Measurement of Hotel Electrical Energy Consumption: Case Study of Hotels in Bandung

Abstract

As an archipelagic country, Indonesia has enormous Indonesian tourism potential which is being developed. This tourism potential needs to be supported by the availability of sufficient and comfortable hotels or accommodations which is in line with the availability of electrical equipment facilities. For lodging owners or lodging management, it is necessary to know the condition of electrical energy consumption in hotels, where the results obtained can be used as a consideration for determining room prices, as well as data on making improvements in the form of building energy optimization measures in hotels for good use of electrical energy. and efficient. Based on real-time measurement results, it is known that the average electrical energy consumption required for weekdays and weekend days is 111.21 kWh and 159.55 kWh. The total electrical energy for one week of observation at the hotel is 923.49 kWh with a total tariff of IDR 1,334,166,- which needs to be spent for one week, and with this value, it is known that the tariff for 1 month is IDR 5,336,664,- and IDR 64,039,968,- for one year. Based on the calculation results for scenario 2, the total electrical energy obtained for one week is 949.43 kWh with a total tariff of IDR 1,371,640,- which needs to be spent for one week, and with this value, it is known that the tariff for 1 month is IDR 5,486,560,- and IDR 65,838,723, - for one year, where there is a difference of 2.8%. Meanwhile, based on the results of assumptions in scenario 1 which is the maximum point of electrical energy use, and scenario 2 is the result of predictive assumptions which adjust the duration based on user habits, the average use of electrical energy at the Bumi-Sawunggaling Hotel is currently 28%.
