title	A Computer Aided Design Model for Climate Responsive Dwelling Roof
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. 315-332.
summary	Computer-Aided Design models have generated new possibilities in the sustainable design of buildings. Computer models assisting different aspects of architectural design have been developed and used for several decades. A review of contributions of computing to architectural design is given by Gero. Most of the conventional simulation computer programs do not actively support design development and optimization, specially at the formative design stages. It is well established that most decisions that affect comfort and building energy use occur during the formative design stages of the project. Furthermore, the efforts required to implement those decisions at the beginning of the design process are small compared to the effort that would be necessary later on in the design process. Therefore, if sustainable design issues are going to receive an appropriate level of consideration at the beginning of the design process, they must be presented in a way which is useful to the architect and fits with other things the architect is considering at that time. Design is seen as a problem-solving process of searching through a space of design solutions. The process of finding a solution to a design problem involves, identifying one or more objectives, making design decisions based on the objectives, predicting and evaluating the performance to find the acceptable decisions. Each of these activities can be performed inside or outside the formal model. In designing a roof, an architect or building designer has to make many decisions on the materials. The arrangement of these materials determines the aesthetic appearance of the roof and the house. Other considerations that affect the choice of roofing materials are thermal performance, rain, fire protection, cost, availability and maintenance. Recyclability of materials, hazardous materials, life-cycle expectancy, solutions, and design options as they relate to the environment also need to be considered. Consequently, the design of roof has become quite a complex and multifaceted problem. The principal need is for a direct design aid which can generate feasible solutions and tradeoff performance in conflicting requirements and prescribe the optimum solution. This paper presents a conceptual Computer Aided Design model for dwelling roof. It is based on generation and optimization paradigms of Computer Aided Design; which is diametrically opposite to conventional simulation. The design of roof (design goal) can be defined in terms of design objective as "control radiant and conduction heat." This objective must be satisfied to achieve the design goal. The performance variables, such as roof ceiling surface temperature or new thermal performance index (TPI*) must acquire values within certain ranges which will satisfy the objective. Given the required inputs, this computer model automatically generates prescriptive quantitative information to design roof to achieve optimum thermal comfort in warm humid tropics. The model first generates feasible solutions based on the decision rules; next it evaluates the thermal performance of the roof taking into account design variables related to the building‚Äôs roof and finally it applies numerical optimization techniques to automatically determine the optimum design variables, which achieve the best thermal performance. The rational and methodology used to develop the proposed model is outlined and the implementation of model is described with examples for climatic and technological contexts of India and Australia.

title	Interior Climate Optimization by Volumetric Adjustment
doi	https://doi.org/10.52842/conf.acadia.2011.x.j1c
source	Parametricism (SPC) ACADIA Regional 2011 Conference Proceedings
summary	This research focuses primarily on the functionality of software, specifically Rhinoceros (McNeel & Assoc.) and a few associated PlugIns (Grasshopper, Rhino Assembly), to create and control a model of a building to study the environmental effects of modulation of space. Has technology been completely utilized in addressing comfort maintenance within a dwelling space? For example, animals have a similarities based upon their surface to volume relationship, yet they are able to adjust the ratios based on a reaction to their environmental circumstances. For example, when cold, they are able to “fluff” their fur in order to minimize their surface area in comparison to an increasing “interior” volume. Historically, abilities to influence temperature change within a space have been relegated to passive air exchange systems and more recently completely active air exchange means of control. Technological advances have raised significant questions towards methods and means for this control. Through use of 3D models and simulations, the topic of climate maintenance in spatial conditions was addressed using environmental controls. Thus modulation of the interior climate as well as the space could simultaneously occur to create a radically different space of habitation. The preparation and writing of this abstract addressed various areas of the SPC requirements, which become apparent during the digestion of the paper.

title	Designing elastic transformable structures: Towards soft responsive architecture
doi	https://doi.org/10.52842/conf.caadria.2011.143
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 143-152
summary	This paper discusses the issues of designing and building environment involving spatial conditions that can be physically reconfigured to meet changing needs. To achieve this architectural vision, most current research focuses on the kinetic, mechanical systems and physical control mechanisms for actuation and structural transformation. Instead of the ‘hard’ mechanical joints and components, there is an unexplored ‘soft’ approach using lightweight elastic composite materials for designing responsive architectural skins and structures. This paper investigates the new possibilities for the manipulation of various architectural enclosures using ‘soft’ and elastic transformable structures, in response to environmental, communication and adapting to various contexts. This approach intends to minimise the mechanistic actuations and reduce weight for such operations. Therefore, this research introduces two modules (a tetrahedron and a cube) as responsive spatial models to test the potentials and limitations for the implementation of elastic materials with responsive capability towards reconfigurable architectural enclosure. Despite their individual differences, these experiments identify a trajectory for new possibilities for elastic architectural components that are more appropriate for ‘soft’ responsive architecture. We argue that this approach can provide an early hypothesis for design responsive architecture with a mix of passive and active design strategies.

title	Humanizing Parametricism
doi	https://doi.org/10.52842/conf.acadia.2011.x.d3g
source	Parametricism (SPC) ACADIA Regional 2011 Conference Proceedings
summary	As we increase the complexity and correlations of variables that are critical to the design of a project, we are becoming increasingly aware of the possibilities emerging from a computer integrated design process. There is such great opportunity to use these tools to manage and analyze multi variable design information, yet there is still much criticism of the design solutions created from computational design. These design solutions have been said to be “lacking any character, cultural influence, human engagement, or communication” and that “most of our contemporary architecture has forsaken this dimension of architectural discourse and it’s potential for exceptional spaces.” The current focus of computational investigation is primarily limited to building performance and optimization. Buildings that are designed from a purely optimizational construct without acknowledging the users desires and needs are falling short in creating “places”. Optimization can be the end result, but the constructs that are being optimized must be broadened to address all facets of a project. Computational design has emerged because it has the capacity to resolve multiple constraints and deal with extreme complexity of variables. By optimizing a more holistic set of constraints, computational architecture can truly provide comprehensive design solutions.

title	A study of variation of normal of polygons created by point cloud data for architectural renovation field
doi	https://doi.org/10.52842/conf.caadria.2011.321
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 321-330
summary	Acquiring current 3D space data of cities, buildings, and rooms rapidly and in detail has become indispensable. When the point cloud data of an object or space scanned by a 3D laser scanner is converted into polygons, it is an accumulation of small polygons. When object or space is a closed flat plane, it is necessary to merge small polygons to reduce the volume of data, and to convert them into one polygon. When an object or space is a closed flat plane, each normal vector of small polygons theoretically has the same angle. However, in practise, these angles are not the same. Therefore, the purpose of this study is to clarify the variation of the angle of a small polygon group that should become one polygon based on actual data. As a result of experimentation, no small polygons are converted by the point cloud data scanned with the 3D laser scanner even if the group of small polygons is a closed flat plane lying in the same plane. When the standard deviation of the extracted number of polygons is assumed to be less than 100, the variation of the angle of the normal vector is roughly 7 degrees.

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

title	Soft Responsive Kinetic System: An Elastic Transformable Architectural Skin for Climatic and Visual Control
doi	https://doi.org/10.52842/conf.acadia.2011.334
source	ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 334-341
summary	Most designers of dynamic building skins that reconfigure themselves in changing conditions have utilised mechanical systems. However, when designing for dynamic responsiveness, these systems often involve intricate and high-tech mechanistic joints, actuators and control. This research investigates the possibility of the ‘soft’ form-changing material systems to minimise the use of ‘hard’ mechanical components for kinetic responsive architectural skins. The research goal is to develop a prototype system that can be used to retrofit an existing building with an application of a ‘second skin’ that performs well in various climate conditions and is visually compelling. This approach is tested by the prototype, namely “Curtain”. It serves two fundamental purposes: Comfort and Cosmetic, to improve the existing interior and exterior spatial conditions. As an early proposition, the significance of this research offers a practical method for realising a ‘soft’ transformable architectural skin that synthesises passive cooling, manipulates sunlight and is set as an active shading device. Parametric design is used to explore and simulate these climatic and visual design constraints.

doi	https://doi.org/10.52842/conf.acadia.2011.x.q2q
source	Parametricism (SPC) ACADIA Regional 2011 Conference Proceedings
summary	To address the shortcomings of integrating building simulation in architectural design and to make it more appealing to students, a simple interface to Energyplus was created. This interface models a simple rectangular building that is passively heated by direct gain and cooled by ventilation. A simple photovoltaic interface has also been added to supply fan energy. This tool has an OpenGL modeler for visualization and uses Energyplus for calculations. The interface will run a full year simulation and graph the results. The results are reported in a yearly graph that shows the outdoor and indoor temperature. The indoor temperature range is based on adaptive comfort level. The interface was tested and used in an introductory design studio in order to comply with the 2010 imperative. The students simulated a simple box and changed the buildings parameters until the building fell within the adaptive comfort zone for most of the year. The climate simulated was Chicago, IL. Using these parameters the students then designed the building. The resulting designs show that even though the students were restricted in parameters, such as window percentage, they were still able to creatively design unique buildings that use zero to negative net energy for heating and cooling in a climate such as Chicago.

title	Preliminary Concept Design (PCD) Tools for Laboratory Buildings, Automated Design Optimization and Assessment Embedded in Building Information Modeling (BIM) Tools.
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 451-476.
summary	The design of laboratory buildings entails the implementation of a variety of design constraints such as building codes; design guidelines and technical requirements. The application of these requires from designers the derivation of data not explicitly available at early stages of design, at the same time there is no precise methodology to control the consistency, and accuracy of their application. Many of these constraints deal with providing secure environmental conditions for the activities inside laboratories and their repercussions both for the building occupants and population in general, these constraints mandate a strict control over the building‚Äôs Mechanical Equipment (MEP), in particular the Heating Ventilating and Air Conditioning (HVAC) system. Due to the importance of these laboratory designers are expected to assess their designs not only according spatial relationships, but also design variables such as HVAC efficiency, air pressure hierarchies, operational costs, and the possible implications of their design decisions in the biological safety of the facility. At this point in time, there are no practical methods for making these assessments, without having constant interaction with HVAC specialists. The assessment of laboratory design variables, particularly those technical in nature, such as dimensioning of ducts or energy consumption are usually performed at late stages of design. They are performed by domain experts using data manually extracted from design information, with the addition of domain specific knowledge, the evaluation is done mostly through manual calculations or building simulations. In traditional practices most expert evaluations are performed once the architectural design have been completed, the turn around of the evaluation might take hours or days depending on the methods used by the engineer, therefore reducing the possibility for design alternatives evaluation. The results of these evaluations will give clues about sizing of the HVAC equipment, and might generate the need for design reformulations, causing higher development costs and time delays. Several efforts in the development of computational tools for automated design evaluation such as wheel chair accessibility (Han, Law, Latombe, Kunz, 2002) security and circulation (Eastman, 2009), and construction codes (ww.Corenet.gov.sg) have demonstrated the capabilities of rule or parameter based building assessment; several computer applications capable of supporting HVAC engineers in system designing for late concept or design development exist, but little has been done to assess the capabilities of computer applications to support laboratory design during architectural Preliminary Concept Design(PCD) (Trcka, Hensen, 2010). Developments in CAD technologies such as Building Information Modeling (BIM) have opened doors to formal explorations in generative design using rule based or parametric modeling [7]. BIM represents buildings as a collection of objects with their own geometry, attributes, and relations. BIM also allows for the definition of objects parametrically including their relation to other model objects. BIM has enabled the development of automated rule based building evaluation (Eastman, 2009). Most of contemporary BIM applications contemplate in their default user interfaces access to design constraints and object attribute manipulations. Some even allow for the application of rules over these. Such capabilities make BIM viable platforms for automation of design data derivation and for the implementation of generative based design assessment. In this paper we analyze the possibilities provided by contemporary BIM for implementing generative based design assessment in laboratory buildings. In this schema, domain specific knowledge is embedded in to the BIM system as to make explicit design metrics that can help designers and engineers to assess the performance of design alternatives. The implementation of generative design assessments during PCD can help designers and engineers to identify design issues early in the process, reducing the number of revisions and reconfigurations in later stages of design. And generally improving design performance.

title	The Architecture of Flows: Integrated Infrastructures and the ‘Metasystem’ of Urban Metabolism
doi	https://doi.org/10.52842/conf.acadia.2011.040
source	ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 40-43
summary	The traditional approach to urban design studies has been based on what can be described as a generalised anatomical model, e.g., functional zoning coupled to metaphors such as green areas serving as the ‘lungs’ of cities. Despite the frequent use of biological metaphors, urban design has generally proceeded from an understanding of cities as static arrays of buildings and infrastructures that exist in, but are distinct from, stable environments. But this approach does not reflect the dynamic systems of cities throughout history, nor their close coupling to the dynamics of their local environment, climate and ecology, and now the global dynamics of culture and economy. The limitations of this approach, in which cities are treated as discrete artefacts, rather than nodes interconnected by multiple networks, are compounded by the legal and regulatory boundary of the city usually being defined as an older core, so that cities are regarded as something quite separate from their surrounding territory. All cities have administrative boundaries, but cities are very rarely either physically or energetically contained within those administrative boundaries. In the past, cities gathered most of the energy and materials they needed from their immediate local territory, and trade linked systems of cities across whole regions. The growth and vitality of many cities are no longer dependent on the spatial relationship with their immediate environs but on the regional and global flows of resources. The flow of materials, information and energy through cities comes from far outside their physical and regulatory (municipal) boundaries. Cities now extend their metabolic systems over very great distances, so that the extended territory of the urban metabolism of a city and its geographical ‘place’ are often completely decoupled.

title	Potentials for Multi-dimensional Tessellations in Architectural Applications
doi	https://doi.org/10.52842/conf.acadia.2011.308

summary	Computationally, there exist significant potentials to integrate periodic (repeating) and aperiodic (non-repeating) tessellations in architectural applications. While exploration of two-dimensional and three-dimensional tessellations appear in historically significant works, today, higher-dimensional tessellations are capable of being generated computationally which may be useful in various architectural applications. This paper, a collaboration between an architect and mathematician, explores these processes and potentials. Insights will be offered into this early stage exploration regarding the creation and use of higher-dimensional geometries for architectural applications—such as patterning, volumetric descriptions, and modular assemblages.

summary	Computer technologies are used frequently and effectively in film-making. It is almost inevitable to exclude computer aid in different phases of the process such as video editing, compositing and generation of visual effects. Therefore, techniques and software used in this field are improving every day. In this paper, potentials of a technique known in film making industry as matchmoving will be elaborated to be used in architectural design process. The types of software available for matchmoving purposes excel at generating 3D environment data from video shots, making them very useful tools for architects.

title	Designing responsive architecture: Mediating analogue and digital modelling in the studio
doi	https://doi.org/10.52842/conf.caadria.2011.155
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 155-164
summary	Prototyping digitally responsive architecture requires that architects know how to program and design electronics. Normally they don’t. The challenge for teachers is to teach these skills whilst maintaining a focus on the design potentials of responsive architecture. One method is to teach students to use Input-Output-Process (IPO) diagrams and parametric modelling as pathways into the logic of responsive architecture. The paper discusses the work of students taught this way during a semester long elective. Our analysis shows that IPO diagrams lead to reactive architecture, which matches the current technical limitations of responsive architecture. We argue that mediating analogue and digital models is an essential aspect to successful responsive architecture.

summary	Collaborative virtual environments clearly have potentials to enable innovative and effective education, involving debate, simulation, role play discussion and brain storming and project based group work etc. Integration of the collaborative virtual environments into the design curricula offers significant potentials for design schools. In this paper, based on our previous teaching in collaborative virtual environments, the student’s perceptions and evaluations of the courses, we discuss the pedagogy of design teaching in collaborative virtual environments, considering what skills the new generation of designers should have in terms of collaboration, communication and design.

summary	In this paper, we will explore the potentials of low-cost portable immersive environments that combine textile structures, gesture-based interfaces and multiple projections. Our aim is to develop affordable, easy to set up, portable and inviting immersive spaces that can serve as an interface between a web-based geographic virtual environment, experts and lay people. In this context, after the introduction, we will review a variety of methods, conceptual tools and materials related to textile tectonics and techniques which can be individually used or combined for the development and construction of portable immersive spaces. In the next section, we will discuss the opportunities and challenges of using a low-cost gesture-based interface (Kinect) to support “touchless” interactions. Consequently, we will present the design alternatives of low-cost portable immersive spaces that we have synthesized from our background studies. This will be followed by the observations and findings from our prototype development, implementation and preliminary testing processes. In conclusion, we will discuss our conclusions and recommendations regarding the future development of low-cost portable immersive spaces.

title	Formation Embedded Design: A methodology for the integration of fabrication constraints into architectural design
doi	https://doi.org/10.52842/conf.acadia.2011.122
source	ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 122-131
summary	This paper presents a methodology for the integration of fabrication constraints within the architectural design process through custom written algorithms for fabrication. The method enables the translation from three-dimensional geometry, or algorithmically produced data, into appropriately formatted machine codes for direct CNC fabrication within a single CAD modeling environment. This process is traditionally one-way with part files translated via dedicated machine programming software (CAM). By integrating the toolpath creation into the design package, with an open framework, the translation from part to machine code can be automated, parametrically driven by the generative algorithms or explicitly modeled by the user. This integrated approach opens the possibility for direct and instantaneous feedback between fabrication constraints and design intent. The potentials of the method are shown by discussing the computational workflow and process integration of a diverse set of fabrication techniques in conjunction with a KUKA 7-Axis Industrial Robot. Two-dimensional knife-cutting, large-scale additive fabrication (foam deposition), robot-mounted hot-wire cutting, and robot-assisted rod-bending are each briefly described. The productive value of this research is that it opens the possibility of a much stronger network of feedback relations between formational design processes and material and fabrication concerns.

summary	This paper is written for architectural researchers, practitioners and educators who explore the potentials of networked, location- aware, rich-media computing. Augmented and networked environments open new possibilities in urban and architectural design. At the same time, their adoption by the mainstream is underpinned – and constrained – by commercial motivations. To be able to counter the consumerist interpretation of inhabitable augmented environments, the field of architecture needs to foster a critical discussion of cyberspace. In turn, architectural education needs to provide students with the knowledge necessary to adopt cyberspace for creative purposes. The purpose of this paper is to invite further discussion and experimentation in this area.

summary	AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs. Building parameters are integrated in the report to provide insight on the variations among design alternatives.

title	Tree-Structure Canopy:A Case Study in Design and Fabrication of Complex Steel Structures using Digital Tools
source	International Journal of Architectural Computing vol. 11 - no. 1, 87-104
summary	This paper describes and reflects on the design and manufacturing process of the Tree-Structure canopy for the WestendGate Tower in Frankfurt upon Main, completed early 2011.The project investigated fabrication and assembly principles of complex steel structures as well as the integration of contemporary computational design, engineering, optimization and simulation techniques in a collaborative design approach. This paper focuses on the notion of modular standardization as opposed to non standard customized components. It also engages with issues relating to digital production tools and their impact on construction cost, material performance and tolerances. In addition it examines the reconfiguration of liability during a planning and construction process, an aspect which can be strongly determined by fabrication companies rather than the architect or designer.This paper is written as a reflection on the complete building process when contemporary digital tools are used from design through to fabrication. It studies both the generation of the steel structure as well the ETFE cushion skin. It reports on a collaborative project, where the main author was responsible for the canopies design, parameterization, digitalization and fabrication, as well as for the dissemination of the outcomes and findings during the design and realization process.As such it represents an example of research through design in a contemporary and evolving field.The canopy received a design award by the Hellenic Architecture Association.

title	InfoMatters, a multi-agent systems approach for generating performative architectural formations
source	International Journal of Architectural Computing vol. 9 - no. 3, 205-222
summary	The research paper exemplifies upon a computationally intensive inter-disciplinary research driven design investigation into spatializing the relationship between digital information and physical matter. Focusing on the development of architectural scale urban inserts, the design-research work operates on the intersection of information technology, environmental design, architecture, and computer aided manufacturing domains.The research framework revolves around developing a seamless integration of the aforementioned disciplines in order to establish iterative simulation driven methodologies for generating bottom-up sustainable architectural formations. This is achieved by establishing parametrically driven relational linkages between differential data sets (environmental, social, topological, material etc), which formulate the context (both global and local) within which the proposed project has to be designed. A selforganizing multi-agent system based simulation methodology for generating resultant spatial formations, in time, based on the impacts of the parametric relationships between the aforementioned data sets is eventually embarked upon. This implies, understanding the site as a dynamic information field within which interdependent ecology of agents (representing typology of people, program, structure, speed, desired social interaction etc) with multi-level relational affinities amongst each other as well as the dynamic urban information field. The resultant self-organized multi-agent formations are iteratively mined for identifying logical three-dimensional structural patterns or subjected to programmatic and environmental need driven additional layer of structural simulation with pre-embedded material restraints. An optimized system of multi-performative components that not only populates but also serves as an integrated structural + skin system of the results obtained from the agent based simulations (based upon the degree of inclusion/exclusion of parameters such as the amount of light, sound, wind etc) is subsequently generated. These experimental projects attained the status of self-evolving ecologies of multi-dimensional agents with embodied behavioural profiles, thus providing engaged, highly interdependent design by simulation outputs. The outputs showcase a dynamic system's driven approach towards sustainable design by stressing upon the idea of cohesively binding information and material systems from the very beginning of the design process. Such approaches help in reducing post-optimization of built form and consequently allow for rational understanding of performance criteria and its impact on formal articulations throughout the design process.
