title	The Colors We Share
source	ACADIA 2023: Habits of the Anthropocene: Scarcity and Abundance in a Post-Material Economy [Volume 1: Projects Catalog of the 43rd Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 979-8-9860805-8-1]. Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 40-47.
summary	The Colors We Share is the winning proposal for a permanent public art installation that will be built in Los Angeles’s Little Tokyo (Figure 1). Selected through a rigorous open Request for Proposals (RFP) process organized by the city, the project honors the community’s rich and multivalent history and celebrates the voices of its next generation. In collaboration with the Little Tokyo Service Center (LTSC), the installation will feature a digital archive and will incorporate imagery gathered through social media to connect with other Nihonmachi (Japanese-descendant) communities across the globe in real time (Densho, n.d.). The vision for the project is two-fold: 1) to construct a vertical gateway that connects with the adjacent neighborhood, and 2) to create a dynamic display that allows community members to see themselves in the structure and connect with other Nihonmachi through locally, nationally, and internationally collected images and colors (Figure 2). In reference to the conference theme, this digital interface draws upon Dana Cuff and Jennifer Wolch’s Urban Humanities framework and creates a physical landmark that parses through an abundance of information to reveal the scarce voices and stories of a minority population (Cuff and Wolch 2016).

title	The language of design: Spatial cognition and spatial language in parametric design
source	International Journal of Architectural Computing vol. 14 - no. 3, 277-288
summary	This article develops a new research framework and method combining cognitive and linguistic approaches to investigate parametric design. At the core of this new approach is a dual-coding system for protocol analysis, which can formally capture both cognitive and linguistic characteristics of the design process. In this article, the method is applied to the analysis of the results of a design experimental undertaken by a set of Australian and Swedish architects working individually in a parametric environment. The results of the experiment demonstrate the effectiveness of the dual-coding system and, with the support of linkography, facilitate the in-depth exploration of design cognition and its relationship to spatial language. This method directly contributes to a new insight into the role of language in design.

title	Cultural Difference in Colour Usages for Building Exteriors Focusing on Theme Park Buildings
doi	https://doi.org/10.52842/conf.caadria.2016.621
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. 621-630
summary	The notion of globalisation has become widely spread in various fields, and accordingly, it is increasingly more important to take account of indigenous culture characteristics in each field. An as- pect of achieving globalisation, globalization with local consideration, is to consider the difference of colour usage between distinct cultures. This study suggests an approach to investigate the colour difference between eastern and western cultures with the case analysis of build- ing fac?ade colours in Disneyland Paris and Tokyo Disneyland. We an- alysed cultural colour usage characteristics and derived tendencies for both Paris and Tokyo Disneyland building fac?ade colours. To do this, we use image based k-means clustering algorithm and CIELAB colour space distances to explore colour characteristics. Our analysis indi- cates an overall colour usage tendency that Paris uses more green and bluish colours and Tokyo uses more red and yellowish colours for building fac?ades, based on CIELAB colour space values. The major motivation of this paper was to reflect the atmosphere and the mood of the space that can be easily felt but not readily expressible into a cultural colour palette. Eventually, by finding the characteristics of perceived colours, we hope to create a colour recommendation system for different cultures based on cultural clues.

title	Development of schematic estimation system through linking QTO with Cost DB
doi	https://doi.org/10.52842/conf.caadria.2016.507
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. 507-516
summary	Cost estimate in architectural projects is an important factor for decision-making and financing the project in both early design phase and detailed design phase. In Korea, estimate work based on 2D drawing has generated problems of difference form QTO according to worker’s mistake and know-how. In addition, 2D-based estimation are obtained uncertainty factors of estimation depending on lack of infor- mation due to becoming larger and more complex than any other pro- ject of the architectural project. In order to solve limitations, this study is to suggest an open BIM-based schematic estimation process and a prototype system within the building frame through linking QTO and cost information. This study consists of the following steps: 1) Ana- lysing Level of Detail (LoD) to apply to the process and system, 2) BIM modelling for open BIM-based QTO, 3) Verifying the quality of the BIM model, 4) Developing a schematic estimation prototype sys- tem. This study is expected to improve work efficiency as well as reli- ability of construction cost.

summary	With the work-in-progress research project ColorTracker we explore color as a formal design tool. This project-based paper describes a novel software application that processes color composition of a place and transcribes the data into three-dimensional geometries for architectural design. The research comprises two parallel trajectories: a theoretical survey and the software application design. The theoretical survey presents the historical background of color. The project-based research seeks to develop digital methods and techniques that analyze the color compositions of the environment. Subsequently the objective is a novel application software for smart mobile devices in order to demonstrate the potentials of examining the color composition and chromatic parameters of a given environment and how it can contribute to the design.

title	Investigating cultural uniqueness in theme parks through finding relationships between visual integration of visitor traffics and capacity of service facilities
source	International Journal of Architectural Computing vol. 14 - no. 3, 247-254
summary	The goal of the article is to find the relationships between theme park visitor traffics and service facility location along with their capacities. To do that, we analyzed four Disneylands situated in Paris, Tokyo, and the United States (Florida and California). By analyzing the visual integration of visitor traffics at each Disneyland and calculating the capacities of service facilities such as the attractions, shops, and restaurants, we ran through a linear and a geographically weighted regression analysis. Our results indicate that there is a unique relationship between the service facility placements and the amount of predicted traffic flows for each Disneyland.

title	The Expansion of Virtual Landscape in Digital Games: Classification of Virtual Landscapes Through Five principles
source	Gülen Çagdas, Mine Özkar, Leman F. Gül and Ethem Gürer (Eds.) Future Trajectories of Computation in Design [17th International Conference, CAAD Futures 2017, Proceedings / ISBN 978-975-561-482-3] Istanbul, Turkey, July 12-14, 2017, pp. 567-584.
summary	This research established classification system which contains five principles and variables to classify the types of the virtual landscape in digital games. The principles of the classification are Story, Space Shape, Space and Action Dimension, User Complexity and Interaction Level. With this classification system, our research group found the most representative types of virtual landscape in the digital game market through 1996 to 2016. Although mathematically there can be 288 types of virtual landscape, only 68 types have been used in the game market in recent twenty years. Among the 68 types, we defined 3 types of virtual landscape as the most representative types based on the growth curve and a number of cases. Those three representative types of virtual landscapes are Generating / Face / 3D-3D / Single / Partial, Providing / Chain / 3D-3D / Single / Partial and Providing / Linear / 2D-2D / Single / Partial. With the result, the researchers will be able to establish the virtual landscape design framework for the future research.

title	Developing a Workflow for Daylight Simulation
doi	https://doi.org/10.52842/conf.caadria.2016.363
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. 363-372
summary	Daylight simulations are occasionally used as active tools in regards to local governing regulations, which are necessary for providing documentation. Simulation tools have been avoided in the past due to their barriers. Daylight simulation tools are used within documentation design stages as ‘passive tools’, however they do not have a direct impact on the architecture design decisions, as passive tools are used by engineers usually to derive material and glass speci- fications. Recent developments within an online community have pro- vided designers with access to daylight simulation tools within a de- sign platform accessible data can be modified and represented with local governing codes to provide designers with relevant information. The paper aimed to develop an active daylight simulation tool within a design platform. Data is filtered with the Green Star benchmarks to export visual information as well as a voxel matrix instead of 2D lu- minance maps. This paper outlines a workflow of the simulation tool used to evaluate daylight performance of a selected building as a case study in real time. The paper also details potential problems and justi- fied suggestions derived from the analysis for the building to reach the requirements within the Green Star Multi Unit Residential.

title	An Intuitive Heritage Education System for Learning Architectural Structures and Styles - Focusing on the historical Korean architectures
doi	https://doi.org/10.52842/conf.ecaade.2016.2.529
source	Herneoja, Aulikki; Toni Österlund and Piia Markkanen (eds.), Complexity & Simplicity - Proceedings of the 34th eCAADe Conference - Volume 2, University of Oulu, Oulu, Finland, 22-26 August 2016, pp. 529-537
summary	Although national and international attention toward the cultural heritage is on a rise, there is a lack of public attention toward cultural heritage sites. One of the main problems is the lack of interaction and the visualization of cultural heritage on the sites. Especially Korean historical architectures are structurally complex and are not easily understood by common people. To improve the public awareness of architectural heritages, we propose a model-based diagnosis system to educate the visitors and tourists. The system is designed to guide the users to model an appropriate architecture in accordance with the era, location, and the usage. For the system, we built a robust set of cases based on the ontological structure we designed especially for architectural heritage education. It basically enables users to reconstruct buildings intuitively in six steps from bottom to top. A system evaluation was conducted on the affective, cognitive, operative aspect of the system at a heritage site. The results show well in terms of cognitive aspect but was evaluated poorly in terms of the operative aspect.

title	Architecture of Intermodal Complex
doi	https://doi.org/10.52842/conf.ecaade.2016.2.297
source	Herneoja, Aulikki; Toni Österlund and Piia Markkanen (eds.), Complexity & Simplicity - Proceedings of the 34th eCAADe Conference - Volume 2, University of Oulu, Oulu, Finland, 22-26 August 2016, pp. 297-303
summary	This paper focuses on the conception and design of architecture as the work of producing media about buildings and other environmental artifacts. I approach the questions regarding simplicity and complexity through "interdependence" and "intermodality." I believe the two concepts offer more precise frames of relations and contexts involving simplicity and complexity. I will first discuss the complexity as a condition of interdependences and how today's interdependences may provide a framework to understand complexity. I will then propose that intermodality adds to interdependence a notion that specifically pertains to today's media-driven culture and its complexity. I will next discuss how dependences and modalities are interconnected at various levels and eventually producing a new kind of semiosis that results from the disjunction between the medium and the content. I will in conclusion propose a new concept "apparatization" driven by interdependence and intermodality and how it changes shape and remain fluid, rather than scaling between simplicity and complexity, without a specific physical locus.

title	Investigating Audience Satisfaction Base on the Nonverbal Language Analysis of the Audience in Photos
source	Ji-Hyun Lee (Eds.) "Hello, Culture!" [18th International Conference, CAAD Futures 2019, Proceedings / ISBN 978-89-89453-05-5] Daejeon, Korea, pp. 317-330
summary	When we want to know satisfaction of audiences in a speech, the questionnaire survey is the most affordable method to collect quantitative data. However, the reliability and validity of the questionnaire is closely related to the design of the questions and the attitude of the respondents. Photos can capture nonverbal behaviors of the audience while listening to a speech. At that time, the audience did not hide their emotions. In this paper, we organize the photos of the three speeches hosted by the NCKU Art Center in 2016 as the data set. We found that the results of the behavioral analysis in photos are similar to the statistical results of the questionnaire. Finally, we made some suggestions for using the photos to analyze the nonverbal behavior of audiences and for establishing a database of nonverbal behaviors.

title	Finding relationships between movement and tree planting patterns in theme parks
doi	https://doi.org/10.52842/conf.caadria.2016.135
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. 135-144
summary	Tree planting in design practice is considered simply as void fillers or view blockers. However, for a sustainable design, creat- ing places using trees need to be reconsidered. Going beyond tradi- tional tree plantings in urban environments, an application of compu- tational methods in landscape architecture for the management of the complex system is needed. While computational methods have been extensively applied to buildings, less has been applied to trees. The goal of this paper is to investigate how the presence of trees affects human movement and find out if computational methods can be used for recommending tree planting patterns. We analysed the tree plant- ing patterns in renowned theme parks as an initial research categoriz- ing tree planting patterns, using an agent-based analysis for simula- tion, and comparing the results of the average agent counts in theme park plans without trees and those with trees. We noticed there was a clear distinction between tree planting pattern types and the change in agent counts supporting the qualitative theory in landscape architec- ture. The result of this research can guide theme park designers as well as urban park designers when deciding which tree planting pat- terns to implement for the purpose of controlling pedestrian move- ments.

title	Daylighting Based Parametric Design Exploration of 3D Facade Patterns
doi	https://doi.org/10.52842/conf.ecaade.2016.2.379
source	Herneoja, Aulikki; Toni Österlund and Piia Markkanen (eds.), Complexity & Simplicity - Proceedings of the 34th eCAADe Conference - Volume 2, University of Oulu, Oulu, Finland, 22-26 August 2016, pp. 379-388
summary	A building façade plays an important role of reducing artificial lighting by introducing natural light into the interior space. A majority of research and current technology heavily focuses on the optimization of window properties such as the size, location, and glazing with the consideration of external shading device as well as the building wall in order to obtain appropriate natural lit space. In the present work, we propose a 3-dimensional approach that can explore the trade-offs between two objectives, daylight performance and electricity generation, by means of paramedic modeling and multi-objective optimization algorithm. The case study was simulated under the environmental setting of the geographical location of Incheon, Korea without any urban context. Using the proposed methods, 50 pareto-front optimal solutions were derived and investigated based on the achieved daylighting and generated electricity.

title	Definition of a Domain-specific Language to Represent Korea Building Act Sentences as an Explicit Computable Form
doi	https://doi.org/10.52842/conf.caadria.2016.073
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. 73-82
summary	This paper aims to define the syntax of KBimCode Lan- guage as a domain-specific computer language to represent Korea Building Act sentences. KBimCode Language represents building permit requirements in Korea Building Act as explicit computable rules. KBimCode aims to accomplish the neutral and standardized way of rule-making in an easy-to-use syntax. This paper introduces the approach of language design and definition. The main concerns handled in the paper are: 1) features of building permit-related regula- tions in Korea Building Act are reflected in the strategy for the lexical and syntactic design of KBimCode Language; 2) specification of KBimCode based on the context-free EBNF notation is introduced; and evaluation of the language definition is performed. KBimCode is an ongoing project. Together with newly developed rule checking ap- plications, KBimCode will establish automated design quality assess- ment system in Korea.

summary	MOLIT authorised Indoor Spatial Information as Basic spa- tial information in 2013. It became a legal evidence for constructing and managing Indoor Spatial Information. Although it has a little ad- vantage to utilise as service level that Indoor Spatial Information by laser scan or measurement, it has a lot of problems such as consuming many resources, requiring additional progresses for inputting Object Information. In conclusion, it is inefficient to utilise for the mainte- nance and domestic AEC/FM field. The purposes of this study is to output Indoor Spatial Information by operating IFC model which based on open BIM and to improve availability of Indoor Spatial In- formation with data visualisation. The open-sources of IFC Exporter, an inner program of Revit, is used to output Indoor Spatial Infor- mation. Directs 3D Library is also operated to visualise Indoor Spatial Information. It is possible to inter-operate between XML format and the objects of Indoor Spatial Information. It can be utilised in various field as well. For example COBie linkage in facility management, construction of geo-database using air-photogrammetry of UA V , the simulation of large-scale military operations and the simulation of large-scale evacuation. The method that is purposed in this study has outstanding advantages such as conformance with national spatial in- formation policy, high level of interoperability as indoor spatial in- formation objects based on IFC, convenience of editing information, light level of data and simplifying progress of producing information.
