Renovation through the Application of Parametric Design-Focused on the Exterior Renovation of Commercial Buildings in Urban Areas-

The purpose of this study is to discover the potential of parametric design as an alternative design method to overcome renovation limitations of commercial buildings in urban areas that are becoming increasingly important and complex. Four domestic renovation projects using parametric designs were selected and the methods and effects of it in response to commercial renovations were analyzed. The analysis results revealed that the characteristics of the parametric design method were effectively utilized in the renovation process of commercial buildings. Parametric design achieves the symbolism and representation required by the facade of commercial architecture appropriately and economically by precisely controlling the geometry while factoring construction through algorithms. In addition, by expanding the scope of renovation to the surrounding context and considering it in the design, the effect of renovation can be enhanced and a positive impact can be brought about in the public aspect of an urban environment.
