Abstract
The design as a process is not a new topic in architecture, yet some theories are widely unexplored, such as the multi-stage decision-making (MD) process. This design method provides multiple solutions for one design problem and is characterized by design stages. By adding new building components in every stage, multiple solutions are created for each design solution from the previous stage. If the MD process is to be applied in architectural practice, fundamental and theoretical knowledge about it becomes necessary. This paper investigates the impact of sequence of design stages on the design solutions in the MD process. A basic case study provides the necessary data for comparing different sequences and gaining fundamental knowledge of the MD process. The study contains a parametric model for building generation, a parametric Life Cycle Assessment tool and an optimization mechanism based on Evolutionary Algorithms.

Notes
- 1.
For this case study, the model has been visually programmed using the software Grasshopper for Rhinoceros3D.
- 2.
Galapagos which is a component included in Grasshopper, was used for conducting all optimizations within the case study.
- 3.
Another important information to keep in mind when evaluating design solutions is that slight deviations in the results are common for optimization processes which operate based on EA. These deviations are to be considered before making conclusions about the different sequences.
