIM

summary Building Information Modelling (BIM) is expected to enable efficient collaboration, improved data integrity, distributed and flexible data sharing, intelligent documentation, and high-quality outcome, through enhanced performance analysis, and expedited multi-disciplinary planning and coordination. Despite these apparent benefits, the collaboration across the architecture, engineering and construction (AEC) disciplines is largely based on the exchange of 2D drawings. This paper reports the findings from a research project that aims at developing measures to enhance BIM-based collaboration in the AEC industry. Based on focus group interviews with industry participants and case studies of BIM applications, visualisation was identified as an interactive platform across the design and non-design disciplines. It is argued that visualisation can enhance the motivation for BIM-based collaboration through integration of advanced visualisation techniques such as virtual reality (VR) and augmented reality (AR). An AR interface for a BIM server is also presented and discussed in the paper. AR can open up potential opportunities for exploring alternatives to data representation, organisation and interaction, supporting seamless collaboration in BIM.

summary This work documents the implications of using physical media to teach digital design concepts, techniques, values and approaches. With the pedagogy and work of a seminar and studio across two Universities as test cases, this research seeks to prove that a parametric and algorithmic approach to architecture is most fruitfully understood as the connection between logic, mathematics and aesthetics. Students trace the indirect relationships between process and product so as to enable the application of these connections in a non-linear, exploratory and goal-flexible design process. The first phase of student work involves the creation of an image, constructed with ink or graphite on paper, that embodies a parametric aesthetic. Students are tasked articulating and performing operations, such as dividing a curve, packing shapes, and conditional transformations. Subsequently, students fabricate a surface-conscious model with modules that have the capacity to vary based on their grid parameter, using historically rooted techniques such as weaving, perforating, layering and tessellation. Digital fabrication and parametric modeling is then introduced, not as a means to a predefined end, but as another medium, capable of participating with manual techniques. As an example, a fabricated paper-based installation is generated with parametrically generating a cut-sheet, partially blind to its assembled manifestation. The hypothesis of this research is tested in more comprehensive projects that follow as environmental forces are resolved through dynamic and ambiguous visual and spatial conditions.

doi https://doi.org/10.52842/conf.caadria.2010.117
summary Programming takes designers away from typical domain- and task-based interfaces such as three-dimensional modellers. It thus imposes additional cognitive load on the already challenging design task. Programming in the model is a system design strategy that embeds the act of programming in a 3D CAD model. This paper presents the argument for programming in the model and two user interface constructs that support such programming.

summary The instrumental and aesthetic implications of architecture’s engagement with science and technology has a long history, part of which includes the period following the Second World War when the rapid technological advances of the Industrial Revolution merged with a general cultural mindset characterized by themes of progress and futurism. For postwar thinkers like Reyner Banham, this interest in a futurist architecture suggested an approach to design rooted less in architectural precedent than technological extrapolation. While a precedent based approach might be viewed as more disciplinary in nature, technological extrapolation suggests an inclination towards interdisciplinarity. Thus, Banham’s concept of extrapolation encouraged architects to look beyond the limits of their own discipline as a means of discovering new forms of knowledge and expertise. Indeed Banham was engaged in taking stock of the technological advances particular to his time while simultaneously anticipating the implication of these advancements for the future. To this extent, the postwar period and its inherent futurism provides a useful and poignant lens through which to take stock of our own technological climate. Given the equally revolutionary advances in computer technology in the last twenty years, our contemporary moment can be seen as having many parallels with the postwar period, and not unlike the postwar generation of architects and thinkers, contemporary designers are inevitably faced with the challenge of engaging new technological advances and their implications for architecture. In our current age of digital and biological technologies, these advances are both rapid and widespread, and include LED and fiber-optic lighting systems, motion sensing, interface design, solar tracking photovoltaic skins and wind harnessing technologies, magnetic levitation, and robotics. This paper begins with an examination of design work and criticism from the postwar period and proceeds to utilize that examination as an historical framework for addressing issues of contemporary design and 21st Century technological advancement.

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’s 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.

title Situated Bioclimatic Information Design: a new approach to the processing and visualization of climate data
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 Information dependencies between architects and services engineers for early design evaluation: a framework for an energy design tool for architects
source Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 313-222

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.
