Jr Thermal Comfort Analysis of Design Element in El’s Coffee Roastery Building Bandar Lampung: A Case Study of the Use of Glass Facades in a Tropical Climate

Abstract

Indonesia's tropical climate, characterized by high humidity, hot temperatures,
and intense solar radiation year-round, demands a more adaptive and thoughtful
architectural design approach. In this context, building designers need to
consider the balance between aesthetics and thermal comfort for space users. The
use of glass, for example, can provide abundant natural lighting and enhance a
building's visual character, but it can also increase the heat load of interior
spaces if not equipped with appropriate mitigation strategies. Therefore,
implementing effective air circulation, such as air conditioning devices, shading
devices, and reflective protective coatings, is crucial to reducing excess heat.
Facade design that is responsive to tropical climates is key to achieving optimal
building performance. This study examines the thermal comfort analysis and
application of architectural design elements to the El's Coffee Roastery building
in Bandar Lampung, with a particular focus on the function and quality of the
glass facade as a key element influencing the building's appearance and
performance in a tropical climate.
