| description | The purpose of establishing a hotel building itself is expected to get good financial benefits as much as possible. In order to increase the cost-benefit for the building, increasing the energy efficiency is a major way to save energy and thus reduce energy expenses from the existing building. This research aim is to analyze energy consumption and cost-benefit at repaired existing hotel building. The method that used in this research are existing building modeling, energy and cost simulation, provide repairmen alternatives to reduce energy consumption and cost, and determine the optimum alternative design. The simulation using Sefaira as a Sketchup Software plug-in. In this research, the object is hotel building that have 11 floor and 1 basement at Yogyakarta, Indonesia. The result show that the existing hotel building consume 977 kWh/m2/year and energy cost IDR 2.994.403.821. The alternative for repairmen existing hotel building area the replacement of tint window, insulated wall application, skylight addition, and window addition at dismantle room area. For the selected alternative is the hybrid of window addition at dismantled room area and insulated wall that decrease energy consumption and cost into 871,06 kWh/m2/year (12,16%) and IDR 2.346.637.473 respectively. It means the energy cost savings is IDR 272.042.266 (9,09%). Furthermore, from cost-benefit analysis resulted the economic internal rate of return (EIRR) 13,61%, payback period in 5,52 years. In 20 years, PV Cost IDR 14.493.532.315,84 and PV benefit IDR 16.422.494.153,10, resulted the NPV at IDR 1.928.961.837,26 and BCR value 1.13. |
