Optimization of the Energy Management Concept in High Rise Office Building (Case Study in SSS Building Jakarta)

Energy Management Concept as part of Green Building Concept is focused to Improve Energy Efficiency Index (EEI) and Water Consumption Index (WCI). The purpose of this study was to determine how extent the implementation of green building principles in Office Buildings. The results show that the implementation of the Energy Management Concept could also made energy performance more efficient. After Implementing through Retrofitting of the Chiller System, Recycle Waste Water, Replacement of Conventional lamp to Energy Saving LED, and also Conduct Training as well as workshop to all employees and tenants so we can get the optimization of energy saving as well as the saving cost. Based on the comparing data before and after the implementation of Energy Management Concept, it is found that Energy Efficiency Index (EEI) decreased from 238.8 kWh/m
²
/year to 134,04 kWh/m
²
/year and the Water Consumption Index (WCI) from 50 liter/person/day to 27.18 Liter/person/day, the saving cost from electricity bill payments is IDR. 466,803,325.67/ month (18%) and roughly will Break Event Point (BEP) for 3.86 years, effectively.
