title	Comparing Design Productivity Between Physical and Virtual Reality Modeling: Protocol Analysis for the Early Design Stages
source	C+++: Computation, Culture, and Context – Proceedings of the 11th International Conference of the Arab Society for Computation in Architecture, Art and Design (ASCAAD), University of Petra, Amman, Jordan [Hybrid Conference] 7-9 November 2023, pp. 996-1013.
summary	Investigating productivity in the design process by comparing physical and virtual reality modeling constitutes the problem defined by the study, since both mediums grant the interaction between the body and design object. The study, it is aimed to decode the productivity of the early design stages. The study uses the Linkography method and protocol analysis with the think-aloud method for the quantitative measurement and analysis of productivity. In the protocol analysis, the participants, all of them architects, were expected to propose a solution for the architectural design problem, first with a physical model and then with a virtual reality environment, three days apart. The results of the study show that the productivity results in the physical model are higher than the results in the virtual reality modeling. The differences suggest that the medium used in the design processes has a direct impact on the design process and productivity.

summary	Reasoning is influenced by our perception of the environment. New aspects of our environment help to provoke new thoughts. Thus, changes of what is perceived can be assumed to stimulate the generation of new ideas, as well. In CAD, computerized three-dimensional models of physical entities are produced. Their representation on the monitor is determined by our viewing position and by the rendering method used. Especially the wire-frame representations of views lend themselves to a variety of readings, due to coincident and intersecting lines. Methods by which wire-frame views can be processed to extract the shapes that they contain have been investigated and developed. The extracted shapes can be used as a base for the generation of derived entities through various operations that are called Reinterpretation Operations. They have been implemented as a prototypical extension (named Reint-Ops) to an existing modeling shell. ReintOps is a highly interactive exploratory CAD tool, which allows the user to customize criteria and factors which are used in the reinterpretation process. This tool can be regarded as having a potential to support conceptual design investigations.

source	Proceedings of the 2021 DigitalFUTURES The 3rd International Conference on Computational Design and Robotic Fabrication (CDRF 2021)
summary	‘Bio Scaffolds’ explores a series of design tectonics that emerge from a co-creation between human, machine and natural intelligences. This research establishes an integral connection between form and materiality by enabling biological materials to become a co-creator within the design and fabrication process. In this research paper, we explore a hybrid between architectural aesthetics and biological agency by choreographing natural growth through form. ‘Bio Scaffolds’ explores a series of 3D printed biodegradable scaffolds that orchestrate both Mycelia growth and degradation through form. A robotic arm is introduced into the system that can respond to the organism’s natural behavior by injecting additional Mycelium culture into a series of sacrificial frameworks. Equipped with computer vision systems, feedback controls, scanning processes and a multi-functional endeffector, the machine tends to nature by reacting to its patterns of growth, moisture, and color variation. Using this cybernetic intelligence, developed between human, machine, and Mycelium, our intention is to generate unexpected structural and morphological forms that are represented via a series of 3D printed Mycelium enclosures. ‘Bio Scaffolds’ explores an interplay between biological and computational complexity through non anthropocentric micro habitats.

title	Envisioning the RESPONSIVE milieu: An investigation into aspects of ambient intelligence, human machine symbiosis and ubiquitous computing for developing a generic real-time interactive spatial prototype
doi	https://doi.org/10.52842/conf.caadria.2005.421
source	CAADRIA 2005 [Proceedings of the 10th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] New Delhi (India) 28-30 April 2005, vol. 1, pp. 421-432
summary	The research paper exemplifies upon a design-research experiment conducted by the Hyperbody research group (HRG), TU Delft, Faculty of Architecture under the supervision of the Author and Prof. Kas Oosterhuis (director HRG and ONL). The research work, specifically aimed at developing a real-time interactive spatial prototype, fostering multiple usability of space: ‘The Muscle Re-configured’. The ensuing Muscle Re-configured project is essentially an architectural design research undertaking maneuvering on the precincts of augmented and virtual reality, exemplifying a fusion between the material and the digital counterpart of the architectural domain. This fusion is attained through harnessing a synergistic merger between the fields of ambient intelligence, control systems, ubiquitous computing, architectural design, pneumatic systems and computation (real-time game design techniques). The prototype is visualized as a complex adaptive system, continually engaged in activities of data-exchange and optimal augmentation of its (system’s) components in accordance with contextual variations.

title	A Holistic Documentation and Analysis of Timber Roof Structures in Heritage Buildings Using Scan to HBIM Approaches
doi	https://doi.org/10.52842/conf.ecaade.2024.1.715
source	Kontovourkis, O, Phocas, MC and Wurzer, G (eds.), Data-Driven Intelligence - Proceedings of the 42nd Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2024), Nicosia, 11-13 September 2024, Volume 1, pp. 715–724
summary	There is a great need for holistic documentation and management of heritage buildings using Historic Building Information Modelling (HBIM) frameworks. Limitations can be found in current literature regarding the accuracy, the level-of-detail, and the required attributes of final HBIM models, especially in cases where digital information intents to be used for the documentation of heritage timber roof structures. Previous research works indicate that geometry is created by the extrusion of the cross sections of the beams, and the usage of existing 2D drawings leading to simplified geometries in HBIM. This results in an absence of critical information, for example the bending of the wood, and its pathology. In this study, a novel Scan-to-HBIM methodology is exemplified and applied in heritage timber roof structures, which includes the implementation of recent remote sensing technologies for capturing the as-built data, with high levels of accuracy both in geometry as well as in pathology. In terms of geometry, algorithmic processes are used, that integrate parametric and BIM environments for the automatic creation of timber roof frames from point cloud data, which are adjustable to the abnormalities found in heritage buildings. As regards to pathology, high-resolution textured mesh models are created from photogrammetric procedures, which indicate in detail any possible defects to the existing timber elements. Detailed geometry and pathology are further analyzed, and a BIM database is created for documenting the typology, materiality, and level of damage to timber components. The methodology is tested on a Franko-Byzantine Timber roof Church in Cyprus, which includes a complex timber structural system.

title	DESIGN INFORMATICS: (A case based investigation into parametric design, scripting and CNC based manufacturing techniques)
doi	https://doi.org/10.52842/conf.caadria.2006.x.q9e
source	CAADRIA 2006 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Research in Asia] Kumamoto (Japan) March 30th - April 2nd 2006, 237-244
summary	The research paper exemplifies a novel information integrated design technique developed at ONL (Oosterhuis and Lenard), Netherlands, specifically appropriated for envisaging complex geometric forms. The ‘informed design technique’, apart from being highly instrumental in conceptualizing and generating the geometric component constituting architectural form in a parametric manner, is also efficiently utilized for precise computer aided manufacturing and construction of the speculated form. Geometric complexities inherent in contemporary architectural constructs and the time spent in appropriation of such topologies, fueled the ‘informed design’ approach, which caters to issues of timely construction, precision oriented design and production (visual and material) and parametric modeling attuned to budgetary fluctuations. This design-research approach has been tested and deployed by ONL, for conceiving ‘the Acoustic Barrier’ project, Utrecht Leidsche Rijn in the Netherlands and is treated as a generic case for exemplifying the ‘informed design’ technique in this research paper. The design methodology encourages visualizing architectural substantiations from a systems perspective and envisages upon a rule based adaptive systems approach involving extrapolation of contextual dynamics/ground data in terms of logical ‘rules’. These rules/conditionalities form the basis for spawning parametric logistics to be mapped upon geometric counterparts exemplifying the conception. The simulated parametric relations bind dimensional aspects (length, width, height etc.) of the geometric construct in a relational manner, eventually culminating in a 3D spatial envelope. This evolved envelope is subsequently intersected with a ‘parametric spatio-constructive grid’, creating specific intersecting points between the two. The hence extorted ‘point cloud’ configuration serves as a generic information field concerning highly specific coordinates, parameters and values for each individual point/constructive node it embodies. The relations between these points are directly linked with precise displacements of structural profiles and related scaling factors of cladding materials. Parallel to this object oriented modeling approach, a detailed database (soft/information component) is also maintained to administer the relations between the obtained points. To be able to derive constructible structural and cladding components from the point cloud configuration customized Scripts (combination of Lisp and Max scripts) process the point cloud database. The programmed script-routines, iteratively run calculations to generate steel-wire frames, steel lattice-structure and cladding panels along with their dimensions and execution drawing data. Optimization-routines are also programmed to make rectifications and small adjustments in the calculated data. This precise information is further communicated with CNC milling machines to manifest complex sectional profiles formulating the construct hence enabling timely and effective construction of the conceptualized form.

title	A study of 2D- and 3D-oriented architectural drawing production methods
source	Automation in Construction 5 (4) (1996) pp. 273-283
summary	The purpose of this paper is to present drawing production methods based on the difference between 2D- and 3D-oriented approaches. This study emphasizes the comparison of the two approaches in data production, updating and analysis. Architectural CAD drawings are outputted from design information through a computational interface. A drawing production model (P) can be represented by a database (DB) and an interface (I). The input interface is the input or update method between users and application systems. The output interface is the method of presenting architecture drawings like plans, elevations, sections and details based on input data. Under the constraints of a predefined data structure, the computational interface determines the efficiency and characteristics of input and output data. Drawing production methods can be classified into three types: segregating drawing files, applying reference files and constructing a virtual building model. These types come with different interfaces: 2D drafting has the same input and output interface, whereas constructing a 3D model is achieved using a different interface. A digital building model is defined as the electronic information of a whole building which is assembled by components with attributes. 2D- and 3D-oriented drawing methods are compared, based on items such as the required preparation before drafting, consistency of plans, elevations and sections, ease of modification, drafting efficiency, number of persons involved, and analysis potential.

title	Chain mail structures in architecture: a systematic, multi-scalar design exploration
doi	https://doi.org/https://doi.org/10.1007/s44223-024-00062-3
source	Architectural Intelligence Journal
summary	Chain mail structures, known for flexibility and adaptability, hold increasing promise for architectural applications, including transportable and reconfigurable systems. However, there is a dearth of knowledge on both systematic methods to design them, and complex behaviours of interlocking modules that comprise the structure. Preliminary studies, in response to this research gap, demonstrate the chain mail’s structural potential as programmable architecture. Nevertheless, to validate our models, we must move from the small scale to recognisably viable structures at an architectural scale. Acknowledging the multiscale prototype’s significance for developing new architectural systems, this study scales up chain mail structures from a small 1:10 scale to larger 1:2 and 1:1 scales. Employing a Research-Through-Design approach, we systematically addressed the challenges, focusing on module fabrication and prototype construction through analogue computation. Fabrication adjustments involve changing materials and modifying designs to suit manufacturing techniques. Additional design elements and process steps are needed to facilitate programming the larger scale structures due to the increased weight during construction. The research culminated in a full-scale saddle-like structure, illustrating the feasibility of direct scaling from smaller to larger scales and the expansive architectural potential of chain mail structures. In conclusion, the study successfully identified and responded to specific challenges related to the fabrication and construction of upscaled chain mail prototypes, aligning solutions with practical contexts. In doing so, this research contributes a set of considerations to enable more systematic design approaches for chain mail structural systems in architecture. At the same time, scaling up uncovers the inherent intelligence of these structures, providing a foundation for both empirical testing through analogue experimentation, and developing a predictive framework for their development and application in the field.

summary	Wood as a construction material gained interest in the last decade because of its low carbon footprint and the continuous research of new design possibilities opened using computational and robotic means. The shaping of timber into non-standard shapes is challenging and industrially demanding. This paper showcases a method to computationally control the formation of curved wood elements suitable for construction purposes. The aim is to achieve wood bending and twisting through a technique that combines advanced kerfing with a controlled insertion of wedges. The research has been conducted through material testing, computational developments, and robotic prototyping to evaluate design control, fabrication accuracy, and structural potential for architectural applications.

summary	One of the major downsides of concrete construction is the difficulty to be adapted, modified and deconstructed. In this work, we look at the potential enabled by the use of Additive Formwork based on Fused Deposition Modelling, in order to design and manufacture structural elements which can be assembled and disassembled easily. We call this new typology of structures Circular Concrete Construction. The paper illustrates an integrated computational workflow, which encompasses design and fabrication. Technological aspects of the 3D printed formwork and its application in reversible node and strut connections are described, with reference to the material and structural aspects, as well as prototyping experiments. The work is a proof of concept that opens perspectives for a new type of reversible concrete construction.

summary	In the 2020s, large scale 3D concrete printing (3DCP) is one of the most important areas of development for research and industry in construction automation. However, the available technology fails to adapt to the complexity of a real construction site and building process, oversimplifying design, production, and products to fit the current state of technology. We hypothesise that by equipping printing machinery with sensing devices and adaptive design algorithms we can radically expand the range of applications and effectiveness of 3DCP. In this paper we prove this concept through a full-scale design-to- fabrication experiment, SENS-ENV, consisting of three main phases: (i) we equip and calibrate an existing robotic setup for 3DCP with a camera which collects geometric data; (ii) building upon the collected information, we use environment-aware generative design algorithms to conceive a toolpath design tailored for the specific environment with a quasi-real-time workflow; (iii) we successfully prove this approach with a number of fabrication test-elements printed on unknown environment configurations and by monitoring the fabrication process to apply printing corrections. The paper describes the implementation and the successful experiments in terms of technology setup, process development, and documenting the outcomes. SENS-ENV opens a new agenda for context-aware autonomous additive construction robots.

summary	Despite its potential to decarbonise the built environment, wood is often found on construction sites as a source of waste rather than building material. In Denmark, wood is mainly used for temporary structures envisioned for short life cycles and single use, after which it is destined for incineration, defining it as “sustainable energy”. This research proposes an innovative design-to-fabrication process for sourcing timber waste as a valuable matter for a novel typology of structural elements, thereby extending their lifecycle and carbon sequestration capabilities. The work employs a voxel-based approach to designing and optimising complex wood structures, utilising computational stress analysis to determine material layouts reflecting the reclaimed stock. The physical construction voxels, with specific material strength and fibre orientation, are laminated into a functionally graded composite structure, namely the Re-VoxLam Beam. This prototype is demonstrated as a proof-of-concept of the proposed approach for decarbonising construction and upcycling wood waste.

summary	The paper discusses the process of computational design, analysis and fabrication for a lightweight super-thin gridshell structure. Digital form-finding based on Particle Spring Systems is used to define a compression-based shape, which is discretized through a parametric process into box-shaped components with embedded assembly and structural logics. Strategies to maximize the behaviour of anisotropic construction boards, double curved forms and assembly precision are described. Results are thoroughly documented to highlight the potential of the approach to rapidly build temporary gridshell structures.

summary	The amounts of material that is being extracted, harvested and consumed in the last decades is increasing tremendously and bringing to the serious problem of resource scarcity. As a direct consequence to this claim, designers are challenged to rethink architecture and develop new ways of confronting with materials. A potential answer to this problem is the exploration of computational logics for architectural design and fabrication inspired by the observation of biological formations. This work explores how the biological model of bone microstructure can be applied to a larger scale architecture that is structurally responsive, by means of computational design and Additive Manufacturing.

summary	This paper presents a computationally based methodology arising from the application of weaving techniques for the design and construction of an experimental architectural system, Weaving Enclosure. The research explores the close correspondence between material properties and assembly systems found in the traditional craft of weaving, studied through analytical and laboratory tests, and then implemented through computational design and digital fabrication. The workflow for the generation of specific geometries related to the elastic nature of the material results in the design and fabrication of a self- standing interior partition with digitally conceived patterns, tuned parametrically to provide structural and screening performance.

summary	The paper investigates the potential of auxetics in architectural applications by means of computational design and additive manufacturing. This class of metamaterials expresses interesting behaviour related to the unusual characteristics of a negative Poisson’s ratio. Different patterns have been studied through a design workflow based on parametric software and the use of Particle Spring systems to support the form-finding process of bending-active auxetic structures. An advanced understanding of their bending capacity is explored with the use of variable infill patterns informed by structural analysis. Furthermore, principles for the design and fabrication of auxetic gridshells are discussed.

summary	Advancements in computational tools are offering designers the possibility to change their relationship with materials. The exploration of auxetic metamaterials, specifically engineered to obtain properties beyond those found in nature, is the promising field examined in this paper. The aim is to define tools and methods in order to design auxetics, and use them to create efficient active-bending structures. By programming their geometry through several parameters, it is possible to finely control curvature and structural resistance. The paper describes an original investigation into the process of programming such structures through the use of combined computational tools.

summary	Concrete is undoubtedly the most employed material in constructions. In principle it allows to build complex architecture, where form can be for the realization of complex shapes. However, the biggest limitation of its use is explained by the demanding process needed to create free-form casts, it often limits its potential to obvious geometries. With the aim of overcoming current limitations, this paper explores the use of additive manufacturing to create formworks for concrete elements. The case study of a complex column is here utilized in order to develop an approach for advanced molds, where pressure levels, fluid dynamics of concrete and disassembly are integrative part of the design process. In conclusion are presented recommendations for further development at larger scale.
