Abstract

The purpose of this research is to evaluate the effect of insulation on the reduction of air conditioning energy used in the condominium room. The base case models were built in the eQuest 3.65 energy simulation program, which will calculate the baseline energy consumption using the Bangkok meteorological data. Residential room plan in this study was adopted from previous research, which had surveyed data on room types in condominiums in Bangkok. This research created a simulated model of a 33 m2 room located at different positions in the condominium. The total of 6 positions included the room on the left, right and center of the building that located on the top floor and the middle floor. These rooms were different in the area of interior wall, exterior wall and roof. The 75- and 150-mm thick insulation were added to the existing wall and ceiling to evaluate the reduction of air conditioning energy. The results showed that insulation reduced cooling energy by 1.9-21.3% compared to the base case. Installation of a 75-mm thick insulation on the existing ceiling of the room on top floor showed the shortest payback period of 4.4-5.5 years. For rooms on the middle floor, installation of 75- mm thick insulation on the wall of the room on the right of the building facing to north and west was also showed the simple payback period within 5 years.
