summary	The functions supported by commercial CAAD software are drawing, construction and presentation. Up to now few programs supporting the creative part of architectural problem solving have become available. The grand hopes of symbolic AI to program creative architectural design have been disappointing. In the meantime, methods called referred to as New AI have become available. Such methods includegenetic algorithms (GA). But GA, though successfully applied in other fields of engineering, still waits to be applied broadly in architectural design. A main problem lies in defining function in architecture. It is much harder to define the function of a building than that of a machine. Without specifying the function of the artifact, the fitness function of the design variants participating in the survival game of artificial evolution remains undetermined. It is impossible to fully specify the fitness function of architecture. The approach presented is one of circumventing a full specification through dividing labor between the GA software and its user. The fitness function of architectural ground plans is typically defined in terms only of the proportions of the room to be accommodated and certain topological relations between them. The rest is left to the human designer who interactively intervenes in the evolution game as displayed on the screen.

summary	The Department of Real Estate and Project Management (BMVB) of the Faculty of Architecture at the Delft University of Technology has been working closely with Professor Spiro N. Pollalis of Harvard University, Graduate School of Design in Cambridge, USA since 1991. His case-based interactive seminars about the management of the design & construction process have been highly appreciated by many generations of students. In Spring 2000, Pollalis suggested to extend the scope of his involvement by introducing a remote teaching component, the subject of his research in the last few years. As Information and Communication Technology (ICT) in the Design and Construction Industry is part of his lectures, it was appropriate to provide the students with a first hand experience on the subject. In the following experiment, the teacher would remain in his office at Harvard while the interactive work and discussion sessions with 130 students in a full lecture room would take place in Delft as planned. The consequences this experiment has had for the course, for the techniques and facilities used, how teachers and students experienced these, and which conclusions and recommendations can be made, are the topics of this paper.

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.

title	Virtual situation rooms: connecting people across enterprises for supply-chain agility
source	Computer-Aided Design, Vol. 32 (2) (2000) pp. 109-117
summary	Agility and time-based manufacturing are critical success factors for today's manufacturing enterprise. To be competitive, enterprises must integrate their supply chains moreeffectively and forge close memberships with customers and suppliers more quickly. Consequently, technologies must be developed that enable enterprises to respond toconsumer demand more quickly, integrate with suppliers more effectively, adapt to market variations more efficiently and evolve product designs with manufacturing practicesmore seamlessly. The mission of the Extended-Enterprise Coalition for Integrated Collaborative Manufacturing Systems coalition is to research, develop, and demonstratetechnologies to enable the integration of manufacturing applications in a multi-company supply chain planning and execution environment. We believe real-time andasynchronous collaboration technology will play a critical role in allowing manufacturers to increase their supply chain agility. We are realizing our efforts through our VirtualSituation Room (VSR) technology. The primary goal of the VSR technology is to enhance current ad-hoc, limited methods and mechanisms for spontaneous, real-timecommunication using feature-rich, industry standards-based building blocks and network protocols. VSR technology is being designed to find and engage quickly all relevantmembers of a problem solving team supported by highly interactive, conversational access to information and control and enabled by business processes, security policies andtechnologies, intelligence, and integration tools.

summary	The paper presents the findings of 4 years of experimentation in the use of compressed videoconferencing in collaborative virtual design studios. Based on these findings, the authors elaborate on the development of a new videoconferencing interface especially conceived for mediation between distant design studios: “The Infinity Room”. The Infinity Room is a design studio space containing a floor-to-ceiling rear projection screen wall that conceals a dark room equipped with video cameras an video projectors that reproduce, on one-on-one scale, the images captured in a similar installation at a remote location. The paper describes the design parameters used in the development of the Infinity Room and elaborates on the technology that makes it feasible. Initial implementation plans are described.

summary	The paper presents the findings of three years of experimentation in the use of compressed videoconferencing in international virtual design studios. Based on these findings, the authors elaborate on the development of a new videoconferencing interface: "The Infinity Room". The Infinity Room is a design studio space containing a floor-to-ceiling rear projection screen wall that conceals a dark room equipped with 5 video cameras and 4 video projectors that reproduce, on one-to-one scale, the images captured in a similar installation at a remote location. Operationally, the video cameras feed a computer that eliminate image redundancies, codes all the sources into a single entity and sends it as a compressed video signal to a remote computer that decodes and decompresses the images for synchronized delivery through the video projectors. The tiling effect of 4 synchronized and fully interactive video images creates the illusion of an adjacent room. The paper describes the design parameters used in the development of the Infinity Room and elaborates on the technology that makes it feasible. Requirements and constraints on physical space, hardware, software, and networking are discussed. The paper ends with conclusions that highlight the technical feasibility of building a small-scale prototype.

title	A Parametric Approach for Ascertaining Daylighting in Unit Offices with Perforated Solar Screens in Daylight Climate of Northeast China
source	T. Fukuda, W. Huang, P. Janssen, K. Crolla, S. Alhadidi (eds.), Learning, Adapting and Prototyping - Proceedings of the 23rd CAADRIA Conference - Volume 2, Tsinghua University, Beijing, China, 17-19 May 2018, pp. 133-142
doi	https://doi.org/10.52842/conf.caadria.2018.2.133
summary	Perforated solar screens (PSS) are broadly adopted, providing obvious control over daylight, and also affecting heating and cooling loads. In this paper, a parametric information model is proposed for analyzing daylight of unit offices with PSS, aiming to ascertain the impact exerted by PSS design variables on daylighting, i.e. perforation size, porosity, overhanging distance and perforation width/height ratio. As the results uncover, in comparison to cases of no shading, PSS can reduce overlighting possibility and increase quantity of useful daylight percentage in the near and middle zones of room, but decrease illuminance in the far zone. Porosity is the factor of most significance with UDI100-2000 inclining maximally by 65%. Overhanging distance and width/height ratio rank behind and larger overhanging distance and ratio at 1 are recommend with more useful daylight in the maximum range. Perforation size is of the least importance.

title	Hearing Architectural Design: Simulation and Auralization for Generating Better Acoustic Spaces
source	International Conference on Generative Art
summary	This paper with demonstration is devoted to revealing and establishing the relationship between space and sound through computational acoustic analysis, simulation and electronic synthesis of audible sound. Based on science of acoustics and computing technology, acoustic effect of an architectural 3-D design can be analyzed and the resulted sound in space can be synthesized and predicted accordingly and being heard. Auralization refers to this process of acoustic analysis, sound synthesis and audio presentation of the result in the form of audible sound. Design alternatives can be experimented until satisfactory acoustic effect is achieved. Traditionally, designers rely on some minimum and vague understanding or specialists’ experiences to predict and design for a desirable sound behavior in spaces. Most likely acoustic design and analysis are seen as a luxury remedy only affordable in large-scale theatres and concert halls. The recent available PC based auralization tools brought significance in both in terms of new knowledge towards the science and art of architectural acoustics and the methods and practice in the design process. The examples demonstrated in the presentation will indicate that the auralization technology make it possible for the designers, consultants, end users or potential occupants to examine and evaluate the performance of different designs by hearing it directly before an informed decision can be made. The case studies also illustrated that the auralization is a powerful tool for general public with common building types to uncover everyday acoustic problems that have been constantly harming their well being and would otherwise be undetected.
