summary	Aggregates are defined as large amounts of elements being in loose contact. In architecture they are mainly known as an additive in concrete construction. Relatively few examples use aggregates in their unbound form as an architectural material system in their own right. The investigation of potential architectural applications however is both a very relevant and unexplored branch of design research. Loose granular systems are inherently different from other architectural construction systems. One of the most decisive distinctions lies in the way information on those granular architectural systems is being generated, processed, and integrated into the design process. Several mathematical methods have been developed to numerically model granular behaviour. However, the need and also the potential of using so-called ,material’ computation is specifically relevant with aggregates, as much of their behaviour is still not being described in these mathematical models. This paper will present the current outcome of a doctorate research on aggregate architectures with a focus on information processing in machine and material computation. In the first part, it will introduce definitions of material and machine computation. In the second part, the way machine computation is employed in modelling granulates will be introduced. The third part will review material computation in granular systems. In the last part, a concrete example of an architectural aggregate model will be explained with regard to the given definition of material computation. Conclusively a comparative overview between material and machine computation in aggregate architectures will be given and further areas of development will be outlined.

title	Research on the Exploration of Sprayed Clay Material and Modeling System

summary	As a traditional building material, clay has been used by humans for a long time. From early civilisations, to the modern dependence on new technologies, the craft of clay making is commonly linked with the use of moulds, handmade creations, ceramic extruders, etc. (Schmandt and Besserat, 1977). Clay in the form of bricks is one of the oldest building materials known (Fernandes et al, 2010). This research expands the possibilities offered by standardised bricks by testing types of clay, forms, shapes, porosity, and structural methods. The traditional way of working with clay relies on human craftsmanship and is based on the use of semi-solid clay (Fernandes et al., 2010). However, there is little research on the use of clay slurry. With the rise of 3D printing systems in recent years, research and development has been emerging on using clay as a 3D printing filament (Gürsoy, 2018). Researchers have discovered that in order for 3D-printed clay slurry to solidify quickly to support the weight of the added layers during printing, curing agents such as lime, coal ash, cement, etc. have to be added to the clay slurry. After adding these substances, clay is difficult to be reused and can have a negative effect on the environment (Chen et al., 2021). In this study, a unique method for manufacturing clay elements of intricate geometries is proposed with the help of an internal skeleton that can be continuously reused. The study introduces the process of applying clay on a special structure through spraying and showcases how this method creates various opportunities for customisation of production.

title	Material Information: Integrating Material Characteristics and Behavior in Computational Design for Performative Wood Construction
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. 151-158

summary	Architecture as a material practice is still predominantly based on design approaches that are characterized by a hierarchical relationship that prioritizes the generation of geometric information for the description of architectural systems and elements over material specific information. Thus, in the early design stage, the material’s innate characteristics and inherent capacities remain largely unconsidered. This is particularly evident in the way wood constructions are designed today. In comparison to most construction materials that are industrially produced and thus relatively homogeneous and isotropic, wood is profoundly different in that it is a naturally grown biological tissue with a highly differentiated material makeup . This paper will present research investigating how the transition from currently predominant modes of representational Computer Aided Design to algorithmic Computational Design allows for a significant change in employing wood’s complex anisotropic behaviour, resulting from its differentiated anatomical structure. In computational design, the relation between procedural formation, driving information, and ensuing form, enables the systematic integration of material information. This materially informed computational design processes will be explained through two research projects and the resultant prototype structures. The first project shows how an information feedback between material properties, system behaviour, the generative computational process, and robotic manufacturing allows for unfolding material-specific gestalt and tapping into the performative potential of wood. The second project focuses on embedding the unique material information and anatomical features of individual wooden elements in a continuous scanning, computational design and digital fabrication process, and thus introduces novel ways of integrating the biological variability and natural irregularities of wood in architectural design.

title	Supporting Collective Intelligence for Design in Virtual Worlds: A Case Study of the Lego Universe
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. 637-652.
summary	Virtual worlds are multi-faceted technologies. Facets of virtual worlds include graphical simulation tools, communication, design and modelling tools, artificial intelligence, network structure, persistent object-oriented infrastructure, economy, governance and user presence and interaction. Recent studies (Merrick et al., 2010) and applications (Rosenman et al., 2006; Maher et al., 2006) have shown that the combination of design, modelling and communication tools, and artificial intelligence in virtual worlds makes them suitable platforms for supporting collaborative design, including human-human collaboration and human-computer co-creativity. Virtual worlds are also coming to be recognised as a platform for collective intelligence (Levy, 1997), a form of group intelligence that emerges from collaboration and competition among large numbers of individuals. Because of the close relationship between design, communication and virtual world technologies, there appears a strong possibility of using virtual worlds to harness collective intelligence for supporting upcoming ‚Äúdesign challenges on a much larger scale as we become an increasingly global and technological society‚Äù (Maher et al, 2010), beyond the current support for small-scale collaborative design teams. Collaborative design is relatively well studied and is characterised by small-scale, carefully structured design teams, usually comprising design professionals with a good understanding of the design task at hand. All team members are generally motivated and have the skills required to structure the shared solution space and to complete the design task. In contrast, collective design (Maher et al, 2010) is characterised by a very large number of participants ranging from professional designers to design novices, who may need to be motivated to participate, whose contributions may not be directly utilised for design purposes, and who may need to learn some or all of the skills required to complete the task. Thus the facets of virtual worlds required to support collective design differ from those required to support collaborative design. Specifically, in addition to design, communication and artificial intelligence tools, various interpretive, mapping and educational tools together with appropriate motivational and reward systems may be required to inform, teach and motivate virtual world users to contribute and direct their inputs to desired design purposes. Many of these world facets are well understood by computer game developers, as level systems, quests or plot and achievement/reward systems. This suggests the possibility of drawing on or adapting computer gaming technologies as a basis for harnessing collective intelligence in design. Existing virtual worlds that permit open-ended design ‚Äì such as Second Life and There ‚Äì are not specifically game worlds as they do not have extensive level, quest and reward systems in the same way as game worlds like World of Warcraft or Ultima Online. As such, while Second Life and There demonstrate emergent design, they do not have the game-specific facets that focus users towards solving specific problems required for harnessing collective intelligence. However, a new massively multiplayer virtual world is soon to be released that combines open-ended design tools with levels, quests and achievement systems. This world is called Lego Universe (www.legouniverse.com). This paper presents technology spaces for the facets of virtual worlds that can contribute to the support of collective intelligence in design, including design and modelling tools, communication tools, artificial intelligence, level system, motivation, governance and other related facets. We discuss how these facets support the design, communication, motivational and educational requirements of collective intelligence applications. The paper concludes with a case study of Lego Universe, with reference to the technology spaces defined above. We evaluate the potential of this or similar tools to move design beyond the individual and small-scale design teams to harness large-scale collective intelligence. We also consider the types of design tasks that might best be addressed in this manner.

title	Energy Performance Modeling of an Office Building and Its Evaluation – Post-Occupancy Evaluation and Energy Efficiency of the Building
source	Open Systems: Proceedings of the 18th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2013) / Singapore 15-18 May 2013, pp. 209-218

summary	Energy performance modelling can provide insights into the efficiency and sustainability of commercial buildings, and also the achievement of certification standards such as USGBC LEED. However, the results from the modelling must be validated via a post-construction evaluation, which quantifies any discrepancies between the predicted energy usage and the actual energy consumed. In this study, an existing office building was examined to test how well the model predicts energy usage. The results from the model were compared with the actual usage of gas and electricity over two years (2010-2011). Our study showed a 123% higher gas usage,and a 36% lower electricity, compared with the simulation. This difference presents that occupant behaviour and building construction practices have significant impact on the energy usage of a building. For instance, the large discrepancy among gas usage is due to the office building’s thermal envelope, which identifies the spots at which heat leaks out of the building, thereby forcing the heating unit to work more. Additionally, the post occupancy evaluation study identified that indoor environmental conditions impact on energy consumption of the building.

title	Assessing the Use of Advanced Daylight Simulation Modelling Tools in Enhancing the Student Learning Experience
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 303-313
summary	In architecture schools, where the ‘studio culture’ lies at the heart of students’ learning, taught courses, particularly technology ones, are often seen as secondary or supplementary units. Successful delivery of such courses, where students can act effectively, be motivated and engaged, is a rather demanding task requiring careful planning and the use of various teaching styles. A recent challenge that faces architecture education today, and subsequently influences the way technology courses are being designed, is the growing trend in practice towards environmentally responsive design and the need for graduates with new skills in sustainable construction and urban ecology (HEFCE’s consultation document, 2005). This article presents the role of innovative simulation modelling tools in the enhancement of the student learning experience and professional development. Reference is made to a teaching practice that has recently been applied at Portsmouth School of Architecture in the United Kingdom and piloted at Deakin University in Australia. The work focuses on the structure and delivery of one of the two main technology units in the second year architecture programme that underwent two main phases of revision during the academic years 2009/10 and 2010/11. The article examines the inclusion of advanced daylight simulation modelling tools in the unit programme, and measures the effectiveness of enhancing its delivery as a key component of the curriculum on the student learning experience. A main objective of the work was to explain whether or not the introduction of a simulation modelling component, and the later improvement of its integration with the course programme and assessment, has contributed to a better learning experience and level of engagement. Student feedback and the grade distribution pattern over the last three academic years were collected and analyzed. The analysis of student feedback on the revised modelling component showed a positive influence on the learning experience and level of satisfaction and engagement. An improvement in student performance was also recorded over the last two academic years and following the implementation of new assessment design.

title	Automated 3D Reconstruction of Interiors from Point Clouds
source	International Journal of Architectural Computing vol. 8 - no. 1, 55-73
summary	We present a new technique for the fully automated 3D modelling of indoor environments from a point cloud. The point cloud is acquired with several scans and is afterwards processed in order to segment planar structures, which have a noticeable architectural meaning (floor, ceiling and walls) in the interior. The basic approach to data segmentation is plane sweeping based on a hypothesis-and-test strategy. From the segmentation results, the ground plan is created through cell decomposition by trimming the two-dimensional ground space using half-space primitives. An extension in height of the ground contours makes the generation of the 3D model possible. The so-reconstructed indoor model is saved in CAD format for analysis and further applications or, simply, as a record of the interior geometry.

title	Urban micro-informatics: a test case for high-resolution urban modelling through aggregating public information sources
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 327-336
doi	https://doi.org/10.52842/conf.caadria.2010.327
summary	Our contention is that the city is a rich collection of urban micro-ecologies in continuous formation that include information types outside the traditional boundaries of urban design, city planning, and architecture and their native data fields. This paper discusses working with non-standard urban data types of a highly granular nature, and the analytical possibilities and technical issues associated with their aggregation, through a post professional masters level research studio project run in 2008. Opportunities for novel urban analysis arising from this process are discussed in the context of typical urban planning and analysis systems and locative media practices. This research bought to light specific technical and conceptual issues arising from the combination of processes including sources of data, data collection methods, data formatting, aggregating and visualisation. The range and nature of publicly available information and its value in an urban analysis context is also explored, linking collective information sites such as Pachube, to local environmental analysis and sensor webs. These are discussed in this paper, toward determining the possibilities for novel understandings of the city from a user centric, real-time urban perspective.

summary	Currently BIM is at the forefront of the building industry. While useful for various building types the definitive nature of healthcare design benefits from the BIM process largely in comparison to other building types. In this paper BIM is employed for phasing the design process of the healthcare project, creating modelling prototypes and making reference to a baseline model in order to increase the overall success of the healthcare design project.

title	'GHShot': a collaborative and distributed visual version control for Grasshopper parametric programming
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 3, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 35-44
doi	https://doi.org/10.52842/conf.ecaade.2019.3.035
summary	When working with parametric models, architects typically focus on using rather structuring them (Woodbury, 2010). As a result, increasing design complexity typically means a convoluted parametric model, amplifying known problems: 'hard to understand, modify, share and reuse' (Smith 2007; Davis 2011). This practice is in contrast with conventional software-programming where programmers are known to meticulously document and structure their code with versioning tool. In this paper, we argue that versioning tools could help to manage parametric modelling complexity, as it has been showing with software counterparts. Four key features of version control: committing, differentiating, branching, and merging, and how they could be implemented in a parametric design practice are discussed. Initial user test sessions with 5 student designers using GHShot Grasshopper version control plugin (Cristie and Joyce 2018, 2017) revealed that the plugin is useful to record and overview design progression, share model, and provide a fallback mechanism.

title	Patterns, heuristics for architectural design support: making use of evolutionary modelling in design
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 283-292
doi	https://doi.org/10.52842/conf.caadria.2010.283
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.

title	Applying augmented reality for data interaction and collaboration in BIM
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 511-520
doi	https://doi.org/10.52842/conf.caadria.2010.511
summary	Building Information Modelling (BIM) is expected to enable efficient collaboration, improved data integrity, distributed and flexible data sharing, intelligent documentation, and high-quality outcome, through enhanced performance analysis, and expedited multi-disciplinary planning and coordination. Despite these apparent benefits, the collaboration across the architecture, engineering and construction (AEC) disciplines is largely based on the exchange of 2D drawings. This paper reports the findings from a research project that aims at developing measures to enhance BIM-based collaboration in the AEC industry. Based on focus group interviews with industry participants and case studies of BIM applications, visualisation was identified as an interactive platform across the design and non-design disciplines. It is argued that visualisation can enhance the motivation for BIM-based collaboration through integration of advanced visualisation techniques such as virtual reality (VR) and augmented reality (AR). An AR interface for a BIM server is also presented and discussed in the paper. AR can open up potential opportunities for exploring alternatives to data representation, organisation and interaction, supporting seamless collaboration in BIM.

doi	https://doi.org/10.52842/conf.ecaade.2017.2.347
summary	The Waiheke Gateway Pavilion, designed by Stevens Lawson Architects originally for the 2010 New Zealand Venice Biennale Pavilion, was brought to fruition for the 2017 Headland Sculpture on the Gulf Sculpture trail by students from Unitec Institute of Technology. The cross disciplinary team comprised of students from architecture and construction disciplines working in conjunction with a team of industry professionals including architects, engineers, construction managers, project managers, and lecturers to bring the designed structure, an irregular spiral shape, to completion. The structure is made up of 261 unique glulam beams, to be digitally cut using computer numerical control (CNC) process. However, due to a malfunction with the institutions in-house CNC machine, an alternative hand-cut workflow approach had to be pursued requiring integration of both digital and analogue construction methods. The digitally encoded data was extracted and transferred into shop drawings and assembly diagrams for the fabrication and construction stages of design. Accessibility to the original 3D modelling software was always needed during the construction stages to provide clarity to the copious amounts of information that was transferred into print paper form. Although this design to fabrication project was challenging, the outcome was received as a triumph amongst the architecture community.

summary	The miniature replicas of multi-billion dollar property development projects provide every year a spectacle of the vast imagination of architects and master developers at Cityscape Dubai exhibition. The technical aspect of the model-making industry component is a complex one in that it often engages the modelling of very subtle structures such as twisted towers. One illustration of these is the Infinity Tower in Dubai Marina (designed by SOM). To be completed in 2011, this 330-metre high-rise is composed of 80 floors and is intended to be the world’s tallest high-rise featuring a 90_ twist. Each floor rotates by 1.2 degrees to attain the full 90_ spiral, creating the shape of a helix. The paper discusses the physical modelling of this tower, with a description of both the digital and the constructive parts.

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	In intelligent epoch, automatic parameter design systems reduce the requirements of the skills needed to create objects. The creator only needs to select the most perceptual primitive form to automatically generate the data system that iterates to the most efficient solution. In this paper, a method of combining performance driven optimization with parametric design is proposed. The iterative evolution is under the control of performance loop and fabrication loop, which makes all the data provided by parametric design in a practical project available for exploring structural analysis and digital prefabrication. Related to the case of surface steel structure, parametric optimization is not limited to a set of shape types or design problems, it would be based on the generality and built-in characteristics of parametric modelling environment in the most convenient and flexible way. (Rolvink et al. 2010)And the given parameters would be fed back on geometric structure, performance indicators, and design variables, so that designers can easily and effectively coordinate and try different solutions. The system transforms the generated data into machine language so that the process including design, analysis, manufacturing, and construction can maintain the orthogonal persistence of the data.

summary	Reconstruction work on more than twenty synagogues in Vienna has been ongoing for more than a decade. The fact that these sacred buildings no longer exist is a pivotal aspect in this undertaking. Research revealed archived material, however, which served as reliable basis for the reconstruction work. The paper focuses on the possibilities and limits of this exploration and discusses the long-term options for handling 3D models and the dissemination of results to a large audience. The appropriate illustration of spatial contexts is another aspect that has been explored. The publication of results in the form of a city guide is in line with the objective of conveying the reconstruction results to a large audience.

summary	The aim of this collaborative 3D printing workshop is to define the production specifications, the teaching-learning pedagogical strategy aspects to help architecture students acquire: the basic competences of building representation, the pre and post processing of printing procedures (printing materials, paint, epoxy, accessories, etc...), defining the missing functions in BIM and Architectural Modelling software and determining the benefits of enhancing them for better 3D prototyping productivity. Two teams (A and B) adopted specific working scenarios based on real world printing jobs. Team A worked on an in-house scenario and Team B on an outsourcing scenario. Tasks successfully completed showed: the wide range of prototypes that could be produced in an architectural studio and the need for a collaborative network to organize the knowledge and good practices developed by research teams (professional or academic) involved in developing rapid prototyping for architecture. This knowledge network could be a discussion forum and a development partnership of 3D printing manufacturers and CAD/BIM software developers.

title	Education to practice to ecology: A review and preliminary evaluation of a new architectural design curriculum using computational design tools and bamboo in Haiti
source	SIGraDi 2020 [Proceedings of the 24th Conference of the Iberoamerican Society of Digital Graphics - ISSN: 2318-6968] Online Conference 18 - 20 November 2020, pp. 643-651
summary	There is an absence of lightweight, sustainable construction materials in contemporary Haitian construction, a fact highlighted in the disproportionate loss of life in the 2010 Port-au-Prince earthquake. Between 2014 and 2017 the authors delivered a series of architectural design workshops in Haiti to raise awareness and develop design skills for bamboo using computational design tools. This paper provides a review of these workshops and a preliminary evaluation from surveys conducted with the course participants. Results showed architectural education had changed perceptions of bamboo and showed potential positive ecological impact due to subsequent reforestation activities instigated by participants. Weaknesses were in the lack of subsequent use of parametric modelling software. Bamboo material knowledge and a new architectural design methodology have been most relevant to their professional or academic work.

summary	This research introduces the concepts of virtual heritage in the field of architecture. It then continues with the fundamentals of virtual heritage (VH) metadata structure adopted from the UNESCO guidelines. The key highlights to the content of e-Warisan SENIBINA will be demonstrated via techniques to reconstruct heritage buildings towards a collaborative architectural virtual heritage experience as closely to originally design features. The virtual reconstruction will be based on the techniques suggested by the research team tested earlier in a smaller scale of advanced lighting technique for virtual heritage representations. This research will suggest (1) content preparation for creating collaborative architectural heritage, (2) effective low-polygon modelling solutions that incorporate global illumination (GI) lighting for real-time simulation and (3) texturing techniques to accommodate reasonable detailing and give the essence of the VH.
