title	A Computer-based Approach for Teaching Daylighting at the Early Design Stage
doi	https://doi.org/10.52842/conf.ecaade.1996.181
source	Education for Practice [14th eCAADe Conference Proceedings / ISBN 0-9523687-2-2] Lund (Sweden) 12-14 September 1996, pp. 181-190
summary	This paper has reviewed the literature on the teaching of daylight systems design in architectural education, and found that traditionally such teaching has evolved around the prediction of the Daylight Factor (DF%), i.e. illuminance, via two methods one studio-based and another laboratory based. The former relies on graphical and/or mathematical techniques, e.g. the BRE Protractors, the BRE Tables, Waldram Diagrams, the Pepper-pot diagrams and the BRE formula. The latter tests scale models of buildings under artificial sky conditions (CIE sky). The paper lists the advantages and disadvantages of both methods in terms of compatibility with the design process, time required, accuracy, energy-consumption facts, and visual information. This paper outlines a proposal for an alternative method for teaching daylight and artificial lighting design for both architectural students and practitioners. It is based on photorealistic images as well as numbers, and employs the Lumen Micro 6.0 programme. This software package is a complete indoor lighting design and analysis programme which generates perspective renderings and animated walk-throughs of the space lighted naturally and artificially. The paper also presents the findings of an empirical case study to validate Lumen Micro 6.0 by comparing simulated output with field monitoring of horizontal and vertical illuminance and luminance inside the highly acclaimed GSA building in Glasgow. The monitoring station was masterminded by the author and uses the Megatron lighting sensors, Luscar dataloggers and the Easylog analysis software. In addition photographs of a selected design studio inside the GSA building were contrasted with computer generated perspective images of the same space.

summary	The integration of technology into design work has always been seen as one of the serious problems in design education. In architecture the weak integration between architectural science, a subject based on objective knowledge, and artistic design which is based on tacit knowledge and creativity is a problem that has been debated to great length, and an issue of great importance to both academics and professionals. This paper raises the question: can a proper use of IT, both as a design tool and/or as a performance analysis tool, foster better integration and strengthen design quality? This paper investigates the relationship between Science, Design and Computer Aided Design. It aims to both highlight the problems facing the integration between architectural science and design, and describe a framework within which they can be analysed. The paper critically examines the following: a) The perceived gulf between science and design b) The parallels between hypothesis in design and hypothesis in science c) The basis of architectural design: intuition or research? d) Architectural Science and Computer Aided Design (CAD) and the role they can play into bringing about a marriage between science and design.The paper concludes by developing a conceptual framework that can be used as a vehicle to build a CAD system for use during the design process.

title	Creativity of ‘Process’ and ‘Product’: The Impact of Tools?
doi	https://doi.org/10.52842/conf.ecaade.2015.1.169
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 1, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 169-178
summary	This paper examines the relationship between creativity domains and computing tools. It reports on the findings of a design computing experiment with 2 groups of subjects while they were engaged with a problem solving design task using two types of CAD tools, non-parametric and parametric-algorithmic. The paper aims to address two questions. Does a more creative process by implication 'correlate' with and yield a more creative product? And does the 'type' of CAD tool deployed by the user impact on the creativity of their product? The findings revealed that creativity of the process correlated significantly with each measure of 'product' creativity, namely: novelty, technical goodness and aesthetic appeal. Factor loading on components confirmed two constructs, one for product creativity and another for process. Additionally a difference in CAD tools produced no statistical 'variance' in creativity of 'product' or process. A regression equation to predict product ratings from creativity process ratings is also presented.

title	Tools as Design Instruments: Computers and Cognition?
source	Global Design and Local Materialization[Proceedings of the 15th International Conference on Computer Aided Architectural Design Futures / ISBN 978-3-642-38973-3] Shanghai, China, July 3-5, 2013, pp. 1-12.
summary	This inquiry researches the impact of digital tools on the design process and empirically tests the association between computer aided design tools and each of cognition and creativity in architectural practice. The paper analyses the ‘design-tool’ relationship and reviews research in the field of computers as an instrument for creativity, examines their deductions and conducts a case study. Statistical analysis of the case study suggests that three measures of creativity correlated significantly with the length of time a subject spends using the computer in design: rho=0.487, P<0.05 for elaboration of design ideas; rho=0.605, P<0.05, for volume of ideas; rho=0.687, P<0.05, for ideation variety. Also, the length of designer-computer interaction seems to scaffold various forms of design reasoning and help cognition: rho=0.591, P<0.05. The study found little evidence to support the notion that computers prevent other forms of knowing.

title	Digital Processes in Architectural Design:A Case Study of Computers and Creativity
source	International Journal of Architectural Computing vol. 4 - no. 2, 95-120
summary	This paper describes the results of a statistical-experimental investigation into the relationship between three variables: design cognition, the computer as a problem solving medium and 'creativity'. The hypothesis put forward suggests a directional link between the use of 'CAAD as a cognitive design medium' and 'levels' of creativity in the design process. The hypothesis was tested statistically using first year architecture students as research design subjects. In order to place the research within a context, develop a thesis and identify 'operational' measures for variables, a literature search with special emphasis on 'creativity' was conducted. The statistical findings did confirm that levels of architectural 'creativity' in the design process and in the final product were somehow affected by the use of CAAD. Ideation fluency and originality, as 'creativity' indicators, correlated positively with CAAD as a cognitive medium with coefficients 3 0.5. The statistics from subjects- group design- revealed that computers' power of visualisation, slicing and Boolean operations has helped spatial ability and could eventually help novice designers to venture and create complex objects more than they would normally do with conventional media.

title	Intersection of Parametric Surfaces by Means of Look-Up Tables
source	IEEE Computer Graphics and Applications. October, 1983. vol. 3: pp. 39-48 : ill. (some col.). includes bibliography
summary	The intersection curve between parametric surfaces is important in such computer-aided design and manufacturing functions as shape design, analysis of drawing, design of fillets, and computation of numerically controlled tooling paths. The algorithm presented here provides an adequately accurate mathematical representation of the intersection curve. It also provides a database to simplify such operations as hidden-surface removal, surface rendering, profile identification, and interference or clearance computations. Further the algorithm facilitates creating and changing a finite element mesh in the intersection region

title	Modularity and Flexibility at the Small Scale: Evolving Continuous Material Variation with Stereolithography
doi	https://doi.org/10.52842/conf.acadia.2004.076
source	Fabrication: Examining the Digital Practice of Architecture [Proceedings of the 23rd Annual Conference of the Association for Computer Aided Design in Architecture and the 2004 Conference of the AIA Technology in Architectural Practice Knowledge Community / ISBN 0-9696665-2-7] Cambridge (Ontario) 8-14 November, 2004, 76-87
summary	In this paper, we introduce a technique by which the internal material properties of an object can be optimised at a microstructural level (5x10-5m) to counteract the forces that are applied to it. These can then be fabricated using the rapid prototyping method of stereolithography. The proposed technique is analogous to principles of mass customization and takes advantage of a flexible module to create complex structures in a manner that is computationally efficient and effective. The process is two-staged, in which a genetic algorithm evolves the topology of the microstructure and a second algorithm incorporating Finite Element Analysis then optimises the geometry. The examples shown are designed specifically for the fabrication technique, but the method and general principles are applicable to structural problems at any scale.

title	Automated Representation of Style by Feature Space Archetypes: Distinguishing Spatial Styles from Generative Rules
source	International Journal of Architectural Computing vol. 5 - no. 1, pp. 2-23
summary	Style is a broad term that could potentially refer to any features of a work, as well as a fluid concept that is subject to change and disagreement, yet approaches to representing it too often seek either a pre-defined set of generative rules or list of measurable features. Instead, a general and flexible method of retrospectively and automatically representing style is proposed based on the idea of an archetype, to which real designs can be compared, and tested with examples of architectural plans. Unlike a fixed, symbolic representation, both the measurements of features that define a style and the selection of those features themselves can be performed by the machine, making it able to generalise a definition automatically from a set of examples. This process is implemented in analysis, and coupled with a generative algorithm to produce plans in a learned style.

source	International Journal of Architectural Computing vol. 3 - no. 1, 107-126
summary	This paper presents an experimental approach that examines the response of non-architects to three virtual representations of architecture within a non-immersive Virtual Reality (VR) environment. It investigates the use of current digital technologies in their ability to facilitate early design stage sketch representation and explores the communication of early stage digital design proposals in order to determine the effect of representation type upon perception.

title	Digital Fabrication for Retroreflective Ceiling Treatment - Reducing Speech Distraction in an Open Work Environment
doi	https://doi.org/10.52842/conf.caadria.2018.1.317
source	T. Fukuda, W. Huang, P. Janssen, K. Crolla, S. Alhadidi (eds.), Learning, Adapting and Prototyping - Proceedings of the 23rd CAADRIA Conference - Volume 1, Tsinghua University, Beijing, China, 17-19 May 2018, pp. 317-325
summary	This paper presents a case study for the production of retroreflective ceiling treatment in an open work environment. In this setting with multiple talkers, speech distraction can be a significant cause of dissatisfaction and loss of productivity. Ceiling treatment in open plan work environments can provide an important way of ameliorating distraction from unattended speech, and rather than absorbing the sound at the ceiling, this paper examines the possibility of reflecting sound back to the source. Computational design and digital fabrication are integrated in this research for a site-specific deployment of the ceiling treatment and physical testing of prototypes in an acoustics laboratory. The contemporary possibilities that open up with new technologies to understand and resurrect faceted geometries and potentially vary historical precedents via new manufacturing techniques are demonstrated in these novel acoustic reflective ceilings that reflect sound back to their original source.

title	Acoustic Simulation and Conditioning in Vaulted Structures - Faceted Stereotomic Strategies for Multi-listener Spaces

summary	This paper examines faceted tessellations in an acoustic vault ceiling typology for the enhancement of human speech comfort in multi-listener environments. Geometric modelling explores simulated results for various tessellation arrangements within the overall segmentation of a global ceiling geometry. Where pattern-based design for acoustic surfaces often overlooks the optimisation of vault typologies, the tests demonstrated in this research seek a trade-off between acoustic properties and faceted detailing. This involves the performance-based design of micro joint topologies and ruled-surface geometries, and a macro-analysis of the vaulted surface for acoustic studies embedded into this workflow, using Pachyderm software.

title	A Human-Centred Framework for Sonic Mapping: Developing Representation Methods to Analyze Sonic Environments
source	Abdelmohsen, S, El-Khouly, T, Mallasi, Z and Bennadji, A (eds.), Architecture in the Age of Disruptive Technologies: Transformations and Challenges [9th ASCAAD Conference Proceedings ISBN 978-1-907349-20-1] Cairo (Egypt) [Virtual Conference] 2-4 March 2021, pp. 592-601
summary	This paper contributes to a new way of bringing the human physically into the in-situ environment and utilizing mapping methods of the actual sonic experience, which current acoustic studies and other environmental studies are lacking in their reliance on graphical representations. An entire era has been dominated by a visual communication of the sonic environment, yet sonic studies are not primarily dependant on visual experience. The paper reviews the possibilities of current methods of representation of the sonic experience. Representation, being crucial in the layperson’s perceptive awareness of key features of the environment can benefit from increased levels of listening methods. This includes mapping the qualities of information that reveal the environment.

summary	Simultaneous interdisciplinary architectural design from the very start of a project faces challenges in properly sharing information across disciplines. This research developed a method and related digital tool to improve collaborative design and aimed at making selected information to be shared faster and more transparently. The method consists of developing alternative parametric solutions for different parts of the design in such a way that crucial parameters form a link between these parts. The digital tool has been developed for Grasshopper and permits synchronic (real-time over the Internet) and a-synchronic sharing of these parameters. The design alternatives are evaluated with specific criteria, pros and cons in an Internet Forum and discussed via a video-conferencing tool. Decisions are then taken in a collaborative manner through voting. The paper describes the method based on a case study.

summary	New lighting technologies may fulfill a need for holistic design methods by offering opportunities for both architects and engineers to apply methods and knowledge from media technology that combine daylight and interactive light, in order to complement and deepen an understanding of context. The framework combines daylight and interactive light and includes human needs analysis, spatial understanding, qualitative analysis, qualitative tests and visual assessments. A transdisciplinary model termed the "Architectural Experiment" is applied in a specific case by combining serial, parallel and iterative processes which include contextual analysis, architectural design, simulation, C++ programming, implementation of the dynamic smart-film diffuser, programming of voltage ranges on Arduino boards, rapid prototype construction and lighting technology.

summary	This paper discusses Augmented Reality (AR) as means to interact with information regarding infrastructure projects before, under and after construction. For that purpose, two different prototypes were developed using Apples ARKit and Unity's game design platform and tested on two use cases. However, the main focus of this paper is interacting with infrastructure information through AR rather than researching core AR technology. We learned that using AR under the constructing phase with subsurface utilities is still facing several difficulties. Especially when it comes to accessing and interacting with information in a changing construction environment. These difficulties will be discussed and also the challenges regarding information flow between civil engineering and AR software.

title	Relation-Based Groupware For Heterogeneous Design Teams
doi	https://doi.org/10.52842/conf.ecaade.2001.086
source	Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 86-91
summary	This paper describes a work about coordination of concurrent engineering in the building construction and design. More particularly it describes the coordination of project teams which are heterogeneous and short-lived. The French context of the building trade is at present characterized by an increase of the quality requirements and by a reduction of the conception and realization delays. This induces the building sector to look for new modes of cooperation as they already exist in industry and services. With a few exceptions, the concurrent engineering tools taken from these sectors are not used in building projects. We make the assumption that the lack of use of these tools is due to the non-fitting of the common existing tools to the specificities of our sector. The solution we propose give a relational vision of the cooperation and the interactions existing during the processes of conception-construction in architectural works. Our first interest point concerns the representation of the actors, the documents and the assignments as a relational network and not as a hierarchical tree, mostly used in the groupware tools. In a second point, we use this relational network to produce a graphic and dynamic representation of the projects. The goal of this method is to reinforce the co-operation and the group awareness by supplying to the actors a good vision of the project evolution in order to increase the conception quality.

doi	https://doi.org/10.52842/conf.ecaade.2002.238

summary	The architectural conception is a particular cooperation situation. One characteristic of this cooperation is a “mutual prescription” between actors through a specific relational organization. Then each actor keeps up specific relations with others people (designers, project managers,…) but also with documents and activities. The representation of such network, which characterizes each project, is the one of the objectives of the “Relational model”. The existing groupware tools can not be directly used in the framework of the architectural conception. They require a high level of definition of procedures and exchanges, which is incompatible with the flexibility of current practices. The second objective of this model is to give to each actor an adapted vision of the project evolution. This representation has to be adapted to the role and the participation of the actor at each moment of the project life cycle. We propose in this article an open hyperdocument structure based on a relational model of cooperation. Some experimental views and navigations are exposed and commented. The integration of this new dimension allows to propose to the user an adapted vision of the project by taking into account the role he plays inside the project.

summary	This paper explores the use of subdivision algorithms for the production of three-dimensional ornament. In a first step, this paper presents modifications to the Catmull Clark and Doo Sabin processes’ weighting schemes. In a second step, it proposes how these modified processes can be applied specifically to the generation of ornament. It presents methods for specifying weights using parameters both intrinsic and extrinsic to the mesh. Strategies for working with both very uniform and more differentiated input meshes are considered.

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. 821-829
summary	We introduce a formal grammar as a computational approach to the generation of design. While existing shape-grammars transform primitive shapes as lines or rectangles, the presented production system specifically addresses polyhedral objects described by three-dimensional meshes composed of vertices, edges and faces. The parameters of the transformation rules are sensitive to topological and topographical properties of the selected input mesh. We demonstrate that this approach allows the creation of new ornamental structures and can lead to a new language of architectural forms.
