Green Building and Cost Efficiency: Life Cycle Cost Study at ITSB Campus

This study examines the implementation of the green building concept at ITSB campus using life cycle cost (LCC) analysis. The focus of the research is to determine cost efficiency in the use of energy and water, as well as to identify the proportion of costs incurred throughout the building’s operational period. The results indicate that the initial investment dominates the total project cost, accounting for 92%. Despite the high initial investment, the application of environmentally friendly technologies in the building successfully reduced operational costs, particularly energy usage, resulting in savings of Rp 678,890,260. This study provides important insights for project planning in Indonesia, especially regarding sustainability, cost efficiency, and environmental impact.
