An investigation of the performance of split air conditioning (AC) unit in some apartments around Jabodetabek is reported. The type of split AC unit and interior design of the apartments is uniquely developed to examine their effect to the cooling coefficient of performance (COPc). The investigation was focused on the establishment of the flow pattern uniqueness depend of the air conditioning unit types. Using computational fluid dynamics tool, several variables were exploited such as type of split AC, apartment location, air temperature and velocity. It is obtained specific air flow pattern from each room within operated split AC unit which is determine the COPc rates.Based on the 25 simulation, cassette AC types succeed in almost 5 apartment unit only at Kemang View, Bekasi it is only at the second fail with the floor suspended type. They succeed to decrease the room temperature spread inside the apartment room unit. Airflow pattern of cassette is the best amongst them. The second position is the wall types; they win in Season City, Icon Condotel and Paragon Square only fail in East Casablanca and Kemang View. The lowest COPc is the floor standard types; they unsucceed in Season City, Icon Condotel and Paragon Square. Practical applications:The effort to reduce the electricity energy consumption of air conditioning operation in the building industry is in line to the Indonesia government policy. The selection of air conditioning unit which is the best COPc is the one method to achieve the energy saving program. Moreover the number of apartment construction in Indonesia is very excessive especially in the big cities such as in Jabodetabek (Jakarta, Bogor, Depok, Tangerang and Bekasi) area.
