All three studios tested notions of representation, simulation and
the design process in relation to a post-industrial world and its
impact on how we design for it. The sites for two of these studios
were in the city of Berlin, where the spearhead of the information
age and a leftover of the industrial revolution overlap in an urban
condition that is representative of our world after the cold war.
The three studios describe a progressive shift in the use of
information technology in the design process, from nearly pure
image-driven simulation to a more low-tech, highly creative uses
of everyday computing tools. Combined, all three cases describe
an array of scenarios for content-supportive uses of digital
media in a design studio. The first studio described here, from USC, utilized computer
modeling and visualization to design a building for a site located within the former no-mans'
land of the Berlin Wall. The second studio, from SCI-Arc, produced an urban design proposal
for an area along the former Berlin Wall and included a pan-geographic design collaboration
via Internet between SCI-Arc/Los Angeles and SCI-Arc/Switzerland. The third and last studio
from Woodbury University participated in the 1997 ACSA/Dupont Laminated Glass
Competition designing a consulate general for Germany and one for Hong Kong. They
employed a hybrid digital/non-digital process extracting experiential representations from
simple chipboard study models and then using that information to explore an "enhanced
model" through digital imaging processes.
The end of the cold war was coincidental with the explosive popularization of information
technology as a consumer product and is poised to have huge impact on how and what we
design for our cities. Few places in world express this potential as does the city of Berlin.
These three undergraduate design studios employed consumer-grade technology in an
attempt to make a difference in how we design, incorporating discussions of historical
change, ideological premise and what it means to be an architect in a world where image and
content can become easily disconnected from one another.
Such a problem, in standard form, presents an objective function Z=f(x), of n variables x, to be
minimized and a system of linear equations and/or inequalities, on the same variables, which represent
the constraints and which define an admissible area for the solution.
The architectural organism is modelled as an assembly of parallelepiped shaped space entities or units,
provided with a certain number of "holes" that permit functional corresponding connection. The pursued
intent being optimal assembly.
The model, in its mathematical form, fits a standard Non-Linear M.P. (N.L.P.) problem, since the
objective function Z is non-linear and the constraints are represented by inequalities. In its graphic form it
reproduces an image of all the space units constituting the organism; moreover it is able to represent
these units, in their logical and physical individuality, and their mutual relationship, as well as the ones
with the external environment.
a) to analyse the economic, social, cultural and political factors which relate to the proposed
site for a new Media Centre in a deprived area of Glasgow.;
b) to model the physical characteristics of the site and its vicinity;
c) to explain to, and encourage participation of the community in the evaluation of design
ideas for the Media Centre and thereby create a "media culture"
But a very rigorous design is not always enough to start restoration work.
The real state that presents a historical building could have been modified
substantially from its original state due to previous interventions, wars,
seismic movements, erosion, biological aggressions or any other
So, it is necessary to join CAAD tasks with a simulation of the historical
process suffered by the building. Historical data and ancient cartography
must be the basis of all the CAAD works, and the quality of the computer
3D model can be established comparing it with the original available
This paper explains the CAAD works and the intervention proposals for
the restoration of the City Walls of Hondarribia, a small Spanish village
placed in the frontier between Spain and France. These Renaissance
bastioned walls were partially destroyed throughout many wars with
France. The exact knowledge of their original trace and dimensions only is
possible comparing the real CAD models with the plans that exist in the
Spanish Military Archives since the XVIth. century.
The digital store and index of all the historical information, their
comparison with real photographs of the city walls, the creation of photo
realistic images with the intervention proposals, and the influence of the
structural repairs in the final project will be explained in the CAAD context.
