Comparative Analysis Study of Building Envelopes between Vernacular and Modern Houses in Coastal Areas of Java against the Wet Tropical Climate in Indonesia

Abstract

Indonesia is an archipelagic country that has a wet tropical climate. This climate has hot weather throughout the year yet accompanied by high rainfall in certain months of the year. With the climate situation mentioned previously, the choice of material for residential building envelope is crucial for residential architects. Traditional architecture on the island of Java is architecture in which the covering material of a building is made of woven bamboo sheets or wooden sheets parallelly arranged with wooden sticks as the main construction material. Unfortunately, buildings with these materials have been abandoned and replaced with brick structures introduced by colonial influences that colonized Indonesia. Wood and bamboo materials are known as materials that have low thermal lag so that heat transfer can occur rapidly without any delay, hence why they are considered suitable for coastal areas. In this research, the team will prove the advantages and disadvantages of envelope materials based on literature studies on energy efficiency theory and the selection of building envelope materials. From the results of the research carried out, it is a material framework for further research, namely how to use building envelope materials in accordance with their function.
