Standing tall in the heart of Jakarta, Wisma 46 is more than just a city icon. Since 1996, it has graced the skyline as one of Indonesia’s most recognizable buildings. But recently, it has also become a symbol of how existing buildings can successfully transition into green, energy-efficient, and sustainable spaces.
With its Gold rating in the Greenship Existing Building certification by GBCI (Green Building Council Indonesia), Wisma 46 proves that sustainability is not only for new projects—but achievable for long-standing buildings too. And behind this transformation is the role of SUCOFINDO as the independent verifier.
Demand for Green, Not Just Grand
In today’s real estate market, buildings are no longer evaluated solely by investment value or location, but also by their environmental performance and alignment with ESG (Environmental, Social, Governance) criteria.
Office buildings are now expected to:
- Optimize energy and water usage
- Integrate waste management and recycling systems
- Enhance indoor comfort and lighting
- Meet national and international green standards
Those that fail to adapt will quickly fall behind in the competition for tenants, funding, and compliance.
Lack of Readiness and Understanding
Many property owners and building managers are unsure of where to begin:
- No baseline for energy or water consumption
- Lack of technical documentation for audits
- Concern that green building certification is costly or complex
- Misconception that only new buildings can be certified
Wisma 46 proves otherwise—it’s never too late to go green.
Case Study: How Wisma 46 Earned Its Gold Green Building Rating

Key achievements include:
- Energy efficiency at 197 kWh/m²/year, far below the SNI threshold of 250 kWh/m²/year
- Increased use of natural light and ventilation

These achievements were verified by SUCOFINDO, a trusted third party that conducted on-site inspections and validated the building’s sustainability claims.
