title	The Building Design Advisor

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, schematic design 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 any number of 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 supplies “smart” default values from a Prototypical Values Database (PVD) for all non-geometric parameters required as input to the analysis and visualization tools linked to the BDA. In addition to the SGE and the PVD, the initial version of the BDA is linked to a daylight analysis tool, an energy analysis tool, and a multimedia Case Studies Database (CSD). The next version of the BDA will be linked to additional tools, such as a photo-accurate rendering program and a cost analysis program. Future versions will address the whole building life-cycle and will be linked to construction, commissioning and building monitoring tools.

title	Occupational Performance Theory as a Support to Design of the Built Environment for Persons with Disabilities
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary	Architectural practice should not be considered only a method of building buildings, but also a process of creating places for those who will use them. The interdependent nature of humans and the environment has provided architects and designers with a challenge; to build not only a space, but also a place in which human performance occurs. Environment -- behavior relations are complex and transactional. An understanding of this relationship facilitates the creation of environments that improve the quality of life for the buildings users. A strong understanding of the complexities of the environment is greatly enhanced by knowledge of the performance of the person. Knowledge of the person as a unique being who assumes different roles, possesses skills, and has attributes (abilities) allows the designer a greater respect of the dynamic experience of a person engaged in activity within an environment. The theory of occupational performance supports the understanding of the person and the persons daily tasks. These models describe human performance components and human performance areas. They also acknowledge that the person is engaged in activity within an environment. These models could prove to be invaluable to designers and architects interested in using knowledge of the persons in conjunction with knowledge of the environment to create spaces for people with disabilities.

summary	Charlas Magistrales 2There never has been such an exciting moment in time in the extraordinary 30 year history of our subject area, as NOW,when the philosophical theoretical and practical issues of virtuality are taking centre stage.The PastThere have, of course, been other defining moments during these exciting 30 years:• the first algorithms for generating building layouts (circa 1965).• the first use of Computer graphics for building appraisal (circa 1966).• the first integrated package for building performance appraisal (circa 1972).• the first computer generated perspective drawings (circa 1973).• the first robust drafting systems (circa 1975).• the first dynamic energy models (circa 1982).• the first photorealistic colour imaging (circa 1986).• the first animations (circa 1988)• the first multimedia systems (circa 1995), and• the first convincing demonstrations of virtual reality (circa 1996).Whereas the CAAD community has been hugely inventive in the development of ICT applications to building design, it hasbeen woefully remiss in its attempts to evaluate the contribution of those developments to the quality of the built environmentor to the efficiency of the design process. In the absence of any real evidence, one can only conjecture regarding the realbenefits which fall, it is suggested, under the following headings:• Verisimilitude: The extraordinary quality of still and animated images of the formal qualities of the interiors and exteriorsof individual buildings and of whole neighborhoods must surely give great comfort to practitioners and their clients thatwhat is intended, formally, is what will be delivered, i.e. WYSIWYG - what you see is what you get.• Sustainability: The power of «first-principle» models of the dynamic energetic behaviour of buildings in response tochanging diurnal and seasonal conditions has the potential to save millions of dollars and dramatically to reduce thedamaging environmental pollution created by badly designed and managed buildings.• Productivity: CAD is now a multi-billion dollar business which offers design decision support systems which operate,effectively, across continents, time-zones, professions and companies.• Communication: Multi-media technology - cheap to deliver but high in value - is changing the way in which we canexplain and understand the past and, envisage and anticipate the future; virtual past and virtual future!MacromyopiaThe late John Lansdown offered the view, in his wonderfully prophetic way, that ...”the future will be just like the past, onlymore so...”So what can we expect the extraordinary trajectory of our subject area to be?To have any chance of being accurate we have to have an understanding of the phenomenon of macromyopia: thephenomenon exhibitted by society of greatly exaggerating the immediate short-term impact of new technologies (particularlythe information technologies) but, more importantly, seriously underestimating their sustained long-term impacts - socially,economically and intellectually . Examples of flawed predictions regarding the the future application of information technologiesinclude:• The British Government in 1880 declined to support the idea of a national telephonic system, backed by the argumentthat there were sufficient small boys in the countryside to run with messages.• Alexander Bell was modest enough to say that: «I am not boasting or exaggerating but I believe, one day, there will bea telephone in every American city».• Tom Watson, in 1943 said: «I think there is a world market for about 5 computers».• In 1977, Ken Olssop of Digital said: «There is no reason for any individuals to have a computer in their home».The FutureJust as the ascent of woman/man-kind can be attributed to her/his capacity to discover amplifiers of the modest humancapability, so we shall discover how best to exploit our most important amplifier - that of the intellect. The more we know themore we can figure; the more we can figure the more we understand; the more we understand the more we can appraise;the more we can appraise the more we can decide; the more we can decide the more we can act; the more we can act themore we can shape; and the more we can shape, the better the chance that we can leave for future generations a trulysustainable built environment which is fit-for-purpose, cost-beneficial, environmentally friendly and culturally significactCentral to this aspiration will be our understanding of the relationship between real and virtual worlds and how to moveeffortlessly between them. We need to be able to design, from within the virtual world, environments which may be real ormay remain virtual or, perhaps, be part real and part virtual.What is certain is that the next 30 years will be every bit as exciting and challenging as the first 30 years.

title	Methods of control for robotic brick masonry
source	Automation in Construction 4 (4) (1996) pp. 281-292
summary	The major use of brick masonry units in the U.S. is in facades for office buildings and single family homes. The traditional method for building masonry walls is on-site by bricklayers. An alternative method is panelization or prefabrication of brick panels in a plant environment. While many mechanical problems exist, the real-time control represents a challenging aspect of robotizing brick masonry work. This paper presents an effort to study the development of an experimental robotic masonry system and its relevant control modules. It also describes two control frameworks for different levels in a robotic brick masonry prototype: (a) local control, and (b) global control. The local control system includes three work cells: (a) gripping and handling, (b) quality control, and (c) brick placement. First, the components and equipment used in a work cell are listed, then the experimental work performed with them is discussed to show how sensors are used for dehacking, brick placement, brick color detection, and brick size measurements. The paper then continues to describe a global control system that will integrate the three local work cells utilizing a hierarchical structure.

title	Autonomous vehicle navigation with real-time 3D laser based positioning for construction
source	Automation in Construction 5 (4) (1996) pp. 261-272
summary	Autonomous Guided Vehicles (AGVs) are a way of life in manufacturing where navigation can be done in a structured environment. Construction is an unstructured environment and requires a different type of navigation system to deal with three dimensional control and rough terrain. This paper provides a review of navigation systems that utilize dead-reckoning in conjunction with absolute referencing systems such as beacon-based systems, and vision and mapping based system. The use of a real-time laser based technology is demonstrated as a new form of navigation. This, technology does not rely on dead reckoning. The paper outlines the issues and strategies in guiding an autonomous vehicle utilizing only the laser-based positioning system. Algorithms were developed to provide real-time control of the AGV. The laser based positioning system is unique in that it provides three dimensional position data with five updates per second. No other system can provide this level of performance. This allows for control of end effectors and autonomous vehicles in complex and unstructured three dimensional environments. The use of this new type of navigation makes possible the automation of large complex assemblies in rough terrain such as construction.

title	Improving life-cycle information management through documentation of project objectives and design rationale
source	University of California, Berkeley, Department of Civil Engineering
summary	Fragmentation is a defining characteristic of the US building industry that has evolved with increased specialization in building disciplines, and is exacerbated by the present industry business model. While the industry has agreed that productivity and product quality can be dramatically improved by information integration and communication, it has not agreed what information is most important to share to achieve these improvements. Traditional documentation in drawings and specifications captures only the final product of building design decisions. Yet, reported building failures indicate that a lack of understanding between project participants regarding their diverse objectives may be a key factor in failure. This deficiency leads to an inadequate understanding of the rationale behind the myriad design decisions that must work in concert to achieve a global set of project objectives. This information is routinely lost under current information management practices as the building moves through its life cycle. The dissertation develops an innovative information framework intended to effectively structure and manage building life-cycle information. The framework contains a product model that represents the details of a building design that are traditionally documented for sharing between project phases. Two additional elements are integrated with this product model to document key information that is currently lost. Explicit Global Objectives define the overall purpose of a building project by explicitly identifying its intended performance and the criteria for evaluating their achievement. Design Rationale Records capture the associations between individual details of the product model and the objectives that these details are meant to achieve. This information is linked within the framework so that it can be archived, reviewed, and updated in an integrated fashion as a building project moves through time. Example applications of the framework are given. Documenting this key information has benefit across the building life cycle. Participants can more clearly specify project objectives. Multi-criteria evaluation of alternative design solutions and construction methods can be better supported, and the resulting decisions better documented for sharing amongst participants. Comprehensive commissioning can be more cost-effectively performed. During operations, evaluation of the actual performance of a building and detection of maintenance problems can be enhanced.

title	The Present and Future, Development of CAD Exploration in the Office of City’s Architect
source	CAD Creativeness [Conference Proceedings / ISBN 83-905377-0-2] Bialystock (Poland), 25-27 April 1996 pp. 147-157
summary	The usage of computer as a standard tool for an architect became obvious in the past few years. Late 90's along with their rapid development of technology, followed by the growing amount of computer hardware on the market /constantly better and cheaper at the same time/ caused the big changes in the possibilities of project's presentation. The lack of necessary memory to perform proper calculations for high quality rendered images no longer exists. The question raised most commonly by all leading computer software producers concerns the amount of time in which those calculations can be carried out. The race continues while once again, the price of already existing hardware drops rapidly. All these facts make computer more accessible for a potential user such as an architect. Additionally CAD programmers try to make programs as friendly as possible, reducing constantly the amount of time required to learn the program, at least at its bases. As the result, in the next few years, computer may become a standard, at least in some ways of project's presentation. Once again we may face the problem, when the everyday life goes far beyond the expectations. The question appears, how can all kinds of architectural authorities be prepared for constant changes in this field.

title	Artificial Life
source	Boden, M. A. (1996). The Philosophy of Artificial Life, 39-94.New York and Oxford: Oxford University Press
summary	Artificial Life contains a selection of articles from the first three issues of the journal of the same name, chosen so as to give an overview of the field, its connections with other disciplines, and its philosophical foundations. It is aimed at those with a general background in the sciences: some of the articles assume a mathematical background, or basic biology and computer science. I found it an informative and thought-provoking survey of a field around whose edges I have skirted for years. Many of the articles take biology as their starting point. Charles Taylor and David Jefferson provide a brief overview of the uses of artificial life as a tool in biology. Others look at more specific topics: Kristian Lindgren and Mats G. Nordahl use the iterated Prisoner's Dilemma to model cooperation and community structure in artificial ecosystems; Peter Schuster writes about molecular evolution in simplified test tube systems and its spin-off, evolutionary biotechnology; Przemyslaw Prusinkiewicz presents some examples of visual modelling of morphogenesis, illustrated with colour photographs; and Michael G. Dyer surveys different kinds of cooperative animal behaviour and some of the problems synthesising neural networks which exhibit similar behaviours. Other articles highlight the connections of artificial life with artificial intelligence. A review article by Luc Steels covers the relationship between the two fields, while another by Pattie Maes covers work on adaptive autonomous agents. Thomas S. Ray takes a synthetic approach to artificial life, with the goal of instantiating life rather than simulating it; he manages an awkward compromise between respecting the "physics and chemistry" of the digital medium and transplanting features of biological life. Kunihiko Kaneko looks to the mathematics of chaos theory to help understand the origins of complexity in evolution. In "Beyond Digital Naturalism", Walter Fontana, Guenter Wagner and Leo Buss argue that the test of artificial life is to solve conceptual problems of biology and that "there exists a logical deep structure of which carbon chemistry-based life is a manifestation"; they use lambda calculus to try and build a theory of organisation.

title	On Linguistic Aspects from a Cross-cultural Perspective
source	International Conference on Generative Art
summary	The goal of this paper is to discuss the issue of culture and its relationship to language and cognition by dealing with a number of lexical concepts, grammatical concepts and cultural scripts. Taking a moderate view, I reconcile universalism and ethnocentrism and argue that the study of culture-specific aspects of language has both a theoretical and practical importance. The role of universal semantic primes is obvious in culture-specific words such as the Japanese amae (a peculiarly Japanese emotion) which, though unique and untranslatable, can be accurately and intelligibly defined in terms of semantic primes (Wierzbicka, 1996). The view that meanings cannot be fully transferred from one language to another is supported by the difference in meaning manifested in the different range of use of the word happy (a common, everyday word in modern English) and joyful (a more literally and stylistically marked term.). A cross-linguistic analysis of the concept ‘happy’in English, Romanian, German, French, Italian, points to the so-called ‘traditional Anglo-Saxon distate for extreme emotions’. As far as aspects of grammar connected with culture are concerned, I compare expressive grammatical devices like intensifiers in English, Romanian and Italian. The question the paper addresses is whether constructions like syntactic reduplication(e.g. bella bella) and the absolute superlative (e.g. bellissimo) are indeed linked with what has been called ‘the theatrical quality’ of Italian life (Barzini, 1964) or not. Relative to Romanian, I assume that the idea of intensity of a state or action is conveyed, in certain registers, by terms and expressions pertaining to basic element source domains such as fire (e.g. frumoasa foc ‘fire-beautiful’) and earth (e.g. frumusetea pamantului ‘beauty of the earth’) and also by syntactic reduplication (e.g. frumoasa-frumoaselor ’beauty of the beauties’). Finally, I approach aspects of pragmatics which are culturally determined in the sense that they express cultural norms, values, ideals, attitudes. For instance, preferences are expressed directly in English while in Japanese this manner is contrary to the ideal of enryo ’restraint, reserve’.

title	THE TRUE MODEL CONCEPT IN COMPUTER GENERATED SIMULATIONS
source	Full-Scale Modeling in the Age of Virtual Reality [6th EFA-Conference Proceedings]
summary	Each design product depends on a design model originated in the designer's mind. From initial design decisions even to the final product, each design step is a representation of this design model. Designers create and communicate using the design models in their minds. They solve design problems by recreating and transforming the design model and utilize various means to display the final form of the model. One of these means, the traditional paper-based media of design representation (drawings, mockup models) alienate the representation from the design model, largely due to the lack of the display of the 4th dimension. Architecture is essentially a four-dimensional issue, incorporating the life of the edifice and the dynamic perception of the space by people. However, computer generated simulations (walkthrough, flythrough, virtual reality applications) of architectural design give us the chance to represent the design model in 4D, which is not possible in the traditional media. Thus, they introduce a potential field of use and study in architectural design. Most of the studies done for the effective use of this potential of computer aid in architectural design assert that the way architects design without the computer is not "familiar" to the way architects are led to design with the computer. In other words, they complain that the architectural design software does not work in the same way as the architects think and design the models in their brains. Within the above framework, this study initially discusses architectural design as a modeling process and defines computer generated simulations (walkthrough, flythrough, virtual reality) as models. Based on this discussion, the "familiarity" of architectural design and computer aided design is displayed. And then, it is asserted that the issue of familiarity should be discussed not from the point of the modeling procedure, but from the "trueness" of the model displayed. Therefore, it is relevant to ask to what extent should the simulation simulate the design model. The simulation, actually, simulates not what is real, but what is unreal. In other words, the simulation tells lies in order to display the truth. Consequently, the study proposes measures as to how true a simulation model should be in order to represent the design model best.

title	EXPERIMENTAL SPATIAL STRUCTURES
source	Full-Scale Modeling in the Age of Virtual Reality [6th EFA-Conference Proceedings]
summary	To speak about Experimental Spatial Structures at first means to find the right definition. Therefore we have to find definitions for three different subjects experiment, space and structure. Experiment - that means to perform scientific experiments. The attempt, the test, the simulation, the model. To do experimental work, that means to take measurements, to count, to compare, to try analyzing, to find out differences between substances. In our case, the experimental character of our work is impressed on working by using different methods to show the basic idea of our theme. To act and to use the full-scale-models with your body. Space - that means architectural space which is defined through architectural spatial elements: wall, ceiling, floor, corner, staircase, way, opening, border, edge and so on. So to speak the substances we need to do our experiments. Structure - means order. The contemplation and the comparison of different spatial structures allows the division of different basic subjects like: euclidian structures or physical structures or the depth of space and so on. To analyze or to design architectural space by using spatial structures as one possibility to do architectural work. As a summary: the experiment or the attempt to show architectural, spatial structures. Space and spatial structures are not only impressed by forms but also and as a main thing by action and moving in space. The role of full-scale modeling, of experimental work related to “reality” in architecture is to simulate basic situations which are not dependent on ideas how they are developed in particular. We try to give some instructions or impressions of elementary architectural structures which can be used as instruments to design space of life.

title	Case-based conceptual design information server for concurrent engineering
source	Computer-Aided Design, Vol. 28 (5) (1996) pp. 361-369
summary	Conceptual design requires processing information from diverse sources in order to define the functional requirements, operating constraints, and evaluation criteria pertinent to accomplishing a prescribed goal.Historically, the design process focused on the functionality of an artifact for the end customer. Concurrent engineering broadens this focus to account for the concerns of `customers' not previously considered --those along the entire life cycle of an artifact, i.e. marketing, design, manufacture, distribution, operation and disposal. Expanding the design focus to include all of these customers places far greater informationaldemands on the designer. Case-based reasoning applies experience stored in a computerized form to solving similar problems in slightly altered contexts. It has been applied successfully to routine design whereboth the form and the content of design information can be encoded symbolically and manipulated using artificial intelligence techniques. Concurrent conceptual design presents unique problems for such anapproach because design information must be considered at many levels of abstraction and from many viewpoints.We describe an approach that provides the designer with case-based conceptual design information stored in the richly expressive medium of hypermedia (hypertext incorporating multimedia). Design cases ofindustry `best practices' in concurrent engineering are indexed to provide access through multiple interfaces, allowing the user to browse, explore, or pinpoint design case information. The Conceptual DesignInformation Server (CDIS) is implemented using emerging internet standards, such as those associated with the World Wide Web (WWW) and Wide Area Information Service (WAIS), coupled to a robustStructured Query Language (SQL) database and traditional cad packages.

title	Conceptual Collaborative Building Design Through Shared Graphics
source	IEEE Expert special issue on Al in Civil Engineering, June vol. 33-41
summary	The Interdisciplinary Communication Medium computer environment integrates a shared graphic modeling environment with network-based services to accommodate many perspectives in an architecture/engineering/construction team. Communication is critical for achieving better cooperation and coordination among professionals in a multidisciplinary building team. The complexity of large construction projects, the specialization of the project participants, and the different forms of synchronous and asynchronous collaborative work increase the need for intensive information sharing and exchange. Architecture/engineering/construction (A/E/C) professionals use computers to perform a specific discipline's tasks, but they still exchange design decisions and data using paper drawings and documents. Each project participant investigates and communicates alternative solutions through representational idioms that are private to that member's profession. Other project participants must then interpret, extract, and reenter the relevant information using the conventional idioms of their disciplines and in the format required by their tools. The resulting communication difficulties often affect the quality of the final building and the time required to achieve design consensus. This article describes a computer environment, the Interdisciplinary Communication Medium (ICM), that supports conceptual, collaborative building design. The objective is to help improve communication among professionals in a multidisciplinary team. Collaborative teamwork is an iterative process of reaching a shared understanding of the design and construction domains, the requirements, the building to be built, and the necessary commitments. The understanding emerges over time, as team members begin to grasp their own part of the project, and as they provide information that lets others progress. The fundamental concepts incorporated in ICM include A communication cycle for collaborative teamwork that comprises propose-interpret-critique-explain-change notifications. An open system-integration architecture. A shared graphic modeling environment for design exploration and communication. A Semantic Modeling Extension (SME), which introduces a structured way to capture design intent. A change-notification mechanism that documents notes on design changes linked to the graphic models, and routes change notifications. Thus, the process involves communication, negotiation, and team learning.

title	Awareness Space in Distributed Social Networks
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 615-628
summary	In the real work environment we are constantly aware of the presence and activity of others. We know when people are away from their desks, whether they are doing concentrated work, or whether they are available for interaction. We use this peripheral awareness of others to guide our interactions and social behaviour. However, when teams of workers are spatially separated we lose 'awareness' information and this severely inhibits interaction and information flow. The Theatre of Work (TOWER) aims to develop a virtual space to help create a sense of social awareness and presence to support distributed working. Presence, status and activity of other people are made visible in the theatre of work and allow one to build peripheral awareness of the current activity patterns of those who we do not share space with in reality. TOWER is developing a construction set to augment the workplace with synchronous as well as asynchronous awareness. Current, synchronous activity patterns and statuses are played out in a 3D virtual space through the use of symbolic acting. The environment itself however is automatically constructed on the basis of the organisation's information resources and is in effect an information space. Location of the symbolic actor in the environment can therefore represent the focus of that person's current activity. The environment itself evolves to reflect historic patterns of information use and exchange, and becomes an asynchronous representation of the past history of the organisation. A module that records specific episodes from the synchronous event cycle as a Docudrama forms an asynchronous information resource to give a history of team work and decision taking. The TOWER environment is displayed using a number of screen based and ambient display devices. Current status and activity events are supplied to the system using a range of sensors both in the real environment and in the information systems. The methodology has been established as a two-stage process. The 3D spatial environment will be automatically constructed or generated from some aspect of the pre-existing organisational structure or its information resources or usage patterns. The methodology must be extended to provide means for that structure to grow and evolve in the light of patterns of actual user behaviour in the TOWER space. We have developed a generative algorithm that uses a cell aggregation process to transcribe the information space into a 3d space. In stage 2 that space was analysed using space syntax methods (Hillier & Hanson, 1984; Hillier 1996) to allow the properties of permeability and intelligibility to be measured, and then these fed back into the generative algorithm. Finally, these same measures have been used to evaluate the spatialised behaviour that users of the TOWER space show, and will used to feed this back into the evolution of the space. The stage of transcription from information structure to 3d space through a generative algorithm is critical since it is this stage that allows neighbourhood relations to be created that are not present in the original information structure. It is these relations that could be expected to help increase social density.

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.

summary	This paper has reviewed the literature on the teaching of daylight systems design in architectural education, and found that traditionally such teaching has evolved around the prediction of the Daylight Factor (DF%), i.e. illuminance, via two methods one studio-based and another laboratory based. The former relies on graphical and/or mathematical techniques, e.g. the BRE Protractors, the BRE Tables, Waldram Diagrams, the Pepper-pot diagrams and the BRE formula. The latter tests scale models of buildings under artificial sky conditions (CIE sky). The paper lists the advantages and disadvantages of both methods in terms of compatibility with the design process, time required, accuracy, energy-consumption facts, and visual information. This paper outlines a proposal for an alternative method for teaching daylight and artificial lighting design for both architectural students and practitioners. It is based on photorealistic images as well as numbers, and employs the Lumen Micro 6.0 programme. This software package is a complete indoor lighting design and analysis programme which generates perspective renderings and animated walk-throughs of the space lighted naturally and artificially. The paper also presents the findings of an empirical case study to validate Lumen Micro 6.0 by comparing simulated output with field monitoring of horizontal and vertical illuminance and luminance inside the highly acclaimed GSA building in Glasgow. The monitoring station was masterminded by the author and uses the Megatron lighting sensors, Luscar dataloggers and the Easylog analysis software. In addition photographs of a selected design studio inside the GSA building were contrasted with computer generated perspective images of the same space.

title	Bi-directional Inference in Thermal Design
source	Design Computation: Collaboration, Reasoning, Pedagogy [ACADIA Conference Proceedings / ISBN 1-880250-05-5] Tucson (Arizona / USA) October 31 - November 2, 1996, pp. 133-143

summary	This paper demonstrates a computational bi-directional energy modeling approach for building design development. Conventional simulation tools may be labeled as mono-directional in that they require a more or Iess complete design definition in order to derive performance indicators. However, in certain circumstances, it may be desirable to reverse this process: a bi-directional (or "open") inference mechanism would allow for the identification of those changes in the design variables that would accommodate a desired change in a performance indicator. The performance-to-design mapping process is an ambiguous one: the same performance (e.g. energy use of a building, temperature variations in a space) may be achieved by different design configurations (various wall and window dimensions/properties, building orientation/massing, etc.). As a result, the actual implementation of a bi-directional inference tool is a rather difficult task. The development described in this paper utilizes a preference-based approach that involves the formalization of various external or internal constraints and preferences (such as code and standard requirements, results of post-occupancy studies, individual priorities of designers and their clients, etc.) in terms of normalized numeric scales. After a brief review of the underlying technology for the implementation of the inference engine, the paper demonstrates an actual design session using a bi-directional thermal simulation tool. Specifically, a use-scenario is described in which the designer explores the tradeoffs between various design variables (glazing area, glazing type, and floor mass) in view of the resulting energy performance of a typical residential building. The paper concludes with a discussion of the potential and limitations of the bi-directional approach toward active convergence support for performance-oriented design development.

title	Integrated Energy Modeling for Computational Building Design Assistance
source	Carnegie Mellon University, Department of Architecture
summary	Insights into the importance of energy modeling in building design have not yet resulted in the sufficient and systematic use of modeling tools in practice. In recent years, there has been considerable discussion on the limitations of simulation tools, and there is a noteworthy consensus as to the nature of the contributing factors (material and time implications, problematic user-interfaces, inefficient data communication structures, poor integration with CAD systems, absence of 'active' design support). This thesis deals with three research questions that are especially pertinent to the quest for active, multi-aspect design and simulation environments: (1) The appropriateness and feasibility of a methodologically consistent performance modeling approach through the entire design process. (2) Strategies for a structurally 'seamless' containment of performance simulation within a computational design environment. (3) Technologies to facilitate dynamic and interactive performance-to-design mapping. At a paradigmatic level, this thesis critically examines the existing responses to each of these questions, and proposes alternative computational frameworks and technologies to overcome some of the system-immanent ('endogenous') limitations of the existing approaches. At an operational level, this thesis demonstrates the proposed solutions by implementing an active thermal simulation module (NOD

summary	The natural and the man-made environment is under increasing stress. We are entering a phase when the exploitation of energy resources is likely to cause a dramatic acceleration in our rate of impact on the natural environment; in particular, there is cause for serious concern regarding the damaging visual impact of energy related developments - oil terminals, dams, power stations, electricity transmission lines, open cast mining - on remaining areas of relatively unspoilt rural landscape. In the developed countries, the urban environment is presenting architects, planners and development agencies with some of the most significant and intractable problems in the last decade of the 20 Century. The problems are the most chronic in those cities which rose to greatness at the height of the industrial revolution- as heavy industry has declined, industrial sites have become derelict, the working population has drifted away and housing has fallen below tolerable standards. Yet in most cases, much evidence of urban greatness remains - in the grandeur of the public buildings, in the scale of the cityscape and in the spirit of those who still have their homes, and their cultural roots, in the inner city.

summary	The quality of the built environment depends critically on the concept of sustainability and, in particular, on designs which are energy efficient and environmentally friendly. This paper gives an account of the successful application of computer-based simulations of the physical environment made available to architects through an Energy Design Advisory Service and used parametrically within a research project carried out jointly with a design and build company. It goes on to indicate how emerging multimedia technology can be used to provide an explanation, particularly to those who are technically unsophisticated, of the complexity of the way in which design decisions impact upon the energy efficiency and environmental friendliness of buildings.
