파라메트릭 디자인 툴을 이용한 루버 디자인과 파라미터 고찰

Purpose: Current digital technology creates an environment in which architects can design buildings in a single design tool and simulate daylight condition without transforming data. To date, however, research on louver design through daylight simulation and analysis of data is found to be insufficient, considering the design intent of the building from an architect’s or designer’ perspective. The purpose of this study is to recognize the problem of interior space due to excessive daylight, to examine the progress of the design through the analysis of the simulations carried out to solve these problems, and to consider what the architect should consider in the simulation process. Method: Atrium space at the top of the tower where problems are expected to be caused by excessive daylight has been chosen as the simulation location for this study. For the progress of study, the methods of analyzing data, along with the concept of daylight simulation models, Constant Daylight Autonomy (cDA) and the Useful Daylight Illuminance (UDI), are understood through examples. Parametric models are built through Rhino and Grasshopper, and daylight simulations are carried out through Ladybug and Honeybee, the plug-in of Grasshopper, and the results are analyzed. Result: This study is meaningful in terms of a process to automatically execute and store results for different alternatives generated by parameters set up in conjunction with parametric tools in the initial design process. In addition, this study will provide useful information to architects or students who want to design the daylight to fit the architect's design intent, as well as understanding the overall trend and evolutionary digital tools, as well as providing useful information about the lighting simulation process, how data is interpreted, and what needs to be considered in the simulation.
