Since ancient times humans have been striving to find ways in order to adapt to this world’s climate. Start with a simple open fire to the modern electrical or even green powered heating system. However even to this day there are some areas in different parts of the world that still relies on open fire for indoor heating. Which, if maintained for a long time will cause severe respiratory problems that can lead to death.
According to United Nations’ Statistics, the usage of combustible fuels for household energy results in Indoor air pollution that caused 4.3 million deaths in 2012 of which 60%of the cases are women and girls.
Even though 13% of the global population still lacks electricity, solving this problem is not as simple as changing the power source. In most of the open fire usage, the fire is not only used for heating but also plays a role in the local tradition.
In this study Dani Tribe from Indonesia have been chosen as a study case. Even Though located in tropical areas, the high-altitude location creates a warm and humid climate in the day and relatively cold (Up to 14-degree Celsius) temperature at night. In such climates Dani people rely on open fire as indoor heating source at night and also use the smoke to repel mosquitoes and preserve the Roof Structure. However, this Practice has led to 5.99% of the women population suffering from acute Respiratory Infection and in severe cases, also death (Tebay, 2020).
By understanding the local customs and values through literature study and simulating the indoor open fire inside Honai with Fire Dynamic System simulation, this study aims to provide a basic understanding about how to implement indoor open fire in vernacular houses FDS.
The goal is to provide a basic understanding of the current situation of temperature and smoke movement of indoor fire usage in Honai house according to social habits of local people. This understanding will lead to a better comprehension for future proposals of a better solution to lighten the smoke problem indoor fire user community.
