title	Collaborative Parametric BIM
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. 127-134
summary	The paper will be focussing on a number of digital design tools used in [our groups credentials]. A new laboratory called […] is developed with Virtual Reality for collaborative architectural design. A brief description of the systems and how they are used to support a design team is given. Synchronic and a-synchronic, local and inter-local communication is made possible. Methods for introducing sustainability in the digital design process and user participation over the Internet will be discussed. The results of the author’s PhD research “Collaborative architectural design in virtual reality” are used to develop a new approach in which team members use their own specific software. Swarm design applications developed in Virtools are used at the start of a project. The objects in the swarm can be urban and architectural functional volumes. Examples of the first are houses, offices, factories, roads and water ways. Examples of the second are working, dining, shopping and waiting spaces. Relations between the functional volumes with or without constraints make the functional volumes swarm to find equilibrium. Everything is dynamic, meaning that relations and functional volumes can change any time. Alternatives can be developed using different values for these parameters and by top-down intervention. When the final global layout has been chosen, using a criteria matrix with sustainability criteria to be judged by all participants, including the future users, a next phase is started amongst professionals using parametric design software. A study into different types of parametric design software makes clear why object parametric software can be used for IFC based BIM, while the more interesting process parametric software can not. To make this clear a pragmatic description of the IFC format is given with a simple example of such a file. Future research will be proposed in which applications of different disciplines are connected through the application programming interfaces, while integrating as much as possible the building information and knowledge in the IFC format.

source	FUTURE CITIES [28th eCAADe Conference Proceedings / ISBN 978-0-9541183-9-6] ETH Zurich (Switzerland) 15-18 September 2010, pp.115-124
summary	This paper describes a teaching experience conducted and carried out as part of the architectural coursework of the first year students. The workshop is the first of three planned to take place during the course of the first year studio. It aims at introducing new ways of thinking as well as introducing students to the new pattern of architectural education; It also helps communicating and-if required- unlearning accumulative conceptions that were unconsciously gained by the lack of practice, ignorance of actuality or simply by the accumulation of images and ideas in their minds over the years. A grammatical approach was chosen to develop the described methodology, based on the shape grammars system in general, and on one of its basic skills of seeing/understanding shapes & extracting elements of the visual composition in particular

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 ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô 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‚Äôs 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.

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. 103-109
summary	In this work, we address the challenges in the realization of free-form architecture and complex shapes in general with the technical advantages of ruled surfaces. We propose a geometry processing framework to approximate (rationalize) a given shape by one or multiple strips of ruled surfaces. We discuss techniques to achieve an overall smooth surface and develop a parametric model for the generation of curvature continuous surfaces composed of ruled surface strips. We illustrate the usability of the proposed process at hand of several projects, where the pipeline has been applied to compute NC data for mould production and to rationalize large parts of free-form facades.

title	[make]SHIFT: Information Exchange and Collaborative Design Workflows
doi	https://doi.org/10.52842/conf.acadia.2010.139
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. 139-144
summary	This paper explores design processes requiring the invention and implementation of customized workflows for the optimization of design information exchange. Standard workflows in design software are typically dependent upon the use of proprietary file formats to communicate design intent across the design team. Software platforms promote “one-stop-shop” proprietary approaches to BIM where all team members and consultants ideally operate within a single model environment and store information within a single file format. While the ‘single model’ approach can be effective under some circumstances, this approach is often found to be limiting when the design process calls for the integration of other design toolsets and delivery processes. This is especially true for large complex projects where multiple participants with different software requirements need to collaborate on the same design. In these cases, various non-standard ways of working are often implemented, resulting in a new means of communicating design and building information across a team. This paper will outline the impact customized workflows have on the design process at NBBJ and evaluate their potential for leading to more innovative design and integrated teams. The first study will explore and evaluate the communication and collaborative process that took place in the design development and construction documentation stages of the Hangzhou Stadium. The second study will be an overview of ongoing investigation and experimentation into customized workflows for team and data integration.

summary	The possibility of including information and communication technologies (ICTs) to support teaching and learning project has been explored from different perspectives by researchers. This study intends to contribute to the establishment of reference for the construction of a new paradigm concerning the methodology for teaching of projects that are supported by free platforms. This research attempts to identify opportunities for simulation, interaction and collaboration that are provided by free platforms. The analysis of the results indicates that the possibility of interaction, collaboration and simulation that ICTs offer act as a support for the methodology of teaching/learning projects.

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.

summary	The following paper deals with a performance-driven morphogenetic design task to improve the conditions of room acoustics, using as a case study the material laboratory of the School of Architecture at Federico Santa Maria University of Technology. Combining contemporary Parametric Modeling techniques and a Performance- Based approach, an automatic generative system was produced. This system generated a modular acoustic ceiling based on Helmholtz Resonators. To satisfy sound absorption requirements, acoustic knowledge was embedded within the system. It iterates through a series of design sub-tasks from Acoustic Simulation to Digital Fabrication, searching for a suitable design solution. The internal algorithmic complexity of the design process has been explored through this case study. Although it is focused on an acoustic component, the proposed design methodology can influence other experiences in Parametric Design.

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	Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 247-264.
summary	The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called ‚Äúgingerbread houses‚Äù, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

summary	Didactic material in digital format is being produced in different contexts focused on similar themes. The efforts of such production are not being optimized. This paper describes the structuring process of a system of collaborative production of didactic material aimed at broadening geometric vocabulary and repertory in architecture. Established material regarding this theme is analyzed through the concept of learning objects. Efforts concentrate on the establishment of a taxonomy to characterize these objects, seeking to make the search and selective recovery of these objects easier. An environment has been made available for sharing, discussion and validation of this material, outlining a methodology for the establishment of the proposed system.

title	Authoring Tools for KOC - Concepts and Pedagogical Use
source	International Journal of Architectural Computing vol. 8 - no. 2, 183-200
summary	One of the main problems of teachers aiming to teach the construction techniques used in to build a building is the lack of practical examples to show to their students. In order to be useful, these examples must come from real projects or even better the teachers may take their students to constructions sites, but this latter option is not always available and may be dangerous. To deal with this problem, Los Andes University has committed the construction of a knowledge repository containing information gathered from real projects and semantically described, in order to provide easy access to its content and in the language of people of construction. This project is called KOC, standing for Knowledge Objects of Construction, which uses an ontology to describe semantically the data contained in the repository. Being the pedagogical objective of the project, it is important to provide the teachers with additional tools to generate new knowledge objects, based on existing knowledge objects in the repository. This paper presents three composition tools for KOC: a complex objects composer issued from structured searches, a constructive processes composer and a case study composer, all of them aiming the improvement of learning quality in the technical area of building construction at the architecture and engineering schools. The paper also shows some examples of knowledge objects and how KOC is been used in the courses of the Architecture Department of Los Andes.

title	Information Controlled Erosion
doi	https://doi.org/10.52842/conf.acadia.2010.145
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. 145-150
summary	This paper documents research of a design process that interrelates a single information model to 5-axis, waterjet cutting technology. With the intention of creating an optimized design, data is streamed through a building information model that controls geometry parametrically by a component/system relationship. At the scale of a 4’x8’ panel, material properties and pattern variability act as underlying initiators of design rather than post-rational information. In a manner uncommon to the discipline, the information model is being used as a generative tool, rather than as one for mere documentation. The research assigns a limestone wall type to the panel—a material predominantly used in areas where it is indigenous and typically desirable for its texture, color, and thermal properties. The intention is to develop potentialities through material specificity in the information model’s conceptualization. The water-jet process is then used to erode the limestone to achieve varying fields of scalar voids. In addition, the thickness of wall cladding attenuates for figuration and interest. The final stone panels transition from a rain screen system to a solar screen that modulates light, thereby linking environmental intentions to current technological capabilities. The information model is exported for analysis of daylight and structural dynamic qualities and quantities as part of the workflow. Parameters within the information model database facilitate a dimensionally controlled iterative process. Moreover, fabricating with building materials via the information model expedites a design and makes possible for materiality to move beyond merely conceptual representation.

source	SIGraDi 2010_Proceedings of the 14th Congress of the Iberoamerican Society of Digital Graphics, pp. Bogotá, Colombia, November 17-19, 2010, pp. 218-221
summary	Currently almost all complex products, including physical products as well as information - based products are developed through the interaction of many participants that work on different elements of project. This creates a need for increased adoption of information technology and computer - based communication tools to manage the entire process of product development. This work proposes a framework of a collaborative system to support conceptual design. This should provide a team environment in which to discuss, exchange knowledge and information, negotiate, and develop joint projects through intelligent interfaces in order to have more flexibility to design more efficiently and effectively.

title	Local Code: The Critical Use of Geographic Information Systems in Parametric Urban Design
doi	https://doi.org/10.52842/conf.acadia.2010.234
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. 234-242
summary	Local Code uses geospatial analysis to identify thousands of publicly owned abandoned sites in major US cities, imagining this distributed, vacant landscape as a new urban system. Deploying GIS analysis in conjunction with parametric design software, a landscape proposal for each site is tailored to local conditions, optimizing thermal and hydrological performance to enhance local performance and enhance the whole city’s ecology. Relieving burdens on existing infrastructure, such a digitally mediated, dispersed system provides important opportunities for urban resilience and transformation. In a case study of San Francisco, the projects’ quantifiable effects on energy usage and stormwater remediation would eradicate 88-96% of the need for more expensive, centralized, sewer, and electrical upgrades. As a final, essential layer, the project proposes digital citizen participation to conceive a new, more public infrastructure as well.

summary	The historical centre of the village of Castelnuovo (located in Abruzzo, a region in central of Italy) was seriously damaged by the earthquake of the 6th of April 2009. Following the survey by the Civil Protection, all dwellings have been classified as unsuitable for habitation. The village should be either abandoned or totally rebuilt. But which is its value? Is there something worth of being preserved? If observed from a biodiversity point of view, or more precisely from a “cultural biodiversity” point of view, the historical centre possess interesting materials and immaterial characteristics. These qualities constitute real guidelines for a possible recovery project. Since there is not any possibility to make a survey of the inner village because of its destruction by the earthquake, in this research we have decided to use information technology, in order to rebuilt it and study it in a three-dimensional environment. In this paper we describe the theoretical basis, the method of elaboration and the instruments we have used to locate and evaluate the memories that should be preserved in a new project. Starting with a traditional documentation, such as photographs and drawings, we have used a variety of software (graphics editing program, CAD, 3D modeler, videogame 3D-engine), because of the several hypothesis considered.

summary	Digital Fabrication and Hybrid Interface: Lessons in Agriculture :abstract Two vitally important fields of work in architecture and computing—in digital fabrication methods and in the development of interfaces between digital and analog systems—can find new forms in their combination with one another. Moreover, a recent such experiment in the production of landscape rather than building not only suggests a number of implications for architectural work, but of ecological, economic and urban structures that underlie the projects’s visible formal and aesthetic orders. This project, “Hyperculture: Earth as Interface,” studied the potential outcomes of modifying a commonly employed information infrastructure for the optimization of agricultural production throughout most of America’s heartland; and that same infrastructure’s latent flexibility to operate in both “read” and “write” modes, as a means for collaborative input and diversified, shared output. In the context of industrialized agriculture, this work not only negotiates seemingly contradictory demands with diametrically opposed ecological and social outcomes; but also shows the fabrication of landscape as suggestive of other, more architectural applications in the built environment. The Hyperculture project is sited within several contexts: industrial, geographically local, ecological, and within the digital protocols of landscape processing known as “precision agriculture.” Today, these typically work together toward the surprising result of unvariegated repetition, known commonly as monoculture. After decades of monoculture’s proliferation, its numerous inefficiencies have come under broad recent scrutiny, leading to diverse thinking on ways to redress seemingly conflicting demands such as industry’s reliance on mass-production and automation; the demand for variety or customization in consumer markets; and even regulatory inquiries into the ecological and zoning harms brought by undiversified land use. Monoculture, in short, is proving unsustainable from economic, environmental, and even aesthetic and zoning standpoints. But its handling in digital interfaces, remote sensing and algorithmically directed fabrication is not.

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?

summary	This paper presents an application of swarm intelligence towards the problem of spatial configuration. The methodology classifies activities as discrete entities, which self-organise topologically through associational parameters: an investigation of emergent route formation and spatial connectivity based on simple agent and pheromone interaction, coupled with the problem of ‘loose’ rectangular geometric assembly. A concept model sniffingSpace (Ireland, 2009) developed in Netlogo (Willensky, 1999), which established the self-organising topological capacity of the system, is extended in Processing (Fry & Rea, 2009) to incorporate rectangular geometry towards the problem of planning architectural space.

title	The Chair Back Experiment: Hierarchical Temporal Memory and the Evolution of Artificial Intelligence in Architecture
source	International Journal of Architectural Computing vol. 8 - no. 2, 151-164
summary	Computational synthesis tools that automatically generate solutions to design problems are not widely used in architectural practice despite many years of research. This deficiency can be attributed, in part, to the difficulty of constructing robust building specific databases. New advances in artificial intelligence such as Hierarchical Temporal Memory (HTM) have the potential to make the construction of these databases more realistic in the near future. Based on an emerging theory of human neurological function, HTMs excel at ambiguous pattern recognition. This paper includes a first experiment using HTMs for learning and recognizing patterns in the form of visual style characteristics in three distinct chair back types. Results from the experiment indicate that HTMs develop a similar storage of quality to humans and are therefore a promising option for capturing multi-modal information in future design automation efforts.
