Abstract (engl.)
The design process can only be supported by the
computer, if the creative act of designing finds
consideration. Computer based design Systems (CAAD-
Systems) using object-orientated semantic building models
could contribute, but are not used in the design process
nowadays.
To design with today's CAAD systems, users need increased
“head“- work instead of using the system intuitivly, getting
supported in their creative decision making process. A
good CAAD system offers more information and invokes
creative imagination for each stage of the design process.
It motivates the designer, permits emotions, and provokes
its creative abilities. Genuine aid from the computer
begins, where the CAAD system makes things visible, of
which the less expierienced user is unaware of at first. This
paper wants to bring on the one hand, interdisciplinary
understanding of architecture and the architectural design
process and on the other hand the known methods from
computer science and the borders of today's computers
into agreement. The main objective is to point out whether
the use of building model data in CAAD systems can
support the architectural design process in its early stage.
Therefore, barriers to not using CAAD systems in the
phases of design are detected and answers are given to
how model-based CAAD systems can become attractive for
the use in different design phases, both from a qualitative
as from a quantitative point of view. Thereby the two
characteristics, the conscious and unconscious thinking
processes of creativity are addressed. Whom without,
“new“ design can’t be developed. The author comes to the
conclusion that improving interaction with the CAADsystem
is crucial, in order for them to be used in the design
process. Product-model-based objects could be used, as
construction unit objects are used in building models. Only
if the human user interface can be handled truely
intuitively, will building models be accepted by designers in
the early phases of design. Therefore semantic building
models are a condition for any necessary “intelligence“ of
an integrated design environment supporting CAAD
system.
