THE ANALYSIS OF HOUSEHOLD ENERGY CONSUMPTION OF PUBLIC APARTMENTS IN INDONESIA: A CASE STUDY OF RUSUNAWA BUILDINGS IN BANDUNG CITY

This paper discussed what profiles of household energy consumption in the public apartments (namely Rusunawa) in Bandung, Indonesia. Data of household energy consumption were obtained through a survey conducted within the city in 2016. The energy consumption profiles of households and the household appliances were obtained through face-to-face interviews and measurements of appliances’ capacity using watt checker. Then, a calculation of the annual energy consumption, including gas and electricity, was conducted. The experimental results replied that the annual average operational energy for public apartments is 9.80 GJ/year, and the largest energy for the annual average energy is found for cooking (4.70 GJ/year) of operational energy followed by refrigerator (2.6 GJ/year), lighting (1.0 GJ/year), entertainment (0.9 GJ/year), cooling (0.3 GJ/year), power (0.2 GJ/year) and hot water (0.1 GJ/year). Most of the energy source of cooking came from LPG. Further, the operational energy usage patterns varied among households. The factor significantly contributing to the increase of the Rusunawa operational energy is the energy consumption for cooking and fridge. The profiles of CO2 emissions are identical to those of energy. Then, the potential energy-saving strategies for public apartments in Indonesia are proposed. The results of this analysis would be useful for further insights for policy making in Indonesia, specifically for the energy policy for achieving lowenergy as well as low-carbon societies
