This study raises the question of what the emotional significance of the digital patterns has and attempts to provide an answer to such a question. The purpose of this study is to propose a direction to effectively support the façade designs of buildings by understanding the emotive design characteristics of the patterns. This study explains the design patterns on façade designs. There are five types of digital patterns which include applied patterns, perforated patterns, layered patterns, cast patterns, and tiled patterns. Among those patterns, perforated patterns are focused in further detail. This study deals with identifying emotional effects of perforated design patterns. The emotional word 'asymmetrical' and 'irregular' shows the high average of the emotional value. In the bipolar adjectives, the high emotional value is 'irregular-regular' and 'asymmetrical-symmetrical'. Therefore, the final design characteristics of the perforated patterns are 'regularity' and 'symmetry'. This means to be able to use the perforated patterns in order to be perceived a building façade design as the regular and symmetrical emotional effect. In this paper, it is worth analyzing design characteristics of a building façade by the support of the digital technologies and discussing the utilization of design characteristics derived. This study has contributed to the process and method of deriving the analysis results.
