Assessing cooling energy of insulated building built in tropical country

Global warming is a huge issue and has become a global concern lately. The global warming issue is gaining more attention on reducing fossil energy since fossil energy has significantly exacerbated global warming. Since housing sectors are consuming significant fossil fuel energy, reducing housing energy consumption is necessary. One option discussed in this paper is to reduce the load on the air conditioner (AC) by applying insulation to the building. Reducing the AC energy will reduce the total energy consumption in the buildings. Building practice in a mild climate has shown that good insulation can reduce heating or cooling energy in the building. But using insulation in housing is not a common practice in Indonesia’s construction sectors. Simulating the use of insulation in housing will show how much energy reduction will be obtained, especially for air conditioning energy. The analysis in this study found that thermal comfort is related to air temperature and relative humidity in the room. This article will study the reliability of using insulation in buildings to reduce energy consumption and provide thermal comfort for the occupant.
