Study between Comfortability, Materials, and Room’s Layout of The Library in The Bosscha Observatory Area

Bosscha Observatory is the oldest observatory in Indonesia, and it has a lot of history since its initial construction. The Bosscha Observatory has been included in the criteria for cultural heritage buildings since 2018. One of the supporting spaces for observatory activities is a library and reading room, which researchers use to collect literacy for interpretation of observation and research results. The reading room is important for researchers and visitors to obtain information about astronomy. Meanwhile, the library in this area is one of the Dutch heritage libraries with Dutch and English references as the main references for astronomy researchers. This research aims to reveal how the materials and layout of a space can influence the comfort of users of that space. This research uses a qualitative descriptive method, beginning with observation, literature study, and redrawing 2D and 3D visualizations from data obtained in the field. The results of this research will benefit readers regarding the existence of Dutch heritage buildings that need to be preserved by being reused without intervention from other artificial comfort factors.
