Abstract The study's goal is to categorize surface weathering types and define their characteristics for the design of building exteriors with weathering in mind. It then aims to validate these types and characteristics through architectural case analyses. Additionally, it challenges the conventional perspective that considers a building complete upon finishing construction by examining the alterations to building exteriors caused by weathering. This study is structured into two main parts: a theoretical exploration of weathering and an analysis of architectural case studies. In the theoretical investigation, weathering on building surfaces is categorized into three types: erosion, staining, and discoloration. These weathering types are associated with features like irregularity in exteriors, blending with neighboring buildings, and the representation of traces. The architectural case studies consist of three specific instances in two categories: parapets and staining on exterior walls, and discoloration of finishing materials. To assess the methods and outcomes of incorporating weathering on exteriors in each case, an analysis is conducted based on the architect's original intent, design approach, and the changes in the exterior. This analysis revealed that the alterations in building exteriors due to weathering can be turned into positive elements, depending on contextual factors such as the surrounding environment or building purpose. Furthermore, this study demonstrates that the perception of a building's completeness can change based on the architect's intentions or users' interpretations of weathering effects. The significance of this study lies in recognizing the potential of weathering on building surfaces to facilitate the design of sustainable exteriors requiring minimal maintenance.
