Abstract
This study aims to investigate one of the benefits of retrofitting an existing educational building in its relation to the building’s life-cycle cost. Choosing educational building as a target of green retrofit project and as an object of study for its relevance as an important part of nationwide green project is considered timely, given the fact that there hasn’t been any retrofit project in Indonesia that targets educational building despite its necessity to create sustainable environmental management of educational facilities. The improvement made to the building by the project was measured using GREENSHIP Existing Building (EB), which is thelegitimate standard of assessment for the level of energy efficiency and conservation of buildings in Indonesia. Having been retrofitted, the building was rated Silver based on GREENSHIP EB rating system, and it wasa substantial progress compared to its previously non-rated status. The project had resulted in 0.45% decrease ofthe building’s total life-cycle cost. Furthermore, it was found that green retrofitting that was particularly oriented towards Energy Efficiency and Conservation, Water Conservation as well as Indoor Health and Comfort categories could cause greater life-cycle cost reduction than retrofitting that was undertaken for the whole categories prescribed in GREENSHIP EB.

Summary
Sejauh mana tingkat konservasi dan efisiensi energi pada gedung dapat terlihat pada poin yang dapat dihasilkan pada kategori Energy Efficiency and Conservation (EEC) yang memiliki kriteria Optimized Efficiency Building Energy Performance, Testing, Re-commissioning or Retro-commissioning, System Energy Performance, Energy Monitoring and Control, Operation and Maintenance, On Site Renewable Energy, dan Less Energy Emission. Tingkat konservasi sumber daya air dapat terlihat pada kategori Water Conservation (WC) yang terdiri dari 8 kriteria yaitu Water Sub-Metering, Water Monitoring Control, Fresh Water Efficiency, Water Quality, Recycled Water, Potable Water, Deep Well Reduction, dan Water Tap Efficiency. Aspek kenyamanan dan kesehatan dalam ruang terdapat pada kategori Indoor Health and Comfort (IHC) yang terdiri dari 9 kriteria, yaitu Outdoor Air Introduction, Environmental Tobacco Smoke Control, CO2 and CO Monitoring, Physical, Chemical and Biological Pollutants, Thermal Comfort, Visual Comfort, Acoustic Level, dan Building User Survey. Dimana FV adalah future value, r adalah rate of return dan n adalah number of periods
