title Exploration of Urban Street Patterns – Multi-Criteria Evolutionary Optimisation Using Axial Line Analysis
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. 695-704
summary In urban design, researchers have developed techniques to automate both the generation and evaluation of urban street patterns. In most cases, these approaches are investigated in isolation from one another. Recently, a number of researchers have attempted to couple these approaches, in order to enable larger numbers of street patterns to be generated and evaluated in an iterative loop. However, to date, the possibility of fully automating the generative-evaluative loop using optimisation algorithms has not been explored. This research proposes an explorative design method in which urban street patterns can be optimised for multiple conflicting performance criteria. The optimisation process uses evolutionary algorithms to evolve populations of design variants by iteratively applying three key procedures: development, evaluation, and feedback. For development, a generative technique is proposed for constructing street patterns. For evaluation, various performance measures are used, including in particular Space Syntax based Axial Line analysis. For feedback, a Pareto-ranking algorithm is used that ranks street patterns according to multiple criteria. The proposed method is demonstrated using an abstract scenario in which orthogonal street patterns are evolved for a small urban area.

title Towards to a Hybrid Model-Making Method based on Translations between Physical and Digital Models - A case study of the freeform architectural design
source M. Haeusler, M. A. Schnabel, T. Fukuda (eds.), Intelligent & Informed - Proceedings of the 24th CAADRIA Conference - Volume 2, Victoria University of Wellington, Wellington, New Zealand, 15-18 April 2019, pp. 561-570
summary The extensive applications of digital models might decrease the capacity of physical model-making for perceptual thinking and enlarge the gap between architects and physical space with limited visual experience. This study aims to propose a reverse process for realizing translations between physical and digital model-making methods from which architects could maximize their initial ideas in conceptual design while allowing for rational digitalization in the detailed design. A review of Reverse Engineering architectural applications is presented and the hybrid method is proposed and examined in a freeform design case. The research shows that in the first translation phase, from handmade physical models to parametric digital models, freeform geometry could be better parameterized in a low degree of deformation based on photogrammetry. Meanwhile, in the second translation phase, from detailed digital models to large-scale physical models, the digitally-driven fabrication could be applied more precisely and automatically based on error handling by 3D laser scanning. Moreover, the process and algorithms developed for the hybrid model-making method indicate the possibility of being applied to further freeform architectural design cases.

title A Visual Landscape Assessment Approach for High-density Urban Development
source Computer Aided Architectural Design Futures 2005 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-3460-1] Vienna (Austria) 20–22 June 2005, pp. 125-134
summary The rapid developments of economy and urbanization bring great pressure to natural environment and resources, which contribute big challenge to sustainable urban development in high-density urban areas like Hong Kong, China and many other Eastern Asia cities. In these areas, protecting natural landscape resources and enhancing visibility to urban spaces and residential zones has become significant in improving the livability of human settlement. This paper presents a new approach in assessing the visual quality in high-density urban environment. The principal methodology is to quantitatively integrate human visual perception parameters with the visible landscape resources' characteristics. GIS is employed as the database and technical platform. A residential development in Hong Kong was used as a case study. The approach provides decision making support to urban planning, site layout design, and estate management during the early stage of the schematic design/planning process.

title CAD Study in Visual Analysis of the Visual Sustainability for China Urban Natural Landscape Planning
source Chinese University of Hong Kong
summary In this thesis a GIS-based CAD system prototype of evaluating visual quality of urban natural landscape environment is presented. This prototype is an indispensable component of the integrative Visual Sustainability research, and offers a calculable and visualizable technique to urban visual natural landscape assessment. This scientific method provides precise data to estimate the visibility of natural landscape in urban construction actuality. Furthermore, it can also work out supporting information for maintaining and protecting valuable visual landscape resources in further planning. Introduction of this methodology intends to improve the natural landscape cooperation in China urban planning through visual protection. Combining with popular CAD software such as AutoCAD and Microstation, the research team uses ArcView GIS software and its 3D Analyst extension to accomplish a set of research procedure, which includes data modification, model making, viewshed and view sensibility analysis. In addition, this system can create simultaneous 3D scenes or hire other information media as reference tools for professional analysis, design consultation and intercommunication. The core technologies of this proposed system are viewshed calculation and overlay analysis. In viewshed analysis, human visual characteristics are simulated by a series of ergonomics parameters of viewpoints. Viewshed of each viewpoint can be calculated into vector data and mapped by polygons identifying which region is visible and which is not. Overlay function of the proposed system is used in visual sensibility analysis to achieve the division of higher visual sensible area which indicates the common visible area from different viewpoints. Additionally, viewshed maps and visual sensibility results can add more information to mark out the areas that can satisfy certain visual parameters such as appropriate visual angle or visual distance. These overlaying results can visualized the visible areas into hierarchical visual perception quality categories in order to define the visual landscape significance of particular planning regions. A case study was operated to evaluate this system. The case is in Zhongshan city, Guangdong Province of China. Jinzishan hill region is the study site that picked by collaborating discussion of research team and the local government. It is located on the edge of urban built-up area. Jinzishan massif is the prominent landscape element of the surrounding environment. There are three topics in Jinzishan visual perception in this paper. The first topic is the visual quality evaluation of the intersections of its surrounding road system. The second is the integrated visual perception of two main roads called Qiwandao and Bo’ailu. Finally is the analysis of the hill skyline visual quality in surrounding area. The analysis results in GIS vector data can be converted into popular data format and combined with other spatial information for practical application. And comments for future urban planning are collected and analyzed by professional responses to the computer-generated information investigation.

title SpaceCore: Metadata for Retrieving Spatial Information in Architecture
source Thresholds - Design, Research, Education and Practice, in the Space Between the Physical and the Virtual [Proceedings of the 2002 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-11-X] Pomona (California) 24-27 October 2002, pp. 197-215
summary This research investigates the spatial information retrieval in architecture focused on constructingefficient metadata that is crucial for data retrieval. Generally speaking, metadata is ‘structured dataabout data’ to describe the resources especially in a digital method. In this research, metadata is a sortof data object to be used in searching spatial information, such as describing a raw spatial data objectnot only as attribute data but also as content, structurally and semantically. There are two issues thatmotivate this research; 1) the materialization of the intangible space as a data object, and 2) thecontent-based information retrieval. In the viewpoint of content-based retrieval, we analyze spatialinformation on the apartment unit floor plan common in Korea. Then we extract the metadata items in astructured manner. To manage the items efficiently, we develop a data model for spatial informationaccording to the concept of “Structured Floor Plan”. For exploiting the metadata, this research showsseveral possibilities of query operations to present a set of sample queries about L-D-K(Living room -Dining room – Kitchen). Implementation of the prototype system is divided into three parts: 1) amodeling module, Vitruvis; 2) an indexing module, SpaceCore; and 3) a browsing module.

title SpaceScope: Spatial Content-Based Retrieval of Architectural Floor Plans
source Digital Design - Research and Practice [Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1] Tainan (Taiwan) 13–15 October 2003, pp. 53-62
summary This research investigates spatial information retrieval in architecture, based on an efficient metadata that is crucial for content-based retrieval. SpaceCore is the metadata schema for spatial information on a floor plan implemented with RDF (Resource Description Framework). To generate metadata, we analyse the factors of spatial information, and then construct a data model containing the content and structure of spatial information. To exploit the metadata, we suggest various query operations with possible predicates and interfaces. SpaceScope, the spatial information retrieval system, consists of three modules: an input data module, a query module, and a browse module. As to implementation, we have already developed the real time plan-structuring system, called “Vitruvius”, as an inputting and modelling data module (using C++). Based on the database, the system performs the similarity analysis and then evaluates the alternative plans with the retrieval goals. At the end of the paper we discuss the potential of SpaceScope in the schematic design stage of the architectural design process, possibly improving and triggering the designer’s conceptual approach against a logical background and facilitate rapid decision-making after full consideration.

title SpaceScope: Developing a Spatial Information Retrieval System - Focused on Apartment Unit Floor Plans -
source Yonsei University, Dept. of Housing & Interior Design
summary This research investigates the spatial information retrieval (IR) in architecture focused on constructing efficient metadata that is crucial for data retrieval. Generally speaking, metadata is ‘structured data about data’ to describe resources especially in a digital format. In this research, metadata is a sort of data object to be useful in searching spatial information. Metadata is also used to describe raw spatial data object as not only attribute data but also content structurally and semantic ally. There are two issues that motivate this research; 1) what is the spatial information – that materializes the intangible space as a data object, and 2) how we can search the information efficiently – the content-based information retrieval. Although knowledge of a building’s spatial content is most important in architecture, there has been no logical method to manage it.

From the viewpoint of content-based retrieval, the researcher analyzes spatial information of a floor plan, with a focus on the apartment unit floor plan common in Korea. Then the metadata items are extracted in a structured manner. To manage the items efficiently, the researcher develops a data model for spatial information according to the concept of the “Structured Floor Plan”. The main object of content to retrieve is a spatial network that consists of nodes of spaces and their linkages. There are two ways to organize the metadata: the traditional index files and the RDF (Resource Description Framework). While the index files are still efficient with computability, the RDF applies greater options to retrieve, such as fuzzy predicates, semantic predicates, and so on. To exploit the metadata, this research shows several possibilities of query operations that present a set of sample queries about L-DK(Living room – Dining room – Kitchen). Implementation of the prototype system is divided into three parts: 1) a modeling module using Vitruvius; 2) an indexing module using MS SQL Server? 2000 in conjunction XML; and 3) a browsing module using the SpaceScope browser.

The future works may consider XML-based databases and a knowledge based query language, such as RQL/XQL, working on such databases. The more specific domain knowledge is involved, the more practical systems would be. Even in architecture, there may be a diverse range of domain knowledge, such as design, building performance, facility management, energy management, post occupied evaluation, historical research, and so on. Also the issue of interface should be investigated in depth, so that it will be adequate to the needs of the architectural field.

summary This paper presents an improvement of the original openness ratio concept, which has been formulated as an integrated index for early-stage urban open space planning and design support. The ‘greenscape index’ is a rating system which quantitatively integrates human visual perception with the visible landscape resources to evaluate the visual quality of open space vision within high-density urban environment. This new index is expected to provide more comprehensive environmental performance consideration criteria for urban planning and design. The research team also discusses the potential of the introducing this index to assess both psychological preference and physical form of urban open spaces. The new concept also has shown its feasibility on integrating key environmental considerations in visual sensitivity, urban wind, urban noise and solar heat gain into simple massing study which is applicable in the preliminary planning stage.

title A shape grammar for teaching the architectural style of the Yingzao Fashi
source Massachusetts Institute of Technology, Department of Architecture
summary The Yingzaofashi [Building standards] is a Chinese building manual written by Li Jie (d. 1110) and published in 1103. I present a shape grammar for teaching the architectural style - the language of designs - described in this manual. This grammar is distinguished by two objectives, and the technical means used to accomplish them. First, the grammar is for teaching. Usually, the author of a grammar of a style aims to generate all and only the designs in the language. To do this, he not only writes the grammar, but also judges whether the designs it generates are members of the language. In the Yingzaofashi grammar, on the other hand, I want to generate all and more than the designs in the language. It is then the student who evaluates the designs - does this design belong to the language? - and adjusts the grammar accordingly. Thus the student participates actively in defining the language of designs, and learns that style is a human construct. Second, the grammar is designerly. As already observed, most authors of style grammars focus on the language of designs; they do not consider how to structure the user's interaction with the grammar. By contrast, I consider explicitly what the user decides and when he decides it, and organize the grammar accordingly. In other words, I consider process as well as products. The grammar exploits several technical devices for the first time: the design as an n-tuple of drawings, descriptions, and other elements; the generation of descriptions in the n-tuple; and techniques that are made possible by these devices.

summary Heating, ventilation and air-conditioning system plays a key role in shaping the built environment. The effective and efficient HVAC operations not only achieve energy savings but also create a more comfortable environment for occupant indoors. Since current HVAC systems with fixed schedules cannot guarantee the operation with high energy efficiency and provision of comfortable thermal environment for occupants, it is of great importance to develop new paradigm of HVAC system framework, especially in the open-plan office environment so that everyone could work under their preferred thermal environment. Moreover, compared to environment-related factors to thermal comfort, sensing systems for occupant-related factors such as clothing insulation, metabolic rate, skin temperature have not had standardized yet and most of sensing systems for occupant-related factors may either result in privacy issue or are too intrusive. Hence, it is necessary to develop a new non-intrusive and less private sensing framework for monitoring individual thermal comfort in real-time. Therefore, this paper proposes an integrative comfort-based personalized cooling system with the operation of the centralized systems in office buildings. The results show that such integrative and interactive HVAC system for workplaces has advantages over thermal comfort improvements and energy savings.

summary The paper documents the design and development of an additive manufacturing process based on stone aggregates. Unlike conventional 3D printing technologies which target miniaturization of the material grain and deposition layers to achieve as high resolution as possible, our process deploys sizeable and randomized grains of stone. The objective of this is to leverage between physical scale of the particulate and time it takes to produce large enough artefacts, fast enough to potentially evoke spatial qualities. Perhaps unavoidably, due to its materiality, the process revisits one of the most archaic methods of building technology, namely masonry, and suggests for a unique digital perspective for structures and landscapes made from stone.

title Performance Based Planning for High Density Urban Habitation
source Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 515-522
summary In Hong Kong, about 22% of the total territory‘s area can be classified as built-up area and potential development area. Only 6% of this area is allocated to district and local open space for the 6.8 million populations, i.e. 2m2 per person. Sensible planning of the limited area to enhance the livability and environmental quality hence become a challenging issue for quality urban living of the mass population. However, considering the dynamic relationship of the different performance criteria in the hyper-dense urban environment, one needs to assess various environmental criteria to carry out a balanced planning. Meanwhile, effective tools to evaluate and manage the inter-relationship of these criteria, or indexes for integrated issues indication are not readily available that a reasonable planning is not always easy to achieve. In this paper, the „openness ratio“ concept is introduced for open space planning to provide an integrated index for early stage of planning and design. The new index is expected to provide a comprehensive rating system in considering the environmental performance of open area. It helps to highlight the potential problems in planning or site layout and support the integrated thinking of the four key components: visual sensitivity, urban wind, urban noise and solar heat gain. The concept has shown to be feasible on simple massing study which is applicable in the preliminary planning stage.
