The adoption of sustainable practices in industrial facilities faces obstacles in terms of energy efficiency and property values. This study examines the impact of GreenShip Certification on the cost performance of a sustainable manufacturing facility in Jakarta, which aims for net-zero emissions by 2060. The methodology involves a cost-performance assessment and document review using GBCI ratings in six categories: Site Development, Energy Efficiency, Water Conservation, Material Resources, Indoor Health, and Environmental Management. The plant achieved platinum certification with a score of 87 out of 101. The findings showed a 58.14% reduction in energy consumption via sustainable passive design and renewable energy, resulting in 3427 t of annual carbon-dioxide emissions. Water conservation led to a 62.50% reduction, with efficient fixtures in 79.54% of locations. The plant uses prefabricated methods, non-toxic materials, and natural lighting, which aligns with green construction. The project was cost-effective, with the green design modification causing a cost overrun of 4.49% of the contract price, and the Final Cost-to-Initial Cost ratio was 103.22%. This study recommends a design approach that emphasizes effective cost planning from the outset to integrate sustainable design, energy management, and environmental awareness.
