Thermal condition of Semarang heritage Tawang railways station

Abstract

Semarang City has a wet tropical climate. The wet tropical climate relatively has high solar radiation, high humidity, high daily air temperature, and low air movement. Moreover, heritage buildings are usually those that have adapted to the climate and environment around the building, especially for interior comfort. The purpose of the present study is to examine the interior heat conditions in heritage buildings that are still maintained by the design. The case study in this study is the interior of Tawang Station, Semarang, which has several functions, such as offices, shops and waiting rooms, which still use natural ventilation. The method was a measurement of objects, model simulation, and analysis. Measurement data were used to develop simulations using computing, namely Ecotect. The results of the analysis revealed the amount of heat produced by the interior design of Tawang Station. The interior design of Tawang Station is included as hot as indicated by the temperature, which is less than 30°C. Currently, Tawang Station still has a moderate value of thermal conditions, especially since the design entails lots of ventilation and high ceilings hence it has relatively high air movements.
