Parametric Louver Design System Based On Direct Solar Radiation Control Performance

Abstract

The purpose of this study is to develop a parametric design methodology that combines parametric design with thermal analysis. This new approach suggests that a form emerges from a performance based analysis. The result of the study is a parametric louver design system, which optimizes a louver form based on its direct solar radiation control performance. The system is composed of three parts: the analysis part, parametric design part, and optimization part. Each part functions interactively to produce an output. The output is the best performing louver form for the given site from the aspect of its yearly direct solar radiation control performance. The study applies the suggested design system to a case study, which is a virtual curtain wall office building in Seoul, Korea. The system produces the best performing louver form for each of the building′s two main facades. The study compares the thermal performance of the best performing louver design with a commonly used louver design using a different software, Ecotect Analysis 2011. The Ecotect′s thermal analysis confirms that the suggested louver forms perform better, reducing the building′s heating and cooling loads.
