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.

title	Genetic Algorithms in Support of Creative Architectural Design
doi	https://doi.org/10.52842/conf.ecaade.1999.645

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.

source	Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 305-310
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 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
doi	https://doi.org/10.52842/conf.caadria.2018.2.133
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
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.

summary	The complexity of the wall form affects the acoustics of the space. In this study, the effect of the complex form walls produced by nCloth dynamic simulation on the acoustics of an office space was investigated. In this research, reverberation time and Speech Transmission Index (STI) values of the pilot office space with one wall having complex form and the office space with all of the walls as flat were measured by acoustic simulation. As a result of the comparison, it has been found that, within speech intelligibility and reverberation time, the acoustics of the space with one wall having complex form is better than the acoustics of the space with all the walls as flat.

summary	This paper reports an investigation into the degree of con- sistency between three different methods of sound performance evalu- ation through studying the performance of a built project as a case study. The non-controlled office environment with natural human speech as a source was selected for the subjective experiment and ODEON room acoustics modelling software was applied for digital simulation. The results indicate that although each participant may in- terpret and perceive sound in a particular way, the simulation can pre- dict this complexity to some extent to help architects in designing acoustically better spaces. Also the results imply that architects can make valid comparative evaluations of their designs in an architectur- ally intuitive way, using architectural language. The research acknowledges that complicated engineering approaches to subjective analysis and to controlling the test environment and participants is dif- ficult for architects to comprehend and implement.

summary	The following paper deals with a performance-driven morphogenetic design task to improve the conditions of room acoustics, using as a case study the material laboratory of the School of Architecture at Federico Santa Maria University of Technology. Combining contemporary Parametric Modeling techniques and a Performance- Based approach, an automatic generative system was produced. This system generated a modular acoustic ceiling based on Helmholtz Resonators. To satisfy sound absorption requirements, acoustic knowledge was embedded within the system. It iterates through a series of design sub-tasks from Acoustic Simulation to Digital Fabrication, searching for a suitable design solution. The internal algorithmic complexity of the design process has been explored through this case study. Although it is focused on an acoustic component, the proposed design methodology can influence other experiences in Parametric Design.

summary	This research investigates the effect of curvature, at a variety of scales, on the acoustic properties of glass. Plate glass, which has predictable and uniform acoustically reflective behavior, can be formed into curved surfaces through a combination of parametrically-driven auxetic pattern generation, CNC water-jet cutting, and controlled heat forming. When curved, plate glass becomes “activated” and complex acoustically-diffusive behavior emerges. The parametrically-driven auxetic perforation pattern allows the curvature to be altered and controlled across a formed pane of glass, and a correlation is demonstrated between the level of curvature and the extent of acoustically diffusive behavior. Beyond individual panels, curved panes can be aggregated to extend acoustic influence to the entire interior room condition, and the pace at which acoustic energy is distributed can be controlled. In this work the parameters surrounding the controlled slumping of glass are described, and room-sized formal and acoustic effects are studied using wave-based acoustic simulation techniques. This paper discusses the early stages of work in progress.

summary	In this research project we explore the defined design and application of digitally fabricated wall panels for room-acoustical architectural interventions. In Particular, we investigate the room-acoustical criteria applying to everyday used spaces. We present a digital design and fabrication process developed to create non-standardised panels and two case studies which apply this process on the acoustical improvement of a specific room situation. Our aim is to find correlations between digitally fabricated surface structures and sound- aesthetical characteristics, in order to utilise these for the architectural design.

summary	The computer holds a great potential to break down the barriers between architecture and the technical aspects relating to architecture, thus supporting innovative architecture with an inner correspondence between form and technique. While the differing values in architecture and technique can seem like opposites, the term tectonics deals with creating a meaningful relationship between the two. The aim of this paper is to investigate what a digital tectonic tool could be and what relationship with technology it should represent. An understanding of this relationship can help us not only to understand the conflicts in architecture and the building industry but also bring us further into a discussion of how architecture can use digital tools. The investigation is carried out firstly by approaching the subject theoretically through the term tectonics and by setting up a model of the values a tectonic tool should encompass. Secondly the ability and validity of the model are shown by applying it to a case study of Jørn Utzon’s work on Minor Hall in Sydney Opera House - for the sake of exemplification the technical field focused on in this paper is room acoustics. Thirdly the relationship between the model of tectonics and the case will be compared and lastly a discussion about the characteristics of a tectonic tool and its implications on digital tectonic tools will be carried out.

summary	The sometimes complex architectural shape of halls creates modelling difficulties as the simulation computing systems need plane surfaces. In order to approach a perfect shape of curved surfaces, a big number of facets is necessary. This poses, as a consequence, computer memory problems which is the case of the horse shoe shaped Opera House with its richly decorated columns, balconies, etc. This paper compares the acoustical measurement results and the calculation results of a computer simulation software applied on several models (from the most simple till the most complex ones) of the Grand Theatre of Bordeaux.

summary	This paper explores the application of agent-based modeling techniques to the domain of acoustics design. Concepts derived from Stigmergy, which is a class of mechanisms that mediate interactions between social organisms, are applied to a custom implementation of a raytracing based acoustics simulator. Rays are given the agency of changing the geometric and material properties of the surfaces they come in contact with during the raytracing phase. The acoustic simulation process is an active one, where the modeled room environment is adapted while being evaluated. Given performance criteria as input, the simulation process is applied to an auditorium example. The auditorium is adapted and its eventual emergent design has improved acoustic performance. It is hoped that this work will demonstrate the potential of coupling multi-agent systems with simulation processes in order to create new design tools.

summary	Since not all architectural projects can be involved in performance design calculations or optimizations, this study aims to reduce user technical barriers and enhance the visualization of the evaluation process. This paper introduces a parametric approach to room acoustics simulation, offering an interactive interface for modeling and simulation. By using Rhino-Grasshopper as a real-time ray tracing interface, both the Image Source Method (ISM) and Early Scattered Method (ESM) are employed for ray particle rebound tracking and analysis. The feasibility and analysis of spatial acoustic assessment tools are explored through the combination of data visualization and open-source parameter design meth. This research diversifies spatial models using various modeling tools like Revit, ArchiCAD 25, Rhinoceros 3ds, and SketchUp. This approach enables the evaluation of the effects and disparities caused by different modeling systems on simulation calculations. Furthermore, this paper also highlights the potential optimization of the Building Information Modeling (BIM) design workflow process. The results underscore the relationship between improved simulation accuracy and the utilization of numerical calculations, referencing benchmark simulation software ODEON for data comparison and review.

title	Geometric Modeling intThe Simulation of Fire - Smoke Spread in Buildings
source	II Seminario Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings / ISBN 978-97190-0-X] Mar del Plata (Argentina) 9-11 september 1998, pp. 438-445
summary	Since the performance simulation of buildings, such as fire/smoke spread, energy loss/gain, acoustics, etc. greatly rely on building geometry, the way the physical environment is modeled can substantially effect the reliability of the predictions made by such simulations. Most computer models that simulate fire and smoke spread in buildings limit the computer representation of the building to simpler geometries and define rooms as rectangular spaces or as spaces with uniform crossections. Such a definition does not account for the variety of building elements that can exist in a building such as large overhangs, half height walls, etc. Existing simulations are typically developed as mathematical models and use the principles of thermodynamics to represent the spread of the elements of fire through space over a given time period. For example, in zone models each room is defined as a two tier space with heat and smoke exchange between lower and upper tiers as the fire progresses. On the other hand, field models divide the space into small contiguous units where thermodynamic state of each unit is calculated as the simulated fire progresses. Dynamic processes such as fire and smoke spread must recognize both intangible (i.e. voids) and tangible (i.e. solids such as walls, balconies, ceiling, etc.) architectural entities. This paper explores the potential of solid modeling techniques in generating geometric definitions for both solid and void architectural entities that can interact With mathematical models of fire/smoke spread in buildings. The implications of cellular spatial partitioning techniques for zone or field models of fire/smoke spread are investigated, and the methods of creating cellular decomposftion models for architectural spaces as well as for spatial boundaries such as walls are explored. The size of each cellular partition, i.e. the resolution of the partition, and the material and heat transfer attributes of each cell were found to be very critical in modeling the spread fire through voids as well as through solids in a building.

summary	The paper investigates and assesses different room acoustics software and the opportunities they offer to engage in parametric acoustics workflow and to influence architectural designs. The first step consists in the testing and benchmarking of different tools on the basis of accuracy, speed and interoperability with Grasshopper 3d. The focus will be placed to the benchmarking of three different acoustic analysis tools based on raytracing. To compare the accuracy and speed of the acoustic evaluation across different tools, a homogeneous set of acoustic parameters is chosen. The room acoustics parameters included in the set are reverberation time (EDT, RT30), clarity (C50), loudness (G), and definition (D50). Scenarios are discussed for determining at different design stages the most suitable acoustic tool. Those scenarios are characterized, by the use of less accurate but fast evaluation tools to be used in early design stages, or by more accurate but slower tools for later-stage design stage detailing and delivery phases.
