Abstract
A glass facade is commonly used by modern building nowadays, even in the tropical area with its characteristic. Thus, buildings often face a problem with thermal comfort. Passive design strategy supposed to be considered by the architect in order to avoid inconvenience with the heat. This strategy utilized the architectural element as the tools to reach the comfort level. The aim of this study was to optimize the thermal behavior of the building itself by the modification of solar shading types and materials. EnergyPlus was used as a simulation tool in this study. The results show that solar gain exterior window can be reduced by 52,73% by using concrete louvre and wood louvre.

Dapat dilihat bahwa untuk daerah tropis seperti Indonesia, penggunaan alumunium sebagai material solar shading pada bangunan tidak disarankan
Summary
Material yang digunakan sebagai komponen peneduh eksterior juga akan memberikan pengaruh terhadap kinerja thermal pada bangunan (Lechner, 2007). Solar shading merupakan elemen utama yang harus dipertimbangkan untuk meningkatkan target efisiensi energi pada bangunan (ES-SO, 2018). Tahapan survey literature dilakukan utnuk menentukan parameter solar shading, baik bentuk, ukuran maupun material dan thermal propertiesnya. Berdasarkan kemampuan program simulasi, maka jenis louvre dan fixed dipilih untuk digunakan pada penelitian ini.
