title	Adaptation as a Framework for Reconsidering High-Performance Residential Design: A Case Study
source	ACADIA 13: Adaptive Architecture [Proceedings of the 33rd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-926724-22-5] Cambridge 24-26 October, 2013), pp. 109-118

summary	This paper outlines an approach to adaptive residential design explored through recent research and an executed prototype, the North House project (2007-2009), undertaken through an interdisciplinary collaboration of researchers and students from the University of Waterloo, Ryerson University and Simon Fraser University in concert with professional and industry partners. This project aimed to develop a framework for the delivery of adaptive detached residential buildings capable of net-zero energy performance in the temperate climate zone, or the near north. Within this project, the term “adaptive” is developed across several tracts of conceptualization and execution including site and climatically derived models for building material composition and envelope ratios, environmentally-responsive kinetic envelope components, intelligent HVAC controls and interactive interface design aimed at producing co-evolutionary behaviors between building systems and inhabitants. A provisional definition of adaptive architecture is outlined to address this range of considerations that calls into question the stable image of domestic architecture and its relationship to energy and contemporary assumptions regarding sustainable design. This paper also outlines computational approaches to design optimization, distributed building systems integration and the human-controls interfaces applicable to the home’s ecology of physical and information technologies.

title	From No-Dimensions to N-Dimensions with Parametric Point-Clouds
source	International Journal of Architectural Computing vol. 5 - no. 1, pp. 46-59
summary	This paper presents an innovative approach towards parametric design using point-clouds as design media. Exposing the internal numeric representation of digital models led to the development of parametric point-clouds as design drivers. A parametric point-cloud concept is presented in this paper, exploring its potential application for behavior modeling, generative design and performance-driven design of building envelopes.

title	Illumination of urban space using digital simulation methods: Exemplified on the UNESCO World Heritage Site of Bamberg
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 127-140
summary	The photorealistic visualisation of lighting-scenarios with the help of virtual 3d city models is gaining importance as a tool, helping to make decisions in the process of planning. This form of presentation makes sense to every spectator very quickly and in a definite way, thus it makes collaboration easy especially in interdisciplinary planning teams. Moreover the light-planner has the possibility to check his design in a virtual surrounding and therefore gain additional reliability for his planning. The displayed, exemplary, workflow and the techniques belonging to it, allow to show situations during the course of planning and to present the current state of planning realistically. Hence the quality of planning can be enduringly improved, through experimental use of new materials and ideas. Moreover alternative planning that does not show the right results can be eliminated very early in planning process, with not need for special investments to do so.

title	Body\|Form\|Space: Geometric translations of the body in motion
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 431-438
summary	This paper presents a novel approach to digital investigation of body, space, form and motion to expose issues of spatial perception. The spatial experience as generated from, and translated by, the human body is the focus of this work. The work explores the representational value of the body’s sense-image, the context and spatial/visual literacy of the learned sense of space-time generated from the study of the human body. Here the body is conceived not just in space but also in time, affording the ability to reinterpret the body and it’s dynamic motion engaged not as a static condition, but as a set of event spaces. Motion here is defined as a multiplicity of continuities that can be subdivided by artificial boundaries that describe space, time and body. The study of a series of bodies and movements is described that explore the human condition as a series of differential lines (form + time) and framed structures (bodies + motion). The intention is to examine the relationship between human form and metaphysical simultaneity as generators of architectural form. The work is structured by a research approach that dissects and isolates the representational concept/image from the body in a way that might offer an alternative description to the traditional historic models.

summary	Differences in the preferred modes of representation of architects and their clients create challenges to their collaboration in the design process. Traditional two-dimensional drawings such as plans, sections and elevations form the backbone of architectural representation, anchoring text labels to record relevant non-graphical information. Nominally geometric “slices” through the proposed building volume, these drawings employ abstractions and conventions unique to professional practice. In contrast, non-architects think about building configuration largely through experiential or photographic perspective. This challenge increases over the life of the project. Simple drawings, such as those used in schematic design, are easily understood by all parties. However, as the building design develops the architects encode more and more design detail through the drawing conventions of construction documents, inadvertently making this detail less and less accessible to non-architects. We present DVIN, a prototype system that uses coordinated plan and perspective views for navigation of building information models, linking the information to an individual’s spatial navigation skills rather than their document navigation skills. This web-based application was developed using Java and VRML. The prototype makes it easier for naive users to locate and query building information, whether they are a client, a facility manager, or possibly an emergency responder. * NOTE: two pages missing from the printed proceedings have been appended to the PDF version of this paper and numbered 'erratum page 1' and 'erratum page 2' *

summary	This paper sets out an approach to urban modelling derived from early work with cellular automata and agglomeration models. In these cases the models are an example of distributed representation, where the rules built in to the model are replicated in all the discrete components of the model be they cells or agents. This is the classic AI. / AL paradigm of emergent systems. The paper describes the main structure of the models, and presents examples of the use of this modelling process in design education, pointing out the way dynamic models allow mapping on to interesting speculations about the dynamic of the city, and its social systems. The paper ends with a report on the use of such models as a design decision support system and how they will be used in planned work in master planning in the London Thames gateway area under the UK govt. sustainable communities initiative.

title	Constraint-Based Design in Participatory Housing Planning
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 687-694

summary	The research presented in this paper deals with the yet unexplored development of a constraint-based design strategy to support participatory housing planning processes in Latin America. The article discusses the implementation criteria of a constraint satisfaction approach to solving the building bulk design problem. This elementary problem to the architecture practice, is concerned with the synthesis of the boundary geometry from the volume, shape and allocation of the building and any part thereof located inside a given zoning lot. A legal solution to a building bulk design problem is a building cubature that complies with all the applicable bulk regulations. The case study applies to the common class of single-family house units produced in Chile and the regulatory framework implemented there. Two different computer implementation criteria are being tested in an ongoing series of trials. The first, and most extensively developed, makes use of Maxon’s XPresso® visual scripting environment to set up a semi-automated controllable design environment that allows to create parametric feature-based 3D models of building bulk solutions. The second approach is currently being tested by using Ilog’s OPL Studio® constraint programming environment to achieve fully automated search and 2D graphic visualization of the complete set of solutions to separate subdomains of the bulk problem.

source	SIGraDi 2007 - [Proceedings of the 11th Iberoamerican Congress of Digital Graphics] México D.F. - México 23-25 October 2007, pp. 418-422
summary	This study assesses an innovative immersive sketching and model making system: the Hybrid Ideation Space (HIS). The system enables designers to sketch and make models all around them in real-time and real scale using a digital tablet (sketches), image capture (physical models) and a spherical projection device (immersion). We carried out an experiment to evaluate this system using the concept of Design Flow and workload with industrial design students working in teams during the ideation stage of the design of a car. The HIS was compared to analog tools and hybrid techniques.

title	Detailed 3D Modelling of Castles
source	International Journal of Architectural Computing vol. 5 - no. 2, pp. 200-220
summary	Digitally documenting complex heritage sites such as castles is a desirable yet difficult task with no established framework. Although 3D digitizing and modelling with laser scanners, Photogrammetry, and computer aided architectural design (CAAD) are maturing, each alone is inadequate to model an entire castle in details. We present a sequential approach that combines multiple techniques, each where best suited, to capture and model the fine geometric detail of castles. We provide new contributions in several areas: an effective workflow for castle 3D modelling, increasing the level of automation and the seamless integration of models created independently from different data sets. We tested the approach on various castles in Northern Italy and the results demonstrated that it is effective, accurate, and creates highly detailed models suitable for interactive visualization. It is also equally applicable to other types of large complex architectures.

title	Road hierarchy and speed limits in Brasília/Brazil
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary	This paper aims at exploring the theory of the Social Logic of Space or Space Syntax as a strategy to define parameters of road hierarchy and, if this use is found possible, to establish maximum speeds allowed in the transportation system of Brasília, the capital city of Brazil. Space Syntax – a theory developed by Hillier and Hanson (1984) – incorporates the space topological relationships, considering the city shape and its influence in the distribution of movements within the space. The theory’s axiality method – used in this study – analyses the accessibility to the street network relationships, by means of the system’s integration, one of its explicative variables in terms of copresence, or potential co-existence between the through-passing movements of people and vehicles (Hillier, 1996). One of the most used concepts of Space Syntax in the integration, which represents the potential flow generation in the road axes and is the focus of this paper. It is believed there is a strong correlation between urban space-form configuration and the way flows and movements are distributed in the city, considering nodes articulations and the topological location of segments and streets in the grid (Holanda, 2002; Medeiros, 2006). For urban transportation studies, traffic-related problems are often investigated and simulated by assignment models – well-established in traffic studies. Space Syntax, on the other hand, is a tool with few applications in transport (Barros, 2006; Barros et al, 2007), an area where configurational models are considered to present inconsistencies when used in transportation (cf. Cybis et al, 1996). Although this is true in some cases, it should not be generalized. Therefore, in order to simulate and evaluate Space Syntax for the traffic approach, the city of Brasília was used as a case study. The reason for the choice was the fact the capital of Brazil is a masterpiece of modern urban design and presents a unique urban layout based on an axial grid system considering several express and arterial long roads, each one with 3 to 6 lanes,

summary	The use of Internet communication technologies in distributed teams has been carried out for well over 10 years. In this time, various methods to communicate and transfer information have been developed. A large amount of effort has been placed on enabling normal conversation to take place and it could be said, that with technologies like Skype, this is established. This enables planning partners to discuss, but we still need to convey what they are discussing. In short, the contents are still lacking. Technologies exist to allow users to share files or images, however this does not nearly reach the intensity or quality of discussions when partners are sitting together in front of a drawing or model. At best, screen sharing allows participants to see the same image but with low resolution and bad system response. The goal of the project is to allow distributed team members to discuss design issues with a common 3D model where participants can manipulate the model together in real time.. The speed of the system is also buttressed by the simplicity of the application: as a Java applet, it is possible to start the Intervision3D system in any browser or as a separate applet on any system. Files can be imported and then rendered using the JOGL Engine (Java Bindings for Open GL). JOGL allows the full Open GL suite to be used in rendering the model including lighting and textures: even normal PCs can do this quite well. The first implementation of the system is within an existing internet-based Design Studio and the paper elucidates how the first uses of the system have (partially) helped to increase the exchange of design ideas over the Internet.

doi	https://doi.org/10.52842/conf.caadria.2009.277
summary	Prototype manufacturing as an educational tool has been very successful at the college level in architecture and engineering design. This paper discusses an innovative inquiry-based learning approach rather than the problem-based learning models commonly utilized by other similar programs. For example, several research-funded technology projects (e.g., Cappelleri et al. 2007) look at involving students in problembased learning exercises (e.g., building robots); however, these exercises (while providing valuable experiences) have predetermined outcomes ingrained by the teachers, the project structure, and the components used to construct the devices. Therefore, inquisitive and creative problem solving is limited to the “kit-of-parts” in their approach to solving the problem. The inquiry-based CADCAM pedagogy model is more concerned with the process of solving a problem through the vehicle of prototyping than with the specificity of the design project itself. This approach has great potential. First, the need to solve the problem drives learning on multiple levels, integrating interdisciplinary ideas into the problem and solution. Second, the problem interlocks disciplines through inquiry knowledge building in team exercises. Finally, it encourages diversity and flexibility by allowing students to look at problems from multiples perspectives and points of view.

title	Teaching Digital Design Exploration: Form Follows
source	International Journal of Architectural Computing vol. 5 - no. 4, pp. 685-702
summary	This paper presents some challenges of teaching computational geometry to architectural students, and proposes a multi-level pedagogical scheme introducing associative geometry and parametric modeling/design into architectural design education. It reports on two pedagogical experiences: one held in the context of a spatial geometry course in the first year of education; and another one, in a digital design studio with third-year architectural students. More specifically, it discusses the impact on design exploration of a library of interactive referents models introduced into the architectural studio. Situated in the 'performance' paradigm of digital design methods, they allow for design object explorations based on modification of architecturally meaningful features (structural, environmental, functional, etc.). The form of a design object can thus 'follow' function, structure, or even sustainability. The digital methods and the design knowledge transferred by the interactive models, together with their visual nature, are found to amplify the processes of 'seeing-as' and the 'reflective conversation with the situation' considered essential for creative design.

title	Is a Digital Model Worth a Thousand Pictures?

summary	This communication addresses the use of a new type of referents database in the context of an architectural design studio. It discusses the results of design experiences held with the objective to study the cognitive effects of a teaching approach based on precedents and metaphors available as interactive and reusable digital models to students. The introduction of this referent-based approach is inspired by three major principles: the largely accepted fact that the creative work of architects is highly supported by referring to precedents and metaphors; the use of algorithmic digital methods to encapsulate architectural knowledge; and the constructivist approach to architectural design education. The study finds that the role of the modeled referents is helpful for the design studio learning, and that they are most creatively used when internalized by the student.

summary	The gaming industry plays a pivotal role in creating real-time advanced shaders nowadays. With better and more affordable computer hardware, shaders are beginning to be used in other non- gaming softwares. The virtual reality visualization tools used by the architectural designers can benefit from this. This paper investigates the impact of real-time shaders on the performance of architectural virtual reality visualization of 3D models and provides a guide for architectural users to decide the optimal number of shaders to use based on the size of the model.

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	Preservation of existing buildings through methods of Operations Research
source	DACH 2007, International Conference on Digital Applications in Cultural Heritage, P. 157-175
summary	The revitalization of existing buildings is getting more and more important. We are facing a situation where in many cases there is no need to design new buildings because an increasing number of existing buildings is not used anymore. The most ecological procedure to revitalize these buildings would be through a continuous usage and by making few or no alterations to the stock. Thus, the modus operandi could be named a “non-destructive” approach. From the architects’ point of view, non-destructive redesign of existing buildings is time-consuming and complex. The methodology we developed to aid architects in solving such tasks is based on exchanging or swapping utilization of specific rooms to converge in a design solution. In this regard, it was examined whether solutions for reuse tasks can be produced automatically by the use of optimization processes in floor plan design. These solutions shall be produced by swapping of existing areas. The objective is to obtain feasible planning solutions by means of these computer-based processes, which will serve the architect as a basis for the further editing of the plans. The methodical basis for this procedure is formed by models from Operations Research. The design of the model developed relates to problems in logistics, for example, the loading in trans-shipment centers. It also has analogies to board games like Chess or Go. These games are based on a specific number of fields or crosses of grid lines which are occupied by various tokens. Occupation is subject to a variety of conditions or rules. Compliance to conditions and objectives is clearly defined by the use of these rules. The analogy to our model is the fixed grid, the limited possibility to occupy fields and the fulfillment of an overall goal, i.e., to win the game. Therefore the model does not alter geometric proportions or locations of rooms but changes their occupancy such that a new usage could be applied to the building.

summary	The aim of this research project is to develop a methodological process that allows the designer to assemble and create various scenarios representing an urban environment through the utilization of economical computer based methods. During the last decade different techniques have been developed to address the needs of visualisation of urban areas many being based on photographic and photogrammetric systems. The demand for 3-D urban models continues to grow and although new technologies have undoubtedly reduced the time needed for the construction of a 3D model, there are still some remaining problems related to data quality and the level of the dimensional accuracy. On the basis that these problems are primarily related to software and hardware constraints and in conjunction with the fact that the richness and complexity of an urban space is difficult to represent in a 3D context, there is a growing interest in the modelling of the urban fabric which is not dependant on heavily capitalised technology for its data. The core principle of the current research project is summarised in the process of deploying a mechanism, which will allow the visualisation of urban form without loosing its quality and architectural characterisation. This technique suggests that a selection of various building types can be collected and described by their architectural elements, textures, scale and dimensions. From each group of buildings a library of fragmented architectural components can be then derived. The accomplishment of this methodology is the formulation of a 'grammar' comprised of a characteristic ‘syntax’ and its associated ‘vocabulary’. Therefore the expected outcome of this research is an approach that would allow the designer to create easily and quickly not only any desired building but additionally any imaginary cityscape.

title	Computational Morphogenesis: Integral Form Generation and Materialization Processes

summary	Natural morphogenesis, the process of evolutionary development and growth, derives polymorphic systems that obtain their complex form, organisation and versatility from the interaction of system intrinsic material capacities and external environmental influences and forces. One striking aspect of natural morphogenesis is that formation and materialisation processes are always inherently and inseparably related. In stark contrast to these integral development processes of material form, architecture as a material practice is mainly based on design approaches that are characterised by a hierarchical relationship that prioritises the definition and generation of form over its subsequent materialisation. This paper will present an alternative approach to design that entails unfolding morphological complexity and performative capacity without differentiating between form generation and materialisation processes. Based on an understanding of material systems not as derivatives of standardized building systems and elements but rather as generative drivers in the design process this approach seeks to develop and employ computational techniques and digital fabrication technologies to unfold innate material capacity and specific latent gestalt. Extending the concept of material systems by embedding their material characteristics, geometric behaviour, manufacturing constraints and assembly logics within integral computational models promotes an understanding of form, material and structure not as separate elements, but rather as complex interrelations in polymorphic systems resulting from the response to varied input and environmental influences and derived through the logics and constraints of advanced manufacturing processes. These processes will be explained along 8 research projects.
