During the Fall semester of 1993, while I was a non-registered student at U.C. Berkeley, I attended the course Introduction to Computing in Architecture held by Professor Yehuda Kalay together with Steven Murray, and several teaching assistants. The lessons of the course approached both theoretical and practical aspects of computer-aided architectural design. Professor Murray used to lecture mainly on the practical aspects of computer technology and computer drafting (being present also at lab sessions), while Professor Kalay would focus more on the theoretical aspects of architectural design in general, and CAAD in particular. Needless to say, in their haste to actually practise software packages such as Autocad, 3Dstudio and others, students were much more eager to participate during the lessons given by Steven Murray than during the abstract lessons on design theory and its possible interaction with a computing machine, given by Professor Kalay.
This happened more than ten years ago. Professor Kalay and Professor Murray each teach their own course today, and students come to college to learn architectural design, most probably with a greater personal acquaintance with computer technology, due to the daily use of Internet since childhood.
The MIT Press has just released Architecture's New Media, the massive book in which Yehuda Kalay publishes the results of his life-long research. Reading it gave me the chance to value what I was not ready to be taught then. In this book, the author addresses the question of computing in architecture from the standpoint of a designer and not from the standpoint of a draftsman. Therefore it is much more than a textbook for students: it is an overall reflection on architecture as a discipline and is more likely to be fully appreciated by scholars and professionals who have already experienced for some time the complexity of design and building process.
The fundamental question which the book tries to answer is: in what way may computers serve, and possibly improve, the process of architectural design nowadays? "Architecture," says Kalay, "as a practical form of art, has been in need of computation - and computational aids - since ancient times" (page?). So how may modern computers (strictly mathematical devices) generate solutions to design problems, or at least help the designer evaluate his own project, both during the ideation and the execution phases? Can computers offer more than the powerful instant 3D visualization of project ideas to which any designer is by now accustomed? No answer can be given to such a question without defining first what design is, how does it reach its final form, how and to whom it has to be communicated, how and by whom it has to be evaluated, etc. Thus the book is divided into five main parts: introduction, communication, synthesis, evaluation, future. Though arranged in a logical sequence, each part may be read quite independently from the others. The bibliography at the end of every chapter, related to the area under discussion, eventually helps the reader to study more deeply a very specific subject. (Unfortunately a similar organization was not applied to endnotes which all are gathered at the end of the book.)
In the Introduction Kalay gives the reader an overview of the nature and history of computing in general and computing in architectural design in particular, from the first generation of CAD systems to the actual situation. He also presents some knowledge-based design systems, like WorldView, developed by himself at the University of Buffalo, KAAD, developed at the University of Roma -La Sapienza, or ICADS developed at California Polytechnic and State University in San Luis Obispo, which are attempts at transforming computers from drafting tools into design assistants able to detect inadequacies according to embedded precise design rules. These programs will be further examined in the subsequent parts of the book.
The second part entitled "Communication" is structured
as an independent essay on the complex and reciprocal relationships
between visualization and communication. Though mostly interesting,
the subject goes far beyond architectural representation and
information management. The chapters on computer graphics which
present the basic systems of CAD (computer aided drafting) are
likely to become out of date rather soon, given the constant
and fast-paced evolution and increase of this kind of software
application, which make possible not only 3D but also 4D visualization.
Evaluation seems to be the answer to interactive communication between the architect and the computer during the successive steps of the design process. Kalay lists various types of evaluating methodologies, leading to the definition of algorithms that make it possible to quantify and verify some thematic aspects of the constructions planned: stability, thermal and acoustic characteristics, costs and so forth... The difficulty of these procedures rely in the accuracy of the possible prediction that can be made of the performances of non-existing buildings, according to specific goals that often have to be adjusted to ensure compatibility with other objectives.
But what about evaluating non-quantifiable qualities such as design aesthetics? Aesthetics is among the characteristics that can hardly be computed since its evaluation is essentially subjective. Yet the search for some scientific evaluation system that would help predict the future aesthetic result of design is precisely and paradoxically the very point that links and fuses the modern research to the former efforts of ancient and Renaissance architects. The problem of defining some mathematical laws that will guarantee the quality of a project idea is neither recent nor modern. There is only a modern approach to solve such a query, which is to require assistance from the blooming computer technology. But while the "Ancients" seem to have reached some self-satisfactory conclusions that were published in numerous treatises, we -- Moderns -- are still searching.
Forecasting the future is rather risky, Kalay says. Nevertheless some trends toward specific evolutions are already noticeable. They all reveal enhancement of shared information and collaborative design. Evaluation of quantifiable qualities will become more and more sophisticated and efficient thanks to Agencies of Intelligent Design Assistants (IDeAs): cooperative decision-making systems.Architecture's New Media is a book that is surely worth reading. By providing the reader with an important amount of objective information, it leads him/her into a deep reflection on the recent evolution of the architect's work and role, opposed to its traditional essence. The totally un-passionate tone of the writer will raise passion in the reader, especially when asking some simple question such as:
