The Effect of Simultaneous and Sequential Performance Evaluations on Restricting the Formal Diversity of Design
Performance-based architectural design is an approach to consider building
performance as a key element in its generation and formation. This trend has
become possible due to the development of digital technologies which enabled
the designer to simulate the building performance digitally in different areas of
design such as constructional, environmental, etc. In this approach, the
performance assessment is an essential facility in the derivation of architectural
form. Previous studies showed different opinions about where, when and how to
apply evaluation criteria. Consequently, the research problem has been identified
as: there is no clear understanding of the effect of different methods of assessing
performance criteria (simultaneous and sequential) on the formal diversity of
design alternatives. Accordingly, the paper adopts a computerized design
strategy based on specific performance criteria and using commercial CAD
software to explore the impact of changing the sequence of performance criteria
on the formal diversity of design alternatives. The results show that the best
designs resulting from the simultaneous evaluation differ from those resulting
from the sequential evaluation. In addition, designs resulting from the sequential
evaluation process vary when the sequence of performance criteria adopted in
the evaluation is changed.
