Facade Design Optimization Process for Adaptive Reuse Projects using Daylight Performance Simulation

Purpose: Design methodologies have changed as technologies evolving in the architectural design field. It is possible to identify and apply performance criteria in the pre-construction stage of a building through simulation in fields such as daylight, thermal environment, structure, etc. Sustainable development, considering the comfortable indoor environment and eco-friendly aspects for the occupant, and through this, it will be possible to propose various types of passive design. Method: In this study, parametric design was implemented using Rhino and Grasshopper, and daylight environment analysis was conducted using ClimateStudio, an building performance simulation program. Furthermore, through a comparative analysis of prior research, the types of exterior shading devices for buildings were classified, and their design characteristics were systematically analyzed. Based on this, a simulation was performed using the implemented shading device and the results are compared and analyzed. Result: As a result of the simulation, high-performance shading devices were selected from the louver type or panel type according to design type, and the differences and characteristics of each type were compared and analyzed. Additionally, the values from each shading device were compared with values according to LEED standards. This comparison was visualized through ClimateStudio to achieve intuitive results, and LEED credit evaluation was also possible concurrently. When this optimization design process is applied to the actual design stage, it will be possible to propose a high-performing passive shading device design according to the use and conditions of each building.
