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.

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

summary Increasingly, digital architectural data will become available through information technology. Yet until now, there were no satisfying methods to query this data for architectural purposes. This paper introduces an information retrieval system for parcels that not only allows searching for specific attributes, but also includes properties of shape and context of the building plots. An automatically generated index stores the relevant spatial properties as normalized bitmap images on several layers. When a query is started, only this index has to be queried and not the complete database. The search process can be controlled through a graphical interface that incorporates the user’s sketches. The retrieved parcels are presented as a sorted list of vector drawings including their contained buildings. With the simplified access to these case-studies, quality and efficiency of the architectural design process could be increased.

title Generative Design and the Reduction of Presence
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. 97-106
summary Digital design/fabrication is slowly emancipating architectural design from its traditional static/representational role and endowing it instead with a new, generative function. In opposition to the classical isomorphism between drawings and buildings, wherein the second stand as translations of the first, the digital design/fabrication scenario does not strictly fall within a semiotic frame as much as within a quasi biological context, reminiscent of the Aristotelian notion of entelechy. For the digital data does not represent the building as much it actively works to become the building itself. Only upon sending a given file to a machine does the building begin to materialize as an empirical reality, And eventually a habitable space as we empirically know it. And until the digital data actualizes itself, the building qua building is no more than one single, potential possibility among many others. This new universe of digital design/fabrication does not only cause buildings to be produced as quick, precise, multiply-generated objects but also reduces their presence as original entities. Like cars and fashion items, built structures will soon be manufactured as routinely-consumed items that would look original only through the subtle mechanisms of flexibility: frequent alteration of prototype design (Style 2010, Style 2015..) and “perpetual profiling” (mine, yours, hers,..). The generic will necessarily take over the circumstantial. But this truth will be veiled since “customized prototypes” will be produced or altered to individual or personal specifications. This implies that certain “myths” have to be generated to speed up consumption, to stimulate excessive use and to lock people into a continuous system which can generate consumption through a vocabulary of interchangeable, layered and repeatable functions. Samples of “next season’s buildings” will be displayed and disseminated to enforce this strategy of stimulating and channeling desire. A degree of manipulation is involved, and the consumer is flattered into believing that his or her own free assessment of and choice between the options on offer will lead him or her to select the product the advertiser is seeking to sell. From the standpoint of the architect as a maker, the rising upsurge of digital design and fabrication could leave us mourning the loss of what has been a personal stomping ground, namely the intensity of the directly lived experiences of design and building. The direct, sensuous contact with drawings, models and materials is now being lost to a (digital) realm whose attributes refer to physical reality only remotely. Unlike (analogue) drawings and buildings, digital manipulations and prototypes do not exercise themselves in a real space, and are not subjected in the most rigorous way to spatial information. They denote in this sense a loss of immediacy and a withering of corporal thought. This flexible production of space and the consequent loss of immediate experience from the part of the designer will be analyzed within a theoretical framework underpinned mainly by the works of Walter Benjamin. Samples of digitally-produced objects will be used to illustrate this argument.

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 Towards Changeability
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. 189-200
summary Many buildings around the world have undergone successive changes over their life cycles. Regardless of the type or size of a building there are usually requirements for change due to several unanticipated forces and emerging uncertainties that act upon them. These changes might be in the building’s spatial, structural or service systems. This can be due to changes in the needs of occupants, the market demand or technological advances. Although buildings undergo change, current design practice does not address this and buildings are still designed as if they will remain static. This paper proposes an Adaptable Buildings Design (ABD) Framework to address the issue of adaptability in building design. Using this methodology uncertainties and future changes are first identified. To increase the building’s longevity, flexibility options are embedded and design rules are formulated to trigger these options when necessary. The value of adaptability is then assessed by implementing several simulations using Real Options Analysis (ROA). To demonstrate the approach, the ABD is applied to a multi-use commercial building case study. Flexibility is embedded in the building’s design across several systems allowing it to change and evolve over time based on a set of design rules. The buildings adaptability is then assessed using ROA. Positive results demonstrate the strength of the proposed methodology in addressing future change and uncertaintie.

summary We present a simulation platform to evaluate procedurally generated 3d city models with a set of agents representing urban street actors and pedestrians towards greenhouse gas emissions from transportation. Our aim is to give architects and urban planners an empiric tool to analyze, predict and quantify traffic fluctuations over time, and define the number of occupants, individual traffic and public transport in a city. In this project we show that the allocation of functions within a city is an important factor for the appearanceof traffic. The occupant’s decisions where they want to go are defined by the allocation of functions – and the distance defines the mode of transportation. We simulate the decision processes and gain information about the path, the mode of transportation, and the emissions they produce, and individual experiences like stress and effort. The autonomous driving cars are equipped with an acceleration based emission model allowing us to evaluate the inpact of jammed streets on the emission of cars.

summary Explorations conducted in university - based design studios suggest that Building Information Modeling (BIM) technology invites the adoption of a dramatically different design process. In contrast to conventional process rooted in successive refinement of initial abstractions and dependence on tacit knowledge, the Studio 21 BIM - aided process relies upon a complete and comprehensive base case and subsequent alternative schemes that are subjected to explicit analysis to support choice of the final design. The Studio 21 process can boost the objective level of performance that is achieved. It is teachable and may be a better process for addressing 21st century imperatives.

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 A Computational Medium for the Conceptual Design of Mix-Use Projects
source CAAD - Cities - Sustainability [5th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2010 / ISBN 978-1-907349-02-7], Fez (Morocco), 19-21 October 2010, pp. 109-116
summary Mix use development is receiving wide attention for its unique sustainable benefits. Nevertheless, the planning and designing of successful mixed use projects in today's environment is a complex matrix of skill sets and necessary collaborations between various stakeholders and design professionals. From a design point of view, architects are required to manage and coordinate large information sets, which are many time at odds with one another. The expansive space of knowledge and information is at its best vague and substantially ill-structured. A situation that continues to overburden architects mental and intellectual ability to understand, address and communicate the design issue. In the face of this complex condition, designers are gravitating towards information modeling to manage and organize the expansive data. However, is becoming increasingly evident that current building information modeling applications are less suited for early design activity due to their interrupted and rigid workflows. Against this background, this paper presents a theoretical framework for a computational medium to support the designer during early phases of exploring and investigating design alternatives for mix-use projects. The focus is on the conjecture between programming and conceptual design phase; when uncertainty and ambiguity as at its maximum, and the absence of computational support continues to be the norm. It must be noted however, the aim of the medium is not to formulate or automate design answers. Rather, to support designers by augmenting and enhancing their ability to interpret, understand, and communicate the diverse and multi-faceted design issue. In literature on interpretation, Hans-Georg Gadamer explains that understanding is contingent on an act of construction. To understand something is to construct it. In light of this explanation. To help designers understand the design issue, is to help them construct it. To this end, the computational medium discussed in this paper is conceived to model (construct) the mix-use architectural program. In effect, turning it into a dynamic and interactive information model in the form of a graph (network). This is an important development because it will enable an entirely new level of interaction between the designer and the design-problem. It will allow the designer to gather, view, query and repurpose the information in novel ways. It will offer the designer a new context to foster knowledge and understanding about the ill-structured and vague design issue. Additionally, the medium would serve well to communicate and share knowledge between the various stakeholders and design professionals. Central to the discussion are two questions: First, how can architects model the design program using a graph? Second, what is the nature of the proposed computational medium; namely, its components and defining properties?

title A Framework of Haptic Design Parameters for Architects: Sensory Paradox Between Content and Representation
source Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 685-700.
summary Architects—like other designers—tend to think, know and work in a visual way. In design research, this way of knowing and working is highly valued as paramount to design expertise (Cross 1982, 2006). In case of architecture, however, it is not only a particular strength, but may as well be regarded as a serious weakness. The absence of non-visual features in traditional architectural spatial representations indicates how these are disregarded as important elements in conceiving space (Dischinger 2006). This bias towards vision, and the suppression of other senses—in the way architecture is conceived, taught and critiqued—results in a disappearance of sensory qualities (Pallasmaa 2005). Nevertheless, if architects design with more attention to non visual senses, they are able to contribute to more inclusive environments. Indeed if an environment offers a range of sensory triggers, people with different sensory capacities are able to navigate and enjoy it. Rather than implementing as many sensory triggers as possible, the intention is to make buildings and spaces accessible and enjoyable for more people, in line with the objective of inclusive design (Clarkson et al. 2007), also called Design for All or Universal Design (Ostroff 2001). Within this overall objective, the aim of our study is to develop haptic design parameters that support architects during design in paying more attention to the role of haptics, i.e. the sense of touch, in the built environment by informing them about the haptic implications of their design decisions. In the context of our study, haptic design parameters are defined as variables that can be decided upon by designers throughout the design process, and the value of which determines the haptic characteristics of the resulting design. These characteristics are based on the expertise of people who are congenitally blind, as they are more attentive to non visual information, and of professional caregivers working with them. The parameters do not intend to be prescriptive, nor to impose a particular method. Instead they seek to facilitate a more inclusive design attitude by informing designers and helping them to think differently. As the insights from the empirical studies with people born blind and caregivers have been reported elsewhere (Authors 2010), this paper starts by outlining the haptic design parameters resulting from them. Following the classification of haptics into active, dynamic and passive touch, the built environment unfolds into surfaces that can act as “movement”, “guiding” and/or “rest” plane. Furthermore design techniques are suggested to check the haptic qualities during the design process. Subsequently, the paper reports on a focus group interview/workshop with professional architects to assess the usability of the haptic design parameters for design practice. The architects were then asked to try out the parameters in the context of a concrete design project. The reactions suggest that the participating architects immediately picked up the underlying idea of the parameters, and recognized their relevance in relation to the design project at stake, but that their representation confronts us with a sensory paradox: although the parameters question the impact of the visual in architectural design, they are meant to be used by designers, who are used to think, know and work in a visual way.

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.

summary This paper illustrates responsive systems, which focus on the implementation of multi-objective adaptive design prototypes from sensored environments. The intention of the work is to investigate multi-objective criteria both as a material system and as a processing system by creating prototypes with structural integrity, where the thermal energy flow through the prototype, to be understood as a membrane, can be controlled and the visual transparency altered. The work shows performance based feedback systems and physical prototype models driven by information streaming, screening, and application.

summary U-Eco City is a research and development project initiated by the Korean government. The project’s objective is the monitoring and visualization of aggregated and real time states of various energy usages represented by location-based sensor data accrued from city to building scale. The platform’s middleware will retrieve geospatial data from a GIS database and sensor data from the individual sensory installed over the city and provide the browserbased client with the accommodated information suitable to display geolocation characteristics specific to the respective energy usage. The client will be capable of processing and displaying real time and aggregated data in different dimensions such as time, location, level of detail, mode of visualization, etc. Ultimately, this system will induce a citizen’s participation with the notion of energy saving, and be utilized as an interactive energy management system from a citizen to authorities responsible for designing or developing city infrastructure. The platform’s middleware has been developed into an operative, advanced prototype, alongside a Web-based client integrates and interfaces with the Google Earth and Google Maps plug-ins for geospatially referenced energy usage visualization and monitoring.

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 Spurring new and innovative building design will be critical to the urban energy and economic future of the nation. The operation of completed buildings account for 48% of the nation’s annual greenhouse gas emissions, and 76% of all electricity generated by U.S. power plants goes to supply the building sector. Therefore developing and applying new and innovative sustainable building design will have a measurable impact on the environment. Recent studies show sustainable building design is closely linked to system integration, where various components of a building work in confluence to produce synergetic benefits. As a result, a critical component of sustainable design involves a clear understanding of building systems operation, interaction, and the selection parameters. A consideration of suitable building systems, gauging their interaction, and proposing well integrated systems can lead to producing efficient models of sustainable buildings with minimal impact on the environment. The following paper outlines the progress on a project entitled “Building Literacy: the Integration of Building Technology and Design in Architectural Education.” The project develops a digital tool for teaching/learning architectural technology from an integrated systems perspective. The project attempts to immerse students in a simulated environment that is based on the real life practice of architecture. The project accomplishes this by harnessing the capabilities of simulation and dynamic modeling programs, as well as the state of art graphic media, to create compelling and rewarding reasons for students’ engagement in the lear ning process. The project involves a multidisciplinary team of faculty from Florida International University, University at Buffalo the State University of New York, and Iowa State University and is funded by the US Department of Education for the period of 2007-2011.

summary Recently, prototyping enabled by CNC technology has found its way into design practice where concepts can be quickly and economically tested through multiple design iterations that closely approximate the realities of oneto- one construction. This has lead to the promise of renewed research in tectonics and constructional techniques where the traditional concepts of craft and the joint, that were once married to the hand, can be rediscovered through the agency of mass customization. If we apply the lineage of the trait—a representational and cognitive tool to marry complex form with the exigencies of construction—pedagogical approaches can be developed that extend the current interest in intricate surface, structural morphology and geometry towards a robust materiality rooted in componentry, the joint, and part-to-whole relationships. This paper will introduce several threads from the twentieth century that have informed these tendencies in contemporary design practice, emerging from the well spring of Viollet-le-Duc. The thesis is supported by undergraduate model-based research employing digital design and fabrication techniques.

title Patterns, heuristics for architectural design support: making use of evolutionary modelling in design

summary Software used by architectural and industrial designers has shifted from becoming a tool for drafting, towards use in verification, simulation, project management and remote project sharing. In more advanced models, design parameters for the designed object can be adjusted so that a family of variations can be produced rapidly. With the advances in computer aided design (CAD) technology, design options can now be generated and analyzed in real time. However the use of digital tools to support design as an activity is still at an early stage and has largely been limited in functionality with regard to the design process. To date, major CAD vendors have not developed an integrated tool that is able to leverage specialised design knowledge from various discipline domains (known as expert knowledge systems) as well as to support the creation of design alternatives that satisfy different forms of constraints. We propose that evolutionary computing and machine learning be linked with parametric design techniques in order to monitor a designer’s cognition and intent based on their design history. This will lead to results that impact future work on design support systems which are capable of supporting implicit constraint and problem definition for wicked problems that are difficult to quantify.

summary This paper presents an assessment of a selection software tools for urban design confronting their capabilities with the goals of the CityInduction research project. The goal of this paper is the assessment of existing platforms for computer aided urban design to select one as the basis for implementing the urban design model proposed in the CityInduction project. This model includes three sub-models that support the formulation of design programs from contextual information, the exploration of designs solutions through a grammarbased generative approach, and the validation of designs against the program through the use of evaluation tools. To each of these sub-models corresponds a module in the envisioned platform and so, existing platforms are assessed in terms of their ability to support the implementation of each module. The current goal is a proof-of-concept implementation, but the final goal is the development of a complete platform for supporting urban design.
