        "summary": "Sentral Senayan I, a Jakarta office building constructed in 1997, has achieved the prestigious Greenship Existing Building Platinum certification from the Green Building Council Indonesia, becoming the 504th green-certified structure in the country with a score of 90 points. This milestone, supported by a Rp 20 billion investment from PT Senayan Trikarya Sempana and Kajima Corporation, involved comprehensive audits and upgrades such as optimising the HVAC system and chiller, reducing energy consumption by over 12 percent, and revolutionising lighting with LEDs. The certification highlights the potential for older buildings to lead in decarbonisation efforts, setting a new standard for 1990s-era properties amid Indonesia's push for sustainable infrastructure.",
