title SHARED SPACE’ AND ‘PUBLIC SPACE’ DIALECTICS IN COLLABORATIVE ARCHITECTURAL DESIGN.
source Proceedings of Collaborative Decision-Support Systems Focus Symposium, 30th July, 2002; under the auspices of InterSymp-2002, 14° International Conference on Systems Research, Informatics and Cybernetics, 2002, Baden-Baden, pg. 27-44.
summary The present paper describes on-going research on Collaborative Design. The proposed model, the resulting system and its implementation refer mainly to architectural and building design in the modes and forms in which it is carried on in advanced design firms. The model may actually be used effectively also in other environments. The research simultaneously pursues an integrated model of the: a) structure of the networked architectural design process (operators, activities, phases and resources); b) required knowledge (distributed and functional to the operators and the process phases). The article focuses on the first aspect of the model: the relationship that exists among the various ‘actors’ in the design process (according to the STEP-ISO definition, Wix, 1997) during the various stages of its development (McKinney and Fischer, 1998). In Collaborative Design support systems this aspect touches on a number of different problems: database structure, homogeneity of the knowledge bases, the creation of knowledge bases (Galle, 1995), the representation of the IT datum (Carrara et al., 1994; Pohl and Myers, 1994; Papamichael et al., 1996; Rosenmann and Gero, 1996; Eastman et al., 1997; Eastman, 1998; Kim, et al., 1997; Kavakli, 2001). Decision-making support and the relationship between ‘private’ design space (involving the decisions of the individual design team) and the ‘shared’ design space (involving the decisions of all the design teams, Zang and Norman, 1994) are the specific topic of the present article.

Decisions taken in the ‘private design space’ of the design team or ‘actor’ are closely related to the type of support that can be provided by a Collaborative Design system: automatic checks performed by activating procedures and methods, reporting of 'local' conflicts, methods and knowledge for the resolution of ‘local’ conflicts, creation of new IT objects/ building components, who the objects must refer to (the ‘owner’), 'situated' aspects (Gero and Reffat, 2001) of the IT objects/building components.

Decisions taken in the ‘shared design space’ involve aspects that are typical of networked design and that are partially present in the ‘private’ design space. Cross-checking, reporting of ‘global’ conflicts to all those concerned, even those who are unaware they are concerned, methods for their resolution, the modification of data structure and interface according to the actors interacting with it and the design phase, the definition of a 'dominus' for every IT object (i.e. the decision-maker, according to the design phase and the creation of the object). All this is made possible both by the model for representing the building (Carrara and Fioravanti, 2001), and by the type of IT representation of the individual building components, using the methods and techniques of Knowledge Engineering through a structured set of Knowledge Bases, Inference Engines and Databases. The aim is to develop suitable tools for supporting integrated Process/Product design activity by means of a effective and innovative representation of building entities (technical components, constraints, methods) in order to manage and resolve conflicts generated during the design activity.

title ADELINE, an Integrated Approach to Lighting Simulation
source Proceedings of Right Light 4, 4th European Conference on Energy-Efficient Lighting, pp.99-103
summary The use of daylighting and artificial lighting simulation programs to calculate complex systems and models in the design practice often is impeded by the fact that the operation of these programs, especially the model input, is extremely complicated and time-consuming. Programs that are easier to use generally do not show the calculation capabilities required in practice. A second obstacle arises as the lighting calculations often do not allow any statements regarding the interactions with the energetic and thermal building performance. Both problems are mainly due to a lacking integration of the design tools of other building design practitioners as well as due to insufficient user interfaces. The program package ADELINE (Advanced Daylight and Electric Lighting Integrated New Environment) being available since May 1996 as completely revised version 2.0 presents a promising approach to solve these problems. This contribution describes the approaches and methods used within the international project IEA Task 21 for a further development of the ADELINE system. Aim of this work is a further improvement of user interfaces based on the inclusion of new dialogs and on a portation of the program system from MS-DOS to the Windows NT platform. Additional focus is laid on the use of recent developments in the field of information technology and experiences gained in other projects on integrated building design systems, like for example EU-COMBINE, in a pragmatical way. An integrated building design system with open standardized interfaces is to be achieved inter alia by using ISOSTEP formats, database technologies and a consequent, object-oriented design.

title Building Design Advisor: automated integration of multiple simulation tools
source Automation in Construction 6 (4) (1997) pp. 341-352
summary The Building Design Advisor (BDA) is a software environment that supports the integrated use of multiple analysis and visualization tools throughout the building design process, from the initial, conceptual and schematic phases to the detailed specification of building components and systems. Based on a comprehensive design theory, the BDA uses an object-oriented representation of the building and its context, and acts as a data manager and process controller to allow building designers to benefit from the capabilities of multiple tools. The BDA provides a graphical user interface that consists of two main elements: the Building Browser and the Decision Desktop. The Browser allows building designers to quickly navigate through the multitude of descriptive and performance parameters addressed by the analysis and visualization tools linked to the BDA. Through the Browser the user can edit the values of input parameters and select any number of input and/or output parameters for display in the Decision Desktop. The Desktop allows building designers to compare multiple design alternatives with respect to multiple descriptive and performance parameters addressed by the tools linked to the BDA. The BDA is implemented as a Windows®-based application for personal computers. Its initial version is linked to a Schematic Graphic Editor (SGE), which allows designers to quickly and easily specify the geometric characteristics of building components and systems. For every object created in the SGE, the BDA activates a Default Value Selector (DVS) mechanism that selects `smart' default values from a Prototypes Database for all non-geometric parameters required as input to the analysis and visualization tools linked to the BDA. In addition to the SGE that is an integral part of its user interface, the initial version of the BDA is linked to a daylight analysis tool, an energy analysis tool, and a multimedia, Web-based Case Studies Database (CSD). The next version of the BDA will be linked to additional analysis tools, such as the DOE-2 (thermal, energy and energy cost) and RADIANCE (day/lighting and rendering) computer programs. Plans for the future include the development of links to cost estimating and environmental impact modules, building rating systems, CAD software and electronic product catalogs.

summary So far yet, even the most advanced technology has not been able to substitute a human, his thoughts, feelings, dreams, longings, visions. It can though, removing need for all kind of effort from our everyday life, surrounding a human with unprecedented comfort, create feeling of peace and security. Task of a computer is to provide assistance, helping in calculations, forming of refined solids, It contains a compendium of knowledge and memory - but not creative skills. So far it's only a machine, with help of which a possibility of creative expression is expanded. It only can solve problems for a human faster and more efficient way, does not have the ability to describe (formulate) problems. Even while providing a support, does it do that honestly? It means, does it support us in those of our doings where we truly need it? Computers have enormous possibilities of use that are not exploited sufficiently and all the time new generations of yet quicker machines with unbelievable power are being created. Every new type of computer appears to be obsolete and insufficient within a few months. Insufficient for what?

title Case study - Multiprofessional
source Automation in Construction 6 (1) (1997) pp. 51-57
summary IT is just a tool, but the most powerful one ever to be offered to us. This case study deals with the areas at which IT can be targeted within the Building Design Partnership. Firstly, should anything be done and if so, what criteria should be used to choose the priorities? A SWOT analysis is one way way to identify goals. Strengths/weeknesses, opportunities/threats are the positive/negative pairs. We have to build our strength and perceive and take opportunities while at the same time countering weaknesses and threats. It is a threat that the industry sets a moving target of IT capability without wanting to meet its cost. It is an opportunity that only a few practices will be at the leading edge and that they will secure the key projects. IT could help us to overcome technical weaknesses and liability and reduce staff and premises costs. It could also increase our exposure to fixed capital costs in a cyclical business. IT could increase the success of integrated practice or it could make it easier for separate firms. We believe the likelihood is that IT will do as it has for financial services and favour the large, multi-national, well prepared and technologically advanced firms. New services will emerge and become assential and will separate the `sheep from the goats.'

title Wireless communication and computing at the construction jobsite
source Automation in Construction 7 (4) (1998) pp. 327-347
summary For many years, the walkie-talkie has been synonymous with the construction industry. During jobsite project execution, there are three variables which can either hinder or facilitate successful results, namely, quality, quantity, and timing of information. Wireless data communications technology is capable of delivering just-in-time information within the `last mile' between the trailer and a desired location on the jobsite. This paper reports on a study which surveyed information needs at the jobsite, emerging wireless data communications technology, and assessed the extent to which wireless data technology can fulfill the information needs of the jobsite [J.M. de la Garza, I. Howitt, Wireless communication and computing at the jobsite, Research Report 136-11, Construction Industry Institute, Austin, TX, 1997]. We have organized jobsite information needs into the following ten categories: (a) requests for information, (b) materials management, (c) equipment management, (d) cost management, (e) schedule and means and methods, (f) jobsite record keeping, (g) submittals, (h) safety, (i) QC/QA, and (k) future trends. Each category was analyzed in terms of its appropriateness to take advantage of wireless technology. The four formats considered to transmit information wirelessly were: (a) live voice, (b) live video, (c) batched data, and (d) live data. Current wireless communication technology has been classified into the following five classes: (a) circuit-switched wireless data systems, (b) packet-switched wireless data systems––this class was further subdivided into specialized mobile radio systems and cellular digital packet data systems, (c) wireless local area networks, (d) paging systems, and (e) satellite-based data communications. A primer for wireless communications covering both fundamental and advanced communications concepts has also been included to enable a better understanding of the issues involved in making trade-offs while configuring a wireless jobsite communication system. The example presented in this paper shows how a contractor can define a subset of information needs by choosing from those already articulated herein and determine if a given wireless technology should even be considered as a viable way of meeting the information needs that such company has.

title An integrated approach to design and engineering of intelligent buildings--The Intelligent Workplace at Carnegie Mellon University
source Automation in Construction 6 (5-6) (1997) pp. 401-415
summary In the past few years, there have been significant advances made in the design and engineering of "intelligent" workplaces, buildings that not only accommodate major advances in office technology but provide better physical and environmental settings for the occupants. This paper will briefly present recent approaches to the creation of innovative environments for the advanced workplace. The architectural and engineering advances demonstrated in Japan, Germany, North America, the United Kingdom, and France can be summarized in four major system categories: (1) enclosure innovations including approaches to load balancing, natural ventilation, and daylighting; (2) heating, ventilation and air-conditioning (HVAC) system innovations including approaches to local control and improved environmental contact; (3) data/voice/power "connectivity" innovations; and (4) interior system innovations, including approaches to workstation and workgroup design for improved spatial, thermal, acoustic, visual, and air quality. In-depth international field studies of over 20 intelligent office buildings have been carried out by a multidisciplinary expert team of the Advanced Building Systems Integration Consortium (ABSIC) based at Carnegie Mellon University. ABSIC is a university-industry-government partnership focused on the definition and development of the advanced workplace. The ABSIC field team evaluated the component and integrated system innovations for their multidimensional performance qualities, through expert analysis, occupancy assessments, and field diagnostics. Based on the results of the case studies and building on the most recent technological advances, the ABSIC team developed the concepts for the Intelligent Workplace, a 7000 square foot living laboratory of office environments and innovations. This project is now under construction at Carnegie Mellon University and its features are discussed in the second section of this paper.

source CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 917-926
summary Many of the emblematic buildings constructed at present shows many formal and technological innovations that have not been satisfactorily resolved by the existing CAAD software. Frank 0. Gehry's Guggenheim Museum in Bilbao is a good example of architecture whose shapes and design are very advanced from the concepts and tools used by CAAD. The search for new creative resources, from the educational and professional point of view, must be a priority. This will be the only way to get that CAAD contributes essentially in the process of architectural innovation, instead of merely being a reproduction tool. From this viewpoint the computer exploration of the three dimensional form is presented in here. The concept of abstract art, that has been successfully applied to painting and sculpture in this century is used as a way to experiment, design and create architecture. This paper juxtaposes three approaches, three different ways of understanding the abstract character, with the purpose to create new objects and environments, which are exclusively characteristic for computer space. This juxtaposition shows how creative and innovative activities in the field of CAAD can be developed using different intellectual bases: intuition, mathematical formulas and genetic algorithms.

title Intelligence in buildings: the potential of advanced modelling
source Automation in Construction 6 (5-6) (1997) pp. 447-461
summary Intelligence in buildings usually implies facilities management via building automation systems (BAS). However, present-day commercial BAS adopt a rudimentary approach to data handling, control and fault detection, and there is much scope for improvement. This paper describes a model-based technique for raising the level of sophistication at which BAS currently operate. Using stochastic multivariable identification, models are derived which describe the behaviour of air temperature and relative humidity in a full-scale office zone equipped with a dedicated heating, ventilating and air-conditioning (HVAC) plant. The models are of good quality, giving prediction accuracies of ± 0.25°C in 19.2°C and of ± 0.6% rh in 53% rh when forecasting up to 15 minutes ahead. For forecasts up to 3 days ahead, accuracies are ± 0.65°C and ± 1.25% rh, respectively. The utility of the models for facilities management is investigated. The "temperature model" was employed within a predictive on/off control strategy for the office zone, and was shown to substantially improve temperature regulation and to reduce energy consumption in comparison with conventional on/off control. Comparison of prediction accuracies for two different situations, that is, the office with and without furniture plus carpet, showed that some level of furnishing is essential during the commissioning phase if model-based control of relative humidity is contemplated. The prospects are assessed for wide-scale replication of the model-based technique, and it is shown that deterministic simulation has potential to be used as a means of initialising a model structure and hence of selecting the sensors for a BAS for any building at the design stage. It is concluded that advanced model-based methods offer significant promise for improving BAS performance, and that proving trials in full-scale everyday situations are now needed prior to commercial development and installation.

title DEFLECT: A Computer Aided Learning Package for Teaching Structural Design - Phase Two
doi https://doi.org/10.52842/conf.ecaade.1997.x.f6j
source Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
summary This paper reports on Phase Two of a SHEFC funded project jointly carried out by the Department of Civil, Structural and Environmental Engineering, University of Paisley, the Mackintosh School of Architecture, and Lamp Software. The project aims to build a computer-assisted learning package on the response of structures to load. The software will be used as an interactive teaching tool for both architectural and engineering students.

The package has four levels: Beginners (Level 1), Intermediate (Level 2) and Advanced (Levels 3 and 4). The first two levels have been completed after continuous feedback from both institutions. Level 1 is geared towards architectural and engineering students to help them understand structural behaviour of building components, such as deflection. Level 2 is a graphical editor that enables students to draw precisely the structure of their designs, investigate the deflection of structural members and identify areas of tension and compression. Levels 3 and 4 are a design tool which is aimed at architectural and civil engineering students where they can design and analyse realistic structures by choosing structural members from a library, and specify materials and multiple loads.

Phase One of DEFLECT was presented in the 14th ECAADE conference , which was held at the University of Lund, Sweden. In Phase Two, the range of structural examples was expanded to include typological classics. This was accompanied by additional teaching and learning material. The package was enlarged to include bending moment and shear force diagrams, tapered and curved members, and additional materials such as glass.

title Geometric Modeling
source New York: Wiley Computer Publishing
summary A comprehensive, up-to-date presentation of all the indispensable core concepts of geometric modeling. Now completely updated to reflect the most recent developments in the field, Geometric Modeling clearly presents and compares all the important mathematical approaches to modeling curves, surfaces, and solids, and shows how to shape and assemble these elements into more complex models. Its thorough coverage also includes the concomitant geometric processing necessary, e.g., the computation of intersections, offsets, and fillets. Written in a style that is virtually free of the jargon of special applications, this unique book focuses on the essence of geometric modeling and treats it as a discipline in its own right. This integrated approach allows the reader to focus on the principles and logic of geometric modeling without requiring background knowledge of CAD/CAM, computer graphics, or computer programming. Supported by more than 300 illustrations, Geometric Modeling appeals to the reader's visual and intuitive skills in a way that makes understanding the more abstract concepts much easier. This new edition features a host of new application areas, including topology, special effects in cinematography, the design and control of type fonts, and virtual reality, as well as numerous application examples. For computer graphics specialists, application designers and developers, scientific programmers, and advanced students, Geometric Modeling, Second Edition will serve as a complete and invaluable guide to the entire field.

title Energy optimized-ventilation constrained variable air volume system control
source Automation in Construction 6 (5-6) (1997) pp. 463-470
summary The analytical energy performance of an advanced energy optimized-ventilation constrained control approach to variable air volume systems was compared to four other controls. The other controls are either currently used or have been proposed in the literature. The advanced control demonstrated its potential to meet the ventilation requirements of ASHRAE Standard 62-1989 for every zone of the building with minimal energy consumption. The analytical work was carried out in a single story prototypical commercial building. The building was analyzed in five US cities to provide insight into the impact of climate on the performance of the advanced control. The advanced control consumed less total energy, considerably less in some cities, than the other four controls. The advanced control provides an excellent opportunity to apply to buildings new automation equipment and software never attempted before.

source CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 475-480
summary Increasing complexity of today's buildings requires a high level of integration in the planning process. Common planning strategies, where individual project partners cooperate mainly to exchange results, are not suitable to jointly develop project goals and objectives. Integrated planning, a more holistic approach to deal with complex problems, is based on a high degree of communication among team members and leads to a goal oriented cooperation. This paper focuses on the application of an advanced groupware approach suitable to support efficiently an integrated design process in construction. First an appropriate planning process model will be presented, which differs from common product model approaches and takes into account the great importance of team- and goal orientation in integrated planning. Then the idea of an open CSCW platform is proposed, which basic structure and containing elements are based on the defined planning model. Appropriate cooperative planning scenarios can then be ad-hoc modeled and configured dynamically on this CSCW platform according to the requirements of the specific project. For the participants of the planning process, the resulting groupware approach represents an integrated computer based working environment. This environment allows a kind of immersion into the project. Finally a prototypical implementation of this approach will be shortly discussed.

title Dominant and recessive genes in evolutionary systems applied to spatial reasoning
source A. Sattar (Ed.), Advanced Topics in Artificial Intelligence: 10th Australian Joint Conference on Artificial Intelligence AI97 Proceedings, Springer, Heidelberg, pp. 127-136
summary Learning genetic representation has been shown to be a useful tool in evolutionary computation. It can reduce the time required to find solutions and it allows the search process to be biased towards more desirable solutions. Learn-ing genetic representation involves the bottom-up creation of evolved genes from either original (basic) genes or from other evolved genes and the introduction of those into the population. The evolved genes effectively protect combinations of genes that have been found useful from being disturbed by the genetic operations (cross-over, mutation). However, this protection can rapidly lead to situations where evolved genes in-terlock in such a way that few or no genetic operations are possible on some genotypes. To prevent the interlocking previous implementations only allow the creation of evolved genes from genes that are direct neighbours on the genotype and therefore form continuous blocks. In this paper it is shown that the notion of dominant and recessive genes can be used to remove this limitation. Using more than one gene at a single location makes it possible to construct genetic operations that can separate interlocking evolved genes. This allows the use of non-continuous evolved genes with only minimal violations of the protection of evolved genes from those operations. As an example, this paper shows how evolved genes with dominant and re-cessive genes can be used to learn features from a set of Mondrian paintings. The representation can then be used to create new designs that contain features of the examples. The Mondrian paintings can be coded as a tree, where every node represents a rectangle division, with values for direction, position, line-width and colour. The modified evolutionary operations allow the system to cre-ate non-continuous evolved genes, for example associate two divisions with thin lines, without specifying other values. Analysis of the behaviour of the system shows that about one in ten genes is a dominant/recessive gene pair. This shows that while dominant and recessive genes are important to allow the use of non-continuous evolved genes, they do not occur often enough to seriously violate the protection of evolved genes from genetic operations.

summary Current construction design methods are not able to produce all the information necessary for the construction process. Increased exploitation of building design information, especially dimensional control and identification, is necessary. The construction industry should take advantage of automation to increase productivity and quality. 'Product model thinking' is designed to solve these problems, but demands advanced devices and changes in traditional working methods. This paper describes some key aspects of product model thinking and its exploitation on the construction site in the near future.
