Abstract

Indonesia has no reliable thermal comfort standard that is based on research works. The current national standard (SNI 6390:2011) states only a single range of comfort temperature that is 25.5 °C Ta, with a range of +1.5 °C Ta. Previous thermal studies in a number of different buildings in Indonesia showed that the neutral (comfort) temperatures of subjects were about 27 to 28 °C, which is higher than the values stated in the standard. As a big country with various ambient temperatures, Indonesian needs a better and more reliable thermal comfort predictor which can be applied properly across the country. This study is an attempt to propose an initial Indonesian thermal predictor, in the form of a simple equation, which could predict comfort temperatures properly across the country. Reanalysing the previous comfort studies in Indonesia, a simple regression equation is constructed as to be used as the initial Indonesian comfort predictor. Using this predictor, the comfort temperatures in a lowland or coastal cities like Jakarta is found to be higher than the current comfort standard. It is expected that this predictor would help to provide a better indoor thermal environment and at the same reduce the cooling energy in air conditioning (AC) building, thus reducing a building’s carbon emissions.
