【 摘 要 】

The Hotel BC is using power source from PLN with capacity of 4300 kVA which is divided into 3 units of 2000 kVA transformer. Transformers are used to supply the load of Mall tenants, and Utility loads, such as Chiller, pumps and others. Problems found in the field are complaints from the hotel regarding the safety of electrical installations and wasteful, inefficient electrical costs. The purpose of this study is to check the electrical installation in the building and determine the Energy Use Intensity (EUI) and the cost of payment according to usage based on historical data of the building then compare it with the EUI standard of Ministry of Energy and Mineral Resources of Indonesia. The method used is survey measurement method and quantitative descriptive analysis by comparing in general condition of energy consumption of this building with standard issued by Ministry of Energy and Mineral Resources of Indonesia. The EUI is average 645.58 kWh/m2/year, or 53.79 kWh/m2/month, this is inefficient category, because its EUI value is > 24 kWh / m2 / month. For Electrical audit on imaging thermal test at Panel Out Going of chiller pump, 200 ampere, the highest temperature is 97.3° C, at 200 ampere phase S termination, and this is included in the major category. The numbers of hot spots on the Capacitor bank panels are 10 major points and Chiller panel has 10 major. There are many major points and they are quite dangerous because they can cause fire hazard on the panel. The AC average temperature and humidity distribution did not meet the standard of SNI (Indonesia National Standard).
