summary	Following a previous study which investigated the verbal and visual elements of cyberspace, this study examines the relationship different academic training and the perceptions of the verbal and visual elements found in the previous study. The results of this study seems to indicate that the perception of the verbal elements is not relative to the subject’s academic training while the perception of the visual elements is.

title	The Re-creation of a Demolished House Based on Collective Memory
source	Immanuel Koh, Dagmar Reinhardt, Mohammed Makki, Mona Khakhar, Nic Bao (eds.), HUMAN-CENTRIC - Proceedings of the 28th CAADRIA Conference, Ahmedabad, 18-24 March 2023, pp. 363–372
doi	https://doi.org/10.52842/conf.caadria.2023.1.363
summary	This paper investigates how the collective memory of an architectural setting can be captured, re-created, and re-experienced. The method uses a workflow to create a Virtual Environment (VE) from diverse sources in an interpretational and iterative process. A case study was implemented to test this workflow, focusing on the re-creation of a now demolished family home based on information from multiple generations of a family. The workflow's main output is a VE in which the family members can re-experience the house and give continuous feedback. The essence of this workflow is the constant negotiation between remembered space in memory and its digital interpretation in the VE. The output was assessed and refined according to the users' feedback, which is used to loop back to specific stages in the workflow. This process revealed undisclosed histories and enhanced our understanding of this demolished site and its wider context. Moreover, the workflow provides a model for studying conceptually recreated spaces based on subjective sources and provides a user-centred experience in the VE.

doi	https://doi.org/10.52842/conf.caadria.1998.395
summary	This paper proposes a broader framework for understanding creativity by distinguishing different levels of creativity, namely personal and social/cultural creativity, and their interaction. Within this framework, the possible role that the computer can play could be further explored by analyzing the procedure of rule formation and the phenomena of seeing emergent subshapes.

title	A Connectionist Approach to Shape Recognition and Transformation
source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 19-36
summary	In human design processes, many drawings of shapes remain incomplete or are executed inaccurately. Cognitively, a designer is able to discern these anomalous shapes, whereas current CAAD systems fail to recognize them properly so that CAAD systems are unable to match left-hand-side conditions of shape rules. More unfortunately, as a result, current CAAD systems fail to retrieve right-hand-side actions. In this paper, multi-layered neural networks are constructed to solve the recognition and transformation of ill-processed shapes in the light of recent advances of connectionism in cognitive psychology and artificial intelligence.

summary	“Space” has long been an important concept in architecture;and architectural spaces and forms have been continuously evolved dueto the appearance of new concepts of space. Since the invention ofInternet, new spaces have been created through the computer. Tounderstand how human beings in the digital age experience these newvirtual spaces, and to discover the implications of the possible newconcepts of space into the physical architectural world, this paperdiscusses the nature of virtual spaces by examining the verbal and visualelements involved in the creation of a sense of virtual spaces. All theverbal and visual elements of virtual spaces discovered through ourexperiments and interviews are presented. It is found that the three coreelements of both verbally and visually constructed virtual spaces are:movements, interactions, and acoustic effects. In addition, a comparisonbetween verbally and visually constructed spaces, and between physicaland virtual spaces are explored. Finally, further studies related to therole of digital media in the construction of a sense of space aresuggested at the end of this paper.

title	Micro-scale weather data for energy performance assessment in Singapore
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 229-238

summary	Weather data plays an important role for energy perfor- mance assessment in the design of buildings and urban environments. Many researches have been carried out to generate and analyse vari- ous weather files for different simulation platforms. However, investi- gations have been lacking in the development of weather files that ac- count for urban heat island (UHI) problems. As a result of global warming and the complexity of the urban environment, the weather file for a modern city cannot be simply based on climate information from 20 years ago. The objective of this research is to demonstrate a method for creating different micro-scale typical meteorological year (TMY) weather files based on different urban texture values. This re- search includes three steps: 1) Recent years weather data is obtained. 2) Considering the UHI impact, a series of new TMY weather files are generated for different micro-scale areas in Singapore based on rele- vant urban texture variables. 3) A comparison of the results shows that there is a big difference between the new and the old TMY. The tem- perature of the new TMY is 1-2°C higher, while the solar radiation is lower than the original TMY data. Hence the new weather files will be more credible than the original TMY for energy performance simula- tion in the design process.

title	A Data-Driven Approach for Interpreting Human Preference in Urban Public Spaces: A Case Study in London
source	Immanuel Koh, Dagmar Reinhardt, Mohammed Makki, Mona Khakhar, Nic Bao (eds.), HUMAN-CENTRIC - Proceedings of the 28th CAADRIA Conference, Ahmedabad, 18-24 March 2023, pp. 625–634

summary	Sound, an often easily overlooked part of the urban composition, plays a crucial role in urban studies regarding how people perceive urban acoustic environments. Influenced by variable natural and artificial acoustic elements, the multi-level nature of urban soundscapes reflects multidimensional urban characteristics and thus demands thorough investigations. Unravelling the acoustic complexity and understanding its influence on public spaces' popularity will benefit the interpretation of urban soundscapes and help to build a more vibrant public life. In this paper, we utilize DepthMapX and QGIS to select specimen sites for further investigation. The behavioural analysis is performed through principle components analysis (PCA) and K-Means analysis based on data obtained within the city of London. This project seeks to develop digital strategies to investigate the relationship between urban public spaces and their soundscapes: to infer the correlation between people's emotions and the richness of urban environments. Through integrating machine-learning analytic approaches into visualizing how citizens perceive or experience the urban sound environment, our research aims to positively assist and inform urban practitioners in planning and designing more benign acoustic environments.

title	Discovering the design problem
source	Design Studies, Vol 15, No 2, 125-140
summary	The design disciplines of architecture, engineering, and computer science have provided three distinct models of the design process. We hypothesize that these models merely indicate three approaches to design, and that fragments of all three models will be found in any one discipline. To discuss this issue we present a discipline-independent cognitive framework which we then apply to a protocol analysis study of five engineering designers. Our results indicate that the designer's experience plays a key role in determining the design process.

summary	This study aims to develop the application and exploration of digital manufacturing technology in the design of textile composite materials in the digital fabrication. The inspiration for this study comes from the folds of mushrooms and resulting caps. In nature, many organisms grow flexible bodies as structural systems instead of relying on hard bones. This raises the question of whether soft textile materials can also have the potential to serve as structural support materials. Research is divided into three parts. The first part aims to understand the application of non-woven fabrics in the construction field, and examine the manufacturing and reprocessing methods of composite materials. The second part aims to establish the logic of form finding and shape optimization. The third part is the design and manufacturing stage. This research not only establishes a digital fabrication work-flow based on composite fabric materials but also develops a large-scale self-supporting structure as a verification of this process.

source	SIGraDi 2003 - [Proceedings of the 7th Iberoamerican Congress of Digital Graphics] Rosario Argentina 5-7 november 2003
summary	The foreshadowing and transfiguration of architectural space using digital technologies proposes a new order among the physical, symbolic and digital interrelations, where these entities coexist, not only as part of the process that orchestrates thought, but as important mechanisms within the creative process. So we accept that the potentiality of a computerized diagrammatic model expresses more that simply functional aspects, becoming the representation of thought, problems solving and communication, developing images that allow us to explore and to evaluate alternatives, bringing closer objects that we perceive by means of the senses, as well as those that we imagine or dream of.

summary	This paper presents the example of the reconversion of an important tram station from the origins of electricity in Portugal that was still in use until the late 1990’s but became redundant since then. Its significant urban presence and the importance of preserving the memory of the old trams that were still in use some years ago in Lisbon, led to an innovative solution, combining public value and heritage protection. In 2011, the Lisbon City Council agreed to give the building and its site for university use, namely to be transformed into a student’s facility, as a study, leisure, recreational and cultural space of the IST, open 24h a day. This new university building, located just one block away from the traditional IST compound, was called IST Learning Center and extended the notion of campus outside its walls and into the city’s urban fabric.

summary	The paper discusses the intersection of two main agendas for Chilean governments that are BIM (Building Information Modeling) and BEAM (Building Environmental Assessment Methods). It shows the state-of-the-art in both fields in Chile as well as in the world, it discusses some previous efforts of integration; it found some new opportunities for collaboration and finally proposes a new framework that brings together BIM and BEAM. The development of the method includes BIM Models, databases and spread sheets for building energy Certification, it finally provides a semi-automatic environment where architects model their design in BIM and this Information is used as an input to the certification process. Potentials and risk of this method are discussed.

summary	The work compiles several academic and Research initiatives, and aims to establish a right link between two agendas that governments, AEC industry and academia normally handle separated, this is BIM (Building Information Modeling) and Wood. By running several literature reviews, interviews and software tests, the state-of-the-art was reached in both fields; several cases linking BIM and wood are shown and discussed. It can be concluded that both fields have several commons processes and also that many cases have used just a few BIM tools, disregarding a big potential of these methodologies.

source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	Our current research is focused on the optimization and evaluation of the architectural building design (gestalt), related and in balance to the inner organization of a building, the floorplan layout. This paper is focused on the impact of Space Layout Planning supported by Information and Communication Technologies (ICT) applied to Architectural Design. We present an overview and wide description of the „architectural design“, the classical definition and methods; and its evolution in practice since the ICT tools impact of the last forty years. Definition such as space program, space relationships, space function are wide discussed to understand the phenomena of architectural layout design, the parameters, variables, constraints and goals of each design. Second we present the state of the art and the current techniques and approaches (optimization, generative systems, artificial intelligence, genetic algorithms, physically based modeling, etc), a classification structure is generated to visualize the areas of impact and use of each technique (different areas from architectural design). Finally we described a complete framework to research and develop our own methodologies based on a specific case of architectural design, the current CAD tools and the possible develop of new tools using the impact of BIM systems.

summary	The Research focuses on possible links between (Building Information Modeling), the Building Energy Performance Requirements and BPS software (Building Performance Simulation). It is expected to establish critical paths within the interoperability processes between BIM and BPS to support architects and energy consultants to choose the most appropriated workflow for the analyzed buildings to fulfill the performance requirements given by the Chilean laws. Several study cases in interoperability and the state-of-the-art are presented and discussed. Finally a novel map of relation between these three areas is presented.
