| Abstract |
Perforated metal sheets are used as panels of facades for controlling environmental factors while ensuring user’s visibility. Despite their
functional potentials, only a specific direction of facades or an orientation of a building was considered in the relevant studies. This study
proposed a design methodology for the perforated panel facades that reflects the location on the facades and the user’s requirements. The
optimization of quantitative and qualitative performance is achieved through communication between designers and users in a VR system. In
optimizing quantitative performances, designers use machine learning techniques such as clustering and genetic algorithm to allocate optimal
panels on the facades. In optimizing qualitative performances, through the VR system, users intervene in evaluating performances whose
preferences are depending on them. The experiment using the office project showed that designers were able to make decisions based on
clustering using GMM to optimize multiple quantitative performances. The gap between the target and final performance could be narrowed
by limiting the types of perforated panels considering mass customization. In assessing visibility as a qualitative performance, users were able
to participate in the design process using the VR system. |
